|Description||CFTRinh-172 (CFTR inhibitor 172) is a voltage-independent, selective CFTR inhibitor with Ki of 300 nM, showing no effects on MDR1, ATP-sensitive K+ channels, or a series of other transporters.|
CFTRinh-172 dose- and time-dependently inhibits CFTR-mediated I- transportation, and effectively inhibits CFTR activation by multiple types of agonists or activators.  CFTRinh-172, as a selective CFTR channel inhibitor, also completely abolishes the Cl− current in the rabbit acinar and duct cells of rabbit lacrimal gland.  CFTRinh-172 also induces ROS production, mitochondrial failure, and activation of the NF-κB signaling pathway, independently of CFTR inhibition. 
|In vivo||CFTRinh-172 (20 µg/6 h) completely abolishes the V. cholerae-induced intestinal fluid secretion without affecting V. cholerae growth in vivo. |
Screening procedures:Assays are done using a customized screening system consisting of a 3-meter robotic arm, CO2 incubator, plate washer, liquid-handling workstation, bar code reader, delidding station, and two FLUOstar fluorescence platereaders, each equipped with two syringe pumps and HQ500/20X (500 ± 10 nm) excitation and HQ535/30M (535 ± 15 nm) emission filters. The robotic system is integrated using SAMI version 3.3 software modified for two platereaders. Custom software is written in Microsoft VBA (Visual Basic for Applications) to compute base-line–subtracted, normalized fluorescence slopes (giving halide influx rates) from stored data files. The assay is set up by loading the incubator (37°C, 90% humidity, 5% CO2) with 40–60 96-well plates containing the FRT cells, and loading a carousel with 96-well plates containing test compounds and disposable plastic pipette tips. To initiate the assay, each well of a 96-well plate is washed three times in PBS (300 μl/wash), leaving 50 μL PBS. Ten microliters of a CFTR-activating cocktail (5 μM forskolin, 100 μM IBMX, 25 μM apigenin in PBS) is added, and after 5 minutes one test compound (0.5 μL of 1 mM DMSO solution) is added to each well to give 10 μM final concentration. After 10 minutes, 96-well plates are transferred to a platereader for fluorescence assay. Each well is assayed individually for CFTR-mediated I– transport by recording fluorescence continuously (200 ms per point) for 2 seconds (base line) and then for 12 seconds after rapid (<0.5 seconds) addition of 165 μL of isosmolar PBS in which 137 mM Cl– was replaced by I–.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
