General description

BL-1249 is a non-steroid anti-inflammatory drug and an inhibitor of the cyclooxygenase (COX) enzyme.

Application

BL-1249 has been used:
  • as an activator of mechano-gated K2P channel in contracted mouse ileum and colon tissues
  • as a TWIK related potassium channel (TREK2) modulator and in U-2 OS osteosarcoma cell line
  • as a TREK1 and TREK2 activator in mice.

Biochem/physiol Actions

BL-1249 also activates TWIK related potassium channel 2 (TREK2). It interacts with K2P channel at the negatively charged activator site and modulates channel opening.
BL-1249 is a putative activator of potassium TREK-1 channel.
