  Dibenzosuberones as p38 Mitogen-Activated Protein Kinase Inhibitors with Low ATP Competitiveness and Outstanding Whole Blood Activity

  摘要：

  p38 alpha mitogen-activated protein (MAP) kinase is a main target in drug research concerning inflammatory diseases. Nevertheless, no inhibitor of p38 alpha MAP kinase has been introduced to the market. This might be attributed to the fact that there is no inhibitor which combines outstanding activity in biological systems and selectivity. Herein an approach to the development of such inhibitors on the basis of the highly selective molecular probe Skepinone-L is described. Introduction of a "deep pocket" moiety addressing the DFG motif led to an increased activity of the compounds. Hydrophilic moieties, addressing the solvent-exposed area adjacent to hydrophilic region II, conserved a high activity of the compounds in a whole blood assay. Combined with their outstanding selectivity and low ATP competitiveness, these inhibitors are very interesting candidates for use in biological systems and in therapy.

  We recently reported 1a (skepinone-L) as a type I p38α MAP kinase inhibitor with high potency and excellent selectivity in vitro and in vivo. However, as a type I inhibitor, it is entirely ATP-competitive and shows just a moderate residence time. Thus, the scope was to develop a new class of advanced compounds maintaining the structural binding features of skepinone-L scaffold like inducing a glycine

  我们最近报告了1a（skepinone-L）作为I型p38αMAP激酶抑制剂，在体外和体内均具有很高的效价和出色的选择性。但是，作为I型抑制剂，它完全具有ATP竞争能力，并且仅显示适度的停留时间。因此，研究范围是开发一种新型的高级化合物，该化合物可维持skepinone-L支架的结构结合特征，例如在铰链区诱导甘氨酸翻转，并同时占据疏水区I和II。用适当的残基扩展该支架会干扰激酶的R-Spine。通过合成69种化合物，我们可以将一个实例的目标停留时间显着延长至3663 s，同时具有出色的选择性得分0.006和出色的效能1.0 nM。通过共结晶验证了这种新的结合模式，1 / 2的结合。此外，微粒体研究显示了最有效的，本文报道的代表的便利的代谢稳定性。

  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

  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。
