claim: sulfated polysaccharides effectively inhibit sars-cov-2 in vitro
evidence_1: our results reveal that specific sulfated polysaccharides bind tightly to the s-protein of sars-cov-2 in vitro, which suggests that they can act as decoys to interfere with s-protein binding to the heparan sulfate co-receptor in host tissues3,11, inhibiting viral infection.", "vero cells were infected with sars-cov-2 at a multiplicity of infection (moi) of 2.5 × 103 with varying dosages of polysaccharide to confirm antiviral activity.")
