Abstract

Objective: To explore the in vitro anti-inflammatory activity and action mechanism of a polysaccharide extracted from Polygonum divaricatum L. (PSPDL). Methods: The structure of PSPDL was characterized using high-performance gel permeation chromatography (HPGPC), high-performance liquid chromatography (HPLC), Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and nuclear magnetic resonance spectroscopy (NMR). The in vitro anti-inflammatory activity and action mechanism of PSPDL were investigated in lipopolysaccharide (LPS)-induced RAW264.7 cells. Results: PSPDL had a relative molecular mass of 59.475 kDa and consisted mainly of mannose (Man), rhamnose (Rha), glucuronic acid (GlcA), galacturonic acid (GalA), glucose (Glc), galactose (Gal), and arabinose (Ara), with a molar ratio of 1.69:4.95:1.04:21.79:19.01:31.68:19.84. PSPDL was an α-pyran polysaccharide containing (1→4)-α-D-Glcp linkage. PSPDL inhibited the release of inflammatory factors and related gene mRNA expression, ameliorated oxidative stress, down-regulated the protein expression levels of p38, p-p38, IκB-α, p65, and p-p65. Conclusion: PSPDL exhibited anti-inflammatory activity, perhaps by regulating inflammatory mRNA expression and modulating the mitogen-activated protein kinases/nuclear factor kappa B (MAPK/NF-κB) signaling pathway. This finding provides a scientific basis for the development and utilization of PSPDL resources.

Abstract

Layered Delafossite-type Lix(M1M2M3M4M5…Mn)O2 materials, a new class of high-entropy oxides, were synthesized by nebulized spray pyrolysis and subsequent high-temperature annealing. Various metal species (M = Ni, Co, Mn, Al, Fe, Zn, Cr, Ti, Zr, Cu) could be incorporated into this structure type, and in most cases, single-phase oxides were obtained. Delafossite structures are well known and the related materials are used in different fields of application, especially in electrochemical energy storage (e.g., LiNixCoyMnzO2 [NCM]). The transfer of the high-entropy concept to this type of materials and the successful structural replication enabled the preparation of novel compounds with unprecedented properties. Here, we report on the characterization of a series of Delafossite-type high-entropy oxides by means of TEM, SEM, XPS, ICP-OES, Mössbauer spectroscopy, XRD including Rietveld refinement analysis, SAED and STEM mapping and discuss about the role of entropy stabilization. Our experimental data indicate the formation of uniform solid-solution structures with some Li/M mixing.
