A cyclic molecule including a hexameric PNA sequence has been designed and synthesized in order to target the TAR RNA loop of HIV-1 through the formation of a "kissing complex". For comparison, its linear analogue has also been investigated. The synthesis of the cyclic and linear PNA has been accomplished following a liquid-phase strategy using mixed PNA and fully N-protected (aminoethylglycinamide)
设计并合成了包含六聚体PNA序列的环状分子,以通过形成“类似复合物”靶向HIV-1的TAR RNA环。为了比较,还研究了其线性类似物。环状和线性PNA的合成已按照液相策略,使用混合的PNA和完全N保护的(氨基乙基甘氨酰胺)片段完成。已经研究了该环状PNA及其线性类似物与TAR RNA的相互作用,结果清楚地表明,环状反义PNA与TAR RNA之间未发生相互作用,而其线性PNA类似物检测到微弱的相互作用。
