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.
化合物的化学式(I)为亲水性芳基磷酸酯、硫代磷酸酯和氨基磷酸酯,是肠道顶端膜Na介导的磷酸盐共同运输抑制剂。这些化合物可以经口服给药,在肠道中起到抑制Na依赖性磷酸盐摄取的作用,或者内部给药,在肾脏和甲状旁腺的磷酸盐控制功能中发挥作用。它们可用于抑制钠介导的磷酸盐摄取,降低血清PTH、钙、钙三醇和磷酸盐,治疗动物(包括人类)的肾脏疾病。
