FKBP12 ligands such as FK506 have been shown to activate the BMP signaling pathway and facilitate tissue regeneration. However, the immunosuppressive activity of FK506 limits its clinical application. Using Heck reaction, we generated nonimmunosuppressive analogs of FK506 by fusing heterocycles to the calcineurin (CN) binding domain of FK506. Structure–activity relationships provided novel mechanistic
已显示FKBP12配体(例如FK506)可激活BMP信号通路并促进组织再生。但是,FK506的免疫抑制活性限制了其临床应用。使用Heck反应,我们通过将杂环融合到FK506的钙调神经磷酸酶(CN)结合域上来生成FK506的非免疫抑制类似物。构效关系为FK506-CN相互作用提供了新颖的机理见解,可用于未来类似物的合理设计。
