Tricin is a flavone that has been found in O. sativa and has diverse biological activities.^1,2,3,4 It scavenges ABTS radicals in a cell-free assay (IC50 = 0.312 mg/ml).¹ Tricin (0.1-10 µM) reduces virus titer and expression of the human cytomegalovirus (HCMV) genes IE1 and UL54 in HCMV-infected human embryonic lung fibroblast (HEL) cells, an effect that can be reversed by overexpression of chemokine (C-C motif) ligand 2 (CCL2).² It inhibits IgE-induced degranulation of RBL-2H3 cells (IC50 = 4.83 µM).³ In vivo, tricin (37.5 mg/kg per day) reduces tumor growth and the number of lung metastases in a CT26 murine colon carcinoma model.⁴
