Description

Arylprop acyl-oxygen oxime acids urease inhibitor and synthetic and purposes
Technical field
The present invention relates to the method for making of a class arylprop acyl-oxygen oxime acids urease inhibitor and they are in the application of preparing in gastritis, Gastric Ulcer Treatment.
Background technology
Hp (Helicobacterpylari) can cause the various diseases such as gastritis, stomach ulcer, duodenal ulcer, gastratrophy, intestinal epithelial metaplasia, cancer of the stomach, gastric lymphoma.The World Health Organization in 1994 and IARC classify H.pylori as first kind carcinogen.According to statistics, the nearly half of world population has infected H.pylori, and in developing country, infection rate is up to 80-90%.The infection rate of China is 60% left and right.Gastritis sufferer's H.pylori recall rate is 80-90%, and Peptic Ulcers is higher, reaches more than 95%.The stomach ulcer that exceedes 90% duodenal ulcer and 80% left and right is due to H.pylori.Eradicating H.pylori is the above-mentioned disease for the treatment of and the prerequisite that prevents recurrence.What elimination H.pylori was the most frequently used at present is triplex process: a kind of proton pump inhibitor (omeprazole or lansoprazole) and two kinds of microbiotic (amoxycilline Trihydrate bp, Ofloxacine USP 23 or metronidazole).But omeprazole has obvious side effect: cause except meeting the side effects such as stomachache, vomiting, flatulence, also can cause liver weight increase etc.; Bring out in addition carcinoid of stomach, cause the danger such as renal failure.In addition H.pylori easily produces resistance to microbiotic used, and therefore, the efficient of this method declines just year by year.
As everyone knows, in stomach, be a strong acid environment, the main reason that Hp can be survived in stomach is its urease activity.The ammonia that urease hydrolyze urea discharges can improve pH value, and current research demonstration, and in receptor structure, urea molecule is Hp perception and the key factor of avoiding gastric acid environment.Therefore the H.pylori that act as of urease has built a suitable microenvironment.Some other germ, as proteus vulgaris (Proteus vulgaris), Proteus mirabilis (Proteus mirabilis), ureaplasma urealyticum (Ureaplasma urealyticum) etc., when they infect after urinary tract system, because the effect of urease causes the pH of urine and raises, cause the precipitation of the materials such as magnesium ammonium phosphate, and then develop into lithangiuria.There is the pathogenic bacteria of urease activity or to produce ammonia be self that vital movement provides nitrogenous source by urease hydrolyze urea, or the alkalescence of utilizing ammonia provides a suitable microenvironment for its existence.Therefore blocked urease activity, just can effectively kill this class germ.Therefore, urease inhibitor will become the first-line drug of this class disease for the treatment of.But existing urease inhibitor comes with some shortcomings, such as N-acetylhydroxylamine is because activity is low, consumption is large, caused some side effects, and highly active di(2-ethylhexyl)phosphate amides urease inhibitor is unstable in sour environment, has hindered its application clinically.Therefore the screening of new and effective low toxicity urease inhibitor is the key of this class medicine of exploitation.
Summary of the invention
Utilize computer modeling technique, based on scaffold hopping principle, designed and synthesized the new urea enzyme inhibitors with structure shown in I.Test shows, some compound has shown good inhibition activity to urease.
