Abstract
In this communication, we describe our preliminary results for the development of a new method of ethylene and propene (co)polymerization at low pressure at room temperature, using cyclodextrin-assisted aqueous radical polymerization for the first time. For polypropylene homopolymerization, the cyclodextrin was entirely removed, and the partially soluble polymer was characterized. The purification of polyethylene was not complete, since the threaded cyclodextrins remained on the polymer chain, enhancing its solubility and enable to analyze the sample. With this environmentally benign method, polyolefines could be produced, for the first time. The estimated yield was low, and therefore the conditions should be further tuned for industrial application. This straightforward approach could also be applied to synthesize poly(ethylene-co-vinyl acetate) copolymer with an ethylene content of 20 mol% and enhanced yield. Although the procedure in this stage of research has some limitations, the theory behind can later be applied to develop new, energy-efficient, and versatile industrial processes for olefin copolymerizations for a wide range of comonomers.

Abstract
The aqueous reversible addition fragmentation chain-transfer (RAFT) copolymerization of isoprene and bulky comonomers, an acrylate and an acrylamide in the presence of methylated β-cyclodextrin was employed for the first time to synthesize block-copolyrotaxanes. RAFT polymerizations started from a symmetrical bifunctional trithiocarbonate and gave rise to triblock-copolymers where the outer polyacrylate/polyacrylamide blocks act as stoppers for the cyclodextrin rings threaded onto the inner polyisoprene block. Statistical copolyrotaxanes were synthesized by RAFT polymerization as well. RAFT polymerization conditions allow control of the composition as well as the sequence of the constituents of the polymer backbone which further effects the CD content and the aqueous solubility of the polyrotaxane.

Abstract
The objective of this study was the syntheses of well-defined glycodendrimer with entrapment efficiency by click reactions, with β-cyclodextrins (β-CDs) moiety to keep the biocompatibility properties, besides especially increase their capacity to load numerous appropriate sized guests. The original dendrimer containing β-CD in both periphery and central was synthesized using click reaction. The entrapment property of the β-CD-dendrimer was studied by methotrexate (MTX) drug. The chemical structure of β-CD-dendrimer was characterized by (1)H NMR, (13)C NMR and FTIR and its inclusion complex structure were investigated by SEM, DLS, DSC and FTIR techniques. The cytotoxic effect of obtained compound and its inclusion complex with MTX was analyzed using MTT test. The MTT test exhibited that the synthesized compound was not cytotoxic to the cell line considered. The in vitro drug release study turned out that the obtained β-CD dendrimer could be a suitable controlled drug delivery system for cancer treatment.

Abstract
The aim of this work was the synthesis of biodendrimeric β-cyclodextrin (β-CD) on the secondary face with encapsulation efficacy, with β-CDs moiety to preserve the biocompatibility properties, also particularly growth their loading capacity for drugs with certain size. The new dendrimer, having 14 β-CD residues attached to the core β-CD in secondary face (11), was prepared through click reaction. The encapsulation property of the prepared compound was evaluated by methotrexate (MTX) drug molecule. Characterization of compound 11 was performed with (1)H NMR, (13)C NMR and FTIR and its supramolecular inclusion complex structure was determined using FTIR, DLS, DSC and SEM techniques. In vitro cytotoxicity test results showed that compound 11 has very low or no cytotoxic effect on T47D cancer cells. In vitro drug release study at pHs 3, 5 and 7.4 showed that the release process was noticeably pH dependent and the dendrimer could be used as an appropriate controlled drug delivery system (DDS) for cancer treatment.

Abstract
In our previous work we have described the synthesis, characterization, and optimization of the chromatographic efficiency of a highly crosslinked macroporous mixed-mode acrylamide-based monolithic stationary phase synthesized by in situ free radical copolymerization of cyclodextrin-solubilized N-adamantyl acrylamide, piperazinediacrylamide, methacrylamide and vinylsulfonic acid in aqueous medium in pre-treated fused silica capillaries of 100μm I.D. In the present work, we study with different classes of neutral analytes (with varied hydrophobicity) the impact of the type of retention mode (influenced by the type of analyte and the mobile phase composition) and the impact of the solute functionality on the chromatographic efficiency and peak symmetry with a monolith synthesized under optimized synthesis parameters. With this monolithic capillary high separation efficiencies (up to ca. 220,000m(-1)) are obtained for the separation of different analyte classes (alkylphenones, nitrotoluenes, and phenolic compounds with k=0.2-0.55) in the reversed-phase mode, in the normal-phase mode, and in the mixed mode. For neutral alkylanilines (k<0.25) plate numbers of about 300,000m(-1) are routinely reached in the reversed-phase elution mode. For phenolic solutes separated in a mixed mode there is a solute-specific influence on peak symmetry and chromatographic efficiency. With increasing efficiency of the monolith, axial diffusion becomes an important mechanism of band broadening. For those peaks, which do not show a significant asymmetry (asymmetry factor ≤1.05), it is confirmed that plate heights gained via the tangent method are equivalent to those gained via moment analysis.

