Griffith University has been awarded nearly $1.4 million in National Health and Medical Research Council funding to develop new classes of antibiotics, further work around mosquito-borne viruses and improve outcomes for people with acute mental illness.
Researchers also obtained success as part of a team led by other institutions, from Griffith Criminology Institute, Menzies Health Institute Queensland and Indigenous Research Unit.
The Institute for Glycomics received two of the grants, totalling $1.13 million in funding.
Research leader Professor Yaoqi Zhou and Dr Kate Seib, Dr Thomas Haselhorst, Associate Professor Helen Blanchard and Dr Yuedong Yang were awarded $607,967 for the project Developing species-specific, structure-targeting peptides as a novel class of antibiotics.
New classes of antibiotics
Professor Zhou said project was about developing new classes of antibiotics that are based on naturally occurring peptides.
“These peptides will be computationally designed to disrupt the structure of specific proteins essential for bacterial survival,” he said.
“This is different from typical antibiotics that inhibit functions of essential proteins by binding onto protein surfaces.
“Because protein surfaces are subject to spontaneous and induced mutations without significant changes to protein functions, those mutations with weaker binding to antibiotics will be evolutionary selected and cumulated and ultimately lead to drug resistance. Structure-disrupting inhibitors on the other hand destroy the foundation of protein function.
“Large-scale changes in structure will be much more difficult for pathogens to employ mutations to restore function. As a result, it is more difficult, if not impossible, for pathogens to develop resistance to this class of antibiotics. If successful, this approach can be used to develop resistance-free anti-viral and anti-cancer therapeutics.”
Vaccine development
Dr Adam Taylor was awarded $520,520 for the project The role of capsid protein nucleolar localisation in chikungunya virus: implications for vaccine development.
Institute director Professor Mark von Itzstein congratulated the winners for their success.
