The invention addresses radioresistance in cancer treatment involving radiotherapy and, in particular, limitations associated with the use of the drug sulfasalazine. Specifically, it provides a series of compounds for use as radiosensitizers in the treatment of cancers such as glioblastomas which are lethal and inherently resistant to radiotherapy, in one embodiment, the invention provides compounds of general formula (I), their stereoisomers and pharmaceutically acceptable salts for use as radiosensitizers in the treatment of cancer wherein ring A is selected from optionally substituted phenyl, biphenyl and fluorenyl; each X is independently selected from: -C1-6 alkyl (preferably C1-3 alkyl, e.g. -CH3), -O-C1-6 alkyl (preferably -O-C1-3 alkyl, e.g, -OCH3), -S-C1-6 alkyl (preferably -S-C1-3 alkyl, e.g, -SCH3), -OH, -SH, -CO2R1 (where R1 is H or C1-6 alkyl, preferably C1-3 alkyl, e.g. -CH3), -SO2-C1-6 alkyl (preferably -SO2-C1-3 alkyl, e.g. -SO2-CH3), -SO2-NR2R3 (where R2 is H and R3 is optionally substituted phenyl), -NR4R5 (wherein R4 and R5 are independently selected from H, C1-6 alkyl (preferably C1-3 alkyl, e.g. -CH3), and -CO-C1-6 alkyl (preferably -CO-C1-3 alkyl, e.g. -CO-CH3), halogen (e.g. F, Cl or Br), and optionally substituted tetrazolyl; n is an integer from 0 to 5, preferably 0 to 2, e.g. 1 or 2; and denotes an E or Z double bond.
该发明解决了涉及放射治疗的癌症治疗中的放射抗性问题,特别是与药物磺胺嘧啶的使用相关的限制。具体而言,它提供了一系列化合物,用作放射增敏剂治疗癌症,例如致命且固有对放射治疗具有抗性的胶质母细胞瘤。在一个实施例中,该发明提供了一般式(I)的化合物,它们的立体异构体和药学上可接受的盐,用作放射增敏剂治疗癌症,其中环A选自可选择取代的苯基、联苯基和芴基;每个X独立选自:-C1-6烷基(优选C1-3烷基,例如-CH3)、-O-C1-6烷基(优选-O-C1-3烷基,例如-OCH3)、-S-C1-6烷基(优选-S-C1-3烷基,例如-SCH3)、-OH、-SH、-CO2R1(其中R1为H或C1-6烷基,优选C1-3烷基,例如-CH3)、-SO2-C1-6烷基(优选-SO2-C1-3烷基,例如-SO2-CH3)、-SO2-NR2R3(其中R2为H且R3为可选择取代的苯基)、-NR4R5(其中R4和R5独立选自H、C1-6烷基(优选C1-3烷基,例如-CH3)和-CO-C1-6烷基(优选-CO-C1-3烷基,例如-CO-CH3)、卤素(例如F、Cl或Br)和可选择取代的四唑基;n为0到5的整数,优选为0到2,例如1或2;并表示E或Z双键。
