Description
GW4869 (GW69A) is a selective and non-competitive inhibitor of neutral sphingomyelinase N-SMase (IC50=1 μM). GW4869 also inhibits exosome synthesis/release and is commonly used in exosome-related studies.Usually prepared as a suspension for experiments.

In vitro
METHODS: Human breast cancer cells MCF-7 were pretreated with GW4869 (10 μM) for 30 min, then incubated with TNF (3 nM) for 6-24 h. Ceramide levels were detected by E. coli diacylglycerol kinase assay.
RESULTS: GW4869 significantly inhibited TNF-induced ceramide accumulation, and GW4869 inhibited N-SMase. [1]
METHODS: Macrophage RAW264.7 was pretreated with GW4869 (10-20 μM) for 2 h, and then incubated with LPS (1 μg/mL) for 24 h. AchE activity was measured.
RESULTS: After pretreatment of macrophages with 10 μM GW4869, LPS-triggered exocytosis was significantly attenuated in macrophages, and the activity of AChE was reduced by 22%. Treatment with 20 μM GW4869 further enhanced this attenuation. [2]
In vivo
METHODS: To detect in vivo activity, GW4869 (2.5 μg/g) was injected intraperitoneally into C57BL/6 mice, and LPS (25 μg/g) was injected 1 h later.
RESULTS: Pretreatment of mice with GW4869 attenuated LPS-triggered production of exosomes and pro-inflammatory cytokines in the blood, thereby reducing myocardial inflammation. [2]
METHODS: To assay in vivo activity, GW4869 (200 μL of 0.3 mg/mL, 2-2.5 μg/g) was administered intraperitoneally to 5XFAD mice every two days for six weeks.
RESULTS: GW4869 reduced amyloid plaque formation in vivo by blocking exosome secretion. [3]
Kinase Assay
B. cereu sphosphatidylcholine-PLC is incubated in the presence or absence of 10 μM GW4869 in a reaction mixture containing 100 mM Tris, pH 7.2, 25% glycerol, 20 mM p-nitrophenyl/phosphorylcholine, and production of p-nitrophenol is quantified spectrophotometrically at 410 nm. Protein phosphatase 2A from bovine kidney is incubated in the presence or absence of GW4869 in buffer containing 50 mM Tris, pH 7.4, 1 mM dithiothreitol, 100 μM MnCl2, and 20% glycerol, and phosphatase activity is measured[1].
Cell Research
GW4869 is routinely stored at ?80?°C as a 1.5 mM stock suspension in Me2SO. Right before use, the suspension is solubilized by the addition of 5% methane sulfonic acid (MSA) (2.5 μl of 5% MSA in sterile double-distilled Water are added to 50 μL of GW4869 stock suspension). Cells are treated with GW4869 for 30 min and then TNF is added in 10 μL/well. At the indicated time points, 25 μL of MTT stock solution are added to each well and incubated at 37?°C in 5% CO2 for 3 h. The cell viability is using the MTT assay[1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
