A series of hybrids of scopoletin and substituted cinnamic acid were designed, synthesized and evaluated in vitro and in vivo against five human tumor cell lines [MCF-7, MDA-MB-231, A549, HCT-116, and HeLa] with doxorubicin as the positive control. Compounds 17a, 17b, 17c and 17g exhibited potent cytotoxic activity. Especially, compound 17b displayed broad spectrum activity with IC50 values ranging from 0.249 mu M to 0.684 mu M. Moreover, in a preliminary pharmacological study, 17b not only remarkably induced cellular apoptosis, but also clearly induced A549 cells cycle arrest at S phase. In vivo study showed that 17b significantly suppressed tumor growth in a dose-dependent manner without causing the loss of the mean body weight of mice, which was superior to doxorubicin. These preliminary results indicate that 17b is an optimal anti-cancer leading compound and merit further structural modification. (C) 2015 Elsevier Masson SAS. All rights reserved.
