A series of new 2-aminonaphthoquinones and related compounds were synthesized and evaluated in vitro as trypanocidal and cytotoxic agents. Some tested compounds inhibited epimastigote growth and trypomastigote viability. Several compounds showed similar or higher activity and selectivity as compared with current trypanocidal drug, nifurtimox. Compound 4l exhibit higher selectivity than nifurtimox against
合成了一系列新的2-氨基萘醌和相关化合物,并在体外评估了其为锥虫和细胞毒剂。一些经过测试的化合物抑制了前鞭毛体的生长和锥鞭毛体的生存能力。与目前的锥虫杀灭药硝呋替莫相比,几种化合物显示出相似或更高的活性和选择性。与Vero细胞相比,化合物4l对尼古丁对克鲁斯锥虫的选择性更高。测试了一些合成的醌类对癌细胞和正常成纤维细胞的影响,表明萘醌部分的某些化学修饰可诱导并显着提高细胞毒性的选择性指数(4g和10)。此处给出的结果表明,2-氨基萘醌衍生物的抗T. cruzi活性可以通过用吡啶部分取代苯环来提高。有趣的是,C-3上存在氯原子和高度亲脂性烷基或芳环是新近观察到的元素,应导致发现更具选择性的细胞毒性和锥虫性化合物。
