Abstract [en]
Herpes simplex virus type-1 (HSV1) exploits cellular machinery for its own replicative advantage. Current treatment modalities against HSV1 cause toxicity and drug resistance issues. In the search for alternative forms of treatment, we have uncovered a small molecule, BX795, as a candidate drug with strong antiviral potential owing to its multitargeted mode of action. In this study, we show that in addition to a previously known mechanism of action, BX795 can directly interact with the proviral host factor protein kinase C (PKC) in silico. When administered to HSV1 or mock infected human corneal epithelial (HCE) cells, BX795 significantly reduces the protein level and perinuclear localization of proviral PKC-alpha and PKC-zeta isoforms. This activity closely mimics that of a known PKC inhibitor, Bisindolylmaleimide I (BIM I), which also inhibits viral replication. Taken together our studies demonstrate a previously unknown mechanism by which BX795 exerts its antiviral potential.
