Cat.No. 2510 - Talniflumate | C21H13F3N2O4 | CAS No. 66898-62-2
Description: CaCC blocker and Cl-/HCO3- exchange inhibitor
Chemical Name: 2-[[3-(Trifluoromethyl)phenyl]amino]-1,3-dihydro-3-oxo-1-isobenzofuranyl 3-pyridinecarboxylic acid ester
Purity: ≥99% (HPLC)

Biological Activity

Calcium-activated chloride channel (CaCC) (hCLCA1/mCLCA3) blocker; reduces mucin synthesis and release in cell culture and animal models. Possesses anti-inflammatory actions via inhibition of cyclooxygenases and inhibits Cl-/HCO3- exchanger activity. Increases survival in a cystic fibrosis mouse model of distal intestinal obstructive syndrome.

Programmed Cell Death

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.

Pathways for Talniflumate


Apoptosis Signaling Pathway

Apoptosis is a physiological process for cell death that is critical during aging and development. It may also be referred to as cell 'suicide'. Apoptosis can be triggered by events both inside and outside of the cell.
