Borna disease virus (BDV) causes neurological diseases in a variety of warm-blooded animal species, possibly including humans. To date, there is no effective treatment against BDV infection. Recently, we reported on the antiviral activity of 1-beta-D-arabinofuranosylcytosine (Ara-C). However, Ara-C's cytotoxic side effects are a major obstacle for its therapeutic use. Herein, we demonstrate that the nucleoside analog 2'-fluoro-2'-deoxycytidine (2'-FdC) exhibits potent antiviral activity against BDV. Importantly, 2'-FdC-associated cytotoxicity is negligible, indicating 2'-FdC as an excellent candidate for the development of antiviral therapy against BDV.
博尔纳病病毒(BDV)可在多种温血动物物种中引发神经疾病,人类可能也包括在内。迄今为止,尚无针对BDV感染的有效治疗方法。最近,我们报道了1-β-D-阿拉伯呋喃糖基胞嘧啶(Ara-C)的抗病毒活性。然而,Ara-C的细胞毒性副作用是其治疗应用的主要障碍。在此,我们证明核苷类似物2'-氟-2'-脱氧胞苷(2'-FdC)对BDV具有强大的抗病毒活性。重要的是,2'-FdC相关的细胞毒性可忽略不计,这表明2'-FdC是开发抗BDV抗病毒疗法的极佳候选药物。
