With new data in hand, our first preprint on SARS-cov-2 receptor binding domain (RBD) interacting with heparin now has a sibling, which demonstrates that heparin inhibits the infection of Vero cells by SARS-cov-2

Some of the key points of the team’s new work are:

  1. Inhibition of viral infectivity in a Vero cell model by heparin, which is a better inhibitor for SARS-cov-2 than SARS-cov.
  2. Analysis of the interactions of a more extended library of model heparins with the SARS-cov-2 receptor binding domain. As with many other heparin-binding proteins, these data show that while sulfation is critical for RBD binding, the amount of sulfate is not, but instead it is the spatial arrangement of sulfate groups that is most important.

Together the data point to heparin being a potentially useful therapeutic to reduce infectivity. (more…)
