Synthesis and antiviral evaluation of bis(POM) prodrugs of (E)-[4′-phosphono-but-2′-en-1′-yl]purine nucleosides
摘要:
Seventeen hitherto unknown bis(POM) prodrugs of novel (E)-[4'-phosphono-but-2'-en-1'-yl]purine nucleosides were prepared in a straight approach and at good yields. Those compounds were synthesized by the reaction of purine nucleobases directly with the phosphonate synthon 3 bearing POM biolabile groups under Mitsunobu conditions. All obtained compounds were evaluated for their antiviral activities against a large number of DNA and RNA viruses including herpes simplex viruses 1 and 2, varicella zoster virus, Feline herpes virus, human cytomegalovirus, HIV-1 and HIV-2. Among these molecules, some of them exhibit anti-VZV and anti-HIV activity at submicromolar concentrations. This class of compound will be of further interest for lead optimization as anti-infectious agents. (C) 2012 Elsevier Masson SAS. All rights reserved.

A simple three-step method for the solution-phase combinatorial synthesis of 2,6,9-trisubstituted purines from 2,6-dichloropurine is described. The synthesis exploits the use of resin capture to remove excess reagent used in the final step. (C) 1998 Elsevier Science Ltd. All rights reserved.
