Abstract We have developed an improved scheme for the synthesis of a mono-fluorinated phosphoramidite for the 5’-modification of nucleic acids using standard phosphoramidite chemistry. We describe the first report of a phosphofluoridate modified siRNA strand and have evaluated C18 HPLC for purification of modified strands from unreacted siRNA strands. Lastly, the biological activity of the high purity
摘要 我们开发了一种改进方案,用于使用标准亚磷酰胺化学合成单氟化亚磷酰胺,用于核酸 5'-修饰。我们描述了磷酸氟化物修饰的 siRNA 链的第一份报告,并评估了 C18 HPLC 从未反应的 siRNA 链中纯化修饰链。最后,评估高纯度 siRNA 链在有义和/或反义链上的生物活性,以评估 5' 磷酸氟化物修饰对 siRNA 活性的影响。
