Oleanolicacid acrylate (OAA) is an agonist of the serotonin (5-HT) receptor subtype 5-HT1A and a derivative of oleanolicacid. It is also a selective inhibitor of MAO-A with anti-depressant-like and anxiolytic activities.
Rehmannic acid and oleanolic acetate inhibit succinoxidase activity. Both Rehmannic acid and Icterogenin are potent uncouplers, abolishing the phosphate uptake, the respiration being inhibited by the former and increased by the latter.
Serratenediol demonstrates strong inhibitory effects on the Epstein-Barr virus early antigen (EBV-EA) activation without showing any cytotoxicity, its effects being stronger than that of a representative control, oleanolicacid. Serratenediol can promote
