The commercially available linear polyimide Matrimid((R)) 9725 was crosslinked with amino groups containing both high-molecular-weight and low-molecular-weight compounds. The multi-functional amine-terminated hyperbranched polyimide precursor (hyperbranched polyamic acid), based on 4,4-(hexafluoroisopropylidene)diphthalic anhydride and 4,4,4-triaminotriphenylmethane, and its fully imidized form (amine-terminated hyperbranched polyimide), bifunctional amine, 4,4-diaminodiphenylamine and trifunctional amine, 4,4,4-triaminotriphenylamine, were used as the crosslinkers. Theoretically, 10% or 20% of the Matrimid imide groups was reacted with the amino groups of the crosslinking agent during the formation of the amide groups. The insoluble content (gel) in the final materials was very low at the crosslinking temperature of 80 degrees C and was in the 55-90% range at the crosslinking temperature of 200 degrees. The permeability coefficients of hydrogen, carbon dioxide and methane in the self-standing, mechanically tough film (membrane) based on the combination of Matrimid and hyperbranched polyimide were approximately 30-45% higher compared with those in the membrane made of pure Matrimid at a comparable separating ability (selectivity).

Self-assembly of metal-organic coordination polymers occurs because of enthalpically favorable interactions. In the case of the bulky 4,4′-(anthracene-9,10-diyl) dibenzoic acid ligand (abdH(2)), we demonstrate that the presence of numerous pi-pi and C-H center dot center dot center dot pi interactions outweigh the formation of saturated coordination complexes with zinc, leading to the formation of a dimethylformamide (DMF) solvate, namely 4,4′-(anthracene-9,10-diyl) dibenzoic acid dimethylformamide disolvate, C28H18O4 center dot 2C(3)H(7)NO or [(abdH(2))(DMF)(2)], at low concentrations of zinc. Meanwhile, at higher zinc concentrations, the abdH(2) ligand gives rise to the nonporous one-dimensional coordination polymer catena-poly[[bis(dimethylformamide-kappa O) zinc(II)]-mu-4,4′-(anthracene-9,10-diyl)dibenzoato-kappa(2) O:O’], [Zn(C28H16O4)(C3H7NO)(2)] n or [Zn(abd)(DMF)(2)](n), when assembled in dimethylformamide, while a related compound is observed when N, N-dimethylacetamide (DMA) is used as the solvent, namely catenapoly[[[ bis(N, N-dimethylacetamide-kappa O) zinc(II)]-mu-4,4′-(anthracene-9,10-diyl) dibenzoato-kappa(2) O:O’] N, N-dimethylacetamide monosolvate], {[Zn(C28H16O4)(C4H9NO)(2)]center dot C4H9NO}(n) or {[Zn(abd)(DMA)(2)] center dot DMA}(n). Attempts to use other amide-based solvents did not give rise to any other assembled structures.

Multidrug resistance (MDR) is one of the major obstacles hindering the successful chemotherapy of cancer. Overexpression of drug efflux transporters such as P-glycoprotein (P-gp) is an important factor responsible for MDR. In this study, a novel copolymer methoxy-poly(ethylene glycol)-poly[(N-(6-hydroxyhexyl)-g-doxorubicin-l-aspartamide)-(-benzyl-l-aspartate)] (mPEG-P[Asp(HPA-g-DOX)-BLA)] was synthesized and utilized to assemble into nanovesicles with hydrophilic P-gp inhibitor elacridar hydrochloride (Ela) encapsulated into the aqueous lumen. Doxorubicin (DOX) was covalently conjugated onto the polymer chain via a pH-cleavable amide linkage, leading to a pH responsive DOX release as well as disintegration of the nanovesicles in the lysosome of tumor cells. In vitro studies demonstrated that the DOX and Ela co-delivered nanovesicles showed superior cytotoxicity and enhanced anti-tumor properties as compared to single DOX-delivery nanosystems in MCF-7/ADR cancer, which was attributed to the P-gp bioactivity inhibition as investigated by a cell immunofluorescence assay. In vivo studies showed that the polymeric nanovesicles effectively accumulated at the tumor site and the co-delivered DOX and Ela effectively suppressed the MCF-7/ADR tumor growth. All the results indicated that the acid-liable nanovesicles had a synergistic effect to enhance antitumor efficacy for multidrug-resistant breast cancer treatment.

1,6-Hexylenediamine (HMDA) was chosen to replace part of ethylene glycol to develop a novel poly(ethylene terephthalate) structure with amide bonds. Four kinds of poly(ester amide)analogues (p-ETA) with different contents of amide bonds (1-4 mol %) were successfully synthesized via a new simple synthesis procedure. It was proved that the thermal stability and mechanical properties were significantly enhanced because of the introduction of amide bond units. More importantly, adding a small amount (1 mol %) of HMDA could effectively accelerate the orderly arrangement of molecular chains and formation of crystal nuclei proved by differential scanning calorimetry, X-ray diffraction, and polarized optical microscopy test results. It showed that the calendered p-ETA films acted as a good barrier to water and oxygen, expanding its application as packaging materials. Experimental results indicated that the introduction of amide bond units substantially promoted the overall performances of poly(ethylene terephthalate), such as crystallinity (28.4 vs 14.1%), tensile strength (60.9 vs 55.7 MPa), elongation at break (381 vs 226.8%), and so forth.

