Talniflumate BiologicalActivity
| Description | Talniflumate (BA 7602-06) is the prodrug of Niflumic acid (HY-B0493), exerting its activity in the body through conversion to niflumic acid by esterase[1]. Talniflumate is an orally active ca2+-activated Cl- channel (CaCC) blocker. Talniflumate can be used as an analgesic and anti-inflammatory agent in cystic fibrosis mouse model of distal intestinal obstructive syndrome[2]. |

| Target | IC50: ca2+-activated Cl- channel (CaCC)[1] |

| 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[1]. Animal Model: CF mice with distal intestinal obstructive syndrome (DIOS)[1] Dosage: 0.4 mg/g Administration: Oral chow; 21 days Result: Increased survival in a cystic fibrosis mouse model of distal intestinal obstructive syndrome. |
