| Description: | Human recombinant active MMP-2 and MMP-7, and the catalytic domains of MMP-3 and MMP-14/MT1-MMP were purchased from EMD Chemicals, Inc. (San Diego, Calif., USA); human recombinant catalytic domains of MMP-1, MMP-8, and MMP-9 were purchased from Enzo Life Sciences, Inc. (Farmingdale, N.Y., USA); human recombinant active ADAM9 and ADAM10 were purchased from R&D Systems (Minneapolis, Minn., USA). Fluorogenic substrates MOCAc-Pro-Leu-Gly-Leu-A2pr(Dnp)-Ala-Arg-NH2 (for MMP-2, MMP-7, MMP-9 and MMP-14) and MOCAc-Arg-Pro-Lys-Pro-Val-Glu-Nva-Trp-Arg-Lys(Dnp)-NH2 (for MMP-3) were purchased from Peptides International (Louisville, Ky., USA); Mca-KPLGL-Dpa-AR-NH2 (for MMP-1, MMP-8 and ADAM10) and Mca-PLAQAV-Dpa-RSSSR-NH2 (for ADAM9) were purchased from R&D Systems (Minneapolis, Minn., USA). The Km values for MMP-2, MMP-9 and MMP-14 were the same as previously reported by Gooyit et al. ((2013) J. Med. Chem. 56(20):8139-8150). Inhibitor stock solutions (10 mM) were prepared freshly in DMSO before enzyme inhibition assays. We followed the same methodology for enzyme inhibition studies as reported before by Page-McCaw et al. ((2007) Nat Rev Mol Cell Biol 8(3):221-233). Enzyme inhibition studies were carried out using a Cary Eclipse fluorescence spectrophotometer (Varian, Walnut Creek, Calif., USA). Compound 1 was stable in the buffers used in the kinetic assays. |
