Structurally diverse bicyclo[3.3.0]octanes were prepared and tested for their biological activity. Both the antiproliferative activity and the results of phenotypic characterization varied with the substitution patterns. Two derivatives displayed high inhibitory (IC50 ⩽3 μM) activity against the L-929 cell line, but differed in their mode of action. A cluster analysis with impedance profiling data
制备了结构多样的双环[3.3.0]辛烷,并对其生物学活性进行了测试。抗增殖活性和表型表征的结果都随取代模式而变化。两种衍生物显示高抑制(IC 50靠在L-929细胞系⩽3μM)活性,但在它们的作用模式不同。带有阻抗谱数据的聚类分析表明,这两种化合物与微管干扰化合物有关。在用这两种衍生物处理的PtK 2细胞中,观察到对微管网络的干扰作用,而在培养的PtK 2中的肌动蛋白细胞骨架细胞仅受一种化合物干扰。通过体外聚合实验可以证实对微管蛋白和肌动蛋白聚合的影响。
