Oligonucleotides containing enantiomeric carbocyclic oxetanocins possessing adenine, thymine, guanine and cytosine were synthesized from an optically active cyclobutane derivative. Their hybridization properties with the complementary oligonucleotides were studied using melting point method, CD spectroscopy, and mixing curve method (Job plots). The artificial nucleotides possessing adenine, guanine
从具有光学活性的环丁烷衍生物合成含有对映体碳环氧etanocins的寡核苷酸,该对映体具有腺嘌呤,胸腺嘧啶,鸟嘌呤和胞嘧啶。使用熔点法,CD光谱法和混合曲线法(乔布图)研究了它们与互补寡核苷酸的杂交特性。具有腺嘌呤,鸟嘌呤和胞嘧啶碱基的人工核苷酸显示出比脱氧核糖核苷酸更容易与核糖核苷酸形成复合物的趋势。这些复合物是由嘌呤和嘧啶以1:2的比例组成的三链体。在高(1 M NaCl)和低盐(0.1 M NaCl)条件下都观察到了这种三链体的形成。
