Virus-cell fusion inhibitory activity for the polysaccharides from various Korean edible clams

Research Article Medicinal Chemistry & Natural Products


In order to find potent virus-cell fusion inhibitory components from Korean edible clams, thirteen prepared polysaccharides were introduced to syncytia formation inhibition assay, which is based on the interaction between the HIV-1 envelope protein gp120/41 and the cellular membrane protein CD4 of T lymphocytes. Among them,Meretrix petechialis showed a potent viruscell fusion inhibitory activity. Fusion index (FI) and percent (%) fusion inhibition of the polysaccharide of this clam were 0.21 ±0.02, and 67.52±4.09 at 100μg/ml, respectively. It exhibited almost equivalent virus-cell fusion inhibitory activity to that of dextran sulfate which was used as a standard control.
