| ln Vitro |
BLU-5937, or camlipixant, at 500 nM, inhibits ATP-mediated DRG neuron sensitization [1].
|
| ln Vivo |
In guinea pigs, the histamine- and ATP-induced allergic cough is lessened by camlipixant (BLU-5937; 3–30 mg/kg; oral)[1]. When compared to control animals, camlipixant (BLU-5937; 10–20 mg/kg; ip) does not change taste perception[1]. Excellent drug-like characteristics of camlipixant (BLU-5937) include outstanding oral bioavailability, low expected human clearance, no penetration of the blood-brain barrier, and a great safety profile[1].

| Animal Protocol |
Animal/Disease Models: Male Dunkin Hartley guinea pigs[1]
Doses: 0.3, 3, 30 mg/kg Route of Administration: PO, approximately 2 h prior to tussive agent exposure Experimental Results: Dramatically decreased the histamine-induced enhancement in the number of citric acid-induced coughs. decreased Dramatically and dose-dependently the ATP-induced enhancement of citric acid-induced coughs. |

Camlipixant is being investigated in the clinical trial NCT05600777 (a 24-week study of the efficacy and safety of BLU-5937 in treating refractory chronic cough in adults (CALM-2)).

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.45 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 (5.45 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 (5.45 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.
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.
