Picornaviruses, such as the structurally related polioviruses and rhinoviruses, are important human pathogens which have been the target of major drug development efforts. Receptor-mediated uncoating and thermal inactivation of poliovirus and rhinovirus are inhibited by agents that bind to each virus by inserting into a pocket in the beta barrel of the viral capsid protein, VP1. This pocket, which is normally empty in human rhinovirus-14 (HRV14), is occupied by an unknown natural ligand in poliovirus. Structural studies of HRV14-drug complexes have shown that drug binding causes large, localized changes in the conformation of VP1.
