  • Publication number: 20130166268
    Abstract: The present invention includes a crystal comprising a complex of the pro form of a matrix metalloprotease (proMMP) and a small-molecule allosteric processing inhibitor that inhibits that activation of the proMMP, methods for identifying small-molecule allosteric processing inhibitors that inhibit the activation of a proMMP, and methods of treatment using small-molecule allosteric processing inhibitors that inhibit the activation of a proMMP. The present invention relates to the crystal structure of a complex of proMMP9 bound to a small-molecule allosteric processing inhibitor that inhibits activation of proMMP9. The invention further relates to the use of the methods and the crystal and related structural information for designing, selecting and/or optimizing small-molecule allosteric processing inhibitors that inhibit activation of proMMP9 and proMMP9 homologues.
