In seeking novel and potent small molecule hematopoietic prostaglandinD2 synthase (H-PGDS) inhibitors as potential therapies for PGD2-mediated diseases and conditions, we explored a series comprising multiple aryl/heteroaryl rings attached in a linear arrangement. Each compound incorporates an amide or imidazole “linker” between the pyrimidine or pyridine “core” ring and the “tail” ring system. We
This invention is directed to a compound of formula (I):
wherein R1, R2 and R3 are as defined herein, a pharmaceutical composition comprising the compound, intermediates and processes for making said compounds, and the use of the compound to treat allergic and/or inflammatory disorders, particularly disorders such as allergic rhinitis, asthma, chronic obstructive pulmonary disease (COPD) and age-related macular degeneration (AMD).
