QUICK LINKS

GW4869 (dihydrochloride hydrate) is a cell permeable, selective inhibitor of N-SMase (neutral sphingomyelinase). It functions as an inhibitor via a non-competitve manner. N-SMases are important in the metabolism of sphingomyelin producing ceramide and phosphocholine, which are important in cell signaling and regulation. Studies indicate that GW4869 can inhibit the activation of N-SMase by TNF-alpha in MC7 cells. As a result of this, cell death and growth suppression are inhibited. Although GW4869 does not effect polymorphonuclear neutrophil (PMN) motility, it is useful with formylmethionylleucylphenylanaline (FMLP), since it inhibits PMN aggregation towards the chemotaxin.

How long can I store this in DMSO solution?

Asked by: SCM4
A stock solution can be made by dissolving the GW4869 in an organic solvent purged with an inert gas. (GW4869 is soluble in DMSO at approximately 0.2mg/ml.) We recommend the DMSO be purged with an inert gas and to cap it with inert gas. The stock solution should be stored at 4º C, but we do have information as to how long it can be stored in this manner. If aqueous stock solutions are required for biological experiments they are best prepared the day of by diluting the organic solvent into aqueous buffers or isotonic saline. We recommend ensuring that the residual amount of organic solvent is insignificant because even at very low concentrations some organic solvents may have unintended effects on the experiment.

Rated 1 out of 5 by from Likely contaminated with impuritiesI purchased this reagent several months ago with the intent on validating and using GW4869 to decrease global vesicle secretion from a variety of cells. In fact, after months of costly experiments, we have a multitude of data suggesting vesicle secretion was increased in the presence of this drug, likely due to contamination of the stock reagent. Highly recommend against using this reagent which may have confounding impurities, and instead ordering from a separate company. We have independently confirmed expected vesicle release from our cells using a similar reagent from a different supplier.
