Synthesis and preliminary biological evaluation of novel taspine derivatives as anticancer agents
摘要:
Antiangiogenic therapy might represent a new promising anticancer therapeutic strategy. Taspine can significantly inhibit cell proliferation of human umbilical vein endothelial cells (HUVECs) induced by vascular endothelial growth factor-165, which is crucial for angiogenesis. In this study, a series of novel taspine derivatives were synthesized and screened for in vitro anticancer and antiangiogenesis activities. The majority of the derivatives demonstrated a moderate degree of cytotoxicity against human cancer cell lines. One of them (14) exhibited much better antiproliferative activity against CACO-2 (IC(50) = 52.5 mu M) and ECV304 (IC(50) = 2.67 mu M) cells than taspine did. Some of them were also effective in antiproliferative assays against HUVECs. The in silico estimate of solubility of title compounds were higher than that of taspine. (C) 2010 Elsevier Masson SAS.

VEGFR-2 plays a critical role in vasculogenesis and inhibitors of VEGFR-2 could be used in the treatment of cancer. Taspine was one of the active ingredients screened by using an endothelial cell membrane chromatography and showed inhibition against VEGFR-2. In our research, we explored how the lactone ring and biphenyl scaffold in taspine influence its potent in vitro anticancer and antiangiogenesis activities. Accordingly, we report the design, synthesis, and preliminary evaluation of four novel taspine derivatives as VEGFR-2 inhibitors. The preliminary biological test showed that one of the compounds showed much better inhibitory activities against CACO-2 (IC50 = 52.5 nM) and ECV304 (IC50 = 2.67 nM) than taspine. This result enlarges the interest in ring-opened taspine derivative skeleton in the search of new antiangiogenesis agents. (C) 2009 Elsevier Ltd. All rights reserved.
