Novel indolo[3,2-b]quinoline derivatives (1c--f), which carried a methoxy or a hydroxy group at the 4- or 7-position of the lead compound 1a, were prepared and their antitumor activities against P388 in mice were examined. Except for the 4-hydroxy derivative (1d), these showed remarkably potent activity. Among these compounds, the 7-hydroxy derivative (1f) was the most potent one (optimal dose = 50
制备了新的吲哚并[3,2-b]喹啉衍生物(1c-f),其在前导化合物1a的4位或7位带有甲氧基或羟基,并在小鼠中具有抗P388的抗肿瘤活性。被检查。除4-羟基衍生物(1d)外,它们均显示出显着的活性。在这些化合物中,7-羟基衍生物(1f)是最有效的化合物(最佳剂量= 50 mg / kg,治疗组/对照组的中位生存时间(T / C)大于330%,治愈= 5 / 6)。
