Abstract:

The healthy benefits of hemp (L.) seed have often been attributed to its oils and proteins. Recent studies reveal that hemp seed phenylpropionamides could also show various bioactivities. Continuation of our study on hemp seed provided a phenylpropionamide, coumaroylaminobutanol glucopyranoside (CLG). This work investigated the neuroprotective effect of CLG and its underlying mechanism using lipopolysaccharide-induced BV2 microglia. Our study demonstrated that CLG increased adenosine monophosphate-activated protein kinase (AMPK) expression, suppressed the nuclear factor-kappa B (NF-κB) signaling pathway by inhibiting the phosphorylation of IκBα and NF-κB p65 and decreased proinflammatory cytokine levels in a concentration-dependent manner. Furthermore, CLG reduced the production of cellular reactive oxygen species and stimulated the nuclear factor erythroid 2-related factor 2 (Nrf-2) signaling pathway. Collectively, these results suggested that CLG effectively and simultaneously inhibited inflammatory responses and oxidative stress through the NF-κB and Nrf-2 signaling pathways. AMPK was also involved in the anti-inflammatory effect of CLG. This study provides new insights into the diverse bioactive constituents of hemp seed.
