Hypoxia is a feature of several disease states, including cancer and rheumatoid arthritis. Prodrug systems which, after bioreduction, selectively release active drugs in these tissues may be important in therapy. An improved preparation of 1,2-dimethyl-3-hydroxymethyl-5-methoxyindole-4,7-dione was developed. Mitsunobu coupling with (5-substituted) isoquinolin-1-ones (potent inhibitors of poly(ADP-ribose)polymerase)
缺氧是几种疾病状态的特征,包括癌症和类风湿关节炎。经过生物还原后,在这些组织中选择性释放活性药物的前药系统在治疗中可能很重要。开发了一种改进的1,2-二甲基-3-羟甲基-5-甲氧基吲哚-4,7-二酮的制备方法。与(5-取代的)异喹啉-1-酮(聚(ADP-核糖)聚合酶的有效抑制剂)的光延结合产生1-(1,2-二甲基-4,7-二氧代-5-甲氧基吲哚-3-基甲氧基)异喹啉和ñ - (1,2-二甲基-4,7-二氧代-5-甲氧基吲-3-基甲基)异喹啉-1-酮。与抗癌药物五甲基三聚氰胺的类似偶联产生了其潜在的前药1,2-二甲基-3-(N-(4,6-双(二甲基氨基)-1,3,5-三嗪-2-基)-N-甲基氨基甲基)-5-甲氧基吲哚-4,7-二酮。用3-氯甲基-1,2-二甲基-5-甲氧基吲哚-4,7-二酮处理泼尼松龙半琥珀酸钠可得到抗炎药泼尼松龙的类似候选药物。在用于生物还原的化学模型系统中,CDCl 3 /
