The invention relates to antibiotic derivatives of formula I
wherein:
A represents —O—, S, —C(═O)—, —C(═NOR6)—;
Z—B represents NCH2CH2, NCOCH2, NCH2CO, NCH2CH(OH), CHN(R8)CH2 or CHN(R8)CO;
D represents binuclear heteroaryl;
Y1 represents —CR1— or —N—, Y2 represents —CR2— or —N—, Y3 represents —CR3— or —N— and
Y4 represents —CR4— or —N—;
U represents —NH—, —O— or —S— and V represents —N— or —CH—;
W represents —CH2—, —O— or —NR7—;
R1 represents H, methyl, ethyl or halogen;
R2, R3 and R4 each represent independently H, C1-C4 alkyl, halogen, or C1-C4 alkoxy;
R5 represents H, C1-C4 alkyl or fluorine;
R6 represents H, C1-C4 alkyl or aryl-C1-C4 alkyl;
R7 represents H, C1-C4 alkyl, aryl-C1-C4 alkyl or —CH2—COOH;
R8 represents H, C1-C4 alkyl or —CH2—COOH;
with the provisos that
if Z—B represents NCH2CH2, NCOCH2, NCH2CO or NCH2CH(OH), then W represents —CH2—;
if A represents O or S, then W represents —CH2—; and
only one or two of Y1, Y2, Y3 and Y4 can represent N at the same time.
