Kahweol is one of the consituents of the coffee from Coffea Arabica with anti-inflammatory anti-angiogenic, and anti-cancerous activities. Kahweol inhibits adipogenesis and increase glucose uptake by AMP-activated protein kinase (AMPK) activation. Kahweol induces apoptosis.
Kahweol (20-40 μM; 24 hours) decreases TGF-β-induced CTGF protein expression in AML12 and LX2 cells[1].Kahweol (20-40 μM; 1 hour) decreases TGF-β-induced phospho-Smad2/3 expression in AML12 cells, but does not affect expression in LX2 cells[1].Kahweol (20-40 μM) significantly decreased TGF-β-stimulated phospho-ERK and JNK expression in primary hepatocytes only[1].kahweol (0-25 μg/ml; 6-24 hours) increased the phosphorylation of AMPK and its downstream target Acetyl-CoA carboxylase (ACC) in a time-dependent manner in 3T3-L1 cells[2].kahweol (0-25 μg/ml) significantly affects protein expression of PPARγ, C/EBPα, FABP4, and FASN, that regulate adipocyte differentiation and lipid metabolism[2].
