  Synthesis and catalytic activities of PdII–phosphine complexes modified poly(ether imine) dendrimers

  摘要：

  In this paper, we report synthesis of new alkyldiphenyl phosphine ligand modified poly(ether imine) dendrimers up to the third generation. The phosphinated dendrimers were obtained by functional group transformations of the alcohols present at the periphery of the dendrimers to chloride, followed by phosphination using LiPPh2. The modification at the peripheries of the dendrimers was performed successfully to obtain up to 16 alkyl diphenylphosphines in the case of a third generation dendrimer, in good yields for each individual step. After phosphination, dendritic ligands were complexed with Pd(COD)Cl-2 to give dendritic phosphine-Pd-11 complexes. Both the ligands and the metal complexes were characterized by spectroscopic and spectrometric techniques including high-resolution mass spectral analysis for the lower generations. Evaluation of the catalytic efficacies of the dendrimer-Pd-11 metal complexes in mediating a prototypical C-C bond forming reaction, namely the Heck reaction, was performed using various olefin substrates. While the substrate conversion lowered with catalyst in the order from monomer to third generation dendrimer, the second and third generation dendrimers themselves were found to exhibit significantly better catalytic activities than the monomer and the first generation dendrimer.

  Poly propyl ether imine (PETIM) dendrimer: A novel non-toxic dendrimer for sustained drug delivery

  摘要：

  In the present study, an attempt was made to study the acute and sub-acute toxicity profile of G3-COOH Poly (propyl ether imine) [PETIM] dendrimer and its use as a carrier for sustained delivery of model drug ketoprofen. Drug-dendrimer complex was prepared and characterized by FTIR, solubility and in vitro drug release study. PETIM dendrimer was found to have significantly less toxicity in A541 cells compared to Poly amido amine (PAMAM) dendrimer. Further, acute and 28 days sub-acute toxicity measurement in mice showed no mortality, hematological, biochemical or histopathological changes up to 80 mg/kg dose of PETIM dendrimer. The results of study demonstrated that G3-COOH PETIM dendrimer can be used as a safe and efficient vehicle for sustained drug delivery. (C) 2010 Elsevier Masson SAS. All rights reserved.

  In this paper, we report the synthesis of several poly(propyl ether imine) dendrons and dendrimers. These dendrons and dendrimers were constructed by involving an ether as the linker component and an imine as the branching component. The divergent syntheses of dendrons and dendrimers were established with the aid of two alternate Michael addition reactions and two alternate reduction reactions in a

  在本文中，我们报告了几种聚（丙醚亚胺）树枝状和树枝状聚合物的合成。这些树枝状和树枝状大分子是通过包含醚作为连接剂组分和亚胺作为支化组分而构建的。借助两个交替的迈克尔加成反应和两个交替的还原反应以四步迭代的合成顺序建立树枝状和树枝状大分子的不同合成。合成了多达三代的树枝状分子，并将某些树枝状分子连接到类苯环核上，从而获得了多达两代的树枝状聚合物，其树枝状聚合物在外围含有12个羧酸。发现以醚为核心的发散合成更容易，在每个单独的步骤中，均获得了良好的收率和优异的收率，并且获得了在外围具有多达16个羧酸的三代树枝状大分子。采用的合成顺序使我们可以在其外围安装醇，胺或羧酸。对羧酸封端的树枝状和树枝状大分子的细胞毒性进行了评估，尽管大多数树枝状和树枝状大分子都没有表现出可测量的细胞毒性，甚至高达100微克/毫升，具有苯并类核的第二代树枝状大分子也显示出轻度的毒性。浓度超过30微克/毫升。

  as many as 11 catalysts within three generations were synthesized. The CC bond-forming reactions, namely, the Heck and the Suzuki coupling reactions, were then selected to study the catalytic efficiencies of the series of partially and fully phosphine-metal complex functionalized dendrimers. The efficacies of the formation of cinnamate and biphenyl, catalyzed by the dendritic catalysts, were compared

  迄今为止，在有关树状聚合物介导的催化作用的研究报告中，主要研究了催化单元的效率，并比较了各个世代。为了确定单个催化单元相对于给定世代中存在的此类单元的数量的功效，在一代内制备了一系列催化剂。选择与膦金属配合物结合的树枝状聚合物进行研究，并在三代内合成了多达11种催化剂。然后选择CC键形成反应，即Heck和Suzuki偶联反应，以研究一系列部分和完全膦-金属配合物官能化的树枝状聚合物的催化效率。比较了树状催化剂催化肉桂酸酯和联苯形成的效率。比较分析表明，当以多个数量存在时（即在多价树状体系中），单个催化位点的催化活性要比在同一世代（即在一价树状系统中）中的单个单元有效得多。这项研究确定了在树状聚合物世代之内和之间以及树状聚合物世代中催化部分多价呈递的有益作用。
• Covalent assembly-disassembly of poly(ether imine) dendritic macromolecular monomers and megamers

  Poly(ether imine) dendritic macromolecules were undertaken to study the reversible dendrimer monomer-megamer assembly-disassembly in aqueous solutions. Synthesis of thiol functionalized poly(ether imine) (PETIM) dendrimers and their covalent aggregation behavior in the aqueous solution of ethanol/water (2:1) is demonstrated. The dendritic megamers were characterized using microscopic techniques. Kinetics of the aggregation behavior was followed using turbidity measurements, light-scattering and atomic force microscopic techniques. Inherent luminescence behavior of PETIM dendrimer monomers was retained in the dendrimer megamers also, which allowed visualization of the megamers through confocal microscopy. Extent of thiol functionalities that remained after the megamer assembly was estimated through Ellman's assay. Subsequent to megamer assembly, disassembly of megamers to dendrimer monomers was conducted, using dithiothreitol reagent. Water-insoluble sudan I dye was encapsulated in dendrimer megamer and subsequent release profile was assessed during the disassembly in aqueous solutions. The studies were conducted using first, second and third generations, representing 4, 8 and 16 sulfhydryl groups at their peripheries of dendrimers, respectively. (C) 2014 Elsevier Ltd.
