Homogentisic acid	Structural Classification Other disease Classification of Application Fields Ketones, Aldehydes, Acids Disease markers Phenols Polyphenols Metabolic Disease Endogenous metabolite Disease Research Fields	Amyloid-β Natriuretic Peptide Receptor (NPR) α-synuclein Transthyretin (TTR) Claudin
Homogentisic acid is an orally active, blood-brain barrier-permeable amyloidogenic compound that functions as both an amyloid component and a pigment precursor. Accumulation of homogentisic acid downregulates tight junction proteins (such as claudin-5, occludin, ZO-1) and impairs blood-brain barrier integrity. Homogentisic acid and its oxidation product benzoquinone acetic acid not only induce the aggregation and fibrosis of multiple proteins (such as Aβ_1-42, α-synuclein, SAA, Transthyretin (TTR), atrial natriuretic peptide), but also trigger oxidative stress, damage to the *Wnt/β-catenin* pathway, and neurotoxicity, leading to ochronosis pigment deposition and synaptic dysfunction. At specific concentrations, homogentisic acid exerts no cytotoxicity or genotoxicity on human peripheral blood lymphocytes, and even counteracts the genotoxicity induced by Irinotecan (HY-16562). Homogentisic acid serves as an important tool molecule for investigating the mechanisms of diseases including ochronosis, secondary amyloidosis, Alzheimer's disease, and colorectal cancer .

Methyllycaconitine MLA	Structural Classification Alkaloids Piperidine Alkaloids Ranunculaceae Delphinium ajacis Plants Source Classification	nAChR
Methyllycaconitine (MLA) is a potent, selective, CNS-penetrant, competitive α7nAChR antagonist. Methyllycaconitine alleviates amyloid-β peptides-induced cytotoxicity in SH-SY5Y cells. Methyllycaconitine prevents methamphetamine-induced effects in mouse striatum. Methyllycaconitine can be used for neurological disease research, such as Alzheimer’s disease .

β-Amyloid (1-42), human, Ala(13C3,15N) TFA

β-Amyloid (1-42), human, Ala( ¹³C₃, ¹⁵N) TFA is the ¹³C and ¹⁵N-labeled β-Amyloid (1-42), human (HY-P1363A). β-Amyloid (1-42) (Amyloid β-peptide (1-42)), human, a 42-amino acid peptide that has not been treated with HFIP, is a brain-penetrant amyloid protein fragment, which can be used in research on Alzheimer's disease and Down’s syndrome. β-Amyloid (1-42), human remaining as a monomer exhibits antioxidant and neuroprotective effects. β-Amyloid (1-42), human, after being monomericized by HFIP and dissolved in DMSO to form the stock solution, on the one hand, can form soluble oligomers (AβOs) when incubated at 4 °C, which have synaptic toxicity and neurotoxicity; on the other hand, it can be incubated at 37 °C to form insoluble fibrils, with lower neurotoxicity, and participating in the oxidative damage process. Aβ42 oligomers bind to various neuronal surface receptors (such as PrPc, mGluR5, NMDA receptors, etc.), triggering oxidative stress, calcium homeostasis imbalance, and synaptic toxicity via activating downstream signaling pathways, leading to neuronal dysfunction and death .
