SCH-23390 is a potent dopamine receptor antagonist (Ki values are 0.2 nM and 0.3 nM at D1 and D5 receptor sub-types, respectively). SCH-23390 is also an agonist at 5-HT1C and 5-HT2C receptors in vitro (Ki values are 6.3 nM and 9.3 nM respectively). It blocks quinpirole-induced Kir3 (GIRK) currents (EC50 = 268 nM) independently of receptors.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
