GYY 4137

Water-soluble, slow-releasing hydrogen sulfide (H2S) donor. Exhibits vasodilator and antihypertensive activity. Anti-inflammatory. Inhibits LPS-induced release of proinflammatory mediators (IL-1beta, IL-6, TNF-alpha, nitric oxide (NO) and PGE2) and increases the synthesis of the anti-inflammatory chemokine IL-10 through NF-kappaB, ATF-2 and HSP27 dependent pathways. Causes stomatal opening and reduces nitric oxide accumulation in plants. Oxidative stress-induced cell death inhibitor. Shows novel anti-cancer effects in vitro and in vivo. Anti-thrombotic via p-selectin dependent mechanism.
