Sustainable valorization of paper mill sludge into cellulose nanofibrils and cellulose nanopaper

As a kind of agro-industrial wastes, paper mill sludge (PMS) has posed serious environmental and economic challenges for disposal due to the more stringent regulations and diminishing land availability in recent years. The present study is aimed at providing a sustainable approach to efficiently convert PMS to cellulose nanofibrils (CNFs) and cellulose nanopaper (CNP) by formic acid (FA) hydrolysis pretreatment and the followed micro fluidization. It is found that FA hydrolysis (4-6 h) could swell and shorten PMS fibers, and only two-pass microfluidization is sufficient to get uniform CNFs from the collected cellulose residual. Results indicate that the obtained CNFs show high thermal stability and crystallinity index, surface functionality (ester groups), as well as a high yield of over 75 wt.%. Notably, more than 90 % FA can be recovered and the hydrolyzed sugars could be potentially used to produce platform chemicals (e.g. lactic acid, furfural). Finally, transparent CNP is prepared from the CNFs suspension via a simple vacuum filtration technique. The resultant CNP shows good mechanical properties with the maximum tensile strength and toughness of 106.4 MPa and 6.62 MJ/m(3), respectively. Therefore, the current work provides a green and sustainable method to valorize PMS for the production of valuable CNFs and CNP.

A systematic review of the biodistribution of biomimetic high-density lipoproteins in mice

For the past two decades, biomimetic high-density lipoproteins (b-HDL) have been used for various drug delivery applications. The b-HDL mimic the endogenous HDL, and therefore possess many attractive features for drug delivery, including high biocompatibility, biodegradability, and ability to transport and deliver their cargo (e.g. drugs and/or imaging agents) to specific cells and tissues that are recognized by HDL. The b-HDL designs reported in the literature often differ in size, shape, composition, and type of incorporated cargo. However, there exists only limited insight into how the b-HDL design dictates their biodistribution. To fill this gap, we conducted a comprehensive systematic literature search of biodistribution studies using various designs of apolipoprotein A-I (apoA-I)-based b-HDL (i.e. b-HDL with apoA-I, apoA-I mutants, or apoA-I mimicking peptides). We carefully screened 679 papers (search hits) for b-HDL biodistribution studies in mice, and ended up with 24 relevant biodistribution profiles that we compared according to b-HDL design. We show similarities between b-HDL biodistribution studies irrespectively of the b-HDL design, whereas the biodistribution of the b-HDL components (lipids and scaffold) differ significantly. The b-HDL lipids primarily accumulate in liver, while the b-HDL scaffold primarily accumulates in the kidney. Furthermore, both b-HDL lipids and scaffold accumulate well in the tumor tissue in tumor-bearing mice. Finally, we present essential considerations and strategies for b-HDL labeling, and discuss how the b-HDL biodistribution can be tuned through particle design and administration route. Our metaanalysis and discussions provide a detailed overview of the fate of b-HDL in mice that is highly relevant when applying b-HDL for drug delivery or in vivo imaging applications.

New one-pot synthesis of anti-tuberculosis compounds inspired on isoniazid

A library of thirty N-substituted tosyl N’-acryl-hydrazones was prepared with p-toluenesulfonyl hydrazide, methyl propiolate and different aldehydes in a one-pot synthesis via an aza-Michael reaction. The scope of the reaction was studied, including aliphatic, isoprenylic, aromatic and carbocyclic aldehydes. The prepared collection was tested against Mycobacterium tuberculosis H37Rv. Nine analogs of the collection showed Minimum Inhibitory Concentration <= 10 mu M, of which the most active members (MIC of 1.25 mu M) were exclusively E isomers. In order to validate the mechanism of action of the most active acrylates, we tested their activity on a M. tuberculosis InhA over-expressing strain obtaining MIC that consistently doubled those obtained on the wild type strain. Additionally, the binding mode of those analogs on M. tuberculosis InhA was investigated by docking simulations. The results displayed a hydrogen bond interaction between the sulfonamide and Ile194 and the carbonyl of the methyl ester with Tyr 158 (both critical residues in the interaction with the fatty acyl chain substrate), where the main differences on the binding mode relays on the hydrophobicity of the nitrogen substituent. Additionally, chemoinformatic analysis was performed to evaluate in silico possible cytotoxicity risk and ADME-Tox profile. Based on their simple preparation and interesting antimycobacterial activity profile, the newly prepared aza-acrylates are promising candidates for antitubercular drug development.

