National Yang Ming Chiao Tung University researchers have identified four antiviral drug candidates that can inhibit SARS-CoV-2, which causes COVID-19, the team leader said on Tuesday.
One of the drug candidates — JMY206 — is more than 10 times stronger than remdesivir, the first antiviral drug fully certified for the treatment of COVID-19, said Yang Jinn-moon (楊進木), dean of the university’s College of Biological Science and Technology.
The other drugs identified are boceprevir, an oral, direct-acting hepatitis C virus protease inhibitor; telaprevir, a hepatitis C drug; and nelfinavir, an antiretroviral drug used to treat HIV-positive patients, Yang said.

The team’s starting point was its understanding that SARS-CoV-2 is highly similar to the virus that causes SARS, Yang said.
It then gathered SARS-related data and screened US Food and Drug Administration-approved drugs and natural products for possible COVID-19 treatment, he said.
By using artificial intelligence and big data, the team created simulations of changes in cell mechanisms after SARS-CoV-2 entered human host cells, and compared them with 250 globally published images of the 3D architecture of the main protease of the virus.
That resulted in the identification of six possible structures of key proteases — the enzymes that break down proteins and could lead to disease — that are essential for promoting SARS-CoV-2 entry, Yang said.
The team then identified the drugs that could inhibit the proteases and eventually SARS-CoV-2.
The most potent of the drugs, JMY206, can inhibit SARS-CoV-2 from entering cells, the team said.
The therapeutic benefits of JMY206 have also been proven in animal experiments and it can be a potential oral drug against COVID-19, Yang said.
The team has applied for a patent, and is planning to publish a paper on its findings and develop medicines by combining other medicinal components, Yang added.
Thirty-five earthquakes have exceeded 5.5 on the Richter scale so far this year, the most in 14 years, the Central Weather Administration (CWA) said on Facebook on Thursday. A large earthquake in Hualien County on April 3 released five times as much the energy as the 921 Earthquake on Sept. 21, 1999, the agency said in its latest earthquake report for this year. Hualien County has had the most national earthquake alerts so far this year at 64, with Yilan County second with 23 and Changhua County third with nine, the agency said. The April 3 earthquake was what caused the increase in
INTIMIDATION: In addition to the likely military drills near Taiwan, China has also been waging a disinformation campaign to sow division between Taiwan and the US Beijing is poised to encircle Taiwan proper in military exercise “Joint Sword-2024C,” starting today or tomorrow, as President William Lai (賴清德) returns from his visit to diplomatic allies in the Pacific, a national security official said yesterday. Commenting on condition of anonymity, the official said that multiple intelligence sources showed that China is “highly likely” to launch new drills around Taiwan. Although the drills’ scale is unknown, there is little doubt that they are part of the military activities China initiated before Lai’s departure, they said. Beijing at the same time is conducting information warfare by fanning skepticism of the US and
Chinese President Xi Jinping (習近平) is unlikely to attempt an invasion of Taiwan during US president-elect Donald Trump’s time in office, Taiwanese and foreign academics said on Friday. Trump is set to begin his second term early next year. Xi’s ambition to establish China as a “true world power” has intensified over the years, but he would not initiate an invasion of Taiwan “in the near future,” as his top priority is to maintain the regime and his power, not unification, Tokyo Woman’s Christian University distinguished visiting professor and contemporary Chinese politics expert Akio Takahara said. Takahara made the comment at a
DEFENSE: This month’s shipment of 38 modern M1A2T tanks would begin to replace the US-made M60A3 and indigenous CM11 tanks, whose designs date to the 1980s The M1A2T tanks that Taiwan expects to take delivery of later this month are to spark a “qualitative leap” in the operational capabilities of the nation’s armored forces, a retired general told the Liberty Times (sister paper of the Taipei Times) in an interview published yesterday. On Tuesday, the army in a statement said it anticipates receiving the first batch of 38 M1A2T Abrams main battle tanks from the US, out of 108 tanks ordered, in the coming weeks. The M1 Abrams main battle tank is a generation ahead of the Taiwanese army’s US-made M60A3 and indigenously developed CM11 tanks, which have
