一般描述
A cell-permeable dienone-phenolic triterpene compound that exhibits antioxidant and anti-inflammatory properties. It suppresses LPS-induced pro-inflammatory cytokines release in macrophages and monocytes (IC50 = 40 nM for IL-1β and IL-1α, 80 nM for IL-6, 110 nM for PGE2, and 210 nM for IL-8 and TNF-α), as well as LPS-induced NF-κB activation (IC50 = 270 nM) and NO production (IC50 = 230 nM) in RAW264.7 cells. Preferentially inhibits chymotrypsin-like activity of 20S proteasome with an IC50 of 2.5 µM. Has also been shown to inhibit lipid peroxidation induced by ADP and Fe2+ in rat liver mitochondria (IC50 = 7 µM). Significantly improves the performance in memory, learning, and psychomotor activity in rats. May be useful to minimize inflammation in Alzheimer′s disease (AD).

Amyloid and amyloid-like protein aggregations are hallmarks of multiple, varied neurodegenerative disorders, including Alzheimer's and Parkinson's diseases. We previously reported that spinocerebellar ataxia type 14 (SCA14), a dominant-inherited neurodegenerative disease that affects cerebellar Purkinje cells, is characterized by the intracellular
