PF-03715455（Cat No.:I008658）is a small-molecule drug candidate developed by Pfizer, known primarily as a potent and selective antagonist of the prostaglandin D₂ receptor 2 (DP2, also known as CRTH2). This receptor plays a key role in inflammatory processes, particularly in allergic and respiratory conditions such as asthma and allergic rhinitis. PF-03715455 inhibits DP2-mediated chemotaxis and cytokine release from Th2 cells, eosinophils, and basophils, helping reduce airway inflammation. Its favorable oral bioavailability and selectivity make it a promising therapeutic agent for modulating immune responses in chronic inflammatory diseases with Th2-skewed pathology.
