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.

New Delhi, April 6: The United States has donated $2.9 million assistance package for India to help the Narendra Modi government brace itself against the coronavirus as countries across the world are coming together to combat the outbreak.

On March 28, the US government, via US Agency for International Development, announced $2.9 million to support India in its response to COVID-19.

"It builds on a foundation of over $1.4 billion in health assistance and nearly $3 billion in total assistance that the US provided to India over the last 20 years," the US Embassy in India said in a statement.

"These new funds will support two organisations, including $2.4 million for USAID's health strengthening project, implemented by Jhpiego, an international non-profit health organisation affiliated with Johns Hopkins University and $500,000 for the World Health Organization (WHO)," the statement said.

The funds will also help India combat the spread of COVID-19, provide care for the affected and support local communities with the tools needed to contain the disease, it added.

Moreover, being a global leader in health and humanitarian response to COVID-19, the US has provided approximately $18.3 million assistance package to ASEAN member countries to fight the contagion.

The funds will be used to prepare laboratories for large-scale testing for the lethal virus, infection prevention and control, enable risk communication, implement public-health emergency plans for border points of entry, activate case-finding and event-based surveillance for influenza-like illnesses, train and equip rapid-responders in investigation and contact-tracing and update training materials for health workers.

New Delhi, Mar 19: The total number of reported novel coronavirus cases in India has climbed to 169, with 30 fresh cases reported from various parts of the country on Wednesday.

In Maharashtra, a 21-year-old man in Pimpri Chinchwad with travel history to the Philippines, Singapore and Colombo has tested positive for coronavirus. One more person in Ratnagiri has tested positive for Covid-19.

Telangana has reported seven more confirmed coronavirus cases. All the seven are Indonesian national.

Delhi has so far reported 10 positive cases which include one foreigner while Uttar Pradesh has recorded 16 cases, including one foreigner. A man from Noida tested positive on Wednesday, taking the total number to four in Noida.

Karnataka reported two fresh cases on Wednesday, taking the number of infections to 13. The number of cases in Ladakh rose to eight and Jammu and Kashmir three. Telangana has reported six cases which include two foreigners.

One more person has tested positive for coronavirus in Kashmir. The person, with foreign travel history, has been put under isolation. He had arrived in J&K on March 16.

There will be restrictions on public transport, assembly of people and some other measures, in #Srinagar from tomorrow.

Rajasthan has also reported four cases including that of two foreigners. Tamil Nadu, Andhra Pradesh, Odisha, Uttarakhand and Punjab have reported one case each.

Tamil Nadu Health Minister C Vijayabaskar has confined the state's second positive case of coronavirus in the state.

The health minister has stated that the condition of the patient is stable and is in observation.

In Haryana, there are 16 cases, which include fourteen foreigners.
