摘要:
The invention provides compositions, pharmaceutical preparations and methods for inhibition of cystic fibrosis transmembrane conductance regulator protein (CFTR) that are useful for the study and treatment of CFTR-mediated diseases and conditions. The compositions and pharmaceutical preparations of the invention may comprise one or more hydrazide-containing compounds, and may additionally comprise one or more pharmaceutically acceptable carriers, excipients and/or adjuvants. The methods of the invention comprise, in certain embodiments, administering to a patient suffering from a CFTR-mediated disease or condition, an efficacious amount of a hydrazide-containing compound. In other embodiments the invention provides methods of inhibiting CFTR that comprise contacting cells in a subject with an effective amount of a hydrazide-containing compound. In addition, the invention features a non-human animal model of CFTR-mediated disease which model is produced by administration of a hydrazide-containing compound to a non-human animal in an amount sufficient to inhibit CFTR.
摘要:
Provided herein are bioactive agents comprising a compound that inhibits the ion transport activity of a cystic fibrosis transmembrane conductance regulator (CFTR) and that is linked to a macromolecule that interacts with a cell that expresses CFTR. The bioactive agents described herein are useful for treating diseases, disorders, and sequelae of diseases, disorders, and conditions that are associated with aberrantly increased CFTR activity, for example, secretory diarrhea.
摘要:
Provided herein are divalent hydrazide-polyethylene glycol conjugates that inhibit the ion transport activity of a cystic fibrosis transmembrane conductance regulator (CFTR). The conjugates described herein are useful for treating diseases, disorders, and sequelae of diseases, disorders, and conditions that are associated with aberrantly increased CFTR activity, for example, secretory diarrhea.
摘要:
Provided herein are highly water soluble, thiazolidinone derivative compounds and glycine hydrazide derivative compounds that inhibit the ion transport activity of the cystic fibrosis transmembrane conductance regulator (CFTR). The compounds, and compositions comprising the compounds, described herein are useful for treating diseases, disorders, and sequelae of diseases, disorders, and conditions that are associated with aberrantly increased CFTR activity, for example, secretory diarrhea. The compounds may also be used for inhibiting expansion or preventing formation of cysts in persons who have polycystic kidney disease.

摘要:
Provided herein are small molecule activators of calcium-activated chloride channels. These small molecules may be used for treatment of diseases and disorders that are treatable by activating calcium-activated chloride channels, such as cystic fibrosis, disorders related to salivary gland dysfunction (for example, Sjogren's syndrome and dysfunction following radiation injury), dry eye syndrome, and intestinal hypomotility.
摘要:
Provided herein are methods for identifying and characterizing agents that alter the volume of a cell. Methods are provided for rapid screening and identification of an agent that alters the capability of a small, neutrally charged solute transporter to transport the solute across a cell membrane. The methods described herein may be used to identify and characterize inhibitors of urea transporters, to identify and characterize inhibitors of aquaporins, and to identify and characterize inhibitors of other small, neutrally charged solutes such as glucose.
摘要:
Provided herein are pyrimido-pyrrolo-quinoxalinedione (PPQ) compounds, and compositions comprising these compounds, that inhibit cystic fibrosis transmembrane conductance regulator (CFTR) mediated ion transport and that are useful for treating diseases and disorders associated with aberrantly increased CFTR chloride channel activity. The compounds, and compositions comprising the compounds, described herein are useful for treating diseases, disorders, and sequelae of diseases, disorders, and conditions that are associated with aberrantly increased CFTR activity, for example, polycystic kidney disease. The compounds may be used for inhibiting expansion or preventing formation of cysts in persons who have polycystic kidney disease.
摘要:
Disclosed herein are methods of treating diseases including gastrointestinal disorders, such as secretory diarrheas, with the proanthocyanidin oligomer, crofelemer. Also disclosed is the anti-secretory effect of crofelemer on Calcium-activated chloride channels (CaCC) and Cystic fibrosis transmembrane conductance regulator (CFTR).
摘要:
Provided herein are methods for identifying compounds that are inhibitors of a calcium-activated chloride channel. Aminothiophene and aminothiazole compounds, and compositions comprising these compounds, described herein that inhibit efflux of chloride through a calcium-activated chloride channel are useful for treating diseases, disorders, and sequalae of diseases, disorders, and conditions that are associated with aberrantly increased chloride and fluid secretion, for example, secretory diarrhea.
