Due to their structural similarities, PT exhibits pharmacological functions that are similar to well-studied resveratrol, including anti-oxidant, anti-inflammation, anti-cancer and anti-diabetes activities.[19] Resveratrol contains three hydroxyl groups, whereas PT has two methoxy groups and one hydroxyl group; the two methoxy groups are responsible for the relatively increased lipophilicity and enhanced cell membrane permeability of PT. This evidence concerns the gene F2 and diabetes mellitus.
