A selective inhibitor of hematopoietic prostaglandin D (PGD) synthase, that structurally is a synthetic tetrazole compound originally prepared as a possible antihistamine.1 Subsequent evaluation in models of allergy and asthma demonstrates the HQL-79 is orally available, and inhibits the synthesis of PGD2.2 HQL-79 is thus a likely lead compound for the preparation of potent, selective hematopoietic PGD synthase inhibitors.
