Ordering Information

Biological Activity

Moclobemide (Ro 111163) is a potent, reversible inhibitor of monoamine oxidase A (MAO-A). By selectively targeting MAO-A, it prevents the oxidative deamination of monoamine neurotransmitters, leading to increased extracellular concentrations of serotonin (5-HT), norepinephrine, and dopamine in brain tissue. This inhibition modulates central nervous system monoaminergic neurotransmission and downstream neuronal signaling, resulting in enhanced neurochemical signaling and neuroprotective phenotypes.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
