Biological Activity

Description BHQ (2,5-di-t-butyl-1,4-benzohydroquinone) is a potent and selective inhibitor of the sarco-endoplasmic reticulum Ca2+-ATPase (SERCA).

In vitro
In vitro 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].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 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.
