Antivirus definition at Dictionary.com, a free online dictionary with pronunciation, synonyms and translation. In this article we will discuss about the strategies and types of antiviral drugs.. Strategies of Antiviral Drugs: Antibiotics which have revolutionized the control of diseases caused by bacteria and some other pathogenic agents are totally ineffective against viruses, because the viruses do not have a cell and they are heavily dependent on the host cell for multiplication. PKR expression is induced upon activation by IFN and becomes autophosphorylated and then phosphorylates initiation factor 2 (eIF2), resulting in an inhibition of protein synthesis.
