The molecule called STF-62247 is currently being
replicated into related molecules suited for human drug development. Auckland
University senior research fellow Dr Michael Hay said the new molecule would
destroy kidney cells by inducing them to "recycle".
Usually health cells can survive on less nutrients, but
cancer cells cannot. This principle is being used by the researchers to create
molecules that can be used in future cancer drugs.
Human trials for the
drug are expected to begin in four years' time.
