synthesis of the pyrano[2,3-e]isoindol-2-one ring system, an heteroanalogue of angelicin, is reported. Our synthetic approach consists of the annelation of the pyran ring on the isoindole moiety using 5-dialkylamino- or 5-hydroxymethylene intermediates as building blocks. The photoantiproliferative activity of the newderivatives was studied. Some of them bearing the benzyl group at the 8 position
据报道,吡喃并[2,3 - e ] isoindol-2-one环系统,即当归的杂类似物,可以方便地合成。我们的合成方法包括使用5-二烷基氨基-或5-羟基亚甲基中间体作为结构单元,使吡喃环在异吲哚部分上的成环反应。研究了新衍生物的光抗增殖活性。其中一些在8位带有苄基的化合物在微摩尔范围内具有IC 50活性。细胞的细胞毒性涉及细胞凋亡,细胞周期概况的改变和膜的光损伤。
