About the Project
As a team of specialists with distinctive areas of expertise, we are interested in the isolation and characterisation of various venom proteins to determine their sequence-structure-function and evolutionary relationships. This will tremendously assist in the development of specific diagnostic tools for the detection of SBE from diverse species at different regions of the world. Furthermore, since the majority of venom components are proteins (mainly enzymes), we are using organic/synthetic chemistry approach to develop novel inhibitors or repurpose existing drugs in order to block the toxic activities of venom proteins. This will facilitate the development of a combination of chemical molecules and/or drugs that could collectively be used as a ‘universal antidote’ to treat SBE worldwide. We strongly believe that the chemical-based therapeutic approach is likely to possess numerous advantages over the traditionally used antivenom therapy. Therefore, this will be a ‘life-saving gift’ for people who live in remote regions of developing countries where SBE is an everyday threat for their lives.
Students who are interested in this project will have splendid opportunities to learn a broad spectrum of techniques in the field of pharmacology, toxicology, cell and molecular biology, biochemistry, pathology, structural biology, bioinformatics, biophysics and pharmaceutical chemistry.
