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].

(Met(O2)35)-Amyloid β-Protein (1-42) is a peptide [1].

42-(2-Tetrazolyl)rapamycin is a prodrug compound derived from a rapamycin analog.

1. Licochalcone B (LCB) inhibits the proliferation of human malignant bladder cancer cell lines (T24 and EJ) in vitro and antitumor activity in vivo in MB49 (murine bladder cancer cell line) tumor model. 2. LCB and Licochalcone D(LCD) significantly reduce

(Glu20)-Amyloid β-Protein (1-42) represents a variant of amyloid β-protein (Aβ) that fibrillizes more slowly due to the Glu20 mutation, which diminishes Aβ42's tendency to aggregate and inhibits the accumulation of this slowly fibrillizing peptide. Amyloid β-protein is the principal constituent of amyloid deposits in the vascular system and brain parenchyma in Alzheimer's disease [1] [2].

Amyloid-β (1-42) (Aβ42) is a neurotoxic 42-amino acid protein fragment found in amyloid plaques in postmortem cerebral cortex from patients with Alzheimer's disease.1,2,3Aggregation of Aβ42 results in the formation of neurotoxic fibrils or globular oligomers.1Aβ42 accumulates in the brain of many transgenic mouse models of Alzheimer's disease and, in many models, the onset of amyloid deposition positively correlates with deficits in spatial learning and memory.4 1.Wolfe, M.S.Therapeutic strategies for Alzheimer's diseaseNat.

Amyloid-β (1-8, A2V) is a truncated form of amyloid-β (Aβ) that contains a valine to alanine substitution at position 2 of the Aβ numbering convention (Aβ A2V), which corresponds to position 673 of the amyloid precursor protein (APP) numbering convention (APP A673V). An Aβ (1-40) (Aβ40) A2V peptide increases the production of Aβ and the rate and amount of amyloid fibril formation in vitro, effects that can be reduced by coincubation with wild-type Aβ40. Aβ40 and Aβ42 levels are increased in CHO cells expressing the Aβ A2V mutation and in fibroblasts derived from patients with the Aβ A2V mutation. As a homozygous mutation, Aβ A2V is correlated with Alzheimer's disease with distinctive pathological features, but disease does not develop in patients with a heterozygous Aβ A2V mutation.

Donecopride is a partial agonist of the serotonin (5-HT) receptor subtype 5-HT4E(Ki= 8.5 nM) and an inhibitor of acetylcholinesterase (AChE; IC50= 16 nM).1It is selective for AChE over butyrylcholinesterase (BChE; IC50= 3,530 nM) but does bind to 5-HT2Band sigma-2 (σ2) receptors (Ki= 1.6 nM for both) in a panel of 42 neurotransmitter receptors and transporters. Donecopride induces release of soluble amyloid precursor protein-α (sAPP-α) in COS-7 cells transiently expressing 5-HT4with an EC50value of 11.3 nM. Oral administration of donecopride (1 mg/kg) reduces brain soluble and insoluble amyloid-β (1-42) levels and increases the time spent exploring the novel object in the novel object recognition (NOR) test in the 5XFAD transgenic mouse model of Alzheimer's disease. Donecopride (3 mg/kg, p.o.) prevents a reduction in spontaneous alternation behavior induced by intracerebroventricular administration of soluble Aβ42 (sAβ42) in the Y-maze in mice.2 1.Lecoutey, C., Hedou, D., Freret, T., et al.Design of donecopride, a dual serotonin subtype 4 receptor agonist/acetylcholinesterase inhibitor with potential interest for Alzheimer's disease treatmentProc.
