complex of the hexacationic Pc 6, which has been obtained as iodide salt through quaternization of the neutral precursor with methyl iodide. Compound 6 was synthesized over a sequence of four steps. The complex, and its precursors as well, were characterized by a combination of spectroscopic techniques, and their structures assessed by 1 H, 13 C, 11 B, and two-dimensional NMR spectroscopy experiments. Together
硼化的分子系统可以应用于硼中子俘获治疗(BNCT)。在这些系统中,含碳硼烷的酞菁(Pcs)是最有前途的BNCT试剂。本文中,我们报告了六阳离子Pc 6的新型锌(II)络合物,该络合物已通过中性前体与甲基碘的季铵化反应以碘盐的形式获得。化合物6是通过四个步骤的序列合成的。该复合物及其前体也通过结合光谱技术进行了表征,并通过1 H,13 C,11 B和二维NMR光谱实验对它们的结构进行了评估。连同明显的聚集趋势,6在水中显示出可观的溶解度。在DMF溶液中获得6的单重态氧量子产率(ΦΔ)为0.38,荧光量子产率(ΦF)为0.13。事实证明,该复合物在富集10 B的UMR-106细胞方面非常有效,即使在极低浓度的暴露(即i)下也显示出非常好的性能。e。1ppm,还导致轻微的细胞毒性作用。这样的特征可以与复合物的聚阳离子性质有关,并因此与带正电荷的物质进入细胞膜或粘附于其外表面的众所周知的倾向有关。
