| 产品描述 | 3-Oxobetulin is a pentacyclic triterpenoid and derivative of betulinic acid that has been found inI. macropodaand has diverse biological activities.1,2,3It is active against the plant pathogenic fungiL. betulinaandL. sulphureuswhen used at a concentration of 30 µg/ml.23-Oxobetulin reduces HIV-1 replication in MT-2 cells (IC50= 4.1 µM) with a 50% cytotoxic concentration (CC50) value of greater than 100 µM.4It inhibits cadmium-induced cytotoxicity in HepG2 cells in a concentration-dependent manner.3 1.Kim, D.K., Nam, I.Y., Kim, J.W., et al.Pentacyclic triterpenoids from Ilex macropodaArch.
