  Dimeric 1,3-Phenylene-bis(piperazinyl benzimidazole)s: Synthesis and Structure–Activity Investigations on their Binding with Human Telomeric G-Quadruplex DNA and Telomerase Inhibition Properties

  摘要：

  Ligand-induced stabilization of G-quadruplex structures formed by the human telomeric DNA is an active area of research. The compounds which stabilize the G-quadruplexes often lead to telomerase inhibition. Herein we present the results of interaction of new monomeric and dimeric ligands having 1,3-phenylene-bis(piperazinyl benzimidazole) unit with G-quadruplex DNA (G4DNA) formed by human telomeric repeat d[(G(3)T(2)A)(3)G(3)]. These ligands efficiently stabilize the preformed G4DNA in the presence of 100 mM monovalent alkali metal ions. Also, the G4DNA formed in the presence of low concentrations of ligands in 100 mM K+ adopts a highly stable parallel-stranded conformation. The G-quadruplexes formed in the presence of the dimeric compound are more stable than that induced by the corresponding monomeric counterpart. The dimeric ligands having oligo-oxyethylene spacers provide much higher stability to the preformed G4DNA and also exert significantly higher telomerase inhibition activity. Computational aspects have also been discussed.

  bridged cyclophanes (2a and 2b) incorporating bisphenol A units were synthesized and characterized by means of x-ray crystal structure determination. The binding properties of 2a and 2b toward tetramethylammonium, N-methylpyridinium, and acetylcholine cations were evaluated by means of 1H NMR spectroscopy. Consistent with indications provided by the molecular structure, the cavity in the basket-like

  合成了两个新颖的中性聚氧乙烯桥联的双酚A （2a和2b），并通过X射线晶体结构测定对其进行了表征。通过1 H NMR光谱法评价2a和2b对四甲基铵，N-甲基吡啶鎓和乙酰胆碱阳离子的结合特性。与分子结构所提供的指示一致，篮状环烷中的空腔足够大，可以方便地容纳给定的客体阳离子。获得的间接证据表明1,1,2,2-四氯乙烷太大而无法进入较小的环烷2a的腔中，但是可以被包括在较大的Cyclphane 2b的腔中。版权所有©2001 John Wiley＆Sons，Ltd.
