Abstract
This invention relates to a compound for treating or preventing bacteria infection, especially Helicobacter pylori infection, and accompanied diseases, and its preparation method and medical applications.
Description
Technical field
The present invention relates to prevention or treatment and infect the disease cause or to follow or compound, its preparation method and the medical usage of symptom by some bacterium (especially helicobacter pylori).
Background technology
(Helicobacterpylori is a kind of grow in stomach mucous membrane layer, microanaerobic gram negative bacterium H.pylori) to helicobacter pylori, it is reported that the whole world has half population can infect this pathogenic bacteria in life approximately.Nineteen eighty-three Marshall separates from gastritis sufferer's stomach mucous membrane sample first with Warren and obtains helicobacter pylori, this important discovery changed people to peptic ulcer disease because of understanding, therefore greatly promoted the development of gastroenterology research, two people also obtain Nobel's physiology in 2005 or medical science prize.Now clear and definite, helicobacter pylori is not only the arch-criminal who produces peptide ulceration, but also be gastritis and cancer of the stomach main diseases because of.Therefore, the World Health Organization is classified as I class carcinogens with it.
Helicobacter pylori spread path and bad life habits and diet residential areas are closely related, propagate very easily mutually in the daily life and infect.Though the infection rate developed country helicobacter pyloris such as the U.S. and West Europe has begun to descend, to developing countries' (comprising China), this numeral still gains momentum.Helicobacter pylori infection not only can cause a series of disease of upper digestive tract such as comprising chronic gastritis, peptide ulceration, non-ucler dyspepsia, adenocarcinoma of stomach, stomach non_hodgkin lymphoma and mucosa associated lymphoid tissue lymphoma, but also be associated with cardiovascular and cerebrovascular diseases, autoimmune disorder and some dermopathic morbidity or progress, thereby human beings'health and life in serious harm.
The poor effect of single antibiotic therapy helicobacter pylori infection, and make bacterium produce resistance easily.The treatment plan that medical circle is recommended is to unite to use proton pump inhibitor or ranitidine bismuth citrate to add two or three microbiotic i.e. so-called " triple therapy " or " quadruple chemotherapy ".Anti helicobacter pylori medicine thing commonly used at present comprises metronidazole, clarithromycin, amoxycilline Trihydrate bp, tsiklomitsin and Nifurazolidone etc.Because antibiotic long-term unreasonable use, helicobacter pylori is on the increase the resistance phenomenon of said medicine (special metronidazole and clarithromycin), has a strong impact on clinical result of treatment.
The difficulty that is faced on infection population that the whole world is huge and the clinical treatment calls anti-helicobacter pylori to infect the generation of new drug.This class drug candidate with good DEVELOPMENT PROSPECT should embody following characteristics: (1) structure is brand-new, and mechanism of action is different from existing medicine: (2) anti-microbial activity is strong, meets acid and stablizes; (3) narrow antimicrobial spectrum, the selectivity height, still effective to drug-fast helicobacter pylori; (4) use the difficult resistance phenomenon that takes place repeatedly.
Aminopeptidase is that a class can the catalytic pyrolysis polypeptide and the proteolytic enzyme of protein N terminal amino-acid residue, extensively be present in protokaryon and the eukaryotic cell, in the protein course of processing, be responsible for the initial amino acid of excision new polypeptide chain N end, protein maturation, transhipment in cell and location and function are regulated very important, by the cell physiological function of bringing into normal play essential.Therefore, aminopeptidase is a drug target that has much potentiality.The currently reported inhibitor of some aminopeptidases that shows has the activity that suppresses bacterium or parasite growth.(Leucyl aminopeptidase is a modulability biological enzyme rare in the aminopeptidase family LAP) to the leucine aminopeptidase(LAP) that the clone obtains from helicobacter pylori, infers that it is most important to the normal activities of keeping helicobacter pylori.
The present invention is a starting point with recombinant expressed helicobacter pylori leucine aminopeptidase(LAP), sets up based on the dynamic (dynamical) high flux screening model of relevant enzyme, has found that by extensive random screening a class specific effect is in the inhibitor of this enzyme.Experiment shows that this compounds has certain anti-microbial activity to helicobacter pylori.The invention provides the correlation technique and the application thereof of a synthetic class novel anti helicobacter pylori medicine.
Summary of the invention
The purpose of this invention is to provide pharmaceutically acceptable salt of a kind of formula I compound that can suppress infectation of bacteria (especially helicobacter pylori) or its;
Another object of the present invention has provided a kind of method of preparation I compound;
Another object of the present invention has provided a kind of pharmaceutical composition that contains formula I compound;
Another object of the present invention has provided the purposes that formula I compound is used to prepare disease medicaments such as prevention or treatment peptide ulceration.

The activity of embodiment 2 novel antibacterial series compounds
The leucine aminopeptidase(LAP) of helicobacter pylori is an allosteric enzyme, and hydrolysis specifically has the peptide bond of amino-acid residues such as Leu-, and its activity is regulated and control by divalent cation.Under the reaction conditions of 37oC, 50mM Tris-HCl (pH8.0) damping fluid and 0.5mM MnCl2, but leucine aminopeptidase(LAP) catalytic hydrolysis substrate L-leu-p-nitroanilide, and the product pNA (p-Nitroaniline) of generation has characteristic light to absorb at the 405nm place.By Spectra MAX340Microplate Reader absorbancy is detected, and converse relative inhibition [the Lei Dong of testing sample to leucine aminopeptidase(LAP), Ni Cheng, Ming-Wei Wang, Junfeng Zhang, Chang Shu and De-Xu Zhu.The leucyl aminopeptidase from Helicobacter pylori isan allosteric enzyme.Microbiology, 2005,151:2017-2023].In view of the above, by 32000 samples being carried out bioactivity screening and multiple sieve checking, finds a series of leucine aminopeptidase(LAP) to be had the active compound of inhibition, its half-inhibition concentration (IC50) is between 2-9 μ M.
In order to study the influence of above-claimed cpd, adopt agar dilution to measure their minimal inhibitory concentrations (MIC) to helicobacter pylori reference culture ATCC43504 to the helicobacter pylori life cycle.The result shows that compound N C00072450 has certain anti-helicobactor pylori activity, and its MIC value is 32 μ g/ml (seeing the following form).
Table 1. related compound of the present invention gathers (the positive contrast of Bestatin) to the restraining effect of leucine aminopeptidase(LAP) and helicobacter pylori reference culture ATCC43504
Above-mentioned example is as an illustration purpose only, and scope of the present invention is not so limited.It is conspicuous making amendment concerning the technician of field of medicine and chemical technology, and the present invention only is subjected to the restriction of claims scope.
