Viscidulin III is present in Scutellaria baicalensis and acts as an α-glucosidase inhibitor.

Fz7-21 is a peptide antagonist of FZD7 . It antagonises WNT3A-induced Wnt-β-catenin signalling in HEK293 expressing FZD7. Fz7-21 impairs Wnt/β-catenin signaling in HEK293 cells stimulated with exogenous WNT3A (IC50=100?nM) or transfected with a construct expressing WNT3A or WNT1. Fz7-21 also blocks WNT3A-mediated stabilization of β-catenin in mouse L cells (IC50=50?nM).

2F-Peracetyl-Fucose (1,3,4-Tri-O-acetyl-2-deoxy-2-fluoro-L-fucopyranos) is a potent fucosyltransferase (FUT) inhibitor that suppresses salivary acidification and fucosylation in an in vitro inflammatory model.
