Inhibition of coronavirus spike protein binding to ACE2

A novel coronavirus, CoV-19, and a later phenotype CoV-2 were identified as the primary cause for severe acute respiratory syndrome (SARS CoV-2). The spike (S) protein of CoV-2 is one target for the development of a vaccine to prevent the viral entry into human cells. The inhibition of the direct interaction between ACE2 and the S-protein could provides a suitable strategy to prevent the membrane fusion of CoV-2 and the viral entry into human cells. Using MD simulations, we investigate the assembly process of a Coronavirus Spike protein fragment, the hexapeptide YKYRYL on the ACE2 receptor and its inhibitzory effect on the aggregation and activation of the CoV-2 spike receptor protein at the same receptor protein.

Antiviral effects for COVID-19: Early is better

A new study by an international team of researchers and published on the preprint server medRxiv* in June 2020 describes the possible reasons for inconsistent or null findings in clinical studies of antiviral drugs to date. It proposes a new approach to decide the sample size in light of its findings.

A vectored vaccine candidate against SARS-CoV-2

The current pandemic of COVID-19 is caused by the severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), a betacoronavirus similar to that which caused the SARS-CoV and MERS-CoV earlier. Scientists are pursuing therapeutic drugs and vaccines to counter the relentless spread of the virus, but so far, none has been established to be effective. However, several are in clinical trials in various parts of the world.

How comorbidities affect SARS-CoV-2 viral entry

Almost from the start of the current COVID-19 pandemic, it has become clear that individuals suffering from other medical conditions like diabetes, cardiovascular disease, and lung disease are far more likely to contract the infection and to have a poorer outcome.

A closer look at TMPRSS2: This could help treat COVID-19

The transmembrane protease serine-type 2 (TMPRSS2) protein plays a key role in COVID-19 infection since it primes the viral spike protein to allow viral entry into the target cell. A new study by researchers at Imperial College London and published on the preprint server bioRxiv in May 2020 describes the protein, which could be an attractive drug target to help manage COVID-19.
