Described herein are block copolymers, and methods of making and utilizing such copolymers. The described block copolymers are disruptive of a cellular membrane, including an extracellular membrane, an intracellular membrane, a vesicle, an organelle, an endosome, a liposome, or a red blood cell. Preferably, in certain instances, the block copolymer disrupts the membrane and enters the intracellular environment. In specific examples, the block copolymer is endosomolytic and capable of delivering an oligonucleotide (e.g., an mRNA) to a cell. Compositions comprising a block copolymer and an oligonucleotide (e.g., an mRNA) are also disclosed.
本文描述了嵌段共聚物以及制备和利用这种共聚物的方法。所述的嵌段共聚物破坏细胞膜,包括细胞外膜、细胞内膜、囊泡、细胞器、内体、脂质体或红细胞。在某些情况下,该嵌段共聚物会破坏膜并进入细胞内环境。在具体示例中,该嵌段共聚物具有内体溶解作用,并能够将寡核苷酸(例如mRNA)传递到细胞中。还公开了包含嵌段共聚物和寡核苷酸(例如mRNA)的组合物。
