A dual‐functional photosensitizer that demonstrates exceptional photodynamic therapy (PDT) efficacy while simultaneously self‐monitoring the therapeutic response in real time is reported here. Possessing an ultrahigh 1O2 quantum yield of 98.6% in water, the photosensitizer TPCI can efficiently induce cell death in a series of carcinoma cells (IC50 values less than 300 × 10−9 m) upon irradiation with an extremely low fluence (460 nm, 4 mW cm−2 for 10 min). In addition, TPCI can self‐monitor cell death in real time. It is weakly fluorescent in living cells before irradiation and lights up the nuclei concomitantly with cell death during PDT treatment by binding with chromatin to activate its aggregation‐induced emission, attributed to its strong binding affinity with DNA. In vivo studies using mouse models bearing H22 and B16F10 tumor cells validate the ultraefficient PDT efficacy of TPCI as well as the precise real‐time noninvasive readout of the tumor response from the beginning of cancer treatment. The dual‐functional TPCI serves as an excellent candidate for single‐agent photodynamic theranostics, and this work represents a new paradigm for the development of molecules with multiple intrinsic functions for future self‐reporting medical applications.

用于高效光动力疗法和同步抗癌功效监测的双功能光敏剂
本文报道了一种双功能光敏剂,该光敏剂具有出色的光动力疗法(PDT)功效,同时可以实时自我监测治疗反应。光敏剂TPCI在水中具有98.6%的超高1 O 2量子产率,在以极低通量(460)照射后,可以有效诱导一系列癌细胞(IC 50值小于300×10 -9 m)的细胞死亡。纳米,4 mW cm -210分钟)。此外,TPCI可以实时自我监测细胞死亡。它在辐射前在活细胞中微弱地发出荧光,并在PDT处理期间通过与染色质结合以激活其聚集诱导的发射而点亮细胞核,这归因于其与DNA的强结合亲和力。使用荷有H22和B16F10肿瘤细胞的小鼠模型进行的体内研究验证了TPCI的超高效PDT功效以及从癌症治疗开始就精确实时地无创读取肿瘤反应。双重功能的TPCI是单剂光动力学治疗药物的极佳候选者,这项工作代表了开发具有多种内在功能的分子以用于未来的自我报告医学应用的新范例。
