  • Publication number: 20160346247
    Abstract: The invention provides compounds, compositions, and methods for the treatment of diseases, disorders, or conditions that are modulated by matrix metalloproteinases (MMPs). The disease, disorder, or condition can include, for example, stroke, neurological disorders, or ophthalmological disorders. The treatment can include administering a compound or composition described herein, thereby providing a prodrug compound that metabolizes to an active MMP inhibitor in vivo. The MMP inhibition can be selective inhibition, for example, selective inhibition of MMP-2, MMP-9, and/or MMP-14. Thus, the invention provides non-mutagenic prodrug compounds of the formulas described herein that result in the inhibition of MMPs upon in vivo administration.

  • Publication number: 20160031832
    Abstract: A new class of antibiotics effective against methicillin-resistant Staphylococcus aureus (MRSA) is disclosed. Compounds of this class can impair cell-wall biosynthesis by binding to both the allosteric and the catalytic domains of penicillin-binding protein (PBP) 2a. This class of antibiotics holds promise in reversing obsolescence of staphylococcal PBPs as important targets for antibiotics. Embodiments of the invention thus provide novel antibacterial compounds that target penicillin-binding proteins and/or other important cellular targets. Methods for inhibiting the growth and/or replication of bacteria using the compounds described herein are also provided. Various embodiments exhibit activity against gram positive bacteria, including drug-resistant strains of Staphylococcus aureus.

  • Publication number: 20130064878
    Abstract: The invention provides a method of accelerating the healing process of a skin or subdermal wound. The method can include administering to a mammal afflicted with a skin or subdermal wound an effective amount of a gelatinase inhibitor, or a pharmaceutically acceptable salt thereof, wherein the gelatinase inhibitor is effective to accelerate the healing process of the skin wound. The method is particularly effective when the mammal is suffering from diabetes. The gelatinase inhibitor can be topically administered, for example, in the form of a cream, gel, lotion, ointment, salve, or solution.
