Description

Diaryl propionyl-N-methyl hydroxamic acid type urease inhibitor and synthesis thereof and purposes
Technical field
The present invention relates to the method for making of a class Diaryl propionyl-N-methyl hydroxamic acid type urease inhibitor and they are preparing the application in gastritis, Gastric Ulcer Treatment.
Technical background
Hp (Helicobacter pylari) can cause the various diseases such as gastritis, stomach ulcer, duodenal ulcer, gastratrophy, intestinal epithelial metaplasia, cancer of the stomach, gastric lymphoma.H.pylori is classified as first kind carcinogen by the World Health Organization in 1994 and IARC.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 about 60%.The H.pylori recall rate of gastritis sufferer is 80-90%, and Peptic Ulcers is higher, reaches more than 95%.Duodenal ulcer more than 90% and the stomach ulcer of about 80% are caused by H.pylori.Eradicating H.pylori is the above-mentioned disease for the treatment of and the prerequisite preventing recurrence.What current elimination H.pylori was the most frequently used 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: except causing the side effects such as stomachache, vomiting, flatulence, liver weight increase etc. also can be caused; Bring out carcinoid of stomach in addition, 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, be a strong acid environment in stomach, 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 display, in receptor structure, urea molecule is Hp perception and the key factor 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., after they infect urinary tract system, because the effect of urease causes the pH of urine to raise, 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 utilize the alkalescence of ammonia to provide a suitable microenvironment for its existence.Therefore blocked urease activity, just can effectively kill this kind of germ.Therefore, urease inhibitor will become the first-line drug for the treatment of this kind of disease.But existing urease inhibitor comes with some shortcomings, such as N-acetylhydroxylamine due to activity low, consumption is large, result in some side effects, and highly active di(2-ethylhexyl)phosphate amides urease inhibitor is unstable in sour environment, hinders its application clinically.Therefore the screening of new and effective low toxicity urease inhibitor is the key developing this kind of medicine.
Utilize computer modeling technique, transformed by skeleton and move more, having designed and synthesized the new urea enzyme inhibitors with structure shown in I.Test shows, some compound shows excellent inhibit activities to urease.
Summary of the invention
The object of the invention is to design and synthesize a series of Diaryl propionyl-N-methyl hydroxamic acid (I) type urease inhibitor, on the basis of further investigation structure activity relationship, find the new urea enzyme inhibitors that activity is higher, toxic side effect is lower, and the method for making of Diaryl propionyl-N-methyl hydroxamic acid compound is provided.
