Isolated from Sarcococca hookeriana, it exhibits antileishmanial and antibacterial activities. It has a role as a metabolite, an antibacterial agent, an antileishmanial agent and an EC 3.1.1.8 (cholinesterase) inhibitor. It is a steroid alkaloid and a tertiary amino compound. It derives from a hydride of a pregnane."}]
