The structure–activity relationships of new Aurora A/B kinase inhibitors derived from the previously identified kinase inhibitor 12 are described. Introduction of acetic acid amides onto the pyrazole of compound 12 was postulated to influence Aurora A/B selectivity and improve the profile against off-target kinases. The SAR of the acetic acid amides was explored and the effect of substitution on enzyme
描述了源自先前鉴定的激酶抑制剂12的新型Aurora A / B激酶抑制剂的构效关系。假定将乙酰胺引入化合物12的吡唑中会影响Aurora A / B的选择性并改善针对脱靶激酶的作用。探索了乙酸酰胺的SAR,并研究了取代对酶抑制的影响以及基于机理的细胞活性。另外,筛选了几种更有效的抑制剂的脱靶激酶选择性。
