Senicapoc, formerly known as ICA-17043, is a highly potent Gardos Channel (Ca2+-activated K+ channel; KCa3.1) inhibitor/blocker with an IC50 of 11 nM, and with the potential for the treatment of a subset of Hereditary Xerocytosis caused by mutations in the Gardos channel. Senicapoc (ICA-17043) is a potential therapy for the prevention and treatment of hemolysis-associated complications in sickle cell anemia. Senicapoc exhibits Antimalarial Activity.
| ln Vitro |
It was demonstrated that ICA-17043 blocked Gardos channels in mouse (C57 black) RBCs with an IC50 of 50±6 nM. In human red blood cells, ICA-17043 inhibits the rise in cellular hemoglobin concentration in a concentration-dependent way [1].

| ln Vivo |
Following ICA-17043 (10 mg/kg, oral) formulation, there was a significant reduction in gardos channel activity evaluated on days 11 and 21. This reduction was accompanied by an increase in erythrocyte K+ content, but no change in Na+ content. After 11 days of formulation, ICA-17043 (10 mg/kg twice day) significantly increased Hct in SAD mice [1]. Senicapoc (30 mg/kg, face) 48 hours after allergen challenge in sheep decreases eosinophil counts, proliferation, and airway hyperresponsiveness [2].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (7.73 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 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. Solubility in Formulation 2: ≥ 2.5 mg/mL (7.73 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 25.0 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: ≥ 2.5 mg/mL (7.73 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. Solubility in Formulation 4: 2.5 mg/mL (7.73 mM) in 5% DMSO + 40% PEG300 + 5% Tween80 + 50% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a 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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
