nitrogen isosters of the angular furocoumarin angelicin, with the aim of obtaining new photochemotherapeutic agents with increased antiproliferative activity and lower undesired toxic effects. A versatile synthetic pathway was approached to allow the isolation of derivatives of the new ring system with a good substitution pattern on the pyrrole moiety. Photobiological screenings of the new compounds
合成吡咯并[3,4- h ]喹啉-2-酮作为角呋喃香豆素当归的氮等价物,目的是获得具有增加的抗增殖活性和较低的不良毒性作用的新型光化学治疗剂。寻求一种通用的合成途径以分离具有在吡咯部分上的良好取代模式的新环系统的衍生物。新化合物的光生物学筛选显示出强大的光毒性作用和很大的UVA剂量依赖性,在亚微摩尔水平下达到IC 50值。诱导的细胞光细胞毒性与线粒体和溶酶体的参与,细胞周期谱的改变和膜脂质过氧化的凋亡有关。
