The ketomethylene phenylalanal and alanal analogues of Cbz-Val-Phe-H and Cbz-Val-Ala-H have been prepared and the K(i) values versus chicken gizzard smooth muscle calpain were determined. The ketomethylene isosteres were significantly less potent than the corresponding dipeptide aldehydes, and this loss in activity is attributed to the absence of a critical interaction between the P1-P2 amide bond and the peptide binding region of calpain.
