Ordering Information

Biological Activity

Entacapone (OR-611) is a potent inhibitor of catechol-O-methyltransferase (COMT) and fat mass and obesity-associated protein (FTO) demethylation. By blocking COMT activity, it prevents the peripheral breakdown of levodopa, enhancing dopamine availability in central signaling pathways. Additionally, inhibition of FTO demethylase activity regulates metabolic homeostasis, impacting gluconeogenesis and energy expenditure. Entacapone is widely utilized in research addressing Parkinson's disease and metabolic disorders. [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).
