title: Peptidyl aldehyde inhibitors of calpain incorporating P2-proline mimetics.
abstract: Four new peptidyl aldehydes bearing proline mimetics at the P(2)-position were synthesized and studied as inhibitors of calpain I, cathepsin B, and selected serine proteases. The ring size of the P(2)-constraining residue influenced the inhibitory potency and selectivity of the compounds for calpain I compared to the other proteases.