Abri herba originates from Abrus mollis and Abrus cantoniensis. Its leaves are rich in amides and they are often used as folk food ingredients and tea in China. However, the effective analysis methods for amides have not been reported. An UPLC method was developed to obtain the fingerprint profiles and to quantify these amides. Twenty common peaks were identified and analyzed by similarity, hierarchical clustering, and principal component analysis of UPLC fingerprints from 24 samples. Furthermore, four amides were simultaneously quantitated by Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Heat Map. The similarity of the fingerprints ranged from 0.734 to 0.989. The contents of amides were affected by the origins of the samples, and the closer the origin, the higher similarity of amide profiles. (E)-N-(4-hydroxycinnamoyl) tyrosine was the major compound ranging from 0.75 to 6.36 mg g(-1), followed by abrusamide A (0.44 similar to 1.14 mg g(-1)), abrusamide B (0.35 similar to 0.75 mg g(-1)), and abrusamide C (0.05 similar to 0.25 mg g(-1)). This is the first report to fingerprints and quantification analytical method of amides in leaves of abri herba.

Phosphorylation on the early earth

Phosphorus is an element critical to the formation of several biomolecules, including nucleic acids, the energy transfer molecule ATP, and phospholipids. It hence lies at the heart of several biomolecular functions. However, the formation of these key biomolecules is hindered by the geochemical properties of phosphorus, including its low solubility and poor reactivity. Here we review the approaches that have been taken to overcome some of these difficulties, and place them in the context of the geochemistry of the early earth. We find many experiments rely on phosphate minerals unlikely present on the Hadean earth, or employ conditions that depend on unusual geochemical environments. We propose the most likely routes to forming organophosphate molecules in the context of a plausible prebiotic geochemistry may rely instead on ephemeral phosphate minerals, or redox reactions of phosphorus to form the necessary soluble and reactive phosphorus reagents.

An overview of anion coordination by hydroxyl, amine and amide based rigid and symmetric neutral dipodal receptors

The last two decades have witnessed some modified approach in designing supramolecular anion receptors, not only for academic interests but also for their potential applications in biology and environment. Although, most of the tripodal based anion receptors are extensively studied in literature in a compact way, but the systematic and well-documented anion recognition study by dipodal receptors is still unexplored. The review aims to provide a detailed and comprehensive account of reported examples over last two decades of anion coordinated neutral self-assemblies of artificial dipodal receptors that employ several non-covalent interactions offered by specific low coordinating binding sites such as hydroxyl, amine, amide, thiamide, sulfonamide itself as well as from their hybrid functionalities such as amine-amide, amine-hydroxyl, amidehydroxyl, hydroxyl-sulfonamide, amine-sulfonamide etc. This review specifically targets the rigid as well as symmetric dipodal backbone of anion receptors/sensors that discuss either the solid state structural aspects and/or the solution phase host-guest binding phenomena. Typical examples of anion-coordinated self-assembled supramolecular architectures including molecular barrel, capsules, foldamer, helicates, tetrahedral cages, mechanically interlocked systems as well as some colorimetric, chromogenic and fluorogenic chemosensors developed from covalently connected rigid dipodal low coordinating scaffolds are summarized other than high coordinating urea, thiourea scaffolds. Discussions relating to some potential applications in anion recognition, selective and sensitive anion sensing, cell imaging studies, transmembrane anion transport etc. as demonstrated by some of these dipodal receptors have also been included in this review.

Twofold C-H Activation Enables Synthesis of a Diazacoronene-Type Fluorophore with Near Infrared Emission Through Isosteric Replacement

The synthesis and photophysical properties of a soluble amide-embedded coronene is reported. The key step in this synthesis is the twofold C-H activation of diazaperylene by a rhodium(III)Cp* catalyst. This unprecedented structural motif shows intense fluorescence in the near infrared region with a small Stokes shift and a distinct vibronic structure, which exhibits a slight extent of negative solvatochromism. Comparison of this compound with some relevant compounds revealed the importance of the amide incorporation in the peripheral concave region including an angular position to retain high aromaticity reflecting that of parent coronene. Treatment of this compound with Lewis acid B(C6F5)(3) formed a bis-adduct, which exhibited enhanced aromaticity as a consequence of the increased double bond character of the amide C-N bonds.

Effect of feed pressure and long-term separation performance of Pebax-ionic liquid membranes for the recovery of difluoromethane (R32) from refrigerant mixture R410A

The R410A refrigerant blend (GWP = 2088), a near azeotropic and equimass mixture of difluoromethane (R32, GWP = 675) and pentafluoroethane (R125, GWP = 3500), has been included in the HFC phase down road map established worldwide. In this context, the recovery of value-added R32 from R410A using membrane technology would be a breakthrough in the refrigeration and air conditioning sector, given that conventional distillation cannot be applied to this separation. For the first time, this work has taken advantage of the combination of ionic liquids and polymeric membranes for the separation of the constituents of the R410A mixture. Results show a remarkable improvement in terms of R32 permeability and R32/R125 selectivity in the composite membranes containing 40 wt % [C(2)mim][SCN] (alpha(R32/R125) up to 14.5) and [C(2)mim][BF4] (alpha(R32/R125) up to 11.0) with respect to the neat polymer membranes (alpha(R32/R125) up to 6.9). Besides, the long-term stability was successfully tested for 25 days under high pressure conditions (7 and 12 bar), which makes these composite membranes excellent candidates for the development of membrane-based R32 separation and recovery processes.
