BMS-309403 | FABP4 inhibitor

BMS-309403 (300657-03-8) is a potent (Ki <2 nM FABP4, Ki = 250 nM FABP3, Ki = 350 nM FABP5) and selective inhibitor of the fatty-acid-binding protein aP2 (FABP4).^1,2 It demonstrated marked reductions in atherosclerotic lesions in an Apoe^-/- mouse model and improved glucose metabolism, reduced inflammation, and increased insulin sensitivity in a Lep^ob/obmouse model. BMS-309403 stimulated glucose uptake in myotubes via activation of AMPK.³ It decreased ER stress-associated inflammation in skeletal muscle⁴ and suppressed inflammation and oxidative stress in mouse and cell models of acute lung injury⁵.
