An amide library derived from the pyrrolo[2,1-f][1,2,4]triazine scaffold led to the identification of modest inhibitors of Met kinase activity. Introduction of polar side chains at C-6 of the pyrrolotriazine core provided significant improvements in in vitro potency. The amide moiety could be replaced with acylurea and malonamide substituents to give compounds with improved potency in the Met-driven
从吡咯并[2,1-f] [1,2,4]三嗪支架衍生的酰胺库导致鉴定了适度的Met激酶活性抑制剂。在吡咯并三嗪核心的C-6处引入极性侧链可显着提高体外效能。酰胺部分可以被酰基脲和丙二酰胺取代基取代,从而在Met驱动的GTL-16人胃癌细胞系中产生具有增强效价的化合物。在C-5处被取代的酰基脲吡咯并三嗪显示出一位数的纳摩尔激酶活性。X射线晶体学分析表明,C-5取代的吡咯并三嗪以ATP竞争的方式与Met激酶域结合。
