Technical Data

Formula

C18H10F3NO3S2
Molecular Weight 409.4 CAS No. 307510-92-5
Solubility (25°C)* In vitro DMSO 82 mg/mL (200.29 mM)
Water Insoluble
Ethanol Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
9.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 180 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

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.
Targets
CFTR [1]
(in human airway cells)
300 nM(Ki)
In vitro CFTRinh-172 dose- and time-dependently inhibits CFTR-mediated I- transportation, and effectively inhibits CFTR activation by multiple types of agonists or activators. [1] 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. [2] CFTRinh-172 also induces ROS production, mitochondrial failure, and activation of the NF-κB signaling pathway, independently of CFTR inhibition. [3]
In vivo CFTRinh-172 (20 µg/6 h) completely abolishes the V. cholerae-induced intestinal fluid secretion without affecting V. cholerae growth in vivo. [4]

Protocol (from reference)

Kinase Assay:

[1]
  • 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–.
