A severe age-dependent depletion of reduced glutathione (GSH) occurs in rat forebrain at 1-3 h from intraperitoneal injection of the electrophilic agents cyclohexene-1-one and cycloheptene-1-one. Chronic pretreatment with central dopamine agonists (i.e., ergot alkaloids; particularly, dihydroergocriptine) partially counteracts the GSH

A stirred transfer cell containing equal volumes of light liquid paraffin and an aqueous phase at 37 degrees was used to demonstrate the feasibility of calculating the partition coefficient of an unstable compound by kinetic analysis. Cyclohept-2-enone was chosen since

A series of hydroxy-amide functionalized azolium salts have been designed and synthesized for Cu-catalyzed asymmetric conjugate addition reaction. The (CH(2))(2)-bridged hydroxy-amide functionalized azolium ligand precursors 2, in addition to the previously reported CH(2)-bridged azolium salts 1, have been prepared from

To search for a technique to deplete reduced glutathione (GSH) in brain, the influence of various types of compounds on brain GSH levels was investigated in mice. Of the compounds tested, cyclohexene-1-one, cycloheptene-1-one and diethyl maleate were shown to be
