    Sub-picosecond photoinduced electron transfer in water-soluble porphyrin dimers
    摘要:
    Picosecond as well as femtosecond transient absorption measurements have been performed on eight water-soluble heterodimers consisting of combinations of oppositely charged free base and metal porphyrins which have been electrochemically characterized. The ultrafast non-exponential absorption increase, attributed to solvent-controlled, intradimer charge separation, is energy-gap independent. By contrast, the much slower charge recombination is energy-gap dependent.

    摘要:
    已经制备了包含锌(II),钯(II)或锡(IV)离子作为中心金属的水溶性抗磁性金属卟啉,并且已经在稀水溶液中测量了它们的光物理性质。所有化合物都经过有效的系统间交换,形成可以参与电子转移反应的长寿命激发三重态。因此,在含有合适的电子受体,例如铁(III)的稀水溶液中激发金属卟啉可导致以相当高的产率形成金属卟啉π-自由基阳离子。这些π-自由基阳离子是强氧化剂,在某些情况下为E °与NHE相比> 1 V ,但它们会发生次级反应,导致π指示剂和异卟啉的形成。尽管具有高的氧化还原电势,但是即使在氧化还原催化剂如RuO 2的存在下,也无法将π-自由基阳离子的单电子还原与水到分子氧的四电子氧化偶联。因此,这些化合物似乎在均相光系统中作为水氧化剂的前景不大。

  • Metalloporphyrin Pd(T4) Exhibits Oncolytic Activity and Cumulative Effects with 5-ALA Photodynamic Treatment against C918 Cells

    Photodynamic therapy is a non-invasive method where light activates a photosensitizer bound to cancer cells, generating reactive oxygen species and resulting in cell death. This study assessed the oncolytic potential of photodynamic therapy, comparing European Medicines Agency and United States Food and Drug Administration-approved 5-aminolevulinic acid (5-ALA) to a metalloporphyrin, Pd(T4), against a highly invasive uveal melanoma cell line (C918) in two- and three-dimensional models in vitro. Epithelial monolayer studies displayed strong oncolytic effects (>70%) when utilizing Pd(T4) at a fraction of the concentration, and reduced pre-illumination time compared to 5-ALA post-405 nm irradiance. When analyzed at sub-optimal concentrations, application of Pd(T4) and 5-ALA with 405 nm displayed cumulative effects. Lethality from Pd(T4)-photodynamic therapy was maintained within a three-dimensional model, including the more resilient vasculogenic mimicry-forming cells, though at lower rates. At high concentrations, modality of cell death exhibited necrosis partially dependent on reactive oxygen species. However, sub-optimal concentrations of photosensitizer exhibited an apoptotic protein expression profile characterized by increased Bax/Bcl-2 ratio and endoplasmic stress-related proteins, along with downregulation of apoptotic inhibitors CIAP-1 and -2. Together, our results indicate Pd(T4) as a strong photosensitizer alone and in combination with 5-ALA against C918 cells.

    光动力疗法是一种非侵入性方法,其中光激活结合在癌细胞上的光敏剂,产生活性氧自由基,导致细胞死亡。本研究评估了光动力疗法的肿瘤溶解潜力,比较了欧洲药品管理局和美国食品和药物管理局批准的5-氨基戊酸(5-ALA)和一种金属卟啉Pd(T4)对高侵袭性葡萄膜黑色素瘤细胞系(C918)在二维和三维模型中的作用。上皮细胞单层研究显示,在使用Pd(T4)的浓度分数和比5-ALA后405纳米辐照时间减少时,具有强烈的溶瘤效果(> 70%)。在亚优化浓度下分析时,应用Pd(T4)和5-ALA与405纳米显示累积效应。 Pd(T4)光动力疗法的致死率在三维模型中得以维持,包括更具弹性的生成血管模拟细胞,但速率较低。在高浓度下,细胞死亡方式表现为部分依赖于活性氧自由基的坏死。然而,光敏剂的亚优化浓度表现出一种凋亡蛋白表达谱,其特征是增加的Bax / Bcl-2比率和内质网应激相关蛋白,以及凋亡抑制剂CIAP-1和-2的下调。综上所述,我们的结果表明,Pd(T4)是一种强大的光敏剂,可单独和与5-ALA一起对抗C918细胞。
