Aβ-IN-1 is a novel, potent and orally active γ-secretase modulator (GSM). Aβ-IN-1 potently reduced Aβ42 levels with an IC 50 value of 0.091 μM in cultured cells without inhibiting CYP3A4. Aβ-IN-1 shows a sustained pharmacokinetic profile.

Aβ42-IN-2, a γ-secretase modulator with an IC50 of 6.5 nM for Αβ42, can be used for Alzheimer's disease research [1].

Crenigacestat (LY3039478) is an orally bioavailable Notch inhibitor with an IC50 of ~1 nM in most tumor cell lines tested. It effectively inhibits mutant Notch receptor activity and, in a xenograft tumor model, inhibits the expression of Notch-regulated genes and N1ICD cleavage in the tumor microenvironment.

3,5-Bis(4-nitrophenoxy)benzoic acid (Compound W) is a γ-secretase inhibitor that reduces the levels of released Aβ42 and notch-1 Aβ-like peptide 25 (Nβ25).

Aftin-4, an amyloid forty-two inducer, activates γ-secretase, promoting the generation of amyloid-β-1-42 (Aβ1-42) from amyloid-β protein precursor. Aftin-4(Aftin4) increased Aβ-1-42, but not Aβ-1-40 in mouse hipppocampus, accompanied by learning deficits and mitochondrial ultrastructural changes similar to those found in the brains of patients with AD. Aftin-4(Aftin4) can thus be used to induce a rapid, acute Alzheimer's disease-like toxicity in the rodent brain.

Aβ42-IN-1, compound 1v, is a novel, potent and orally active γ-secretase modulator (GSM). Aβ42-IN-1 potently reduced Aβ42 levels with an IC 50 value of 0.091 μM in cultured cells without inhibiting CYP3A4. Aβ42-IN-1 shows a sustained pharmacokinetic profile.

Aβ42-IN-1 free base (compound 1v), an orally active γ-secretase modulator with high brain exposure, effectively lowers Aβ42 levels with an IC50 of 0.091 μM, and significantly diminishes brain Aβ42 levels in mice. Given these properties, Aβ42-IN-1 free base represents a potential disease-modifying agent for Alzheimer's disease [1].

BPN-15606, an orally active γ-secretase modulator (GSM), significantly reduces Aβ42 and Aβ40 production in SHSY5Y neuroblastoma cells, demonstrating IC50 values of 7 nM and 17 nM, respectively. This compound exhibits favorable pharmacokinetic pharmacodynamic (PK PD) properties, such as bioavailability, half-life, and clearance. Importantly, BPN-15606 markedly decreases Aβ42 and Aβ40 levels in the central nervous system of both rats and mice[1].

Dihydroergocristine mesylate (DHEC (mesylate))(DHEC mesylate) is the methanesulfonic acid salt of dihydroergocristine. It has been used as the for the symptomatic treatment of mental deterioration associated with cerebrovascular insufficiency and in peripheral vascular disease. Dihydroergocristine mesylate is a inhibitor of γ-secretase (GSI), , reduces the production of the Alzheimer's disease amyloid-β peptides, binds directly to γ-secretase and Nicastrin with equilibrium dissociation constants (Kd) of 25.7 nM and 9.8 μM, respectively[1]. It is also a component of ergoloid mesylate (codergocrine mesilate), a mixture of ergot alkaloid derivatives that is used as a vasodilator and has shown mild benefits in the treatment of vascular dementia. It has a role as a vasodilator agent, an alpha-adrenergic antagonist and a geroprotector. It contains a dihydroergocristine.

Gamma-secretase modulator 2 is a potent, selective compound for the treatment of Alzheimer's disease, specifically designed to modulate γ-secretase activity. This modulation selectively attenuates the production of Aβ(1-42), addressing diseases associated with Aβ deposition in the brain, particularly Alzheimer's disease.

γ-Secretase modulator 12 (Compound 1a) is a selective compound that effectively reduces amyloid-β42 (Aβ42) levels with an IC50 of 0.39 μM, specifically designed for Alzheimer's disease research. Notably, γ-Secretase modulator 12 exhibits a favorable brain plasma ratio (Kp, brain = 0.72) in mice [1].

Amyloid 17-42 (Aβ(17-42)), a significant component of diffuse plaques in Alzheimer's disease and cerebellar pre-amyloid in Down's syndrome, results from alpha- and gamma-secretase cleavage of amyloid precursor protein (APP) and can trigger neuronal apoptosis via the Fas-like caspase-8 activation pathway [1].

Fosciclopirox disodium suppresses urothelial cancer growth by targeting the γ-secretase complex and selectively delivering the active metabolite, Ciclopirox, throughout the urinary tract. Ciclopirox demonstrates anticancer activity in various solid and hematologic malignancies [1] [2].

γ-Secretase Modulator 14, a γ-secretase modulator, shows potential for use in Alzheimer's disease (AD) research (WO2013010904A1; compound 42) [1].

SSZ is a multitarget inhibitor that addresses various pathological mechanisms in Alzheimers disease (AD). It targets acetylcholinesterase (acetylcholinesterase), butyrylcholinesterase (butyrylcholinesterase), β-site amyloid precursor protein-cleaving enzyme 1 (BACE1), and γ-secretase (γ-secretase). In murine models, SSZ has been shown to improve Alzheimers disease and exhibit neuroprotective effects.

Sulindac EP Impurity C-d3 is a deuterated compound of Sulindac EP Impurity C. Sulindac EP Impurity C has a CAS number of 32004-67-4. (E Z)-Sulindac sulfide is a potent γ-secretase modulator (GSM) that selectively reduces Aβ42 production in favor of shorter Aβ species. (E Z)-Sulindac sulfide can be used for researching Alzheimer's disease [1].
