Abstract Four novel N,N-dimethylthiosemicarbazone compounds(1~4) were synthesized by condensation reaction of dehydroepiandrosterone, pregnenolone, estrone, 3,5-dihydroxy-6-formyl-B-norcholestane with N,N-dimethylthiosemicarbazide, respectively, using EtOH(or MeOH) as solvent and HAc as catalyst. The structures were characterized by 1H NMR, 13C NMR, IR and HR-EI-MS. The anti-tumor activities of 1~4 against human hepatoma cells(HepG), nasopharyngeal carcinoma cells(CNE-2) and normal kidney epithelial cells(HEK293T) were investigated by MTT method. The results showed that 1~3 had better antiproliferative activities against HepG and CNE-2.
