Biological Activity

Description GYY4137 is a novel, water-soluble hydrogen sulfide (H2S)–releasing molecule with vasodilator and antihypertensive activity. GYY4137 shows potent anti-hepatocellular carcinoma activity through blocking the STAT3 pathway. GYY4137 also shows anti-inflammatory activity.

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 does not affect survival of normal human lung fibroblasts (IMR90, WI-38).<sup><a class="sref" href="#s_ref">[4]</a></sup>

In vivo

In the complete Freund's adjuvant (CFA)-treated mouse, GYY4137 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, is apparent when GYY4137 was injected 6 hrs after CFA.<sup><a class="sref" href="#s_ref">[3]</a></sup>

Protocol (from reference)

Cell Research:

<sup><a class="sref" href="#s_ref">[4]</a></sup>

  • Cell lines: HeLa, HCT-116, Hep G2, HL-60, MCF-7, MV4-11 and U2OS
  • Concentrations: 400 µM, 800 µM
  • Incubation Time: 5 days, 8 days
  • Method:

    Live cell incubated with GYY4137(400 or 800 µM) are collected after 5 days and counted in triplicate after staining with trypan blue using a haemocytometer for cell viability assay. The generation of H2S from GYY4137(400 µM) is determined in aliquots (100 µl) withdrawn at timed intervals (up to 7 days) from cultured MCF-7 cells maintained in Dulbecco's modified Eagle's medium.

Animal Research:

  • Dosages: 50 mg/kg

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
