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.
该发明涉及吡咯苯二氮杂环烷化合物(PBD)及其药用可接受盐,其作为药物具有治疗细菌感染的功效。PBD是具有以下结构式(I)的化合物:及其盐和溶剂化物;其中:虚线表示双键的可选存在;X、X1、X2、X3和X4是连接的功能基团;L为C1-12烷基;R4、R5和R6分别选自苯环、环戊烷基、环己烷基、5-至9-成员杂芳烃基和5-至6-成员杂环烷基,这些基团可选地被高达三个可选取代基团取代;R7选自N(C1-6烷基)(C1-6烷基)、5-至6-成员含氮杂环基团、单糖基团和氨基单糖基团,其中这些基团可选地被取代;R8和R9要么一起形成双键,要么选自H和OR14,或者R8是前药基团且R9是OR14;m为0或1;但是当X4为C(O)NH时,R7的高达三个可选取代基团不选自(CH2)k-CO2R12;但是当X4为(CH2)tO时,R4不是苯环,m为1且R6不是5-至9-成员杂芳烃基;但是当X4为C(O)NH或NHC(O)时,R4和/或R6不是5-至9-成员杂芳烃基。
