Abstract
The invention discloses Houttuynoid C and prepare the application in anti-tubercle bacillus drugs.The present invention is directed to that current incidence of tuberculosis is high, the appearance of tubercule bacillus multiple antibiotic resistant strain, make incidence of tuberculosis and mortality rate present situation in rising trend, find that Houttuynoid C has the activity significantly suppressing tulase, there is good application prospect.The purposes of the Houttuynoid C that the present invention relates in preparation treatment anti-tubercle bacillus drugs belongs to first public, because framework types belongs to brand-new framework types, and it is unexpectedly strong for tulase inhibit activities, there is not the possibility being provided any enlightenment by other compounds, possess outstanding substantive distinguishing features, the control simultaneously for tubercle bacillus affection obviously has significant progress.
Description
Technical field
The present invention relates to medical compounds application, be specifically related to Houttuynoid C and preparing the application in anti-tubercle bacillus drugs.
Background technology
Global morbidity lungy is in increasing trend in recent years, estimate according to the World Health Organization (WHO), the current whole world is by mycobacterium tuberculosis (Mycobacterium tuberculosis, MTB) population infected accounts for 1/3rd of world population, and wherein the infected of 5 ~ 10% becomes tuberculosis patient.There is active tuberculosis patient 1,300,000 example in China, wherein infectiousness pulmonary tuberculosis about 600,000 example every year, wherein infectiousness pulmonary tuberculosis about 600,000 example, is one of global tuberculosis high burden country.
Come out one after another from antituberculotics, make treatment lungy play epoch-making change.But due to the Case management still not very specification of tuberculosis patient, irregular chemotherapy, abuse antituberculotics, makes drug resistance of tuberculosis situation day by day serious, and the change of drug resistance more trends towards multi-medicament drug resistance simultaneously, this causes extreme difficulties to preventing and controlling lungy.Therefore find new antituberculotics, the antituberculotics of especially anti-multidrug resistance is to protection people's health, significant.
Summary of the invention
The compound H outtuynoid C that the present invention relates to is one and delivers (Chen in 2012, S.D.et al., 2012.Houttuynoid C_E, Anti-Herpes Simplex Virus Active Flavonoids with Novel Skeletonsfrom Houttuynia cordata.Organic Letters14 (7), 1772 – 1775.) New skeleton compound, this compound has brand-new framework types, current purposes only relates to anti-herpes simplex virus activity (Chen, S.D.etal., 2012.Houttuynoid C_E, Anti-Herpes Simplex Virus Active Flavonoids with NovelSkeletons from Houttuynia cordata.Organic Letters14 (7), 1772 – 1775.), the purposes of the Houttuynoid C that the present invention relates in preparation treatment anti-tubercle bacillus drugs is belonged to first public, because framework types belongs to brand-new framework types, and it is unexpectedly strong for tulase inhibit activities, there is not the possibility being provided any enlightenment by other compounds, possesses outstanding substantive distinguishing features, control simultaneously for tubercle bacillus affection obviously has significant progress.
Summary of the invention
The object of the invention is to not find that it has the present situation of the report of anti-tubercular according in existing Houttuynoid C research, provide Houttuynoid C and preparing the application in anti-tubercle bacillus drugs.
Described compound H outtuynoid C-structure is as shown in formula I:
The object of the invention is achieved by the following technical programs:
Inventor first does examination bacterial strain with bacillus calmette-guerin vaccine, the anti-tubercle bacillus activity of disk diffusion method to Houttuynoid C is adopted to carry out preliminary test, according to the result of preliminary test, the present invention uses this compound of solid medium By Dilution to bacillus calmette-guerin vaccine again, the minimal inhibitory concentration of the H37Rv strain of mycobacterium tuberculosis type strain and substance of medicines-resistant branched tubercle bacillus (MDR MTB) three kinds of tulases, experimental result confirms that Houttuynoid C has very strong anti-tubercle bacillus and anti-drug resistance tulase is active, can be used as the lead compound for the treatment of tubercle bacillus affection disease, also can be used for preparation treatment tubercular drugs.
Compared with prior art, the present invention has following beneficial effect:
1. the invention provides a kind of Houttuynoid C that can be used for antituberculosis treatment, thus expand the kind of anti-tubercle bacillus drugs;
2. the appearance of, tubercule bacillus multiple antibiotic resistant strain high for current incidence of tuberculosis and HIV (human immunodeficiency virus) double infection, make incidence of tuberculosis and mortality rate present situation in rising trend, the present invention finds that Houttuynoid C has the feature of anti-tubercle bacillus and drug resistant M bacterium activity, can be used for the preparation of antituberculotics, there is boundless application prospect;
3. the purposes of the Houttuynoid C that the present invention relates in preparation treatment anti-tubercle bacillus drugs belongs to first public, because framework types belongs to brand-new framework types, and it is unexpectedly strong for tulase inhibit activities, there is not the possibility being provided any enlightenment by other compounds, possess outstanding substantive distinguishing features, the control simultaneously for tubercle bacillus affection obviously has significant progress.
