Novel non-nucleoside human cytomegalovirus inhibitors based upon TSAO nucleoside derivatives: structure-activity relationships

Nucleosides Nucleotides Nucleic Acids. 2007;26(6-7):625-8. doi: 10.1080/15257770701490431.

Abstract

TSAO derivatives are a unique group of potent and highly specific inhibitors of HIV-1 replication. We have recently reported 4''-ureido TSAO derivatives that are devoid of anti-HIV-1 activity, but inhibit human cytomegalovirus with an activity comparable to that of Ganciclovir. We herein report the synthesis and biological evaluation of novel 4''-ureido TSAO derivatives in order to evaluate the structural features required for anti-HCMV activity. Interestingly, these studies revealed that the compounds may inhibit HCMV at the DNA polymerase step via a non-nucleoside mechanism.
