Carmoisine (Azorubine) is an azo dye that can be used as a food additive[1][2].

In Vitro

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Wistar rats (120-300 g)[1]
Dosage: 49.3 mg/kg, 493 mg/kg
Administration: Oral administration; for 42 days
Result: Resulted in apoptosis according to MAPK8 expression.
