Product Description
GSK205 is a highly efficient and selective TRPV4 antagonist (inhibitor) with IC50 of 4.19 μM, which can inhibit TRPV4-mediated Ca2+ influx.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
In 3T3-F442A adipocytes, GSK205 (100 μM) efficiently clamps TRPV4 while simultaneously effectively expanding calcium influx triggered by TRPV4 agonists [1]. Treatment with GSK205 (5 μM; 4 days; T3-F442A adipocytes) increased the expression of genes related to thermogenesis (Mcp1, Mip1α, Mcp3, Rantes, Vcam, etc.) and decreased the expression of pro-inflammatory genes. This modification is similar to the variations in gene expression seen in adipocytes lacking TRPV4[1].
ln Vivo
GSK205 (10 mg/kg; i.p.; twice daily; for 7 days; for 4 weeks; C57BL/6J model) enhances the expression of thermogenic genes, including Pgc1a, Cidea, Cox8b, and Ucp1. In EPI fat, GSK205 led to a decrease in the expression of macrophage markers, pro-inflammatory chemokines, and Tnfa. GSK205 considerably enhances nasal tolerance in mice that undergo diet-induced body weight loss (DIO). Neither a substantial illness nor weight loss was observed [1].
Cell Assay
RT-PCR[1]
Cell Types: T3-F442A adipocytes
Tested Concentrations: 5 μM
Incubation Duration: 4 days
Experimental Results: Genes responsible for thermogenesis Expression is increased and is also accompanied by a decrease in pro-inflammatory gene programs.
Animal Protocol
Animal/Disease Models: Male high-fat diet C57BL/6J mice [1]
Doses: 10 mg/kg
Route of Administration: intraperitoneal (ip) injection; twice a day; 7 days
Experimental Results: Pro-inflammatory chemokines and macrophage markers in fat leading to EPI and diminished expression of Tnfa. Dramatically improves glucose tolerance in diet-induced obese (DIO) mice.

Solubility Data
Solubility (In Vitro)
DMSO : ~250 mg/mL (~519.26 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.32 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.08 mg/mL (4.32 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 2.0771 mL 10.3853 mL 20.7706 mL
5 mM 0.4154 mL 2.0771 mL 4.1541 mL
10 mM 0.2077 mL 1.0385 mL 2.0771 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
