Prof Dame Margaret Anne Brimble
MSc (Auckland), PhD (Southampton, UK)
Dame Margaret Brimble FRS is a Distinguished Professor and Director of Medicinal Chemistry at the University of Auckland, New Zealand. She is an Associate Editor for Organic Letters, Deputy Director of the Maurice Wilkins Centre for Molecular Biodiscovery and Past-President of IUPAC Organic and Biomolecular Division III. She is a Fellow of the Royal Society London, Dame Companion of the New Zealand Order of Merit, has been inducted into the American Chemical Society Medicinal Chemistry Hall of Fame and received the Rutherford, Hector and MacDiarmid medals (Royal Society NZ), the Kiwinet BNZ Supreme award and Baldwins Research Entrepreneur 2019 commercialization awards and the Marsden medal (NZ Association of Scientists). She was awarded the Sosnovsky Award for Cancer Therapy and Natural Products award from the Royal Society of Chemistry. Her research focusses on the synthesis of novel bioactive natural products/antimicrobial peptides and the synthesis of lipopeptides for cancer vaccines and new biomaterials. She discovered the drug candidate trofinetide (NNZ2566) that was successful in phase 3 clinical trials for Rett Syndrome (Neuren Pharmaceuticals and Acadia Pharmaceuticals; FDA approval in 2022) and NNZ2591 (phase 2 clinical trials for Phelan-McDermid syndrome, Angelman syndrome, Pitt Hopkins syndrome and Prader-Willi syndrome). She is co-founder of the cancer immunotherapy company SapVax that has licensed her CLipPA peptide lipidation technology to develop self-adjuvanting peptide-based cancer vaccines. Her laboratory hosts NZ’s only laboratory accredited by Medsafe NZ to manufacture peptides under cGMP for human clinical trial.
Research | Current
Natural products have long been regarded as ‘nature’s medicine chest’ providing a rich source of lead compounds as invaluable platforms for developing front-line drugs. Our research focuses on making and modifying naturally occurring bioactive compounds that have been isolated from plants, animal tissue, microbes or marine and soil organisms, which are rare or hard to isolate in abundance. These compounds provide rich and diverse chemical structures that challenge the synthetic chemist to develop new flexible synthetic methodology for their construction. The preparation of synthetic analogues of the natural compound may improve the biological activity and provide an understanding of the mechanism of action of the naturally occurring compound.
Our research group also comprises a national peptide, peptidomimetic and glycopeptide chemistry facility that occupies a world-class laboratory in the Institute for Innovation in Biotechnology. The peptide synthesis laboratory supports growth in the burgeoning area of peptide therapeutics that is growing at twice the rate of small molecule therapeutics by engaging with the local biotech community to develop viable drug candidates based on peptide leads. An example is the development of NNZ2566 (named trofinetide by the WHO) for Neuren Pharmaceuticals that was successful in phase 3 clinical trials for Rett Syndrome (FDA approval pending in 2022). Our group has also discovered a second drug candidate NNZ2591 for Neuren entering phase 2 clinical trials for Phelan-McDermid, Angelman, Pitt Hopkins and Prader-Willi Syndromes, four debilitating neurodegenerative disorders with no approved treatments. Trofinetide and NNZ2591 have been granted fast track and orphan drug status by the FDA.
Profesor Brimble is also co-Founder of the cancer immunotherapy SapVax.llc that has licensed her CLipPA peptide lipidation technology to develop self-adjuvanting peptide-based cancer vaccines. Our laboratory has also been licensed by medsafe NZ for the GMP manufacture of peptides for the clinical trial of melanoma vaccines (MELVAC trial).
The synthesis of natural product peptides containing unnatural amino acids, depsipeptides, cyclic peptides and natural proteins that exhibit potent antimicrobial activity, is one theme in our peptide chemistry laboratory. Analogues of the natural peptides are then synthesised to either simplify or stabilise the molecule with the aim of producing a more potent analogue. The ability to combine contemporary organic reactions such as cross-metathesis, “peptide stapling”, click chemistry, thiol-ene chemistry and the preparation of unnatural amino-acid building blocks with modern solid phase synthesis methods provides a powerful peptidomimetic platform to combat the problem of increasing resistance to existing antibiotics. The peptide chemistry group also synthesizes peptide-based hydrogels with applications in bionanotechnology and regenerative medicine.
Our group also contributes to collaborative agrochemistry programmes focused on development of methanogen inhibitors, nitrification inhibitors, rat selective toxicants and new generation sanitizers.
