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.

Rotaviruses are a major cause of acute gastroenteritis in children worldwide. Early stages of rotavirus assembly in infected cells occur in viroplasms. Confocal microscopy demonstrated that viroplasms associate with lipids and proteins (perilipin A, ADRP) characteristic of lipid droplets (LDs).
