Product Description
SR-3306 is a potent, brain-permeable/penetrable, selective JNK inhibitor.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Using the MTT assay, the impact of SR-3306 or Tat-Sab on cell viability in response to oxidative stress was determined. When H9c2 cells were treated with 100 μM H2O2/FeSO4, their survival rate was roughly 40%. However, when 500 nM SR-3306 or 500 nM SR3562 were added, the survival rate jumped to almost 90%. Furthermore, cells treated with 100 μM H2O2/FeSO4 had a vitality of 98%; in contrast, cells treated with 10 μM Tat-Sab peptide had a viability of roughly 70%. Primary human cardiomyocytes showed similar outcomes [2].
ln Vivo
When SR-3306 [10 mg/kg/day (sc)] was administered for 14 days, the number of tyrosine hydroxylase immunoreactive (TH+) neurons in the SNpc rose six times after the treatment compared to the control group. decreased striatal TH+ terminal loss. Rats with 6-OHDA lesions on the corresponding side were given vehicle alone (p<0.05). Moreover, SR-3306 [10 mg/kg/day (sc) for 14 days] decreased the cyclic 87% reduction caused by d-amphetamine. At day 14, SR-3306's steady-state brain levels were 347 nM, which is around two times greater than the compound's cell-based IC50. Lastly, SR-3306 [10 mg/kg/day (sc) for 14 days] decreased the number of immunoreactive neurons in the substantia nigra 2.3 times the pars compacta (SNpc) in comparison to rats treated with vehicle, according to immunohistochemistry labeling of phosphorylated c-jun (pc-jun) [1]. SR-3306 administered intraperitoneally (ip) or intracerebroventricularly (icv) decreased food intake and body weight in lean mice. Additionally, SR11935 administered ip or icv had anorexia effects comparable to those of SR3306, indicating that pan-JNK inhibition mediates some of the anorexic effects through JNK2 or JNK3. Moreover, high-fat diet-fed lean mice that get a daily intraperitoneal injection of SR-3306 for seven days are prevented from gaining weight and from eating more, and this injection modality lowers high-fat intake in diet-induced obesity (DIO) and obesity. mice[3].

Solubility Data
Solubility (In Vitro)
DMSO : ~125 mg/mL (~254.81 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.24 mM) (saturation unknown) in 10% DMSO + 40% PEG300 +5% Tween-80 + 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.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 2.0384 mL 10.1922 mL 20.3845 mL
5 mM 0.4077 mL 2.0384 mL 4.0769 mL
10 mM 0.2038 mL 1.0192 mL 2.0384 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
