| In vitro study | Syringaldehyde inhibits COX-2 activity in a dosedependent manner with an IC 50 of 3.5 μg/mL. |
| In vivo study | Syringaldehyde exerts anti-hyperglycemic effect in rat model of diabetes induced by streptozotocin. Apart from antioxidant capability, Syringaldehyde also has anti-inflammatory activity as it is found to have inhibitory action on cyclo-oxygenase 2 (COX-2) in mouse macrophage cell line. |
