The new crown pneumonia COVID-19 continues to claim lives all over the world and infect millions of people. Although several vaccines have been available and their preventive effects have been proven, do those infected patients have better medicines? The good news is that scientists have found a good way to find specific drugs for the new crown, and based on this method, they have found two more effective drugs.
Medical news (Medical x Press) reported that COVID-19 is quite difficult. It mutates too quickly and too much, which makes the vaccine not 100% effective. It also shows that we now need more effective vaccines than ever before. Antiviral therapy, if vaccines are the "shield" against new coronary pneumonia, then antiviral drugs are the "long spear" against new coronary pneumonia.
In view of this demand, multinational research teams in Japan, the United States, and the United Kingdom have launched a plan to "effectively develop antiviral therapy". The researchers first established an experimental system to screen which drugs can help prevent infections. . The system uses a cell line called "VeroE6/TMPRSS2", which was developed by Dr. Takeda of the National Institute of Infectious Diseases in Japan last year. It is a modified version designed to test the new coronavirus (SARS-CoV). -2) A good carrier. Simply put, it is a "bait" that the new coronavirus can attack.
In order to determine whether the drug is helpful to fight the new coronavirus infection, we only need to mix VeroE6/TMPRSS2 with the test drug, and then put the new coronavirus in, if the drug is effective, then VeroE6/TMPRSS2 will remain the same, if not, VeroE6/TMPRSS2 Will be destroyed.
