Hydroquinone

Synonyms: Quinol, 1,4-Benzenediol, 1,4-Dihydroxybenzene, HQ

Hydroquinone (Quinol, 1,4-Benzenediol, 1,4-Dihydroxybenzene, HQ) is a Melanin Synthesis Inhibitor. The physiologic effect of hydroquinone is by means of Depigmenting Activity. It also posesses antioxidant properties that can cause toxicity in several organs, notably the kidney.This product is a hazardous chemical (acute toxicity/flammable/skin corrosive). Please use it while wearing a protective face mask, gloves, and clothing.

In vitro
In vitro At 50 µM HQ(Hydroquinone), R-28 cells show a significant decrease in cell viability compared with the dimethyl sulfoxide (DMSO)-treated controls. At the 100–500 µM concentrations, all three cell lines show significant cell death (P <0.001). In the ARPE-19, R-28, and HMVEC cultures, the caspase-3/7 activities are not increased at any of the HQ concentration. Neuroretinal R-28 cells are more sensitive to HQ than the ARPE-19 and HMVEC cultures[1].
Cell Research Cell lines ARPE-19, R-28, and HMVEC
Concentrations 500 µM, 200 µM, 100 µM, 50 µM
Incubation Time 24 h
Method

ARPE-19, R-28, and HMVEC are treated for 24 h with four different concentrations of HQ (500 µM, 200 µM, 100 µM, 50 µM). Cell viability, caspase-3/7 activation, DNA laddering patterns, and lactate dehydrogenase (LDH) levels are analyzed.
In Vivo
In vivo In vivo exposure of rats to HQ results in changes of immune response mirrored by impairing allergic lung response to ovalbumin, an antigen unrelated to HQ. HQ exposure impairs the expression of CD45R and CD6 co-stimulatory molecules on activated spleen lymphocytes and diminishes the levels of OA(ovalbumin)-anaphylactic antibodies and the subsequent mast cell degranulation in sensitized rats challenged with OA[2].

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.
