The synthesis and interaction of N,N',N'',N'''-tetramethyl-2,6,9,13-tetraaza[14]paracyclophanes (B323Me(4)) with nucleotides and inorganic phosphates is described. An easy methodology is used to define thermodynamic selectivity. The interaction of B323Me4 and ATP has been monitored by (1)H, (31)P NMR and by molecular mechanics, ruling out the possibility of the participation of pi-stacking interactions
描述了N,N',N'',N'''-四甲基-2,6,9,13-四氮杂[14]对环环烷(B323Me(4))与核苷酸和无机磷酸盐的合成和相互作用。一种简单的方法用于定义热力学选择性。B323Me4与ATP的相互作用已通过(1)H,(31)P NMR和分子力学进行了监测,排除了pi堆积相互作用参与的可能性。结果表明,N-甲基化伴随着所产生的大环与ATP相互作用的强烈增加。
