In the search for new photochemotherapeutic agents, a series of derivatives of the ring system pyrrolo[3,2-h]quinoline—bioisosters of the angular furocoumarin angelicin—were synthesized through a four-step synthetic approach, in reasonable overall yields. Eight of the synthesized derivatives showed a remarkable phototoxicity against a panel of four human tumor cell lines and a great dose UV-A dependence
在寻找新的光化学治疗剂时,通过四步合成方法以合理的总收率合成了一系列环系统吡咯并[3,2 - h ]喹啉衍生物(角型呋喃香豆素当归的生物异构体)。八种合成衍生物对一组四个人类肿瘤细胞系表现出显着的光毒性,并具有大剂量的UV-A依赖性,在亚微摩尔水平下达到IC 50值。通过一系列的流式细胞仪分析评估了吡咯并[3,2- h ]喹啉光诱导的细胞死亡方式,并进行了其他测试以阐明其作用机理。
