Definitions
- the present invention is a triaryl useful as a therapeutic or prophylactic agent for drugs, particularly hyperuricemia, gout, inflammatory bowel disease, diabetic nephropathy, diabetic retinopathy and the like, which are related to xanthine oxidase. It relates to a carboxylic acid derivative.
- the therapeutic agents for hyperuricemia can be broadly divided into uric acid excretion promoters and uric acid synthesis inhibitors, but uric acid excretion promoters have a diminished effect when renal function declines.
- the synthesis inhibitor alopurinol (Nippon Rinsho, 1996 Dec; 54 (12): 3364- 8 and Nippon Rinsho, 2003; 61, Suppl. 1: 197-20) is preferably used (hyperuricemia / gout Therapeutic guidelines for Japanese gout ⁇ Nuclear Nucleic Acid Metabolism Society, Guidelines 2002).
- Xanthine oxidase is an enzyme responsible for biosynthesis of uric acid.
- a xanthine oxidase inhibitor that inhibits xanthine oxidase is effective as a uric acid synthesis inhibitor in treating hyperuricemia and various diseases resulting therefrom.
- Aloprinol which is used clinically, is the only xanthine oxidase inhibitor currently in use.
- xanthine oxidase is known to have a role as an active oxygen producing enzyme (Drug Metab. Rev. 2004 May; 36 (2): 363-75).
- reactive oxygen induces inflammatory site force-in production (Free Radic. Biol. Med. 2001 May 15; 30 (10): 1055-66).
- autoimmune inflammatory diseases such as ulcerative colitis Crohn's disease (Scand. J. Gastroenterol. 2001 Dec; 36 (12): 1289-94), ischemia reperfusion injury (Biochem. Biophys. Res. Commun. 2004 Mar 5; 315 (2): 455-62 ) Is also known to be deeply related to active oxygen.
- VEGF vascular endothelial growth factor
- Xanthine oxidase inhibitors inhibit the production of active oxygen and are therefore effective in the treatment of these diseases.
- alopurinol is found in humans in ulcerative colitis (Aliment. Pharmacol. Ther. 2000 Sep; 14 (9): 1159-62) and vascular disorders associated with diabetes (Hypertension, 2000 Mar; 35 (3): 746 -5 1), it has been reported to be effective for chronic heart failure (Circulation, 2002 Jul 9; 106 (2): 221-6).
- aloxpurinol a xanthine oxidase inhibitor
- Aropurinoru has a nucleic acid-like structure, inhibiting pyrimidine metabolic pathway has been pointed out (Life Sci 2000 Apr 14; 66 (21):. 2051-70) o Therefore, safety Therefore, the development of a highly effective non-nucleic acid xanthine oxidase inhibitor with high medicinal properties is highly desired.
