摘要:

A series of novel benzothiazole derivatives bearing semicarbazone as a linker was designed and synthesized, and their in vitro antitumor activities were evaluated against four cancer cell lines(HT29, H460, A549 and MDA-MB-231). Most of them showed moderate to excellent activity against all the tested cell lines. Among them, compounds 12a―12i with fluoro-substituted benzyl-1H-indole moiety displayed more potent activity than those with phenyl moiety. The most promising compound 12d exhibited excellent antitumor activity with IC50 values of 0.015, 0.28, 1.53 and 0.68 μmol/L against the four tested cell lines respectively.
