Research Summary: Marine Natural Products

Professor Molinski conducts research on the structural, synthetic and biological chemistry of marine natural products from marine sponges (Porifera), ascidians, and environmental bacteria. This includes chemical investigation and methods development for discovery of exceedingly small amounts of rare natural products ('nano-mole scale') using NMR, circular dichroism (CD) and mass spectrometry (MS), and synthesis of drug-like analogs for important therapeutic areas.

Therapeutic Areas:

  • Cancer chemo-therapeutics
  • Antifungal agents
  • Kinase and phosphatase inhibitors
  • Ca2+ channel modulators
  • Targeted-enzyme inhibitors for cancer and infectious disease

Academic Achievements

Education: Ph.D. (1985) Australian National University, Canberra; Postdoctoral studies (1985-87) Scripps Institution of Oceanography, UCSD; (1987-88) University of Utah.

Awards & Honors: Albert Hofmann Centennial Prize – elucidation of structures of natural marine products (2006); Chair of the Gordon Conference in Marine Natural Products (2004); Editorial advisory boards including Journal of Organic Chemistry, Journal of Natural Products, and Australian Journal of Chemistry.

Leadership Experience: Managed a high-visibility research effort for over 20 years. Consultant for biotech industries. Management and fund raising for national and international symposia on natural products sciences. One of the founding ‘Faculty of 1000’ reviewers in Biology.
