Preparation of the nucleoside analogues 1 and incorporation of 1, B = T, in deoxyribooligonucleotides by the phosphoramidite method is described. A two-step deprotection procedure was developed to reduce cleavage of the modified allylic unit. The binding properties of the modified oligonucleotides towards complementary DNA and RNA has been evaluated by Tm measurements showing a deltaTm of -2 to -6
描述了通过亚磷酰胺方法在脱氧核糖寡核苷酸中制备核苷类似物1和掺入1,B = T。开发了两步脱保护程序以减少修饰的烯丙基单元的裂解。已通过Tm测量评估了修饰的寡核苷酸对互补DNA和RNA的结合特性,显示出每次修饰的ΔTm为-2至-6.5℃。在3'-末端具有两个修饰的寡核苷酸显示出对3'-核酸外切酶切割的抗性。对于1,B = G或T或任何三羟基衍生物5,未发现针对HIV-1或HSV-1的抗病毒活性。
