COLLAGENASE-3 (MMP-13) COMPLEXED TO A SULPHONE-BASED HYDROXAMIC ACID

Overview

The X-ray crystal structures of the catalytic domain of human, collagenase-3 (MMP-13) and collagenase-1 (MMP-1) with bound inhibitors, provides a basis for understanding the selectivity profile of a novel, series of matrix metalloprotease (MMP) inhibitors. Differences in the, relative size and shape of the MMP S1' pockets suggest that this pocket is, a critical determinant of MMP inhibitor selectivity. The collagenase-3 S1', pocket is long and open, easily accommodating large P1' groups, such as, diphenylether. In contrast, the collagenase-1 S1' pocket must undergo a, conformational change to accommodate comparable P1' groups. The, selectivity of the diphenylether series of inhibitors for collagenase-3 is, largely determined by their affinity for the preformed S1' pocket of, collagenase-3, as compared to the induced fit in collagenase-1.
