Fifty-seven derivatives of glycyrrhetinic acid (GA) were synthesized, and their anti-hepatitis B virus (HBV) activity was evaluated in HepG 2.2.15 cells. Among them, sixteen compounds showed greater anti-HBV activity than GA, especially, compounds 29, 32, 35, 41 exhibited significantly inhibitory activities against HBV DNA replication with IC50 values of 5.71, 5.36, 8.90 and 9.08 mu M, respectively. The structure-activity relationships (SARs) of GA derivatives were discussed for exploring novel anti-HBV agents. (C) 2012 Elsevier Ltd. All rights reserved.

The butyl ester of 3-oxoglycyrrhetinic acid reacted with semicarbazide in EtOH in the presence of NaOAc to produce the 3-semicarbazone, Hurd–Mori cyclization of which gave in 85% yield a 1,2,3-thiadiazole annelated to ring A.
