Supramolecular Self-Assembling Cyanine as an Alternative to Ethidium Bromide Displacement in DNA–Drug Model Interactions during High Throughput Screening
Supramolecular Self-Assembling Cyanine Ethidium Bromide Displacement DNA–Drug Model
2010/9/17
Supramolecular self-assembling cyanine and spermine binding to genomic DNA was a model for DNA–drug interactions during high throughput screening. Spermine competitively inhibited the self-assembly of...
用电化学方法研究了丁二酮肟双核铜配合物[Cu2(Hdmg)4]与DNA的相互作用. 考察了pH、温度、离子强度和配合物浓度等因素对配合物与DNA相互作用的影响, 初步探讨了配合物与DNA相互作用的机理. 实验结果表明, 配合物与DNA的碱基结合形成非电活性物质, 使溶液中游离配合物的浓度降低, 配合物的峰电流减小. 单链DNA(ssDNA)充分暴露的碱基使其与配合物的结合能力大于双链DNA(dsD...
研究了鸟嘌呤(G)、腺嘌呤(A)、鸟嘌呤核苷、腺嘌呤核苷和变性DNA在电化学预处理玻碳电极上的恒电流微分计时电位溶出行为. 实验结果表明, 用电化学方法预处理玻碳电极操作简单, 效果明显, 预处理玻碳电极对嘌呤及其核苷和DNA的吸附能力大大增强, 用微分计时电位溶出法可以得到灵敏的溶出峰, 溶出峰高(dt/dE)与其浓度在一定范围内呈良好的线性关系, 可用于嘌呤碱基及其核苷的定量检测和DNA浓度的...
