Antiviral sugar superballs

superball

It’s not too common to encounter a compound as one above in a paper tagged ‘medicinal chemistry’. But the team of Spanish and French chemists seems not to care too much about rule of 5 or any other rules of thumb that constrain their creativity. Especially when the rationale for compound design was:

it is difficult to make compounds of an adequate size and multivalency to mimic natural systems such as viruses

The ligands dubbed ‘superballs’ are targeting dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN). And the multivalency of ligand-receptor interaction is the key factor of viral infection. Previous state-of-the-art ligands were virus-like particles with 1620 mannoses displayed on their surface. So I guess in this study authors significantly optimized ligand efficiency. Continue reading “Antiviral sugar superballs”
