A series of 5-chloro-N-aryl-1H-indole-2-carboxamide derivatives were prepared and evaluated as inhibitors of human liver glycogen phosphorylase a (hLGPa). One compound, 5-chloro-N-[4-(1,2-dihydroxyethyl)phenyl]-1H-indole-2-carboxamide (2f), inhibited hLGPa with an IC(50) of 0.90microM. The pyridine analogue of 2f showed inhibitory activity of glucagon-induced glucose output in cultured primary hepatocytes
制备了一系列5-氯-N-芳基-1H-吲哚-2-羧酰胺衍生物,并将其评估为人肝糖原磷酸化酶α(hLGPa)的抑制剂。一种化合物5-氯-N- [4-(1,2-二羟乙基)苯基] -1H-吲哚-2-羧酰胺(2f)抑制hLGPa,IC(50)为0.90microM。2f的吡啶类似物在培养的原代肝细胞中具有胰高血糖素诱导的葡萄糖输出抑制活性,IC(50)为0.62microM,在糖尿病db / db小鼠中具有口服降血糖活性。晶体学测定2f与hLGPa的配合物显示抑制剂在二聚体界面的溶剂腔中结合,两个羟基与hLGPa形成有利的静电相互作用。
