Discrete multiporphyrin pseudorotaxane assemblies from di- and tetravalent porphyrin building blocks

12-May-2015 | Mirko Lohse, Larissa K. S. von Krbek, Sebastian Radunz, Suresh Moorthy, Christoph A. Schalley and Stefan Hecht, Beilstein Journal of Organic Chemistry, 2015

Abstract Two pairs of divalent and tetravalent porphyrin building blocks carrying the complementary supramolecular crown ether/secondary ammonium ion binding motif have been synthesized and their derived pseudorotaxanes have been studied by a combination of NMR spectroscopy in solution and ESI ...

Glycodendrimers: tools to explore multivalent galectin-1 interactions

12-May-2015 | Jonathan M. Cousin and Mary J. Cloninger, Beilstein Journal of Organic Chemistry, 2015

Abstract Four generations of lactose-functionalized polyamidoamine (PAMAM) were employed to further the understanding of multivalent galectin-1 mediated interactions. Dynamic light scattering and fluorescence microscopy were used to study the multivalent interaction of galectin-1 with the ...

Synthesis of tripodal catecholates and their immobilization on zinc oxide nanoparticles

07-May-2015 | Franziska Klitsche, Julian Ramcke, Julia Migenda, Andreas Hensel, Tobias Vossmeyer, Horst Weller, Silvia Gross and W ..., Beilstein Journal of Organic Chemistry, 2015

Abstract A common approach to generate tailored materials and nanoparticles (NPs) is the formation of molecular monolayers by chemisorption of bifunctional anchor molecules. This approach depends critically on the choice of a suitable anchor group. Recently, bifunctional catecholates, inspired ...

Anomalous diffusion of Ibuprofen in cyclodextrin nanosponge hydrogels: an HRMAS NMR study

19-Nov-2014 | Monica Ferro, Franca Castiglione, Carlo Punta, Lucio Melone, Walter Panzeri, Barbara Rossi, Francesco Trotta and And ..., Beilstein Journal of Organic Chemistry, 2014

Abstract Ibuprofen sodium salt (IP) was encapsulated in cyclodextrin nanosponges (CDNS) obtained by cross-linking of β-cyclodextrin with ethylenediaminetetraacetic acid dianhydride (EDTAn) in two different preparations: CDNSEDTA 1:4 and 1:8, where the 1:n notation indicates the CD to EDTAn ...

Linear-g-hyperbranched and cyclodextrin-based amphiphilic block copolymer as a multifunctional nanocarrier

18-Nov-2014 | Yamei Zhao, Wei Tian, Guang Yang and Xiaodong Fan, Beilstein Journal of Organic Chemistry, 2014

Abstract In this paper, a novel, multifunctional polymer nanocarrier was designed to provide adequate volume for high drug loading, to afford a multiregion encapsulation ability, and to achieve controlled drug release. An amphiphilic, triblock polymer (ABC) with hyperbranched polycarbonsilane ...

Solution processable diketopyrrolopyrrole (DPP) cored small molecules with BODIPY end groups as novel donors for organic solar cells

18-Nov-2014 | Diego Cortizo-Lacalle, Calvyn T. Howells, Upendra K. Pandey, Joseph Cameron, Neil J. Findlay, Anto Regis Inigo, Tell ..., Beilstein Journal of Organic Chemistry, 2014

Abstract Two novel triads based on a diketopyrrolopyrrole (DPP) central core and two 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) units attached by thiophene rings have been synthesised having high molar extinction coefficients. These triads were characterised and used as donor materials ...

Preparation of neuroprotective condensed 1,4-benzoxazepines by regio- and diastereoselective domino Knoevenagel–[1,5]-hydride shift cyclization reaction

06-Nov-2014 | László Tóth, Yan Fu, Hai Yan Zhang, Attila Mándi, Katalin E. Kövér, Tünde-Zita Illyés, Attila Kiss-Szikszai, Balázs ..., Beilstein Journal of Organic Chemistry, 2014

Abstract Condensed O,N-heterocycles containing tetrahydro-1,4-benzoxazepine and tetrahydroquinoline moieties were prepared by a regio- and diastereoselective domino Knoevenagel–[1,5]-hydride shift cyclization reaction of a 4-aryl-2-phenyl-1,4-benzoxazepine derivative obtained from flavanone. ...

An integrated photocatalytic/enzymatic system for the reduction of CO2 to methanol in bioglycerol–water

03-Nov-2014 | Michele Aresta, Angela Dibenedetto, Tomasz Baran, Antonella Angelini, Przemysław Łabuz and Wojciech Macyk, Beilstein Journal of Organic Chemistry, 2014

Abstract A hybrid enzymatic/photocatalytic approach for the conversion of CO2 into methanol is described. For the approach discussed here, the production of one mol of CH3OH from CO2 requires three enzymes and the consumption of three mol of NADH. Regeneration of the cofactor NADH from NAD+ was ...

Loose-fit polypseudorotaxanes constructed from γ-CDs and PHEMA-PPG-PEG-PPG-PHEMA

23-Oct-2014 | Tao Kong, Lin Ye, Ai-ying Zhang and Zeng-guo Feng, Beilstein Journal of Organic Chemistry, 2014

Abstract A pentablock copolymer was prepared via the atom transfer radical polymerization of 2-hydroxyethyl methacrylate (HEMA) initiated by 2-bromoisobutyryl end-capped PPO-PEO-PPO as a macroinitiator in DMF. Attaching PHEMA blocks altered the self-assembly process of the pentablock copolymer ...

Solution phase synthesis of short oligoribonucleotides on a precipitative tetrapodal support

29-Sep-2014 | Alejandro Gimenez Molina, Amit M. Jabgunde, Pasi Virta and Harri Lönnberg, Beilstein Journal of Organic Chemistry, 2014

Abstract An effective method for the synthesis of short oligoribonucleotides in solution has been elaborated. Novel 2'-O-(2-cyanoethyl)-5'-O-(1-methoxy-1-methylethyl) protected ribonucleoside 3'-phosphoramidites have been prepared and their usefulness as building blocks in RNA synthesis on a ...
