Conjugation of phenol by rat liver slices and homogenates.
Numerous contributions have been made to our knowledge of the process of conjugation of phenol in vivo (2, 3). The studies in vitro are related to the formation of either phenyl sulfate (4-6) or glucuronide (7-11). Because of the great difference in behavior towards hydrolysis of the sulfate and the glucuronide (12), the formation of phenyl sulfate and phenyl glucuronide can be followed simulta...
متن کاملSulphate conjugation of p-hydroxytriamterene by platelet phenol sulphotransferase: assay conditions and correlation with metabolism in man.
1 Sulphate conjugation catalyzed by phenol sulphotransferase (PST) is an important pathway in the metabolism of many drugs including triamterene. Variations in PST activity in an easily obtained tissue such as the platelet might reflect individual differences in the sulphate conjugation in other organs and tissues. Human platelets contain at least two forms of PST, a thermolabile (TL) form for ...
متن کاملThe conjugation of phenol, benzoic acid, 1-naphthylacetic acid and sulphadimethoxine in the lion, civet and genet.
In the domestic cat (FeZis catus) phenol is converted mainly to phenylsulphate with only small amounts of phenylglucuronide [l] . The cat’s ability to form the glucuronides of foreign compounds is low compared with other species [2] and it forms little or no glucuronide with phenol [I], benzoic acid [3], sulphadimethoxine [4] , or 1-naphthylacetic acid [5]. It was of interest therefore to find ...
متن کاملOrgano-Iodine(III)-Catalyzed Oxidative Phenol-Arene and Phenol-Phenol Cross-Coupling Reaction.
The direct oxidative coupling reaction has been an attractive tool for environmentally benign chemistry. Reported herein is that the hypervalent iodine catalyzed oxidative metal-free cross-coupling reaction of phenols can be achieved using Oxone as a terminal oxidant in 1,1,1,3,3,3-hexafluoropropan-2-ol (HFIP). This method features a high efficiency and regioselectivity, as well as functional-g...
متن کاملAvalanche phase conjugation.
Image retrieval based on degenerate four-wave mixing with a new nonlinear mechanism is demonstrated. An avalanche nonlinearity associated with induced excited-state absorption is exploited to furnish phase conjugation with threshold behavior and potential motion sensitivity. Population pulsations are reported at high intensities.
