Synthesis and α-glucosidase inhibitory activity of oleanolic acid derivatives
摘要:
Glucosidations of oleanolic acid (1) and its dihydroxy-olide derivatives (2) were carried out to provide eight glycosides. All synthesized compounds were evaluated by in vitro -glucosidase inhibitory activity assay. 3-Acetyl dihydroxy-olide oleanolic derivative 15 showed the most potent inhibitory effect. Structure-activity relationships within these compounds are discussed.
