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.
该发明提供了包含以下结构的聚合物:
其中单体是包含2、3、4、5、6或7个碳原子的重复单元,而单体通过酰胺或酯键连接在一起;n约为6至1000;连接物是一种可选择地被氧、氮、硫、磷或硅等基团中断的可选择替代的碳链。电荷是在杂原子(如氮、氧、磷或硫)上具有正电荷或负电荷的基团;其中连接物至少由六个线性原子将单体和电荷分开。该发明还提供了制备这些聚合物和共聚物的方法,以及使用这些聚合物和共聚物的方法,例如作为药物传递系统、膜穿透肽和治疗剂。
