Synthesis and anti HSV-1 evaluation of novel indole-3,4-diones

A novel class of water soluble indole-3,4-diones has been synthesized and evaluated in vitro for antiviral activity against HSV-1. The results showed lack of cytotoxicity and significant antiviral activity. The cellular internalization efficiency and the antiherpetic effect were successfully increased by incorporation into nanoaggregates of an amphiphilic b-cyclodextrin.
