Selective iodination and polypeptide composition of pinocytic vesicles
We describe a method for the specific radioiodination of pinocytic vesicles (PVs) based upon the simultaneous endocytosis of lactoperoxidase (LPO) and glucose oxidase (GO). Initial experiments indicated that LPO was interiorized by the macrophage cell line J774 by fluid phase pinocytosis and without detectable binding to the plasma membrane (PM). Interiorization varied linearly with enzyme conc...

Change is not made without inconvenience, even from worse to better. Richard Hooker, as quoted in the preface of Samuel Johnson's A Dictionary of the English Language Oh, so they have internet on computers now! Homer Simpson It is with great pleasure that I announce the rebirth of the former print journal of the Canadian Geriatrics Society as a new online publication, the Canadian Geriatrics Jo...
متن کاملCH-38083, a selective, potent antagonist of alpha-2 adrenoceptors.
The selectivity and specificity of CH-38083 [7,8-(methylenedioxi)-14-alpha-hydroxyalloberbane HCl], a berbane derivative for alpha adrenoceptors has been studied and compared with yohimbine and idazoxan in peripheral tissues and in the central nervous system. In isolated tissue experiments CH-38083 was a competitive antagonist at presynaptic alpha-2 adrenoceptors on the axon terminals of the ra...
متن کاملCatalytic Asymmetric Hydrogenation of Heteroarenes
INTRODUCTION Asymmetric hydrogenation of unsaturated organic compounds has been established as one of the most efficient methods for the preparation of chiral, non-racemic substrates. Among hydrogenation of various substrates, the asymmetric hydrogenation of heteroarenes provides a straightforward approach to a wide range of enantiomerically pure saturated heterocycles, which are subunits of ma...
متن کاملMild and selective base-free C-H arylation of heteroarenes: experiment and computation.
A mild and selective C-H arylation strategy for indoles, benzofurans and benzothiophenes is described. The arylation method engages aryldiazonium salts as arylating reagents in equimolar amounts. The protocol is operationally simple, base free, moisture tolerant and air tolerant. It utilizes low palladium loadings (0.5 to 2.0 mol% Pd), short reaction times, green solvents (EtOAc/2-MeTHF or MeOH...
