AB  - Mushrooms are valued worldwide for their nutritional, organoleptic and chemical properties. The aim of this study was to determine the chemical composition (free sugars, organic acids, fatty acids, tocopherols and phenolic compounds) and bioactivity of three wild mushrooms (Lactarius piperatus, Lactarius quietus and Lactarius vellereus) from Serbia. Chemical analysis was performed with HPLC-RI and UFLC-PDA (for hydrophilic compounds) and with GC-FID and HPLC-FP (for lipophilic compounds). The analysis of phenolic compounds was performed by UFLC-DAD. Biological activities were evaluated using three different assays (microdilution, TBARS and SRB assays). The results showed that the fruiting bodies were rich in mannitol and trehalose. The main organic acids were oxalic acid and citric acid. As for lipophilic components, stearic, oleic and linoleic acids and β-tocopherol dominated in all the species studied. In addition, the methanolic and ethanolic extracts obtained showed antibacterial, antibiofilm and antioxidant properties. As for cytotoxicity, the extracts were not toxic or only moderately toxic toward different tumor cell lines. According to the results, the selected Serbian mushrooms are a rich source of bioactive compounds, and due to their good biological potential, they can be further exploited as functional ingredients beneficial to human health (antimicrobial agents, antioxidants).

AB  - Herein, we report the experimental evaluation of the antimicrobial activity of seventeen new (Z)-methyl 3-(4-oxo-2-thioxothiazolidin-5-ylidene)methyl)-1H-indole-2-carboxylate derivatives. All tested compounds exhibited antibacterial activity against eight Gram-positive and Gram-negative bacteria. Their activity exceeded those of ampicillin as well as streptomycin by 10-50 fold. The most sensitive bacterium was En. Cloacae, while E. coli was the most resistant one, followed by M. flavus. The most active compound appeared to be compound 8 with MIC at 0.004-0.03 mg/mL and MBC at 0.008-0.06 mg/mL. The antifungal activity of tested compounds was good to excellent with MIC in the range of 0.004-0.06 mg/mL, with compound 15 being the most potent. T. viride was the most sensitive fungal, while A. fumigatus was the most resistant one. Docking studies revealed that the inhibition of E. coli MurB is probably responsible for their antibacterial activity, while 14a-lanosterol demethylase of CYP51Ca is involved in the mechanism of antifungal activity. Furthermore, drug-likeness and ADMET profile prediction were performed. Finally, the cytotoxicity studies were performed for the most active compounds using MTT assay against normal MRC5 cells.

AB  - Introduction: The food industry increasingly utilizes plant extracts over synthetic antioxidants for preventing lipid oxidation, fighting foodborne pathogens, and prolonging shelf life of various products. The bioactive potential varies among plant species. Traditionally, extracts from rosehip fruits (Rosa canina L.) have preventive and curative effects on diabetes, memory disorders and cancer. In addition, these extracts are often used as antimicrobial, antinociceptive and anti-inflammatory agents.
Objective: The aim of this work was to investigate phytochemical composition and biological potential of aqueous extracts from the fruits of R. canina. 
Methodology: The lyophilized aqueous extract was analyzed using Agilent 1290 Infinity ultra-high performance liquid chromatography (UHPLC) system in conjunction with quadrupole time-of-flight mass spectrometry. The extracts were analyzed for total polyphenol and flavonoid content (TPC and TFC, respectively) using spectrophotometric methods. The biological activities of aqueous extracts were evaluated under in vitro conditions. The Ferric reducing antioxidant power (FRAP) and DPPH radical scavenging assay were used to investigate antioxidant potential. Antimicrobial activity was determined using microdilution assay and crystal violet and MTT tests were used for evaluation of antibiofilm activity.
Results and conclusions: R. canina fruit's aqueous extract had 32 phenolic compounds, which were classified into eight classes. Qualitative phytochemical analyses showed that this extract contained flavan-3-ols and procyanidins, dominated by epicatechin (624.354 mg/100g) and a proanthocyanidin dimer hexoside type B (457.016 mg/100g). Furthermore, extract was high in total phenolic content (412.25 TE mg/g) but low in total flavonoid compounds (0.73 QE mg/g). The highest antioxidant capacity was measured by FRAP assay (103.29 AAE mg/g), whereas notable antimicrobial properties were determined as well, with a standout 67.68% antibiofilm activity against Candida spp. at 0.5 MIC. These findings highlight potential of R. canina as a dietary source of antioxidants and antimicrobial agents.

