Extensive research has gone into the area of metalloproteinases since the introduction of captopril as an inhibitor of angiotensin converting enzyme for the treatment of hypertension. Matrix metalloproteinases were favorite targets of pharmaceutical companies, with over 2,000 patents issued. Many of the MMPs are required for normal physiological processes such as bone growth, tissue remodeling, morphogenesis and Read More

There is a great unmet medical need in the area of cancer treatment. A potential therapeutic target for intervention in cancer is ADAM10. ADAM10 is a disintegrin-metalloproteinase that processes membrane bound proteins from the cell surface to yield soluble forms. Pharmaceutical companies are actively seeking out inhibitors of ADAM10 for treatments in cancer as the enzyme is known to release the ErbB receptor, HER2/ErbB Read More

Multi-drug resistant (MDR), pathogenic Gram-negative bacteria pose a serious health threat, and novel antibiotic targets must be identified to combat MDR infections. One promising target is the zinc-dependent metalloamidase UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase (LpxC), which catalyzes the committed step of lipid A (endotoxin) biosynthesis. LpxC is an essential, single copy gene that is Read More

Loss of aggrecan from articular cartilage is an early and critical event in the pathogenesis of osteoarthritis (OA) and is enzymatically mediated by aggrecanase activity. Since the discovery of aggrecanase-1 (ADAMTS-4) and aggrecanase- 2 (ADAMTS-5), both members of the “a disintegrin and metalloproteinase with thrombospondin motif” family of proteinases, other members of the family have been reported to have aggreca Read More

Anthrax is caused by infection with Bacillus anthracis, a spore forming, rod-shaped, encapsulated gram positive bacteria. The disease manifests itself in distinct ways depending on the route of entry of infective bacterial spores: cutaneous, inhalational, and gastrointestinal. Though rare in humans, inhalational anthrax has become a major concern due to the capacity for spores to be weaponized. The limited success of anti Read More

Matrix metalloproteinases (MMPs) are a large family of proteolytic enzymes involved in an array of physiological and pathological processes from development, morphogenesis, reproduction, wound healing, and aging to inflammation, angiogenesis, neurological disorders, and cancer cell invasion and metastasis. The imbalance between MMP activity and the inhibitory action of tissue inhibitors of metalloproteinases (TIMPs) Read More

The role of matrix metalloproteinases in disease has been investigated over the last two decades. A focus on this family of proteases is particularly emphasized in two major arthritides in humans, osteoarthritis and rheumatoid arthritis. Early work described the presence of multiple MMP family members in the joint of the disease state and recent advances in the development of new knockout mice and disease models have allo Read More
