Synthesis and evaluation of tricyclic pyrrolopyrimidinones as dipeptide mimetics: inhibition of interleukin-1beta-converting enzyme

The application of a tricyclic pyrrolopyrimidinone scaffold for the synthesis of peptidomimetic inhibitors of interleukin-1beta-converting enzyme (ICE) is reported. The synthesis of the tricyclic scaffold and conversion of it to a variety of target ICE inhibitors were accomplished in 4-5 steps. In v...

Description
Summary:The application of a tricyclic pyrrolopyrimidinone scaffold for the synthesis of peptidomimetic inhibitors of interleukin-1beta-converting enzyme (ICE) is reported. The synthesis of the tricyclic scaffold and conversion of it to a variety of target ICE inhibitors were accomplished in 4-5 steps. In vitro biological evaluation of the tricyclic pyrrolopyrimidinones revealed fair to good ICE inhibitors, with the most active compound exhibiting an IC50 of 14 nM in a caspase-1 enzyme binding assay.
