| Bioactivity | Carmoisine (Azorubine) is an azo dye that can be used as a food additive[1][2]. Storage: protect from light. |
| Invitro | Carmoisine augments the in vitro synthesis of leukotriene B4 (LTB4) and F2-isoprostanes from blood neutrophils. Carmoisine increases the formation of F2-isoprostanes from blood neutrophils at all tested concentrations[2]. |
| In Vivo | Carmoisine (49.3-493 mg/kg; oral administration; for 42 days; male Wistar rats) treatment increases MAPK8 expression at remarkably low and high concentrations, the expression of NFκB and GADD45α does not change[1]. Animal Model: |
