Development of prostaglandin D2 receptor antagonist: discovery of highly potent antagonists
摘要:
The process of discovery for highly potent prostaglandin D-2 (PGD(2)) receptor antagonists is reported. A series of N-(p-alkoxy)benzoyl-2-methylindole-4-acetic acids were synthesized and identified as a new class of selective PGD(2) receptor antagonists. Most of them exhibited strong PGD(2) receptor antagonism in binding studies and the cAMP formation assay. The structure-activity relationships (SAR), including subtype selectivity of the synthesized compounds, are also discussed. (C) 2004 Elsevier Ltd. All rights reserved.
Discovery of orally active prostaglandin D2 receptor antagonists
摘要:
A series of N-(p-alkoxy)benzoyl-2-methylindole-4-acetic acids were synthesized and evaluated for prostaglandin D-2 (DP) receptor affinity and antagonist activity. Some of them exhibited strong receptor binding and were potent in the cAMP formation assays. These antagonists also suppressed allergic inflammatory responses such as the PGD(2)-induced increase of microvascular permeability. Structure-activity relationship (SAR) data are presented.
