The present invention relates to novel types of peptide nucleic acids (PNAS) with improved properties. In particular, it relates to positively charged PNA units having an ethylene linker between the backbone and the nucleobase, to oligonucleotide analogs comprising these units, to oligomers comprising these units, and to the use of positively charged PNAs as novel delivery agents with therapeutic and diagnostic applications including for antisense therapy.
本发明涉及具有改进性能的新型肽核酸(PNA)类型。具体而言,涉及具有乙烯连接剂的带正电荷的PNA单元,该连接剂位于骨架和核碱基之间,以及包含这些单元的寡核苷酸类似物、包含这些单元的寡聚体,以及将带正电荷的PNA用作新型传递剂的用途,包括用于反义疗法的治疗和诊断应用。
