Description: HQL-79 is a selective and orally active human hematopoietic prostaglandin D synthase (H-PGDS) inhibitor. It inhibits the synthesis of PGD2 and acts as an anti-allergic agent (Kd: 0.8 µM and IC50: 6 µM). It also shows no obvious effect on COX-1, COX-2, m-PGES, or L-PGDS. Target: Others. Smiles:...

HQL-79 is a selective inhibitor of hematopoietic prostaglandin D (PGD) synthase. Structurally, it is a synthetic tetrazole compound originally prepared as a possible antihistamine. Subsequent evaluation in models of allergy and asthma demonstrates the HQL-79 is orally available, and inhibits the synthesis of PGD2...
