Environmental assessment, mechanical behavior, and chemical properties of self-compacting mortars (SCMs) with harbor dredged sediments to be used in construction.

Environ Sci Pollut Res Int 2021 Jun 14. Epub 2021 Jun 14.

University Lille, ULR 4515 - LGCgE, Laboratoire de Génie Civil et géo-Environnement, F-59000, Lille, France.

Environmental and ecological issues have led to the development of new sustainable channels for the recovery of dredged sediments. One of the major difficulties of sediment valorization lies in particular in its very heterogeneous composition. For example, the presences of heavy metals and organic matter have a significant influence on the environmental impact of materials formulated with sediment. Read More

Multifunctional ionic porous frameworks for CO conversion and combating microbes.

Chem Sci 2020 Jul 6;11(30):7910-7920. Epub 2020 Jul 6.

Department of Chemistry, Indian Institute of Science Education and Research Bhopal Bhopal Bypass Road, Bhauri Bhopal 462066 Madhya Pradesh India

Porous organic frameworks (POFs) with a heteroatom rich ionic backbone have emerged as advanced materials for catalysis, molecular separation, and antimicrobial applications. The loading of metal ions further enhances Lewis acidity, augmenting the activity associated with such frameworks. Metal-loaded ionic POFs, however, often suffer from physicochemical instability, thereby limiting their scope for diverse applications. Read More

Uncovering potential interspecies signaling factors in plant-derived mixed microbial culture.

Bioorg Med Chem 2021 Jun 4;42:116254. Epub 2021 Jun 4.

Biochemistry Ph.D. Program, The Graduate Center of CUNY, 365 5(th) Ave, New York, NY 10016, USA; Chemistry Ph.D. Program, The Graduate Center of CUNY, 365 5(th) Ave, New York, NY 10016, USA; Department of Chemistry, Hunter College of CUNY, 695 Park Ave, New York, NY 10065, USA.

Microbes use signaling factors for intraspecies and interspecies communications. While many intraspecies signaling factors have been found and characterized, discovery of factors for interspecies communication is lagging behind. To facilitate the discovery of such factors, we explored the potential of a mixed microbial culture (MMC) derived from wheatgrass, in which heterogeneity of this microbial community might elicit signaling factors for interspecies communication.

Enhancement of the Tolerogenic Phenotype in the Liver by ImmTOR Nanoparticles.

Front Immunol 2021 25;12:637469. Epub 2021 May 25.

Selecta Biosciences, Watertown, MA, United States.

ImmTOR biodegradable nanoparticles encapsulating rapamycin have been shown to induce a durable tolerogenic immune response to co-administered biologics and gene therapy vectors. Prior mechanism of action studies have demonstrated selective biodistribution of ImmTOR to the spleen and liver following intravenous (IV) administration. In the spleen, ImmTOR has been shown to induce tolerogenic dendritic cells and antigen-specific regulatory T cells and inhibit antigen-specific B cell activation. Read More

μSPE followed by HPLC-MS/MS for the determination of series D and E resolvins in biological matrices.

J Pharm Biomed Anal 2021 May 29;203:114181. Epub 2021 May 29.

University of Teramo, Faculty of Bioscience and Technology for Food, Agriculture and Environment, 64100, TE, Italy.

The critical role of acute inflammatory processes is recognized in many chronic diseases; a key point in molecular mechanisms of acute inflammation resolution is represented by a new group of pro-resolving lipid mediators that include distinct families of molecules: lipoxins, resolvins, protectins and maresins, collectively termed "specialized pro-resolving mediators" (SPMs). In particular, resolvins are active in the picogram to nanogram dose range, whereby they can directly modulate a plethora of anti-inflammatory responses. The presented method proposes an analytical protocol able to extract and to quantify 6 different resolvins from 3 different matrices (plasma, cells and exudates). Read More

Structural development of salicylanilide-based SPAK inhibitors as candidate antihypertensive agents.

ChemMedChem 2021 Jun 9. Epub 2021 Jun 9.

JAPAN.

Hypertension is an important target for drug discovery. We have focused on the with-no-lysine kinase (WNK)-oxidative stress-responsive 1 (OSR1) and STE20/SPS1-related proline-alanine-rich protein kinase (SPAK)-NaCl cotransporter (NCC) signal cascade as a potential target, and we previously developed a screening system for inhibitors of WNK-OSR1/SPAK-NCC signaling. Herein we used this system to examine the structure-activity relationship (SAR) of salicylanilide derivatives as SPAK kinase inhibitors. Read More

Low-dose CDK4/6 inhibitors induce presentation of pathway specific MHC ligands as potential targets for cancer immunotherapy.

Oncoimmunology 2021 May 24;10(1):1916243. Epub 2021 May 24.

Molecular Pharmacology Program, Sloan Kettering Institute, New York, USA.

Cyclin dependent kinase 4/6 inhibitors (CDK4/6i) lead to cell-cycle arrest but also trigger T cell-mediated immunity, which might be mediated by changes in human leukocyte antigen (HLA) ligands. We investigated the effects of CDK4/6i, abemaciclib and palbociclib, on the immunopeptidome at nontoxic levels in breast cancer cell lines by biochemical identification of HLA ligands followed by network analyses. This treatment led to upregulation of HLA and revealed hundreds of induced HLA ligands in breast cancer cell lines. Read More

Memory Seeds Enable High Structural Phase Purity in 2D Perovskite Films for High-Efficiency Devices.

Adv Mater 2021 Jun 6:e2007176. Epub 2021 Jun 6.

Department of Chemical and Biomolecular Engineering, Rice University, Houston, TX, 77005, USA.

2D perovskites are a class of halide perovskites offering a pathway for realizing efficient and durable optoelectronic devices. However, the broad chemical phase space and lack of understanding of film formation have led to quasi-2D perovskite films with polydispersity in perovskite layer thicknesses, which have hindered device performance and stability. Here, a simple and scalable approach is reported, termed as the "phase-selective method", to fabricate 2D perovskite thin films with homogenous layer thickness (phase purity). Read More

Uncovering biosynthetic relationships between antifungal nonadrides and octadrides.

Chem Sci 2020 Oct 7;11(42):11570-11578. Epub 2020 Oct 7.

School of Chemistry, University of Bristol Cantock's Close Bristol BS8 1TS UK

Maleidrides are a class of bioactive secondary metabolites unique to filamentous fungi, which contain one or more maleic anhydrides fused to a 7-, 8- or 9- membered carbocycle (named heptadrides, octadrides and nonadrides respectively). Herein structural and biosynthetic studies on the antifungal octadride, zopfiellin, and nonadrides scytalidin, deoxyscytalidin and castaneiolide are described. A combination of genome sequencing, bioinformatic analyses, gene disruptions, biotransformations, isotopic feeding studies, NMR and X-ray crystallography revealed that they share a common biosynthetic pathway, diverging only after the nonadride deoxyscytalidin.
