埃博拉病毒(EBOV)感染是导致人类出血热的原因,死亡率很高。需要预防和治疗干预相结合的努力来应对高度可变的RNA病毒,其感染往往导致爆发。在这里,我们使用基于纳米荧光素酶的蛋白互补测定(NPCA)筛选了2 P2 I3 D化学文库,并分离出两种化合物,其破坏EBOV蛋白片段VP 35 IID与dsRNA结合蛋白PKR和PACT的N-末端的相互作用,所述dsRNA结合蛋白PKR和PACT分别参与IFN应答和/或固有免疫。这两种化合物抑制细胞培养物中的EBOV感染以及麻疹病毒(MV)的感染,而不依赖于IFN诱导。因此,我们提出这些化合物通过恢复由PACT驱动的固有免疫而具有抗病毒性。鉴于PACT在哺乳动物中高度保守,我们的数据支持在其他物种中进一步测试这些化合物,以及针对其他负义RNA病毒。
Infection with Ebola virus (EBOV) is responsible for hemorrhagic fever in humans with a high mortality rate. Combined efforts of prevention and therapeutic intervention are required to tackle highly variable RNA viruses, whose infections often lead to outbreaks. Here, we have screened the 2P2I3D chemical library using a nanoluciferase-based protein complementation assay (NPCA) and isolated two compounds that disrupt the interaction of the EBOV protein fragment VP35IID with the N-terminus of the dsRNA-binding proteins PKR and PACT, involved in IFN response and/or intrinsic immunity, respectively. The two compounds inhibited EBOV infection in cell culture as well as infection by measles virus (MV) independently of IFN induction. Consequently, we propose that the compounds are antiviral by restoring intrinsic immunity driven by PACT. Given that PACT is highly conserved across mammals, our data support further testing of the compounds in other species, as well as against other negative-sense RNA viruses.
