通过控制反应条件, 制备得到1-对甲苯磺酰基-3-羟基-1,5,8-三氮杂环癸烷(2). 根据谱学数据确定目标化合物2的结构, 应用DNA熔点温度测量和计算机模拟研究测定化合物2～4与DNA的结合能力. 结果显示羟基和对甲苯磺酰基的引入有利于化合物2与DNA的结合. 在37 ℃生理条件作用下, 不需要金属离子辅助, 大环配体2可使超螺旋型pBR322 DNA断裂, 同时得到切口开环型和线形DNA. 并且, 化合物2对肺癌细胞有选择性抑制作用. 因此, 这种先导化合物可以用于人工核酸酶及抗肿瘤药物设计.

In this paper, 1-tosyl-3-hydroxyl-1,5,8-triazacyclodecane (2) was prepared in optimized conditions. The structure of title compound 2 was established on the basis of spectroscopic data. The binding of compounds 2, 3, 4 to DNA was investigated with melting temperature measurements and molecular-modeling calculations. The results showed that the introduction of hydroxyl and tosyl groups into triazacyclicamines may enhance the interaction between the compound 2 and DNA. The free macrocyclic ligand 2 could catalyze cleavage supercoiled pBR322 DNA to the nicked and the linear form at the same time at near neutral conditions and 37 ℃ without any metal ions aid. In addition, compound 2 showed selectively inhibition to lung cancer cells. Thus, this leading compound might be useful as artificial restriction enzymes and may be usefully applied in the development of anti-tumor drug.

Key words: macrocyclic polyamines, DNA cleavage, interaction, antitumor activity
