5-disubstituted derivatives all showed high activity when administered ip against ip-implanted P-388, but activity varied widely when the compounds were given orally. 4-Methoxy and 4-carbamoyl derivatives proved essentially inactive, whereas 4-methyl and 4-methylcarbamoyl derivatives retained activity. Exceptional oral activity was shown by the 4-methyl-5-methylcarbamoyl derivative, making this amsacrine
DNA嵌入剂amsacrine是治疗人类白血病和淋巴瘤的有效药物,但实体瘤活性极低。作为鉴定具有更广谱活性的类似物的第一步,对通过口服(po)和腹膜内(ip)途径给予的Amsacrine类似物的体内抗白血病(P-388)活性进行了比较。一系列的4-取代和4,5-二取代的衍生物在ip注射时对ip植入的P-388均显示出高活性,但是当口服给予化合物时,活性变化很大。事实证明4-甲氧基和4-氨基甲酰基衍生物基本上没有活性,而4-甲基和4-甲基氨基甲酰基衍生物保持活性。4-甲基-5-甲基氨基甲酰基衍生物显示出非凡的口服活性,使该氨溴萘衍生物值得进一步测试。
