Cordycepin exhibits both antiviral and anti-inflammatory effects against dengue virus infection.

ABSTRACT: Cordycepin, a natural derivative of adenosine from Cordyceps militaris, 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 co
