effective agents against fibrotic diseases. Our compound collection was mined for molecules possessing substructure features associated with S1P2 activity. The weakly potent indole hit 6 evolved into a potent phthalazone series, bearing a carboxylic acid, with the aid of a homology model. Suboptimal pharmacokinetics of a benzimidazole subseries were improved by modifications targeting potential interactions
特发性肺纤维化 (IPF) 是一种慢性进行性肺部疾病。目前的治疗只能减缓疾病进展,使新的治疗策略引人注目。越来越多的证据表明,S1P2 拮抗剂可能是对抗纤维化疾病的有效药物。我们的化合物集合被挖掘为具有与 S1P2 活性相关的亚结构特征的分子。弱效吲哚命中6在同源模型的帮助下,演变成一个有效的酞酮系列,带有一个羧酸。基于扩展清除分类系统 (ECCS) 的概念,通过针对与转运蛋白的潜在相互作用的修饰,改善了苯并咪唑子系列的次优药代动力学。作为化学赋能策略的一部分,脚手架跳跃允许快速探索与羧酸相邻的位置。化合物38具有良好的药代动力学和体外效力,在治疗环境中的三种不同的纤维化疾病体内小鼠模型中以 10 mg/kg BID 有效。
