- W4285808051 abstract "Herein, the design, synthesis and mechanistic study of five series of imidazo[1,2-a]pyridines 8a-d, 9a-f, 11a-c, 12a-d and 14a-d as anticancer agents were discussed. The cytotoxicity of imidazo[1,2-a]pyridine derivatives was screened against NCI 60 cancer cell lines. The cytotoxicity of compounds 8b, 8c, 9e and 9f was then evaluated against leukemia K-562 cancer cell line and normal lung fibroblasts (WI38). The hydrazone derivatives 8b and 8c exhibited significant cytotoxic activities against the leukemia K-562 cancer cell line with good safety margins (IC50 = 2.91 µM, SI = 8.32 and IC50 = 1.09 µM, SI = 10.54, respectively). In addition, compounds 8b, 8c, 9e and 9f were tested for their EGFR and COX-2 inhibitory activities. The hydrazone derivatives 8b and 8c were the most active EGFR inhibitors with IC50 values of 0.123 and 0.072 µM, respectively. Compound 8c selectively inhibited COX-2 (IC50 = 1.09 µM, SI = 13.78). Moreover, the potential of compound 8c to induce apoptosis in leukemia K-562 cell line was determined. Compound 8c showed a pre-G1 apoptosis and a growth arrest of leukemia K-562 cell line at G1 phase of cell cycle. Also, compound 8c was able to induce caspase-3 overexpression (6.98 folds), if compared to control. Finally, molecular docking studies and physicochemical properties calculation of compounds 8b, 8c, 9e and 9f were carried out to explain the biological data and to predict bioavailability of the most active compounds." @default.
