News Flash:
China News Service, May 5th. Lianhe Zaobao quoted AP news today that the US Army Biological Defense Laboratory recently found the first strong evidence that drugs can finally control the SARS virus. The laboratory is working day and night, perseveringly seeking a solution.
Scientists are focusing on existing antiviral drugs in pharmacies, hoping to find one that can quickly save patients with this new respiratory disease. Although most of these drugs have been ineffective so far, one has brought hope - natural anti-infection protein interferon.
At the same time, based on the understanding of the internal mechanism of the SARS virus, scientists are testing some experimental compounds that seem particularly fascinating. What may play a key role is a kind of protease inhibitors that can stop the SARS virus cold. Protease inhibitors are chemical analogs of drugs used to treat AIDS.
These accidental discoveries (according to scientists) are just the first step in the search for SARS treatment. All tests are carried out in test dishes. Even if the effect is significant in the laboratory, it may be disappointing when used on humans. In the next few months, they are expected to test 100,000 compounds, or even up to 500,000.
Interferon is a common antiviral agent in the human body. It can be replicated by genetic engineering, and there are various forms of interferon for commercial use. The US Army laboratory found that a type of interferon beta blocks the SARS virus in test dishes. However, if it is given to patients, the dosage needs to be 10 times higher. But experts say that the dosage in the human body may be smaller.
