A pancreatic lipase inhibitor, it is used as an anti-obesity drug. It has a role as an EC 3.1.1.3 (triacylglycerol lipase) inhibitor, a bacterial metabolite, an EC 2.3.1.85 (fatty acid synthase) inhibitor and an anti-obesity agent. It is a beta-lactone, a L-leucine derivative, a member of formamides and a carboxylic ester."}]
