Small‐molecule glucose uptake enhancers targeted to myotubes and adipocytes were developed through a phenotypic screening linked with target identification and rational optimization. The target protein of glucose‐uptake enhancers was identified as a nuclear receptor PPARγ (peroxisome proliferator‐activated receptor gamma). Subsequent optimization of initial hits generated lead compounds with high potency
通过与目标识别和合理优化相关联的表型筛选,开发出了针对肌管和脂肪细胞的小分子葡萄糖摄取增强剂。葡萄糖摄取增强剂的目标蛋白被鉴定为核受体PPARγ(过氧化物酶体增殖物激活的受体γ)。初始命中的随后优化产生了对PPARγ反式激活和细胞葡萄糖摄取具有高效力的先导化合物。最后,我们确认优化配体的手性可区分其PPARγ转录活性,结合亲和力和对Cdk5(细胞周期蛋白依赖性激酶5)介导的Ser273处PPARγ磷酸化的抑制活性。结合基于表型的线索发现和早期目标识别,
