Bioinorganic Chemistry: Various aspects of the chemistry, biochemistry and cell biology of transition metal complexes of Cr and Ni (occupational cancers), V and Cr(III) (anti-diabetic agents), Ga and Ru (anti-cancer agents), Fe (heme proteins), and Cu (anti-inflammatory drugs) have been studied. A wide variety of spectroscopic, structural, biochemical and cell biology techniques have been employed to understand better the bioinorganic chemistry of these transition metals and to develop protective dietary protocols for metal induced cancers and to develop new potential pharmaceuticals.
Biospectroscopy, Imaging, and Mapping: Complementary imaging and mapping using X-ray absorption (synchrotron-induced X-ray emission, X-ray absorption near edge-structure), proton-induced X-ray emission, vibrational (FTIR and Raman), phase-contrast (X-ray and visible), fluorescence, and other spectromicroscopies are being used to study changes in biodistributions and concentrations of elements and biochemicals in cells and tissues as a result of diseases processes and their treatment. Biospectroscopy is also being used to develop new disease diagnostics. Diseases being studied include, cancer, diabetes, graft-versus host disease, malaria, meningitis, Parkinson's disease and other bacterial and viral infections.
Physical Inorganic Chemistry: A large range of spectroscopic, electrochemical and structural techniques has been used to gain fundamental insights into chemical reactivity of transition metal complexes and solvation effects on chemical reactivity. This also includes detailed studies of fullerenes and fullerides.
Research Projects
Biospectroscopy, medicinal inorganic chemistry, and molecular and cell biology will be used to understand the mode of action of existing drugs, the design of new drugs and to learn more about normal physiological and disease processes at a molecular and cellular level. Projects will centre on metal-based anti-cancer and anti-diabetic drugs, the active sites of heme proteins, or the use of biospectroscopy in disease diagnosis.
Biochemistry of Cr, Mo and V Anti-Diabetic Drugs and Supplements
We have amassed evidence to implicate potentially carcinogenic Cr(VI/V) complexes as the active forms of Cr dietary supplements that are widely consumed for fat reduction and the treatment and prevention of diabetes. We are using similar techniques to those used in the Cr studies to unravel the biochemistry of V and Mo supplements that are also anti-diabetics. The studies are aimed at producing safer and more efficacious treatments for the prevention and treatment of diabetes. These projects will include studies of the interactions of the complexes with biomolecules and cells using various spectroscopic techniques, including microprobes (X-ray, Raman, FTIR and fluorescence).
Anti-Cancer Drugs
The anti-cancer properties of Ru complexes will be studied, since Ru complexes are one of few classes that have strong anti-metastatic activities. Investigations will involve studies on the ability of the Ru complexes to bind to blood proteins, extracellular matrices, the cell surface, and intracellular targets in order to bring about their activities. Separate studies on Ga, V (with Dr. A. Levina) and Rh anti-cancer drugs (with Drs. R. Baker and A. Levina) have also been shown considerable promise. A project focused on any one of these classes could include a combination of synthetic chemistry, biospectroscopy, and biochemical and cell biology assays.
Heme Proteins
Heme proteins have diverse biological roles and NO-heme adducts have been implicated in many of these roles. This project involves studies into the Raman and X-ray absorption spectroscopies of heme proteins in order to understand features of their chemistry, structures, and functions. Studies will involve investigations of isolated proteins that use the binding of NO or other small molecules in signal processes, the immune system, and/or for vasodilation, or the role of such proteins in cardiovascular disease. Research into the structures of intracellular heme proteins within cells is also possible.
Vibrational Spectroscopic Studies for Studies on Disease Processes and Diagnosis
Projects will involve the use of IR and Raman techniques to diagnose various diseases and to understand disease progression at the biochemical level. The techniques rely on the ability of vibrational spectroscopic techniques to differentiate changes in amounts and distributions of biochemicals. Research could concentrate on cancer, malaria, or cardiovascular disease, in collaboration with colleagues in a number of hospitals and medical institutes.
