Solubility (25°C)* In vitro Ethanol 40 mg/mL (179.92 mM)
DMSO 10 mg/mL (44.98 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%Ethanol 30%PEG300 65%ddH2O
2.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 40 mg/ml clarified Ethanol stock solution to 300 μL of PEG300, mix evenly to clarify it; then continue to add 650 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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).
Targets
SERCA [1]
66.7 μM
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].
