AB  - Clinically-related basic studies on the behavioral effects of ribavirin treatment are still lacking despite its wide use as an antiviral medication. This paper considers the effects of low ribavirin doses (10, 20 and 30 mg/kg/day) on psychomotor activity (novelty-induced exploratory behavior, d-amphetamine (AMPH, 1.5 mg/kg, intraperitoneal)-induced motor activity), and body weight gain in socially undisturbed adult male Wistar rats 24 h after the first, seventh and fourteenth once-a-day injection. Low doses of ribavirin were tested in an attempt to avoid the recognized systemic side effects related to high-dose usage. None of the singly applied ribavirin doses affected exploratory/spontaneous and AMPH-induced motor behavior (locomotion, stereotypy-like and vertical activity), however, body weight gain was significantly lower after treatment with 30 mg/kg of ribavirin. The 7- and 14-day treatments with 10 and 30 mg/kg/day of ribavirin significantly suppressed novelty-induced locomotion and body weight gain; the 14-day treatment with ribavirin at a dose of 30 mg/kg/ day decreased AMPH-induced stereotypy. These findings indicate that repeated application (up to 14 days) of low ribavirin doses results in low novelty-induced locomotion along with reduced weight gain, accentuating the existence of a U-shaped dose-response relationship with a prolonged duration of ribavirin treatment.

AB  - Melanoma, an aggressive skin tumor with high metastatic potential, is associated with high mortality and increasing morbidity. Multiple available chemotherapeutic and immunotherapeutic modalities failed to improve survival in advanced disease, and the search for new agents is ongoing. The aim of this study was to investigate antimelanoma effects of O,O-diethyl-(S,S)-ethylenediamine-N,N'di-2-(3-cyclohexyl) propanoate dihydrochloride (EE), a previously synthesized and characterized organic compound. Mouse melanoma B16 cell viability was assessed using acid phosphatase, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, sulforhodamine B, and lactate dehydrogenase assays. Apoptosis and autophagy were investigated using flow cytometry, fluorescence and electron microscopy, and western blotting. In vivo antitumor potential was assessed in subcutaneous mouse melanoma model after 14 days of treatment with EE. Tumor mass and volume were measured, and RT-PCR was used for investigating the expression of autophagy-related, proapoptotic, and antiapoptotic molecules in tumor tissue. Investigated organic compound exerts significant cytotoxic effect against B16 cells. EE induced apoptosis, as confirmed by phosphatidyl serine externalisation, caspase activation, and ultrastructural features typical for apoptosis seen on fluorescence and electron microscopes. The apoptotic mechanism included prompt disruption of mitochondrial membrane potential and oxidative stress. No autophagy was observed. Antimelanoma action and apoptosis induction were confirmed in vivo, as EE decreased mass and volume of tumors, and increased expression of several proapoptotic genes. EE possesses significant antimelanoma action and causes caspase-dependent apoptosis mediated by mitochondrial damage and reactive oxygen species production. Decrease in tumor growth and increase in expression of proapoptotic genes in tumor tissue suggest that EE warrants further investigation as a candidate agent in treating melanoma.
