their thiophene analogues, all non-charged derivatives and amidino-phenyl-substituted analogues didn't show acceptable photoconversion. The significantly stronger antiproliferative activity of cyclic analogues could be correlated to the property of these molecules to intercalate into DNA. The acyclic molecules did not show any interaction with DNA, correlating with the inferior biological activity, except
作为通过光诱导形成嵌入剂改善传统光动力疗法替代方法研究的一部分,我们合成了一系列新型杂环化合物及其无环前体。现在,我们就其光诱导环化的潜力,与DNA的相互作用以及体外对肿瘤细胞生长的抑制作用,报告其合成/表征的详细信息。在研究的化合物中,只有酰胺基-呋喃基取代的丙烯酸苯基酯可以有效地转化为相应的萘呋喃,而它们的噻吩类似物,所有不带电荷的衍生物和酰胺基-苯基取代的类似物均未显示出可接受的光转化。环状类似物明显更强的抗增殖活性可能与这些分子插入DNA中的特性有关。
