A set of novel selenohydantoins were synthesized via a convenient and versatile approach involving the reaction of isoselenocyanates with various amines. We also revealed an unexpected Z→E isomerization of pyridin-2-yl-substituted selenohydantoins in the presence of Cu2+ cations. The detailed mechanism of this transformation was suggested on the basis of quantum-chemical calculations, and the key role
通过一种方便且通用的方法合成了一组新型硒代乙内酰脲,涉及异戊烯异氰酸酯与各种胺的反应。我们还揭示了在Cu 2+阳离子存在下,吡啶-2-基取代的硒代乙内酰脲发生意外的Z → E异构化。在量子化学计算的基础上,提出了这种转变的详细机理,并指出了Cu 2+的关键作用。被阐明。随后针对一组不同的癌细胞系评估获得的化合物。结果,几个分子被鉴定为具有良好选择性指数的有希望的微摩尔样品。代替以前已合成的类似硫代乙内酰脲,硒代乙内酰脲显示出相对较高的抗氧化活性,可与参考分子Ebselen(临床批准的候选药物)相比(或更高)。选择了活性最高的化合物用于进一步的生物学试验。
