MrgprX2 antagonist-3（Cat No.:I045163）is a potent, selective inhibitor of the Mas-related G protein-coupled receptor X2 (MrgprX2), a key mediator of non-IgE-dependent mast cell activation. By blocking MrgprX2 signaling, it suppresses mast cell degranulation and the release of histamine and pro-inflammatory mediators, thereby reducing pseudo-allergic and drug-induced hypersensitivity reactions. This antagonist serves as an important tool for studying mast cell–driven pathways in allergic, inflammatory, and dermatological disorders. MrgprX2 antagonist-3 shows promise for developing targeted therapies that mitigate pathological immune responses while preserving essential host defense mechanisms.
