  • Patent number: 7205285
    Abstract: The invention provides novel ?-lactamase inhibitors, which are structurally unrelated to the natural product and semi-synthetic ?-lactamase inhibitors presently available, and which do not possess a ?-lactam pharmacophore. These new inhibitors are fully synthetic, allowing ready access to a wide variety of structurally related analogs. Certain embodiments of these new inhibitors also bind bacterial DD-peptidases, thus potentially acting both as ?-lactamase inhibitors and as antibiotics.
