Mechanism of Antiviral Activity of 5-Ethyl-2′-Deoxyuridine

Abstract
5-Ethyl-2′-deoxyurldine (EDU) is phosphorylated to a much greater extent by herpes simplex virus (HSV)-infected Vero cells than by mock-infected cells. Within the infected cells, EDU is preferentially incorporated into viral DNA and more inhibitory to viral than cellular DNA synthesis
