anticancer agents, eighteen symmetrical biphenyl derivatives structurally related to taspine were synthesized and evaluated in vitro and in vivo. All the compounds were prepared with varied substitutions in the phenyl ring of aniline moiety. The cytotoxicity and anticancer activity of biphenyls was evaluated against various human tumor and normal cell line. Antiproliferative assays indicated that some of them

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.

It has been demonstrated that taspine derivatives act as anticancer agents, thus we designed and synthesized a novel class of symmetrical biphenyl derivatives. We evaluated the cytotoxicity and antitumor activity of biphenyls against five human tumor and normal cell lines. The results indicated that the majority of the compounds exhibited anticancer activity equivalent to or greater than the positive control. Compounds (11) and (12) demonstrated the most potent cytotoxic activity with IC50 values between 19.41 μM and 29.27 μM. The potent antiproliferative capabilities of these compounds against ECV304 human transformed endothelial cells indicated that these biphenyls could potentially serve as antiangiogenic agents. We also reviewed the relationship between structure and activity based on the experimental results. Our findings provide a good starting point for further development of symmetrical biphenyl derivatives as potential novel anticancer agents.
