摘要:

金属卤化物钙钛矿由于其多维度的晶体结构和优良的荧光成像/示踪及光电转换性质,使其成为一种非常具有前瞻性的光电增效治疗肿瘤材料。然而,传统卤化物钙钛矿纳米晶的水稳定性问题,限制了其应用于生物成像和光电增效肿瘤治疗的药物递送纳米系统研究。本文将甲氨蝶呤-壳聚糖-叶酸(MTX-CS-FA)成功与钙钛矿纳米晶体CsSn0.5Pb0.5Br3 (PeNCs)铆钉连接,制备出了可以在水中稳定228 d且发绿光的PeNCs@MTX-CS-FA纳米载药体系。在可见光照射下,新型PeNCs@MTX-CS-FA纳米载药体系增效抗肿瘤治疗原理:钙钛矿纳米晶体产生电子和活性氧(ROS);钙钛矿光生空穴耗竭过表达的谷胱甘肽(GSH);甲氨蝶呤(MTX)抑制二氢叶酸还原酶(DHFR)活性,导致肿瘤细胞的脂质过氧化,上述三点共同作用抑制肿瘤细胞的增殖、促进肿瘤细胞凋亡。在动物体内实验中,采用小鼠移植肿瘤模型,累积用药量达2.4 mg PeNCs@MTX-CS-FA纳米载药系统时,肿瘤体积减少了约63.68%和肿瘤重量下降了约63.26%。通过生物安全性评估实验证实,在治疗剂量下,小鼠肝、肾等器官功能正常,说明纳米体系具有良好的生物安全性,并且研究发现钙钛矿纳米颗粒经小鼠肠道排出,小鼠粪便呈现出与原始钙钛矿晶体相同的绿色荧光,金属卤化物钙钛矿纳米载药体系在生物成像和光电催化化疗方面呈现优异的增效抗肿瘤治疗效果。

Abstract:

Metal halide perovskites have emerged as highly promising materials in optoelectronics, owing to their unique multidimensional crystal structures that impart exceptional optical and electronic properties. These materials exhibit remarkable fluorescence imaging and tracking capabilities, as well as efficient photoelectric conversion, making them suitable for a broad range of applications. Nevertheless, despite their significant potential, their poor water stability has posed a major challenge, particularly in biomedical fields such as drug delivery systems, biological imaging, and photoelectrocatalytic oncotherapy. This limitation has hindered their practical use in medical treatments and diagnostics. In this study, we address the water stability issue by successfully synthesizing CsSn0.5Pb0.5Br3 perovskite nanocrystals (PeNCs) and conjugating them with methotrexate-chitosan-folic acid (MTX-CS-FA), resulting in innovative green light-emitting PeNCs@MTX-CS-FA nanoparticles. These nanoparticles exhibited remarkable water stability, maintaining their structural and functional integrity for up to 228 d, a significant improvement that enables their application in complex biological environments. Under visible light illumination, the nanoparticles demonstrated a dual-action therapeutic mechanism. The perovskites effectively generated electrons and reactive oxygen species (ROS), inducing oxidative stress in tumor cells. At the same time, photogenerated holes oxidized glutathione (GSH), a molecule that is typically overexpressed in tumor cells to protect against oxidative damage. By depleting GSH, the nanoparticles weakened the tumor cells' efense mechanisms, thereby enhancing the oxidative damage caused by ROS. In addition, methotrexate (MTX), a chemotherapeutic agent integrated into the system, inhibited dihydrofolate reductase (DHFR) activity. This inhibition disrupted tumor cell metabolism, particularly nucleotide synthesis, leading to lipid peroxidation and subsequent cell death. Together, these mechanisms generated a potent, synergistic therapeutic effect. The therapeutic efficacy of the PeNCs@MTX-CS-FA nanoparticles was validated through in vivo antitumor experiments in mice. A total dose of 2.4 mg of nanoparticles resulted in a 63.68% reduction in tumor volume and a 63.26% decrease in tumor weight, demonstrating significant tumor growth suppression. Biological safety evaluations further confirmed the nanoparticles' biocompatibility. Notably, they were excreted from the mice in their fluorescent form without decomposition, ensuring minimal long-term toxicity. This safe excretion pathway underscores the feasibility of repeated use of these nanoparticles in clinical applications. Overall, this study highlights the transformative potential of metal halide perovskites in cancer treatment. By overcoming the water stability limitations that have previously constrained their biomedical applications, the PeNCs@MTX-CS-FA nanoparticles exhibited outstanding capabilities in real-time bioimaging and effective photoelectrocatalytic chemotherapy, thus paving the way for future innovations in biomedical science.
