Biological Activity

Lumiracoxib is a potent and highly selective cyclooxygenase-2 (COX-2) inhibitor with marked selectivity over COX-1. By targeting COX-2, it suppresses the conversion of arachidonic acid to pro-inflammatory prostaglandins, specifically reducing prostaglandin E2 (PGE2) synthesis. This inhibition blocks downstream inflammatory signaling pathways, resulting in attenuated inflammatory responses and reduced pain signaling in cellular and tissue models.

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).
