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.
描述了获得三取代吡唑并[3,4-d]嘧啶14-17的有用途径。后来将它们与烷基化剂18–20(如ACV,HBG和iso-DHPG)偶联,脱保护后得到所需的酰基核苷33–44。评估了几乎所有新化合物对培养物中各种DNA病毒复制的抑制作用。
