Abstract
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.
Claims3
A method for treating a disease or disorder associated with a urea clearance insufficiency in a subject, said method comprising administering to the subject a composition comprising a pharmaceutically suitable excipient and a compound that inhibits transport of urea by the urea transporter across a cell membrane, wherein the compound is selected from N-benzyl-4-(4-chlorophenylsulfonyl)-2-(2-fluorophenyl)oxazol-5-amine;
- 5-(methylthio)-4-(phenylsulfonyl)-2-p-tolyl-1H-imidazole;
- 2-phenyl-4-tosyl-1H-imidazole-5-thiol;
- and S-2-phenyl-4-(phenylsulfonyl)-1H-imidazol-5-yl benzothioate.
