The compounds of formula (I) are hydrophilic aryl phosphate, thiophosphate, and aminophosphate intestinal apical membrane Na-mediated phosphate co-transportation inhibitors. The compounds can be administered orally, where they act to inhibit Na-dependent phosphate uptake in the intestines, or internally, where they interact with the phosphate control functions of the kidneys and parathyroid. They are useful for inhibiting sodium-mediated phosphate uptake, reducing serum PTH, calcium, calcitriol, and phosphate, and treating renal disease in an animal, including a human.
