The invention relates to pyrrolobenzodiazepines compounds (PBDs) and to pharmaceutically acceptable salts thereof, which are useful as medicaments, in particular, to treat bacterial infections. The PBDs are compounds of formula (I): and salts and solvates thereof; wherein: dotted lines indicates the optional presence of a double bond; X, X1, X2, X3 and X4 are connecting functional groups; L is C1-12 alkylene; R4, R5 and R6 are independently selected from phenylene, cyclopentanylene, cyclohexanylene, 5- to 9-membered heteroarylene and 5- to 6-membered hetereocyclylene groups, and these groups are optionally substituted with up to three optional substituent groups; R7 is selected from N(C1-6 alkyl)(C1-6alkyl), 5- to 6-membered nitrogen-containing hetereocyclyl groups, a monosaccharide moiety and an amino monosaccharide moiety wherein these groups are optionally substituted; and R8 and R9 either together form a double bond, or are selected from H and OR14, or R8 is a prodrug moiety and R9 is OR14; m is 0 or 1; with the proviso that when X4 is C(O)NH then the up to three optional substituents of R7 are not selected from (CH2)k-CO2R12; with the proviso that when X4 is (CH2)tO then R4 is not phenylene, m is 1 and R6 is not a 5- to 9-membered heteroarylene; and with the proviso that when X4 is C(O)NH or NHC(O) that R4 and/or R6 is not 5- to 9-membered heteroarylene.
本发明涉及吡咯并二氮杂卓化合物(PBDs)及其药学上可接受的盐类,它们可用作药物,特别是治疗细菌感染。PBDs 是式 (I) 的化合物:及其盐和溶解物;其中虚线表示任选存在双键;X、X1、X2、X3 和 X4 为连接官能团;L 为 C1-12 亚烷基;R4、R5 和 R6 独立选自亚苯基、环戊烯基、环己烯基、5-至 9 元杂芳基和 5-6 元对位环亚苯基,这些基团可任选被最多三个任选取代基取代;R7 选自 N(C1-6烷基)(C1-6烷基)、5 至 6 元含氮杂环烯基、单糖分子和氨基单糖分子,其中这些基团任选被取代;R8和R9或者一起形成双键,或者选自H和OR14,或者R8为原药分子,R9为OR14;m为0或1;但当X4为C(O)NH时,R7的最多三个任选取代基不选自(CH2)k-CO2R12;但当 X4 为 (CH2)tO 时,R4 不是亚苯基,m 为 1,R6 不是 5 至 9 元杂芳基;但当 X4 为 C(O)NH 或 NHC(O) 时,R4 和/或 R6 不是 5 至 9 元杂芳基。
