The syntheses, structural elucidation based on NMR spectroscopy and X-ray analysis of 8 as well as antitumor activities of novel 2,4-diamino-1,3,5-triazine derivatives 5 and 7-22 are described. Screenings performed at NCI showed that most derivatives possessed a moderate to strong growth inhibition activity on various tumor panel cell lines between 0.148 and 56.2 microM concentrations. 2-Amino-6-bromomethyl-4-(3
描述了合成,基于NMR的结构解析和8的X射线分析以及新型2,4-二氨基-1,3,5-三嗪衍生物5和7-22的抗肿瘤活性。在NCI上进行的筛选显示,大多数衍生物在0.148-56.2 microM浓度的各种肿瘤细胞系上具有中等至强的生长抑制活性。2-Amino-6-bromomethyl-4-(3,5,5-trimethyl-2-pyrazoline)-1,3,5-triazine 11显示出最有效的抗肿瘤活性,其平均中点值为log(10)GI50,所有测试的log(10)TGI50和log(10)LC50分别等于-5.26,-4.81和-4.37,因此,可以将其视为抗癌剂进一步开发的先导结构。
