Here are 69 potential Antiviral drug treatments as the Coronovirus rips up South Africa

HERE are 69 possible antiviral drug treatments for the Coronovirus. Some of them repurpose old drugs, others involve new combinations, and are already in use for a range of diseases, including Parkinsons, Cancer and HIV. Some drugs have already been approved for administering by doctors, some are already in preclinical trials. Among them is a 1971 antiviral drug, Ribavirin capable of disrupting the RNA synthesis of the coronovirus itself, the bug responsible for the biggest health crisis event of the 21st Century.

The drug is described in a paper aptly entitled ‘Broad-spectrum coronavirus antiviral drug discovery‘. It escaped media attention, perhaps due to its patent rights lapsing, while Lopinavir–Ritonavir, a relatively new HIV drug received a lot of press, alongside Favivlavr a drug from China approved by the National Medical Products Administration of China .

It appears a massive search using the latest information technology and supercomputers was conducted.

A group of scientists including ‘Computational Medicine and Bioinformatics’ experts has raced to make the discovery as New York hits an epidemic spike that looks set to require at least 30 000 extra respirators, countless more hospital beds, and the construction of makeshift morgues. The City is currently in a state of emergency.

South Africa is about to enter a national lockdown from midnight Thursday.

The latest research dovetails a paper published on 27 February by Micholas Smith, Jeremy C. Smith on ‘Repurposing Therapeutics for COVID-19: Supercomputer-Based Docking to the SARS-CoV-2 Viral Spike Protein and Viral Spike Protein-Human ACE2 Interface.’

The newer paper was published on 22 March 2020 and should have made headline news, if only NYC wasn’t at the centre of the epidemic.

The list includes Chloroquine, a controversial anti-malaria drug with a low Lethal Dose 50 (LD50), a measure of toxicity, where low is more toxic. The drug has been touted by Donald Trump, but has not been approved by the FDA for use, and also Haloperidol, a drug used to treat so-called Schizophrenia.

Meanwhile the World Health Organisation (WHO) has launched a global megatrial of what it claims are ‘the four most promising coronavirus treatments’

Scientists in Iceland have found 40 mutations of the coronavirus among people with the deadly bug in the country. A previous study conducted in China and published early this month indicates that two separate types of the novel coronavirus — one more aggressive than the other — had been infecting people since the start of the outbreak.

According to a WHO official ‘Ten percent of the people who are in [intensive care units] in Italy are in their 20s, 30s or 40s. These are young, healthy people with no co-morbidities, no other diseases.’
