Alzheimer's disease is an age-related neurodegenerative disease which causes global loss of cognitive function. Drug treatment for Alzheimer's disease has been limited to agents that ameliorate behavioral symptoms but these agents are without effect on disease progression. Rational drug design for the treatment of Alzheimer's disease now seems possible. As a result of major advances in medical research in this area, kno Read More

New treatments for HCV (Hepatitis C virus) infections are likely to arise from inhibition of the essential, virally-encoded enzymes. These targets include the serine protease required for processing of the HCV polyprotein. The protease constitutes one functional domain of the bifunctional HCV NS3 (non-structural protein 3). Here, insights regarding the NS3 structure and recently synthesized NS3 inhibitors are reviewed. Interesti Read More

Human urokinase-type plasminogen activator (uPA or uPA) has been implicated in the regulation and control of basement membrane and interstitial protein degradation. Since Urokinase plays a role in tissue remodeling, it may be responsible, in part, for the disease progression of cancer. Inhibitors of urokinase may then be useful in the treatment of cancer by retarding tumor growth and metastasis. Urokinase is a Read More

There is an increasing need to rapidly determine the specificity of proteases that potentially play a role in human and animal disease. Substrates for novel proteases can be discovered by testing standard protease substrates such as oxidized insulin B-chain, by screening commercially available substrates for other proteases, or by preparing derivatives of known biological targets. The relative importance of each substr Read More
