Research in my laboratories seeks to identify, describe and solve biological problems through chemical means. Improved understanding of the molecular bases of various pathological and toxicological phenomena are regarded as milestones, with the design and successful development of novel chemical or biological therapeutics and diagnostic tools being the end-goals. A broad range of techniques are employed toward these ends, ranging from animal behavior studies, molecular biology, organic synthesis, rational drug design, biophysics, imaging and microscopy. A keen emphasis is placed on inculcating interdisciplinary research skills in laboratory personnel that would enable them to function as independent researchers.
Currently targeted areas are:
1. Oxidative stress – pathological and toxicological studies, chemoprevention, drug design.
Amyloidogenic peptides are established etiological agents of Alzheimer’s and Parkinson’s diseases. We have shown through biophysical and biochemical investigations that the food additive, 2,3-butanedione (diacetyl) is capable of inducing amyloid peptide misfolding in intact cells. Ongoing research seeks to define the relevance of this phenomenon in the intact animal.
The human body utilizes glutathione (1) as a primary cellular reductant. This thiol has been shown to be depleted in conditions of oxidative damage. Administration of 1 does not lead to the latter’s intact passage to the site of action due to metabolic breakdown by ᵞ-glutamyl transpeptidase. About five decades ago, Prof. Vince envisioned the creation of Ψ-GSH (2) as a means to bypass γ-glutamyl transpeptidase. We have now shown that 2 fulfills cardinal functions of 1, establishing it as a candidate for the treatment of a variety of conditions that involve deficiency of 1 and/or oxidative damage.
2. Drug transport – membrane transporters and their targeting.
The selective localization of membrane bound transport proteins renders attractive the latter’s exploitation for targeted drug delivery. Consequently, we are examining the distribution of membrane transporters in the body through various diagnostic probes and are designing small molecules that would be selectively uptaken by the transporter in question.
3. Imaging and diagnostic tool development.
We are seeking to validate imaging techniques for the identification and measurement of amyloidogenesis.
