12S-HHT (12(S)-HHTrE) is an enzymatic product of prostaglandin H2 (PGH2) derived from cyclooxygenase (COX)-mediated arachidonic acid metabolism. 12S-HHT is an endogenous ligand for BLT2 that fully activates BLT2 in vivo. 12S-HHT suppresses UV-induced IL-6 synthesis in keratinocytes, exerting an anti-inflammatory activity[1][2].

In Vitro	12S-HHT (0-150 nM; 3 hours) has anti-inflammatory activity by attenuating the UVB-induced IL-6 synthesis in HaCaT cells[2]. 12S-HHT inhibits the UVB-stimulated p38 MAPK/NF-κB pathway by up-regulating MKP-1, which leads to the suppression of IL-6 synthesis[2].12S-HHT is an endogenous agonist for BLT2[3]. Western Blot Analysis[2] Cell Line: HaCaT cells Concentration: 0, 12.5, 25, 75 or 150 nM Incubation Time: 3 hours Result: UVB (5 mJ/cm2) irradiation markedly up-regulated IL-6 synthesis and release, which was suppressed by the treatment with 12-HHT in a concentration-dependent manner.
