title: Synthesis and antiviral activity of some C2-, C4-, and C6-substituted pyrazolo[3,4-D]pyrimidine acyclonucleosides with the alkylating chains of ACV, HBG, and ISO-DHPG.
abstract: A useful route to obtain trisubstituted pyrazolo[3,4-d]pyrimidines 14-17 is described. Those later were coupled with the alkylating agents 18-20 as in ACV, HBG, and iso-DHPG to give, after deprotection, the desired acylonucleosides 33-44. Almost all of the new compounds were evaluated for their inhibitory effects against the replication of various DNA viruses in culture.
