Inflammatory bowel disease, including Crohn's disease and ulcerative colitis, affects millions of people worldwide. CCR9 has been shown to be a key chemokine receptor mediating the local inflammatory responses in the GI tract. The CCR9 inhibitor Vercirnon advanced to phase 3 clinical trials, but carries several liabilities which we sought to improve.
A mild and efficient library synthesis technique has been developed for the synthesis of ureas and carbamates from carbamic acids derived from the DBU-catalyzed reaction of amines and gaseous carbon dioxide. Carbamic acids derived from primary amines reacted with Mitsunobu reagents to generate isocyanates in situ which were condensed with primary and(More)
Irritable bowel diseases (IBD) such as Crohn's disease (CD) and ulcerative colitis (UC) are serious chronic diseases affecting millions of patients worldwide. Studies of human chemokine biology has suggested C-C chemokine receptor 9 (CCR9) may be a key mediator of pro-inflammatory signaling. Discovery of agents that inhibit CCR9 may lead to new therapies(More)
