The recent disclosure of type I 1/2 inhibitors for p38α MAPK demonstrated how the stabilization of the R-spine can be used as a strategy to greatly increase the target residence time (TRT) of inhibitors. Herein, for the first time, we describe N-acylhydrazone and selenophene residues as spine motifs, yielding metabolically stable inhibitors with high potency on enzymatic, NanoBRET, and whole blood assays, improved metabolic stability, and prolonged TRT.

N-酰基hydr和硒烯的芳族酰胺连接的脊柱残基的生物立体置换作为一种设计策略，以新颖的二苯并亚砜衍生物作为I 1/2p38αMAP激酶抑制剂。

p38αMAPK的I 1/2型抑制剂的最新披露表明，如何将R脊柱的稳定化用作增加抑制剂的目标停留时间（TRT）的策略。在本文中，我们首次将N-酰基and和硒基残基描述为脊柱基序，产生了对酶，NanoBRET和全血检测具有高效效的代谢稳定抑制剂，改善了代谢稳定性，并延长了TRT。
