A new class of compounds, the thiopyrano[2,3-e]indol-2-ones, bioisosters of the angular furocoumarin angelicin, was synthesized with the aim of obtaining new photochemotherapeutic agents. In particular 7,8-dimethyl-thiopyranoindolone 6c s showed a remarkable phototoxicity and a great dose UVA dependence reaching IC(50) values at submicromolar level. This latter photoinduced a massive apoptosis and
为了获得新的光化学治疗剂,合成了一类新的化合物,即角呋喃香豆素当归的生物等位基因thiopyrano [2,3-e] indol-2-ones。特别是7,8-二甲基-硫代吡喃并吲哚酮6c s表现出了显着的光毒性,并且在亚微摩尔水平上对UVA的依赖性很大,达到了IC(50)值。后者光诱导大量的细胞凋亡,并对脂质和蛋白质产生显着的光损伤。尽管它不插入DNA,但它能够引起DNA碱基的光氧化。
