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-P
(+)-Pinanediol is an effective inducer of melanogenesis. In S91 cells, it acts by inducing higher levels of pigmentation and synthesis of nitric oxide (NO).

Selective medium-chain free fatty acid receptor GPR84 agonist (EC50 = 139 nM). Exhibits no response at GPR40, GPR41, GPR119 or GPR120 at 100 μM. Activates calcium mobilization, inhibits cAMP accumulation, and induces ERK1/2 phosphorylation, receptor desensitization and internalization in vitro.
