Resveratrol (3,4,5'-trihydroxy-trans-stilibene) is a famous natural product
which exhibits potential antitumor activity both in vitro and in vivo. In this article, A
series of formamide derivatives of resveratrol (C1-27) were synthesized and their
cytotoxic activities were evaluated, with results indicating that most of the compounds
exhibited antitumor activity against both Smmc7721 and SGC7901 cancer cell lines.
Among them, compound C21 displayed the most potent antitumor activities, with IC50 values of 7.68 and 6.16 M against
Smmc7721 and SGC7901 cancer cell lines respectively. All compounds reported herein were characterized by 1H NMR,
13C NMR, MS and IR spectrum. Additionally, the structure of compound C10 was confirmed by X-ray crystallographic
