A series of 1-methyl-1H-indole-pyrazoline hybrids were designed,synthesized,and biologically evaluated as potential tubulin polymerization inhibitors.Among them,compound e19 [5-(5-bromo-1-methyl-1H-indol-3-yl)-3-(3,4,5-trimethoxyphenyl)-4,5-dihydro-1H-pyrazole-1-carboxamide] showed the most potent inhibitory effect on tubulin assembly(IC50=2.12 μM)and in vitro growth inhibitory activity against a panel of four human cancer cell lines(IC50 values of 0.21-0.31 μM).Further studies confirmed that compound e19 can induce HeLa cell apoptosis,cause cell-cycle arrest in G2/M phase,and disrupt the cellular microtubule network.These studies,along with molecular docking and 3D-QSAR modeling,provide an important basis for further optimization of compound e19 as a potential anticancer agent.
