Talniflumate

Talniflumate is a calcium-activated chloride channel (hCLCA1/mCLCA3) blocker that reduces mucin synthesis and releases in animal models and cell culture. It possesses anti-inflammatory actions via inhibition of Cox (cyclooxygenase) and inhibits Cl-/HCO3- exchange activity. It also increases survival in a cystic fibrosis mouse model of the distal intestinal obstructive syndrome. (In Vivo) :Talniflumate (oral chow; 0.4 mg/g; 21 days) significantly increases CF mouse survival from 26 to 77%. It does not alter crypt goblet cell numbers or change intestinal expression of mCLCA3 but tends to decrease crypt mucoid impaction.
