Clinical Trials

Numerous clinical trials evaluate Tranylcypromine across Phases 1 through 4 and unassigned protocol stages, featuring completed, terminated, and unknown recruitment statuses. Research spans psychiatric, cardiovascular, and hematologic disorders, including major depressive disorder, treatment-resistant depression, bipolar disorder, autonomic failure with orthostatic hypotension, acute myeloid leukemia, and myelodysplastic syndrome. Sponsored by academic, psychiatric, and government institutions—such as Duke University, Vanderbilt University, the Centre for Addiction and Mental Health, and the National Institute of Mental Health—these evaluations highlight the compound's application in both oncologic combinatory regimens and neuro-psychiatric target binding assessments.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Tranylcypromine binds to and inhibits monoamine oxidase as well as CYP2A6, blocking the enzymatic degradation of monoamine neurotransmitters and disrupting downstream catabolic pathways. The resulting elevation in synaptic levels of serotonin, norepinephrine, and dopamine enhances central neurosignaling, which underlines its therapeutic relevance in clinical trial conditions such as major depressive disorder, bipolar depression, and acute myeloid leukemia.

Appendix RUO and cGMP Quality Standards
