2-Benzylthio-6-chloropurine is a synthetic nucleoside analogue that is an antiviral agent. It inhibits the synthesis of viral DNA by competitive inhibition of thymidine kinase, which is an enzyme necessary for the conversion of deoxyribonucleotides to their monophosphate form. 2-Benzylthio-6-chloropurine has been found to be effective against herpes simplex virus 1 and 2 (HSV1 and HSV2). The drug is also active against HIV, influenza A virus, and cytomegalovirus.
