title: Nucleic acid related compounds. 47. Synthesis and biological activities of pyrimidine and purine "acyclic" nucleoside analogues.
abstract: Various acyclic, i.e., (2-hydroxyethoxy)methyl and (2-acetoxyethoxy)methyl, analogues of pyrimidine and purine nucleosides have been prepared and evaluated for their antiviral, antimetabolic, and cytotoxic properties. All of the pyrimidine analogues, including (E)-5-(2-bromovinyl)-1-[(2-hydroxyethoxy)methyl]uracil (12) and its O-acetyl derivative (13), were virtually devoid of antiviral, cytotoxic, and antimetabolic activities. However, several of the 8-substituted derivatives of 9-[(2-hydroxyethoxy)methyl]guanine (acyclovir) had higher antiviral specificity in vitro than the parent drug. The 8-methyl-, 8-amino-, 8-bromo-, and 8-iodoacyclovir derivatives have activities worthy of further investigation.