AB  - Xanthium spinosum is a cosmopolitan annual herb used in traditional medicine worldwide. Although known from ethnobotanical studies, the species is scarcely investigated from the aspects of phytochemistry and biological activity. Therefore, the phenolic composition and biological activity of X. spinosum were examined. Plant specialised metabolites (phenolics) extracted from the roots, leaves and fruits with dichloromethane:methanol (1:1) were analysed by liquid chromatography mass spectrometry (LC-MS). In total 10 phenolic compounds were identified and quantified. Six compounds were common to all the extracts. Chlorogenic acid was the most abundant constituent in all the extracts (4.262 mg/g in the fruit extract, 0.820 mg/g in the leaf extract, and 0.540 mg/g in the root extract). The biological activity (antimicrobial and antibiofilm) of the extracts was tested against 12 microfungi and 12 bacterial strains by the microdilution method. All the extracts exhibited moderate antimicrobial and antibiofilm activity and inhibited the growth of most of the examined microorganisms. The obtained results indicate the potential role of the tested extracts in pharmacy and medicine.

AB  - Introduction: Different sugars are commonly used in the diet, but little is understood about the various effects of human health that they can affect. Hence, the impact of sugars and their substitutes used in diet on the development of virulence in Pseudomonas aeruginosa PAO1 was investigated. Sugars (fructose, demerara, coconut sugar, and cane sugar) and sugar substitutes (erythritol and stevia) were selected. The genes from three P. aeruginosa QS networks (las - lasI, lasR; rhl - rhlI, rhlR; PQS - pqsA, mvfR) were used for RT-qPCR analysis in order to investigate whether the expression of these genes changes. In this work, the focus is on the expression of genes involved in QS and the ability to form biofilms (a type of structured community of microorganisms that is attached to the surface and connected by an exopolysaccharide matrix), as well as determining minimal inhibitory concentration of antibiotics in presence of tested compounds.
Methods: Microdiltuion assay, Antibiofilm assay, RT- qPCR
Results: In the presence of tested sugars and their substitutes, the minimum inhibitory concentration of commercial antibiotics increased, as well as the percentages of biofilm formation (for instance, the percentage of biofilm formation is 171% in the presence of coconut sugar). Furthermore, exposure of P. aeruginosa to tested compounds caused the greatest increase in expression of virulence associated with the lasI and pvdF genes.
Conclusion: More awareness and research is needed to highlight the effects sugars can have on P. aeruginosa and to propose new strategies to reduce this negative aspect.

