Macelignan is a neuroprotective lingan isolated from nutmeg (Myristica fragrans) that protects dopaminergic neurons from inflammatory degeneration. Macelignans have been shown to possess a broad range of pharmacological properties, including anti-bacterial, antiinflammatory, and anti-cancer activity. It has also been demonstrated that macelignans have anti-diabetes, hepatoprotective, and more importantly, neuroprotective properties. Apparently, the neuroprotective effect of macelignan is mediated by PPARγ activation and arginase-1 expression. Macelignan inhibits LPS induced production of NO as well and inflammatory cytokines including TNF and IL- 1β in primary cultures of microglia. Macelignan reduced serum glucose, insulin, triglycerides, free fatty acid levels, and triglycerides levels in the skeletal muscle and liver of db/db mice. Furthermore, macelignan significantly improved glucose and insulin tolerance in these mice, and without altering food intake, their body weights were slightly reduced while weights of troglitazone-treated mice increased. Macelignan increased adiponectin expression in adipose tissue and serum, whereas the expression and serum levels of tumor necrosis factor-alpha and interleukin-6 decreased. Macelignan downregulated inflammatory gene expression in the liver and increased AMP-activated protein kinase activation in the skeletal muscle of db/db mice. Strikingly, macelignan reduced endoplasmic reticulum (ER) stress and c-Jun NH2-terminal kinase activation in the liver and adipose tissue of db/db mice and subsequently increased insulin signaling.

Sample Use Guides
Human dopaminergic neuroblastoma SH-SY5Y cells were used for activity evaluation. SH-SY5Y cells were maintained in DMEM culture medium (Solarbio, Beijing, China) with 10% calf serum (Sijiqing, Hangzhou, China), 100 U/mL penicillin, and 75 U/mL streptomycin in a 37 °C incubator (Heal Force HF-90, Hong Kong) in 5% CO2. Cells were trypsinized with 0.25% trypsin, counted, and seeded in 96-well culture plates (1 × 104 cells/well). After 24 h of incubation, the cells were pretreated with compound 8 (Macelignan) (0.08, 0.4, 2, and 10 μM) for 2 h before incubation in medium containing Aβ25−35 (1 μM). After 24 h of treatment, 15 μL of MTT (5 mg/mL) was added. For the MTT assays, the supernatant was discarded, and DMSO (100 μL/well) was added. The 96-well plate was vibrated on a microvibrator for 10 min, and the optical density at 570 nm was measured using a microplate reader.
