The design and facile synthesis of a novel chiral six-membered PNA analogue (2S,5R )-1-(N-Boc-aminoethyl)-5-(thymin-1-yl)pipecolic acid, aepipPNA, that upon incorporation into PNA sequences effected stabilization of complexes with target complementary DNA. This is the first example where a six membered-PNA is shown to be capable of forming stable complexes with DNA and further expands the repertoire
新型手性六元PNA类似物(2 S,5 R)-1-(N -Boc-氨基乙基)-5-(胸腺嘧啶-1-基)哌酸aepip PNA的设计和合成进入PNA序列可实现与靶互补DNA复合物的稳定化。这是第一个例子,其中六元PNA能够与DNA形成稳定的复合物,并进一步扩展了环状PNA类似物的组成。
