Research Abstract

For creation of a new antitumor drug targeting the interactions between tumor cells and the surrounding stromal cells in tumor tissues, we have developed coculture systems of both cells and searched for compounds that modulate the interactions. As a result, we have isolated a new compound, intervenolin, from the culture broth of actinomyces. Intervenolin inhibits the growth of human gastric and colorectal cancer cell lines when cocultured with the respective organ-derived stromal cells more strongly than that of the cancer cells cultured alone. Intervenolin shows antitumor effects against xenograft models of human gastric and colorectal cancer cells in vivo.
