  Prodrugs based on gemcitabine structure shown in formula (I) as well as their synthetic method and application are disclosed in the present invention, wherein the definitions for the groups of a, b, c, d, E, Z and V are described in the specification. By modifying the N 4 group, the solubility, the bioavailability and the organ specificity of the prodrugs are improved. Therefore, the fast metabolism problem is overcome for the produced prodrugs compounds. Intestinal toxicity induced by gemcitabine is decreased. Thereby, the prodrugs can be delivered by oral administration in clinics and further improve their anti-tumor, anti-cancer, anti-infection and diffusion preventing capability, and can also specifically act on liver or colon. The synthetic method is simple and adapted to industrial production.

  基于吉西他滨结构的前药，如式（I）所示，以及它们的合成方法和应用在本发明中被揭示，其中a、b、c、d、E、Z和V的定义在说明书中描述。通过修改N4基团，改善了前药的溶解性、生物利用度和器官特异性。因此，生产的前药化合物克服了快速代谢问题。吉西他滨引起的肠道毒性减少。因此，前药可以通过口服在临床中投递，并进一步提高其抗肿瘤、抗癌、抗感染和扩散预防能力，还可以特异性地作用于肝脏或结肠。合成方法简单，适用于工业生产。
