Lipogenesis inhibitor is a class of drug that works by inhibiting de novo lipogenesis—the generation of fatty acids in the body. These drugs target enzymes involved in lipogenesis, such as citrate/isocitrate carrier (CIC), ATP-citrate lyase (ACLY), acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS).
Fatty-acyl-CoA synthase, or more commonly known as yeast fatty acid synthase (and not to be confused with long chain fatty acyl-CoA synthetase), is an enzyme complex responsible for fatty acid biosynthesis, and is of Type I Fatty Acid Synthesis (FAS). Yeast fatty acid synthase plays a pivotal role in fatty acid synthesis.
CPT-I inhibitors: etomoxir, oxfenicine, perhexiline CPT-I (carnitine palmitoyl transferase) converts fatty acyl-CoA to fatty acyl-carnitine. Carnitine biosynthesis inhibitor: mildronate [1] 3-KAT inhibitors: trimetazidine 3-KAT (3-ketoacyl-coenzyme A thiolase) inhibitors directly inhibits fatty acid beta-oxidation.
Triacsin C is an inhibitor of long fatty acyl CoA synthetase that has been isolated from Streptomyces aureofaciens. [1] [2] [3] It blocks β-cell apoptosis, induced by fatty acids (lipoapoptosis) in a rat model of obesity.
The latter conversion is mediated by acyl-CoA synthase" acyl-P + HS-CoA → acyl-S-CoA + P i + H + Three types of acyl-CoA synthases are employed, depending on the chain length of the fatty acid. [3] For example, the substrates for medium chain acyl-CoA synthase are 4-11 carbon fatty acids. [4] The enzyme acyl-CoA thioesterase takes of the acyl ...
Control of Acetyl-CoA Carboxylase. The AMP regulated kinase triggers the phosphorylation of the enzyme (thus inactivating it) and the phosphatase enzyme removes the phosphate group. The regulation of mammalian ACC is complex, in order to control two distinct pools of malonyl-CoA that direct either the inhibition of beta oxidation or the ...
Coenzyme A (CoA, SHCoA, CoASH) is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle.All genomes sequenced to date encode enzymes that use coenzyme A as a substrate, and around 4% of cellular enzymes use it (or a thioester) as a substrate.
Acetyl-CoA synthetase (ACS) or Acetate—CoA ligase is an enzyme (EC 6.2.1.1) involved in metabolism of acetate. It is in the ligase class of enzymes, meaning that it catalyzes the formation of a new chemical bond between two large molecules.
