fibrillogenesis

Eprodisate disodium (NC-503) is a negatively charged sulfonated inhibitor of fibrillogenesis, used in the treatment of amyloid A (AA) amyloidosis.

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.

Entacapone sodium salt inhibits catechol-O-methyltransferase(COMT) with similar IC50 in different tissues including live, duodenum, kidney and lung, but entacapone is more active than tolcapone in those tissues. Entacapone (< 100 μM) is a potent inhibitor of α-syn and β-amyloid (Aβ) oligomerization and fibrillogenesis, and also protects against extracellular toxicity induced by the aggregation of both proteins in PC12 cells.Entacapone sodium salt is a specific, potent, peripherally acting catechol-O-methyltransferase (COMT) inhibitor with IC50 of 151 nM for PD treatment.

Z-Phe-Ala-diazomethylketone directly binds to Aβ42 monomers and small oligomers, inhibiting Aβ42 dodecamer formation and preventing Aβ42 fibrillogenesis in solution. This compound holds potential for research into neurodegenerative disorders [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.
