Emerging antiviral drugs in plant chemotherapy
In medical research, the strategic design of drugs directed to specific viral targets appears an expanding chemotherapic approach. In this field, neuraminidase (NA) and inosine monophosphate dehydrogenase (IMPDH) are two key enzymes, whose inhibition may be expected to effect viral RNA. Oseltamivir...
