lead series of p38 mitogen-activated protein kinase inhibitors using a structure-based design strategy from high-throughput screening of hit compound 1. X-ray crystallography of 1 with the kinase showed an infrequent flip of the peptide bond between Met109 and Gly110, which was considered to lead to high kinase selectivity. Our structure-based design strategy was to conduct scaffold transformation of
我们从高通量筛选命中化合物1的过程中,采用基于结构的设计策略,鉴定了一系列先导性p38促丝裂原活化蛋白激酶抑制剂。X射线晶体学分析表明,该激酶1的Met109和Met109之间的肽键很少翻转Gly110,被认为可导致高激酶选择性。我们基于结构的设计策略是进行1的支架转化,并维持与酶的翻转铰链骨架的氢键相互作用。按照这种策略,我们专注于支架转化,以鉴定咪唑并[4,5-b]吡啶-2-酮衍生物作为p38 MAP激酶的有效抑制剂。在评估的化合物中,发现21种是p38 MAP激酶的有效抑制剂,脂多糖诱导的人单核细胞白血病细胞中的肿瘤坏死因子-α(TNF-α)的产生,以及TNF-α诱导的人全血细胞中白细胞介素8的产生。在这里,我们描述了一种有效的和口服生物可用的咪唑并[4,5-b]吡啶-2-二酮基的p38 MAP激酶抑制剂的发现,该抑制剂可抑制基于人全血细胞的测定中细胞因子的产生。
