Coffee Cherry

Cafestol has anticarcinogenic, peripheral antinociceptive and anti-inflammatory activities, it inhibits Cyclic-Strain-induced interleukin-8, intercellular adhesion molecule-1, and monocyte chemoattractant protein-1 production in vascular endothelial cells. Cafestol is a novel extracellular signal-regulated kinase inhibitor with AP-1-targeted inhibition of prostaglandin E2 production in lipopolysaccharide-activated macrophages. Cafestol acts as an agonist ligand for both FXR and PXR, and this may contribute to its impact on cholesterol homeostasis. Cafestol has protective effects against the CCl(4)-induced hepatotoxicity, which possibly involve mechanisms related to its ability to block the CYP2E1-mediated CCl(4) bioactivation and free radical scavenging effects. Cafestol has antidiabetic activity, it increases glucose-stimulated insulin secretion in vitro and increases glucose uptake in human skeletal muscle cells. Cafestol also has a weak inhibitory effect on osteoclastogenesis and promotes osteoblast differentiation.

Kahweol has anticarcinogenic, anti-angiogenic,and anti-inflammatory activities, it can block the LPS-induced activation of NF-kappaB by preventing IkappaB degradation and inhibiting IkappaB kinase activity. Kahweol also has hepatoprotective and antioxidant effects on carbon tetrachloride-induced liver damage in mice.
