Binding of synthetic carbohydrate receptors to enveloped virus glycans: Insights from molecular dynamics simulations.

ABSTRACT: Can envelope glycans be targeted to stop viral pandemics? Here we address this question by using molecular dynamics simulations to study the binding between 10 synthetic carbohydrate receptors (SCRs) and the 33 N-glycans most commonly found on the surfaces of enveloped viruses, including Zika virus and SARS-CoV-2. Based on association quotients derived from these simulations, we classified the SCRs as weak binders, promiscuous binders, or selective binders. The SCRs almost exclusively associate at the Man₃GlcNAc₂ core, which is common to all N-glycans, but the binding affinity between the SCR⋅glycan pair depends on the noncovalent interactions between the heterocycle rings and the glycan antennae. Systematic variations in the glycan and SCR structures reveal relations
