Used primarily in dermatological research, this compound functions as a selective antagonist of the histamine H4 receptor. It is employed to study inflammatory and pruritic (itch-related) conditions, particularly those involving allergic contact dermatitis and atopic dermatitis. Researchers utilize it to investigate the role of H4 receptors in immune cell signaling and skin inflammation pathways. Due to its ability to modulate itch responses in preclinical models, it has served as a tool compound in the development of new anti-itch therapies. It is not used clinically but supports the discovery and validation of targets for treating chronic skin disorders.
