Mol. assemblies, namely, polyelectrolyte complexes (PECs) composed of neg. charged xylan-based derivatives and a novel pos. charged cellulose derivative (CN⁺), were used for interfacial modification of wood fibers by charge directed self-assembly. The adsorption process was studied using polyelectrolyte titration and elemental anal. X-ray spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) were used as advanced techniques for the characterization of the modified fiber surfaces. The measurements revealed an intense interaction between the pulp fibers and PECs, and provided essential information for a better understanding of the adsorption process. The information gathered on this paper might contribute to the basis for the development of new value added products by the use of underutilized biomass.

Vega, Beatriz published the artcilePreparation of reactive fiber interfaces using multifunctional cellulose derivatives, Computed Properties of 6249-56-5, the publication is Carbohydrate Polymers (2015), 261-273, database is CAplus and MEDLINE.

Cellulose fibers have poor reactivity and limited potential for surface engineering with advanced chem. functionalization in water. In this work, cellulose fibers were decorated with azide functions by charge-directed self-assembly of a novel water-soluble multifunctional cellulose derivative yielding reactive fibers. Propargylamine and 1-ethynylpyrene were utilized as a proof of concept that alkyne mols. may react with the azide functions of the reactive fibers via copper(I)-catalyzed azide-alkyne Huisgen cycloaddition (CuAAc) reaction in mild conditions. Chem. characterization of the fibers was carried out using classical techniques such as Raman-, fluorescence-, and UV-vis spectroscopy. Among other techniques, time-of-flight secondary ion mass spectrometry (ToF-SIMS), X-ray spectroscopy (XPS), two-photon microscopy (TPM), and inductively coupled plasma mass spectrometry (ICP-MS) were useful tools for addnl. characterization of the fibers decorated with amino- or photoactive groups. The information gathered in this work might contribute to the basis for the preparation of reactive cellulose-based interfaces with potential application in CuAAc reactions.

Grigoray, Olga published the artcileFluorescent Multifunctional Polysaccharides for Sustainable Supramolecular Functionalization of Fibers in Water, Computed Properties of 6249-56-5, the publication is ACS Sustainable Chemistry & Engineering (2017), 5(2), 1794-1803, database is CAplus.

The paper describes the synthesis of multifunctional cellulose derivatives (MCD) containing a fluorescent- and a cationic moiety and their application in the functionalization of pulp fibers. The cellulose derivatives, namely N-(3-propanoic acid)- and N-(4-butanoic acid)-1,8-naphthalimide esters of cellulose, differed in the degree of substitution (DS) and by the aliphatic chain connecting naphtalimide photoactive groups to the polymer backbone. The derivatives were decorated with a cationic moiety, namely (3-carboxypropyl)trimethylammonium chloride. The fluorescent pulp fibers were prepared by direct self-assembly of the water-soluble fluorescent MCDs on the fibers in water at room temperature The results indicated that the adsorption was mainly driven by ion exchange mechanism. UV-vis- and fluorescence spectroscopic studies showed that the adsorption yield of the fluorescent MCDs depended on the length of the aliphatic chain of the photoactive groups. Because of the adsorption, the modified pulp fibers gained fluorescence in the visible part of the spectrum. Under the black light illumination, the modified fibers fluoresced, which made them visually distinguishable from the reference fibers. Thus, the fluorescent pulp fibers prepared in a simple way can be potentially used in fiber-based photoactive materials and authenticity indicators in papers and packaging.

Myriad nanocarriers have been developed to improve the therapeutic index of low-mol.-weight drugs for cancer treatment, but many have suboptimal size and/or are too stable for optimal penetration into tumors and their subsequent excretion from the body. To address this challenge, we developed a series of novel nanocarriers based on star polymers consisting of hydrophilic poly[N-(2-hydroxypropyl)methacrylamide] (PHPMA) or poly(ethylene glycol) (PEG) polymer arms attached to hexavalent cyclotriphosphazene (CTP)-derived cores through either stable or stimuli-responsive linkers. The star polymers were assembled using either “grafting from” or “grafting onto” approaches and characterized by quant. arm substitution at the core. The resulting star polymers were precisely defined water-soluble nanomaterials with a suitable hydrodynamic size (~10-25 nm) for tumor uptake; those with stimuli-responsive linkers exhibited programmable pH- or cathepsin-mediated degradability. Finally, low-mol.-weight drugs-an anthracycline-based cancerostatic and an imidazoquinoline-based immunostimulant-were linked to exemplary CTP-based star polymers to demonstrate their suitability for drug delivery.

Grunwald, Marco Andre published the artcileColumnar Propeller-Like 1,3,5-Triphenylbenzenes: Probing the Effect of Chlorine on the Suzuki Cross-Coupling and Liquid Crystalline Properties, Category: chlorides-buliding-blocks, the publication is European Journal of Organic Chemistry (2020), 2020(15), 2190-2198, database is CAplus.

Suzuki cross-couplings either between chlorinated N-methyliminodiacetic acid (MIDA)-protected aryl boronates and 1,3,5-tribromobenzene or between chlorinated aryl bromides and phenyltrisboronic species to star-shaped 1,3,5-triphenylbenzenes with different substitution patterns and chloro substituents at the outer Ph rings were studied. The chlorinated precursors required for the resp. reaction were synthesized and characterized. Depending on the used coupling reaction target triphenylbenzenes were isolated in yields between 42% and 88%. Their mesomorphic properties were influenced by the substitution pattern and number of peripheral chlorine atoms. Triphenylbenzene with 3,5-alkoxy substitution and H in para-position self-assembled into either columnar hexagonal (Col_h) mesophases or a soft crystal. While threefold chloro substitution in meta-position of the outer Ph rings led to stable room temperature Col_ho phases, triphenylbenzenes with threefold para-chloro or 3,5-dichloro substitution were non-mesomorphic. Based on x-ray diffraction data a helical packing model for the observed phases similar to that of related alkoxy-substituted triphenylbenzenes is proposed.

Liu, Congxing published the artcileNewly developed CK1-specific inhibitors show specifically stronger effects on CK1 mutants and colon cancer cell lines, Recommanded Product: 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is International Journal of Molecular Sciences (2019), 20(24), 6184, database is CAplus and MEDLINE.

Protein kinases of the CK1 family can be involved in numerous physiol. and pathophysiol. processes. Dysregulated expression and/or activity as well as mutation of CK1 isoforms have previously been linked to tumorigenesis. Among all neoplastic diseases, colon and rectal cancer (CRC) represent the fourth leading cause of cancer related deaths. Since mutations in CK1δ previously found in CRC patients exhibited increased oncogenic features, inhibition of CK1δ is supposed to have promising therapeutic potential for tumors, which present overexpression or mutations of this CK1 isoform. Therefore, it is important to develop new small mol. inhibitors exhibiting higher affinity toward CK1δ mutants. In the present study, we first characterized the kinetic properties of CK1δ mutants, which were detected in different tumor entities. Subsequently, we characterized the ability of several newly developed IWP-based inhibitors to inhibit wild type and CK1δ mutants and we furthermore analyzed their effects on growth inhibition of various cultured colon cancer cell lines. Our results indicate, that these compounds represent a promising base for the development of novel CRC therapy concepts.
