The invention provides novel analogues of enacyloxin Ha and their pharmaceutically acceptable salts, metabolites, isomers (e.g. stereoisomers) and prodrugs. Such compounds are effective in the treatment of infections caused by Gram-negative bacteria such as Acinetobacter baumannii. Compounds in accordance with the invention include those of formula (A), and their pharmaceutically acceptable salts, metabolites, isomers (e.g. stereoisomers) and prodrugs: In formula (A): X is 0 or NRx (where R* is either H or C1-3 alkyl, e.g. CH3); R1 is a 5- or 6-membered, saturated or unsaturated, carbocyclic ring optionally substituted by one or more substituents, or R1 is an optionally substituted straight-chained or branched C-1-6 alkyl group (e.g. C1-3 alkyl group); R2 is H, F, CI, Br, I or CH3; R3 is H or OH; R8 is a straight-chained or branched C1-8 alkyl group (e.g. a C1-6 aikyl group); Y is one of the following groups: (wherein each * denotes the point of attachment of the group to the remainder of the molecule; R9 is H, F, CI, Br or I; R4 and R5 are independently selected from H and OH, or R4 and R5 together are =0, preferably R4 is H and R5 is OH; R6 is H, F, CI, Br, I or CH3; R7 is H and R7' is OH, or R7 and R7' together are =0, preferably R7 is H and R7' is OH); and each— independently represents an optional bond (i.e. each of C2-C3, C4-C5, C6-C7, C8-C9 and C10-C11 are independently either C-C (single) or C=C (double) bonds).
这项发明提供了恩氨环素Ha的新型类似物及其药学上可接受的盐、代谢物、同分异构体(例如立体异构体)和前药。这些化合物在治疗由革兰氏阴性细菌引起的感染方面具有有效性,如包括鲍曼不动杆菌在内。符合该发明的化合物包括式(A)的化合物及其药学上可接受的盐、代谢物、同分异构体(例如立体异构体)和前药:在式(A)中:X为0或NRx(其中R*为H或C1-3烷基,例如CH3);R1为一个5-或6-成员的、饱和或不饱和的、碳环,可选择地由一个或多个取代基取代,或R1为一个可选择地取代的直链或支链C-1-6烷基基团(例如C1-3烷基基团);R2为H、F、Cl、Br、I或CH3;R3为H或OH;R8为一个直链或支链C1-8烷基基团(例如C1-6烷基基团);Y为以下各组中的一个:(其中每个*表示该组与分子其余部分的连接点;R9为H、F、Cl、Br或I;R4和R5分别独立选择自H和OH,或R4和R5一起为=0,优选R4为H且R5为OH;R6为H、F、Cl、Br、I或CH3;R7为H且R7'为OH,或R7和R7'一起为=0,优选R7为H且R7'为OH);每个—独立表示一个可选键(即C2-C3、C4-C5、C6-C7、C8-C9和C10-C11中的每一个独立地是C-C(单)或C=C(双)键)。
