By Pete Farley Plitidepsin was 27.5-fold more potent against SARS-CoV-2 than remdesivir, a drug that received FDA emergency use authorization in 2020 for the treatment of COVID-19, according to new research. Image by NIH Scientists at UC San Francisco’s Quantitative Bioscience Institute (QBI) and the Icahn School of Medicine at Mt. Sinai (ISMMS) in New York have shown that plitidepsin...
by John Hewitt , Medical Xpress Credit: National Institute of Neurological Disorders and Stroke, NIH One of the early indicators of imminent SARS-CoV-2 infection is a sudden and complete loss of smell and taste. Often, these symptoms persist long after infection has been seemingly cleared. How might a virus like this get into the nervous...
AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE Researchers have engineered an antibody that neutralizes SARS-CoV-2 with a potency that “rivals” current lead SARS-CoV-2 clinical neutralizing antibodies, and that also broadly neutralizes a range of clade 1 sarbecoviruses. Their antibody, ADG-2, studied in mice, represents a “promising candidate” for the prevention and treatment of not only COVID-19,...

As scientists identify more and more potentially worrying variants of the coronavirus SARS-CoV-2, they are grappling with just what to call them. At a 12 January World Health Organization...
By Sally Robertson, B.Sc. Jan 11 2021 Researchers in the United States have shown that extracts of an aromatic herb called Artemisia annua inhibit the replication of severe acute respiratory coronavirus (SARS-CoV-2) – the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic. Also known as “Sweet wormwood,” Artemisia annua (A. annua) is an herb from Asia that produces...
By Dr. Sanchari Sinha Dutta, Ph.D. Jan 11 2021 A double-blind, randomized, placebo-controlled clinical trial conducted at the All India Institute of Medical Sciences, India, has recently demonstrated that Ivermectin, an anti-parasitic drug, can reduce in-hospital mortality rate of coronavirus disease 2019 (COVID-19) patients. The study is currently available on the medRxiv* preprint server. Study: Ivermectin as a...
There is some onward transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from household contacts released from quarantine after seven or 10 days, according to research published in the Jan. 1 issue of the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report. Melissa A. Rolfes, Ph.D., from the CDC COVID-19 Response...

By Dr. Sanchari Sinha Dutta, Ph.D. Jan 6 2021 A team of scientists from the University of Saskatchewan, Canada, has recently demonstrated that chemical agents capable of reducing disulfide (S-S) bonds can be potentially used as antiviral drugs against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19). Their...
