Scientists identify six potential drugs to treat Covid19

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.

Tehran, Mar 15: Two hundred and thirty-four Indians stranded in coronavirus-hit Iran have arrived in India, External Affairs Minister S Jaishankar said on Sunday.

The batch comprises 131 students and 103 pilgrims, he said.

“234 Indians stranded in Iran have arrived in India; including 131 students and 103 pilgrims. Thank you Ambassador Dhamu Gaddam and @India_in_Iran team for your efforts. Thank Iranian authorities,” Jaishankar tweeted.

The third batch of Indians from Iran arrived early Sunday. A second batch of 44 Indian pilgrims had arrived from Iran on Friday.

Iran is one of the worst-affected countries by the coronavirus outbreak and the government has been working on plans to bring back Indians stranded there.

The first batch of 58 Indian pilgrims were brought back from Iran on Tuesday.

Beijing/Wuhan, Apr 17: China's coronavirus death toll mounted to 4,632 on Friday as the country revised figures in its epicentre Wuhan with 1,290 additional fatalities amid international criticism of under-reporting of COVID-19 data.

The Wuhan municipal headquarters on Friday revised the number of confirmed COVID-19 cases and deaths due to the disease, state-run Xinhua news agency reported.

As of April 16, the total number of confirmed coronavirus cases in Wuhan was increased by 325 to 50,333 and the number of fatalities up by 1,290 to 3,869.

The revised figure raised China's overall COVID-19 death toll to 4,632. The total number of cases also increased to 82,692.

The Wuhan municipal headquarters in a notification said the revisions were made in accordance with related laws and regulations as well as the principle of being responsible for history, the people and the deceased.

The revision of figures came amid sharp criticism of China by the US and other nations for its alleged under-reporting of the coronavirus cases and cover-up of the origin of the viral strain, which emerged in Wuhan in December last, reportedly from the local Hunan sea food market.

Explaining the reason for the figure revision, the Wuhan municipality said it was done to ensure that the information on the city's COVID-19 epidemic is open and transparent, and that the data are accurate.

Listing the reasons for the data discrepancies, it said the surging number of patients at the early stage of the epidemic overwhelmed medical resources and the admission capacity of medical institutions. Some patients died at home without having been treated in hospitals.

Besides, during the height of their treating efforts, hospitals were operating beyond their capacities and medical staff were preoccupied with saving and treating patients, resulting in belated, missed and mistaken reporting.

Also, due to a rapid increase of designated hospitals for treating COVID-19 patients -- including those administered by ministries, Hubei Province, Wuhan city and its districts, those affiliated to companies, as well as private hospitals and makeshift hospitals -- a few medical institutions were not linked to the epidemic information network and failed to report their data in time.

The registered information of some of the deceased patients was incomplete, and there were repetitions and mistakes in the reporting, the Wuhan authorities noted.

Citing an official of the Wuhan municipal headquarters, Xinhua reported that a group for epidemic-related big data and epidemiological investigations was established in late March.

The group used information from online systems and collected full information from all epidemic-related locations to ensure that facts about every case are accurate and every figure is objective and correct.

"What lie behind the epidemic data are the lives and health of the general public, as well as the credibility of the government," the official was quoted by the report.

The timely revision of the figures, among other things, shows respect for every single life, the official said.

Meanwhile, the revised cases were not included in the overall national figures released by China's National Commission (NHC) in its daily report on Friday as it reports previous day's cases.

As per NHC data, as of Thursday the overall confirmed cases of coronavirus was 82,367, including 3,342 deaths.

As many as 1,081 patients are being treated and 77,944 people discharged after recovery, it said.

NHC said it received reports of 26 new confirmed COVID-19 cases from the mainland on Thursday, of which 15 were imported.

The other 11 new cases were domestically transmitted, it said, noting that five cases were reported in Guangdong Province, three in Heilongjiang Province, two in Shandong Province and one in Liaoning Province.

No death was reported on Thursday on the mainland.

As of Thursday, China has a total of 1,549 imported cases, NHC said, adding that 879 were undergoing treatment with 45 in severe condition. Besides, there were 66 new asymptomatic cases, taking the tally to 1,038.
