Tricin can inhibit human cytomegalovirus (HCMV) replication by inhibiting CDK9. Tricin inhibits the proliferation and invasion of C6 glioma cells via the upregulation of focal-adhesion-finase (FAK)-targeting microRNA-7.

Methanol extract of Zizania latifolia was partitioned with EtOAc, n-BuOH, and H2O. From the EtOAc layers, a new flavonolignan along with a known flavone and three known flavonolignans, Tricin (1), salcolin A (2), salcolin B (3), and salcolin C (4), were isolated through repeated silica gel and ODS column chromatography. The chemical structure of the new flavonolignan was determined to be Tricin-4'-O-[erythro-β-guaiacyl-(7'-O-methyl)-glyceryl] ether and was named salcolin D (5) based on physicochemical and spectroscopic data, including FT-NMR and ESI-MS. All compounds were isolated for the first time from this plant. Compounds 2-5, Tricin derivatives, all exhibited higher anti-inflammatory and anti-allergy activities than Tricin. In particular, salcolin D (5) was shown to have the strongest inhibitory activity against LPS-induced NO production in RAW 264.7 cells as well as β-hexosaminidase release in IgE-sensitized RBL-2H3 cells[1]
