adverse effects, three types of aromatic imide and diimides were designed to couple with different polyamines. The in vitro assays revealed that two naphthalene diimide–polyamine conjugates could inhibit the growth of multiple cancer cell lines more potently than amonafide. 9f, the most potent compound, was verified to efficiently induce apoptosis via a ROS mediated mitochondrial pathway in a preliminary
为了上调抗肿瘤功效和下调不良反应,设计了三种类型的芳族酰亚胺和二酰亚胺与不同的多胺偶联。体外测定显示,两种萘二酰亚胺-多胺缀合物比阿莫那肽更能有效抑制多种癌细胞系的生长。初步的机理研究证明,最有效的化合物9f可通过ROS介导的线粒体途径有效诱导细胞凋亡。三种H22肿瘤移植模型的综合体内试验表明9f改善了抑制效果和寿命延长指标,降低了血液毒性,这是阿莫那肽的主要缺点之一。更重要的是,观察到预防肺癌转移的能力明显提高,这增加了9f作为有前途的先导化合物的价值。这项工作支持多胺的通用功能可能赋予母体药物一些有趣的生物学特性。
