  Matrix Metalloproteinase Inhibitors:  A Structure−Activity Study

  摘要：

  Modifications around the dipeptide-mimetic core of a hydroxamic acid based matrix metalloproteinase inhibitor were studied. These variations incorporated a variety of natural, unnatural, and synthetic amino acids in addition to modifications of the P1' and P3' substituents. The results of this study indicate the following structural requirements: (1) Two key hydrogen bonds must be present between the enzyme and potent substrates. (2) Potent inhibitors must possess strong zinc-binding functionalities. (3) The potential importance of the hydrophobic group at position R3 as illustrated by its ability to impart greater relative potency against stromelysin when larger hydrophobic groups are used. (4) Requirements surrounding the nature of the amino acid appear to be more restrictive for stromelysin than for neutrophil collagenase, 72 kDa gelatinase, and 92 kDa gelatinase. These requirements may involve planar fused-ring aryl systems and possibly hydrogen-bonding capabilities.

  Provided are compositions and methods for treating lung or respiratory disorders or conditions characterized by airflow obstruction or limitation, or a symptom thereof (e.g., asthma, rhinitis, allergic rhinitis, and chronic obstructive pulmonary disease (COPD) and COPD-associated conditions (e.g., bronchitis, emphysema, asthma), emphysema, pneumonia, bronchitis, influenza, SARS, tuberculosis, and whooping cough (pertussis), and the like) in a subject in need thereof by administering a therapeutic composition comprising at least one electrokinetically altered fluid (gas-enriched (e.g., oxygen-enriched) electrokinetic fluids) comprising an ionic aqueous solution of charge-stabilized oxygen-containing nanostructures as disclosed herein. In certain aspects, the methods comprise regulating intracellular signal transduction by modulation of at least one of cellular membranes, membrane potential, membrane proteins (e.g., membrane receptors, (e.g., to G protein coupled receptors, and intercellular junctions)). Additional aspects include therapeutic compositions, and combination treatment methods comprising administration of electrokinetically generated fluid in combination with at least one additional therapeutic agent.

  Provided are electrokinetically-altered fluids (gas-enriched electrokinetic fluids) comprising an ionic aqueous solution of charge-stabilized oxygen-containing nanostructures in an amount sufficient to provide modulation of at least one of cellular membrane potential and cellular membrane conductivity, and therapeutic compositions and methods for use in treating inflammatory neurodegenerative condition or disease or at least one symptom thereof. The electrokinetically-altered fluids or therapeutic compositions and methods include electrokinetically-altered ioinic aqueous fluids optionally in combination with other therapeutic agents. Particular aspects provide for regulating or modulating intracellular signal transduction associated with said inflammatory responses by modulation of at least one of cellular membranes, membrane potential, membrane proteins such as membrane receptors, including but not limited to G-Protein Coupled Receptors (GPCR), and intercellular junctions (e.g., tight junctions, gap junctions, zona adherins and desmasomes). Other embodiments include particular routes of administration or formulations for the electrokinetically-altered fluids (e.g., electrokinetically-altered gas-enriched fluids and solutions) and therapeutic compositions.
