2-(3-cyano group-4-substituted-phenyl)-4-methyl isophthalic acid, 3-selenazoles-5-formic acid and ester compound and preparation method
Technical field
The invention belongs to medical technical field, relate to 2-(3-cyano group-4-substituted-phenyl)-4-methyl isophthalic acid, 3-selenazoles-5-formic acid and ester compound and preparation method, be specifically related to 2-(3-cyano group-4-substituted-phenyl)-4-methyl isophthalic acid, 3-selenazoles-5-formic acid and ester compound thereof, pharmaceutically useful salt, pharmaceutically useful solvate and preparation method thereof, and the purposes of these compounds in medicine.
Background technology
Gout is a kind of global metabolic disease, and the height of its morbidity is subject to the impact of the many factors such as economic development level, environment, food habits, race, heredity, medical level, Case definition and statistical method, so various countries' report differs greatly.Show according to available data, European and American areas prevalence of hyperuricemia is about 2% ~ 18%, and the morbidity of gout is 0.2% ~ 1.7%.The indigenous Serum Uric Acid Level of the South Pacific is up to 64%.Japan, after World War II, along with the variation of dietary structure, takes in increasing of animal proteinum and fat, and hyperuricemia and patient with gout have and significantly increase trend, infer that prevalence of gout was is 0.5%.In a word, no matter be in American-European countries or in countries in Asia, the morbidity of gout has the trend increasing year by year, also ascendant trend linearly of the morbidity of China's hyperuricemia and gout.There is in recent years statistics to show, be about 0.84% in the total morbidity of all age bracket gouts.
Gout is that uric acid is accumulated in vivo owing to producing uric acid in body too much and the decline of kidney removing ability, causes urate crystal in joint and each internal organs precipitation.Clinical treatment gout medicine is mainly divided into promotion uric acid excretion and suppresses uricogenesis at present, and adopts adequate measure to improve relevant symptoms.Along with the raising of living standards of the people, be mainly that the proportion of various animal foods in dietary structure increases gradually, original rare prevalence of gout was and day Ju are increased.How to develop a kind of effectively, the medicine of safety and easy administration become to continue a problem solving.In decades, HPPIsopurind be clinically unique one for suppressing the medicine of uricogenesis, and be widely used in clinical as the gold medicine of gout, but need to repeat heavy dose of administration and maintain higher levels of drugs, cause the serious even fatal untoward reaction due to drug accumulation simultaneously.How to develop a kind of effectively, the medicine of safety and easy administration become to continue a problem solving.The disappearance of medicine, brings huge commercial opportunities to the exploitation of newtype drug.
Febuxostat (febuxostat) is first disclosed as in WO9209279A1, for xanthine oxidase inhibitor of new generation, be used for the treatment of clinically the too high disease of uric acid (gout), this medicine is that Japanese Teijin Ltd (Teijin) went on the market in Japanese publication 2004 beginning of the years, and go on the market its end of the year at U. S. application; IPSEN company is in Europe application listing, and European Union ratifies its listing in May, 2008.
