工作介绍
核酸化学合成:亚磷酰胺法
从1950年代开始,化学家们就开始了核酸的化学合成研究,但直到1980年,广泛使用的仍是收率低,中间体稳定性差的磷酸二酯法,磷酸三酯法和亚磷酸三酯法。在核酸合成中,由于分子间的偶联反应重复使用,因此产率需要尽可能接近100%。从1980年代开始,化学家们开始尝试核酸自动合成,可用于核酸合成的高产率条件温和的偶联反应开发迫在眉睫。
Caruthers教授开发了使用亚磷酰胺中间体化学合成核酸的方法,其中亚磷酰胺(图1)的膦分别与核苷或脱氧核苷,氰基乙氧基和二烷基氨基结合。亚磷酰胺中间体在酸性条件下与固定性负载的核苷反应,构建核酸中核苷与磷酸纸间的O-P键,然后通过碘等氧化剂氧化即可得到目标的亚磷酸三酯结构。由于亚磷酰胺相对稳定可长期保存,且反应收率高,因此该反应作为核酸合成中的一种普适方法而被广泛使用。
