    Product Description

    Vapendavir is a capsid-binding antiviral agent.1,2 It binds to a pocket in the human rhinovirus (HRV) strain HRV2 VP1 capsid protein and inhibits the cytopathic effects of HRV2 and HRV14 in HeLa Ohio cells (EC50s = 1 and 5 ng/ml, respectively), as well as in a panel of 39 HRV clinical isolates (median EC50 = 7.3 ng/ml).1 Vapendavir inhibits replication in a panel of 21 enterovirus 71 (EV71) isolates with an average EC50 value of 0.7 μM.2
