The molecule is a member of the class of chalcones that is trans-chalcone substituted by a methyl group at position 3', hydroxy groups at positions 2' and 4' and a methoxy group at position 6'. Isolated from the buds of Cleistocalyx operculatus, it has been shown to exhibit inhibitory effects on the viral neuraminidases from two influenza viral strains, H1N1 and H9N2. It has a role as a plant metabolite and an EC 3.2.1.18 (exo-alpha-sialidase) inhibitor. It is a member of chalcones, a monomethoxybenzene and a member of resorcinols. It derives from a trans-chalcone.