AB  - Kontinuirani rast tržišta piva i alkoholnih pića otvorio je nove mogućnosti za poboljšanje ukusa, arome i korisnosti ovih napitaka. Već hiljadu godina unazad je poznato da dodavanje različitih biljnih sastojaka u piće menja njihov ukus i svojstva. Međutim, moderna tehnologija olakšava postizanje željenih karakteristika i nudi nove mogućnosti za terapeutske efekte i senzorna poboljšanja ovog tradicionalnog pića.
U ovom radu su predstavljene hemijska analiza i bioaktivna svojstva etanolnog i vodenog ekstrakta Prunus spinosa L. (trnjine) kao potencijalnog dodatka pivu, sa ciljem povećanja funkcionalnih karakteristika i senzornih osobina ovog napitka.
Hemijske analize korišćenjem UHPLC-QToF-MS pokazale su prisustvo: derivata hidroksibenzoeve kiseline (heksozid vanilinske kiseline do 141.476 mg/100 g ekstrakta), derivata hidroksicimetne kiseline (izomer kafeoilkvinske kiseline do 306.608 mg/100 g ekstrakta, feruloilkvinske kiseline do 225.884 mg/100 g ekstrakta) i derivata flavona (apigenin 180.094 mg/100g ekstrakta).
Procena bioaktivnih svojstava nesumnjivo je pokazala da oba ekstrakta trnjine imaju umeren do dobar antimikrobni potencijal, kao i sposobnost da inhibiraju formiranje biofilma, pri čemu je etanolni ekstrakt pokazao sveukupni bolji potencijal u inhibiciji rasta mikroorganizama. Najbolji antimikrobni potencijal je pokazan kod vodenog ekstrakta prema Bacillus cereus koja je poznati patogen identifikovan u namirnicama (MIC 0.5 mg/mL, MBC 1.00 mg/mL), dok su druge testirane bakterije bile otpornije na aktivnost testiranih ekstrakata (MIC u opsegu od 1.0- 4.0 mg/mL i MBC u opsegu od 2.00-8.00 mg/mL). Rezultati antifungalne aktivnosti su pokazali da ekstrakti prilično ujednačeno deluju inhibitorno na rast testiranih mikrogljiva, uz MIK vrednosti 1.00 mg/mL i MFK 2.00 mg/mL. Detaljnija analiza antimikrobne aktivnosti pokazala je da testirani ekstrakti trnjine značajno inhibiraju formiranje biofilma Candida albicans ATCC 10231; oba testirana uzorka su inhibirala formiranje biofilma na subinhibitornim koncentracijama približno 67.00 %. Uočena aktivnost se može pripisati prisustvu različitih fenolnih jedinjenja.
Imajući u vidu poznat gorak ukus P. spinosa kao i pokazana bioaktivna svojstva njegovih ekstrakata, verujemo da bi ova biljka bila odličan funkcionalni sastojak koji će se dobro uklopiti u jedinstvena senzorna svojstva piva i sličnih napitaka. Predloženo pivo bi čak moglo da pruži dodatne zdravstvene efekte potrošačima, balansirajući između zadovoljstva i njihove želje za zdravim sastojcima.
AB  - The continuous growth of beer and beverage market has opened new opportunities to improve their flavor, aroma, and benefits. It has been known for thousands of years that adding various herbs to beer changes the taste and properties of this beverage. However, modern technology makes it easier to achieve the desired properties and provides useful qualities for therapeutic effects and sensory improvement of traditional beer. This paper presents chemical analysis and bioactive properties of ethanolic and aqueous extract of Prunus spinosa L. (blackthorn) as a potential ingredient for beer to improve functional and sensory properties of this beverage.
Chemical analyses by UHPLC-QToF-MS revealed presence of: hidroxybenzoic acid derivatives (vanillic acid hexoside up to 141.476 mg/100g extract), hidroxycinnamic acid derivatives (caffeoylquinic acid isomer up to 306.608 mg/100g extract and feruloylquinic acid up to 225.884 mg/100g extract) and flavone derivatives (apigenin 180.094 mg/100g extract).
The evaluation of bioactive properties undoubtedly showed that both blackthorn extracts have moderate to rather good antimicrobial and antibiofilm potential, with ethanolic extract being slightly better in terms of inhibiting microbial growth. The best antimicrobial potential was observed with aqueous extract towards foodborne pathogenic bacteria Bacillus cereus (MIC 0.5 mg/mL, MBC 1.00 mg/mL), whereas other tested bacteria were more resilient towards the activity of the tested extracts (MIC in range of 1.0-4.0 mg/mL and MBC in range of 2.00-8.00 mg/mL). In terms of antifungal potential, the extracts showed rather uniform inhibitory effects towards tested microfungi with MIC value 1.00 mg/mL and MFC 2.00 mg/mL. A more in depth analysis of antimicrobial activity showed that the tested blackthorn extracts have promising antibiofilm activity towards Candida albicans ATCC 10231 as well, with both samples inhibiting formation of biofilm at subinhibitory levels approximately 67.00 %. Observed activity may be attributed to the presence of various phenolic compounds. 
Considering the well-known bitter taste of P. spinosa and demonstrated bioactive properties of its extracts, we believe it would be a great functional ingredient to add to the unique sensory properties of beer and similar beverages. This beer may even be able to provide consumers with additional health benefits, balancing enjoyment with the desire for healthy ingredients.

Već hiljadu godina unazad je poznato da dodavanje različitih biljnih sastojaka u piće menja njihov ukus i svojstva. Međutim, moderna tehnologija olakšava postizanje željenih karakteristika i nudi nove mogućnosti za terapeutske efekte i senzorna poboljšanja ovog tradicionalnog pića.

AB  - Flavonoids are secondary metabolites abundantly present in plants and, in most cases, essential contributors to plants bioactivity. They have been studied so far for a range of possible health-beneficial effects, including antioxidant, cardioprotective, and cytotoxic. Therefore, there are data on the antimicrobial potential of a significant number of flavonoids. However, less is known regarding their antivirulence traits. Trending antimicrobial research worldwide has pointed out the promising effects of antimicrobial strategies based on the antivirulence principle, so this review aims to present the newest research regarding the antivirulence effects of flavonoids. Articles on antivirulence flavonoids published from 2015 until now were selected. A range of molecules from this class has been studied up to date, with the most abundant data for quercetin and myricetin, while the most studied organism is Pseudomonas aeruginosa</i>. The antivirulence attributes studied included antibiofilm assessment, followed by data on the inhibition of virulence pigments (pyocyanin, violacein, and staphyloxanthin) and virulence enzyme production (such as sortase A and elastase). Less information is collected on the inhibition of morphological transition, motility, and molecular mechanisms underlying the antivirulence properties of flavonoids and in vivo</i> research. Flavonoids are a group of compounds with a wide range of antivirulence traits and might be further developed into essential parts of novel antimicrobial strategies.

