CERULENIN Structural

What is CERULENIN?

Description

Cerulenin is a fungal metabolite originally isolated from C. caerulens that has diverse biological activities. It is active against a variety of bacteria, including B. subtilis, E. coli, B. megaterium, and B. anthracis (MICs = 12.5, 12.5, 50, and 50 μg/ml, respectively) and fungi, including strains of C. albicans, T. rubrum, and A. fumigatus (MICs = 0.8-3.7, 3.1-6.2 and 12.5-50 μg/ml, respectively). Cerulenin is an inhibitor of fatty acid synthase type I (FAS-I) and FAS-II (IC50s = 3 and 20 μM, respectively, for the E. coli enzymes). It inhibits fatty acid synthesis in a panel of human cancer cell lines, including breast, ovarian, and endometrial cancer cells, as well as reduces tumor growth in a OVCAR-3 mouse xenograft model.

The Uses of CERULENIN

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 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.

The Uses of CERULENIN

Cerulenin is used as an antifungal antibiotic that inhibits sterol and fatty acids biosynthesis. Cerulenin induces apoptosis in tumor cell lines. It can be a useful biochemical tool with applications for the study of metabolism and function of fatty acids in the bacterial cell membrane and in yeast. An extensive review including the properties, uses, mechanism of action and structure has been reported.

What are the applications of Application

Cerulenin (source Cephalosporium caerulens) is An inhibitor fatty acid and sterol biosynthesis

What are the applications of Application

Cerulenin (synthetic) is a potent and specific antibiotic fatty acid synthase (FAS) inhibitor show to block fatty acid synthesis in microsomes.

Definition

ChEBI: An epoxydodecadienamide isolated from several species, including Acremonium, Acrocylindrum and Helicoceras. It inhibits the biosynthesis of several lipids by interfering with enzyme function.

General Description

An anti-fungal antibiotic that inhibits fatty acid biosynthesis by binding, in equimolar ratio, to β-keto-acyl-ACP synthase. Also inhibits sterol synthesis by blocking the activity of HMG-CoA synthetase activity. Systemic and intracerebroventricular of this compound reduces feeding and induces weight loss.

Biochem/physiol Actions

Primary Targetsterol & fatty acid biosynthesis

Purification Methods

It forms white needles from *C6H6. It has also been purified by repeated chromatography through Florisil and silica gel. It is soluble in EtOH, MeOH, *C6H6, slightly soluble in H2O and pet ether. The dl-form has m 40-42o (from *C6H6/hexane), and the 2R,3S-tetrahydrocerulenin has m 86-87o, [] 20 +44.4 (c 0.25, MeOH after 24hours). [Ohrui & Emato Tetrahedron Lett 2095 1978, Sneda et al.
