Shishijimicins A-C, novel enediyne antitumor antibiotics from the ascidian Didemnum proliferum(1).
Three new compounds of the enediyne antibiotics, shishijimicins A-C (1-3), have been isolated from the ascidian Didemnum proliferum. They encompass a novel sugar component, which is a conjugation product of a hexose and a beta-carboline, attached to the calicheamicinone aglycone. Their structures have been determined by interpretation of spectral data. Shishijimicins showed extremely potent cytotoxicity against HeLa cells with IC(50) values of 1.8-6.9 pM.
