A series of peptide mimetic aldehyde inhibitors of calpainI was prepared in which the P(2) and P(3) amino acids were replaced by substituted 3,4-dihydro-1,2-benzothiazine-3-carboxylate 1,1-dioxides. The effect of 2, 6, and 7-benzothiazine substituents and the P(1) amino acid was examined. Potency of these inhibitors, 15c-p, against humanrecombinantcalpainI is particularly dependent upon the 2-substituent
