阳离子聚合物为治疗性核酸的非病毒递送提供了通用平台。为了实现有效的核酸转移,聚合物载体应该包含多个官能团。用于载体内不同递送模块的位点特异性放置的精确化学为揭示进一步优化所需的结构-活性关系提供了基础。在这里,我们提出了42个序列定义的寡(乙氨基)酰胺固相辅助合成产生的库的设计和系统的评价。载体含有用于核酸复合的不同人工寡氨基酸结构域的两臂或四臂拓扑结构,由用于二硫键触发的多聚物稳定的半胱氨酸终止,与用于表面屏蔽的单分散聚乙二醇(PEG)和用于受体特异性细胞摄取的末端叶酸连接。另外的功能元件包括用于内体逃逸的组氨酸和/或用于增强疏水性聚合物稳定性的酪氨酸三聚体。寡聚体文库的体外筛选鉴定了包含组氨酸和酪氨酸三聚体的叶酸-PEG连接的双臂寡阳离子结构作为用于递送pDNA和siRNA的最有效类别的载体。
Cationic polymers present a versatile platform for the nonviral delivery of therapeutic nucleic acids. In order to achieve effective nucleic acid transfer, polymeric carriers ought to comprise multiple functionalities. Precise chemistries for site-specific placements of the different delivery modules within the carriers present the basis for uncovering structure–activity relationships required for further optimization. Here we present the design and systematic evaluation of a library of 42 sequence-defined oligo(ethanamino)amides generated by solid-phase assisted syntheses. The carriers contained two- or four-arm topologies of different artificial oligoamino acid domains for nucleic acid complexation, terminated by cysteines for disulfide-triggered polyplex stabilization, linked with monodisperse polyethylene glycol (PEG) for surface shielding and terminal folic acid for receptor specific cellular uptake. Additional functional elements included histidines for endosomal escape and/or tyrosine trimers for enhanced hydrophobic polyplex stabilization. In vitro screening of the oligomer library identified a folate-PEG-linked two-arm oligocation structure comprising histidines and tyrosine trimers as the most effective class of carriers for the delivery of pDNA and siRNA.
