Isolated from Sarcococca hookeriana, it exhibits antileishmanial and antibacterial activities. It has a role as an EC 3.1.1.8 (cholinesterase) inhibitor, an antileishmanial agent, an antibacterial agent and a plant metabolite. It is a steroid alkaloid, a secondary alcohol, an enamide and a secondary carboxamide. It is functionally related to a 3-methylbut-2-enoic acid. It derives from a hydride of a 5alpha-pregnane."}]