AB  - The purpose of this study was to evaluate the surface texture and biofilm adhe sion of veneered or CAD/CAM milled zirconia (partially stabilized with yttrium) after professional
oral hygiene procedures. The samples (4 × 4 mm, thickness 2 mm; n = 72) were separated from
zirconia blanks (3Y-TZP-LA). One group was veenered with ceramics, and the other group of samples
was CAD/CAM milled. Each group had two subgroups: polished and glazed. The samples were
subjected to simulated strokes of professional brushing using abrasive paste and ultrasonic scaling.
The parameters of surface micromorphology and receptivity to biofilm were calculated before and
after simulating the given methods of the professional maintenance of oral hygiene. Scanning electron
microscopy (SEM) was used to evaluate zirconia surface properties. Microbial (bacterial/fungal)
species (Staphylococcus aureus, Streptococcus sanguinis and Candida albicans) were used and cultured
on respective sterilized zirconia surfaces. Colony-forming unit (CFU) counts were used to quantify
the amount of biofilm formation on zirconia samples surfaces. Results: The SEM analysis showed
the greatest change in surface microtopography after the use of ultrasonic scaling on glazed zirconia
samples. Less formation of colonies on the surfaces of CAD/CAM milled zirconia restorations was
observed. Conclusion: Routine methods of oral hygiene professional maintenance can damage the
surfaces of glazed zirconia restorations.

AB  - Spiked centaury (Centaurium spicatum) is a well-known medicinal plant from the Mediterranean region with various bioactivities, but there are no studies addressing the use of different solvent systems to improve its pharmacological potential. Nine extraction procedures were adapted to study the effects of solvent composition on the content of bioactive compounds in C. spicatum extracts and on corresponding bioactivities. Targeted metabolomics was performed to obtain information on the chemical composition of extracts. Ethanol-water-based extraction procedures were the most efficient in isolating polyphenols, while less polar butanol extract contained the highest amount of iridoids. Antioxidant potential analysis revealed stronger activity in extracts with higher polyphenol content. Bacillus cereus and Staphylococus aureus were designated as the most sensitive bacterial strains to the activity of extracts, while among the micromycetes tested, Penicillium funiculosum was the most susceptible strain. Butanol extract showed antivirulence potential on Candida albicans morphological transition from yeast to hyphal form, and selected extracts were effective against biofilm formation in two Candida species. All the extracts tested in this study showed no cytotoxic activity to immortalize human skin keratinocyte cell line (HaCaT), whereas extracts obtained by ethanol-water extraction stand out for their potent wound healing effects. Moreover, the influence of the extraction solvent system on various bioactivities of C. spicatum is reported herein for the first time. Overall, the results presented in this study promote the use of C. spicatum as a source of natural products with potential antioxidant, wound healing, and antimicrobial applications that are potentially safe for human use.

AB  - A variety of the classic green tea plant, Camellia sinensis, was developed and is exclusive to Kenya. Due to high content of anthocyanin polyphenols in its leaves, the beverage obtained from this variety is purple in color and is the origin of the name purple tea. This work had two main purposes. The first one was to identify and quantify the major anthocyanin polyphenols in a hot water aqueous extract of the purple tea leaves. The second one was to test the hypothesis if this extract is capable of inhibiting triglyceride absorption considering that anthocyanin polyphenolics have been frequently associated to antilipidemic effects. Parallel experiments were always done with a similar green tea extract for comparison purposes. The antioxidant, anti-inflammatory, and cytotoxic activities of both tea varieties are similar. The purple tea extract, however, was strongly inhibitory toward the pancreatic lipase (minimal IC50 = 67.4 μg mL-1), whereas the green tea preparation was a weak inhibitor. Triglyceride digestion in mice was inhibited by the purple tea extract starting at 100 mg kg-1 dose and with a well-defined dose dependence. Green tea had no effect on triglyceride digestion at doses up to 500 mg kg-1. The latter effect is probably caused by several components in the purple tea extract including non-anthocyanin and anthocyanin polyphenols, the first ones acting solely via the inhibition of the pancreatic lipase and the latter by inhibiting both the lipase and the transport of free fatty acids from the intestinal lumen into the circulating blood. The results suggest that the regular consumption of Kenyan purple tea can be useful in the control of obesity.

AB  - .Global health and modern medicine are facing a worldwide issue nowadays – antimicrobial resistance of microorganisms. A great interest in the pursuit of bioactive compounds from plants that can be antimicrobial drugs has been triggered due to multidrug resistance in pathogenic microorganisms and undesirable side effects of certain antibiotics (Alviano & Alviano, 2009). Ethnobotanical data suggest that many Centaurea species are traditionally used for treatment of various ailments in people and animals, as well as for nourishment (Khammar & Djeddi, 2012). Extracts obtained from Centaurea exhibit wide range of biological activity (Khammar & Djeddi, 2012) with a numerous studies concerning antimicrobial activity (Güven et al., 2005; Karamenderes et al., 2006; Özcan et al., 2019; Dimkić et al., 2020). Centaurea glaberrima Tausch (Asteraceae), Circum - Mediterranean Clade sensu Hilpold et al. (2014), is an endemic plant species that inhabits fields as well as a rocky cliffs and waste places in the West Balkans (Dostál, 1976). There is no information on biological activity of C. glaberrima therefore the aim of this study was to investigate antimicrobial potential of ethyl acetate extract of this endemic species.

