  Synthesis of Photoaffinity Probes for Heme-Containing Proteins

  摘要：

  Aryldiazenes with a second, photoactivatable, azide substituent on the aryl ring have been synthesized as active site probes for heme proteins of unknown active site structure. The probes include most of the possible isomers of the phenyl, naphthyl, and biphenyl ring systems. A selection of the probes has been shown to react with the model protein P450(cam) to give (arylazido)iron (FeArN3) complexes, a prerequisite for subsequent affinity labeling of the protein.

  A convenient method for the synthesis of 2-arylazocarboxylates from 2-arylhydrazinecarboxylates by aerobic oxidation with iron phthalocyanine is described. The reaction is applicable to oxidative activation of 1-acyl-2-phenylhydrazines. Some preliminary experiments suggest Michaelis–Menten kinetics and participation of radical species in the reaction mechanism.

  The invention relates to process for the preparation of 2-amino-4-(4- fluorobenzylamino)-l-ethoxycarbonylaminobenzene generically known as Retigabine of the formula (I) and its pharmaceutically acceptable salts e.g. Formula IA, particularly to the modification over the prior art processes-I and II disclosed therein in US5384330. The modifications are depicted in the scheme I and scheme II respectively. Disclosed herein are also the novel processes for the preparation of intermediates of formulae M, N and O of the process-I and of formulae R, S, T of process-II, those are used for preparation of Retigabine of the formula I and its pharmaceutically acceptable salts thereof.

  该发明涉及一种制备2-氨基-4-(4-氟苄胺基)-1-乙氧羰基氨基苯的方法，通常被称为Retigabine，其分子式为(I)，以及其药用可接受盐，例如分子式IA，特别是相对于美国专利US5384330中披露的先前工艺-I和II的改进。这些改进分别在方案I和方案II中描述。本文还披露了制备工艺-I的中间体M、N和O的新工艺，以及工艺-II的中间体R、S、T的分子式，这些中间体用于制备分子式I的Retigabine及其药用可接受盐。
