Page/Page column 50, (2010/05/13)
The present invention relates to modulators of cystic fibrosis transmembrane conductance regulator ("CFTR"), compositions thereof, and methods therewith. The present invention also relates to methods of treating diseases using modulators of CFTR (Formula I) or pharmaceutically acceptable salts thereof, wherein: ring A is selected from: (a), (b), (c), (d), wherein: R1 is -CH3 -CF3 or -CN; R2 is hydrogen, -CH3, -CF3, -OH, or -CH2OH; R3 is hydrogen, -CH3, -OCH3, or -CN; provided that both R2 and R3 are not simultaneously hydrogen; and one of X and Y is nitrogen and the other is carbon.
