  Haloarene Derivatives of Carbamazepine with Reduced Bioactivation Liabilities: 2-Monohalo and 2,8-Dihalo Derivatives

  摘要：

  The anticonvulsant carbamazepine 1 is associated with aderse drug reactions (ADRs), including hepatotaxicity; oxidative Metabolism of 1 has been implicated in the pathogenesis of the ADRs. We report the synthesis and evaluation of 2-monohalo and 2,8-dihalo analogues of 1 that were intended to minimize reactive metabolite formation via arene oxidation and 10,11-epoxidation. Halo analogues were obtained either by rearrangement of halogenated N-arylindoles or from specifically halogenated iminodibenzyl derivatives. In rat hepatocytes, none of the :analogues underwent oxidative dehalogenation or glutathiohe adduction. Some formation of the 10,11 epoxide still. occurred, but :aromatic hydroxylation was not seen with the exception of 2-fluoro, which allowed minor monohydroxylation. Complete inhibition of aromatic hydroxylation required at least monochlorination or difluorination of 1. In human liver microsoms, difluoro analogue 5b underwent 10,11-epoxidation but gave no arene oxidation.

  seven-membered 8π azepine was employed as a key core of near-infrared (NIR) dyes. The Janus-faced effect of the thiophene-fused structure, which enhances the antiaromaticity of the azepine ring and, at the same time, relieves the antiaromaticity through the deformation from the aromatic thiophene ring to the quinoidal thienyl moiety, is effective to attain the largely red-shifted absorption and emission

  naturally sought short and efficient methods for our target compounds. In the following report we present an effective two-step synthesis of a range of dibenz[b,f]azepines from appropriate indoles via N-arylation, then acid-catalysed rearrangement, with a critical analysis of other approaches. We showed earlier that this route was effective for fluoro analogues and here present a broader review of its
