Clear solution
5% DMSO 95% Corn oil
3.75mg/ml Taking the 1 mL working solution as an example, add 50 μL of 75 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
3.75mg/ml Taking the 1 mL working solution as an example, add 50 μL of 75 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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.
Targets
STAT3 [2]
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).[4]
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.[3]

Protocol (from reference)

Cell Assay:

[4]
  • 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 The generation of H2S from GYY4137(400 µM) is determined in aliquots (100 µl) withdrawn at timed intervals (up to 7 days) from cultured MCF-7 cells maintained in Dulbecco's modified Eagle's medium.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 Study:

[3]
  • Animal Models

    Complete Freund

  • Dosages

    50 mg/kg

  • Administration
