of arylidene derivatives of alicyclic ketones and some corresponding oximes, oxime esters, and related compounds were prepared as candidate cytotoxic agents. All of the compounds were evaluated against murine L1210 lymphoid leukemia cells. In general, cytotoxicity was greatest with the alpha,beta-unsaturated ketones and diminished with the oximes, and the oxime esters had little or no activity in this
制备了许多脂环族酮的亚芳基衍生物和一些相应的肟,肟酯和相关化合物作为候选细胞毒剂。所有化合物均针对鼠L1210淋巴样白血病细胞进行了评估。通常,α,β-不饱和酮的细胞毒性最大,而肟则减少,而肟酯在该筛选中几乎没有或没有活性。在体外L1210和P388白血病筛查中检查相同的化合物时,在大多数情况下,L1210细胞对这些衍生物更敏感。所制备的化合物的一半以上在体外针对约55种人类肿瘤进行了评估,并显示出对一组或多组肿瘤疾病(尤其是白血病)的选择性毒性。可以看出结构和生物活性之间的一些相关性。代表性化合物的细胞毒性筛选和稳定性研究表明,酮,肟和肟酯在生物评价条件下是稳定的。四种代表性化合物的X射线晶体学分析揭示了与细胞毒性相关的结构特征,可在设计未来候选细胞毒素时考虑这些特征。
