Abstract[English]
The present disclosure includes cationic carrier units comprising (i) a water-soluble polymer, (ii) a positively charged carrier, and (iii) a hydrophobic moiety, wherein the cationic carrier unit does not comprise a crosslinking moiety and wherein when the cationic carrier unit is mixed with an anionic payload (e.g., an antisense oligonucleotide) that electrostatically interacts with the cationic carrier unit, the resulting composition self-organizes into a micelle encapsulating the anionic payload in its core.[French]
La présente divulgation comprend des unités de vecteurs cationiques comprenant (i) un polymère hydrosoluble, (ii) un vecteur chargé positivement et (iii) un fragment hydrophobe. L'unité de vecteur cationique ne comprend pas de fragment de réticulation et, lorsque l'unité de vecteur cationique est mélangée avec un charge utile anionique (par exemple, un oligonucléotide antisens) qui interagit par effet électrostatique avec l'unité de vecteur cationique, la composition résultante s'auto-organise en une micelle encapsulant la charge utile anionique dans son noyau.
