Özet

In this study, some new thiosemicarbazide and their corresponding 1,3,4-thiadiazole derivatives containing pyridine nuclei were synthesized. Their structures were established based on FT-IR, 1HNMR , 13CNMR , 2D-NMR (HSQC) spectral data and elemental analysis. The MCF-7 and NIH3T3 cells were used to test the compound's anticancer effects. Among the compounds; 4a, 4b, 4d and 4g showed the most potent cytotoxic activity against MCF-7 at IC50 of 3.102 +/- 0.096 mu M, 8.737 +/- 0.103 mu M, 11.190 +/- 0.088 mu M and 12.630 +/- 0.101 mu M, respectively. Their inhibitory activity was assessed against the in vitro aromatase enzyme. Compounds 4a, 4b, 4d and 4g exhibited the promising aromatase inhibition activity with IC50 value of 0.027 +/- 0.002 mu M, 0.068 +/- 0.005 mu M, 1.456 +/- 0.009 mu M and 3.316 +/- 0.001 mu M, respectively (the standard drug letrazole has an IC50 value of 0.023 +/- 0.002 mu M). The molecular docking studies were used to identify the key molecular interactions between the compounds 4a, 4b, 4d and 4g and the aromatase enzyme. Additionally, the physicochemical, druglikeness and pharmacokinetic properties of compounds were also evaluated.
