|Description||γ-secretase inhibitor and classical notch inhibitor. Induces neuronal differentiation. 3D Growth matrix component and used in cerebral organoid differentiation media.|
|Biological description|| |
DAPT is a γ-secretase inhibitor which blocks notch signaling. It is a classical notch inhibitor.
It has been reported to inhibit amyloid beta (Aβ) in a dose-dependent manner although at low doses, an increase in Aβ production in cell culture and animal models has also been reported.
Uses & applications
DAPT is used in a variety of stem cell applications.
It has been shown that in combination with other small molecules that inhibit SMAD (SB 431542, LDN193189), activate WNT (CHIR99021) and inhibit FGF-signaling (SU5402), DAPT yields 75% post-mitotic neurons in 11 days of differentiation. These are defined as peripheral sensory neurons.
Recently, DAPT in combination with LDN193189, SB431542, XAV939, PD0325901 and SU5402 has been shown to accelerate induction of early-born cortical neurons that have mature electrophysiological properties by day 16 of differentiation.
DAPT also enhances neuronal differentiation in ESC-derived embryoid bodies independent of Hh-signaling.
Additionally, the compound promotes cardiac differentiation of murine pluripotent stem cells and enhances the reprogramming of mouse fibroblasts to iCLMs (induced cardiac-like myocytes).
It is also used as a 3D Growth matrix component and used in cerebral organoid differentiation media.
