Glycyrrhetinicacid (GA) is one of many interesting triterpenoic acids showing anticancerogenic potential. GA is known to trigger apoptosis in tumour cell lines, although GA has a low cytotoxicity. In our study we were able to prepare derivatives of GA that show lowered the IC50 values as determined by a sulforhodamine B (SRB) assay using 15 different human tumour cell lines. Thus, combining an ester
