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 -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.
最近公布的 p38α MAPK 的 I 型 1/2 抑制剂表明,如何稳定 R-螺旋可以作为一种策略,极大地增加抑制剂的靶标停留时间(TRT)。在此,我们首次将酰腙和硒吩残基描述为螺旋基序,产生代谢稳定的抑制剂,在酶、NanoBRET 和全血测定中具有高活性,改善了代谢稳定性,并延长了 TRT。
