and oxidative metabolic stability. Metabolite identification studies revealed that amide hydrolysis in the D-pocket was the key clearance mechanism for this class. Strategic survey of amide isosteres revealed that carbamates and N-pyrimidines, which maintained exquisite potencies, mitigated the amide hydrolysis issue and led to an improved rat PK profile. The lead compound 28 is a potent IDO1 inhibitor
Indoleamine-2,3-dioxygenase-1 (IDO1) 已成为癌症免疫治疗的一个有吸引力的靶标。自动配体识别系统筛选提供了四氢喹啉类新型 IDO1 抑制剂。效力和药代动力学 (PK) 是此类化合物的关键问题。基于结构的药物设计和极性的策略性结合使得效力、溶解度和氧化代谢稳定性迅速提高。代谢物鉴定研究表明,D 袋中的酰胺水解是此类药物的关键清除机制。对酰胺电子等排体的战略调查显示,氨基甲酸酯和N-嘧啶保持了出色的效力,减轻了酰胺水解问题,并改善了大鼠的 PK 特性。先导化合物28是一种有效的 IDO1 抑制剂,具有干净的脱靶特性,并且具有用于人类的 quaque die 给药潜力。
