starting points for the optimization of dissociated GR modulators. To do so, we selected multiple chemical series by structure guided docking studies and evaluated GR agonist activity. From these efforts we identified 5-arylindazole compounds that showed moderate binding to the glucocorticoid receptor (GR) with clear opportunities for further development. Structure guided optimization was used to design
糖皮质激素受体(GR)激动剂作为急性和慢性炎症的最有效治疗方法已使用了半个多世纪,尽管伴随其广泛使用而产生的严重副作用包括葡萄糖耐受不良,肌肉消瘦,皮肤变薄和骨质疏松。作为鉴定具有改进治疗指数的GR配体的起点,我们希望发现与已知GR配体相比具有简化结构的选择性非甾体GR激动剂和拮抗剂,作为优化解离的GR调节剂的起点。为此,我们通过结构指导的对接研究选择了多个化学系列,并评估了GR激动剂的活性。从这些努力中,我们鉴定出了5-芳基吲唑化合物,它们与糖皮质激素受体(GR)具有中等结合力,并具有进一步开发的明显机会。结构指导的优化用于设计可产生有效GR激动剂和拮抗剂的阵列。利用几个体外和体内实验来证明GR激动剂23a(GSK9027)的轮廓类似于经典的甾体GR激动剂。
