The molecule is a tetracyclic triterpenoid that is 3,24-dinor-2,4-seco-friedelan-1(10),5,7-triene substituted by methoxycarbonyl groups at positions 2 and 29 and an oxo group at position 4. Isolated from the root bark of Hippocratea excelsa, it exhibits anti-protozoal activity against Giardia intestinalis. It has a role as a metabolite and an antiprotozoal drug. It is a methyl ketone, an enoate ester, a tetracyclic triterpenoid and a methyl ester.
