5-Fluorouracil derivatives of this invention are represented by a general formula:
wherein R indicates a non-substituted or substituted alkylene group having 0-10 carbon atoms, A indicates an atomic group of -NH- and -CO-, n is 0 or 1, and Y indicates a non-substituted or substituted alkyl group having 1-10 carbon atoms, a non-substituted or substituted aryl group, a non-substituted or substituted heteroaryl group, a pyridinium ion having a halogen as a pair ion or an isocyanate group.
These derivatives are useful as anticancer medicines and intermediates thereof and have lower toxicity than usual compounds.
These derivatives are produced by specified six methods of this invention. Representative method is a process which comprises reacting 5-fluorouracil and an isocyanate represented by a general formula:
Y - (A) n - R - NCO (VII)
wherein R, A, n and Y are the same as those indicated in the formula (I).
本发明的5-氟尿嘧啶衍生物由通式表示:
其中 R 表示具有 0-10 个碳原子的非取代或取代的亚烷基,A 表示 -NH- 和 -CO- 的原子团,n 为 0 或 1,Y 表示具有 1-10 个碳原子的非取代或取代的烷基、非取代或取代的芳基、非取代或取代的杂芳基、具有卤素作为配对离子的吡啶鎓离子或异氰酸酯基团。
这些衍生物可用作抗癌药物及其中间体,其毒性低于普通化合物。
这些衍生物是通过本发明指定的六种方法生产出来的。具有代表性的方法是将 5-氟尿嘧啶和由通式表示的异氰酸酯进行反应:
Y - (A) n - R - NCO (VII)
其中 R、A、n 和 Y 与式(I)中所表示的相同。
