experiment example 1

[0024] Experimental Example 1 Solid Medium Dilution Method Determination of FlabelliferinB Anti-Bacillus Calmette-Guerin (BCG) Absolute Concentration

[0025] Scrape the BCG culture from the inclined surface, add it to 3ml Middlebrook7H9 broth medium, add a small amount of glass beads, tighten the test tube cap, vibrate and grind vigorously on the vortex oscillator, and compare it with the standard McFarland turbidimetric tube (MacFarland No.1). Turbidity, that is to make 1mg / ml bacillus Calmette-Guerin (BCG) bacterial suspension. Flabelliferin B is made into a high-concentration stock solution with DMSO, and the stock solution is diluted to the required concentration with 5% Tween-80 sterile ultrapure water, and the diluted Flabelliferin B is added to 4ml Middlebrook7H11 agar medium according to the required dose (the culture Base has been sterilized by high-pressure steam at 121°C for 15 minutes, cooled to 50-55°C), mixed evenly, and made to contain Flabelliferin B, the conc...

Abstract

The invention discloses application of Flabelliferin B in preparing anti-tuberculosis drugs. The invention, in accordance with the current situation that the morbidity and mortality of tuberculosis are on the rise due to the high morbidity of the tuberculosis and the appearance multiple drug-resistant strains of the tuberculosis at present, discovers that the Flabelliferin B has an activity of significantly inhibiting tuberculosis, and the Flabelliferin B is good in application prospect. The invention discovers the application of the Flabelliferin B in preparing anti-tuberculosis drugs firstly; a completely new skeleton type is adopted and the activity on inhibiting the tuberculosis is extraordinarily strong, and the invention is impossible to be inspired by other compounds in any forms, therefore outstanding substantive features are achieved; and meanwhile, on the prevention and treatment of tuberculous infection, a significant progress is obviously made.

Description

technical field [0001] The present invention relates to a new application of the compound Flabelliferin B, in particular to the application of the Flabelliferin B in the preparation of anti-tuberculosis drugs. Background technique [0002] In recent years, the incidence of tuberculosis in the world has shown an increasing trend. According to the World Health Organization (WHO) estimates, the population infected by Mycobacterium tuberculosis (MTB) accounts for one-third of the world's population, and 5-10% of them are infected. become tuberculosis patients. There are 1.3 million cases of active tuberculosis patients in my country every year, including about 600,000 cases of infectious tuberculosis, and about 600,000 cases of infectious tuberculosis. It is one of the countries with a high burden of tuberculosis in the world. [0003] Since the advent of anti-tuberculosis drugs one after another, the treatment of tuberculosis has played an epoch-making change. However, due to...
