General description

β-Site amyloid precursor protein (APP) cleaving enzyme-1 (BACE1), an aspartic protease belongs to the protease family of enzymes comprises of six luminal cysteine residues. These residues help in the formation of three intermolecular disulfide bonds and N-linked glycosylation sites.

Application

β-Secretase inhibitor has been used as β-site amyloid precursor protein (APP) cleaving enzyme-1 (BACE1) inhibitor in BACE1 inhibitor assay.(2)
β-Secretase inhibitor may be used to inhibit BACE1 in studies related to AD.

Biochem/physiol Actions

β-Site amyloid precursor protein (APP) cleaving enzyme-1 (BACE1) is a β-secretase that initiates the production of amyloid protein in Alzheimer′s dieases (AD) patients. β-Secretase inhibitors decrease the generation of β amyloid and formation of amyloid plaques typical of AD.

An extensive fluorine scan of 1,3-oxazines revealed the power of fluorine(s) to lower the pKa and thereby dramatically change the pharmacological profile of this class of BACE1 inhibitors. The CF3 substituted oxazine 89, a potent and highly brain penetrant BACE1

Amyloid-β (Aβ) is generated by proteolytic processing of amyloid precursor protein (APP) by beta-secretase (BACE-1) and gamma-secretase. Amyloid-β is responsible for the formation of senile plaques in Alzheimer's disease (AD). Consequently, inhibition of β-secretase (BACE-1), a rate-limiting enzyme in the

Brain-derived neurotrophic factor (BDNF) content and signaling has been identified as one potential regulator of amyloid precursor protein (APP) processing. Recently published work has demonstrated that BDNF reduces BACE1 activity while also elevating the inhibition of GSK3β in the prefrontal

Proteolytic processing of the amyloid precursor protein (APP) generates amyloid beta (Abeta) peptide, which is thought to be causal for the pathology and subsequent cognitive decline in Alzheimer's disease. Cleavage by beta-secretase at the amino terminus of the Abeta peptide
