Product Description
Rheb inhibitor NR1 is a Rheb inhibitor (antagonist) with IC50 of 2.1 μM. Rheb inhibitor NR1 can directly bind to the Rheb switch II domain and selectively inhibit the activation of mTORC1. Rheb inhibitor NR1 inhibits mTORC1-driven phosphorylation of T389pS6K1 and increases phosphorylation of S473pAKT in a dose-dependent fashion. Rheb inhibitor NR1 does not affect mTORC2 activity.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
The size of Jurkat cells is lowered by NR1 (1–10 μM; 48 hours) [1]. MCF-7, TRI102, and PC3 cells are exposed to NR1 (0.37-30 μM) for 90 minutes, which inhibits phosphorylation of T389pS6K1, and promotes phosphorylation of S473pAKT [1]. MCF-7 protein synthesis is decreased by NR1 (1-30 μM; 2.5 h)[1].
ln Vivo
In kidney and skeletal muscle, NR1 (30 mg/kg; i.p.; single dosage) markedly decreased mTORC1 activity and in skeletal muscle, it demonstrated a substantial band shift of T37/464E-BP1 [1].

Solubility Data
Solubility (In Vitro)
DMSO : ~50 mg/mL (~86.46 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.32 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 25.0 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 1.7292 mL 8.6459 mL 17.2918 mL
5 mM 0.3458 mL 1.7292 mL 3.4584 mL
10 mM 0.1729 mL 0.8646 mL 1.7292 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