AB  - The frequency of resistance to a large number of antimicrobial agents is increasing, so there
is a need to find new ones. A major problem in the treatment of infections caused by Candida
albicans is a highly resistant biofilm, which is a virulence factor of this species. The
mechanisms of action of selected flavonoids (hesperetin, sakuranetin, and taxifolin) on
species of the genus Candida were explored. The strains that were tested were C. albicans
10/15, C. albicans 13/15, C. albicans ATCC 10231, C. albicans 475/15, C. parapsilosis
ATCC 22019, C. tropicalis ATCC 750, C. krusei H1/16, and C. glabrata 4/6/15. The
antimicrobial potential of flavonoids was investigated by the microdilution method.
Determining the ability of these compounds to disrupt virulence factors, in the model of
Candida albicans, is based on monitoring the process of disrupting the formation and
destruction of previously formed biofilm. The cytotoxic effect on selected human cell lines
(lung fibroblasts) was investigated in order to determine whether flavonoids are selectively
toxic to species of the genus Candida, or cause non-selective toxicity in eukaryotic cells. The
laboratory methods used were microdilution method, antibiofilm method (crystal violet assay,
measures biofilm biomass), Congo red binding assay (measures the influence of compounds
on exopolysaccharide, EPS, production in biofilm), MTT cytotoxicity assay. The most
pronounced antifungal potential was observed for sakuranetin with a MIC of 0.041 mg/mL
for C. parapsilosis ATCC 22019 and a MIC of 0.082 mg/mL for the other strains tested. The
antimicrobial potential of hesperetin and taxifolin is the same for all tested strains; MIC value
is 0.165 mg/mL. All substances have been shown to be effective in inhibiting biofilm
formation, but also in destroying it. The antibiofilm effect of sakuranetin applied in
concentration equal to MIC against C. glabrata 4/6/15 and C. krusei H1/16 is over 85%.
These two strains are the most sensitive to the action of sakuranetin. The ability to destroy the
previously formed biofilm was pronounced towards C. albicans 475/15 (52.80%), and
moderate towards C. albicans ATCC 10231 (12.22%). The antibiofilm potential of hesperetin
is high for C. glabrata 4/6/15 (70.4%) and C. parapsilosis ATCC 22019 (62.6%), while for
other strains the percentage of inhibition is less than 50%, and for the formation of biofilm C.
krusei H1/16 hesperetin has no effect at all. The distinct effect of this flavonoid on the
destruction of previously formed biofilm is emphasized, with significant percentages of
destruction, while the percentages of EPS inhibition are low but significant (higher or closer
to the effect of ketoconazole). The most pronounced antibiofilm effect of taxifolin is
exhibited towards C. glabrata 4/6/15 (61.6%), while the percentage of inhibition is not higher
than 50% for other strains, which is generally lower effect than for other tested substances.
The cytotoxicity test indicates the following range of sensitivity of the examined cell line to
flavonoids: sakuranetin>hesperetin>taxifolin. The tested flavonoids have excellent potential
to be part of antifungal therapies, especially hesperetin, which has shown a strong antibiofilm
effect with pronounced selectivity towards pathogen cells.

AB  - Chicory (Cichorium intybus L.) is an important industrial crop cultivated mainly to extract the
dietary fiber inulin. This study aimed to investigate antimicrobial, antibiofilm and wound healing
potentials of the extract obtained by supercritical fluid extraction (SFE). Antibacterial activity
of extract ranged from 0.25 to 4.00 mg/mL regarding minimal inhibitory concentra-tions (MICs),
while minimal bactericidal concentrations (MBCs) were noted within the range of 0.5 to 8.00 mg/
mL. The extract has shown promising antifungal potential with MICs rang-ing 0.125- 0.75 mg/
mL and MFCs 0.25-1.0 mg/mL against Candida species. Incubation with the extract has reduced
the ability of both C. albicans and P. aeruginosa to attach to the sur-face and begin the process
of biofilm formation. Concentration equal to previously deter-mined MIC has almost completely
(>90% inhibition) reduced the biofilm biomass formed by P. aeruginosa. Even twice as lower concentrations
(0.5 MIC) has limited the biofilm forming ability and induce more than 80% inhibition
in P. aeruginosa as bacterial biofilm model or-ganism. Impact on fungal biofilm was less profound
and MIC concentration was able to re-duce the biofilm formation for less than 60%. HaCaT (human
immortalized keratinocytes cell line) cells were treated with IC20 (24 h) concentration of chicory
SFE extract. It is estimated that SFE extract has slight effect on wound closure in keratinocyte
monolayer, when com-pared to untreated control. Since, Chicory SFE fraction possessed excellent
antibacterial po-tential against E. coli and K. pneumoniae and antifungal activity against Candida
species these results are considered very important in the future inventions

