D-threo-PDMP
Based on 1 Customer Validation
D-threo-PDMP is a potent glucoceramide synthase (GCS) inhibitor, which reduces the glycosphingolipids (such as GM3 and GD3) on the cell surface by inhibiting glycosylation, reduces the total length of the axon plexus and the number of axon branch points, and inhibits neurite growth. D-threo-PDMP inhibits the synthesis of GM3, thereby reducing the adhesion ability of B16 melanoma cells and mimicking the pathological effects of hyperglycemia/TGF-β1. D-threo-PDMP inhibits the synthesis of GD3, thereby protecting liver cells from apoptosis induced by TNF-α. D-threo-PDMP can be used to study diseases related to targeted glycosphingolipid metabolism.

Biological Activity
D-threo-PDMP (2-14 h) inhibits the synthesis of glycosphingolipids and enhances the accumulation of ceramides, and protects hepatocytes from death induced by TNF-α[1].
D-threo-PDMP (20 μM, 24 h) significantly stimulates the proliferation of tethered glomerular mesangial cells (GMC) and also inhibit the synthesis enzyme of ganglioside, specifically reducing the level of GM3[2].
D-threo-PDMP (5-20 μM, 2 d) dose-dependently inhibits the neurite growth of rat explants[3].
D-threo-PDMP (5-40 μM, 8 d) significantly reduces the frequency of synchronous Ca2+ oscillations in cortical neurons[3].
D-threo-PDMP (10-15 μM, 20 h) inhibits the adhesion of B16 melanoma cells by blocking glycolipid synthesis[4].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 5 mg/mL (12.80 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 5 mg/mL (12.80 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
