Protein p53 is a key player in mitochondrial mediated apoptotic cell death and excess p53 activity has been implicated in many disease states such athrosclerosis, diabetes, osteoarthritis, Alzheimer's disease, Parkinson's disease, Huntington's disease, AIDS, P. falciparum and S. typhimurium infections. Thus, chemical inhibitors of p53 activation might prove effective in suppressing diseases associated with excess p53 activity. Read More

Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is a scavenger receptor that primarily binds and regulates oxidized low-density lipoprotein (LDL). Expression of LOX-1 is regulated by a feed-forward system stimulated by oxidized LDL (oxLDL), a major component of atherosclerosis. LOX-1 is a homodimer with a reactive backbone that can bind to a host of different ligands, including small molecules, a Read More

Lipopolysaccharides (LPS, endotoxins) belong to the strongest elicitors of the mammalian immune system due to the induction of a series of cytokines such as tumor-necrosis-factor-α (TNFα) in immunocompetent cells like mononuclear cells. Since the effects of LPS on human health may be pathologically at too high concentrations (e.g., septic shock syndrome), it is of uttermost importance to have a reliable assay for mea Read More

CYP2D6 accounts for only a small percentage of total hepatic CYPs (<2%), but it metabolizes ∼25% of clinically used drugs (>100) with significant polymorphisms. A number of drugs acting on the central nervous system and cardiovascular system are substantially metabolized by CYP2D6. The enzyme also utilizes hydroxytryptamines and neurosteroids as endogenous substrates. In addition, CYP2D6 metabolizes procarcinogens Read More