AB  - Emerging antimicrobial resistance and side effects associated with antibiotics overuse are driving the need for the novel antimicrobial therapeutics with the natural compounds considered as an appealing alternative. Rosmarinic acid is abundantly present in medicinal plants. This study aimed to elucidate its possible role as an inhibitor of planktonic and biofilm microorganism growth, along with its antifungal mechanisms. In this study, rosmarinic acid showed promising anticandidal (MIC 0.1–0.2 mg/mL) and antibacterial (MIC 0.002->0.8 mg/mL) activity. To some extent it was able to prevent cell attachment and eradicate established biofilms. Rosmarinic acid antifungal mechanisms included reduction of mitochondrial activity, alteration in membrane integrity, and slight inhibition of protease production but not binding to ergosterol. Its antibiofilm activity was moderately linked to the reduction in exopolysaccharide production. Considering its wide antimicrobial and antibiofilm spectrum rosmarinic acid could be further explored as an antimicrobial agent along with range of medicinal plants with rosmarinic acid as the dominant compound. Nevertheless, rosmarinic acid could serve as the basis for the development of antimicrobials employing novel mechanisms of activity.

AB  - Cichorium intybus L. (Asteraceae), is an important medicinal plant, rich in sesquiterpene
lactones (STLs), inulin, biologically relevant elements, and vitamins which exert potent
pro-health effects on the human organism. The aim of this study was to screen two
extracts of chicory containing STLs, the optimized extract (Ci_SFEopt) and the
supercritical fluid extract (Ci_SFEpur), for their antimicrobial activities against a range
of pathogenic microorganisms. Both extracts showed antibacterial activity, with
Ci_SFEpur being more potent than Ci_SFEopt. The most sensitive species was
Pseudomonas aeruginosa (minimal inhibitory concentration, MIC 0.06 mg/mL).
Ci_SFEpur and Ci_SFEopt extracts demonstrated good antifungal activity against
Candida species (MIC 0.03-1.00 mg/mL). Thin layer chromatography (TLC)
bioautography was used to screen the extracts and provide basic information for the
isolation of bioactive compounds in the future. Ci_SFEopt was active against all tested
microorganisms (Rf values were 0.18-0.88). The Ci_SFEpur extract efficiently inhibited
(Rf 0.76) Staphylococcus aureus, P. aeruginosa and Candida krusei. The identification
of powerful antimicrobial activity of Ci_SFEpur against P. aeruginosa and Candida
species is an important step towards the development of novel antimicrobial therapeutics
and efficient utilization of this widely distributed plant.

AB  - Mushrooms are highly appreciated for their nutritional value and therapeutic effects. They have found wide application in pharmacy, medicine and as nutraceuticals, mostly due to the synergistic activity of their bioactive compounds. This study aimed to investigate the chemical composition and antioxidant, antibacterial, antibiofilm, and cytotoxic potential of L. piperatus and L. vellereus wild growing mushrooms from Serbia. Mannitol and trehalose were the most abundant free sugars and malic and citric acid were the major organic acids detected. The four tocopherol isoforms were found in L. piperatus, and the β-tocopherol was the only tocopherol isoform found in the L. vellereus fruiting body. Regarding phenolic compounds, cinnamic and protocatechinic acids were identified in the prepared methanolic and ethanolic extracts, which displayed antioxidant activity through the inhibition of thiobarbituric acid reactive substances (TBARS) formation (IC50 0.30-1.39 mg/mL). Antibacterial activity of Lactarius ethanolic and methanolic extracts was investigated against bacteria isolated from tonsils from the patient with chronic tonsillitis. All tested extracts demonstrated promising results regarding antibacterial and antibiofim activity. In both extracts, the most promising activity was observed for Streptococcus spp. (0.40–6.25 mg/mL as the minimal inhibitory concentration). Ethanolic extracts of tested mushrooms showed a stronger potential to inhibit the formation of Staphylococcus aureus biofilm then methanolic. L. vellereus ethanolic extract showed highest inhibition activity (86%) against S. aureus biofilm formation. Citotoxic potential of L. piperatus and L. vellereus extracts were examined against four tumor cell lines (HeLa, MCF-7, HepG2, NCI-H460) and porcine liver primary culture - PLP2. The most promising cytotoxic effect was caused by the L. vellereus ethanolic extract on cervical carcinoma cell line (HeLa). However, extensive screening of biological activities is needed in future studies that will allow the exploitation of these mushrooms at an industrial level, taking advantage of its benefits for human health.

