enter clinical phase III, because of its high-variable and unpredictable toxicity. In order to develop selective, efficient, and safe drugs, applying the ‘nonfused’ aromatic system strategy, a series of 5-non-amino aromatic substituted naphthalimides as replacement for amonafide were designed and were synthesized from naphthalic anhydride by three steps including bromination, amination, and Pd(PPh3)4
阿莫那肽是一种具有抗肿瘤活性的萘二甲酰亚胺衍生物,由于其多变且不可预测的毒性而未能进入临床III期。为了开发选择性,高效和安全的药物,应用“非融合”芳族体系策略,设计了一系列5-非氨基芳族取代萘二甲酰亚胺替代阿莫那肽,并通过包括溴化在内的三个步骤从萘酐中合成了这些化合物:胺化反应和Pd(PPh 3)4催化的Suzuki反应。这些新的萘二甲酰亚胺衍生物,4b除外,不仅在相同的实验条件下在体外对HeLa和P388D1细胞系表现出比阿莫那肽更好的活性,而且由于其结构(在5位缺少易乙酰化的芳胺),还可以避免阿莫那肽的副作用。还研究了萘二甲酰亚胺衍生物的DNA结合行为,结果表明它们通过插层与DNA结合,而4a和4g以不同方式插层到DNA中。
