γ-Secretase is a multi-subunit enzyme complex that catalyzes the cleavage of various transmembrane proteins, including amyloid precursor protein (APP) and Notch. Processing of APP by γ-secretase leads to the production of amyloid-β peptides, which aggregate to form the amyloid plaques that are a hallmark of Alzheimer’s disease. Cleavage of Notch, on the other hand, triggers gene transcription and downstream signaling essential for cell–cell communication, particularly in processes such as embryonic development, cell differentiation, endocrine system formation, and potentially tumorigenesis. Notch activity supports cell survival while inhibiting apoptosis.

Inhibiting γ-secretase and the Notch pathway can reduce amyloid-β production and slow or stop cell proliferation, especially in stem cells. Targeting Notch signaling may also specifically affect cancer stem cells, inducing differentiation or apoptosis. Because Notch signaling intersects with numerous other pathways—including PI3K/Akt, Ras, NF-κB, EGFR, and VEGFR—inhibition impacts these downstream systems as well.

Aladdin offers several γ-secretase inhibitors with applications across multiple research fields. In Alzheimer’s disease models, LY-450139 (S125519) blocks the formation of new amyloid plaques. MK-0752 (M126008) has shown potential in targeting brain and CNS-related cancers. FLI-06 (F275654) inhibits protein secretion prior to exit from the endoplasmic reticulum, demonstrating neuroprotective effects. Available inhibitors are listed in the below sheet.

Aladdin Scientific provides a rich suite of γ-secretase-targeting reagents with diverse mechanisms—ranging from potent inhibitors to modulators—high product quality, thoughtful packaging, global access, and strong brand reliability. This combination makes them a top choice for labs performing Alzheimer’s disease, Notch signaling, or general mechanistic neurobiology research.
