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.
本文描述的是嵌段共聚物,以及制造和利用这种共聚物的方法。所述嵌段共聚物可破坏细胞膜,包括细胞外膜、细胞内膜、囊泡、细胞器、内体、脂质体或红细胞。优选地,在某些情况下,嵌段共聚物会破坏膜并进入细胞内环境。在具体例子中,嵌段共聚物具有内溶性,能够将寡核苷酸(如 mRNA)输送到细胞中。此外,还公开了由嵌段共聚物和寡核苷酸(如 mRNA)组成的组合物。
