BMS309403是一种针对脂肪酸结合蛋白4(FABP4)的联苯唑抑制剂,被认为是有效治疗肥胖相关心脏代谢疾病的先导化合物。在这里,我们发现了BMS309403的脱靶活性,因为它通过AMP活化的蛋白激酶(AMPK)信号传导途径以时间和剂量依赖性方式刺激C2C12肌管中的葡萄糖摄取,但不依赖于FABPs。进一步的分析表明,BMS309403通过增加细胞内AMP:ATP的比例同时降低线粒体膜电位来激活AMPK。这些发现提供了关于BMS 309403作用的机理见解。
BMS309403 is a biphenyl azole inhibitor against fatty acid binding protein 4 (FABP4) and regarded as a lead compound for effective treatment of obesity related cardio-metabolic diseases. Here we discovered an off-target activity of BMS309403 in that it stimulates glucose uptake in C2C12 myotubes in a temporal and dose dependent manner via activation of AMP-activated protein kinase (AMPK) signaling pathway but independent of FABPs. Further analysis indicated that BMS309403 activates AMPK through increasing the ratio of intracellular AMP:ATP while decreasing mitochondrial membrane potential. These findings provide mechanistic insights on the action of BMS309403.
