Background: Grains of paradise (GP) is the seed of Aframomum melegueta, which is widely distributed throughout West Africa and has been used as a spice and a folk remedy for a long time. Anti-obesity effect of GP intake was demonstrated in a previous report. Aim of the present study was to isolate some compounds in GP and clarify the anti-obesity mechanism.
Results: Ten vanilloid compounds were isolated. Among them, 1-(4′-hydroxy-3′-methoxyphenyl)-decan-3-ol and 1-(4′-hydroxy-3′-methoxyphenyl)-3-octen-5-one were determined as novel compounds and 6-gingerol, 6-paradol and 6-shogaol were identified as the major constituents in GP extract. Moreover, the extract and 6-gingerol, which is one of the principal components of GP extract, were orally administered to rats to investigate the effect on sympathetic nerve activity (SNA) in brown adipose tissue (BAT). The injection of GP extract and 6-gingerol decreased BAT-SNA, whereas capsaicin, which is a major component of chili pepper, activates the sympathetic nervous system.
Conclusion: This study suggested that GP extract and 6-gingerol were largely unrelated to the anti-obesity effect by the activation of interscapular BAT-SNA and had a different anti-obesity mechanism to capsaicin. © 2018 Society of Chemical Industry.

Paradols are unsaturated ketones produced by biotransformation of shogaols in gingers. Among them, 6-paradol has been investigated as a new drug candidate due to its anti-inflammatory, apoptotic, and neuroprotective activities. In this study, the inhibitory effects of 6-paradol on the activities of cytochrome P450 (CYP) enzymes were investigated with human liver microsomes and recombinant CYP isozymes. 6-Paradol showed concentration-dependent inhibitory effects on CYP1A2, CYP2B6, CYP2C8, CYP2C9, and CYP2C19 isozymes, with IC50 values ranging from 3.8 to 21.4µM in recombinant CYP isozymes. However, the inhibition was not potentiated following pre-incubation, indicating that 6-paradol is not a mechanism-based inhibitor. These results suggest that pharmacokinetic drug-drug interactions might occur with 6-paradol, which must be considered in the process of new drug development.

The anti-diabetic activity of ginger powder (Zingiber officinale) has been recently promoted, with the recommendation to be included as one of the dietary supplements for diabetic patients. However, previous studies presented different results, which may be caused by degradation and metabolic changes of ginger components, gingerols, shogaols and paradols. Therefore, we prepared 10 ginger active components, namely 6-, 8-, 10-paradols, 6-, 8-, 10-shogaols, 6-, 8-, 10-gingerols and zingerone, and evaluated their anti-hyperglycemic activity. Among the tested compounds, 6-paradol and 6-shogaol showed potent activity in stimulating glucose utilization by 3T3-L1 adipocytes and C2C12 myotubes. The effects were attributed to the increase in 5′ adenosine monophosphate-activated protein kinase (AMPK) phosphorylation in 3T3-L1 adipocytes. 6-Paradol, the major metabolite of 6-shogaol, was utilized in an in vivo assay and significantly reduced blood glucose, cholesterol and body weight in high-fat diet-fed mice.
