Abstract: Three cw-combretastatin analogs (8 10) and three novel 1,2,3-triazole derivatives (5 7) have been synthesized. The ci'j-combretastatins were prepared from selective hydrogenation of the corresponding alkyne. Reaction of the alkyne intermediates with benzyl azide via the [3+2] dipolar cycloaddition provided the 1,2,3-triazoles compounds. Removal of the benzyl group by catalytic hydrogenation
摘要:已经合成了三种 cw-combretastatin 类似物 (8 10) 和三种新型 1,2,3-三唑衍生物 (5 7)。ci'j-combretastatins 由相应炔烃的选择性氢化制备。炔中间体与苄基叠氮化物通过 [3+2] 偶极环加成反应得到 1,2,3-三唑化合物。通过催化氢化除去苄基以良好的产率得到所需的三唑5 7 。使用基于 MTT 的测定法确定目标化合物对鼠 B16 黑色素瘤细胞生长的细胞毒性。结果证明三唑类具有与ci's-combretastatins相当的细胞毒性,化合物7和10的IC50值分别为56μM和55μM。
