Dr Duggan’s research focuses on optimising the biological activity of low molecular weight compounds to produce new therapeutic leads and early intervention agents.
Current activities
Dr Duggan is Research Group Leader – Functional Small Molecules.
Part of his current research involves the design and synthesis of low molecular weight compounds that mimic the function of biologically active peptides.
Many peptides have been identified to have beneficial biological properties, however their application is limited because of their high water solubility and susceptibility to proteolytic degradation.
There is much interest in developing low molecular weight organic compounds that mimic the biological properties of peptides but are less water soluble and more resistent to degradation.
An example of this approach is the Conotoxin Mimics project in the Australian Biotech Growth Partnerships Theme, undertaken in partnership with:
Dr Duggan has recently begun a project in the Preventative Health Flagship aimed at producing small molecules that interupt fibril formation in Alzheimer’s disease.
-
Monash University, Melbourne, Victoria, Australia
-
the Australian Biotech company, Neurodisovery.
Conotoxins are found in the venom of marine cone snails.
Omega-conotoxin GVIA in particular has potent non-addictive analgesic properties.
A related peptide, Ziconotide or Prialt, has reached the clinic for the treatment of chronic neuropathic pain where morphine-based therapeutics are not effective.
However, the mode of delivery (intrathecal) and side effects associated with this peptide drug has encouraged researchers to try to find low molecular weight compounds with similar therapeutic effects but with better pharmokinetic properties.
Dr Duggan’s group has been preparing low molecular weight mimics of omega-conotoxin GVIA in partnership with Neurodiscovery and Monash University.
