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.

A series of phosphonamide-based hydroxamate derivatives were synthesized, and the inhibitory activities were evaluated against various metalloproteinases in order to clarify its selectivity profile. Among the four diastereomeric isomers resulting from the chirality at the C-3 and P atoms, the compound with a (R,R)-configuration both at the C-3 position and the phosphorus atom was found to be potently active, while the other diastereomeric isomers were almost inactive. A number of (R,R)-compounds synthesized here exhibited broad spectrum activities with nanomolar K(i) values against MMP-1, -3, -9, and TACE and also showed nanomolar IC(50) values against HB-EGF shedding in a cell-based inhibition assay. The modeling study using X-ray structure of MMP-3 suggested the possible binding mode of the phosphonamide-based inhibitors.