Humic acids trigger the weak acids stress response in maize seedlings

Background: Plants primed by humic acids showed physiological and molecular response against different abiotic stresses without the presence of stressor agents (salinity, drought, heavy metal toxicity). It is plausible that humic acids themselves can act as chemical priming substances in plants. We hypothesized that humic acids can trigger the weak acids stress response in cell plants acidifying the cytosol and thus eliciting the transduction signalling response cascade. Methods: The dose-response curves of maize seedlings roots with different concentrations of humic, acetic and salicylic acids determined the most active and inhibitory concentration. These data were further used to evaluate changes on intracellular pH using BCECF-AM probe (2,7-bis(2-carboxyethyl)-5(and 6)-carboxyfluorescein, acetoxymethyl ester) and differential transcription level of genes related to weak stress response in plants by qPCR real time. Results: Humic acids like short chain organic acids decrease the intracellular pH showed by the increased fluorescence of BCECF probe. The drop in cytosolic pH promoted by humic acids was not transient. We observed a high level of protein kinases related to cell energy-sensing and transcription factors associated to transduction of stress signalling. Conclusion: The humic acids can be considered as a chemical priming agent, since in the appropriate concentration they can induce the typical plant abiotic stress response of weak acids inducing plant acclimation and enhancing the abiotic stress tolerance.

Generation of Sulfonylated Tetrazoles through an Iron-Catalyzed Multicomponent Reaction Involving Sulfur Dioxide

As a privileged motif, tetrazoles can be widely found in pharmaceuticals and materials science. Herein, a five-component reaction of cycloketone oxime esters, alkynes, DABCO center dot(SO2)(2), and two molecules of trimethylsilyl azide under iron catalysis is developed, giving rise to a range of cyano-containing sulfonylated tetrazoles in moderate to good yields. This multicomponent reaction exhibits excellent selectivity and enables the formation of multiple new chemical bonds in one pot. A possible mechanism involving azidosulfonylation of alkynes, C-C bond cleavage of both cycloketone oxime esters and alkynes, and [3 + 2] cycloaddition of trimethylsilyl azide and the nitrilium cation intermediate is proposed. Additionally, the potential of terminal alkynes acting as powerful synthons for the synthesis of tetrazoles in a radical initiated process is demonstrated for the first time.

Catalytic Asymmetric Mannich-Type Reaction Enabled by Efficient Dienolization of alpha,beta-Unsaturated Pyrazoleamides dagger

Main observation and conclusion (E)-alpha,beta-Unsaturated pyrazoleamides undergo facile dienolization to furnish copper(I)-(1Z,3Z)-dienolates as the major in the presence of a copper(I)-(R)-DTBM-SEGPHOS catalyst and Et3N, which react with aldimines to afford syn-vinylogous products as the major diastereoisomers in high regio- and enantioselectivities. In some cases, the diastereoselectivity is low, possibly due to the low ratio of copper(I)-(1Z,3Z)-dienolates to copper(I)-(1Z,3E)-dienolates. (Z)-Allylcopper(I) species is proposed as effective intermediates, which may form an equilibrium with copper(I)-(1Z,3Z)-dienolates. Interestingly, the present methodology is a nice complement to our previous report, in which (E)-beta,gamma-unsaturated pyrazoleamides were employed as the prenucleophiles in the copper(I)-catalyzed asymmetric vinylogous Mannich-Type reaction and anti-vinylogous products were obtained. In the previous reaction, copper(I)- (1Z,3E)-dienolates were generated through alpha-deprotonation, which might form an equilibrium with (E)-allylcopper(I) species. Therefore, it is realized in the presence of a copper(I) catalyst that (E)-alpha,beta-unsaturated pyrazoleamides lead to syn-products and (E)-beta,gamma-unsaturated pyrazoleamides lead to anti-products. Finally, by use of (E)-beta,gamma-unsaturated pyrazoleamide, (E)-alpha,beta-unsaturated pyrazoleamide, (R)-DTBM-SEGPHOS, and (S)-DTBM-SEGPHOS, the stereodivergent synthesis of all four stereoisomers is successfully carried out. Then by following a three-step reaction sequence, all four stereoisomers of N-Boc-2-Ph-3-Me-piperidine are synthesized in good yields, which potentially serve as common structure units in pharmaceutically active compounds.

