Abstract: Glycyrrhetinic acid, a facile pentacyclic triterpenoid with rigid and chiral structures, is widely present in the form of aglycone or glycosides in medicinal plants, which is used as bioactive component on anti-inflammatory, anti-viral and anti-tumor-promotion effect. Owing to its relative low-toxicity, biocompatibility and bioactivity, a series of novel opened A-ring and different functional group derivatives of glycyrrhetinic acid was synthesized by chemical methods. The preliminary biological activities were tested against human liver carcinoma(HepG-2) cell in vitro. The results show that the activity should be affected by the number and the position of hydroxyls.

Key words: 18β-Glycyrrhetinic acid, Triterpenoids, Anti-tumor activity
