Autor: Akira Nakagawa, Hiroshi Sano, Sadayoshi Satsumabayashi, Satoshi Omura, Kiyoshi Shibata, Kanki Komiyama
Publikováno v: The Journal of Antibiotics. 41:614-623
Several acyl derivatives of hitachimycin have been synthesized and their activities, including antibacterial, cytocidal against HeLa cells and in vivo antitumor against sarcoma 180, evaluated. Some of these derivatives showed higher antitumor activit
