The invention provides nitroaniline derivatives represented by general formula (I) where the nitro group is substituted at any one of the available benzene positions 2-6; where R and A separately represent the groups NO.sub.2, CN, COOR.sup.1, CONR.sup.1 R.sup.2, CSNR.sup.1 R.sup.2 or SO.sub.2 NR.sup.1 R.sup.2 and A is substituted at any one of the available benzene positions 2-6; where B represents N(CH.sub.2 CH.sub.2 halogen).sub.2 or N(CH.sub.2 CH.sub.2 OSO.sub.2 R.sup.3).sub.2 substituted at any one of the available benzene positions; and where R.sup.1, R.sup.2 and R.sup.3 separately represent H, or lower alkyl optionally substituted with hydroxyl, ether, carboxy or amino functions, including cyclic structures, or R.sup.1 and R.sup.2 together with the nitrogen form a heterocyclic structure, and pharmaceutical preparations containing them. These compounds have activity as hypoxia-selective cytotoxins, reductively-activated prodrugs for cytotoxins, hypoxic cell radiosensitisers, and anticancer agents.
本发明提供了一种由通式(I)表示的硝基苯胺衍生物,其中硝基基团取代在任何一个可用的苯环位置2-6;其中R和A分别表示NO.sub.2,CN,COOR.sup.1,CONR.sup.1 R.sup.2,CSNR.sup.1 R.sup.2或SO.sub.2 NR.sup.1 R.sup.2基团,并且A取代在任何一个可用的苯环位置2-6;其中B表示N(CH.sub.2 CH.sub.2卤素).sub.2或N(CH.sub.2 CH.sub.2 OSO.sub.2 R.sup.3).sub.2取代在任何一个可用的苯环位置;而R.sup.1,R.sup.2和R.sup.3分别表示H,或者低碳基,可选地取代羟基,醚基,羧基或氨基功能,包括环状结构,或者R.sup.1和R.sup.2与氮一起形成杂环结构,并且其中包含它们的制药制剂。这些化合物具有作为低氧选择性细胞毒素,还原激活的细胞毒素前药,低氧细胞放射增敏剂和抗癌剂的活性。
