General Description

Hydroquinone monosulfate potassium salt is a chemical compound, often used in scientific and industrial applications. The hydroquinone refers to a component with the properties of a reducing agent, meaning it donates electrons to another substance in chemical reactions. The monosulfate signifies it contains one sulfate group, while potassium salt denotes the potassium ion present. Despite the complexity of the name, the compound itself works to facilitate various chemical reactions, important for different industries like cosmetic, pharmaceutical, and manufacturing. Its exact properties and potential hazards can vary based on the specific substance or context it's being used in.

Urinary excretion of arbutin metabolites after oral administration of bearberry leaf extracts

An HPLC assay with fluorimetric detection of the arbutin metabolites hydroquinone glucuronide (2) and hydroquinone sulphate (6) in urine was developed and validated. Methylarbutin (4) and 6 were synthesised as reference substances. Compound 2 was prepared enzymatically from hydroquinone and uridine 5-diphosphoglucuronic acid using the glucosyltransferase system of rat liver microsomes and enriched by two liquid-liquid and an additional solid phase extraction. Compound 2 as the main component of this purified product was identified by UV and fluorescence spectroscopy, by HPLC-MS, and by enzymatic hydrolysis to hydroquinone (5). The assay yields precise and accurate urine levels of 2, 5 and 6 in the concentration range expected after oral administration of recommended therapeutic doses of bearberry leaf extract. In a preliminary pharmacokinetic study on 3 volunteers the time-dependent renal excretion of arbutin metabolites 2, 5 and 6 was investigated after ingestion of an aqueous bearberry leaf extract containing an arbutin dose recommended by the German Kommission E. More than half of the administered dose of arbutin was excreted within 4 hours mainly in form of the metabolites 2 and 6 and more than 75% of the total applied arbutin was excreted within 24 h. The elimination of 5 was negligible in 2 out of 3 volunteers. The excretion of this metabolite in the third test person reached 5.6% of the total administered arbutin dose. The preliminary pharmacokinetic results confirm that renal elimination of toxicologically critical concentrations of the metabolite 5 will not be expected.

Process for the synthesis of phenoxyalkane derivatives

The invention concerns a process for the synthesis of a compound of formula I STR1 wherein: U and V may be chosen from a range of substituents including hydrogen, halogen, alkyl and alkoxy; R1 and R2 may be chosen from a range of substituents including hydrogen and alkyl; n is 0, 1 or 2; and W may be chosen from a range of substitutents including the group STR2 which may be a free carboxylic acid or derivative thereof; the process comprising reacting a sulfate ester of formula II, wherein Q is a cation, with a compound of formula III, wherein L is a leaving group STR3 and hydrolyzing the sulfate ester formed. Preferably the sulfate ester of formula II is prepared by the oxidation of a phenol of formula IV with a persulfate. STR4
