| Bioactivity | HQL-79, a potent, selective and orally active human hematopoietic prostaglandin D synthase (H-PGDS) inhibitor, highly selectively inhibits the synthesis of PGD2, and acts as an anti-allergic agent, with a Kd of 0.8 μM and an IC50 of 6 μM. Shows no obvious effect on COX-1, COX-2, m-PGES, or L-PGDS[1]. | ||||||||||||
| Target | IC50: 6 μM (H-PGDS)Kd: 0.8 μM (H-PGDS) | ||||||||||||
| Invitro | HQL-79 is a competitive inhibitor against substrate PGH2 and a non-competitive one against GSH[1]. | ||||||||||||
