Ten new 18β-glycyrrhetinic acid derivatives with dithiocarbamate units were prepared by amidation of 18β-glycyrrhetinic acid and piperazine followed with one-pot condensation of the amide, CS2 and alkyl halides in the presence of potassium carbonate in CHCl3. The structures of all the new compounds were identified by NMR spectra, IR and HRMS technology. Anti-tumor activities of the 18β-glycyrrhetinic acid derivatives against human hepatoma SMMC-7721 cell lines were evaluated by 3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. They were found to inhibit the liver cancer cell proliferation and induce apoptosis as the lowest IC50 value was only 14.42 μg/mL.

Key words: 18β-glycyrrhetinic acid, dithiocarbamates, synthesis, anti-tumor activity
