|Description||Chlorprothixene has strong binding affinities to dopamine and histamine receptors, such as D1, D2, D3, D5, H1, 5-HT2, 5-HT6 and 5-HT7, with Ki of 18 nM, 2.96 nM, 4.56 nM, 9 nM, 3.75 nM, 9.4 nM, 3 nM and 5.6 nM, respectively.|
|Features||The first, typical antipsychotic drug of the thioxanthene class to be synthesized.|
Chlorprothixene exerts strong binding affinities to the dopamine and histamine receptors, such as D1, D2, D3, D5 and H1 with Ki values of 18nM, 2.96 nM, 4.56 nM, 9 nM and 3.75 nM, respectively, but has little affinity to H3 (Ki >1000 nM).  Chlorprothixene also shows high affinities for both rat 5-HT6 from stably transfected HEK-293 cells, and rat 5-HT7 receptors from transiently expressed COS-7 cells, with Ki values of 3 nM and 5.6 nM, respectively.  Administration of chlorprothixene results in inhibition of SARS-CoV replication in Vero 76 cells, with IC50 of 16.7 μM for Urbani strain, 13.0 μM for Frankfurt-1, 18.5 μM for CHUK-W1 and 15.8 μM for Toronto-2. There are similar to those detected with promazine 
|In vivo||Chlorprothixene blocks postsynaptic mesolimbic dopaminergic D1 and D2 receptors in the brain depressing the release of hypothalamic and hypophyseal hormones. High dose of chlorprothixene inhibits the protection afforded by iproniazid against the reserpine-induced release of catecholamines in adrenal medulla and brain as well as the decrease of 5HT, NE and DA due to reserpine or iproniazid in rat brain.  Administration of Chlorprothixene restores normal ceramide concentrations in murine bronchial epithelial cells, reduces inflammation in the lungs of mice with cystic fibrosis (CF) and prevents infection with Pseudomonas aeruginosa, by inhibiting acidsphingomyelinase (Asm) and not neutral sphingomyelinase (Nsm). |

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 SDS / 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 SDS / 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.
