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

In Vitro

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].

Cell Viability Assay[2]

Cell Line: HeLa, HCT-116, Hep G2, HL-60, MCF-7, MV4-11 and U2OS
Concentration: 400 or 800 µM
Incubation Time: 5 days
Result: Significantly affected cancer cell survivability.
In Vivo

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].

Animal Model: Female, severe combined immunodeficiency (SCID) mice (bearing HL-60 or MV4-11 cells) [2]
Dosage: 100, 200 and 300 mg/kg
Administration: I.p.; daily for 14 days
Result: Reduced tumor volume by 52.5±9.2% and 55.3±5.7% in HL-60 and MV4–11 injected animals.
