Cerulenin is an epoxy fatty acid amide isolated from the fungus Cephalosporium caerulens and identified as an antifungal in the 1960s. Over the past 40 years cerulenin has found broad application in lipid biochemistry as an inhibitor fatty acid and sterol biosynthesis. Cerulenin binds to B-keto-acyl-ACP synthase blocking the interaction of malonyl CoA. Cerulenin is also an inhibitor of bacterial fatty acid synthesis acting on the FabH, FabB and FabF condensation enzymes. Cerulenin stimulates fatty acid oxidation and inhibits HMG-CoA synthetase activity.
