GYY4137 is a slow releasing H2S donor with vasodilator and antihypertensive activity. GYY4137 also exhibits anti-inflammatory and anticancer activity^[1][2][3].

GYY4137 (400-800 µM) causes concentration-dependent killing of seven different human cancer cell lines (HeLa, HCT-116, Hep G2, HL-60, MCF-7, MV4-11 and U2OS) but did not affect survival of normal human lung fibroblasts (IMR90, WI-38)^[2].
GYY4137 (0.1-0.5 mM) decreases LPS-induced production of nitrite (NO2−), PGE2, TNF-α and IL-6 from human synoviocytes (HFLS) and articular chondrocytes (HAC), reduces the levels and catalytic activity of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) and reduced LPS-induced NF-κB activation^[3].

GYY4137 (100-300 mg/kg; i.p.; daily for 14 days) significantly reduces the tumor volume in both animal models, in a dose-dependent manner^[2].
In the complete Freund’s adjuvant (CFA)-treated mouse, GYY4137 (50 mg/kg, i.p.) injected 1 hr prior to CFA increased knee joint swelling while an anti-inflammatory effect, as demonstrated by reduced synovial fluid myeloperoxidase (MPO) and N-acetyl-β-D-glucosaminidase (NAG) activity and decreased TNF-α, IL-1β, IL-6 and IL-8 concentration, was apparent when GYY4137 was injected 6 hrs after CFA^[3].
GYY4137 significantly inhibited tumor growth in the subcutaneous HepG2 xenograft model by inhibiting STAT3 activation and its target gene expression^[4].
GYY4137 prevents nitrative stress and α-synuclein nitration in an MPTP mouse model of parkinson’s disease^[5].
