    摘要:
    本发明提供了一种新型的卟啉衍生物,其通式为1,并/或其药用可接受的衍生物,作为近红外光敏剂,用于光动力治疗和诊断、生物和工业应用。这些卟啉衍生物在生物色素不吸收的区域具有吸收(400-700 nm)和发射(600-750 nm),因此是作为近红外光动力治疗剂和荧光传感器在生物学医学应用中的理想候选者。这些染料上的羟基和甘醇基等取代基使它们具有两性亲和性,从而提高了它们在水介质和细胞中的溶解度和摄取和定位。这些染料在暗中不显示毒性,并且对肿瘤细胞高度选择性,并且非常快速地染色细胞核。因此,这些卟啉衍生物在光动力治疗和诊断、生物和工业应用中作为近红外光动力治疗荧光传感器是非常有用的。

  • Effects of methoxy-substituted metalloporphyrins in catalytic alkene epoxidation by n-<font>Bu</font><sub>4</sub><font>NHSO</font><sub>5</sub>
    作者:Amineh Aghabali、Nasser Safari
    DOI:10.1142/s1088424610002136
    日期:2010.4

    TPPMnOAc and four different kinds of manganese tetraphenylporphyrin acetates were synthesized using different numbers of methoxy substituents in various positions of the phenyl rings. These porphyrins were used as catalysts in the epoxidation of various alkenes with tetra-n-butylammonium hydrogen monopersulfate (n- Bu 4 NHSO 5) as the oxidant and imidazole as the axial base. The following order of catalytic activity was obtained: TPPMnOAc ≥ T (2,3- OMeP ) PMnOAc > T (4- OMeP ) PMnOAc > T (3,4- OMeP ) PMnOAc > T (2,4,6- OMeP ) PMnOAc . By studying the UV-vis spectra in the reaction solution, the stability of the applied methoxy porphyrins and the effect of this factor on obtained yields were investigated. Lower catalytic activity in some of the methoxy porphyrins emphasized steric effects and special hydrogen bonding among the reaction elements. However, the stability of T (2,3- OMeP ) PMnOAc under our reaction condition was considerable and high activity was observed. By adding small amounts of alcohol to the reaction solution, the effect of the solvent mixture was previewed and steps were taken to identify the active intermediate of the catalyst in these conditions.

    利用苯环不同位置上不同数量的甲氧基取代基合成了 TPPMnOAc 和四种不同的四苯基卟啉醋酸。这些卟啉被用作催化剂,以四正丁基硫酸氢铵(n- Bu 4 NHSO 5)为氧化剂,咪唑为轴向碱,对各种烯烃进行环氧化反应。催化活性顺序如下TPPMnOAc ≥ T (2,3- OMeP ) PMnOAc > T (4- OMeP ) PMnOAc > T (3,4- OMeP ) PMnOAc > T (2,4,6- OMeP ) PMnOAc 。通过研究反应溶液中的紫外-可见光谱,研究了所应用的甲氧基卟啉的稳定性以及该因素对所得产率的影响。一些甲氧基卟啉的催化活性较低,强调了立体效应和反应元素之间特殊的氢键。然而,在我们的反应条件下,T (2,3- OMeP ) PMnOAc 具有很高的稳定性和活性。通过在反应溶液中加入少量的酒精,预览了混合溶剂的影响,并采取步骤确定了催化剂在这些条件下的活性中间体。
