PGD97

Description: PGD97 is a selective cyclic peptide inhibitor targeting the CAL/CFTR interaction, with its desulfurization-cyclized form exhibiting a KD value of 6 nM for the CAL PDZ domain. It shows a selectivity of at least 130-fold over the NHERF1/2 PDZ domains. PGD97 stabilizes F508del-CFTR on the cell membrane, enhancing CFTR function necessary for normal pulmonary fluid balance. This compound is applicable in cystic fibrosis research.
