    Product Description

    Triacsin C, originally isolated from Streptomyces sp., is an inhibitor of long fatty acid acyl-CoA synthetase (IC50 = 6.3 μM in Raji cells).1 It has been shown to interfere with lipid metabolism by inhibiting the de novo synthesis of triglycerides, diglycerides, and cholesterol esters.2 It is also known to act as a hypotensive vasodilator, modulating endothelial nitric oxide synthase repalmitoylation by limiting palmitoyl CoA availability.3 Triacsin C can inhibit pancreatic β-cell function by suppressing the mobilization of intracellular calcium.4

    WARNING This product is not for human or veterinary use.
