A series of aryl and acyclic unsaturated chloromethyl derivatives of thioguanine and 6-mercaptopurine 1-20 were synthesized. These compounds were evaluated for cytotoxic activity against NCI-60 DTP human tumor cell line screen at 10µ Molar concentration. Compound 1 exhibited potent cytotoxic activity with GI50 values 1 - 7 µ Molar range for most human tumor cell lines. Further, compounds 6, 9, 16 exhibited highly significant GI50 values 1 - 3 µ Molar range throghout the entire spectrum of the 60 cell line screen including the colon cancer and CNS cancer. Other compounds exhibited moderate activity.
一系列苯基和无环不饱和氯甲基嘌呤类似物(包括硫鸟嘌呤和6-巯基嘌呤的衍生物1-20)已被合成。这些化合物在10微摩尔浓度下,针对NCI-60 DTP人类肿瘤细胞系筛选进行了细胞毒性活性评估。化合物1显示出强烈的细胞毒性活性,对于多数人类肿瘤细胞系的GI50值在1至7微摩尔范围内。进一步地,化合物6、9、16在整个包含结肠癌和中枢神经系统癌症的60个细胞系筛选中,表现出非常显著的GI50值,范围在1至3微摩尔内。其他化合物则表现出中等的活性。
