The present invention relates to the discovery that certain P-L-dioxolane nucleoside analogs which contain a uracil base, and preferably, a 5-halosubstituted uracil base, exhibit unexpectedly high activity against Epstein-Barr virus (EBV), Varciella-Zoster virus (VZV) and Herpes Virus 8 (HV-8). In particular, the compounds according to the present invention show potent inhibition of the replication of the virus (viral growth) in combination with very low toxicity to the host cells (i.e., animal or human tissue). Compounds are useful for treating EBV, VZV and HV-8 infections in humans.
本发明涉及发现某些含有尿嘧啶碱基的P-L-二氧兰核苷类似物,尤其是含有5-卤代尿嘧啶碱基的类似物,对于Epstein-Barr病毒(EBV)、水痘带状疱疹病毒(VZV)和人类疱疹病毒8(HV-8)表现出意外的高活性。特别是,本发明的化合物在对宿主细胞(即动物或人体组织)的毒性非常低的情况下,显示出对病毒复制(病毒生长)的强效抑制。这些化合物对于治疗人类EBV、VZV和HV-8感染非常有用。
