Aminoalcohol lipidoids are prepared by reacting an amine with an epoxide-terminated compound are described. Methods of preparing aminoalcohol lipidoids from commercially available starting materials are also provided. Aminoalcohol lipidoids may be prepared from racemic or stereochemically pure epoxides. Aminoalcohol lipidoids or salts forms thereof are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the amino moiety of these aminoalcohol lipidoid compounds, they are particularly suited for the delivery of polynucleotides. Complexes, micelles, liposomes or particles containing the inventive lipidoids and polynucleotide have been prepared. The inventive lipidoids may also be used in preparing microparticles for drug delivery. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings.
本文描述了通过将胺与环氧末端化合物反应制备氨基醇脂质体的方法。还提供了从商业起始材料制备氨基醇脂质体的方法。氨基醇脂质体可以从外消旋或立体化学纯的环氧化合物制备。氨基醇脂质体或其盐形式最好是可生物降解和生物相容的,并可用于各种药物输送系统。鉴于这些氨基醇脂质体化合物的氨基基团,它们特别适用于多核苷酸的输送。已经制备了包含创新脂质体和多核苷酸的复合物、胶束、脂质体或粒子。创新脂质体也可以用于制备药物输送的微粒。鉴于它们能够缓冲其周围环境的pH值,它们在输送不稳定剂方面特别有用。
