    Evaluation of cytotoxic, antifungal, and larvicidal activities of different bis-sulfonamide Schiff base compounds
    (Wiley, 2023) Aydin, Hasan; Akocak, Suleyman; Lolak, Nebih; Yumrutas, Onder; Uslu, Ugur; Bozgeyik, Ibrahim; Uckardes, Fatih
    Schiff bases (imines or azomethines) are versatile ligands synthesized from the condensation of amino compounds with active carbonyl groups and used for many pharmaceutical and medicinal applications. In our study, we aimed to determine the cytotoxic, antifungal and larvicidal activities of biologically potent bis-sulfonamide Schiff base derivatives that were re-synthesized by us. For this aim, 16 compounds were re-synthesized and tested for their cytotoxic, antifungal and larvicidal properties. Among this series, compounds A1B2, A1B4, A4B2, A4B3, and A4B4 were shown to have cytotoxic activity against tested cancer lung cell line (A549). The most potent antifungal activity was observed in compounds A2B1 and A2B2 against all fungi. A1B1 showed the strongest larvicidal effect at all concentrations at the 72nd h (100% mortality). These obtained results demonstrate that these type of bis-substituted compounds might be used as biologically potent pharmacophores against different types of diseases.

    Hepatoprotective properties for Salvia cryptantha extract on carbon tetrachloride-induced liver injury
    (C M B Assoc, 2017) Yalcin, Alper; Yumrutas, Onder; Kuloglu, Tuncay; Elibol, Ebru; Parlar, Ali; Yilmaz, Ismet; Pehlivan, Mustafa
    The present study was designed to determine the possible hepatoprotective effects of Salvia cryptantha (black weed) plant extract against carbon tetrachloride (CCl4)-induced hepatic injury in rats. Animals were grouped as follows: control group (Group I), CCl4 group (Group II), olive oil group (Group III), CCl4 + S. cryphantha 200 mg/kg group (Group IV), and CCl4 + S. cryptantha 400 mg/kg group (Group V). Rats were injected intraperitoneally with CCl4 diluted in olive oil (50% v/v) at a dose of 1ml/kg body weight. Bax and Caspase3 were determined by immunohistochemical staining, while apoptotic index was evaluated using TUNEL assay. Total mRNA was isolated from liver tissues, and the levels of BCL2, Caspase3, SOD, CAT, and glutathione peroxidase (GPx) were determined by using PCR, while MDA level were determined using a colorimetric assay. The antioxidant and anti-apoptotic gene transcripts were decreased in all of the control and treatment groups, while Caspase3 levels were not statistically different. The S. cryptantha plant extract treatment was also found to improve SOD, GPx, and catalase levels, while reducing the serum levels of MDA. The extract of S. cryptantha supplementation had a protective effect against CCl4-induced liver damage. S. cryptantha extract as a supplement may be useful as a hepato-protective agent to combat the toxic effects caused by CCl4 and other chemicals.
