be involved in this process. To assess α2B-related pharmacology, we identified a novel α2B antagonist by HTS. The HTS hit showed limited α2A selectivity as well as low solubility and was optimized toward BAY-6096, a potent, selective, and highly water-soluble α2B antagonist. Key aspects of the optimization were the introduction of a permanently charged pyridinium moiety to achieve very good aqueous
急性心肌梗死后,早期再灌注是减少心脏损伤和改善临床结局的最有效策略。然而,恢复缺血心肌的血流可能会自相矛盾地诱发损伤(再灌注损伤),而微血管功能障碍是一个促成因素。α 2B肾上腺素能受体已被假设参与该过程。为了评估 α 2B相关药理学,我们通过 HTS鉴定了一种新型 α 2B拮抗剂。HTS 命中显示出有限的 α 2A选择性以及低溶解度,并针对 BAY-6096 进行了优化,BAY-6096 是一种有效、选择性和高度水溶性的 α 2B对手。优化的关键方面是引入永久带电的吡啶部分以实现非常好的水溶性和酰胺的转化以防止遗传毒性。BAY-6096 剂量依赖性地降低由 α 2B激动剂诱导的大鼠血压升高,证明 α 2B受体在大鼠血管收缩中的作用。
