Photodynamic therapy (PDT) employing exogenous photosensitizers is currently being approved for treatment of basal cell carcinoma (BCC). 2-(4-Aminophenyl)benzothiazoles (6) consist of chromophoric structure and absorb light in the UVA (315–400 nm). These results encouraged us to design and synthesize a diversity of 2-phenylbenzothiazoles (6). Studies on the apoptotic mechanism involved in photosensitive effects
使用外源光敏剂的光动力疗法(PDT)目前已被批准用于治疗基底细胞癌(BCC)。2-(4-氨基苯基)苯并噻唑(6)由发色结构组成,可吸收UVA(315-400 nm)中的光。这些结果鼓励我们设计和合成各种2-苯基苯并噻唑(6)。在本文中研究了UVC激活的6在BCC细胞中诱导的光敏效应所涉及的凋亡机制。用6 -UVA处理的细胞显示出一些凋亡特征,包括亚G1群体的增加,膜联蛋白V结合的显着增加以及caspase-3的激活。6-UVA诱导线粒体膜电位(Δ降低ψ公吨),并通过增强的ROS产生和胞外信号调节激酶(ERK)和p38 MAPK表达的促进磷酸ATP。这些结果表明6- UVA在涉及ERK和p38活化的线粒体过程中引起光敏作用,并最终导致BCC细胞凋亡。
