Ninety-five percent of the cells were in the G1 phase after two days of treatment with KN-93 phosphate. G1 arrest is reversible, and cells peak into the S and G2-M phases one day after KN-93 phosphate is released. KN-93 phosphate also inhibits the proliferation of NIH 3T3 fibroblasts when they are stimulated by platelet-derived growth factor-BB, epidermal growth factor, and basic fibroblast growth factor [1]. While KN-93 phosphate strongly dissipates the proton gradient produced in stomach membrane vesicles and decreases cavity volume, it also inhibits the action of H+ and K+-ATPase [2]. Preventing LV developmental stress rises during action potential extension and early afterdepolarization is possible with KN-93 phosphate (0.5 μM). Early afterdepolarization is characterized by a rise in Ca2+-independent CaM kinase activity, which is inhibited by KN-93 phosphate[3].

Solubility in Formulation 1: ≥ 10 mg/mL (16.69 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 100.0 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. Solubility in Formulation 2: ≥ 10 mg/mL (16.69 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 100.0 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. View More
Solubility in Formulation 3: ≥ 10 mg/mL (16.69 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*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.
