Some 2-(diethylamino)-7-hydroxy-4H-1-benzopyran-4-one derivatives, potentially useful as activators of the cystic fibrosis transmembrane conductance regulator (CFTR), were prepared. The synthesized compounds were tested, together with others 2- (dialkylamino)-7-hydroxybenzopyran-4-one derivatives, by measuring their capacity to modify the kinetics of iodide influx in Fisher rat thyroid cells expressing wild type CFTR and the halide-sensitive yellow fluorescent protein. Among the tested compounds the dinitrile derivatives 8 and 9 are endowed with an activity comparable to the reference compound apigenin.

Abstract
Some 2-(diethylamino)-7-hydroxy-4H-1-benzopyran-4-one derivatives, potentially useful as activators of the cystic fibrosis transmembrane conductance regulator (CFTR), were prepared. The synthesized compounds were tested, together with others 2- (dialkylamino)-7-hydroxybenzopyran-4-one derivatives, by measuring their capacity to modify the kinetics of iodide influx in Fisher rat thyroid cells expressing wild type CFTR and the halide-sensitive yellow fluorescent protein. Among the tested compounds the dinitrile derivatives 8 and 9 are endowed with an activity comparable to the reference compound apigenin.
