Abstract
A new series of hydroxamic acid-based matrix metalloproteinase (MMP) inhibitors containing a unique phosphinamide motif derived from D-amino acid was designed, synthesized, and tested for enzyme inhibition. Compounds with an R configuration at phosphorus were found to be potent MMP inhibitors while molecules with the S configuration were almost inactive. Structure-activity relationship studies of the series led to the discovery of the potent inhibitor 16 with IC50 = 20.5 nM and 24.4 nM against fibroblast collagenase (MMP-1) and stromelysin (MMP-3), respectively. The binding mode of this novel phosphinamide-based series of MMP inhibitors was established based on X-ray crystallography of the complex of stromelysin and 16.
