In order to search for new antitumor drug candidates from 2-arylnaphthyridin-4-ones (ANs), we have designed and synthesized a series of 3 '-hydroxy or 6-hydroxy derivatives of ANs. Following the antitumor activity screening, most of these compounds were found to exhibit significant activity. Among them, 2-(3-hydroxyphenyl)-5-methyl-1,8-naphthyridin-4(1H)-one (67) was the most promising. In a preliminary action mechanism study, the treatment of Hep3B hepatoma cells with compound (67) reveals that its mechanism of action is affect on microtubule and metastasis-related proteins. Then, the corresponding phosphate prodrug (86) of compound (67) was tested against Hep3B xenograft nude mice model for antitumor activity.
