Drug design efforts led to the synthesis of a series of imidazo[1,2-a]pyridines as adenosine 5′-monophosphate activated protein kinase (AMPK) activators. The most potent compound showed an EC₅₀ value of 11.0 nM against AMPK and significantly reduced ROS levels in high-glucose-induced NRK-49F cells. Western blot experiments demonstrated that this potent compound activates AMPK and affects downstream ACC, decreasing the expression level of TGF-β1.

作为 AMPK 激活剂的咪唑并 [1,2-a] 吡啶衍生物：肾成纤维细胞中活性氧的合成、构效关系和调节

药物设计工作导致合成了一系列咪唑并 [1,2- a ] 吡啶作为腺苷 5'-单磷酸活化蛋白激酶 (AMPK) 激活剂。最有效的化合物对 AMPK 的 EC ₅₀值为 11.0 nM，并显着降低高葡萄糖诱导的 NRK-49F 细胞中的 ROS 水平。Western blot 实验表明，这种有效的化合物可激活 AMPK 并影响下游 ACC，从而降低 TGF-β1 的表达水平。
