a very efficient intramolecular acid–base catalysis generating quinone-imine-methide intermediates. Transetherification reactions (i.e., transformation of methyl ethers into isopropyl ethers) are also observed. The reactivity with DNA is studied. Covalent binding to calf-thymus DNA is evidenced by UV–visible analysis of the modified DNA pellets. Ratios of 1 drug bound per 14 base pairs for the 3-methylamino
提出了4-羟甲基-3-(二甲基氨基)-和-3-(甲基氨基)-ac啶的合成以及与亲核试剂的反应。研究了这两种化合物在甲醇和丙-2-醇中的反应性。定量获得相应的4-甲氧基-和4-异丙氧基甲基-3-(烷基氨基)ac啶。动力学数据表明the啶环氮的质子化大大提高了反应速率,其结果有利于产生醌-亚胺-甲基化物中间体的非常有效的分子内酸碱催化。醚醚化反应(即,也观察到了甲基醚向异丙基醚的转化。研究了与DNA的反应性。紫外线-可见的修饰的DNA沉淀分析证明了与小牛胸腺DNA的共价结合。计算3-甲基氨基类似物每14个碱基对结合的1种药物和二甲基类似物每16个碱基对结合的1种药物的比例,对应于与大分子结合的药物的50%。
