two-photon fluorescent imaging and anticancer purpose. The organotin (IV) complex (BuSnO)6L6 possessed strong one-photon exited fluorescence (1PF) intensity and moderate two-photon absorption cross-section in the near infrared region. Living cell evaluation revealed that (BuSnO)6L6 exhibited good bio-compatibility and outstanding selectivity in the selected tumor cell lines as well as in the normal cells
为双光子荧光成像和抗癌目的合理设计了两种新型有机锡羧酸盐配合物(BuSnO)6 L 6和Bu 3 SnOL,其中L =包含聚醚链的肉桂酸单元。有机锡(IV)络合物(BuSnO)6 L 6在近红外区具有很强的单光子出射荧光(1PF)强度和中等的两光子吸收截面。活细胞评估表明(BuSnO)6 L 6在选定的肿瘤细胞系以及正常细胞中均表现出良好的生物相容性和出色的选择性。此外,已经系统地研究了(BuSnO)6 L 6的抗肿瘤活性及其机理。结果表明(BuSnO)6 L 6可通过线粒体功能障碍,ROS(代谢过程中细胞产生的活性氧)和细胞色素c升高途径诱导凋亡细胞死亡。这项工作为合理设计具有双光子活性和抗肿瘤活性的羧酸盐有机锡复合物提供了新的策略。
