摘要
In this study, in order to find novel biologically active penta-1,4-dien-3-one derivatives, a series of penta-1,4-dien-3-one compounds containing a substituted pyrazole subunit were designed and synthesized. Their structures were characterized by H-1-NMR, C-13-NMR and elemental analysis. The preliminary bioassays displayed that most of the title compounds showed significant antiproliferative activity against HepG2 cell lines. Especially, compounds 7a-m, o, r, s, u, w, y and z were active against HepG2 cells with IC50 values of 0.10-5.05 mu M, which were superior to that of the contrast sorafenib (IC50 = 16.20 mu M).
