Glaucocalyxin A (GLA) is an active natural tetracyclic diterpenoid isolated from the traditional Chinese herb Isodon glaucocalyx (maxin) Hara. In this work, a series of thiazole type derivatives based on GLA were designed and prepared. Their antiproliferative activities against six tumor cell lines (HepG2, NCI-H460, JEG-3, K562, HL-60 and Hela) were evaluated in-vitro. The results revealed that the introduction of aminothiazole substructures into A-ring of the GLA could improve their antiproliferative effects significantly. Among them,N-alkyl thiazole derivatives showed remarkably activities to the six tumor cell lines. Especially, compounds6and8presented significant antitumor activities against HL-60 and Hela cell lines with IC50 as low as 0.51 µmol•L –1, which were better than the positive drug adriamycin. The apoptosis morphology and flow cytometry studies indicated that the thiazole-fused GLA derivatives could induce apoptosis of tumor cells.
