Biological Activity

Description SB-366791 is a novel, potent, and selective, cinnamide TRPV1 antagonist with an IC50 of 5.7 nM.
TRPV1 [1]
(Cell-based assay)
5.7 nM
In vitro

SB-366791 is a structurally novel and potent TRPV1 antagonist which is capable of inhibiting the capsaicin-, acid- and heat-mediated activation of the receptor but produces little or no effect on a wide range of enzymes, ion channels, GPCRs and other proteins. SB-366791 may prove to be a better tool for unambiguously defining the (patho)physiological role of TRPV1[1].

In vivo the TRPV1 antagonist SB366791 reduces the number of flinches but did not improve ambulation and weight-bearing. A sub-analgesic dose of SB366791 potentiates the effects of morphine at doses of 3.0 and 10.0 mg/kg on flinches and weight-bearing but not ambulation. The combination of morphine and SB366791 has potent analgesic effects on bone cancer pain[2].

Bio Calculators

Molarity Calculator

Molarity Calculator

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)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

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 )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / 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.
