3-epi Ursolic Acid

3-epi Ursolic acid is a pentacyclic triterpenoid that has been found in M. lingua and has diverse biological activities. It inhibits glycogen phosphorylase and cathepsin L but not cathepsin B (IC50s = 19, 6.5, and >250 µM, respectively). 3-epi Ursolic acid (20-50 µM) inhibits entry of bovine parainfluenza virus 3 into MDBK cells. It also inhibits the proliferation of MCF-7 breast cancer cells (IC50 = 18.6 µg/ml).Formal Name: 3alpha-hydroxy-urs-12-en-28-oic acid. CAS Number: 989-30-0.
