Abstract

This study discovered that glycyrrhetinic acid inhibited the human 20S proteasome at 22.3microM. Esterification of the C-3 hydroxyl group on glycyrrhetinic acid with various carboxylic acid reagents yielded a series of analogs with marked improved potency. Among the derivatives, glycyrrhetinic acid 3-O-isophthalate (17) was the most potent compound with IC(50) of 0.22microM, which was approximately 100-fold more potent than glycyrrhetinic acid.
