    • Compounds useful in the treatment of infection by an episomal DNA virus are identified by a method involving the steps of (1) providing a culture of mammalian or avian cells containing multiple copies of a recombinant viral extrachromosomal episome having an episomal maintenance element, the episomes being associated with a detectable label; (2) contacting the culture with a test molecule that inhibits the interaction between the episomal maintenance element on the episomes and at least one enzyme selected from a family of enzymes consisting of the poly-ADP ribose polymerase family, the poly-ADP glycosylase family, the telomerase family, the myb DNA binding family that interferes with telomeres, and the telomere repeat binding protein family; and (3) detecting the elimination of the episomes from the cells by detecting the presence of the detectable label in the medium of the culture. These compositions are useful in pharmaceutical compositions for treating an infection by an episomal DNA virus and in diagnostic kits.
    • 用于治疗附加型DNA病毒感染的化合物通过涉及以下步骤的方法进行鉴定:(1)提供哺乳动物或禽类细胞的培养物,所述哺乳动物或禽类细胞含有具有附加体维持元件的重组病毒染色体外附着物的多个拷贝,所述附加体是 与可检测标记物相关联; (2)使培养物与测试分子接触,所述测试分子抑制附加体上的附加型维持元件与选自由多聚ADP核糖聚合酶家族,多聚ADP糖基化酶家族组成的酶家族中的至少一种酶的相互作用, 端粒酶家族,干扰端粒的myb DNA结合家族和端粒重复结合蛋白家族; 和(3)通过检测培养基培养基中可检测标记的存在来检测来自细胞的附加体的消除。 这些组合物可用于治疗附加型DNA病毒感染的药物组合物和诊断试剂盒中。
