Chemical modification of hitachimycin: III. Synthesis and antitumor activities of amino acyl derivatives

Abstract

Amino acyl derivatives of hitachimycin have been synthesized and evaluated their activities including antibacterial, cytocidal against HeLa cells and in vivo antitumor against sarcoma 180. 15-O-(tertButoxycarbonyl(BOC)-glycyl)hitachimycin (2), 15-O-(BOC-β-alanyl)hitachimycin (4), 15-O-(BOC-(O-tert-Bu)-glutamyl)hitachimycin (6) and 15-O-L-alanylhitachimycin (11) showed comparable in vivo antitumor activity with hitachimycin and the solubility of these compounds was improved. © 1989, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION.
