In vitro
DAPT, (N-{N-[2-(3,5-Difluorophenyl)acetyl]-(S)-alanyl}-(S)-phenylglycine tert-butyl ester), is a inhibitor of gamma-secretase( IC50=20 nM), which is involved in Alzheimers disease. DAPT also can inhibit cdk5. Its interesting that DAPT attenuated activity of CDK5, but DAPT can up-regulate the level of CDK5. DAPT can disrupt cdk5 and p35 interaction. DAPT up-regulated neurogenin that is negatively regulated by Notch, and down-regulated Hes1, a downstream target of Notch.
In vivo
Neurons treated with 10 microM DAPT showed attenuated cdk5 activity in spite of an up-regulation of cdk5 protein level, consistent with a phenomenon reported in the cdk5 transgenic mice. In U87MG xenograft mouse models, DAPT treatment increased tumor vessel density but compromised vessel function, as evidenced by poor perfusion and aggravated hypoxia.
