Novel Selective Orally Active CRTH2 Antagonists for Allergic Inflammation Developed from in Silico Derived Hits
摘要:
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.
