This invention discloses compositions and methods for preparing chloroquine-coupled nucleic acid compositions. The prior art has shown that chloroquines given as free drug in high enough concentration, enhances the release of various agents from cellular endosomes into the cytoplasm. The purpose of these compositions is to provide a controlled amount of chloroquine at the same site where the nucleic acid needs to be released, thereby reducing the overall dosage needed. The compositions comprise a chloroquine substance coupled to a nucleic acid directly or through a variety of pharmaceutical carrier substances. The carrier substances include polysaccharides, synthetic polymers, proteins, micelles and other substances for carrying and releasing the chloroquine compositions in the body for therapeutic effect. The compositions can also include a biocleavable linkage for carrying and releasing nucleic acids for therapeutic or other medical uses. The invention also discloses nucleic acid carrier compositions that are coupled to targeting molecules for targeting the delivery of nucleic acids to their site of action.
本发明披露了制备
氯喹偶联核酸组合物的组成和方法。先前的研究表明,以足够高的浓度给予
氯喹作为自由药物,可以增强细胞内体内各种物质从内体泡中释放到细胞质中。这些组合物的目的是在核酸需要释放的同一位置提供受控量的
氯喹,从而降低所需的总剂量。该组合物包括直接或通过各种药物载体物质偶联的
氯喹物质和核酸。载体物质包括
多糖、合成聚合物、蛋白质、胶束和其他用于在体内携带和释放
氯喹组合物以达到治疗效果的物质。该组合物还可以包括
生物可降解连接来携带和释放用于治疗或其他医疗用途的核酸。本发明还披露了偶联到靶向分子的核酸载体组合物,用于将核酸传递到其作用位置。
