Aspterric acid is primarily studied for its biological activity, particularly its potent herbicidal properties. It acts by inhibiting the enzyme dihydroxy-acid dehydratase (DHAD), which is essential in the biosynthesis of branched-chain amino acids in plants. This mode of action makes it a candidate for the development of new herbicides that target weed growth selectively without affecting resistant crops. Due to its natural origin and specific mechanism, it serves as a lead compound in designing eco-friendly agrochemicals. Research also explores its stability and derivatization to improve its field performance and environmental safety.
