Analysis of subpocket selectivity and identification of potent selective inhibitors for matriptase and matriptase-2

J Med Chem. 2014 Dec 11;57(23):10198-204. doi: 10.1021/jm5015633. Epub 2014 Nov 21.

Abstract

We studied the factors affecting the selectivity of peptidomimetic inhibitors of the highly homologous proteases matriptase and matriptase-2 across subpockets using docking simulations. We observed that the farther away a subpocket is located from the catalytic site, the more pronounced its role in selectivity. As a result of our exhaustive virtual screening, we biochemically validated novel potent and selective inhibitors of both enzymes.
