BMS309403 is specifically designed to target FABP4 with a Ki value less than 2 nM. It is a potent and selective FABP4 inhibitor.[1]

Fatty acid binding proteins (FABPs) are small-molecular weight hydrophobic proteins containing a large hydrophobic cavity, into which naturally occurring long-chain fatty acids and synthetic hydrophobic ligands can be accepted. FABPs act as transporters of endogenous fatty acids from the cell surface to various sites of fatty acid storage and metabolism. In addition to the roles of FABP4 in regulating lipid metabolism and insulin sensitivity, recent pharmacological and biological findings have indicated a regulatory function of FABP4 in inflammation. FABP4 is expressed mainly to macrophages and inflammatory response[1,2]

BMS309403 is an aromatic biphenyl azol compound that competes with fatty acids for the binding pocket of A-FABP with high specificity. BMs30940323 has been shown to lower Mcp-1 secretion from thp-1 macrophages.[3,4]

Chronic administration of BMS309403 (15 mg/kg/day; from 12 to 18 weeks of age) in ApoE-/-mice significantly improved therelaxations, maximal relaxation and EC50 to UK14304, acetylcholine and A23187. Mice orally BMS309403 significantly increased glucose uptake in myotubes in a time and dose dependent manner. Administered with BMS309403 are effectively protected against severe atherosclerosis and type 2 diabetes.[3,4]

BMS-309403 significantly reduced the extent of atherosclerotic lesion area in the proximal aorta in both the early and late intervention studies.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
