Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 19/071,495, filed Mar. 5, 2025, which is a continuation of International Application No. PCT/US2023/073543, filed Sep. 6, 2023, which claims the benefit of and priority to U.S. Provisional Patent Application No. 63/404,440, filed Sep. 7, 2022, each of which are hereby incorporated by reference in their entireties for all purposes. BACKGROUND Cystic fibrosis (CF), an autosomal recessive disorder, is caused by functional deficiency of the cAMP-activated plasma membrane chloride channel, cystic fibrosis transmembrane conductance regulator (CFTR), which results in pulmonary and other complications. The gene encoding CFTR has been identified and sequenced (See Gregory, R. J. et al. (1990) Nature 347:382-386; Rich, D. P. et al. (1990) Nature 347:358-362), (Riordan, J. R. et al. (1989) Science 245:1066-1073). CFTR, a member of the ATP binding cassette (ABC) superfamily is composed of two six membrane-spanning domains (MSD1 and MSD2), two nucleotide bind domains (NBD1 and NBD2), a regulatory region (R) and four cytosolic loops (CL1-4). CFTR protein is located primarily in the apical membrane of epithelial cells where it functions to conduct anions, including chloride, bicarbonate, and thiocyanate into and out of the cell. CFTR may have a regulatory role over other electrolyte channels, including the epithelial sodium channel ENaC. In cystic fibrosis patients, the absence or dysfunction of CFTR leads to exocrine gland dysfunction and a multisystem disease, characterized by pancreatic insufficiency and malabsorption, as well as abnormal mucociliary clearance in the lung, mucostasis, chronic lung infection and inflammation, decreased lung function and ultimately respiratory failure. While more than 1,900 mutations have been identified in the CFTR gene, a detailed understanding of how each CFTR mutation may impact channel function is known for only a few. (Derichs, European Respiratory Review, 22:127, 58-65 (2013)). The most frequent CFTR mutation is the in-frame deletion of phenylalanine at residue 508 (ΔF508) in the first nucleotide binding domain (NBD1). Over 70% of cystic fibrosis patients have a deletion at residue 508 in at least one CFTR allele. The loss of this key phenylalanine renders NBD1 conformationally unstable at physiological temperature and compromises the integrity of the interdomain interface between NDB1 and CFTR's second transmembrane domain (ICL4). The ΔF508 mutation causes production of misfolded CFTR protein which, rather than traffic to the plasma membrane, is instead retained in the endoplasmic reticulum and targeted for degradation by the ubiquitin-proteasome system. The loss of a functional CFTR channel at the plasma membrane disrupts ionic homeostasis and airway surface hydration leading to reduced lung function. Reduced periciliary liquid volume and increased mucus viscosity impede mucociliary clearance resulting in chronic infection and inflammation. In the lung, the loss of CFTR-function leads to numerous physiological effects downstream of altered anion conductance that result in the dysfunction of additional organs such as the pancreas, intestine and gall bladder. By studying the mechanistic aspects of CFTR misfolding and corrections, small molecules have been identified as CF modulators, that can act as stabilizers. Despite the identification of compounds that modulate CFTR, there is no cure for this fatal disease and identification of new compounds and new methods of therapy are needed as well as new methods for treating or lessening the severity of cystic fibrosis and other CFTR mediated conditions and diseases in a patient.
