As a continuation of our SAR studies of dipeptidyl aspartyl-fmk as caspase inhibitors, we explored the replacement of the P(2) aminoacid by a 2-aminoaryl acid or other non-natural aminoacids. Several of these compounds, such as 6l and 6p, were found to have good activities with inhibition potencies of around 100 nM in a caspase-3 enzyme assay. EP1113, Z-Val-(2-aminobenzoyl)-Asp-fmk (9b), is identified
