Since the emergence of the epidemic, scientists have been committed to studying various virus solutions. For ordinary people, one of the most expectations is specific drugs. Recently, some media reported that the new crown treatment drug recently discovered by Chinese scientists has been authorized by the national invention patent. This drug is stephanine, which is known to inhibit the replication of coronavirus by 15393 times.
However, after carefully reviewing the original patent and communicating with the inventor and industry experts, the interface pointed out in the report that equating the above patent authorization with the fact that stephanine has become a new crown treatment drug lacks scientific basis. In fact, just as a "promising candidate drug", it is said that stephanine is expected to be used in the treatment of new crown**
It is understood that the patent name of the invention is "pangolin coronavirus xcov and its application and the application of drugs against coronavirus infection". Note that the pangolin coronavirus xcov here is not a currently popular novel coronavirus, but the S protein of the two is highly homologous, which is the virus with the highest homology of successful isolation and culture so far.
The inventor also built a model based on this pangolin coronavirus xcov to screen and evaluate active drugs and vaccines against novel coronavirus.
In addition, as the top priority of new drug research and development, stephanine still lacks human clinical trials. In the industry, the median duration of clinical trials in the field of infection is more than 7 years, and the success rate is less than 20%. There are countless examples of excellent in vitro test results and final clinical smashing.
It is worth mentioning that Tong Yigang, the first inventor of the patent and Dean of the school of life science and technology of Beijing University of chemical technology, stressed in a live broadcast that the report of stephanine had been reported more than two years ago, and there was no response at that time. I didn't expect that the report of the patent attracted so much attention, which may be related to the current epidemic situation. This is a coincidence, which led to the rise of some stocks.
