New indole amide derivatives as potent CRTH2 receptor antagonists
摘要:
A new series of indole amide acting as hCRTH2 receptor ligands had been explored and are described herein. Several amide derivatives displaying low nanomolar activity in hCRTH2 binding and whole blood assays were identified. They were found to behave as a full antagonists, exhibiting good selectivity over related prostaglandin receptors. Also, prototypical compounds in this novel series which displayed acceptable CYP profiles and were orally bioavailable in rats were identified. (C) 2011 Elsevier Ltd. All rights reserved.
Compound of formula I are antagonists of the PGD2 receptor, CRTH2, and as such are useful in the treatment and/or prevention of CRTH2-mediated diseases such as asthma.
