Targeting sphingosine kinase 2 (SphK2) has become a novel strategy for the treatment of cancer. However, potent and selective SphK2 inhibitors are rare. In our work, a series of novel SphK2 inhibitors were innovatively designed, synthesized and screened. Compound 12e showed the best inhibitory activity. Molecular dynamics simulations were carried out to analyze the detailed interactions between the SphK2 and its inhibitors. Moreover, 12e exhibited anti-proliferative activity in various cancer cells, and inhibited the migration of human breast cancer cells MCF-7.

This study focuses on the stereoselective syntheses of 1-deoxysphingosine analogues as potential inhibitors of sphingosine kinase (SphK), particularly targeting its isoforms SphK1 and SphK2, which are implicated in cancer progression and therapy resistance. The research builds on previous work by designing a series of analogues featuring systematic structural modifications like the incorporation of a triazole ring, varying degrees of fluorination, and different head groups (, guanidino, -methylamino, and ,-dimethylamino). These modifications aimed to enhance polar and hydrophobic interactions especially with SphK2.

Objective: Synovial inflammation is vital for the progression of osteoarthritis (OA). The objective of this study was to explore the effects and potential molecular mechanisms of sphingosine kinase 2 (SPHK2) on the proliferation and migration of fibroblast-like synoviocytes (FLS).
Methods: A TNF-α-stimulated FLS model and a papain-induced OA rat model were constructed.

Sphingosine-1-phosphate (S1P) is a ubiquitous lipid mediator, acting via specific G-protein-coupled receptors (GPCR) and intracellularly. Previous work has shown that deletion of S1P lyase caused a chronic elevation of cytosolic [Ca] and enhanced Ca storage in mouse embryonic fibroblasts. Here, we studied the role of sphingosine kinase (SphK)-1 in Ca signaling, using two independently generated EA.

Background: Epithelial-to-mesenchymal transition (EMT), cancer stem cells (CSCs), and colorectal cancer (CRC) therapy resistance are closely associated. Prior reports have demonstrated that sphingosine-1-phosphate (S1P) supports stem cells and maintains the CSC phenotype. We hypothesized that the EMT inducer SNAI1 drives S1P signaling to amplify CSC self-renewal capacity and chemoresistance.
