AB  - Nonsteroidal anti-inflammatory drugs (NSAIDs) such as nimesulide have shown
antitumor effects against different types of tumor cell lines. The potential cytotoxic effect
of isonimesulide, a member of the nimesulide family, and its carborane derivatives
was determined against HT29, HCT116, MCF-7, A375, and A549 human cell lines. The
viability of all tested cell lines was dose-dependently decreased as shown by 3-(4,5-dimethythiazol-
2-yl)-2,5-diphenyltetrazolium bromide and crystal violet assays. The selectivity
of these compounds toward a tumor phenotype was demonstrated on MRC-5
and peritoneal exudate cells under identical experimental conditions. Flow cytometric
analysis revealed a significant reduction in the division potential of MCF-7 cells treated
with isonimesulide and two selected carborane derivatives (4a and 4b). Subsequently,
isonimesulide carborane derivatives induced strong apoptosis which was not mediated by
caspase activation. On the other hand, isonimesulide initiated caspase-mediated apoptosis
and reduced proliferation at a significantly lower rate than its carborane derivatives. In
further investigations, intensive apoptosis manifested with the irregular shape of nuclei,
and chromatin condensation was confirmed by propidium iodide (PI) staining of treated
MCF-7 cells using fluorescent microscopy. Finally, the inhibited production of reactive
oxygen and nitrogen species (ROS/RNS) was observed only in the case of 4b. The new features
of isonimesulide and its carborane derivatives are reflected in their strong antitumor
potential, which opens numerous possibilities for further research.

AB  - Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most widely used
therapeutics against pain, fever, and inflammation; additionally, antitumor
properties are reported. NSAIDs reduce the synthesis of prostaglandins by
inhibiting the cyclooxygenase (COX) isoforms COX-1 and COX-2. As
nonselective inhibition is associated with off-target effects, strategies to
achieve selectivity for the clinically preferred isoform COX-2 are of high
interest. The modification of NSAIDs using carborane clusters as phenyl
mimetics is reported to alter the selectivity profile through size exclusion.
Inspired by these findings, isonimesulide and its carborane derivatives are
prepared. The biological screening shows that the carborane containing
compounds exhibit a stronger antitumor potential compared to nimesulide
and isonimesulide. Furthermore, the replacement of the phenyl ring of
isonimesulide with a carborane moiety resulted in a shift of the COX activity
from nonactive to COX-active compounds.

AB  - Fenoprofen is a widely used nonsteroidal anti-inflammatory drug (NSAID) against rheumatoid arthritis, degenerative joint disease, ankylosing spondylitis and gout. Like other NSAIDs, fenoprofen inhibits the synthesis of prostaglandins by blocking both cyclooxygenase (COX) isoforms, COX-1 the “house-keeping” enzyme and COX-2 the induced isoform from pathological stimuli. Unselective inhibition of both COX isoforms results in many side effects, but off-target effects have also been reported. The steric modifications of the drugs could afford the desired COX-2 selectivity. Furthermore, NSAIDs have shown promising cytotoxic properties. The structural modification of fenoprofen using bulky dicarba-closo-dodecaborane(12) (carborane) clusters and the biological evaluation of the carborane analogues for COX inhibition and antitumor potential showed that the carborane analogues exhibit stronger antitumor potential compared to their respective aryl-based compounds.

AB  - Mefenamic acid represents a widely used nonsteroidal anti-inflammatory drug (NSAID) to treat the pain of postoperative surgery and heavy menstrual bleeding. Like other NSAIDs, mefenamic acid inhibits the synthesis of prostaglandins by nonselectively blocking cyclooxygenase (COX) isoforms COX-1 and COX-2. For the improved selectivity of the drug and, therefore, reduced related side effects, the carborane analogues of mefenamic acid were evaluated. The ortho-, meta-, and para-carborane derivatives were synthesized in three steps: halogenation of the respective cluster, followed by a Pd-catalyzed B-N coupling and hydrolysis of the nitrile derivatives under acidic conditions. The COX inhibitory activity and cytotoxicity for different cancer cell lines revealed that the carborane analogues have stronger antitumor potential compared to their parent organic compound.

AB  - All over the world, societies are facing rapidly aging populations combined with a growing number of patients suffering from Alzheimer’s disease (AD). One focus in pharmaceutical research to address this issue is on the reduction of the longer amyloid-β (Aβ) fragments in the brain by modulation of γ-secretase, a membrane-bound protease. R-Flurbiprofen (tarenflurbil) was studied in this regard but failed to show significant improvement in AD patients in a phase 3 clinical trial. This was mainly attributed to its low ability to cross the blood–brain barrier (BBB). Here, we present the synthesis and in vitro evaluation of a racemic meta-carborane analogue of flurbiprofen. By introducing the carborane moiety, the hydrophobicity could be shifted into a more favourable range for the penetration of the blood–brain barrier, evident by a logD7.4 value of 2.0. Furthermore, our analogue retained γ-secretase modulator activity in comparison to racemic flurbiprofen in a cell-based assay. These findings demonstrate the potential of carboranes as phenyl mimetics also in AD research.

abstract = "All over the world, societies are facing rapidly aging populations combined with a growing number of patients suffering from Alzheimer’s disease (AD). One focus in pharmaceutical research to address this issue is on the reduction of the longer amyloid-β (Aβ) fragments in the brain by modulation of γ-secretase, a membrane-bound protease. R-Flurbiprofen (tarenflurbil) was studied in this regard but failed to show significant improvement in AD patients in a phase 3 clinical trial. This was mainly attributed to its low ability to cross the blood–brain barrier (BBB). Here, we present the synthesis and in vitro evaluation of a racemic meta-carborane analogue of flurbiprofen. By introducing the carborane moiety, the hydrophobicity could be shifted into a more favourable range for the penetration of the blood–brain barrier, evident by a logD7.4 value of 2.0. Furthermore, our analogue retained γ-secretase modulator activity in comparison to racemic flurbiprofen in a cell-based assay. These findings demonstrate the potential of carboranes as phenyl mimetics also in AD research.",
