The invention concerns compounds of formula (I),
wherein, for example,
R1 is of the formula —NHC(═O)Ra wherein Ra is (1-4C)alkyl;
R2 and R3 are independently hydrogen or fluoro;
R5 and R6 are, for example, hydrogen;
R4 is —X—Y—Het.;
wherein, for example,
X is a direct bond and Y is —(CH2)m— or —CONH—(CH2)m—;
or X is —(CH2)n— and Y is —S(O)p—(CH2)m—;
or X is —CH2O—or —CH2NH— and Y is —CO—(CH2)m—;
wherein n is 1, 2 or 3; m is 0, 1, 2 or 3 and p is 0, 1 or 2;
wherein Het. is a heterocyclic ring, unsaturated or saturated, optionally substituted by, for example, (1-4C)alkyl, halo, cyano, nitro or amino; pharmaceutically acceptable salts and in vivo hydrolysable ester thereof; processes for their preparation; pharmaceutical compositions containing them and their use as antibacterial agents.
这项发明涉及式(I)的化合物,其中,例如,R1为式—NHC(═O)Ra,其中Ra为(1-4C)烷基;R2和R3分别为氢或氟;R5和R6为,例如,氢;R4为—X—Y—Het.;其中,例如,X为直接键,Y为—(CH2)m—或—CONH—(CH2)m—;或者X为—(CH2)n—,Y为—S(O)p—(CH2)m—;或者X为—CH2O—或—CH2NH—,Y为—CO—(CH2)m—;其中n为1、2或3;m为0、1、2或3,p为0、1或2;其中Het.为杂环,不饱和或饱和,可选择地被,例如,(1-4C)烷基、卤、氰基、硝基或氨基取代;其药学上可接受的盐及体内可水解的酯;其制备方法;含有它们的药物组合物及其作为抗菌剂的用途。
