Pendrin is induced by IL-4 or IL-13 in airway epithelial cells and is highly expressed in the lung tissues of asthma model mice or asthma patients. The signal transducer and activator of transcription (STAT) 6, the critical transcriptional factor for IL-4 or IL-13 signals, is required for IL-4– or IL-13–induced pendrin expression. Although the pathological roles of pendrin have been confirmed by the analyses of model mice, the underlying mechanisms are still unclear. Furthermore, pendrin has a potential to be correlated with other pulmonary diseases—chronic obstructive pulmonary disease, environmental chemical compound–exposed diseases or infectious diseases. In addition to these detrimental effects in pathological settings, the physiological role of pendrin in the lung, such as promoting antimicrobial activity, may be protective. Thus, whereas pendrin inhibition appears as a promising therapeutic strategy to treat asthma and other chronic respiratory diseases, it will be important to evaluate the effect of this inhibition in the lungs and other organs.

The identification of CFTR pharmacological modulators may be achieved by screening highly diverse synthetic or natural compound libraries using high-throughput methods. A convenient assay for CFTR function is based on the halide sensitivity of the yellow fluorescent protein (YFP). CFTR activity can be simply assessed by measuring the rate of YFP signal decrease caused by iodide influx. This assay can be automated to test thousands of compounds per day.

Mutations affecting the CFTR gene cause cystic fibrosis (CF), a multi-organ severe disease. The most common CF mutation, F508del, impairs the processing and activity (gating) of CFTR protein. Other mutations, like G551D, only cause a gating defect. Processing and gating defects can be targeted by small molecules called generically correctors and potentiators, respectively. Aminoarylthiazoles (AATs) represent an interesting class of compounds that includes molecules with dual activity, as correctors and potentiators. With the aim to improve the activity profile of AATs, we have now designed and synthesized a library of novel compounds in order to establish an initial SAR that may provide indications about the chemical groups that are beneficial or detrimental for rescue activity. The new compounds were tested as correctors and potentiators in CFBE41o-expressing F508del-CFTR using a functional assay. A dual active compound, AAT-4a, characterized by improved efficacy and marked synergy when combined with the corrector VX-809 has been identified. Moreover, by computational methods, a possible binding site for AATs in nucleotide binding domain NBD1 has been detected. These results will direct the synthesis of new analogues with possibly improved activity. Copyright © 2015 The Authors. Published by Elsevier Masson SAS.. All rights reserved.
