Biological Activity


Targets TRPM8
ln Vitro M8-B (0-100 µM) decreases maximal Ca2+ uptake in a dose-dependent manner, hence inhibiting TRPM8 channel activity [1].
ln Vivo In rats and mice, M8-B (6 mg/kg; iv or ip) lowers deep body temperature[1].
Animal Protocol Animal/Disease Models: Trpm8+/+ rats and mice[1]
Doses: 6 mg/kg
Route of Administration: Iv or ip
Experimental Results: diminished deep body temperature (T(b)) in Trpm8+/+ rats and mice, but not in Trpm8−/− mice.

Solubility Data


Solubility (In Vitro) DMSO: 250 mg/mL (577.42 mM)
Solubility (In Vivo) Solubility in Formulation 1: ≥ 2.08 mg/mL (4.80 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 (4.80 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.

Solubility in Formulation 3: ≥ 2.08 mg/mL (4.80 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 corn oil and mix evenly.

1 mM 2.3097 mL 11.5484 mL 23.0968 mL

10 mM 0.2310 mL 1.1548 mL 2.3097 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.
