A series of 3-(1H-1,2,3-triazol-1-yl)benzamide derivatives were designed and synthesized as new Bcr-Abl inhibitors by using combinational strategies of bioisosteric replacement, scaffold hopping, and conformational constraint. The compounds displayed significant inhibition against a broad spectrum of Bcr-Abl mutants including the gatekeeper T315I and p-loop mutations, which are associated with disease
利用生物等位取代,支架跳跃和构象约束的组合策略,设计并合成了一系列3-(1 H -1,2,3-三唑-1-基)苯甲酰胺衍生物,作为新的Bcr-Abl抑制剂。这些化合物显示出对广谱的Bcr-Abl突变体(包括网守T315I和p环突变)的显着抑制作用,这些突变与CML中的疾病进展有关。最有效的化合物6q和6qo用IC 50强烈抑制Bcr-Abl WT和Bcr-Abl T315I的激酶活性值分别为0.60、0.36和1.12、0.98 nM。它们还有效抑制K562,KU812人CML细胞以及一组异位表达Bcr-Abl WT或一组其他Bcr-Abl突变体的鼠Ba / F3细胞的增殖,这些突变已被证明有助于临床获得性电阻,包括Bcr-Abl T315I,IC 50值在低纳摩尔范围内。这些化合物可以作为先导化合物,用于进一步开发能够克服临床获得的对伊马替尼的耐药性的新型Bcr-Abl抑制剂。
