Product Description

BMY 7378 (BMY-7378; BMY7378) is a multi-target compound that inhibits α2C-adrenoceptor and α1D-adrenoceptor with pKi values of 6.54 and 8.2, respectively.

Biological Activity I Assay Protocols (From Reference)

Targets

5-HT1A ( pIC50 = 8.3 ); α1D-adrenoceptor ( pKi = 8.2 ); Dopamine D2 receptor ( pIC50 = 7.4 ); α2C-adrenoceptor ( pKi = 6.54 ); 5-HT1C ( pIC50 = 6.4 )

ln Vitro

In vitro activity: BMY 7378 exhibits selectivity for the alpha 1D-adrenoceptor subtype (pK_i: hamster alpha 1b-adrenoceptor 6.2, human alpha 1b-adrenoceptor 7.2; bovine alpha 1c-adrenoceptor 6.1, human alpha 1c-adrenoceptor 6.6; rat alpha 1d-adrenoceptor 8.2, human alpha 1d-adrenoceptor 9.4) and exhibits a high affinity (pA₂, 8.9) for rat aorta alpha 1-adrenoceptor][2].

ln Vivo

BMY 7378 (pA2 of 8.67) is approximately 100 times more potent than yohimbine (pA2 of 6.62) against contractions to noradrenaline in rat aorta. BMY 7378 (pA2 of 6.48) is approximately 10 times less potent than yohimbine (pA2 of 7.56) at antagonizing the contractile response to noradrenaline in human saphenous vein (α2C-adrenoceptor). BMY 7378 dose dependently (0.25-5 mg/kg s.c.) reduces the undetectable levels forepaw treading and head weaving induced by 8-OH-DPAT (0.75 mg/kg s.c.) in rats. BMY 7378 causes a marked and dose-dependent (0.01-1.0 mg/kg s.c.) decrease of 5-HT release in ventral hippocampus of the anaesthetized rat as detected by brain microdialysis in rats.

Animal Protocol

Dissolved in 0.9% sodium chloride solution; 0.25-5 mg/kg; s.c. injection

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

Calculate the Mass of a compound required to prepare a solution of known volume and concentration
Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?

Enter 350.26 in the Molecular Weight (MW) box
Enter 10 in the Concentration box and choose the correct unit (mM)
Enter 5 in the Volume box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:

Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
Enter 25 into the Concentration (End) box and select the correct unit (mM)
Enter 25 into the Volume (End) box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
