Abstract

Nuclear factor E2-related factor 2 (Nrf2) is the master regulator of antioxidant enzymes and is known to act on the nuclear factor kappa-light-chain-enhancer of activated B cell (NF-κB) signaling pathway. Few studies have examined the bioactivity of halleridone. Herein, we investigated whether halleridone, which was isolated from the stems of the plant Cornus walteri, could regulate Nrf2-mediated heme oxygenase (HO)-1 expression and prevent intramicroglial inflammation induced by amyloid beta (Aβ)1-42 overexpression. Biochemical and molecular experiments, such as real-time polymerase chain reaction, Western blot analysis, immunocytochemistry, immunofluorescence, and luciferase reporter gene assays, were performed. The results demonstrated that halleridone promoted the upregulation of Nrf2 expression and its translocation to the nucleus, thereby activating antioxidant response element gene transcription and HO-1 expression in murine hippocampal HT22 cells. Additionally, halleridone removed intramicroglial Aβ1-42 and suppressed the production of inflammatory mediators such as interleukin (IL)-1β, IL-6, prostaglandin E2, and nitric oxide (NO) induced by artificially overexpressed Aβ1-42 and decreased pNF-κB accumulation in the nucleus and the expression of inducible NO synthase and cyclooxygenase II in BV-2 cells. In conclusion, halleridone activated Nrf2-mediated HO-1 expression and inhibited Aβ1-42-overexpressed microglial BV-2 cell activation. These observations suggest that halleridone may have therapeutic potential for targeting neurodegeneration through neuroinflammation.

Abstract

Chemical investigation of the tubers of Sinningia allagophylla led to the isolation of two new chromenes, (2S)-12-hydroxylapachenole (1) and (3R)-3,4-dihydro-3-hydroxy-4-oxo-8-methoxylapachenole (2), and three new dimeric chromenes, allagophylldimers A-C (3-5). Thirteen known compounds, 6-methoxy-7,8-benzocoumarin (6), lapachenole, 8-methoxylapachenole, tectoquinone, 7-hydroxytectoquinone, dunniol, α-dunnione, dunnione, 8-hydroxydunnione, aggregatin E, cedrol, oleanolic acid, and halleridone, were also identified. 6-Methoxy-7,8-benzocoumarin (6) has been isolated for the first time from a natural source.

Abstract

A new naphthoquinone, 6-methoxy-7-hydroxy-a-dunnione (1), along with four known compounds (2, 4, 10, and 11) were isolated from Sinningia canescens (Mart.) Wiehler tubers, while S. warmingii (Hiern.) Chautems furnished eight known compounds (3-10). The known compounds were identified as 7-hydroxy- α-dunnione (2), lapachenole (3), tectoquinone (4), 7-methoxytectoquinone (5), 1-hydroxytectoquinone (6), 7-hydroxytectoquinone (7), aggregatin C (8), aggregatin D (9), halleridone (10), and cedrol (11). In addition, S. canescens yielded a volatile fraction, which was analyzed by GC/FID and GC/MS. This fraction was constituted mainly by sesquiterpene hydrocarbons (82.6%). The major components were β-santalene (14.6%), β-cedrene (10.4%), and trans-cadina-1(6)-4-diene (10.0%).
