Abstract:

Aiming to develop novel candidates for antitumor drugs, sixteen monocarbonyl curcumin derivatives were constructed by dexterously intergrating a coumarin fragment into the penta-1,4-dien-3-one skeleton deriving from the structural optimization of a curcumin molecule. After structural confirmations, the above derivatives were tested by a methyl thiazolyl tetrazolium(MTT) colorimetric assay for their inhibitory activities against the in vitro proliferation of gastric cancer cells(SGC7901) and hepatoma carcinoma cells(HepG2). The bioassay results demonstrated that most of synthesized molecules exhibited outstanding inhibitory effects against the in vitro proliferation of SGC7901 and HepG2 cells. Strikingly, the half maximal inhibitory concentrations(IC50) of compounds 4c and 4j against SGC7901 cells reached 0.22 and 0.27 µmol/L, respectively, which are obviously better than that of epirubicin(1.23 µmol/L). Meanwhile, the IC50 value of compounds 4l against HepG2 cells reached 0.47 µmol/L that is observably superior to that of epirubicin(2.30 µmol/L). Subsequently, morphological observations reconfirmed the outstanding advantage of coumarin-containing penta-1,4-dien-3-ones on inhibiting the in vitro proliferation of tumor cells, which implied these distinctive derivatives could be further developed as novel candidates for antitumor drugs.
