Inhibitor of γ-secretase; causes a reduction in Aβ40 and Aβ42 levels in human primary neuronal cultures (IC50 values are 115 and 200 nM for total Aβ and Aβ42 respectively) and in brain extract, cerebrospinal fluid and plasma in vivo. Does not affect APPα and APPβ levels. Blocks Notch signaling in hybrid human-mouse fetal thymus organ culture (FTOC). Activity causes ESCs to commit to neuronal differentiation.

I used this product for differentiation of iPSCs into dopaminergic neurons according to the protocol published in Kriks et al, 2011.I used the concentration 10uM and it works really well.

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, affecting approximately 47 million people worldwide. Updated in 2015, this poster summarizes the structural and functional changes observed in the progression of this neurodegenerative disease, as well as classic AD drug targets.
