  Metaproterenol, Isoproterenol, and Their Bisdimethylcarbamate Derivatives as Human Cholinesterase Inhibitors

  摘要：

  Metaproterenol and isoproterenol are bronchodilators that provide a structural basis for many other bronchodilators currently in use. One of these structurally related bronchodilators is terbutaline; it is administered as a prodrug, bambuterol, and is metabolized (bioconverted) into terbutaline by butyrylcholinesterase (BChE). The metabolism rate can be affected by BChE gene polymorphism in the human population and BChE stereoselectivity. The aim of our study was to investigate inhibition of human BChE and acetylcholinesterase (AChE) with metaproterenol, isoproterenol, and newly synthesized racemic bisdimethylcarbamate derivatives of metaproterenol (metacarb) and isoproterenol (isocarb) and their (R)-enantiomers to see if their bioconversion is affected by BChE inhibition in the same way as that for bambuterol. Metacarb and isocarb proved to be selective BChE inhibitors, as they progressively inhibited AChE 960 to 80 times more slowly than BChE(UU). All studied cholinesterases displayed poor affinity for metaproterenol and isoproterenol, yet BChE(UU) had an affinity about five times higher than that of AChE.

  Synthesis of (R)-bambuterol based on asymmetric reduction of 1-[3,5-bis(dimethylcarbamoyloxy)phenyl]-2-chloroethanone with incubated whole cells of Williopsis californica JCM 3600

  摘要：

  To achieve the synthesis of (R)-bambuterol, a prodrug of (R)-terbutaline, asymmetric reduction of 1-[3,5-bis(dimethylcarbamoyloxy)phenyl]-2-chloroethanone with whole cells of Williopsis californica JCM 3600 pre-incubated on glycerol as a carbon source was examined. Initially, the insolubility of this crystalline substrate (mp 126-127 degrees C) in the incubation broth was an obstacle that needed to be overcome. To solve the problem, the concentration of glycerol was increased to 10% during reduction. Glycerol worked well for recycling oxido-reduction cofactors and for enhancing the water solubility of the substrate. The reduction proceeded smoothly to give enantiomerically pure (R)-alcohol in 81% isolated yield. (C) 2013 Elsevier B.V. All rights reserved.
