| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

LY-900009 is a selective small-molecule inhibitor of γ-secretase with IC50 value of 0.27nM [1].
Notch signaling plays a critical role in stem cell function and is deragulated in different forms of cancer. Γ-secretase cleaves Notch receptor and regulates its signaling. LY-900009 is an oral notch inhibitor for the treatment of cancer but is now terminated in Phase I [2].
The phase I study shows that LY900009 causes adverse events including diarrhea, vomiting, nausea, fatigue, anorexia, hypophosphatemia and rash at different grades. Treatment of 60mg LY900009 shows dose-limiting toxicities of fatigue and diarrhea respectively in 2 patients. The maximum tolerated dose (MTD) of LY900009 is identified at 30mg. And the elimination half-life is about 2-3 hrs. As a γ-secretase inhibitor, LY900009 also decreases plasma levels of amyloid-β in a dose-dependent manner [3].
