17397-89-6 Usage
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.

Uses
Different sources of media describe the Uses of 17397-89-6 differently. You can refer to the following data:
1. 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.

3. 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.
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.

Check Digit Verification of cas no
The CAS Registry Mumber 17397-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,3,9 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17397-89:
(7*1)+(6*7)+(5*3)+(4*9)+(3*7)+(2*8)+(1*9)=146
146 % 10 = 6
So 17397-89-6 is a valid CAS Registry Number.

A concise synthesis of (+)-cerulenin from a chiral oxiranyllithium
Mani, Neelakandha S.,Townsend, Craig A.
, p. 636 - 640 (1997)
(+)-Cerulenin, a potent fungal inactivator of fatty acid synthases, has been prepared in optically pure form by a sequence involving reaction of a chiral oxiranyllithium with (4E,7E)-nonadienal. Synthesis of the former takes advantage of a particularly favorable Sharpless epoxidation and metalation to a configurationally stable organolithium, while the latter is available in quantity by a direct and improved route.
Synthesis of 4-alkyl-4-alkoxybutenolides having unsaturated side chains via chromium carbene complex photochemistry: (+)-cerulenin
Kedar, Tracey E.,Miller, Michael W.,Hegedus, Louis S.

The photochemical reaction between optically active ene carbamates and chromium alkoxycarbene complexes containing unsaturated aliphatic side chains was further developed. Although remote olefinic groups, including conjugated dienes, were tolerated, a homoallylic side chain underwent intramolecular reaction to give a strained cyclobutanone. (+)-Cerulenin was synthesized utilizing the photochemical reaction of an alkynylcarbene complex with an optically active ene carbamate and the bis(π-crotyl)nickel halide alkylation of a vinyl bromide as key steps.
