The optimisation of the azanaphthyridine series of Spleen Tyrosine Kinase inhibitors is described. The medicinal chemistry strategy was focused on optimising the human whole blood activity whilst achieving a sufficient margin over hERG activity. A good pharmacokinetic profile was achieved by modification of the pKa. Morpholine compound 32 is a potent SYK inhibitor showing moderate selectivity, good
描述了氮酪氨酸吡啶系列脾酪氨酸激酶抑制剂的优化。药物化学策略的重点是优化人类全血活动,同时获得比hERG活动足够的余量。通过修饰pKa获得了良好的药代动力学特征。吗啉化合物32是一种有效的SYK抑制剂,在大鼠Arthus模型中显示出中等的选择性,良好的口服生物利用度和良好的功效,但在Ames分析中显示出了潜在的遗传毒性。
