Melbourne, Apr 10: Scientists have identified six drug candidates from more than 10,000 compounds that may help treat COVID-19.

The research, published in the journal Nature, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

"Currently there are no targeted therapeutics or effective treatment options for COVID-19," said Professor Luke Guddat from the University of Queensland in Australia.

"In order to rapidly discover lead compounds for clinical use, we initiated a programme of high-throughput drug screening, both in laboratories and also using the latest computer software to predict how different drugs bind to the virus," Guddat said.

The project targeted the main COVID-19 virus enzyme, known as the main protease or Mpro, which plays a pivotal role in mediating viral replication, the researchers said.

This makes it an attractive drug target for this virus, and as people don't naturally have this enzyme, compounds that target it are likely to have low toxicity, they said.

"We add the drugs directly to the enzyme or to cell cultures growing the virus and assess how much of each compound is required to stop the enzyme from working or to kill the virus. If the amount is small, then we have a promising compound for further studies," said Guddat.

After assaying thousands of drugs, researchers found of the six that appear to be effective in inhibiting the enzyme, one is of particular interest.

"We're particularly looking at several leads that have been subjected to clinical trials including for the prevention and treatment of various disorders such as cardiovascular diseases, arthritis, stroke, atherosclerosis and cancer," Guddat said.

Researchers said compounds that are already along the pipeline to drug discovery are preferred, as they can be further tested as antivirals at an accelerated rate compared to new drug leads that would have to go through this process from scratch.

"With continued and up-scaled efforts we are optimistic that new candidates can enter the COVID-19 drug discovery pipeline in the near future," Guddat said.

Beijing, May 9: Mounting a strong defence of the ruling Communist Party of China, President Xi Jinping has said the COVID-19 fight has once again shown that the CPC leadership and the country's socialist political system can overcome any challenge.

Xi's comments came as China faced global criticism for its initial inaction to act against the novel coronavirus, which according to Chinese officials emerged in the central Chinese city of Wuhan in December last year.

Pressure is also mounting on Beijing to agree for an international probe on the origins of the vicious virus, including from the Wuhan Institute of Virology (WIV), as claimed by the US leadership.

China curbed the spread of the coronavirus in over a month and brought COVID-19 under control at its first epicentre in Wuhan in about three months, Xi, also the General Secretary of the CPC, said at a symposium held on Friday to get suggestions from non-ruling Communist Party of China (CPC) parties on COVID-19 prevention and control.

He termed the curbing of the COVID-19 pandemic as "hard-won achievements" for the world's most populous country and the second-biggest economy.

The COVID-19 fight has once again shown that the CPC leadership, China's socialist system and its governance system can overcome any challenge and make big contributions to the progress of human civilisation, he said.

Xi said China had basically curbed the spread of the virus in over one month, managed to bring the daily number of new domestically-transmitted cases down to single digits in about two months, and secured decisive achievements in protecting epicentres Wuhan and Hubei province in about three months.

"For a huge country with 1.4 billion people, these are hard-won achievements," he said

Besides the top CPC officials, the symposium was attended by members of the central committees of non-CPC parties in China, the All-China Federation of Industry and Commerce, and persons without party affiliation.

The speakers at the symposium praised the Chinese leadership in handling the crisis, saying it fully demonstrated the political advantage of China's socialist system and showed that China was a major responsible country.

Xi, who is also the head of the People's Liberation Army, praised China's one-party political system governed by the CPC.

His comments on the country's political system came as Beijing is also defending the role of the CPC as US President Donald Trump and Secretary of State Mike Pompeo have blamed the ruling party for not being transparent in the fight against the pandemic.

Both Trump and Pompeo have been pressing Beijing to allow American experts for a probe on whether the virus emerged from the WIV, China's premier research lab where viruses of different types are reportedly researched.

At the symposium attended by the top CPC officials, Xi's leadership came for praise for successfully handling the situation, the state-run Xinhua news agency reported.

"Attendees noted the major strategic achievements in the COVID-19 fight under the strong leadership of the CPC Central Committee with Comrade Xi Jinping at the core," the report said.

The meeting was held amid reports of murmurs of internal criticism within the CPC about Xi's handling of the coronavirus crisis.

