|Description||Maprotiline HCl is a selective noradrenalin re-uptake inhibitor, used in the treatment of depression.|
Maprotiline inhibits HERG channels expressed in HEK cells with an IC50 of 5.2 μM and HERG channels expressed in oocytes with an IC50 of 24 μM. Maprotiline blocks open channels but has no significant effect on closed channels.  Maprotiline is atetracyclic antidepressant, which strongly inhibits the uptake of noradrenaline, though it is notable in its lack of inhibition of serotonergic uptake. Maprotiline also has markedly less pronounced alpha-adrenergic blocking activity than amitriptyline.  Maprotiline decreases cell viability in a concentration- and time-dependent manner in Neuro-2a cells. Maprotiline induces apoptosis and increases caspase-3 activation. Maprotiline also induces [Ca(2+)](i) increases which involves the mobilization of intracellular Ca(2+) stored in the endoplasmic reticulum. 
|In vivo||Maprotiline results in significantly increases GluR1 and GluR2/3 subunit expression in the nucleus accumbens and dorsal striatum of mice as detected by immunohistochemistry; and significantly increases GluR1 and GluR2/3 expression in the hippocampus, as demonstrated by Western blot analysis.  Maprotiline has a potent anti-inflammatory effect in rats and this effect is linked to the peripheral and supraspinal actions of the drug.  Maprotiline impairs learning when administered before training, but no statistically significant effect is evident when administered after training. |

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.
