Popis: Oxidative stress contributes to the pathogenesis of various neurodegenerative diseases and induction of the Kelch-like ECH-associated protein 1 (Keap1)-nuclear factor erythroid 2-related factor 2 (Nrf2) pathway is a validated neuroprotective strategy. Synthetically-derived samples of members of the ribisin class of natural product together with a range of analogues were evaluated for their neuroprotective capacities. Four of the twenty-four compounds tested were found to strongly stimulate antioxidant response element-dependent transcriptional activity in human-derived SH-SY5Y cells. Further, in rat pheochromocytoma PC12 cells and mouse brain cortical cultures these compounds upregulated levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream target gene products, namely heme oxygenase (HO-1) and NAD(P)H quinone reductase 1 (NQO1). Functionally speaking, the compounds conferred protection in these cell models challenged with H
