DC-89 derivatives represented by the formula:
wherein X represents hydrogen or C02CH3; and
is
or
wherein Z represents CI or Br; R represents hydrogen, CONR1R2 (in which R1 and R2 independently represent hydrogen, a straight-chain or branched alkyl group having 1 to 4 carbon atoms or phenyl) or
(in which n represents an integer of 0 to 4; R3 represents CH2,
oxygen, N-CH3, or N-CH2CONR1R2 in which R1 and R2 have the same significances as defined above); and W represents hydrogen or
(in which W1 and W2 independently represent hydrogen or OR4 in which R4 represents a straight-chain or branched alkyl or alkenyl group having 1 to 4 carbon atoms), and pharmaceutically acceptable salts thereof have an excellent anti-tumor and antibacterial activity and are expected to be useful as anti-tumor compositions and antibacterial compositions.
