Clinical Trials

Several clinical trials evaluate harmine hydrochloride, focusing on early-stage human research across Early Phase 1 and Phase 1 studies. Predominantly completed and sponsored by academic and clinical institutions such as the Psychiatric University Hospital Zurich and the Medical University of Vienna, these trials evaluate major depression, diabetes mellitus, ayahuasca constituents, and emotional and cognitive functions in healthy participants. Together, these investigations target both metabolic indications and central nervous system pathways, illustrating the broad therapeutic exploration of this alkaloid.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Harmine acts as a cell-permeant, competitive inhibitor of ATP binding to dual-specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A) and monoamine oxidases, thereby blocking downstream substrate phosphorylation and monoamine oxidation. This inhibition modulates central neurotransmission and cellular metabolic pathways, underlying its clinical evaluation in major depression, cognitive function, and diabetes mellitus.
