Design, synthesis, and biological evaluation of the N-diarylalkenyl-piperidinecarboxylic acid derivatives as GABA uptake inhibitors (I)
摘要:
Twenty novel N-diarylalkenyl-piperidinecarboxylic acid derivatives were synthesized and evaluated as gamma-aminobutyric acid uptake inhibitors. The biological assay showed that (R)-1-[4,4-bis(3-phenoxymethyl-2-thienyl)-3-butenyl]-3-piperidinecarboxylic hydrochloride (4e) possessed almost as strong GAT1 inhibitory activity as tiagabine. The synthesis and structure-activity relationships are discussed. (c) 2005 Elsevier Ltd. All rights reserved.

[EN] The present invention relates to novel N-substituted azaheterocyclic carboxylic acids and esters thereof in which a substituted alkyl chain forms part of the N-substituent or salts thereof, to methods for their preparation, to compositions containing them, and to their use for the clinical treatment of painful, hyperalgesic and/or inflammatory conditions in which C-fibers play a pathophysiological role by eliciting neurogenic pain or inflammation. [FR] Composé de formule (I) dans laquelle Z est sélectionné parmi les groupes de la formule (II). L'invention porte sur de nouveaux acides carboxyliques azahétérocycliques N-substitués et leurs esters, dans lesquels une chaîne alkyle substituée constitue une partie des N-substituants ou de leurs sels, sur leurs modes de préparation, sur des compositions les contenant, et sur leur emploi pour le traitement clinique d'états douloureux hyperalgésiques et/ou inflammatoires dans lesquels les fibres C jouent un rôle pathophysiologique dans l'apparition de douleurs ou d'inflammations neurogènes.
