Biological Activity

Iloperidone is an atypical antipsychotic compound that acts as a potent antagonist of dopamine D2 and serotonin 5-HT2A receptors, while also targeting dopamine D3 and alpha1-adrenergic receptors. By blocking these neurotransmitter receptors, iloperidone modulates downstream G-protein-coupled receptor signaling pathways and neurotransmitter-mediated signaling cascades. Consequently, this multi-receptor antagonism alters intracellular second messenger dynamics and neural circuit excitability to suppress hyperdopaminergic phenotypes. [1]

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).
