Embodiment 2
[0089] Embodiment 2, in vitro pharmacodynamics test 1——CPE inhibition experiment at the cardiomyocyte level
[0090] 1. Test materials:
[0091] 1. Test drug: the traditional Chinese medicine composition described in Example 1 of the present invention, the production batch number is: 030904;
[0092] 2. Experimental animals: SD suckling mice, which are second-class animals (certificate number SXK-11-00-0006), were purchased from the Institute of Zoology, Chinese Academy of Medical Sciences;
[0093] 3. Coxsackie virus CVB 3 : The strain number is Nancy strain, provided by the virus room of Wuhan Union Medical College Hospital.
[0094] 2. Test method:
[0095] (1) CVB 3 Virus virulence titration method (TCID 50 , 50% tissue culture infectious dose):
[0096] 1. Experimental steps:
[0097] Culture Vero cells in a 96-well plate; the virus was serially diluted 10-fold with serum-free medium, respectively 10 -1 ~10 -8 Dilution, then seeded in 96-well plate (the wells are...
Embodiment 3
[0132] Embodiment 3, in vitro pharmacodynamics test 2 - virus reproduction inhibition test
[0133] 1. Test materials:
[0134] Vero cells, Coxsackie virus CVB 3 And test drug: with embodiment 2.
[0135] 2. Test method:
[0136] 1. Inoculate Vero cells on a 24-well plate, and then add drugs and viruses in groups. The experimental design is shown in Table 13:
[0137] Table 13-well plates were inoculated with Vero cells and added drugs and viruses in groups
[0138]
[0139] 2. Harvest grouped cells according to different harvest time, and titrate CVB with virus titration method 3 virulence.
[0140] 3. Test results:
[0141] Harvest grouped cells according to different harvest time, and titrate CVB with virus titration method 3 Virulence, then TCID calculated by the Reed-Muench method 50 , the result is as image 3 shown.
[0142] In the development of antiviral drugs, if the drug can reduce the titer of the virus by more than 1 logarithmic value, it is considered...
