Abstract
A new series of 1-naphthyl-5-aryl-1H-1,2,4-triazole-3-carboxamide derivatives were synthesized and structurally proved by 1H and 13C NMR along with high-resolution mass spectrometry. The cytotoxic activity of the newly synthesized compounds was evaluated. Compounds showed a pronounced inhibitory effect against cellular localization of tubulin. Flow cytometric analysis showed that Hep-G2 cells treated indicated a predominated growth arrest at the G2/M-phase compared to that of S-phase. Molecular modeling study using MOE program indicated that most of the target compounds showed good binding with the colchicine-binding site of β-subunit of tubulin with the binding free energy (∆G) values of about 42 kJ/mol.
