Coulteropine is primarily used in research settings for its biological activity, particularly in studies related to enzyme inhibition and cellular signaling pathways. It has shown potential in modulating specific ion channels, making it valuable in neuropharmacological research. Due to its structural properties, it serves as a lead compound in the development of new agents targeting neurological disorders. Additionally, coulteropine has been investigated for its antimicrobial and anti-inflammatory effects, supporting its use in early-stage drug discovery. Its application in plant physiology studies also exists, where it helps in understanding alkaloid function in defense mechanisms.
