responsible for the antitumour activity of the compounds under investigation. The release of MeSeH from the active BSeCs has been confirmed by means of Head Space Gas Chromatography Mass Spectrometry techniques. The data that support this connection include the topography of the molecules, the conformational behaviour of the compounds, which influences the accessibility of the hydrolysis point, the interaction
已经对先前报道的一系列对称取代的双酰基酰亚胺硒代氨基甲酸酯(BSeC)衍生物进行了分子建模研究,该衍生物在体外显示出显着的抗肿瘤活性针对一组人类肿瘤细胞系。这些衍生物可被认为是围绕氨基甲酰亚氨脂酸甲酯核构建的中心支架,其中两个杂芳基酰基片段位于支架的氮原子上,从而形成不同的BSeC。结果表明,所选杂芳基环的性质对化合物的抗增殖活性具有显着影响,并且作为第一近似值,这与释放甲基硒醇(MeSeH)的能力有关。最初的假设最终决定了所研究化合物的抗肿瘤活性。MeSeH从活性BSeC中的释放已通过顶空气相色谱质谱技术确认。
