Benzo[de]isoquinoline-1,3-dione of Formula
or a pharmaceutically acceptable salt thereof wherein R is hydrogen or a protecting group typically used in the art for protecting alcohols and R1-R5 are each independently chosen from H, Cl, Br, F, straight or branched alkyl C1-C8 alkyl, C3-C8 cycloalkyl, heterocycle or bridged heterocycle of 4-9 atoms containing 1-3 heteroatoms, —(CR′2)nOR6, —(CR′2)nN(R6)2, —(CR′2)nNR6COR7, —(CR′2)nNR6SO2OR7, —(CR′2)nNR6SO2 N(R6)2, —(CR′2)nOSO2 N(R6)2, —(CR′2)nCN, —(CR′2)n(NOR6)R7, NO2, CF3, —(CR′2)nSOmR7, —(CR′2)nSOmR7, —(CR′2)nCO2R6, —(CR′2)nCON(R6)2, Ph, and any two of R1-R5 may form a substituted or unsubstituted ring of 5-7 total atoms having 0-2 heteroatoms are claimed which are selective inhibitors of bacterial DNA gyrase and DNA topoisomerase useful in antibacterial agents. Methods for their preparation and formulation as well as novel intermediates useful in the preparation of the final products are also claimed.
本专利申请涉及一种化合物Benzo[de] isoquinoline-1,3-dione或其药学上可接受的盐,其中R为氢或通常用于保护醇类的保护基,而R1-R5各自独立地选择从H、Cl、Br、F、直链或支链烷基C1-C8烷基、C3-C8环烷基、含有1-3个杂原子的4-9个原子的杂环或桥接的杂环,以及—(CR'2)nOR6、—(CR'2)nN(R6)2、—(CR'2)nNR6COR7、—(CR'2)nNR6SO2OR7、—(CR'2)nNR6SO2N(R6)2、—(CR'2)nOSO2N(R6)2、—(CR'2)nCN、—(CR'2)n(NOR6)R7、NO2、CF3、—(CR'2)nSOmR7、—(CR'2)nCO2R6、—(CR'2)nCON(R6)2、Ph。其中R1-R5中的任意两个可以形成5-7个总原子数的取代或未取代环,其中有0-2个杂原子。这些化合物是选择性抑制细菌DNA旋转酶和DNA拓扑异构酶的抗菌药物。本专利还涉及其制备方法和配方,以及用于制备最终产品的新中间体。
