The present invention is directed to particle comprising a supramolecular complex comprising a monofunctional and/or a bifunctional subunit comprising a quadruple hydrogen bonding unit, an apolar linker, an urea group, and a polyethyleneglycol linker. The monofunctional subunits comprise a functional group. The particles are very suitable as drug delivery system as they bind and enter the cell and may have slow release properties.
本发明涉及一种颗粒,其包含一个超分子复合物,该复合物包括一个单功能和/或双功能亚基,包括四
重氢键单元、无极性连接剂、
尿素基团和聚
乙二醇连接剂。单功能亚基包括一个功能基团。这些颗粒非常适合作为药物传递系统,因为它们可以结合并进入细胞,并具有缓慢释放的特性。
