Tramiprosate (Alzhemed) is an orally active, blood-brain-barrier-crossing, naturally occurring amino acid found in a variety of red seaweeds that binds soluble Aβ and maintains it in a non-protofibrillar form.It is a GABA analog with neuroprotective, anticonvulsant, and antihypertensive activity.

Hematoxylin (Natural Black 1) is a dye obtained from the heartwood of logwood (Haematoxylon campechianum Linn., Leguminosae) used as a stain in microscopy and in the manufacture of ink.

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.

Avagacestat (BMS-708163) (BMS-708163) is a potent, selective, orally bioavailable γ-secretase inhibitor of Aβ40 and Aβ42 with IC50 of 0.3 nM and 0.27 nM, demonstrating a 193-fold selectivity against Notch. Phase 2.

γ-Secretase modulator 4 is a potent γ-secretase modulator that reduces Aβ42 levels with IC50s of 0.017 μM in mice and 0.014 μM in humans.

Semagacestat (LY450139) (LY450139) is a γ-secretase blocker for Aβ42/Aβ40/Aβ38 (IC50: 10.9/12.1/12.0 nM) and also inhibits Notch signaling (IC50: 14.1 nM).

Aβ42-IN-7 (Compound CT-01) is a brain-penetrant and selective inhibitor of amyloid-β42 (Aβ42). It acts by inhibiting the aggregation of Aβ42 into neurotoxic soluble oligomers and extracellular fibrillar aggregates. Aβ42-IN-7 provides neuroprotection by reducing amyloid protein-mediated neuronal toxicity. This compound is applicable for Alzheimer's disease (AD) research.

Aβ42 agonist-1 is a small molecule compound with anticancer and NF-κB inhibitory activities. It induces Aβ42 aggregation and can be used to study neurological diseases.

DORA 42 is a dual antagonist of the orexin receptor OX1R and OX2R.

KBH-A42 is an inhibitor of histone deacetylase.

GIP (3-42), human (Gastric Inhibitory Polypeptide (3-42) (human)) is a peptide that acts as a glucose-dependent proinsulinotropic polypeptide (GIP) receptor antagonist and regulates insulin secretion and the metabolic effects of GIP in vivo, which can be used to study type 2 diabetes.

HXJ42 is a PP1 analog that selectively and effectively acts on wild-type ZAP-70 (AS).

CES1-IN-42 (2,2-Dimethoxy-2-phenylacetophenone) is a photoinitiator that can be used to assist in cancer research.

Anti-inflammatory agent 42 has anti-inflammatory activity and inhibits the expression of TNF-α and IL-6 in LPS-stimulated macrophages.

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.

Biotin-amyloid-β (1-42) peptide is an affinity probe that allows amyloid-β (1-42) (Aβ42) to be detected or immobilized through interaction with the biotin ligand. It has been used to identify Aβ42 interaction partners in rat hippocampal synaptosomal membranes.
