[No.04-0041] DAPT
Stemolecule DAPT (also known as GSI-IX or LY-374973), a cell-permeable dipeptide, inhibits γ-secretase and indirectly inhibits Notch, a γ-secretase substrate1. Since the Notch pathway is involved in the development of both the nervous system and pancreas, DAPT may be useful in modulating Notch activity in embryonic stem cell differentiation studies2. DAPT has been shown to dose-dependently decrease amyloidβ levels via inhibition of γ-secretase in both plasma and cerebral spinal fluid3. Since amyloid β containing senile plaques are characteristic in Alzheimer’s disease, DAPT may be useful in studies evaluating potential treatments for that disease.

SPECIFICATION
Product Name: Stemolecule DAPT
Catalog Number: 04-0041
Size: 5 mg
Alternate Name(s):
- GSI-IX
- LY-374973
- N-[(3,5-Difluorophenyl)acetyl]-L-alanyl-2-phenylglycine-1,1-dimethylethyl ester
Chemical Formula: C23H26F2N2O4
Molecular Weight: 432.46
CAS Number: 208255-80-5
Purity: Greater than 99% by HPLC analysis
Formulation: White Powder
Solubility: For a 10 mM concentrated stock solution of DAPT, reconstitute the compound by adding 1.16 mL of DMSO to the entire contents of the vial. If precipitate is observed, warm the solution to 37 °C for 2 to 5 minutes. For cell culture, the media should be prewarmed prior to adding the reconstituted compound. Note: for most cells, the maximum tolerance to DMSO is less than 0.5%. This molecule is soluble in DMSO at 100 mM.
Storage and Stability: Store powder at 4 °C protected from light. Information about the stability of Stemolecules in solution is largely not available. As a general guideline, we recommend that stock solution be freshly made and stored in aliquots at −20 °C. The effect of storage of stock solutions should be verified for each application.
Quality Control: The purity of DAPT was determined by HPLC analysis. The accurate mass was determined by mass spectrometry. Cellular toxicity of DAPT was tested on mouse embryonic stem cells.
