title: [4'-Thio-5-ethyl-2'-deoxyuridine 5'-phosphonates: synthesis and antiviral activity].
abstract: A number of new 5'-phosphonate derivatives of 4'-thio-5-ethyl-2'-deoxyuridine (TEDU) were synthesized. These compounds displayed a low cytotoxicity and, except for TEDU 5'-fluorophosphate, antiherpes activity similar to that of 9-[(2-hydroxyethoxy)methyl]guanine (acyclovir) and 9-(4-hydroxy-3-hydroxymethylbut-1-yl)guanine (pencyclovir). 5'-Ethoxycarbonylphosphonate and 5'-aminocarbonylphosphonate of TEDU were also found to suppress the reproduction of herpes simplex type 1 virus, which is resistant to acyclovir.
