A new class of antitumor agents, having structural analogy to amonafide, but differing by the addition of a fourth ring in the nucleus, was synthesized conveniently from anthracene. Compounds with a variety of substituents, containing a basic nitrogen atom and located on the imide nitrogen, were prepared. Thirteen of 19 new compounds had greater growth inhibitory potency than amonafide in a panel of
从蒽中方便地合成了一类新的抗肿瘤药,其结构类似于阿莫那肽,但在核中增加了第四个环而有所不同。制备了具有多种取代基的化合物,这些取代基包含碱性氮原子并且位于酰亚胺氮上。使用磺基若丹明B和MTT染料分析,在一组培养的鼠和人肿瘤细胞中,19种新化合物中的13种具有比阿莫那利更大的生长抑制能力。活性最高的药物在体外对正常新生大鼠心肌的毒性比阿莫那利相似,但它们的化学治疗指数更高。从这些化合物中,选择了具有2-(二甲基氨基)乙基侧链的化合物(称为阿佐那非)以进行进一步研究。它对一组培养的人结肠癌细胞显示出高效力,并且对小鼠的ip P388白血病和皮下B16黑色素瘤具有活性。初步的结构活性相关性表明,侧链氮的碱性和侧链的长度是体外抗肿瘤潜能的重要决定因素。侧链的立体阻碍和刚性可能是其他决定因素。
