CFTRinh-172 (also known as CFTR Inhibitor172; CFTR-Inh 172; CFTR inhibitor 172) is a potent, voltage-independent, and selective inhibitor of CFTR (Cystic fibrosis transmembrane conductance regulator) with potential anti-fibrotic and anti-diarrhea effects. It inhibits CFTR with a Ki of 300 nM, and exhibits little/no effects on MDR1, ATP-sensitive K+ channels, or other transporters. CFTRinh-172 could reversibly inhibit CFTR short-circuit current in less than 2 minutes in a voltage-independent manner.
ln Vitro |
Inhibition by CFTR(inh)-172 is complete in around 10 minutes (t1/2=4 min) and is reversed after roughly 5 minutes at t1/2. CFTRinh-172 suppresses FRT after 24 hours at doses up to 100 μM[1] Cells are non-toxic. CFTR(inh)-172 does not modify the CFTR unitary conductance (8 pS) but reduces the open probability by >90% at Ki=0.6 μM. This effect is due to increasing the average channel off time without changing the average channel on time. The Ki value of wild-type, G551D, and G1349D CFTR for blocking Cl- current is approximately 0.5 μM; however, for vF508 CFTR, the Ki is drastically lowered to 0.2 μM [2].

ln Vivo |
In mice, cholera toxin-induced small intestinal fluid secretion was reduced by almost 90% after a single intraperitoneal injection of CFTR(inh)-172 (250 μg/kg) within 6 hours. In mouse models, CFTR(inh)-172 is not harmful at high concentrations. While inactive CFTRinh-172 analogues do not suppress fluid secretion, CFTRinh-172 dramatically decreases fluid secretion into the saline control circuit [1].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