This twofold alkylation was performed in aqueous solution, whereby α-, and randomly methylated β-cyclodextrin were used as adequate phase transfer catalysts and the cyclodextrin–guest complexes were characterized by 1H NMR and 2D NMR ROESY spectroscopy. Finally, the curing properties of the diepoxide with lysine-based α-amino-ε-caprolactam were analyzed by rheological measurements.

Abstract
The study presents the possibility to use the 2-hydroxyethyl methacrylate--HEMA copolymer with a comonomer with spiroacetal moiety, 3,9-divinyl-2,4,8,10-tetraoxaspiro[5.5]-undecane)-U, as polymer network for loading the indomethacin--INN as drug model, and also, the controlled release evaluation of the prepared bioactive system. The macromolecular compounds were prepared by radical dispersion polymerization in the presence of a pair of surfactants. The use of cyclodextrin as surfactant allowed the building of the host-guest complexes by inclusion of hydrophobic molecules. Also, the cyclodextrin supplemented the hydrogen bonds and the hydrophobic interactions responsible for the stability of the achieved complexes. The copolymers composition and the INN inclusion onto the polymeric matrix were confirmed by FTIR analysis. The porous structure of the lyophilized P(HEMA-U) samples was illustrated by SEM images. The swelling studies evidenced the interdependence between P(HEMA-U) network properties and the spiroacetal moiety amount. Thus, the copolymers presented the increase of the equilibrium swelling degree with pH and temperature. Also, the polymeric matrices manifested dual sensitivity with pH and temperature. The in vitro release of the INN drug from the polymeric network as well as the in vivo experimental studies evidenced the benefit consequence of the spiroacetal compound presence. The clinical observation of the experimental groups does not show any behavioral modifications to suggest a possible toxic effect of these polymeric formulations with and without INN.

Abstract
The potential of appropriately substituted cyclodextrins to act as scavengers for neurotoxic organophosphonates under physiological conditions was evaluated. To this end, a series of derivatives containing substituents with an aldoxime or a ketoxime moiety along the narrow opening of the β-cyclodextrin cavity was synthesized, and the ability of these compounds to reduce the inhibitory effect of the neurotoxic organophosphonate cyclosarin on its key target, acetylcholinesterase, was assessed in vitro. All compounds exhibited a larger effect than native β-cyclodextrin, and characteristic differences were noted. These differences in activity were correlated with the structural and electronic parameters of the substituents. In addition, the relatively strong effect of the cyclodextrin derivatives on cyclosarin degradation and, in particular, the observed enantioselectivity are good indications that noncovalent interactions between the cyclodextrin ring and the substrate, presumably involving the inclusion of the cyclohexyl moiety of cyclosarin into the cyclodextrin cavity, contribute to the mode of action. Among the nine compounds investigated, one exhibited remarkable activity, completely preventing acetylcholinesterase inhibition by the (−)-enantiomer of cyclosarin within seconds under the conditions of the assay. Thus, these investigations demonstrate that decoration of cyclodextrins with appropriate substituents represents a promising approach for the development of scavengers able to detoxify highly toxic nerve agents.

Abstract
A new method to adjust the particle size of interpolymer complexes has been developed by introduction of host-guest interaction into the dilute aqueous solution of poly(acrylic acid) (PAA) and poly(ethylene glycol) (PEG). Because of the cooperative hydrogen-bonding interaction, PAA can form the interpolymer complexes with PEG. Putting beta-cyclodextrin (beta-CD) into dilute PAA/PEG aqueous solution, the competition between host-guest and hydrogen-bonding interactions happens. The beta-CD/PAA/PEG ternary systems have been well characterized by ultraviolet-visible absorption spectroscopy (UV-vis), dynamic light scattering (DLS), transmission electron microscopy (TEM), diffusion NMR spectroscopy, attenuated total reflectance-Fourier transform infrared (ATR-FTIR), and solid-state (13)C NMR spectroscopy. The results indicate that the hydrophobic cavity of beta-CD is threaded by linear polymers so that the hydrophilicity of PAA/PEG interpolymer complexes is improved greatly. Adjusting the amounts of beta-CD, the particle size of the interpolymer complexes can be readily controlled. The low cytotoxicity of various beta-CD/PAA/PEG ternary complexes has been confirmed using the MTT assay in COS-7 cell line. Doxorubicin (DOX), an anticancer drug, has been encapsulated into the beta-CD/PAA/PEG ternary complexes. The DOX-loaded beta-CD/PAA/PEG ternary complexes have been analyzed by confocal laser scanning microscopy (CLSM), flow cytometry analysis, and the MTT assay against human cervical carcinoma cell (Hela). The results indicate that beta-CD/PAA/PEG ternary complexes with controlled particle size could be used as safe and promising drug carriers.

Abstract
The host-guest complexation between an Alexa 488 labelled adamantane derivative and beta-cyclodextrin is studied by Fluorescence Correlation Spectroscopy (FCS). A 1:1 complex stoichiometry and a high association equilibrium constant of K = 5.2 x 10(4) M(-1) are obtained in aqueous solution at 25 degrees C and pH = 6. The necessary experimental conditions are discussed. FCS proves to be an excellent method for the determination of stoichiometry and association equilibrium constant of this type of complexes, where both host and guest are nonfluorescent and which are therefore not easily amenable to standard fluorescence spectroscopic methods.
