Syringaldehyde is a polyphenol that has been found in E. granulatus and has diverse biological activities.1,2,3,4 It inhibits LPS-induced COX-2 activity in RAW 264.7 cells with an IC50 value of 19.23 ?M.1 Syringaldehyde inhibits the proliferation of HCT116, Caco-2, and HT-29 colon cancer cells (IC50s = 56.3, 35.9, and 68.6 ?M, respectively).2 It decreases plasma glucose levels in a rat model of diabetes induced by streptozotocin when administered at doses ranging from 1.8 to 7.2 mg/kg.3 Syringaldehyde (25 and 50 mg/kg) reduces infarct size in a rat model of myocardial infarction induced by isoproterenol .4
