Various methoxy- and hydroxy-substituted dibenz[c,e]oxepines were prepared via the copper(I)-induced coupling of ether-tethered arylstannanes or the dehydrative cyclisation of 1,1′-biphenyl-2,2′-dimethanols, assembled using the Ullmann cross-coupling of ortho-bromoaryl carbonyl compounds. The dibenzoxepines were screened for their ability to inhibit tubulin polymerisation and the in vitrogrowth of
通过铜(I)诱导的醚基芳基锡烷基醚的偶联或1,1'-联苯-2,2'-二甲醇的脱水环化反应制备了各种甲氧基和羟基取代的二苯并[ c,e ]氧杂环平使用邻-溴芳基羰基化合物的乌尔曼交叉偶联。筛选了二苯并xepines抑制微管蛋白聚合的能力以及K562人慢性骨髓性白血病细胞的体外生长。最活跃的是5,7-二氢-3,9,10,11-四甲氧基二苯并[ c,e ] oxepin -4-ol,其微管蛋白抑制作用和细胞毒性(IC 50)值分别为1μM和40 nM。
