We found that 1,4-naphthoquinone was rapidly internalized by the cells.

This is the first report demonstrating that 2-methoxy-1,4-naphthoquinone has intensive in vitro anti-tumor activity against HepG2 cells.

We describe here the utilization of 1,4-naphthoquinone and 3-iodo-1,4-naphthoquinone motifs as new anion binding sites by hydrogen- or halogen-bonding interactions, respectively.

The aim of this study was to screen compounds with potential activity against dengue virus from a library of synthetic naphthoquinones.

It was also demonstrated that nitroxides exert two opposing effects on exonuclease III deficient cells of Escherichia coli upon exposure to naphthoquinones.
