2′‐Deoxyadenosine triphosphate (dATP) derivatives bearing diverse substituents (Cl, NH2, CH3, vinyl, ethynyl, and phenyl) at position 2 were prepared and tested as substrates for DNA polymerases. The 2‐phenyl‐dATP was not a substrate for DNA polymerases, but the dATPs bearing smaller substituents were good substrates in primer‐extension experiments, producing DNA substituted in the minor groove. The
制备了2位带有2个不同取代基(Cl,NH 2,CH 3,乙烯基,乙炔基和苯基)的2'-脱氧腺苷三磷酸(dATP)衍生物,并作为DNA聚合酶的底物进行了测试。2-苯基-dATP不是DNA聚合酶的底物,但是带有较小取代基的dATP在引物延伸实验中是良好的底物,在小沟中产生了被取代的DNA。乙烯基修饰的DNA用于硫醇-烯加成,乙炔基修饰的DNA用于CuAAC点击反应,以在小沟中形成标记有荧光染料的DNA
