CSIRO’s new drug to tackle all flu strains

The new drug, which is still in development, acts by preventing the flu virus from removing sialic acids attached to the cell surface, thereby preventing the virus from infecting more cells.

The drug, a neuraminidase inhibitor, stops flu virus spread because it is more closely related to the surface sialic acids it digests than the existing neuraminidase inhibitors oseltamivir (Tamiflu) and zanamivir (Relenza), to which drug-resistant strains of flu are now emerging, the scientists say.
