  • Nucleoside 5'-monophosphate mimics and their prodrugs
    Publication number: 20040023901
    Abstract: The present invention relates to novel nucleoside 5′-monophosphate mimics, which contain novel nucleoside bases and phosphate moiety mimics optionally having sugar-modifications. The nucleotide mimics of the present invention, in a form of a pharmaceutically acceptable salt, a pharmaceutically acceptable prodrug, or a pharmaceutical formulation, are useful as antiviral, antimicrobial, anticancer, and immunomodulatory agents. The present invention provides a method for the treatment of viral infections, microbial infections, and proliferative disorders. The present invention also relates to pharmaceutical compositions comprising the compounds of the present invention optionally in combination with other pharmaceutically active agents.
