A seriesof twenty four acyclic unsaturated 2,6-substututed purines 5a-20b were synthesized. These compounds were evaluated for cytotoxic activity against NCI-60 DTP human tumor cell line screen at 10µMconcentration. N9-[(Z)-4'-chloro-2'-butenyl-1'-yl]-2,6-dichloropurine(5a), N9-[4'-chloro-2'-butynyl-1'-yl]-2,6-dichloropurine(10a), N9-[(E)-2',3'-dibromo-4'-chloro-2'-butenyl-1'-yl]-6-methoxypurine(14)and N9-[4'-chloro-2'-butynyl-1'-yl]-6-(4-methoxyphenyl)-purine(19)exhibited highly potent cytotoxic activity with GI50 values in the 1–5 µM range for most human tumor cell lines. Other compounds exhibited moderate activity.
共合成了24种非环状不饱和2,6-取代嘌呤衍生物5a-20b。这些化合物在10微摩尔浓度下,针对NCI-60 DTP人肿瘤细胞系进行了细胞毒活性评估。其中,N9-[(Z)-4'-氯-2'-丁烯-1'-基]-2,6-二氯嘌呤(5a)、N9-[4'-氯-2'-丁炔-1'-基]-2,6-二氯嘌呤(10a)、N9-[(E)-2',3'-二溴-4'-氯-2'-丁烯-1'-基]-6-甲氧基嘌呤(14)以及N9-[4'-氯-2'-丁炔-1'-基]-6-(4-甲氧苯基)嘌呤(19)显示出极强的细胞毒活性,对大多数人肿瘤细胞系的GI50值在1至5微摩尔范围内。其他化合物表现出中等活性。
