Galactosylceramide (GalC) is a galactosylceramide that has been implicated in many physiological and pathological phenomena. For example, important lysosomal storage disorders such as Gaucher disease (GD) and neurodegenerative diseases are characterized by GlcCer accumulation.

N,N-Dimethylsphingosine is a sphingosine kinase inhibitor. N,N-Dimethylsphingosine binds competitively to sphingosine kinase and blocks the conversion of sphingosine to sphingosine-1-phosphate. N,N-Dimethylsphingosine inhibits sphingosine-1-phosphate release and aggregation of platelets, and also exerts pro-apoptotic effects by resetting ceramide/sphingosine-1-phosphate homeostasis. N,N-Dimethylsphingosine can be used in cancer-related research.

Sphingosylphosphorylcholine is a bioactive lipid and a major component of plasma high-density lipoprotein that binds to OGR1 with a K_d of 33.3 nM. Sphingosylphosphorylcholine triggers delayed phosphorylation of Smad2, upregulates α-SMA expression, and activates TRPM3. Sphingosylphosphorylcholine reduces Apoptosis and upregulates the expression of uPA and its receptor uPA-R. Sphingosylphosphorylcholine exerts anti-apoptotic, anti-cardiac hypertrophy and pro-wound healing effects. Sphingosylphosphorylcholine induces scratching behavior in mice. Sphingosylphosphorylcholine is used in studies related to atopic dermatitis, promyelocytic leukemia, heart failure, myocardial ischemia/reperfusion injury, ovarian cancer, breast cancer, pancreatic cancer, and skin wound healing disorders in genetically impaired healing diabetes.

Sphinganine 1-phosphate (D-erythro-Dihydrosphingosine 1-phosphate) is a polar sphingolipid metabolite that regulates cell migration, differentiation, survival and complex physiological processes.

C24-Ceramide (d18:1/24:0) is a sphingolipid that can be used for the lipid membranes composed. C24-Ceramide (d18:1/24:0) induces time-dependent changes in membrane properties. C24-Ceramide (d18:1/24:0) induces membrane reorganization.

Ganglioside GM2 is a human tumor antigen predominantly found in human tumor cells and fetal brain tissue. As a sialylated glycosphingolipid, Ganglioside GM2 is involved in processes such as cell signaling, adhesion, and motility. Ganglioside GM2 abnormal expression and accumulation are associated with tumors and neurodegenerative disorders. Ganglioside GM2 promotes tumor cell migration and invasion by directly binding to the integrin β1 receptor, activating the FAK/Src/Erk-MAPK signaling pathway, and inducing actin cytoskeleton remodeling.

C6 NBD Glucosylceramide is a glucosylceramide fluorescent derivative (Ex=466 nm, Em=535 nm). C6 NBD Glucosylceramide can be used to study the metabolism and internalization of glucosylceramide and also for the determination of glucosyl ceramide synthase activity.

The Golgi apparatus is composed of flattened vesicles superimposed on each other by unit membranes. The flattened vesicles are round with expanded and perforated edges. The Golgi fluorescent probe is a BODIPY-labeled ceramide derivative, the synthesis of which occurs in the endoplasmic reticulum and can then be transported to the Golgi via ceramide transport protein (CERT) or vesicular translocation, allowing specific labeling of the dye. BODIPY TR Ceramide (Golgi-Red Tracke) is a Golgi-specific fluorescent dye, which can visualise individual cells. Ex/Em=589 nm/616 nm.

GlcCer (d18:1/18:0) (C18 Glucosyl(β) ceramide (d18:1/18:0)) is a glycosphingolipids that activates the Wnt/β-catenin pathway by targeting LRP6. GlcCer (d18:1/18:0) drives EMT, migration, invasion and GBA1-mediated liver cancer metastasis. GlcCer (d18:1/18:0) accumulates to impair lysosomal function and induce toxic α-synuclein aggregation.
