Synthesis of ceramides using N-hydroxysuccinimide esters
Fatty acyl esters of N-hYdroxYSuccinimide have been used to directly N-acylate sphingenine or sphinganine, forming the corresponding ceramides. The reaction proceeds in excellent yield (84–96%) from small amounts of starting material (10–20 mg).

Abstract This research describes the engineering of chitosan nanoparticles (CS NPs) via ionic gelation to encapsulate Ajwah seed extract (ASE), repurposing a plant waste product for its documented antioxidant and anticancer potential. Physicochemical analysis confirmed the formation of stable nanoparticles with hydrodynamic diameters between 152.3 and ...

Gas-liquid chromatography-mass spectrometry of synthetic ceramides containing phytosphingosine
Ceramides containing phytosphingosine as base and one of the fatty acids 16:0, 18:0, 20:0, 22:0, 23:0, and 24:0, were prepared by direct coupling in the presence of a mixed carbodiimide. The ceramides were analyzed as the 1,3,4-tri-O-trimethylsilyl ether

Optical manipulation of sphingolipid biosynthesis using photoswitchable ceramides
Ceramides are central intermediates of sphingolipid metabolism that also function as potent messengers in stress signaling and apoptosis. Progress in understanding how ceramides execute their biological roles is hampered by a lack of methods to ...

In this review, agents such baicalein, troxerutin, epigallocatechin gallate, quercetin, melatonin, valproic acid, lithium, neurosteroid progesterone, as well as minocycline have been implicated as neuroprotective agents for irradiation‐induced neurological deficits. Also, agents such as glucocorticoids, methylphenidate, vitamin E, bisdemethoxycurcumin,

First use of a natural swine model with lipid metabolism to directly link lipid differences to a quantifiable intestinal villus height phenotype. Identified the phospholipid‐derived oleoylethanolamide, rather than canonical fatty acids, as the endogenous primary ligand that activates peroxisome proliferator‐activated receptors α (PPARα) to enlarge ...

Our study employed an integrated lipidomics and metabolomics approach to elucidate Helicobacter pylori‐driven metabolic perturbations along the gut–brain axis. H. pylori infection was established in gastric epithelial (AGS) cells, and the resulting conditioned media (secretome) was collected and exposed to neuronal (IMR‐32) cells.

Comprehensive understanding of how diverse PGPR strains enhance the rhizosphere microenvironment remains a considerable challenge. Here, we provide experimental evidence that a functionally synergistic composite microbial formulation can markedly enhance growth performance and improve the quality attributes in Angelica sinensis.
