Abstract:
Compounds having activity as phosphate transport inhibitors, more specifically, inhibitors of intestinal apical membrane Na/phosphate co-transport, are disclosed. The compounds have the following structure (I): including stereoisomers, pharmaceutically acceptable salts and prodrugs thereof, wherein X, Y and A are as defined herein. Methods associated with preparation and use of such compounds, as well as pharmaceutical compositions comprising such compounds, are also disclosed.
Abstract:
The present disclosure is directed to compounds and methods for the treatment of disorders associated with fluid retention or salt overload, such as heart failure (in particular, congestive heart failure), chronic kidney disease, end-stage renal disease, liver disease, and peroxisome proliferator-activated receptor (PPAR) gamma agonist-induced fluid retention. The present disclosure is also directed to compounds and methods for the treatment of hypertension. The present disclosure is also directed to compounds and methods for the treatment of gastrointestinal tract disorders, including the treatment or reduction of pain associated with gastrointestinal tract disorders.
Abstract:
The present disclosure is directed to a pharmaceutical composition comprising a compound of formula (X), in combination with another active agent, and to the use of said composition in methods for the treatment of disorders associated with fluid retention or salt overload or gastrointestinal tract disorders, such as irritable bowel syndrome and constipation associated with cystic fibrosis. The methods generally comprise administering to a mammal in need thereof a pharmaceutical composition comprising such a compound, that is designed to be substantially active in the gastrointestinal (GI) tract to inhibit NHE-mediated antiport of sodium ions and hydrogen ions therein. More particularly, the method comprises administering to a mammal in need thereof a pharmaceutical composition comprising such a compound, that inhibits NHE-3, -2 and/or -8 mediated antiport of sodium and/or hydrogen ions in the GI tract and is designed to be substantially impermeable to the layer of epithelial cells, or more specifically the epithelium of the GI tract. As a result of the compound being substantially impermeable, it is not absorbed and is thus essentially systemically non-bioavailable, so as to limit the exposure of other internal organs (e.g., liver, heart, brain, etc.) thereto.
Abstract:
Provided are non-NHE3-binding agents having activity as phosphate transport/uptake inhibitors in the gastrointestinal tract, including in the small intestine, methods for their use as therapeutic or prophylactic agents, and related methods of drug discovery.
