Colombia air crash death toll rises to 76: police

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, May 27: The number of confirmed cases of COVID-19 worldwide has increased by nearly 100,000 over the past 24 hours to surpass 5.4 million, the World Health Organisation (WHO) said.

According to the WHO, the global case tally currently stands at 5,404,512 -- a rise by 99,780 over the past day.

The death count worldwide amounts to 343,514 -- an increase by 1,486.

Most cases of infection are recorded in the Americas -- 2,454,452, with 143,739 deaths.

London, Jun 19: Malala Yousafzai, the youngest Nobel Peace Prize winner who once took a bullet for campaigning for girls' education in Pakistan, was over the moon on Friday after completing her degree in Philosophy, Politics and Economics at Britain's prestigious Oxford University.

Malala, 22, who attended Oxford's Lady Margaret Hall college, took to Twitter to share two pictures that show her celebrating the milestone with her family.

"Hard to express my joy and gratitude right now as I completed my Philosophy, Politics and Economics degree at Oxford," she said in the tweet, accompanied by two pictures - one showing her sitting with her family in front of a cake that says: 'Happy Graduation Malala', and the other in which she is covered with cake smiling for the camera.

In the tweet, the famed human rights activist also revealed her plans for the immediate future - Netflix, reading and sleeping.

"I don't know what's ahead. For now, it will be Netflix, reading and sleep," she wrote.

Malala was shot in the head by the Taliban militants in December 2012 for campaigning for female education in the Swat Valley in northeastern Pakistan.

Severely wounded, she was airlifted from one military hospital in Pakistan to another and later flown to the UK for treatment.

After the attack, the Taliban released a statement saying that they would target Malala again if she survived.

At the age of 17, Malala became the youngest recipient of the Nobel Peace Prize for her education advocacy in 2014 when she shared the coveted honour with India's social activist Kailash Satyarthi.

Unable to return to Pakistan after her recovery, she moved to Britain, setting up the Malala Fund and supporting local education advocacy groups with a focus on Pakistan, Nigeria, Jordan, Syria and Kenya.

The Taliban, who are against girls' education, have destroyed many schools in Pakistan.
