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].

-
Result:Significantly affected cancer cell survivability.
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].

A slow-releasing donor of hydrogen sulfide inhibits neuronal cell death via anti-PANoptosis in rats with spinal cord ischemia‒reperfusion injury. [Abstract]2024 Jan 12;22(1):33. PMID: 38217003
GYY4137 purchased from MedChemExpress. Usage Cited in: Cell Commun Signal. 2024 Jan 12;22(1):33. [Abstract]
The number of TUNEL-positive neurons was notably increased after SCIRI, which was significantly decreased by GYY4137 treatment (50 mg/kg; IP; 30 min before the onset of spinal cord reperfusion; Single dose).
GYY4137 purchased from MedChemExpress. Usage Cited in: Cell Commun Signal. 2024 Jan 12;22(1):33. [Abstract]
The Western blotting results demonstrated that expression of the p-MLKL, p-RIP1, and p-RIP3 in the SCIRI group were higher than those in the sham group, and the p-MLKL/MLKL, p-RIP1/RIP1, and p-RIP3/RIP3 ratios were increased. With GYY4137 treatment (50 mg/kg; IP; 30 min before the onset of spinal cord reperfusion; Single dose), these changes were largely reversed.
