摘要

在第二个近红外窗口（NIR-II）具有吸收功能的功能性染料在光热疗法中大有可为。本文制备了新型 NIR-II 3,5-julolidinyl aza-BODIPY (JLD)，并首次通过 X 射线晶体分析进行了确认。其分子堆积结构有利于 J 聚集堆积模式。自组装的JLD-纳米粒子（JLD-NPs）发出荧光（λem = 962 nm, Φf = 0.1%），峰带覆盖900-1300 nm的近红外-II波段。光热转换效率很高，经计算为 79%。JLD-NPs 在近红外-II波段915 nm激光照射下具有良好的肿瘤抑制能力，通过脑立体定向注射促进胶质母细胞瘤细胞凋亡和抑制干细胞，影响迁移和侵袭等恶性事件的发生。

Novel NIR-II 3,5-Julolidinyl aza-BODIPY for Photothermal Therapy of Gliomas Stem Cells by Brain Stereotactic Injection

Functional dyes with absorption in the second near-infrared window (NIR-II) show great promise in photothermal therapy. Herein, the novel NIR-II 3,5-julolidinyl aza-BODIPY (JLD) was prepared and confirmed by X-ray crystallographic analysis for the first time. The molecular packing structure facilitates the J-aggregation packing mode. Self-assembled JLD-nanoparticles (JLD-NPs) emit fluorescence (λ_em = 962 nm, Φ_f = 0.1%), and a peak belt covered a NIR-II range of 900–1300 nm. The photothermal conversion efficiency was high and was calculated to be 79%. JLD-NPs with NIR-II 915 nm laser irradiation had the good tumor-inhibition capability with promoting the apoptosis and inhibiting the stemness of glioblastoma cells by brain stereotactic injection and affect the occurrence of malignant events, such as migration and invasion.
