Abstract:
Thanks to the pioneering work done by Professor Hamao Umezawa, bioactive compounds have been used in treatment of several diseases including cancer. In this review, we discuss our work, which focuses on developing new candidates for anti-tumor drugs by screening for bioactive natural compounds in microbial cultures using unique experimental systems. We summarize our recent progress including the following: (1) small-molecule modulators of tumor-stromal cell interactions, (2) inhibitors of three-dimensional spheroid formation of cancer cells, (3) multi-cancer cell panel screening and (4) new experimental animal models for cancer metastasis.The Journal of Antibiotics advance online publication, 30 August 2017; doi:10.1038/ja.2017.97.
