Osmotic Remodeling of Extracellular Vesicles for Precision Nanomedicine

Small, EarlyView.
Hypotonic lysis in bidistilled water is used to remodel B lymphocyte–derived extracellular vesicles into cargo‐depleted, structurally preserved nanovesicles. The process reduces intraluminal proteins and nucleic acids, reshapes membrane composition, and enhances tumor‐cell uptake in vitro, while allowing proof‐of‐concept reloading with exogenous agents,

Asymmetric Synthesis of Sphinganine and Clavaminol H

, 2016
An efficient enantioselective synthesis of sphinganine and clavaminol H is reported. These sphingoid-type bases were obtained from commercially available fatty acids using highly enantioselective Ru-catalyzed hydrogenation and organocatalytic ...

Natural Algaecide Sphingosines Identified in Hybrid Straw Decomposition Driven by White‐Rot Fungi

Advanced Science, 2023
Harmful algal blooms (HABs), which are promoted by eutrophication and intensified by global warming, occur worldwide. Allelochemicals, which are natural chemicals derived from plants or microbes, are emerging weapons to eliminate these blooms.

Exploring the Cosmeceutical Potential of Six Malaysian Indigenous Tropical Fruit Trees: Radical Scavenging, Anti‐Tyrosinase, and Photoprotective Activities Evaluation

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
B. macrophylla leaf ethyl acetate fractionated extract exhibits the highest TPC, very strong radical‐scavenging activities, and the highest SPF value of 28.64 ± 0.51. LC‐MS analysis identifies m‐trigallic acid, cis‐coutaric acid, and ellagic acid, which may contribute to its bioactivities. The present work highlights B.

Cucumber Mosaic Virus Promotes Sphingolipid Biosynthesis to Alleviate Host Unfolded Protein Response (UPR)‐Mediated Immunity

Molecular Plant Pathology, Volume 27, Issue 9, September 2026.
Sphingolipid levels are elevated in CMV replication site (the tonoplast). Silencing Nb‐TSC10 activates the host salicylic acid–UPR defence axis, indicating CMV promotes sphingolipid biosynthesis to suppress this antiviral pathway. ABSTRACT RNA viruses usually reprogramme host cellular lipid metabolism to create favourable replication microenvironments,

Kinetic characterization of mammalian ceramide synthases: Determination of Km values towards sphinganine [PDF]

, 2007
Ceramide is a key metabolite in the pathway of sphingolipid biosynthesis. In mammals, ceramide is synthesized by N-acylation of a sphingoid long-chain base by a family of ceramide synthases (CerS), each of which displays a high specificity towards acyl ...

Rabbit muscle gangliosides

Journal of Lipid Research, 1972
Four ganglioside fractions were isolated from rabbit muscle : one hematoside and three hexosamine-containing species. They were analyzed for hexoses, hexosamine, sialic acid, fatty acids, and long-chain base content.

Altered Levels of Sphingosine and Sphinganine in Psoriatic Epidermis

Annals of Dermatology, 2013
Background Ceramides are the main lipid component of the stratum corneum and are a structurally heterogeneous and complex group of sphingolipids of which sphingoid bases are the basic structural constituents.