AB  - Chronic tonsillitis (CT) is a global health issue which can impair patient’s quality of life and has an important socioeconomic impact due to the nonrational use of antibiotics, increased antimicrobial resistance and frequent need for surgical treatment. In order to isolate and identify the causing agents of CT, a total of 79 postoperative palatine and adenoid tissue samples were obtained from the ENT Clinic, KBC Zvezdara, Belgrade, Serbia. Culture identification was performed by MALDI-TOF MS and the Staphylococcus aureus isolates were tested for biofilm forming capability and antibiotic susceptibility. Additionally, a histological examination of palatine and adenoid tissue was performed in order to detect the presence of CT-causing bacteria. The slight majority of participants were females with median age of 28 years for adult patients (group I) and 6 years for children (group II). Analysis of the incidence of bacteria isolated from tissue samples in both groups showed the highest prevalence of S. aureus, Streptococcus oralis and Streptococcus parasanquinis. In addition to interfollicular hyperplasia, colonies of species S. aureus were detected in histological material. The presence of biofilm might be the reason for the recurrence of infection. Therefore, searching for a new treatment of CT is of great importance.

AB  - Herein, we report computational and experimental evaluations of the antimicrobial activity of twenty one 2,3-diaryl-thiazolidin-4-ones. All synthesized compounds exhibited an antibacterial activity against six Gram-positive and Gram-negative bacteria to different extents. Thus, the MIC was in the range of 0.008–0.24 mg/mL, while the MBC was 0.0016–0.48 mg/mL. The most sensitive bacterium was S. Typhimurium, whereas S. aureus was the most resistant. The best antibacterial activity was observed for compound 5 (MIC at 0.008–0.06 mg/mL). The three most active compounds 5, 8, and 15, as well as compound 6, which were evaluated against three resistant strains, MRSA, P. aeruginosa, and E. coli, were more potent against all bacterial strains used than ampicillin. The antifungal activity of some compounds exceeded or were equipotent with those of the reference antifungal agents bifonazole and ketoconazole. The best activity was expressed by compound 5. All compounds exhibited moderate to good drug-likeness scores ranging from −0.39 to 0.39. The docking studies indicated a probable involvement of E. coli Mur B inhibition in the antibacterial action, while CYP51 inhibition is likely responsible for the antifungal activity of the tested compounds. Finally, the assessment of cellular cytotoxicity of the compounds in normal human MRC-5 cells revealed that the compounds were not toxic. View Full-Text

AB  - If chronic tonsillitis (CT) is treated surgically, the long-term risks of infections and respiratory diseases are
higher, making of high importance to find an alternative for tonsillectomy. In order to isolate and identify
the causing agents of CT, a total of 79 postoperative palatine and adenoid tissue samples were obtained
from the ENT Clinic, KBC Zvezdara. A total of 82 bacterial species were isolated and identified by MALDI-TOF.
They belong to the genera Streptococcus, Staphylococcus, Micrococcus, Rothia, Enterobacter and Stenotrophomonas.
Analysis of the incidence of bacteria isolated from tissue samples showed the highest prevalence of Streptococcus
oralis (27/33%), followed by S. aureus (17/21%) and Streptococcus parasanquinis (16/20%). Histological analysis
of tissue samples was conducted in order to detect the presence of CT-causing bacteria. In addition to interfollicular
hyperplasia, colonies of species S. aureus and Stenotrophomonas maltophilia were detected in histological material.
The presented results confirm that the colonizers of tonsils tissues can be both G (+) and G (-) bacteria. The
presence of S. aureus in the tonsillar tissue even after the antibiotic therapy may be related to its ability to
form biofilm. Our study demonstrated that among 17 S. aureus isolates, 13 displays more pronounced biofilm
forming ability than the reference strain S. aureus ATCC 11632, and only 4 isolates display lower biofilm forming ability.
The presence of biofilm might be the reason for the recurrence of infection. Therefore, a searching for new
antibiofilm therapeutics in CT therapy is of great importance.

higher, making of high importance to find an alternative for tonsillectomy. In order to isolate and identify
the causing agents of CT, a total of 79 postoperative palatine and adenoid tissue samples were obtained
from the ENT Clinic, KBC Zvezdara. A total of 82 bacterial species were isolated and identified by MALDI-TOF.

AB  - Hesperetin is the aglycone of citrus flavonoid hesperidin. Due to the limited information regarding hesperetin antimicrobial potential and emerging need for novel antimicrobials, we have studied its antimicrobial activity (microdilution assay), antibiofilm activity with different assays in two models (mono- and polymicrobial biofilm), and toxicity (MTT and brine shrimp lethality assays). Hesperetin inhibited growth of all Candida isolates (minimal inhibitory concentration, MIC, 0.165 mg/mL), while it’s inhibitory potential towards Staphylococcus aureus was lower (MIC 4 mg/mL). Hesperetin (0.165 mg/mL) reduced ability of Candida to form biofilms and moderately reduced exopolysaccharide levels in biofilm matrix. Effect on the eradication of 24 h old C. albicans biofilms was promising at 1.320 mg/mL. Inhibition of staphylococcal biofilm formation required higher concentrations of hesperetin (<50% inhibition with MIC 4 mg/mL). Establishment of polymicrobial C. albicans-S. aureus biofilm was significantly inhibited with the lowest examined hesperetin concentration (1 mg/mL) in crystal violet and CFU assays. Hesperetin toxicity was examined towards MRC-5 fibroblasts (IC50 0.340 mg/mL) and in brine shrimp lethality assay (LC50 > 1 mg/mL). Hesperetin is efficient in combating growth and biofilm formation of Candida species. However, its antibacterial application should be further examined due to the cytotoxic effects provoked in the antibacterial concentrations

