|Description||Doxapram HCl inhibits TASK-1, TASK-3, TASK-1/TASK-3 heterodimeric channel function with EC50 of 410 nM, 37 μM, 9 μM, respectively.|
Doxapram inhibits both TASK-1 and TASK-3 function in a dose dependent manner. Doxapram inhibition at both hyperpolarized and depolarized potentials, as well as effects independent of extracellular potassium concentration. It is said that the carboxy terminal domain of TASK-1 is important to doxapram inhibition. Doxapram also inhibits TRESK, TASK-2, and TREK-1 but at significantly larger concentrations (EC50s of 240 μM, 460 μM, and >1 mM, respectively). Doxapram has no effect on MAC for halothane. 
|In vivo||Doxapram is an analeptic agent. The respiratory stimulant action is manifested by an increase in tidal volume associated with a slight increase in respiratory rate. A pressor response may result following Doxapram administration. The mean half-life is 3.4 h (range 2.4-4.1h), the mean apparent volume of distribution is 1.5 mg/kg and the whole body clearance is 370 mL/min. Enteric-coated capsules of doxapram base are absorbed rapidly after an initial delay, and the systemic availability is about 60%.|
|In vitro||DMSO||87 mg/mL (200.93 mM)|
|Water||25 mg/mL (57.73 mM)|
|Ethanol||2 mg/mL (4.61 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
