Publication Open Access Novel 1,2,4-triazoles derived from Ibuprofen: synthesis and in vitro evaluation of their mPGES-1 inhibitory and antiproliferative activity(2022-11-01) BİNGÖL ÖZAKPINAR, ÖZLEM; KULABAŞ, NECLA; TATAR, ESRA; KÜÇÜKGÜZEL, İLKAY; Bulbul B., Ding K., Zhan C., Ciftci G., YELEKÇİ K., Gurboga M., BİNGÖL ÖZAKPINAR Ö., Aydemir E., Baybag D., ŞAHİN F., et al.Some novel triazole-bearing ketone and oxime derivatives were synthesized from Ibuprofen. In vitro cytotoxic activities of all synthesized molecules against five cancer lines (human breast cancer MCF-7, human lung cancer A549, human prostate cancer PC-3, human cervix cancer HeLa, and human chronic myelogenous leukemia K562 cell lines) were evaluated by MTT assay. In addition, mouse embryonic fibroblast cells (NIH/3T3) were also evaluated to determine the selectivity. Compounds 18, 36, and 45 were found to be the most cytotoxic, and their IC50 values were in the range of 17.46-68.76 mu M, against the tested cancer cells. According to the results, compounds 7 and 13 demonstrated good anti-inflammatory activity against the microsomal enzyme prostaglandin E2 synthase-1 (mPGES-1) enzyme at IC50 values of 13.6 and 4.95 mu M. The low cytotoxicity and non-mutagenity of these compounds were found interesting. Also, these compounds significantly prevented tube formation in angiogenesis studies. In conclusion, the anti-inflammatory and angiogenesis inhibitory activities of these compounds without toxicity suggested that they may be promising agents in anti-inflammatory treatment and they may be supportive agents for the cancer treatment.Publication Metadata only Synthesis, molecular modeling, anti-cancer and COX-1/2 inhibitory activities of novel thiazolidinones containing benzothiazole core(2024-01-01) KULABAŞ, NECLA; BİNGÖL ÖZAKPINAR, ÖZLEM; KÜÇÜKGÜZEL, İLKAY; KULABAŞ N., Guven C. T., Duracik M., BİNGÖL ÖZAKPINAR Ö., Kucukguzel I.In this study, new 1,3-thiazolidin-4-one derivatives containing arylmethylene groups in the 5-position were obtained from 6-(trifluoromethoxy)-1,3-benzo-thiazol-2-amine (riluzole). Synthesized compounds were characterized by spectral data and elemental analysis. In vitro, cytotoxic activities of the synthesized molecules were evaluated against the human lung cancer (A549) and human prostate cancer (PC-3) cell lines. Compounds were also tested on mouse embryonic fibroblast cells (NIH/3T3) to determine selectivity. Ten target compounds 3-12 were also screened for their COX-1 and COX-2 inhibitory activities. Of these compounds, 4 showed the highest COX-2 inhibition at 10 μM. Molecular docking calculations were performed to understand the binding interactions of compounds with COX-1 and COX-2 proteins. In silico studies of the tested compounds represented important binding modes that may be responsible for their anti-cancer activity via selective inhibition of the COX-2 enzyme. ADMET predictions were conducted to assess the drug-like properties of the novel compounds.
