Abstract There are no effective antiviral drugs to treat hand, foot, and mouth disease. In this study, a series of lycorine derivatives were synthesized and evaluated against enterovirus 71 and coxsackievirus A16 in vitro. Derivatives 7c-m with the phenoxyacyl group at the C-1 position showed higher efficacy and lower toxicity than lycorine. In addition, derivative 7e enhanced the survival rate to
selectivity index (CC50 /EC50 ) of more than 750. The ketones 1-acetyl-2-oxolycorine (EC50 =1.8 μM) and 2-oxolycorine (EC50 =0.5 μM) also exhibited excellent antiviral activities with low cytotoxicity. Structure-activityrelationships for the lycorine derivatives against DENV are discussed. A three-dimensional quantitative structure-activityrelationship model was established by using a comparative molecular-field
