[Abstract]
Objective To design and synthesize glycyrrhetinic acid-matrine complexes, and to evaluate their antitumor activities in vitro. Methods Sophocarpine, 18α-glycyrrhetinic acid and 18β-glycyrrhetinic acid were used as starting materials to synthesize the target compounds glycyrrhetinic acid-matrine complexes by addition, oxidation, and esterification reactions. The antitumor activities in vitro were evaluated by MTT method. Results The target compounds glycyrrhetinic acid-matrine complexes were synthesized and characterized by MS and 1H-NMR. The in vitro antitumor activity experiments showed that the antitumor activity of glycyrrhetinic acid-matrine complexes were higher than those of glycyrrhetinic acid and matrine in vitro, and were better than control drug melphalan. Conclusion The target compounds glycyrrhetinic acid-matrine complexes have good antitumor activities especially against hepatoma cells, which could be a valuable candidate for further development.
