| Abstract: | The synthesis of a small collection of sulfamoyl-4-oxoquinoline-3-carboxamides is described for use as correctors of defective gating of the DeltaF508-cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel. Several compounds with submicromolar potency were obtained. N-Ethyl 6-(ethylphenylsulfamoyl)-4-oxo-1,4-dihydroquinoline-3-carboxamide (7b) was found to be the most effective sulfonamide corrector of defective DeltaF508-CFTR gating. |
