Soluble Gamma-secretase Modulators Attenuate Alzheimer's β-amyloid Pathology and Induce Conformational Changes in Presenilin 1
A central pathogenic event of Alzheimer's disease (AD) is the accumulation of the Aβ42 peptide, which is generated from amyloid-β precursor protein (APP) via cleavages by β- and γ-secretase. We have developed a class of soluble 2-aminothiazole γ-secretase modulators (SGSMs) that preferentially decreases Aβ42 levels. However, the effects of SGSMs in AD animals and cells expressing familial AD mu...
متن کاملNatural Product and Natural Product-Derived Gamma Secretase Modulators from Actaea Racemosa Extracts
Alzheimer's disease is characterized by pathogenic oligomerization, aggregation, and deposition of amyloid beta peptide (Aβ), resulting in severe neuronal toxicity and associated cognitive dysfunction. In particular, increases in the absolute or relative level of the major long form of Aβ, Aβ42, are associated with increased cellular toxicity and rapidity of disease progression. As a result of ...
متن کاملSubstrate docking to γ-secretase allows access of γ-secretase modulators to an allosteric site
γ-Secretase generates the peptides of Alzheimer's disease, Aβ(40) and Aβ(42), by cleaving the amyloid precursor protein within its transmembrane domain. γ-Secretase also cleaves numerous other substrates, raising concerns about γ-secretase inhibitor off-target effects. Another important class of drugs, γ-secretase modulators, alter the cleavage site of γ-secretase on amyloid precursor protein, ...
متن کاملTarget of γ-secretase modulators, presenilin marks the spot.
c-Secretase modulators, or GSMs, which reduce the production of Ab42, have emerged as a promising class of compounds for the treatment of Alzheimer’s disease (AD). The target and mechanism of action of GSMs have been controversial as of late, with some evidence suggesting that GSMs function by binding the substrate, amyloid precursor protein (APP), and others claiming action through direct modu...
متن کاملGamma secretase inhibitors of Notch signaling
The numerous processes involved in the etiology of breast cancer such as cell survival, metabolism, proliferation, differentiation, and angiogenesis are currently being elucidated. However, underlying mechanisms that drive breast cancer progression and drug resistance are still poorly understood. As we discuss here in detail, the Notch signaling pathway is an important regulatory component of n...
