We report on a series of potent and selective dipeptide fluoromethyl ketone inhibitors of recombinant human calpain I. Compound 4f, having a tetrahydroisoquinoline containing urea motif as N-terminus capping group, is the most potent member (k(obs)/I = 276,000 M(-1) s(-1)) of this class. This compound was shown to prefer calpain I by >36-fold and approximately 4-fold over the related cysteine proteases, cathepsin B and cathepsin L, respectively. Copyright (C) 1996 Elsevier Science Ltd
