Abstract

In this paper, a series of novel 4-substituted coumarin derivatives were synthesized. Among these compounds 34, 39, 40, 43, 62, 65, and 67 exhibited significant antiproliferative activity toward a panel of tumor cell lines at subnanomolar IC50 values. Compound 65 showed potent antiproliferative ability (IC50 values of 7-47 nM) and retained full activity in multidrug resistant Cancer cells. Compound 65 caused G2/M phase arrest and interacted with the colchicine-binding site in tubulin, as confirmed by immune-fluorescence staining, microtubule dynamics assays, and competition assays with N,N'-ethylene-bis(iodoacetamide). Compound 65 reduced the cell migration and disrupted capillary-like tube formation in HUVEC cells. Importantly, compound 65 significantly and dose-dependently reduced tumor growth in four xenografts models including paclitaxel sensitive and resistant ovarian tumors (A2780s and A2780/T), adrmicycin sensitive and resistant breast tumors (MCF-7 and MCF-7/ADR), suggesting that compound 65 is a promising novel antimitotic compound for the potential treatment of Cancer.
