Description

Application

DAPT has been used: as acomponent in neuronal differentiation medium (NDM) to initiate cortical neuronpatterning[1], as a Notch signaling inhibitor to study its effects on hair cellregeneration in zebrafish[2], as a γ-secretase inhibitor to block the Notchpathway to evaluate its effects on rat pulmonary artery smooth muscle cells(PASMC) proliferation[3]

Biochem/physiol Actions

γ-secretase inhibitor, blocks Notch signaling.

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).
