A convenient efficient method for synthesis of a flexible cyclic polyamide (cβ, 1) was developed through cyclodimerization. Electrospray ionization mass spectrometry and nuclear magnetic resonance results showed that 1 selectively binds to the c-myb G-quadruplex with high affinity, and there was no binding with the ILPR, bcl-2, and c-kit G-quadruplexes. This is the first time that a flexible cyclic polyamide was found to have high selectivity for the c-myb G-quadruplex.
通过环二聚化，开发了一种方便高效的合成柔性环聚酰胺（cβ，1）的方法。电喷雾电离质谱和核磁共振结果表明，1 选择性地与 c-myb G-四链体高亲和力结合，与 ILPR、bcl-2 和 c-kit G-四链体没有结合。这是首次发现柔性环聚酰胺对 c-myb G-四链体具有高选择性。
