Prodrugs of carbamate inhibitors of IMPDH

Abstract

The present invention relates to novel compounds, methods of preparing these compounds, and pharmaceutical compositions comprising these compounds. These compounds are carbamate prodrugs that convert to active inhibitors of the IMPDH enzyme in vivo. The compounds and pharmaceutical compositions of this invention are particularly well suited for activation and subsequent inhibition of the IMPDH enzyme activity. Consequently, these prodrugs may be advantageously used as therapeutic agents for IMPDH mediated processes. This invention also relates to methods for inhibiting the activity of IMPDH using the compounds and compositions of this invention.
