Title (EN) COMPOSITION AND METHOD FOR A PREBIOTIC DELIVERY SYSTEM TARGETED TO PROBIOTIC BACTERIA
(FR) COMPOSITION ET PROCÉDÉ POUR UN SYSTÈME D'ADMINISTRATION DE PRÉBIOTIQUES CIBLANT DES BACTÉRIES PROBIOTIQUES
Abstract:
(EN) Provided herein is a particle made of a protein covalently bound to a prebiotic carbohydrate, thereby forming a conjugate, wherein at least two said conjugates are covalently crosslinked via their carbohydrate units (e.g. by a phospho-di-ester bond). The said particle may be used for selectively promoting probiotic bacteria growth in the colon and may be used to deliver additional probiotic growth factors, or other bioactives and drugs to the colon. Furthermore, provided herein are methods for preparing the particle, and for delivering a substance bound to, or entrapped within the particle, into the gastrointestinal tract of a subject in need thereof.
(FR) La présente invention concerne une particule constituée d'une protéine liée de manière covalente à un glucide prébiotique, formant ainsi un conjugué, au moins deux dits conjugués étant réticulés de manière covalente par l'intermédiaire de leurs unités glucidiques (par exemple par une liaison phosphodiester). Ladite particule peut être utilisée pour favoriser sélectivement la croissance de bactéries probiotiques dans le côlon et peut être utilisée pour administrer des facteurs de croissance probiotiques supplémentaires, ou d'autres produits bioactifs et d'autres médicaments au côlon. En outre, l'invention concerne des procédés de préparation de la particule, et d'administration d'une substance liée à la particule ou piégée à l'intérieur de celle-ci, dans le tractus gastro-intestinal d'un sujet en ayant besoin.
