Regelidine is primarily used in research settings for its bioactive properties, particularly in the study of neurological pathways. It has shown potential as a modulator of ion channels, making it valuable in neuroscience for investigating cellular excitability and signal transmission. Due to its structural specificity, Regelidine serves as a lead compound in the development of neuropharmacological agents. It is also employed in studies related to pain perception and neurodegenerative conditions, where it helps elucidate the mechanisms underlying neuronal protection and dysfunction. Its application remains mostly confined to preclinical research, with ongoing studies exploring its therapeutic relevance.
