Potent inhibition of enterovirus D68 and human rhinoviruses by dipeptidyl aldehydes and α-ketoamides.

ABSTRACT: Enterovirus D68 (EV-D68) is an emerging pathogen responsible for mild to severe respiratory infections that occur mostly in infants, children and teenagers. EV-D68, one of more than 100 non-polio enteroviruses, is acid-labile and biologically similar to human rhinoviruses (HRV) (originally classified as HRV87). However, there is no approved preventive or therapeutic measure against EV-D68, HRV, or other enteroviruses. In this study, we evaluated the antiviral activity of series of dipeptidyl compounds against EV-D68 and HRV strains, and demonstrated that several peptidyl aldehyde and α-ketoamide peptidyl compounds are potent inhibitors of EV-D68 and HRV strains with high in-vitro therapeutic indices (>1000). One of the α-ketoamide compounds is shown to have favorable pharmacokinetics profi
