Cordycepin, a natural derivative of adenosine from , can inhibit the replication of the dengue virus (DENV). Here, we investigated its antiviral and anti-inflammatory effects in DENV infected cells. Cordycepin significantly inhibited DENV-2 infection, virion production, and viral protein synthesis. It also reduced DENV-induced cytokine/chemokine production, including RANTES, IP-10, IL-6, and TNF-α. Mechanistically, cordycepin targeted the DENV NS5 protein, suppressing RANTES expression and hindering viral replication. Additionally, it inhibited the NF-κB pathway, leading to reduced nuclear translocation and signaling deactivation. PCR array analysis revealed cordycepin's suppression of 46 genes associated with DENV-induced inflammation. These findings highlight cordycepin's dual potential as an antiviral and anti-inflammatory agent against DENV, making it as a promising candidate for dengue treatment, targeting both viral and host factors.
虫草素是腺苷的一种天然衍生物，能够抑制登革病毒（DENV）的复制。在此，我们研究了其在DENV感染细胞中的抗病毒和抗炎作用。虫草素显著抑制DENV-2感染、病毒粒子产生和病毒蛋白合成。它还减少了DENV诱导的细胞因子/趋化因子产生，包括调节激活正常T细胞表达和分泌的趋化因子（RANTES）、干扰素诱导蛋白10（IP-10）、白细胞介素-6（IL-6）和肿瘤坏死因子-α（TNF-α）。从机制上讲，虫草素靶向DENV NS5蛋白，抑制RANTES表达并阻碍病毒复制。此外，它抑制核因子κB（NF-κB）途径，导致核转位减少和信号失活。聚合酶链反应（PCR）芯片分析显示虫草素抑制了46个与DENV诱导的炎症相关的基因。这些发现突出了虫草素作为一种针对DENV的抗病毒和抗炎药物的双重潜力，使其成为一种有前途的登革热治疗候选药物，可同时针对病毒和宿主因素。
