A series of novel compounds carrying 1,2,4-triazole scaffold were prepared and evaluated for their antiproliferative activities against NCI 60 cell line. Compounds 10 (a, c), 11 (a-d), and 14 (a-e) were selected for evaluation at single concentration of 10 mu M towards panel of sixty cancer cell lines. Some of nitric oxide (NO) donating triazole/oxime hybrids 11a-d showed antiproliferative activity better than their corresponding ketones. On the other hand, the thiazolo [3,2-b][1,2,4]-triazoles 14a-e showed remarkable antiproliferative activities against the same cell lines. Compound 14d was selected for five dose testing against the full panel of 60 human tumor cell lines. Compound 14d showed high selectivity against renal subpanel with selectivity ratio of 6.99 at GI(50) level. Compounds 11a-d, 10a-d and 14a-e were tested against four cell lines using MTT assay then compounds of the least IC50 were evaluated against three known anticancer targets including EGFR, BRAF and Tubulin. The results revealed that compound 14d showed promising EGFR inhibitory activity of cancer cell proliferation and were also observed to be moderate BRAF and tubulin inhibitors. Moreover, cell cycle analysis and apoptosis assay were finished for compounds 14d and 14f. Finally molecular modeling studies were performed to explore the binding mode of the most active compounds to the target enzymes. (C) 2018 Elsevier Masson SAS. All rights reserved.
