BTS
Based on 3 publication(s) in Google Scholar
BTS (N-Benzyl-p-toluenesulfonamide) is a potent and selective inhibitor of skeletal muscle myosin II subfragment 1 (S1) ATPase activity, with an IC50s of ~5 µM for actin- and Ca2+-stimulated myosin S1 ATPase. BTS specifically inhibits the contraction of fast skeletal muscle fibers.

IC50: ~5 µM (skeletal muscle myosin II S1 ATPase)
BTS (2-12 μM) inhibits the Ca2+-stimulated ATPase activity of myosin S1 in the absence of actin, with an IC50 of ~5 µM[1].
BTS (2-20 μM) reversibly inhibits the gliding motility rate of heavy meromyosin (HMM)[1].
BTS (100 μM) releases myosin from actin in the presence of ADP[1].
BTS (0-20 μM) reversibly inhibits isometric Ca2+-activated tension in skinned skeletal muscle fibres from rabbit and frog, with IC50s of ~3 µM and 1 µM, respectively[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

DMSO : 125 mg/mL (478.30 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 0.1 mg/mL (0.38 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (9.57 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (9.57 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
