4-[(2-methoxycarbonyl-5-thiophen-2-ylthiophen-3-yl)amino]-4-oxobut-2-enoic acid

개요Adipocyte fatty acid binding protein (A-FABP/aP2) is a carrier protein expressed in both adipocytes and macrophages where it functions in intracellular fatty acid solubilization, trafficking, and metabolism. Molecular disruption of A-FABP/aP2 in mice results in improved insulin sensitivity and protection from atherosclerosis. HTS 01037 is a high-affinity ligand of adipocyte fatty acid binding protein (A-FABP/aP2) (Ki = 0.67 μM) that presumably competes with fatty acids for functional binding in the ligand-binding cavity of A-FABP/aP2. At a concentration of 10 μM, HTS 01037 antagonizes the protein-protein interaction of A-FABP/aP2 with hormone sensitive lipase in cultured C8PA lipocytes. HTS 01037 inhibits lipolysis in 3T3L1 adipocytes and reduces lipopolysaccharide-stimulated inflammation in bone marrow-derived macrophages, both effects of which are similar to the phenotype of A-FABP/aP2 knockout mice.

용도HTS 01037 is an inhibitor of fatty acid binding protein and a competitive antagonist of protein-protein interactions mediated by AFABP/aP2.
