General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Dopamine receptor pharmacology.[Pubmed:7940991]

Trends Pharmacol Sci. 1994 Jul;15(7):264-70.

Dopamine receptors are the primary targets in the treatment of schizophrenia, Parkinson's disease, and Huntington's chorea, and are discussed in this review by Philip Seeman and Hubert Van Tol. Improved therapy may be obtained by drugs that selectively target a particular subtype of dopamine receptor. Most antipsychotic drugs block D2 receptors in direct correlation to clinical potency, except clozapine, which prefers D4 receptors. D1 and D2 receptors can enhance each other's actions, possibly through subunits of the G proteins. In schizophrenia, the D2 and D3 receptor density is elevated by 10%, while the D4 receptor density is elevated by 600%. Therefore, D4 receptors may be a target for future antipsychotic drugs. While antipsychotics originally helped to discover dopamine receptors, the five cloned dopamine receptors are now facilitating the discovery of selective antipsychotic and antiparkinson drugs.

Dopamine D4 receptors bind inactive (+)-aporphines, suggesting neuroleptic role. Sulpiride not stereoselective.[Pubmed:8097160]

Eur J Pharmacol. 1993 Mar 16;233(1):173-4.

In order to identify new atypical antipsychotic drugs which are more selective for the human dopamine D4 receptor than for the human dopamine D2 (long) receptor, we tested enantiomer pairs of dopamine agonists and dopamine antagonists on the expressed proteins of these cloned receptors. The (+)-aporphines ((+)-N-propyl-norapomorphine, 11-OH-N-propyl-norapomorphine and (+)-apomorphine) bound to the dopamine D4 receptor with selectivities up to 20 times greater than to the dopamine D2 receptor, suggesting that these pharmacologically inactive enantiomers may succeed as atypical neuroleptics.

Description

Sulpiride is a D2 receptor a antagonist, an atypical antipsychotic drug of the benzamide class, used mainly in the treatment of psychosis associated with schizophrenia and major depressive disorder, and sometimes used in low dosage to treat anxiety and mild depression.
