carnitine palmitoyltransferase-1

Oxfenicine (4-Hydroxy-L-phenylglycine) is a carnitine palmitoyltransferase-1 inhibitor. Oxfenicine improves whole-body glucose tolerance and insulin sensitivity in high-fat diet-induced obese mouse with insulin resistance.

McN3716 is a carnitine palmitoyltransferase I (CPT-1) inhibitor used for researching metabolic diseases.

Etomoxir sodium salt ((R)-Etomoxir sodium salt) is a carnitine palmitoyltransferase 1a (CPT-1a) inhibitor that inhibits fatty acid oxidation (FAO). Etomoxir sodium salt has antitumor activity.

Teglicar (also known as ST1326) is a selective reversible inhibitor of carnitine palmitoyltransferase 1 (L-CPT1), the liver isoform. It reduces ketogenesis and glucose production, decreases gluconeogenesis, and enhances glucose homeostasis.

Malonyl CoA serves as a substrate in fatty acid biosynthesis while inhibiting fatty acid oxidation. It also acts as a reversible inhibitor of mitochondrial carnitine palmitoyltransferase (CPT) 1 [1] [2].

Carnitine palmitoyltransferase 2 (CPT2), an enzyme involved in fatty acid oxidation, serves as a prognostic biomarker for colorectal cancer (CRC). Overexpression of CPT2 activates phosphorylated p53, enhancing its expression, which in turn suppresses tumor growth and induces apoptosis. Conversely, a deficiency in CPT2 leads to the prevalent hereditary disorder of long-chain fatty acid oxidation in skeletal muscle. Additionally, the downregulation of CPT2 correlates strongly with the advancement of multiple cancers, highlighting its importance in cancer research [1] [2].

4-Hydroxyphenylglyoxylic acid, an active metabolite of the prodrug oxfenicine, functions as an inhibitor of carnitine palmitoyltransferase 1 (CPT1). It effectively inhibits CPT1 in isolated rat liver mitochondria at concentrations of 200 to 1,000 µM and restricts oleate oxidation in isolated rat hepatocytes.

Malonyl CoA tetralithium (Malonyl coenzyme A), serves as a substrate in fatty acid biosynthesis and functions as an inhibitor of fatty acid oxidation. Additionally, it acts as a reversible inhibitor of mitochondrial carnitine palmitoyltransferase (CPT) 1 [1] [2].