AB  - Herein we report the design and synthesis of thiazolo[4,5-b]pyridin-5-ones and evaluation of their antimicrobial activity. The design was based on a molecular hybridization approach. Evaluation of their antibacterial activity revealed that these compounds generally showed moderate antibacterial activity. The best activity was achieved for compound 4p with MIC/MBC in the range of 0.12-0.47 and 0.23-0.94 mg mL(-1) respectively. Three compounds (4g, 4n, and 4p) were tested against three resistant strains, namely MRSA, p.aeruginosa, and E.coli, showing higher inhibition potential than the reference drug ampicillin. These three compounds also were tested for their ability to inhibit biofilm formation, with two of them showing better activity than streptomycin in a concentration of MIC (4p) and ampicillin in both concentrations (MIC and 0.5 MIC). As far as antifungal activity is concerned, the best activity was observed for compound 4i with MIC at 0.12-0.47 mg mL(-1) and MFC at 0.23-0.94 mg m(-1). According to docking studies, the predicted inhibition of E.coli MurB enzyme is probably a putative mechanism of the antibacterial activity of these compounds, while inhibition of 14a-lanosterol demethylase is probably the mechanism of their antifungal activity.

AB  - Emerging antimicrobial resistance and side effects associated with antibiotics overuse are driving the need for the novel antimicrobial therapeutics with the natural compounds considered as an appealing alternative. Rosmarinic acid is abundantly present in medicinal plants. This study aimed to elucidate its possible role as an inhibitor of planktonic and biofilm microorganism growth, along with its antifungal mechanisms. In this study, rosmarinic acid showed promising anticandidal (MIC 0.1–0.2 mg/mL) and antibacterial (MIC 0.002->0.8 mg/mL) activity. To some extent it was able to prevent cell attachment and eradicate established biofilms. Rosmarinic acid antifungal mechanisms included reduction of mitochondrial activity, alteration in membrane integrity, and slight inhibition of protease production but not binding to ergosterol. Its antibiofilm activity was moderately linked to the reduction in exopolysaccharide production. Considering its wide antimicrobial and antibiofilm spectrum rosmarinic acid could be further explored as an antimicrobial agent along with range of medicinal plants with rosmarinic acid as the dominant compound. Nevertheless, rosmarinic acid could serve as the basis for the development of antimicrobials employing novel mechanisms of activity.

AB  - In this manuscript, we describe the design, preparation, and studies of antimicrobial activity of a series of novel heteroarylated benzothiazoles. A molecular hybridization approach was used for the designing compounds. The in vitro evaluation exposed that these compounds showed moderate antibacterial activity. Compound 2j was found to be the most potent (MIC/MBC at 0.23-0.94 mg/mL and 0.47-1.88 mg/mL) On the other hand, compounds showed good antifungal activity (MIC/MFC at 0.06-0.47 and 0.11-0.94 mg/mL respectively) with 2d being the most active one. The docking studies revealed that inhibition of E. coli MurB and 14-lanosterol demethylase probably represent the mechanism of antibacterial and antifungal activities.

AB  - Composition and antimicrobial activity of root, leaf, stem, flower and fruit essential oils from cultivated Pastinaca sativa subsp. sativa, and its two wild-growing relatives P. sativa subsp. urens and P. hirsuta (Apiaceae) were investigated. Twenty-nine hydrodistilled essential oils of plants from different localities and/or years were analysed by GC-FID and GC/MS. Dominant in root oils was myristicin (P. sativa) or apiole (P. hirsuta), in leaf and stem oils myristicin (cultivated plants) or γ-palmitolactone (wild-growing plants) and in flower and fruit oils aliphatic esters. Multivariate statistics (PCA, nMDS, UPGMA clustering) generally revealed separation of oils of investigated Pastinaca taxa and demonstrated their chemosystematic significance. One oil per each organ of all three plants (fifteen in total) was tested using microdilution method for activity against Candida tropicalis, C. parapsilosis, C. krusei, C. glabrata, C. albicans, Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Escherichia coli, Salmonella Typhimurium and Enterobacter cloacae; MIC = 0.25–8 mg/mL, MBC(MFC) = 0.5–16 mg/mL
