The structure of Rhinovirus 16
Overview
Pleconaril is a broad-spectrum antirhinovirus and antienterovirus compound, that binds into a hydrophobic pocket within viral protein 1, stabilizing, the capsid and resulting in the inhibition of cell attachment and RNA, uncoating. When crystals of human rhinovirus 16 (HRV16) and HRV14 are, incubated with pleconaril, drug occupancy in the binding pocket is lower, than when pleconaril is introduced during assembly prior to, crystallization. This effect is far more marked in HRV16 than in HRV14 and, is more marked with pleconaril than with other compounds. These, observations are consistent with virus yield inhibition studies and, radiolabeled drug binding studies showing that the antiviral effect of, pleconaril against HRV16 is greater on the infectivity of progeny virions, than the parent input viruses. These data suggest that drug integration, into the binding pocket during assembly, or at some other late stage in, virus replication, may contribute to the antiviral activity of capsid, binding compounds.
