evaluating the efficacy of its analogs in blocking 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone-induced short-term O6-methylguanine and long-term adenoma formation in the lung tissues in A/J mice. Both results revealed cohesive SARs, demonstrating that the methylenedioxy functional group in DHM is essential while the lactone functional group tolerates modifications.
(+)-二氢甲氧苄啶最近被确定为一种有前途的肺癌化学预防剂,而(+)-二氢卡伐他汀则完全无效。探索了体内结构-活性关系的初步试验,评估了其类似物在阻断4-(甲基亚硝胺基)-1-(3-吡啶基)-1-丁酮诱导的短期O 6-甲基鸟嘌呤和长效中的功效。A / J小鼠肺组织中的长期腺瘤形成。两项结果均显示出内聚性SAR,表明DHM中的亚甲二氧基官能团是必不可少的,而内酯官能团则可耐受修饰。
