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.
