|Description||SB269970 HCl is a hydrochloride salt form of SB-269970, which is a 5-HT7 receptor antagonist with pKi of 8.3, exhibits >50-fold selectivity against other receptors.|
|Features||A hydrochloride salt form of SB-269970 which is a potent 5-HT 7 receptor antagonist.|
SB-269970 inhibits 5-CT-stimulated adenylyl cyclase activity in guinea-pig hippocampal membranes. SB-269970 (0.03 μM, 0.1 μM, 0.3 μM and 1 μM) produces a concentration-related rightward-shift of the 5-CT concentration-response curve with no significant alteration in the maximal response to 5-CT.  SB-269970 (1 μM) has any effect on 5-HT efflux when superfused alone. 
|In vivo||SB-269970 (10 mg/kg and 30 mg/kg) significantly reduces the effects of amphetamine by 25 and 27%, respectively, and blocks the effects of ketamine by 38% (10 mg/kg) and 30% (30 mg/kg). SB-269970 significantly reduces amphetamine-induced hyperactivity in wild-type mice and is without effects in 5-HT7 knockout mice. Systemic administration of SB-269970 (30 mg/kg) significantly reverses amphetamine disruption of PPI and did not enhance PPI by itself compared to control.  SB-269970 significantly reverses the deficits induced by MK-801, but not by scopolamine. SB-269970 normalizes MK-801-induced glutamate but not dopamine release in the cortex.  SB-269970 (in one medium dose of 0.5 or 1 mg/kg) exerts a specific antianxiety-like effect in the Vogel drinking test in rats, in the elevated plus-maze test in rats and in the four-plate test in mice. Moreover, SB-269970 (in one medium dose of 5 or 10 mg/kg) reveals antidepressant-like activity in the forced swimming and the tail suspension tests in mice.  SB-269970 at doses of 0.3, 1 and 3 μg exhibits an anticonflict effect which is weaker than that of diazepam (40 μg), whereas SB-269970 at doses of 3 and 10 μg had marked anti-immobility action comparable to that of imipramine (0.1 μg). |

|In vitro||DMSO||11 mg/mL (28.28 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
30% propylene glycol, 5% Tween 80, 65% D5W
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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.
