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.

Geneva, Jul 2: The World Health Organization (WHO) has estimated the overall number of coronavirus cases globally at 10,357,662, with 508,055 people having died from the disease.

The UN health agency said in the situation report published on late Wednesday that 163,939 new cases had been recorded in the past day, while further 4,188 patients had died.

Americas continue to lead the count with over 5.2 million cases, followed by Europe with more than 2.7 million.

The WHO declared the COVID-19 outbreak a pandemic on March 11.

Washington, Jul 21: Democrat Joe Biden urged Muslim Americans on Monday to join him in the fight to defeat President Donald Trump as he addressed an online summit hosted by the advocacy organisation Emgage Action to mobilise Muslim voters ahead of the presidential election.

I want to earn your vote not just because he's not worthy of being president, the presumptive presidential nominee told participants.

I want to work in partnership with you, make sure your voices are included in the decision-making process as we work to rebuild our nation.

Biden also reiterated a pledge to overturn a Trump administration ban on travelers from several predominantly Muslim countries, calling it vile.

Wa'el Alzayat, CEO of Emgage Action, said by email that the organisation was seeking to maximise Muslim American turnout in key battleground states.

In Michigan alone one of the states where the organisation has chapters and where Trump won in 2016 by fewer than 11,000 votes he said he believed there are more than 150,000 registered Muslim voters.

Several prominent Muslim American elected officials endorsed Biden for president in a letter organised by Emgage Action ahead of the summit.

Among those who signed the letter are Minnesota Rep. Ilhan Omar, Minnesota Attorney General Keith Ellison and Indiana Rep. Andre Carson, all Democrats.

Omar, one of the first Muslim women elected to Congress, served as a high-profile surrogate for Bernie Sanders before he exited the presidential race in April making her support for Biden potentially helpful as the former vice president seeks to mobilise Muslim voters this fall.

Muslim American voices matter to our communities, to our country, Biden said.

But we all know that your voice hasn't always gotten recognised or represented.

Emgage Action has titled the event Million Muslim Votes, underscoring its emphasis on boosting Muslim turnout in November.

Joe Biden's presence serves not only to galvanise Muslim Americans to cast their ballots, but to usher in an era of engaging with Muslim American communities under a Biden administration, Alzayat said by email before the summit.

The pro-Biden letter from Muslim American elected officials decried a number of Trump's domestic and international policies, including his administration's travel ban and his pullout from the Iran nuclear deal.

A Biden administration will move the nation forward on many of the issues we care about, the letter said, citing racial justice, affordable health care, climate change and immigration.

The Muslim American officials also praised Biden's agenda for their communities.

Among other goals, Biden has vowed to rescind the travel ban affecting Muslims on Day One if he's elected.

In his address, he pledged to include Muslim American voices in his administration, if elected, and to speak out against human rights abuses against Muslim minorities around the world.

I'll continue to champion the rights of Palestinians and Israelis to have a state of their own as I have for decades, each of them a state of their own, he said.

Other state- and local-level Muslim American officials signing onto the pro-Biden letter hail from several states, including Michigan.
