investigations of a novel class of triazolopyridazinone p38α mitogen activated protein kinase (MAPK) inhibitors are disclosed. From these studies, increased in vitro potency was observed for 2,6-disubstituted phenyl moieties and N-ethyl triazolopyridazinone cores due to key contacts with Leu108, Ala157 and Val38. Further investigation led to the identification of three compounds, 3g, 3j and 3m that are
公开了新型三唑并吡嗪酮p38α丝裂原活化蛋白激酶(MAPK)抑制剂的结构-活性关系(SAR)研究。从这些研究中,由于与Leu108,Ala157和Val38的关键接触,观察到了2,6-二取代的苯基部分和N-乙基三唑并哒嗪酮核心的体外效力增加。进一步的研究导致鉴定了三种化合物3g,3j和3m,它们是LPS诱导的50%人全血(hWB)中MAPKAP激酶2(MK2)磷酸化的强效抑制剂,并具有理想的体内药代动力学和激酶选择性个人资料。
