摘要
Nucleoside analogues show a variety of biological activities. To prepare new purine nucleoside analogues that could inhibit the proliferation of tumor cells and resist enzyrne hydrolysis, we designed and synthesized 15 different L-5＇noraristeromycin analogues, in which thioether, sulfoxide or sulfone function was introduced to replace the 5＇-hydroxymethyl group. Their anti-tumor activities were assayed in vitro. One compound showed potent anti-tumor activity.
核苷类似物显示了广泛的生物活性。为了寻找具有抗肿瘤活性并同时具有酶稳定性的嘌呤化合物,我们在L-5′-noraristeromycin的5′-位分别引入硫醚、砜、亚砜基团,设计并合成了15个L-5′-noraristeromycin类似物,并测试了这些化合物的体外抗肿瘤活性。一个化合物显示了对肿瘤细胞具有较强抑制活性。
