Definitions

  • the invention relates to modulators of Cystic Fibrosis Transmembrane Conductance Regulator (CFTR), pharmaceutical compositions containing the modulators, methods of treatment of cystic fibrosis and CFTR-mediated disorders using such modulators and pharmaceutical compositions, and processes for making such modulators.
  • CFTR Cystic Fibrosis Transmembrane Conductance Regulator
  • Cystic fibrosis is a recessive genetic disease that affects approximately 83,000 children and adults worldwide. Despite progress in the treatment of CF, there is no cure.
  • CFTR mutations in CFTR endogenously expressed in respiratory epithelia lead to reduced apical anion secretion causing an imbalance in ion and fluid transport. The resulting decrease in anion transport contributes to increased mucus accumulation in the lung and accompanying microbial infections that ultimately cause death in CF patients.
  • CF patients In addition to respiratory disease, CF patients typically suffer from gastrointestinal problems and pancreatic insufficiency that, if left untreated, result in death.
  • CFTR2 is a cAMP/ATP-mediated anion channel that is expressed in a variety of cell types, including absorptive and secretory epithelia cells, where it regulates anion flux across the membrane, as well as the activity of other ion channels and proteins.
  • CFTR In epithelial cells, normal functioning of CFTR is critical for the maintenance of electrolyte transport throughout the body, including respiratory and digestive tissue.
  • CFTR is composed of 1480 amino acids that encode a protein which is made up of a tandem repeat of transmembrane domains, each containing six transmembrane helices and a nucleotide binding domain. The two transmembrane domains are linked by a large, polar, regulatory (R)-domain with multiple phosphorylation sites that regulate channel activity and cellular trafficking.
  • R regulatory
  • Chloride transport takes place by the coordinated activity of ENaC (epithelial sodium channel) and CFTR present on the apical membrane and the Na + -K + -ATPase pump and Cl- channels expressed on the basolateral surface of the cell.
  • Secondary active transport of chloride from the luminal side leads to the accumulation of intracellular chloride, which can then passively leave the cell via Cl- channels, resulting in a vectorial transport.
  • Arrangement of Na + /2Cl-/K + co-transporter, Na + -K + -ATPase pump and the basolateral membrane K + channels on the basolateral surface and CFTR on the luminal side coordinate the secretion of chloride.
  • CFTR modulators have recently been identified. These modulators can be characterized as, for example, potentiators, correctors, potentiator enhancers/co-potentiators, amplifiers, readthrough agents, and nucleic acid therapies. CFTR modulators that increase the channel gating activity of mutant and wild-type CFTR at the epithelial cell surface are known as potentiators. Correctors improve faulty protein processing and resulting trafficking to the epithelial surface. Ghelani and Schneider- Futschik (2020) ACS Pharmacol. Transl. Sci.

For example, tritium ( 3 H)- and/or carbon-14 ( 14 C)- labelled compounds are particularly useful for various types of assays, such as substrate tissue distribution assays, due to relatively simple preparation and excellent detectability.
  • deuterium ( 2 H)-labelled ones are therapeutically useful with potential therapeutic advantages over the non- 2 H-labelled compounds.

  • deuterium is represented as “ 2 H” or “D.”
  • the deuterium ( 2 H)-labelled compounds and salts can modulate the oxidative metabolism of the compound by way of the primary kinetic isotope effect.
  • the primary kinetic isotope effect is a change of the rate for a chemical reaction that results from exchange of isotopic nuclei, which in turn is caused by the change in ground state energies necessary for covalent bond formation after this isotopic exchange.
  • Exchange of a heavier isotope usually results in a lowering of the ground state energy for a chemical bond and thus causes a reduction in the rate-limiting bond breakage. If the bond breakage occurs in or in the vicinity of a saddle-point region along the coordinate of a multi-product reaction, the product distribution ratios can be altered substantially.
