Figure 5: Detail interaction structure of both selected ligands, Pralatrexate bound to the LA binding pocket in spike protein. Represent selexipag bound to the bound to the LA binding pocket in spike protein B chain. bound to the LA binding pocket in spike protein. The green surface structure and helix represent the A chain and gray surface structure represent the B chain. Pralatrexate is represented in purple and selexipag in Red. LA: Linoleic acid
