The invention provides polymers comprising Formula I:
wherein monomer is a repeating unit comprising 2, 3, 4, 5, 6 or 7 carbon atoms and the monomers are linked together through amide or ester bonds; n is about 6 to about 1000; and Linker is an optionally substituted carbon chain that is optionally interrupted by moieties such as oxygen, nitrogen, sulfur, phosphorus, or silicon. Charge is a moiety having a positive or negative charge on a heteroatom, such as nitrogen, oxygen, phosphorus, or sulfur; where the Linker separates the monomer and the Charge by at least six linear atoms. The invention also provides methods of preparing the polymers and the copolymers and methods of using the polymers and copolymers, for example, as drug delivery systems, as membrane penetrating peptides, and as therapeutic agents.
本发明提供了包含式 I 的聚合物:
其中,单体是由 2、3、4、5、6 或 7 个碳原子组成的重复单元,单体通过酰胺键或酯键连接在一起;n 约为 6 至约 1000;连接体是任选取代的碳链,可任选被氧、氮、
硫、
磷或
硅等分子打断。电荷是杂原子(如氮、氧、
磷或
硫)上带有正电荷或负电荷的分子;其中连接体将单体和电荷隔开至少六个线性原子。本发明还提供了制备聚合物和共聚物的方法,以及使用聚合物和共聚物的方法,例如用作药物输送系统、膜穿透肽和治疗剂。
