  Design, synthesis, and structure–activity relationships of pyrazolo[3,4-d]pyrimidines: a novel class of potent enterovirus inhibitors

  摘要：

  A series of pyrazolo[3,4-d]pyrimidines were synthesized. and their antiviral activity was evaluated in a plaque reduction assay. It is very interesting that this class of compounds provide remarkable evidence that they are very specific for human enteroviruses, in particular, coxsackieviruses. Some derivatives proved to be highly effective in inhibiting enterovirus replication at nanomolar concentrations. SAR studies revealed that the phenyl group at the N-I position and the hydrophobic diarylmethyl group at the piperazine largely influenced the in vitro antienteroviral activity of this new class of potent antiviral agents. It was found that the pyrazolo[3,4-d]pyrimidines with a thiophene substituent, such as compounds 20 24, in general exhibited high activity against coxsackievirus B3 (IC50 = 0.063-0.089 muM) and moderate activity against enterovirus 71 (IC50 = 0.32-0.65 muM) with no apparent cytotoxic effect toward RD (rhabdomyosarcoma) cell lines (CC50>25 muM).
