摘要:
Irritable bowel diseases (IBD) such as Crohn's disease (CD) and ulcerative colitis (UC) are serious chronic diseases affecting millions of patients worldwide.

Discovery of agents that inhibit CCR9 may lead to new therapies for CD and UC patients. Herein we describe the evolution of a high content screening hit (1) into potent inhibitors of CCR9, such as azaindole 12. (C) 2016 Elsevier Ltd. All rights reserved.
