amyloid β42

Ro 90-7501 is an amyloid β42 (Aβ42) protofibrillar and TPR-dependent PP5 inhibitor, a novel radiosensitizer for cervical cancer cells, which inhibits ATM phosphorylation, promotes apoptosis, and induces cell-cycle arrest. Ro 90-7501 also exhibits antiviral activity and potential anticancer activity by inhibiting ATM phosphorylation and DNA repair, and by inhibiting HCMV.

Lawsoniaside can hinder the growth of amyloid-β42 fibrils.

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].

WRW4 TFA is a formyl peptide receptor-like 1 (FPRL1) antagonist that specifically prevents the binding of WKYMVm to FPRL1 with an inhibition concentration (IC50) of 0.23 μM. It uniquely blocks the rise in intracellular calcium triggered by FPRL1 agonists such as MMK-1, amyloid beta42 (Abeta42) peptide, and F peptide [1].

2-O-Acetyl-20-hydroxyecdysone is an ecdysone present in insects and terrestrial plants. 2-O-Acetyl-20-hydroxyecdysone inhibits amyloid-β42-induced cytotoxicity and is able to reduce the formation of Aβ oligomers by promoting fibrillogenesis, which converts Aβ oligomers into less toxic fibers.
