Morellic acid is primarily used in research settings for its potential biological activity. It has shown interest in pharmaceutical studies due to its structural properties that may influence enzyme inhibition and anti-inflammatory effects. Some preliminary studies suggest it could play a role in the development of agents targeting metabolic or infectious diseases, though its applications remain largely experimental. It is also investigated for its natural origin and biosynthetic pathways, contributing to the understanding of fungal metabolites and their ecological roles. Due to its complex structure, it serves as a model compound in synthetic organic chemistry for developing new transformation and cyclization methods.
