Three series of novel oxo-heterocyclic fused naphthalimide derivatives (8a–8f, 13a–13d, 17a–17d) were prepared. The newly-synthesized compounds, and their thio-heterocyclic fused analogs (1a–1c, 2a–2d, 3a–3c) exhibited potent antiproliferative activity correlated well with their structure. Further research demonstrated that all the representative compounds 13a, 2a and 17a, 3a showed strong inhibition
制备了三个系列的新颖的氧-杂环稠合的萘二甲酰亚胺衍生物(8a - 8f,13a - 13d,17a - 17d)。新合成的化合物及其硫杂环稠合的类似物(1a - 1c,2a - 2d,3a - 3c)显示出有效的抗增殖活性,与其结构密切相关。进一步的研究表明,所有代表性化合物13a,2a和17a,3a与阿莫那肽相似,它对topo II具有很强的抑制活性,并且对topo I的抑制作用也很强,以前很少报道过萘二甲酰亚胺衍生物。初步探索证明了他们的DNA序列偏好。总而言之,双重的topo I / topo II抑制作用和DNA序列优先选择可能有助于增强肿瘤的选择性并克服耐药性。
