CFTR corrector 4 (Compound 13), an active (R,R)-form enantiomer, is a highly potent and orally active cystic fibrosis transmembrane conductance regulator (CFTR) corrector. CFTR corrector 4 can increase CFTR levels at the cell surface and have the potential for treatment of cystic fibrosis[1].
CFTR corrector 4 possesses high potency and efficacy with a EC50 of 0.028 μM in this HBE-TECC assay that assess the CFTR function, this lead resides in undesirable drug-like space with high molecular weight, and high HPLC Log D, indicating high lipophilicity. HBE-TECC: (Human Bronchial Epithelial-Trans-Epithelial Current Clamp) assay[1].
CFTR corrector 4 is tested its potency and efficacy in human bronchial epithelial (HBE) cells with a EC50 value 130 nM in the cell surface expression (CSE-HRP) assay[1].
