Intervenolin is a natural antitumor quinolone that inhibits the growth of MKN-74 gastric tumor cells cocultured with Hs738 gastric stromal cells, and exhibits selective anti-Helicobacter pylori activities. In this report, a structure activity relationship study of intervenolin is presented. Suitable substituents on the nitrogen, including iminodithiocarbonate moiety, alleviated acute toxicity, and four derivatives displayed specific anti-H. pylori activity. One intervenolin analog with quinoline scaffold also exhibited selective growth inhibition toward cocultured MKN-74, and in vivo antitumor effect. (C) 2013 Elsevier Ltd. All rights reserved.
