Inventor: WAGNER FRED W
IPC: C12R1/19
Filed: 1994-07-19
Abstract: Procédé de formation d'un polypeptide recombiné dont l'extrémité C-terminale est modifiée par un processus de transpeptidation. Le procédé convient à la modification de polypeptides recombinés de quelque source que ce soit, et notamment de ceux que l'on est susceptible de trouver dans le commerce, de ceux dérivés de structures polypeptidiques recombinées à copie unique ou à copies multiples, ou de ceux dérivés de structures protéiques hybrides recombinées à copie unique ou à copies multiples. La réaction de transpeptidation comporte la mise en contact d'une endopeptidase et d'un polypeptide recombiné afin de remplacer un motif labile lié à un polypeptide de noyau par l'intermédiaire d'un site de clivage reconnu par l'endopeptidase, par un motif d'addition d'un ou plusieurs acides aminés. Les polypeptides recombinés dérivés de structures polypeptidiques à copies multiples peuvent être séparés par clivage du polypeptide à copies multiples au nivau des extrémités N-terminale et C-terminale, et subissent simultanément le remplacement du motif labile par le motif d'addition voulu. Le procédé met en oeuvre des sites de reconnaissance de clivage connus et découverts récemment afin d'obtenir les produits de modification voulus.

IPC: A61P25/02
Filed: 1995-02-15
Abstract: L'invention concerne une série de nouveaux peptides opioïdes destinés au traitement de la douleur, ainsi que des compositions pharmaceutiquement acceptables contenant lesdits peptides. L'invention concerne également des procédés de lutte contre la douleur chez des patients utilisant des compositions de l'invention. Les peptides de cette invention présentent un degré élevé de sélectivité vis-à-vis du récepteur de µ-opioïdes. Ces peptides sont hautement lipophiles. Malgré leur caratère lipophile, ils ne traversent pas facilement la barrière hémato-encéphalique. Les peptides de l'invention sont particulièrement bien adaptés en tant qu'agents analgésiques agissant sensiblement sur les récepteurs µ d'opioïdes périphériques. Etant donné que ces peptides agissent de manière périphérique, ils sont sensiblement exempts d'effets secondaires normalement associés à une action analgésique centrale.
