Abstract

Hits from an in silico derived focused library for CRTH2 were transformed into highly selective antagonists with favorable ADME properties. Oral administration of 4-bromo-2-(1-phenyl-1H-pyrazole-4-carbonyl)phenoxyacetic acid (19) inhibited peribronchial eosinophilia and mucus cell hyperplasia in a mouse model of Allergic Asthma, supporting the therapeutic potential of this novel compound class. In addition, this selective pharmacological tool compound provides further evidence for CRTH2 as a relevant therapeutic target for treatment of Th2- and eosinophil-related inflammation.
