$N$-Acylazole Mediated Stereoselective And Regioselective Synthesis Of $N$-Substituted Azole Acrylonitriles, Osman Aydin, Şule Kökten, Hakan Ünver, İlhami̇ Çeli̇k

Regio- and stereoselective synthesis of $N$-substituted azole acrylonitriles has been achieved smoothly in $N,N$-dimethylformamide (DMF) in the presence of potassium carbonate (K$_{2}$CO$_{3})$ as a base catalyst. $N$-Substituted azole acrylonitriles were obtained in moderate to good yields (39%-87%) with a one-pot reaction between readily available $N$-acetylazoles and Baylis-Hillman nitriles. The structural determinations were accomplished by NOESY $^{1}$H NMR and X-ray crystallography.

In this study, novel 2-substituted benzimidazoles molecules having triazole, thiadiazole, and oxadiazole rings were synthesized and were evaluated by anticancer, antioxidant/oxidant status, genotoxicity, and antiangiogenesis assays. Anticancer activity of the compounds was determined by MTT (0.5, 5, and 50 $\mu $g/mL) and lactate dehydrogenase (LDH) release assays against human prostate and breast cancer cells. Oxidative status of cells was elicited by total oxidative stress and total antioxidant capacity methods. Chick chorioallantoic membrane assay was used to evaluate the antiangiogenic activity. Genotoxicity was evaluated by the sister chromatid exchange (SCE) and micronucleus (MN) tests in lymphocyte cultured human blood. Our results …
