Merck, T4540-1MG, Triacsin C from Streptomyces sp.

General description
Triacsin C belongs to a family of fungal metabolites all having an 11-carbon alkenyl chain with a common N-hydroxytriazene moiety at the terminus.
Application
Triacsin C was found to induce maturation in mouse and Xenopus oocytes in the absence of long-chain acyl-CoA synthetase. Triacsin C can also block palmitoylation of the G-protein alpha S subunit⁶. Furthermore, triacsin C can stabilize1-oleoyl-2-acetyl-sn-glycerol (OAG) and enhance perilipin 3 recruitment to the endoplasmic reticulum (ER) in mouse cells⁷.
Biochem/physiol Actions
Triacsin C is a potent inhibitor of long-chain fatty acyl CoA synthetase. It blocks β-cell apoptosis, induced by fatty acids (lipoapoptosis) in a rat model of obesity. In addition, it blocks the de novo synthesis of triglycerides, diglycerides, and cholesterol esters, thus interfering with lipid metabolism.
Preparation Note
Triacsin C is soluble in methanol at 4.90 - 5.10 mg/ml and yields a clear, pale yellow to yellow solution.
