中文摘要：

嘧啶类化合物因其广泛的生物活性在医药、农药等领域备受关注,特别是近年来大量具有抗肿瘤活性的嘧啶类化合物被报道,其中一些化合物已进入临床试验阶段。虽然这些化合物都含有嘧啶结构,但它们的作用机制却表现出多样性。如抑制细胞周期蛋白依赖性激酶、酪氨酸蛋白激酶、碳酸酐酶、二氢叶酸还原酶和干扰微管蛋白聚合等。本文将根据嘧啶类化合物的作用靶点,介绍其在抗肿瘤药物研究中的最新进展。

英文摘要：

Pyrimidine derivatives have been the subject of much attention in pesticide and medicine fields owing to their unique biological properties.Particularly,a large number of these compounds have recently been reported to show substantial antitumor activities,and some of them have been investigated in clinical trials.Although these structurally novel compounds have a common chemical moiety of a pyrimidine ring,there are a variety of mechanisms of their antitumor action,such as,inhibition of cyclin-dependent-kinases,inhibition of protein tyrosine kinase,inhibition of carbonic anhydrases,inhibition of dihydrofolate reductase and disruption of microtubule assembly.In this paper,we described the latest advances in the research of such pyrimidine derivatives as antitumor drug according to their action on targets.
