  Possible contribution of a glutathione conjugate to the long-duration action of .beta.-funaltrexamine

  摘要：

  The fumaramate derivative of naltrexone, beta-funaltrexamine (beta-FNA), is a highly selective long-lasting mu opioid receptor antagonist that is active both in vitro and in vivo, presumably as a result of covalent binding to au receptor-based sulfhydryl group. Glutathione, which occurs in significant levels in brain and liver, was found to undergo a Michael-type reaction with beta-FNA in the test tube to give a stable conjugate 3 which occurred as an isomeric mixture. When tested in the GPI and MVD smooth muscle preparations, 3 was found to possess one-tenth the agonist activity of beta-FNA is both tissues, but showed no irreversible antagonist activity. The same result was found for the cysteine conjugate 4, except for some irreversible antagonism in the MVD. Both conjugates antagonize the antinociceptive effect of morphine in the mouse radiant heat tail-flick assay on icv administration. This antagonism persisted and actually increased over 24 h and generally paralleled the duration profile of beta-FNA. On sc administration, beta-FNA and 3 showed similar duration of antagonistic effect, while 4 exhibited only marginal activity at the early time interval. When the compounds are compared by the dose to produce equivalent antagonism, beta-FNA and 3 appeared equally effective and accessible by either route, whereas 4 showed a large difference between the two routes. It is possible that the ultra-long antagonism of the conjugates may result from their enzymatic conversion to beta-FNA in the central nervous system in view of the fact that conjugate 5, which cannot be converted to beta-FNA, did not produce antagonism of long duration in vivo. Alternatively, the protracted antagonism could arise from sequestration of 3 and 4 in tissue compartments that interface with mu opioid receptors.

  N-Bromosuccinimide-dibenzoyl peroxide/azabisisobutyronitrile: a reagent for Z- to E-alkene isomerization

  摘要：

  N-Bromosuccinimide-dibenzoyl peroxide/azobisisobutyronitrile is used to carry out several types of Z- to E-alkene isomerizations. The NBS-bromination conditions are sufficient for both allylic bromination and alkene isomerization. When the allylic hydrogens are not available in substrates, only the isomerization of the alkene takes place. The present conditions for isomerization of carbon-carbon double bonds are mild and efficient. (C) 2003 Elsevier Ltd. All rights reserved.

  Several series of compounds containing the 1,4-dioxo-2-butenyl moiety have been prepared as candidate cytotoxins, including the methyl N-arylmaleamates, methyl N-arylfumaramates, and N-arylmaleimides. In addition, the N-arylisomaleimides were synthesized which are the structural isomers of N-arylmaleimides. These compounds were evaluated against human Molt 4/C8 and CEM T-lymphocytes as well as murine

  nitrogen nucleo­philes to maleimides has been developed for the synthesis of alkyl fumarate derivatives or 3-substituted succinimides, respectively. This reaction system has wide substrate scope and gives moderate to excellent yields (up to 96%) of the desired products. In contrast to the base-catalyzed methods, this strategy is very general, simple, environmentally friendly, and tolerant of oxygen. A practical

  Monosubstituted alkenes RCHCH2 (R = OEt (Ia), SPh (Ib), CO2Me (Ic)) react with phenyl isocyanate on (Lig)Ni0 systems to form tricyclohexylphosphane-5-azanickelacyclopentan-4-one-derivatives (V). It is shown that the complexes V are intermediates in the catalytic CC coupling reaction. Further reactions by the system is dependent upon the nature of R. Thus when R = OEt (Ia) a β-elimination is induced

  can produce pyrano[4,3-c]pyridine-1,5(6H)-diones in high yield (up to 82%) in a single step. The substrates of monoamide fumarates and acetylenes are structurally simple, readily available, and inexpensive. The additive AgSbF6 effectively raised the yields. On account of easier dehydrogenation of OH in the COOH group than NH in the amide group in the reaction, the process first undergoes C–O annulation

  吡喃并[4,3 - c ]吡啶二酮是生物活性化合物和功能材料的关键骨架，通常使用昂贵的底物通过多步合成制备。这项工作表明，Rh(III) 催化的双 C(sp 2 )–H 官能化和单酰胺富马酸酯的 C–O/C–N 环化可以产生吡喃[4,3- c ]吡啶-1,5(6 H ) -单步高产率（高达 82%）的二酮。单酰胺富马酸酯和乙炔的底物结构简单、容易获得且价格低廉。添加剂AgSbF 6有效提高了产量。由于反应中COOH基团中的OH比酰胺基团中的NH更容易脱氢，该过程首先进行C-O环化，然后进行C-N环化。
