Chemical Name: 3,4,5-Trihydroxybenzoic acid (2R,3R)-3,4-dihydro-5,7-dihydroxy-2-(3,4,5-trihydroxyphenyl)-2H-1-benzopyran-3-yl ester

Biological Activity

Inhibitor of amyloid assembly; inhibits the formation of amyloid fibrils by proteins such as Aβ, α-synuclein and huntingtin. Reduces Aβ42-induced cell death in three different cell types. Also inhibits β-secretase (IC50 = 1.6 μM) and glutamate dehydrogenase GDH. Inhibits cell growth and selectively induces apoptosis in A431 and human pancreatic cancer cells. Also a DNMT1 inhibitor.

Technical Data

Soluble to 10 mM in water and to 100 mM in ethanol
>99 %
Store at -20°C
