Transport reagents and conjugates of therapeutic agents linked to transport reagents are described. In particular, the transport reagents have a plurality of guanidinium moieties that are either contiguous or spaced along a backbone, but are sufficiently removed from the backbone via tethers, to allow their interaction with a cell or tissue surface, leading to uptake of the therapeutic agent.

胍基官能团,这些官能团可以连续或分散地沿着骨架分布,但由于骨架上的鞭毛足够远离,从而允许它们与细胞或组织表面相互作用,导致治疗剂的摄取。
