agaricoglyceride A

Wei Wang, Zhibiao Di, Ruiguo Li, Jingzhen Tian
Coprinus comatus, a novel cultivated edible mushroom, has a various of pharmacological effects due to its many active components. In this study, agaricoglycerides, a new class of fungal secondary metabolites that have strong activity against neurolysin, were isolated from C. comatus mycelia. Simultaneously, a 3-level Box-Behnken factorial design was used, combined with response surface methodology, to optimize the precursor composition of agaricoglycerides for the production of agaricoglyceride A. The model estimated that a maximal yield of agaricoglyceride A (20...

We have investigated the effects of agaricoglycerides (AG) in a mouse model of hepatic I/R injury. I/R triggered increases/changes in markers of liver injury, hepatic oxidative stress, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and nuclear factor κB (NF-κB). AG significantly reduced the extent of liver inflammation and oxidative stress and also attenuated the NF-κB activation as well as TNF-α and IL-1β production. Our results indicate that AG may represent a novel protective strategy against I/R-induced injury and inflammatory diseases...

The agaricoglyceride is a new fungal secondary metabolite that constitutes esters of chlorinated 4-hydroxy benzoic acid and glycerol. The objective of this study was to explore whether the administration of agaricoglyceride could correct hepatic glycemic metabolism dysfunction by attenuating inflammation in the liver. The effects of agaricoglycerides on tumor necrosis factor-α, interleukin-1β, vascular endothelial growth factor-α, interleukin-17, insulin secretion, adiponectin, leptin, hepatic glycogen, nuclear factor-κB activation, and total antioxidant activity were studied respectively...

The agaricoglycerides are a new class of fungal secondary metabolites that constitute esters of chlorinated 4-hydroxy benzoic acid and glycerol. They are produced in cultures of the edible mushroom, Agaricus macrosporus, and several other basidiomycetes of the genera Agaricus, Hypholoma, Psathyrella and Stropharia. The main active principle, agaricoglyceride A, showed strong activities against neurolysin, a protease involved in the regulation of dynorphin and neurotensin metabolism (IC50 = 200 nM), and even exhibited moderate analgesic in vivo activities in an in vivo model...
