Biological Activity

Description Amoxapine (CL 67772) is a tricyclic dibenzoxazepine (an N-aryl piperazine) which acts similarly to several other tricyclic antidepressants, amoxapine inhibits GLYT2a transport activity with IC50 of 92 μM.
GlyT2a [1] GlyT1b [1]
92 μM 1 mM
In vitro

Amoxapine displays a selective inhibition of GLYT2a behaving as a 10 fold more efficient inhibitor of this isoform than of GLYT1b in human embryonic kidney 293 cells. Amoxapine behaves as a competitive inhibitor of both glycine and chloride and a mixed-type inhibitor with respect to sodium. [1] Amoxapine causes acute hERG blockade in oocytes with IC50 of 21.6 mM and in HEK 293 cells with IC50 of 5.1 mM. Amoxapine block is reverse frequency-dependent and causes accelerated and leftward-shifted inactivation. Amoxapine application results in chronic reduction of hERG trafficking into the cell surface membrane with IC50 of 15.3 mM in HEK 293 cells. [2]

In vivo Amoxapine (10 mg/kg i.p., daily) does not affect the levels of dynorphin, substance P and cholecystokinin, but markedly enhances the levels of leu-enkephalin in spinal cord, cerebral cortex and hypothalamus of rats. Amoxapine (10 mg/kg i.p., daily) results in no changes in opioid receptors in the cerebral cortex, but the densities of delta and mu opioid binding sites are increased in the spinal cord, and decreased in the hypothalamus of rats. [3] Amoxapine (1 mg/kg, 5 mg/kg and 10 mg/kg; i.p.) decreases paradoxical sleep and increases deep slow wave sleep especially when it is given at a low dose. Amoxapine (10 mg/kg; i.p.) induces a sustained decrease of paradoxical sleep during the whole treatment, while some tolerance is observed with regard to the inhibitory effect of cericlamine on this state of sleep. [4] Amoxapine decreases locomotor activity, induce ptosis and catalepsy, inhibits apomorphine gnawing and amphetamine stereotyped behavior and by characteristic changes in monkey discriminated avoidance behavior.

Bio Calculators

Molarity Calculator

Molarity Calculator

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 SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

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 )

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.
