ABSTRACT
VEGFR-2 has a pivotal role in promoting cancer angiogenesis. Herein, two series of novel indazole-based derivatives were designed, synthesized and evaluated for their in vitro inhibitory action against VEGFR-2 kinase enzyme. The second series 11a-e exhibited better potency than the first one 7a-d and 8a-f. Compounds 11b, 11c and 11e exhibited the most potent action, with IC50 of 5.4â¯nM, 5.6â¯nM and 7â¯nM, respectively. As a measure of cellular VEGFR-2 inhibition, compounds 11b and 11c showed strong inhibition of human umbilical vein endothelial cells (HUVEC) proliferation with 80% and 99.6% inhibition at 10⯵M concentration, respectively. Attempting to interpret SAR of the synthesized compounds, and provide a basis for further optimization; a comprehensive modeling study was implemented. Molecular docking, dynamics simulation and free energy calculation of the synthesized compounds along with known VEGFR-2 inhibitors were applied. The study illustrated the effect of several factors on VEGFR-2 inhibition, such as the interaction with solvent accessible region of the enzyme, the presence of NH linker and the degree of conformational restriction. Finally, our compounds were evaluated for their in vitro anti-proliferative effect against the full NCI panel of cancer cell lines, where compounds 11a and 11c displayed mean GI% of 93 and 130%, respectively, and showed partly a better behavior than the FDA approved drug sorafenib, with respect to activity (GI50) and safety (LC50) against several cell lines. Thus, compound 11c represents a promising candidate for cancer treatment through antiangiogenic dependent and antiangiogenic independent modes of action.
