Researchers investigated the activity of different parts of Korean thistle for their potential to inhibit diabetes and Alzheimer's disease. Ethyl acetate and dichloromethane fractions of the leaf extract showed α-glucosidase and BACE1 inhibitory activity, respectively. Luteolin, an isolated compound, also exhibited non-competitive inhibition against both α-glucosidase and BACE1. Docking studies showed that luteolin formed a strong hydrogen bond with the peripheral binding amino acid residues and hydrophobic interactions with the enzymes. Korean thistle may be a dietary supplement against these diseases, especially the leaves, due to the preponderance of active luteolin. This promising candidate warrants further in vitro and in vivo studies.
