Biographical details

Associate Professor Colin Duke has completed BSc studies in Botany and Chemistry majoring in Chemistry; BSc (Hons) and PhD studies on natural products isolation, identification and syntheses. Associate Professor Duke has extensive experience in the isolation, characterisation and activity evaluation of biologically-active substances from natural and synthetic sources for medicinal/nutritional uses and/or research tools. He has more than 100 publications in scientific literature to his name, spanning areas of synthetic chemistry, natural product chemistry, phytochemistry and mechanistic toxicology.

His studies carried out in the last 15 years at the Faculty of Pharmacy, University of Sydney include specific biological tests and screens used to detect biologically-active substances that are potentially useful for the treatment of viral, neurological, cardiovascular, cancer and other diseases.

Associate Professor Duke’s recent research is focused on new methods to efficiently identify potentially useful bioactive compounds from complex natural materials. Studies on propolis (a resinous material collected by honeybees from plants), has resulted in the identification of novel bioactive phenolic substances from Australian endemic plants. Structure-activity studies carried out with these and other substances have led to major industry-funded projects.

Research interests

  • Investigation of biologically-active substances from natural and synthetic sources for therapeutic purposes and/or research tools.
  • Use of specific biological tests and screens are used to detect biologically active substances potentially useful for the treatment of viral, neurological, cardiovascular, cancer and other diseases. Isolation of bioactive substances detected in extracts of selected plants, their identification and evaluation as potential drugs, lead substances for drug development and/or research tools.
  • Syntheses of biologically-active natural products and analogues, structure-activity relationships and drug design.
  • Investigation of the chemical profiles of selected medicinal herbs by extraction, analysis, identification and quantification of chemical constituents. Evaluation of medicinal effects attributed to herbs by examining published information about the pharmacological activity of the constituents, or by subjecting extracts or isolated constituents to relevant analytical, chemical and/or biological assays.
  • Discovery of Australian plants with medicinal potential.
