| 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. |

LY2886721 is an oral and furothiazine-based inhibitor of β site-amyloid protein cleaving enzyme (BACE) with IC50 of 20.3nM. This product has the potency for the treatment of Alzheimer's disease.
BACE, also known as Beta-Secretase 1, is an aspartic-acid protease that plays important role in the formation of myelin sheaths in peripheral nerve cells.
In vitro, treatment of LY2886721 leads to the inhibition of Aβ in HEK293Swe with IC50 of 18.7nM and PDAPP neuronal culture with IC50 10.7 nM1. LY2886721 decreases CSF sAPPβ and increases CSF sAPPα in a dose- dependent manner 2.
In PDAPP mice, oral administration of LY2886721 resulted in a reduction in brain Aβ, C99 and sAPPβ in a dose-dependent pattern 2. Aβ levels in the brain were decreased by 20% -65% as compared with the vehicle-treated groups 3 hours after treatment of LY2886721 at a dosage of 3-30 mg/kg per mice. In addition, LY2886721 significantly lowers plasma and CSF Aβs in the MAD study 1.

The potent BACE1 inhibitor LY2886721 elicits robust central Abeta pharmacodynamic responses in mice, dogs, and humans.[Pubmed:25609634]
J Neurosci. 2015 Jan 21;35(3):1199-210.
BACE1 is a key protease controlling the formation of amyloid beta, a peptide hypothesized to play a significant role in the pathogenesis of Alzheimer's disease (AD). Therefore, the development of potent and selective inhibitors of BACE1 has been a focus of many drug discovery efforts in academia and industry. Herein, we report the nonclinical and early clinical development of LY2886721, a BACE1 active site inhibitor that reached phase 2 clinical trials in AD. LY2886721 has high selectivity against key off-target proteases, which efficiently translates in vitro activity into robust in vivo amyloid beta lowering in nonclinical animal models. Similar potent and persistent amyloid beta lowering was observed in plasma and lumbar CSF when single and multiple doses of LY2886721 were administered to healthy human subjects. Collectively, these data add support for BACE1 inhibition as an effective means of amyloid lowering and as an attractive target for potential disease modification therapy in AD.
