lysine in the P2 position, which allows the closing of the cycle on its side chain. These molecules show a free N-terminus, necessary for binding to the CD26 catalytic site, and a latent quinoniminium methide electrophile, responsible for inactivation. Treatment of c[alphaZ-Lys-Pro-Aba-(6-CH2-OC6H5)-Glyn], obtained by peptide synthesis in solution, with R2S/TFA simutaneously cleaved the Z protecting group
