Cyclopropane derivatives of the following general formula (I) or their pharmaceutically acceptable salts, are provided, as well as anti-viral agents containing the same as the active ingredient:
wherein R¹ and R², which may be the same or different, each represents a hydrogen atom or an acyl group; R³ represents a halogen atom, a 2-haloalkyl group, a 2-halo-1-alkenyl group, or a 1-alkynyl group. The derivatives and their salts have anti-viral activity, for example against varicella zoster and herpes simplex, and may be used as alternatives to acyclovir. And intermediates of formulae (3) and (9)
wherein R₄ is a protective group for a hydroxyl group and R₃ is defined as above.
提供了以下通式(I)的环丙烷衍生物或其药学上可接受的盐类,以及含有相同活性成分的抗病毒制剂:
其中R¹和R²可以相同或不同,各自代表氢原子或酰基;R³代表卤素原子、2-卤代烷基、2-卤代-1-烯基或1-炔基。这些衍生物及其盐类具有抗病毒活性,例如抗水痘带状疱疹和单纯疱疹,可用作阿昔洛韦的替代品。以及式 (3) 和 (9) 的中间体
其中 R₄ 是羟基的保护基团,R₃ 的定义同上。
