Identification
Common NameCerulenin
ClassSmall Molecule
DescriptionCerulenin is an antifungal antibiotic that inhibits sterol and fatty acid biosynthesis. In fatty acid synthesis, reported to bind in equimolar ratio to b-keto-acyl-ACP synthase. In sterol synthesis, inhibits HMG-CoA synthetase activity. It is also shown to inhibit feeding and induce dramatic weight loss in mice. It is found naturally in the Cephalosporium caerulensfungus.

Toxicity Profile
Route of ExposureNot Available
Mechanism of ToxicityIrreversibly binds to fatty acid synthase, specifically b-ketoacyl-acyl carrier protein synthase (FabH, FabB and FabF condensation enzymes). A number of tumor cells and cell lines have been observed to have highly upregulated expression and activity of fatty acid synthase (FAS). Inhibition of FAS by cerulenin leads to cytotoxicity and apoptosis in human cancer cell lines, an effect believed to be mediated by the accumulation of malonyl-coenzyme A in cells with an upregulated FAS pathway.
MetabolismNot Available
Toxicity ValuesLD50: 547 mg/kg (Oral, Mouse) (1)
