SCH 38057 (1-[6-(2-chloro-4-methoxyphenoxy)-hexyl]imidazole hydrochloride) is a new, water-soluble antiviral compound that has inhibitory activities against a number of picornavirus infections. The structure of the human rhinovirus 14 (HRV14) complex with SCH 38057 was determined at 3.0 A resolution by single-crystal diffraction techniques using synchrotron X-radiation. SCH 38057 was found to bind at the innermost end of the hydrophobic pocket within the capsid protein VP1, a locus of binding of other antipicornaviral agents; however, the complex differs from previously reported complexes in two important aspects. It leaves a considerable volume near the entrance to the binding pocket unoccupied. In addition, the alterations in the conformation of the VP1 polypeptide are similar to, but more extensive than those observed in HRV14 complexes with other antiviral agents. Although only 9 amino acids of VP1 have close contacts with the SCH 38057 molecule (within 3.6 A), at least 36 amino acids from both VP1 and VP3 have significantly altered conformations (C alpha movement > 0.5 A versus native). The structures of complexes of HRV14 with SCH 38057 and WIN 51711 are compared. Aromatic ring interactions between picornavirus capsid residues and antiviral inhibitors are proposed to be among the major determinants for positioning of these compounds.
