Product Description

SB271046 (SB 271046; SB-271046; SB-271046A; SB271046A) is a novel, potent, selective and orally bioactive 5-HT6 receptor antagonist with important biological activity. It has 200 times more selectivity than other 5-HT receptor subtypes and inhibits 5-HT6 with a pKi of 8.9. Human 5-HT6 receptors that were recombinantly expressed in HeLa cells in vitro were replaced by SB-271046 with [125I]-SB-258585 and [3H]-LSD. Moreover, [125I]-SB-258585 was transferred by SB-271046 from the rat and pig striatum membranes to the human caudate putamen. In HeLa cells that are stable expression hosts of human 5-HT6 receptors, adenylyl cyclase activity is stimulated by 5-HT alone or in response to increasing concentrations of SB-271046 (10, 30, 100, and 300 nM).

Biological Activity I Assay Protocols (From Reference)
Targets
5-HT6 Receptor ( pKi = 8.92-9.09 )
ln Vitro
In vitro activity :SB 271046 competitively inhibited 5-HT-induced stimulation of adenylyl cyclase activity in functional studies on human 5-HT6 receptors, with a pA2 of 8.71[1].
ln Vivo
SB-271046 results in a minimum effective dose of approximately 0.1 mg/kg p.o. and maximum effect at 4 hours post-dose in the rat maximal electroshock seizure threshold (MEST) test. This rises the seizure threshold over a broad dose range. The blood and brain concentrations of SB 271046 (EC50 of 0.16 μM) and Cmax (0.01-0.04 μM) showed a strong correlation with the achieved level of anticonvulsant activity[1].
Animal Protocol
Male Sprague Dawley rats; Dissolved in 1% methyl cellulose in water; 30 mg/kg; Oral gavage

*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.

Calculator

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
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

Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or 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)
