Table 1. Binding Kinetics and Dissociation Constants (KD) for the Nine SARS-CoV-2 RBD Cyclic Peptide Ligands Synthesized and Evaluated against the RBD by SPRa.
* peptides contain C-terminal hexaethylene glycol moieties; # refractive index values high on sensorgram; NSB = nonspecific binding (see the Supporting Information for sensorgrams).
