WHAT IS MPAP?

Detailed overview

MPAP (methylenedioxyphenylpropylaminopentane, 1-(3,4-methylenedioxyphenyl)-2-propylaminopentane) is a monoamine activity enhancer (MAE) from the propylaminopentane series developed by Jozsef Knoll, in which a benzodioxole ring replaces the phenyl ring of PPAP and the benzofuran ring of BPAP. MAEs do not release neurotransmitters; instead they increase the amount released per nerve impulse, so they strengthen signaling only when the neuron is already active. Like BPAP, MPAP enhances serotonin, norepinephrine and dopamine with roughly equal potency, in contrast to PPAP and selegiline, which act exclusively as catecholaminergic activity enhancers (CAEs). There is no MPAP-specific human or clinical data; the compound exists only as an unregulated experimental research chemical.

  • TAAR1 (intracellular trace amine receptor)Moderate
  • Dopamine / norepinephrine toneWeak

Safety

Side effects, stop signs, contraindications

Side effects · 6

  • No MPAP-specific human safety data: the profile is inferred almost entirely from related compounds (BPAP, PPAP) and anecdote
  • Possible mild stimulation, restlessness or sleep disturbance due to enhanced catecholaminergic activity
  • Mood shifts, irritability or anxiety possible, since it also enhances serotonin activity (broader monoaminergic effect than PPAP)
  • Narrow, bell-shaped (inverted-U) dose-response: more is not better and too high a dose may abolish the effect
  • Given the hepatotoxicity signal documented for BPAP, theoretical liver strain cannot be excluded by analogy
  • Unknown long-term safety profile, consequences of chronic use are not studied

Contraindications · 5

  • Avoid during pregnancy and breastfeeding, no safety data available
  • Avoid combining with other monoaminergic agents (antidepressants, MAO inhibitors, stimulants) due to risk of serotonergic or catecholaminergic excess
  • Caution advised with cardiovascular disease or hypertension due to the noradrenergic effect
  • Caution warranted with liver disease or elevated liver enzymes given the related compound's hepatotoxicity signal
  • Unapproved, experimental-only compound, human dosing and safety standards are not established
