The present invention provides herein the design of monodisperse, amphiphilic anticancer drugs—which are now termed “drug amphiphiles” (DAs)—that can spontaneously associate into discrete, stable supramolecular nanostructures with the potential for self-delivery (no additional carriers are needed). The quantitative drug loading in the resulting nanostructures is ensured by the very nature of the molecular design. The DA is a composition comprising: D-L-PEP; wherein D is 1 to 4 hydrophobic drug molecules which can be the same or different; L is 1 to 4 biodegradable linkers which can be the same or different; and PEP is a peptide that can spontaneously associate into discrete, stable supramolecular nanostructures. In an alternate embodiment, the DA composition also comprises a targeting ligand (T). Methods of making DA molecules, as well as their use in treatment of disease are also provided.
本发明在此提供了单分散、两性抗癌药物的设计,现在被称为“药物两性分子”(DAs),它们可以自发地聚集成离散、稳定的超分子纳米结构,具有自我传递的潜力(无需额外的载体)。由于分子设计的本质,所得纳米结构中的药物负载是定量的。DA是一种包括:D-L-PEP的组合物;其中D是1到4个疏水性药物分子,可以相同也可以不同;L是1到4个可降解的连接剂,可以相同也可以不同;PEP是一种可以自发地聚集成离散、稳定的超分子纳米结构的肽。在另一实施例中,DA组合物还包括一个靶向配体(T)。还提供了制备DA分子的方法,以及它们在治疗疾病中的用途。
