    基于吉西他滨结构的口服前药的合成及生物学评价
    摘要:
    通过在胞苷环的N4位引入一个酰胺基,合成了一系列基于吉西他滨(2',2'-二氟脱氧胞苷)结构的口服前药。总共获得了16种化合物,并对其化学和生物学特性进行了评估。这些化合物大多数的半数最大抑制浓度(IC 50 s)在体外高于吉西他滨。根据化合物5d和5m的生理稳定性和药代动力学对其进行了检查。复合5d在PBS和模拟肠液中显示出良好的稳定性,对小鼠的药代动力学分析表明,吉西他滨引入酰胺基可以大大提高其生物利用度。在体内对化合物5d的进一步评估表明,该化合物对HepG2人肝癌细胞和HCT-116结肠腺癌细胞的生长具有比吉西他滨更高的活性,并且对动物的毒性较小。这些结果表明,化合物5d可以进一步开发为潜在的口服抗癌剂,用于目前正在使用吉西他滨的临床应用中。

    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。
