polyhydroxyl ring A were synthesized from parental compounds ursolic acid (UA) and oleanolic acid (OA). Here, we showed that most of these derivatives displayed a significantly increased activity against Gram-positive bacteria compared to parental compounds in vitro. Some of these compounds exhibited minimum inhibitory concentration values of 1–3-fold more potent than the positive controls. The structure–activity
