  • Patent number: 9073829
    Abstract: The tetracycline class of antibiotics has played a major role in the treatment of infectious diseases for the past 50 years. However, the increased use of the tetracyclines in human and veterinary medicine has led to resistance among many organisms previously thought susceptible to tetracycline antibiotics. The recent development of a modular synthesis of tetracycline analogs through a chiral enone intermediate has allowed for the efficient synthesis of novel tetracycline analogs never prepared before. The present invention provides more efficient routes for preparing the enone intermediate and allows for substituents at positions 4a, 5, 5a, and 12a of the tetracycline ring system.

  • Publication number: 20140274971
    Abstract: Methods, devices and systems are disclosed for chemically bonding antibiotics to selected substrate materials which are not dissolved in normal physiological processes so that high local concentrations can be achieved during the inflammatory response. The antibiotics will remain permanently bonded to the substrate material until an infection occurs which releases the antibiotic in high concentrations to help control the infection. The high local concentrations may be much higher than systemic toxic levels, and can never reach toxic levels because the local dose is much less than needed to reach systemic toxicity if completely dissolved.

    Abstract: A combination of: a first tetracycline (TC) component; and a second component capable of releasing nitric oxide (NO) or a nitrate capable of mimicking NO effects in vivo (NO mimetic). The combinations of the invention advantageously act as more effective MMP modulators with selective reductions in circulating MMP-9 levels in-vivo and inhibitory effects on MMP-2 and MMP-9 levels in-vitro. The combinations of the invention also advantageously act as modulators of inflammation mediators. The co-existence of abnormalities of MMP enzymes and inflammation in many diseases make these characteristics advantageous. Therefore, the various combinations of the invention find utility in medical applications where MMPs and/or inflammation is implicated.
