of Lipinski demonstrated that all investigated compounds obeyed the rule of five. To further understand their geometry and electronic structure, DFT calculations with B3LYP method using 6-311++G(d,p) basic set were performed. In this context, the UV–Vis spectra of the investigated compounds were analyzed in detail, whereby the predicted absorption spectra from DFT calculation matched the experimentally
摘要 合成了两个系列的环烷螺-5-乙内酰脲,即环己烷螺-5-乙内酰脲和环庚烷螺-5-乙内酰脲在N3位具有4-取代的苄基或2-(4-取代的苯基)-2-氧乙基,并测试了它们对人结肠 (HCT-116)、白血病 (K562) 和乳腺癌 (MDA-MB-231) 癌细胞系增殖的影响。为了进行比较,我们还描述了 5,5-二苯基乙内酰脲类似物。所研究化合物的结构特征通过元素分析、FT-IR、UV-Vis、1H 和 13C NMR 光谱和 X 射线晶体学进行表征。关于它们的结构-活性关系,表明苄基部分被甲氧基、氯或溴基团取代增强了相对于母体化合物的抗增殖活性,而环烷基大小的增加主要导致抗增殖活性的降低。单晶X射线分析显示存在由NH⋯O氢键形成的二聚体和链。Lipinski 的分子描述符分析表明,所有研究的化合物都遵循五法则。为了进一步了解它们的几何形状和电子结构,使用 B3LYP 方法使用 6-311++G(d
