Effects of antagonists on the anti-hyperalgesic effects of sinomenine in CCI rats. * P<0.05 as compared to vehicle control group (N=8 per group). The GABAA receptor antagonist bicuculline but not the opioid receptor antagonist naltrexone nor the 5-HT1A receptor antagonist WAY100635 blocked the antinociceptive effects of 40 mg/kg sinomenine.

Blockade of sinomenine-induced anti-hyperalgesic effects by the GABAA receptor antagonist bicuculline. Filled symbols indicated significant difference in bicuculline-treated and sinomenine-treated group as compared with the sinomenine alone group. n =7-8 male rats per group.

Effects of pretreatment with different receptor antagonists on the anti-hyperalgesic effects of vitexin (10 mg/kg) in mice receiving incisional surgery. Data were expressed as mean ± SEM (n = 10-12 per group), assessed by two-way ANOVA with repeated measures followed by Bonferroni post hoc analysis. Filled black symbols indicated data significantly different from the corresponding vehicle group (P < 0.05).Both the opioid receptor antagonist naltrexone and the GABAA receptor antagonist bicuculline but not the 5-HT1A receptor antagonist WAY100635 completely blocked the anti-hyperalgesic effects of 10 mg/kg vitexin.

|Description||(+)-Bicuculline (d-Bicuculline) is a competitive antagonist of GABAA receptors with IC50 of 2 μM, also blocks Ca(2+)-activated potassium channels.|
(+)-Bicuculline (1-100μM) dose-dependently inhibits the Cl- conductance generated by 40 μM GABA. (+)-Bicuculline also inhibits the agonist action of GABA at 40 μM at α1β2γ2L receptors. (+)-Bicuculline at 1 and 3 μM increases GABA EC50 values 1.6 times (41.0-67.0 μM) and 3.6 times (36.1-129.0 μM), respectively. Atα1β2γ2L GABAA receptors, (+)-bicuculline displays the general property of the competitive antagonist, producing a parallel shift of GABA concentration-effect curves and having no effect on the maximal response of GABA.  In addition to being a potent GABAA receptor antagonist, (+)-bicuculine also blocks Ca2+-activated potassium channels.

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.
