Used in research settings as a fluorescent probe due to its natural fluorescence, enabling visualization in cellular and molecular studies. Acts as a monoamine oxidase inhibitor, making it relevant in neuroscience for studying neurotransmitter regulation, including serotonin and dopamine metabolism, and diseases such as depression and Parkinson's. Investigated for its psychoactive properties and presence in psychoactive plant extracts, contributing to ethnopharmacological studies. Also serves as a precursor or intermediate in the synthesis of more complex alkaloids and pharmaceutical agents. Shows antimicrobial and antiparasitic activity in preliminary studies, suggesting potential for drug development. Additionally, used as a reference standard in laboratory analysis, particularly for detecting beta-carboline structures in biological samples.
