Pharmacophore Modelling Analysis and Synthesis of Vanillin Derivatives as Neuraminidase Inhibitors of Influenza Virus and 3CLpro Inhibitors of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV)

Influenza remain as global threat and public health concern over the years. For the past century, there were a number of significant influenza pandemics recorded, which were H1N1 Spanish flu (1918), the H2N2 Asian flu (1957), the H3N2 Hong Kong flu (1968), and the H1N1 swine flu (2009). Despite the...
