  4′′-Benzoylureido-TSAO Derivatives as Potent and Selective Non-Nucleoside HCMV Inhibitors. Structure−Activity Relationship and Mechanism of Antiviral Action

  摘要：

  Analogues of the 4"-benzoyl-ureido-TSAO derivative (1) modified at different positions have been prepared and evaluated against wild-type strains of HCMV and murine cytomegalovirus (MCMV) in cell culture. In addition, the activity of the most active derivatives against several drug-resistant HCMV mutants has been determined. A stringent structure-antiviral activity relationship was observed for the 4"-benzoylureido-TSAO derivatives for which the concomitant presence of a highly lipophilic substituent at both 2'- and 5'-positions was required to fully preserve the antihuman cytomegalovirus efficacy. Time-of-addition studies and HCMV immediately early and early gene expression studies revealed a target at the time of viral DNA synthesis, although direct inhibition of HCMV-encoded DNA polymerase could not be observed in cell-free assays. Lack of cross-resistance against a broad variety of mutant HCMV strains points to an antiviral target that is different from those drugs that are currently approved for clinical use.
