In our continuing efforts to explore structure–activity relationships around the novel class of potent, isonicotinamide-based GSK3 inhibitors described in our previous report, we extensively explored structural variations around both 4/5-pyridine substitutions and the amide group. Some analogs were found to have greatly improved pTau lowering potency while retaining high kinase selectivity. In contrast
在我们不断努力探索我们之前报告中描述的新型强效异烟酰胺类 GSK3 抑制剂的结构-活性关系的过程中,我们广泛探索了 4/5-吡啶取代和酰胺基团的结构变异。一些类似物被发现具有大大提高的 pTau 降低效力,同时保持高激酶选择性。与之前的活性化合物1a-c相比,相近的类似物3h在三重转基因小鼠阿尔茨海默氏病模型中未显示体内功效。一般来说,这些 2-吡啶基酰胺衍生物在小鼠血浆中容易发生酰胺酶介导的水解。