Injectable Hypoxia-Induced Conductive Hydrogel to Promote Diabetic Wound Healing

Injectable hydrogels with the capability to cast a hypoxic microenvironment is of great potentialities to develop novel therapies for tissue regeneration. However, the relative research still remains at the conceptual phase. Herein, we chose diabetic wound as a representative injury model to explore the actual therapeutic results of tissue injury by injectable hypoxia-induced hydrogels. To enhance recovery and widen applicability, the hypoxia-induced system was incorporated with a conductive network by an original sequentially interpenetrating technique based on the combination of a fast click chemistry and a slow enzymatic mediated cross-linking. Hyperbranched poly(beta-amino ester)-tetraaniline (PBAE-TA) was cross-linked with thiolated hyaluronic acid (HA-SH) via a thiol-ene click reaction, contributing to the rapid formation of the first conductive network, where vanillin-grafted gelatin (Geln-Van) and laccase (Lac) with a slow cross-linking rate were employed in casting a hypoxic microenvironment. The as-prepared injectable hydrogels possessed both suitable conductivity and sustainable hypoxia-inducing capability to upregulate the hypoxia-inducible factor-la and connexin 43 expressions of the encapsulated adipose-derived stem cells, which enhanced vascular regeneration and immunoregulation and further promoted the reconstruction of blood vessels, hair follicles, and dermal collagen matrix, eventually leading to the recovery of diabetic rat skin wounds and restoration of skin functions. This work provides a promising strategy to broaden the applicability of diverse hydrogels with a long time-consuming gelation process and to integrate different networks with various biological functions for the therapies of diabetic wounds and other complex clinical symptoms.

Factor XII/XIIa inhibitors: Their discovery, development, and potential indications

Coagulation factor XII (FXII), a S1A serine protease, was discovered more than fifty years ago. However, its in vivo functions and its three-dimensional structure started to be disclosed in the last decade. FXII was found at the crosstalk of several physiological pathways including the intrinsic coagulation pathway, the kallikrein-kinin system, and the immune response. The FXII inhibition emerges as a therapeutic strategy for the safe prevention of artificial surface-induced thrombosis and in patients suffering from hereditary angioedema. The anti-FXII antibody garadacimab discovered by phage-display library technology is actually under phase II clinical evaluation for the prophylactic treatment of hereditary angioedema. The implication of FXII in neuro-inflammatory and neurodegenerative disorders is also an emerging research field. The FXII or FXIIa inhibitors currently under development include peptides, proteins, antibodies, RNA-based technologies, and, to a lesser extent, small-molecular weight inhibitors. Most of them are proteins, mainly isolated from hematophagous arthropods and plants. The discovery and development of these FXII inhibitors and their potential indications are discussed in the review. (c) 2020 Elsevier Masson SAS. All rights reserved.

Fine root biomass stimulates microbial activity of glucose mineralization in buried humic horizon of volcanic ash soils

Burial of the surface soil by volcanic ash deposition plays roles in organic matter accumulation. Assuming that decomposition of the buried humus is limited solely by labile substrate inputs, glucose inputs are hypothesized to stimulate microbial activity in buried humic horizons. We describe patterns of microbial mineralization of C-14-labeled glucose in volcanic soil profiles to test whether glucose inputs increase microbial activity similarly in the surface soil and buried humic horizons. We found that microbial biomass was dependent on fine root biomass rather than soil carbon concentration in the volcanic soil profiles. Both bacterial and fungal biomass correlated with fine root biomass. The microbial capacities of glucose mineralization in the buried humic horizons were lower than in the surface horizons. The microbial activity of glucose mineralization in the buried humic horizons is limited by (1) the smaller microbial biomass due to smaller fine root biomass and (2) the dominance of microbial community adapted to the low concentrations of substrates with low mineralization capacity. Stimulation of microbial activities in the buried humic horizons requires both fine root biomass and inputs of labile substrates.

Improving Oxidative Stability and Sensory Properties of Ale Beer by Enrichment with Dried Red Raspberries (Rubus idaeus L.)

Red raspberry has attracted great interest due to its inherent antioxidant, anticarcinogenic, and antihyperglycemic effects. To brew a beverage with high antioxidant capacity and desirable sensory characteristics (malty aroma, hop aroma, fruit flavor, freshness, fullness, sweetness, sourness, and bitterness), dried red raspberries (Rubus idaeus L.) (30 g L-1 wort) were added to beer at different stages of the brewing process (beginning of boiling, before fermentation, before conditioning) and compared to a control without added dried fruits. The beer was fermented with Saccharomyces cerevisiae for 7 days at 18 degrees C followed by a secondary fermentation of 3 days at 20 degrees C. The main physicochemical attributes (original gravity, ethanol content, pH, color, colloidal haze, viscosity, bitterness, diacetyl, acetaldehyde, higher alcohols, and esters), sensory characteristics, and major bioactive compounds were determined. A decline in pH and an increase in color were observed in the raspberry beers. Adding dried fruits at the beginning of boiling imparted the highest oxidative stability and total phenolic and flavonoid content (696 mg GAE L-1 and 510 mg QE L-1, respectively). Sensory analysis revealed that the most preferred product according to appearance, flavor, and taste was the beer with dried fruits added at the beginning of boiling.
