Embodiment 1

[0016] Embodiment 1: the preparation of compound Houttuynoid A tablet involved in the present invention:

[0017] Take 20 grams of compound Houttuynoid A, add 180 grams of conventional excipients for tablet preparation, mix well, and make 1000 tablets with a conventional tabletting machine.

Embodiment 2

[0018] Embodiment 2: the preparation of compound Houttuynoid A capsule involved in the present invention:

[0019] Get 20 grams of compound Houttuynoid A, add conventional auxiliary materials such as starch 180 grams for preparing capsules, mix well, and pack into capsules to make 1000 tablets.

[0020] The following pharmacodynamic experiments will further illustrate its drug activity.

experiment example 1

[0021] Experimental example 1 Determination of the absolute concentration of Houttuynoid A anti-BCG (BCG) by solid medium dilution method

[0022] Scrape the BCG culture from the slant, 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 prepare 1mg / ml bacillus Calmette-Guerin (BCG) bacterial suspension.

[0023] Make Houttuynoid A into a high-concentration stock solution with DMSO, dilute the stock solution to the required concentration with 5% Tween-80 sterile ultrapure water, and add the diluted Houttuynoid A to 4ml Middlebrook7H11 agar medium according to the required dose (The medium has been sterilized by high pressure steam at 121°C for 15 minutes, cooled to 50~55°C), mixed evenly to make Houttuynoid A, the concentrations are 6.0 ug / ml, 4.0 ug / ml, 3.0 ug / ml, 2.0...

Abstract

The invention discloses an application of Houttuynoid A in preparing medicines for inhibiting tubercle bacillus. The application of Houttuynoid A in preparing medicines for inhibiting tubercle bacillus aims at the current situation that high tuberculosis incidence and the appearance of multiple-resistant strains of tubercle bacillus result in the rising tendency in the incidence and mortality rate of tuberculosis, and Houttuynoid A is found to have remarkable tubercle bacillus inhibitory activity and good application prospect. The application of Houttuynoid A in preparing medicines for inhibiting tubercle bacillus is disclosed for the first time, has prominent substantive features and no any possibility for other compounds to give any inspiration, and simultaneously has remarkable progress when used for preventing and treating tubercle bacillus infection.

Description

technical field [0001] The invention relates to the application field of pharmaceutical compounds, in particular to the application of Houttuynoid A 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, of which 5-10% Infected people become TB 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 the irregular treatment ...
