We are using biochemical and biophysical tools for drug discovery against the Human Immunodeficiency Virus fusion mechanism. Drugs in this class have the potential to prevent the infection of T-cells by invading virus, and are so far limited to peptides that have poor pharmaceutical and bioavailability profiles. We are using techniques such as bio-inorganic chemistry, fluorescence, NMR spectroscopy and solid state biosensors to develop methodology allowing detection of small molecules targeting the viral fusion domain. Such compounds have the potential to be developed into effective drugs.
Current research includes the development of assays for the detection, evaluation and development of fusion inhibitors against HIV. Methodology includes the use of a fluorescence assay to detect inhibitors binding to the HIV-1 envelope protein gp41, which is responsible for viral fusion. NMR studies have been designed for structural elucidation of bound low molecular weight gp41 inhibitors. A solid-state (biosensor) assay utilizing an electrochemical quartz crystal microbalance has been developed. We are also actively engaged in synthetic chemistry and computational chemistry for rational drug design. Currently three classes of compounds are being investigated: 1) compounds randomly chosen from screening of a large diverse library; 2) Compounds selected from focused combinatorial libraries of peptidomimetics which mimic the natural interaction; 3) Rationally designed compounds based on structure-based drug discovery. Application of the technology to the trimeric domain of other Class 1 viruses, in particular Influenza virus, as well as other types of pathogens, eg. Tuberculosis, is being considered.
