Technical Data
GYY 4137 (4-Methoxyphenyl(morpholino)phosphinodithioate morpholinium salt)
Biochemicals Storage: 4°C/-20°CShipping: Blue Ice
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.

Storage and Stability:
Short-term Storage: +4°C
Long-term Storage: -20°C
Stable for at least 2 years after receipt when stored at -20°C. Store solutions at -20°C in the dark.
