Questiomycin A is primarily explored for its potential in biomedical applications due to its antimicrobial properties. It has shown effectiveness against a range of bacterial strains, making it a candidate for the development of new antibiotics, particularly in the fight against drug-resistant bacteria. Additionally, research is being conducted to evaluate its anticancer properties, as preliminary studies suggest it may inhibit the growth of certain cancer cells. Its role in modulating biological pathways also makes it a subject of interest in biochemical research, aiming to uncover new therapeutic targets and mechanisms of action.
