2D- and 3D-QSAR modelling, molecular docking and <i>in vitro</i> evaluation studies on 18β-glycyrrhetinic acid derivatives against triple-negative breast cancer cell line
identified as important structural features responsible for anticancer activity of MDA-MB-231 inhibitors. Five novel derivatives of glycyrrhetinicacid (GA) named GA-1, GA-2, GA-3, GA-4 and GA-5 were semi-synthesised and screened through the QSAR model. Further, in vitro activities of the derivatives were analysed against human TNBC cell line, MDA-MB-231. The result showed that GA-1 exhibits improved cytotoxic
This study discovered that glycyrrhetinic acid inhibited the human 20S proteasome at 22.3 mu M. 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 IC50 of 0.22 mu M, which was approximately 100-fold more potent than glycyrrhetinic acid.
