wherein each of R1, R2, R3, R4, R5, R6, R7, R8, R9 and A has the same meaning as given in the specification.
The present invention relates to a method for exhibiting a virus growth-inhibiting effect and/or a virucidal effect, in which pyrazine nucleotide analog [2] and pyrazine nucleoside analog [3z] are subjected to biotransformation, decomposed and then phosphorylated, so that they become a pyrazine nucleotide analog [1b] exhibiting the aforementioned effect. This method is useful as a method for treating virus infections. Moreover, the pyrazine carboxamide analog or a salt thereof of the present invention is useful as an agent for preventing or treating virus infections.
其中R1、R2、R3、R4、R5、R6、R7、R8、R9和A各自的含义与说明书中给出的含义相同。
本发明涉及一种显示病毒生长抑制作用和/或杀病毒作用的方法,其中吡嗪核苷酸类似物[2]和吡嗪核苷类似物[3z]经过生物转化,分解,然后磷酸化,从而成为显示上述作用的吡嗪核苷酸类似物[1b]。这种方法可用于治疗病毒感染。此外,本发明的吡嗪羧酰胺类似物或其盐可用作预防或治疗病毒感染的药物。
