β amyloid (42 1), human

β-Amyloid (42-1), human is the inactive form of amyloid β peptide (1-42), consisting of 42 amino acids. It plays a key role in the pathogenesis of Alzheimer's disease and is commonly used to induce Alzheimer's disease models.

β-Amyloid (1-42), human, Ala(13C3,15N) TFA is a β-Amyloid (1-42), human marked with 13C and 15N. This unprocessed HFIP peptide comprises 42 amino acids and is a brain-permeable amyloid fragment, useful for researching Alzheimer's and Down syndrome. In monomer form, β-Amyloid (1-42), human provides antioxidant and neuroprotective effects. Upon HFIP monomerization and DMSO solvent preparation, it forms soluble oligomers (AβOs) at 4°C, which exhibit synaptotoxicity and neurotoxicity, while at 37°C it forms insoluble fibrils with lower neurotoxicity, involved in oxidative damage. Aβ42 oligomers interact with neuronal surface receptors such as PrPc, mGluR5, and NMDA receptor, activating signaling pathways that induce oxidative stress, calcium imbalance, synaptotoxicity, leading to neuronal dysfunction and death.

AChE/MAO-B-IN-3 is a dual inhibitor targeting both acetylcholinesterase (AChE) and monoamine oxidase B (MAO-B), exhibiting inhibitory concentrations (IC50s) of 0.0257 μM and 0.0456 μM against human AChE and MAO-B, respectively. This compound holds potential for Alzheimer's disease research.

AChE/MAO-IN-1 is a potent inhibitor of human acetylcholinesterase (AChE), monoamine oxidase A (MAO-A), and monoamine oxidase B (MAO-B), demonstrating inhibitory concentrations (IC50) of 0.0248 μM, 0.0409 μM, and 0.1108 μM against AChE, MAO-A, and MAO-B, respectively.

β-Amyloid (1-43)(human) TFA exhibits greater aggregation tendencies and heightened toxicity compared to Aβ1-42. This compound also associates with sAPPα and sAPPβ and has the potential to serve as an additional biomarker for Alzheimer's disease (AD), complementing existing markers [1].

PD07 is an orally active acetylcholinesterase (AChE) inhibitor, exhibiting an IC50 of 0.29 μM against human AChE, and demonstrates inhibition of cholinesterases (ChEs), β-site amyloid precursor protein cleaving enzyme 1 (BACE1) with an IC50 of 13.42 μM, as well as Aβ1–42 aggregation in vitro. Additionally, PD07 possesses antioxidant properties with a DPPH radical inhibition IC50 value of 26.46 μM and has been shown to ameliorate memory and cognitive deficits in scopolamine-induced amnesic rats. This compound is relevant for Alzheimer's disease research [1].
