2,5-Di-t-butyl-1,4-benzohydroquinone (BHQ) has been described as a rather selective sarco-endoplasmic reticulum Ca2+-ATPase (SERCA) inhibitor. However, BHQ is not very specific, as it hits other sites of action besides SERCA. BHQ is shown, in fact, to reduce passive Ca2+ leakage from internal stores of permeabilized A7r5 vascular smooth muscle cells and to inhibit plasma membrane Ca2+ influx in parotid acinar cells, rat thymic lymphocytes, and GH3 pituitary cells. BHQ affects both endothelial and smooth muscle functions in rat aorta rings in vitro. BHQ induces endothelium-dependent relaxation by stimulating the NO synthase pathway, via activation of Ca2+ influx through Ni2+-sensitive Ca2+ channels in the endothelial cells. BHQ exhibits pleiotypic effects on rings deprived of endothelium by inducing both a myotonic response, dependent on the activation of Ca2+ influx via a Ni2+-sensitive pathway, and a myolytic effect, possibly dependent on either the depletion of intracellular Ca2+ stores or antagonism of Ca2+ entry via L-type Ca2+ channels. BHQ is a lipophilic, membrane permeable molecule, capable of generating superoxide anion at both sides of the plasmalemma[1].

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)

*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).

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 )

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.
