Definitions

  • the present invention relates to a compound or a pharmacologically acceptable salt thereof useful for the prevention or treatment of hyperphosphatemia or a disease associated with hyperphosphatemia.
  • Phosphorus is present in various forms in the body as an important component of the body such as DNA, RNA, or bone, and plays an important role in life support activities.
  • Phosphoric acid is mainly absorbed from food in the form of inorganic phosphorus in the digestive tract and excreted in the form of urine from the kidney (Non-patent Document 1). Blood phosphorus levels are maintained at a constant level through the action of vitamin D, parathyroid hormone (PTH), etc., and absorption in the digestive tract, renal excretion, and bone absorption and metabolism are controlled.
  • PTH parathyroid hormone
  • Non-patent Document 2 Excess phosphate binds to blood calcium and causes ectopic calcification in the cardiovascular system, which is regarded as a risk factor for cardiovascular diseases such as myocardial infarction (Non-patent Document 2).
  • Hyperphosphatemia secondarily causes hypocalcemia and, as a compensation, develops hyperparathyroidism characterized by elevated blood PTH levels, which is a sign of renal osteodystrophy. It is also a major factor.
  • hyperphosphatemia in patients with chronic renal failure decreases the QOL of chronic renal failure patients such as fractures and bone pain, and is a major factor in the death of chronic renal failure patients.
  • Non-patent Document 3 Calcium preparations have been shown to promote vascular calcification due to hypercalcemia (Non-patent Document 3), and polymer preparations have problems with compliance with medication taken by several g a day and digestive symptoms such as constipation and diarrhea (Non-Patent Document 4).
  • Non-Patent Document 5 metal salt preparations accumulate in the body (Non-Patent Document 5), and there are currently no sufficient therapeutic agents for treating hyperphosphatemia. It is said that sodium-dependent phosphate transporter expressed in small intestinal epithelial cells plays an important role in the absorption of inorganic phosphate in the digestive tract (Non-patent Document 6). Compounds that effectively inhibit the absorption of phosphorus from the gastrointestinal tract more efficiently than oral adsorbents, and improve the compliance with medications, digestive symptoms, and accumulation problems that were problematic in oral adsorbents It is expected to be possible. In view of the circumstances as described above, it is desired to develop a drug for preventing or treating new hyperphosphatemia or diseases associated with hyperphosphatemia. As compounds related to the present invention, there are compounds described in WO02011 / 136269, but the essential partial structure is different from the compounds of the present invention.
