Abstract[English]
The present disclosure relates to processes for preparation of a peptide powder, and the preparation of peptide particles, for example a GLP-1 peptide such as Liraglutide, Dulaglutide, Exanetide, Lixisenatide and/or Semaglutide, and/or a salt thereof; particularly Liraglutide and Semaglutide and salts thereof; preferably Semaglutide and salts thereof, and more preferably Semaglutide. More specifically, the disclosure relates to a process comprising lyophilizing a solution comprising the peptide; and particle size reduction of the obtained lyophilizate. The disclosure further relates to GLP-1 peptides, particularly wherein the GLP-1 peptide is selected from Liraglutide, Dulaglutide, Exanetide, Lixisenatide and/or Semaglutide, and/or a salt thereof; preferably selected from Liraglutide and Semaglutide, and a salt thereof; and more preferably Semaglutide and a salt thereof, and most preferably Semaglutide, obtainable by said process and its use in medicine and cosmetic treatment.[French]
La présente divulgation concerne des processus de préparation d'une poudre peptidique, et la préparation de particules peptidiques, par exemple un peptide GLP-1 tel que le Liraglutide, le Dulaglutide, l'Exanetide, le Lixisenatide et/ou le Sémaglutide, et/ou leurs sels ; en particulier le Liraglutide et le Sémaglutide et leurs sels ; de préférence le Sémaglutide et ses sels, et de manière davantage préférée le Sémaglutide. Plus spécifiquement, la divulgation concerne un processus comprenant la lyophilisation d'une solution comprenant le peptide ; et la réduction de la taille des particules du lyophilisat obtenu. La divulgation concerne en outre des peptides GLP-1, le peptide GLP-1 étant en particulier choisi parmi le Liraglutide, le Dulaglutide, l'Exanetide, le Lixisenatide et/ou le Sémaglutide, et/ou leurs sels ; de préférence choisi parmi le Liraglutide et le Sémaglutide, et leurs sels ; et de manière davantage préférée le Sémaglutide et un sel de celui-ci, et de manière préférée entre toutes le Sémaglutide, pouvant être obtenu par ledit processus et son utilisation en médecine et dans un traitement cosmétique.
