Cerulenin is an epoxy fatty acid amide isolated from the fungus Cephalosporium caerulens 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 is soluble in ethanol, methanol, DMF and DMSO.

    Mechanism of Action

    Cerulenin binds to β-keto-acyl-ACP synthase blocking the interaction of malonyl CoA. Cerulenin also an inhibits bacterial fatty acid synthesis, acting on the FabH, FabB and FabF condensation enzymes. Cerulenin stimulates fatty acid oxidation and inhibits HMG-CoA synthetase activity.
