This invention pertains to certain hypercoiling polymers, and their use for the delivery of a payload into a living cell, e.g., into the nucleus of a living cell, which polymer incorporates, or is otherwise associated with, said payload. The payload may be, for example, a therapeutic payload, such as a drug, etc.; a diagnostic payload, such as a detectable label, such as a fluorophore, etc. In preferred embodiments, the hypercoiling polymers are biocompatible; biodegradable; comprise amide linkages; and/or are pseudo-proteins. The present invention also pertains to certain hypercoiling polymers; certain hypercoiling carrier polymers, which incorporate a payload; and certain hypercoiling carrier polymers, otherwise associated with a payload; which are suitable for use in such methods; and methods of diagnosis, treatment, imaging, etc., using such polymers.
本发明涉及某些超螺旋聚合物及其用于将有效载荷递送到活细胞中,例如递送到活细胞的细胞核中,该聚合物包含或与所述有效载荷相关联。有效载荷可以是治疗有效载荷,例如药物等;诊断有效载荷,例如可检测的标记,如荧光染料等。在优选实施例中,超螺旋聚合物具有生物相容性;可生物降解;包含酰胺键;和/或是伪蛋白质。本发明还涉及某些超螺旋聚合物;某些携带有效载荷的超螺旋载体聚合物;以及某些与有效载荷相关联的超螺旋载体聚合物;它们适用于这种方法的使用;以及使用这样的聚合物进行诊断、治疗、成像等的方法。
