Biochem/physiol Actions

DAPT is a γ-secretase inhibitor and indirectly an inhibitor of Notch, a γ-secretase substrate. Other γ-secretase substrates include LDL receptor-related protein, E-cadherin and ErbB-4. As an inhibitor of γ-secretase, DAPT may be useful in the study of β-amyloid (Aβ) formation. DAPT has been shown to inhibit Notch signaling in studies of autoimmune and lymphoproliferative diseases, such as ALPS and lupus erythematosus (SLE), as well as in cancer cell growth, angiogenesis, and differentiation of human induced pluripotent stem cells (hIPSC).

Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
What isProduct D5942, DAPT soluble in?
DAPT is soluble in DMSO at approximately 18 mg/ml.
Are solutions ofProduct D5942, DAPT stable?
Sigma has not evaluated the solution stability of DAPT. However, in a study of cultured insect cells, DAPT inhibited γ-secretase activity for 12 hours, which is indicative of its stability in solution at a presumed 37 °C temperature. Pitsi, D., and Octave, J.N., Presenilin 1 stabilizes the C-terminal fragment of the amyloid precursor protein independently of γ-secretase activity. J. Biol. Chem., 279(24), 25333-25338 (2004).
IsProduct D5942, DAPT, a reversible or irreversible inhibitor of beta secretase?
The literature indicates that in a treatment of PDAPP neuronal cultures with DAPT, removal of DAPT from the protocol restores amyloid precursor protein β production. This implies that DAPT may be a reversible inhibitor. Dovey, H.F., et al. Functional gamma-secretase inhibitors reduce beta-amyloid peptide levels in brain. J. Neurochem., 76(1), 173-181 (2001).
