A series of novel pyrazoline-containing derivatives (15-47) has been designed, synthesized and evaluated for their biological activities. Among them, compound 18 displayed the most potent antiproliferative activity against A549, MCF-7 and HepG-2 cells line (IC50 = 0.07 mu M, 0.05 mu M, 0.03 mu M, respectively) and the tubulin polymerization inhibitory activity (IC50 = 1.88 mu M), being comparable to CA-4. Furthermore, we also tested that compound 18 was a potent inducer of apoptosis in HepG-2 cells and it had cellular effects typical for microtubule interacting agents, causing accumulation of cells in the G2/M phase of the cell cycle. These studies, along with molecular docking, provided a new molecular scaffold for the further development of antitumor agents that target tubulin. (C) 2015 Elsevier Masson SAS. All rights reserved.
