Inhibition of Matrix Metalloproteinases by N-carboxyalkyl Peptides Containing Extended Alkyl Residues at P1'

A series of N-carboxyalkyl peptides were prepared to test their inhibitory activity against human stromelysin (MMP-3), collagenase (MMP-1), and gelatinase A (MMP-2). Linear alkyl and ω-aminoalkyl residues were employed as replacements for a phenethyl group yielding inhibitors with in vitro activities comparable to their corresponding aromatic analogs.
