The 2019 Novel Coronavirus (SARS-CoV-2) is a new virus that emerged in China in late 2019 and quickly jumped into scientific and mainstream news. When facing a potential pandemic, it can be difficult to share information without inducing panic. There’s no doubt that SARS-CoV-2 presents a significant threat to public health, but as with all viruses in their emerging stages, we often find ourselves with more questions than answers. However, through the work of the World Health Organization (WHO), government officials and hardworking scientists worldwide, we can begin to understand some of the details about SARS-CoV-2.Continue reading “What We Know About the 2019 Novel Coronavirus, SARS-CoV-2”
Remdesivir (RDV or GS-5734) was used in the treatment of the first case of the SARS-CoV-2 (formerly 2019-nCoV ) in the United States (1). RDV is not an approved drug in any country but has been requested by a number of agencies worldwide to help combat the SARS-CoV-2 virus (2). RDV is an adenine nucleotide monophosphate analog demonstrated to inhibit Ebola virus replication (3). RDV is bioactivated to the triphosphate form within cells and acts as an alternative substrate for the replication-necessary RNA dependent RNA polymerase (RdRp). Incorporation of the analog results in early termination of the primer extension product resulting in the inhibition.
Why all the interest in RDV as a treatment for SARS-CoV-2 ? Much of the interest in RDV is due to a series of studies performed by collaborating groups at the University of North Carolina Chapel Hill (Ralph S. Baric’s lab) and Vanderbilit University Medical Center (Mark R. Denison’s lab) in collaboration with Gilead Sciences.Continue reading “Investigation of Remdesivir as a Possible Treatment for SARS-2-CoV (2019-nCoV)”
