design, synthesis, and biological evaluation of constrained aminopyridinylimidazoles as p38α MAP kinase inhibitors. The frozen analogue approach focused on the pyridinyl unit, using purine bioisosteres as constrained structure analogues. The identification of the most potent bioisostere was followed by a further derivatization to address hydrophobic region II. In combination with C-2 modifications of the
在这项研究中,我们报告了约束性氨基吡啶并咪唑类化合物作为p38αMAP激酶抑制剂的设计,合成和生物学评估。冷冻类似物方法集中于吡啶基单元,使用嘌呤生物等排体作为约束结构类似物。在鉴定出最有效的生物等排体之后,进一步衍生化以解决疏水区域II。结合咪唑核心的C-2修饰,我们能够在p38αMAP激酶上设计高活性抑制剂。本文提出的抑制剂设计代表了这类p38 MAP激酶抑制剂的新近发展阶段的有前途且高效的进展。结合高度灵活的合成策略,指出了进一步研究二芳基咪唑的复杂C-5修饰的方向。
