Design and Synthesis of Malonic Acid-Based Inhibitors of Human Neutrophil Collagenase (MMP8)
摘要:
For most of the known synthetic inhibitors of matrix metalloproteinases (MMPs), a substrate-like binding mode was postulated on the basis of X-ray crystallographic structures of MMP/inhibitor complexes. Conversely, the malonic acid-based inhibitor (2R,S)-HONH-CO-CH(i-Bu)-CO-Ala-Gly-NH2 was found to bind in a surprisingly different manner. Using this compound as a new lead structure, the interaction sites with human neutrophil collagenase (MMP8) were optimized with a series of iteratively designed analogues and with the help of X-ray structural analysis of selected inhibitors to finally produce low molecular weight nonpeptidic compounds of 500-1000-fold improved inhibitory potency.
