C2 Ceramide is a short-chain cell-permeable ceramide analogue that inhibits the protein Bcl2 phosphorylation with an IC50 value of 14μmol/L [1]. C2 Ceramide serves as an effective research tool for tumor cell apoptosis studies because C2 Ceramide can activate apoptosis in nearly all cell types[2].
In vitro, C2 Ceramide exhibited the IC50 value of 39µmol/L toward HEp-2 cells for 24h[3]. C2 Ceramide caused the inhibition of HERG potassium channel current in HEK293 cells with an IC50 value of 19.5μmol/L after 10h treatment[4]. C2 Ceramide (25μmol/L, 1h) inhibited the mRNA levels and promoter activities of MMP-1, MMP-3 and MMP-9 in U87MG glioma cells, and suppressed cell migration[5]. The application of C2 Ceramide at a concentration of 50μmol/L for 60 minutes blocked the production of reactive oxygen species triggered by hydrogen peroxide and prevented the resulting cell death in rat primary astrocytes[6].
In vivo, C2 Ceramide treatment at 2.0mg/kg by intraperitoneal injection with Long Evans rat pups for 25 days alleviated the symptoms of hyperglycemia, hyperlipidemia and mild steatohepatitis, reduced the lipid content in the brain, and increased the ceramide levels in the liver, brain and serum[7]. The administration of 120μmol/L C2 Ceramide by gavage for 12 hours resulted in a significant reduction of mRNA and protein expression levels of HNF-1 and GSTA1 in the liver of adult male Kunming mice with acetaminophen-induced acute liver injury[8].

Cell lines | HN4 and HN30 cell lines |
Preparation Method | The HN4 and HN30 cell lines were seeded at a density of 1×104 cells per well into 96-well plates with each well containing 100μL of medium. Cells received treatment with C2 Ceramide at concentrations of 0, 20, 40, and 60μmol/L and combinations of C2 Ceramide with autophagy inhibitor CQ at 5μmol/L, necroptosis inhibitor Nec-1 at 5μmol/L, or MEK inhibitor PD98059 at 10μmol/L for 24 hours starting from 24 hours after cell seeding. A minimum of five wells served as replicates for each experimental group. Following the incubation period, 10μL of CCK-8 reagent from a Cell Counting Kit-8 was added to each well, and cells continued to grow in culture. The microplate reader recorded absorbance at 450nm after adding the CCK-8 reagent for 3 hours. All cells were divided into two groups: a DMSO-treated group and a C2 Ceramide-treated group. The cells underwent treatment for 24 hours before collection. Extract fragmented DNA using DNAiso Reagent following the manufacturer's instructions before performing electrophoresis on 2g/L agarose gels containing 0.5g/L ethidium bromide and visualizing the results with UV transillumination. All experiments were repeated three times. |
Reaction Conditions | 0, 20, 40, and 60μmol/L; 24h |
Applications | C2 Ceramide exhibited concentration-dependent cytotoxicity in HN4 and HN30 cell lines. C2 Ceramide induced both caspase-3-independent apoptosis and necroptosis. |
Animal experiment [2]: | |
Animal models | C57BL/6 mice |
Preparation Method | The 25 C57BL/6 mice were assigned randomly to five groups which included a control group, a model group, and C2 Ceramide low-, medium-, and high-dose groups each containing five mice. The control group remained untreated, and the mouse model of Parkinson’s disease was generated through the injection of mutant A53T α-Syn oligomers into the left striatum of all other groups. The three C2 Ceramide groups received a single intragastric dose of C2 Ceramide at concentrations of 1, 5, and 10μg/g dissolved in saline on the 30th day after injection into the striatum while control and model groups received the same saline volume between days 30 to 90 for 60 days total. Monitor behavioral changes in the mice across all groups. The mouse brain tissue samples were collected by perfusion while the mice remained under anesthesia on the 90th day post striatal injection before examining dopaminergic neuron changes in the midbrain substantia nigra through immunohistochemical staining. ELISA tests showed α-Syn oligomerization and phosphorylation levels in the mouse midbrain while enzyme activities linked to α-Syn phosphorylation underwent analysis. |
Dosage form | 1, 5, and 10μg/g for 60 days; i.g. |
Applications | C2 Ceramide (10μg/g) treatment significantly reduced the content of α-Syn oligomers and phosphorylated α-Syn, increased the content of ceramide, and up-regulated the activity of protein phosphatase 2A in the brain tissue of mice. |
