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.
An efficient synthesis of substituted cytosines and purines under focused microwave irradiation
A rapid nucleophilic displacement reaction of 6-chloropurine, 2-amino-6-chloropurine and 5-bromocytosine with various nucleophiles under focusedmicrowaveirradiation is described. Using this method, the desired products were obtained with the yields up to 99% in a short reaction time.
