  4-苯基吡咯烷酮-2-乙酰胺的合成及解痉活性

  摘要：

  众所周知 [i] 各种化合物的解痉特性经常与结构元素的存在有关，这些结构元素包括一个苯基或一个苯环，这些元素相对于一个酰胺基团特别取向，通常是一个片段杂环系统（巴比妥酸、乙内酰脲、吡唑烷二酮、琥珀酰亚胺等）。pyrrolidone-2 的苯基衍生物满足这些要求，事实上，在 5-phenylpyrrolidone-2 的衍生物中发现了具有解痉活性的化合物 [2]。因此，4-苯基吡咯烷酮-2 的衍生物可能显示出明确的解痉作用，正如所指出的，它是苯基替代物 2-吡咯烷酮中在一些其他药理学特性中最活跃的 [3]。

  Inhibition of cyclic adenosine-3',5'-monophosphate phosphodiesterase from vascular smooth muscle by rolipram analogs

  摘要：

  Rolipram [(R,S)-4-[3-(cyclopentyloxy)-4-methoxyphenyl]-2-pyrrolidone] has been shown to inhibit selectively the cAMP phosphodiesterase (PDE) of vascular smooth muscle. In order to further explore the structural requirements for selective PDE inhibition, we synthesized a series of rolipram derivatives differently substituted either at the pyrrolidinone or at the aromatic ring. Among these compounds, rolipram was the most active compound. Semirigid analogues were prepared and used for an evaluation of the active conformation of rolipram. Structural comparison with two other potent and chemically different smooth muscle cAMP-PDE inhibitors, trequinsin and Ro 20-1724, allows us to propose a first topological model of the smooth muscle cAMP-PDE pharmacophore.

• A phase-switch purification approach for the expedient removal of tagged reagents and scavengers following their application in organic synthesis

  DOI：10.1039/b503778f

  日期：——

  In this paper we wish to report on a variety of expedient chemical transformations and purifications achieved via a generic ‘catch and release’ methodology, based on a synthetically inert bipyridyl chelating tag that can be selectively captured with a resin-bound copper(II) species. Utilising this approach we are able to derive many of the same benefits associated with both solid phase synthesis and supported reagent methods.

  本文旨在报道通过一种基于合成不活跃的双吡啶螯合标签的通用“捕获与释放”方法，实现的一系列便捷的化学转化和纯化。该方法可以选择性地利用树脂结合的铜(II)物种来捕获双吡啶螯合标签。采用这种方法，我们能够获得与固相合成和支持试剂法相关的许多相同益处。
