antigene DNA recognition strategies, a uriedo-isoindolin-1-one homo-N-nucleoside base was designed to bind the cytosine-guanine (CG) base pair. An organic soluble analogue of this base was shown to effectively complex CG (K(assoc)=740M(-1)) in chloroform through formation of three hydrogen bonds (Mertz, E.; Mattei, S.; Zimmerman, S. C. Org. Lett. 2000, 2, 2931-2934). The novel nucleoside base was synthesized
为了构建用于基于三链体的抗原DNA识别策略的非天然碱基,设计了一个uriedo-isoindolin-1-one同源N-核苷碱基来结合胞嘧啶-鸟嘌呤(CG)碱基对。通过形成三个氢键(Mertz,E .; Mattei,S .; Zimmerman,SC Org。Lett),显示该碱的有机可溶性类似物可有效地使其在氯仿中络合CG(K(assoc)= 740M(-1))。 (2000,2,2931-2934)。合成了新的核苷碱基并将其成功掺入用于三重螺旋熔化温度研究的寡核苷酸中。当异吲哚啉-1-酮碱基与CG以及GC,TA和AT配对时观察到较低的熔融温度,因此表明尽管在模型研究中得到了认可,
