Patent

CA 2478066

An amphiphilic compound is provided capable of forming vesicles or liposomes, said amphiphilic compound having at least one headgroup containing a selectively cleavable group or moiety such as a residue of a choline or phenylalanine derivative, and at least one hydrogen-bonding group located either within said headgroup and/or in close proximity thereto. The cleavable group or moiety is cleaved under selective conditions including change of chemical, physical or biological environment and is preferably cleaved enzymatically in a biological environment such as the brain or the blood. Vesicles or liposomes made from said amphiphilic compounds are suitable for delivery of a therapeutic substance or a diagnostic agent specifically to a target organ or tissue, or for delivery of a nucleic acid for gene therapy.

L'invention concerne un composé amphiphilique capable de fabriquer des vésicules ou des liposomes, ce composé présentant au moins un groupe de tête contenant un groupe ou une fraction pouvant être clivés de manière sélective tels qu'un résidu de choline ou un dérivé de phénylalanine, et au moins un groupe à liaison hydrogène situé dans ledit groupe de tête et/ou à proximité de ce dernier. Le groupe ou la fraction pouvant être clivés sont clivés dans des conditions sélectives consistant à changer l'environnement chimique, physique ou biologique et subissent, de préférence, un clivage enzymatique dans un environnement biologique tel que le cerveau ou le sang. Les vésicules ou les liposomes fabriqués à partir de ces composés amphiphiliques conviennent à l'administration spécifique d'une substance thérapeutique ou d'un agent diagnostique sur un organe ou un tissu cibles, ou à l'administration d'un acide nucléique pour la thérapie génique.
