- FIG. 1 represents the structure of the imidazolopyrazine derivatives used in the pharmaceutical and food composition according to the invention.
- FIG. 2 represents the relation uniting the concentration of superoxide dismutase (SOD) and the ratio of the intensities measured in the absence and in the presence of superoxide dismutase (I 0 / I) for two concentrations of coelenterazine
- FIG. 3 represents the evolution of the slope of the relation uniting the concentration of superoxide dismutase and I 0 / I and of the speed constant
- FIG. 4 represents the linear relationship between the concentration of coelenterazine and the maximum intensity of the luminescence evoked by the superoxide anion in our experimental conditions.
- FIG. 5 represents the inactivation of superoxide dismutase by KCN 10 -2 M. The enzymatic activity is totally inhibited by KCN, and no more difference is perceptible between the two concentrations of coelenterazine (10 -7 and 4 ⁇ 10 -7 M).
- FIG. 6 represents the influence of the luminol concentration on the slope of the relationship uniting the superoxide dismutase concentration and the ratio of the intensities I 0 / I.
- FIG. 7 represents the stability of derivative 10 in an aqueous medium.
- Three 10 -5 M CLZN-10 solutions were prepared in citrate (pH 4), phosphate (pH 7) and glycine (pH 10) buffers. Aliquots of these solutions were removed regularly and the CLZN-10 assayed by luminescence in DMSO.
- FIGS. 8 and 9 represent the percentage of cell survival of human fibroblasts subjected to an oxidative stress inducer in the presence of increasing doses of derivatives according to the invention, with (FIG. 9) or without (FIG. 8) serum.

- the main reaction mechanism would be comparable to that involved in the chemoluminescent oxidation of coelenterazine by molecular oxygen.
- reaction product is not a stable and not very reactive radical.
- excited product formed would be characterized by very great instability. This is such that these products seem to disintegrate instantly by rupture of the nucleus imidazolopyrazine; part of the destructive energy of the ROS is dissipated in the form of light while the rest is released in the form of thermal radiation.

- Oily phase the powdered ingredients are incorporated into the mixture of oils, to which the melted butter and possibly a colorant are added. This fat phase is stored at 55 ° C.
- Aqueous phase the gelatin is dispersed in water at 80 ° C, the other ingredients are added and the pH is adjusted to 5 with lactic acid. The mixture is mixed until a homogeneous mass is obtained and the aqueous mixture is stored at 55 ° C.
- the aqueous phase is then slowly incorporated with vigorous stirring into the fatty dispersion at 55 ° C.
- We the product is then homogenized at 200 bars and then allowed to cool quickly to 12 ° C.
- the product is packaged in trays and kept refrigerated before administration to a patient.
