On the evening of March 27, Zhejiang Jingxin Pharmaceutical Co.Ltd(002020) ( Zhejiang Jingxin Pharmaceutical Co.Ltd(002020) ) issued a change announcement to clarify the rumors related to covid-19 drug cooperation. The reporter noted that in addition to Jinglan pharmaceutical, many companies also caused stock price changes due to misinformation related to relevant events, and clarified.
In the announcement, Zhejiang Jingxin Pharmaceutical Co.Ltd(002020) said that in view of the abnormal fluctuation of the company's stock trading, the company checked the relevant matters and noted that there were rumors on the Internet about " Zhejiang Jingxin Pharmaceutical Co.Ltd(002020) API with trifluorobenzoyl chloride covid-19" and " Zhejiang Jingxin Pharmaceutical Co.Ltd(002020) the only target of the key intermediate of yanyeyi / Pfizer covid-19".
The company clarified that Zhejiang Jingxin Pharmaceutical Co.Ltd(002020) APIs are mainly quinolones, statins and psychoneurotics. At present, the company and its subsidiaries have not carried out relevant cooperation with yanye Yiyi pharmaceutical and Pfizer pharmaceutical in the aspect of covid-19 drugs. The 2,4,5-trifluorobenzoyl chloride planned by the company's Shandong base is a key intermediate for the preparation of 2,4,5-trifluorobenzene, and it still needs a certain period to be put into operation, which is expected to have no material impact on the company's performance in 2022.
On March 24, Zhejiang Jingxin Pharmaceutical Co.Ltd(002020) share price rose sharply in the afternoon, sealed the limit board, opened higher the next day, and soon rose again. As of the closing on the 25th, Jinglan pharmaceutical's share price closed at 10.53 yuan / share.
The reporter noted that recently, the epidemic concept has continued to strengthen, intermediates / raw materials have the strongest performance, and yanyeyi's concept has been active. Open source Securities pointed out that yanyeyi covid-19 oral drug s-217622 submitted an application for clinical treatment approval, and the phase 2A clinical results were positive. Among them, after five times of administration, the positive proportion of virus titer in the low-dose s-217622 group was cleared. At present, the raw materials are the focus of the market. According to the analysis of open source securities, one of the main raw materials of covid-19 is 1 - (bromomethyl) - 2,4,5-trifluorobenzene (also known as 3,4,5-trifluorobenzene), which can be obtained by catalytic reduction and bromination of 2,4,5-trifluorobenzaldehyde.
That's why the share prices of many companies involved in the concept rose sharply. However, some companies clarified that they had been misinformed and related events.
