Amiloride derivatives are known blockers of the cellular Na(+)/H(+) exchanger and the epithelial Na(+) channel. More recent studies demonstrate that they also inhibit ion channels formed by a number of viral proteins. We previously reported that 5-(N-ethyl-N-isopropyl)amiloride (EIPA) modestly inhibits intracellular replication and, to a larger extent, release of human rhinovirus 2 (HRV2) (E. V. Gazina, D. N. Harrison, M. Jefferies, H. Tan, D. Williams, D. A. Anderson and S. Petrou, Antiviral Res. 67:98-106, 2005). Here, we demonstrate that amiloride and EIPA strongly inhibit coxsackievirus B3 (CVB3) RNA replication and do not inhibit CVB3 release, in contrast to our previous findings on HRV..
