[Display omitted] Cystic fibrosis (CF) is an autosomal recessive disease resulting from mutations on both copies of the CFTR gene. Phenylalanine deletion at position 508 of the CFTR protein (F508del-CFTR) is the most frequent mutation in CF patients. Currently, the most effective treatments of CF use a dual or triple combination of CFTR correctors and potentiators. In triple therapy, two correctors (C1 and C2) and a potentiator are employed. Herein, we describe the identification and exploration of the SAR of a series of 4-aminopyrrolidine-2-carboxylic acid C2 correctors of CFTR to be used in conjunction with our existing C1 corrector series for the treatment of CF.
