Structural analogs of triterpenoids show strong inhibitory activity against coronaviruses

In a recent study published in the journal Pathogens, researchers carried out a molecular docking study for 17 structural analogs prepared from natural maslinic and oleanolic acids and screened them against SARS-CoV-2 main protease. They also experimentally validated the data by determining the half-maximal cytotoxic and inhibitory concentrations of each of the 17 compounds. The researchers investigated whether the compound with antiviral activity affected viral adsorption, replication, or viricidal effect using a plaque infectivity reduction assay.

People who received Pfizer-Biontech vaccine have lower antibody levels targeting the delta variant

Levels of antibodies in the blood of vaccinated people that are able to recognise and fight the new SARS-CoV-2 Delta variant first discovered in India (B.1.617.2) are on average lower than those against previously circulating variants in the UK, according to new laboratory data from the Francis Crick Institute and the National Institute for Health Research (NIHR) UCLH Biomedical Research Centre, published today (Thursday) as a Research letter in The Lancet.

Study compares Pfizer and Moderna mRNA vaccine-elicited response to SARS-CoV-2 variants

A new study has been published on the bioRxiv preprint server which focuses on the correlation between the vaccine-triggered Immunoglobulin G (IgG) levels and neutralization titers against SARS-CoV-2 variants. Further, neutralization activities against the variants (B.1.1.7, B.1.525, and B.1.351), using Pfizer or Moderna vaccine, sera were assessed.
