Banksialactone A is the simplest and major analogue of a family of isochromanones isolated from an Australian fungus, Aspergillus banksianus, by researchers at Macquarie University, Australia and Microbial Screening Technologies in 2018. While banksialactone A showed only weak activity in in-house chemotherapeutic bioassays, analogues containing the core structure were moderately active, demonstrating its potential as a chemical scaffold.
