A small set of indole-2-carboxamide derivatives identified from a high-throughput screening campaign has been described as a novel, potent, and glucose-sensitive inhibitors of glycogen phosphorylase a (GPa). Among this series of compounds, compound 2 exhibited moderate GP inhibitory activity (IC50 = 0.29 μM), good cellular efficacy (IC50 = 3.24 μM for HepG2 cells and IC50 = 7.15 μM for isolated rat
从高通量筛选活动中鉴定出的一小批吲哚-2-羧酰胺衍生物已被描述为糖原磷酸化酶a(GPa)的新型,有效且对葡萄糖敏感的抑制剂。其中这一系列化合物中,化合物2显示出中度GP的抑制活性(IC 50 = 0.29μM),良好的细胞效力(IC 50 = 3.24μM为HepG2细胞和IC 50 = 7.15μM为分离的大鼠肝细胞),具有良好的吸收一起分布,代谢和消除(ADME)配置文件。在体内动物研究表明,化合物2显著抑制了肾上腺素诱导的糖尿病小鼠中的增加空腹血糖水平。