While China's move of handling the coronavirus from January 23 by locking down Hubei province and its capital Wuhan to prevent the spread of the virus and curbing it by deploying 42000 medical personnel has been praised, Beijing is criticised for its slow reaction after it emerged in December last year.

China used less than a week to identify the full genome sequence of the novel coronavirus and isolate the virus strain, produced various testing kits and swiftly selected a number of effective drugs and treatments. Different types of vaccines have also entered clinical trials.

President Xi said during the COVID-19 fight, China upheld the centralised and unified leadership of the CPC and concentrated the nation's best doctors, the most advanced equipment and the most needed resources to treat patients, with all treatment expenses covered by the state.

It managed to maximise the testing and cure rates while minimising the infection and fatality rates.

As of Friday, the COVID-19 death toll in China remained at 4,633 with no new fatalities reported for several days while the total number of cases stood at 82,887. In contrast, Chinese officials point out the death toll in the US which has crossed 75,000 with over 1.2 million cases, besides the mounting global toll.

Almost all countries in the world have been under lockdown for weeks to control the spread of the virus.

Xi called for mobilising the whole society, leveraging the institutional strength of concentrating resources to get things done and tapping the composite national strength as well as closely relying on science and technology.

On international cooperation, Xi said China had helped countries and international organisations to the best of its ability, demonstrating the nation's sense of responsibility as a major and responsible country.

Xi also stressed fixing the shortcomings in the country's major epidemic prevention and control mechanism and for the national public health system to raise the ability to deal with major public health emergencies.

He emphasised on targeted and effective measures to guard against the importation of cases and prevent a resurgence of the epidemic.

May 15: Global deaths linked to the novel coronavirus passed 300,000 on Thursday, while reported cases of the virus are approaching 4.5 million, according to a news agency tally.

About half of the fatalities have been reported by the United States, the United Kingdom and Italy.

The first death linked to the disease was reported on January 10 in Wuhan, China. It took 91 days for the death toll to pass 100,000 and a further 16 days to reach 200,000, according to the Reuters tally of official reports from governments. It took 19 days to go from 200,000 to 300,000 deaths.

By comparison, an estimated 400,000 people die annually from malaria, one of the world’s most deadly infectious diseases.

The United States had reported more than 85,000 deaths from the new coronavirus, while the United Kingdom and Italy have reported over 30,000 fatalities each.

While the current trajectory of COVID-19 falls far short of the 1918 Spanish flu, which infected an estimated 500 million people, killing at least 10% of patients, public health experts worry the available data is underplaying the true impact of the pandemic.

Tehran, Jun 29: Iran has issued an arrest warrant and asked Interpol for help in detaining President Donald Trump and dozens of others it believes carried out the drone strike that killed a top Iranian general in Baghdad, a local prosecutor reportedly said Monday.

While Trump faces no danger of arrest, the charges underscore the heightened tensions between Iran and the United States since Trump unilaterally withdrew America from Tehran’s nuclear deal with world powers.

Tehran prosecutor Ali Alqasimehr said Trump and more than 30 others whom Iran accuses of involvement in the Jan. 3 strike that killed Gen. Qassem Soleimani in Baghdad face “murder and terrorism charges,” the semiofficial ISNA news agency reported.

Alqasimehr did not identify anyone else sought other than Trump, but stressed that Iran would continue to pursue his prosecution even after his presidency ends.

Interpol, based in Lyon, France, did not immediately respond to a request for comment.

Alqasimehr also was quoted as saying that Iran requested a “red notice” be put out for Trump and the others, which represents the highest level arrest request issued by Interpol. Local authorities end up making the arrests on behalf of the country that request it. The notices cannot force countries to arrest or extradite suspects, but can put government leaders on the spot and limit suspects’ travel.

After receiving a request, Interpol meets by committee and discusses whether or not to share the information with its member states. Interpol has no requirement for making any of the notices public, though some do get published on its website.

It is unlikely Interpol would grant Iran’s request as its guideline for notices forbids it from “undertaking any intervention or activities of a political” nature.

The U.S. killed Soleimani, who oversaw the Revolutionary Guard’s expeditionary Quds Force, and others in the January strike near Baghdad International Airport. It came after months of incidents raising tensions between the two countries and ultimately saw Iran retaliate with a ballistic missile strike targeting American troops in Iraq.
