- FIG. 5 illustrates the increase in the resistance of fibroblasts subjected to the action of oxidative stress (increasing concentration of t-BHP) in the presence or in the absence of coelenteramine.
- FIG. 6 illustrates the reduction in the release of lactate dehydrogenase by rat hepatocytes when increasing doses of coelenteramine are added to the culture medium. Examples
- Coelenteramine is a natural product found in marine organisms, which is derived from the oxidation of coelentrazine.
- the structure of coelenteramine is illustrated below. This structure has the following characteristics:
- Example 1 Stability Coelenteramine is characterized by excellent oxygen stability, both in powder form and after solubilization in aqueous and organic solvents. Indeed, this molecule is not altered by a stay of several days in aqueous solvent exposed to air. After several days, no degradation product of coelenteramine was identified after chromatographic analysis in HPLC and TLC.
- Example 2 Toxicity Coelenteramine is characterized by an absence of toxicity both on hepatic cells and on intestinal cells or fibroblasts.
- Coelenteramine was applied to primary cultures of rat hepatocytes seeded in microplates (20,000 cells per well, 200 ⁇ l). The doses in CLM ranged from 1.3 ⁇ 10 -5 to 5 ⁇ 10 -4 M. After a period of 24 hours, their survival was evaluated by measuring the total protein content in each well (Bradford method). The results, represented in FIG. 1, expressed as a percentage of the survival of the controls not treated with CLM, demonstrate that the latter is not at all toxic for hepatocytes at these concentrations. of the Similar results were obtained on human fibroblasts (MRC-5) as well as human intestinal cells (CAC02).
- LDL low-density lipoproteins
- vitamin C ubiquinone
- ⁇ -carotene represent the other main antioxidant molecules of LDL. It has been demonstrated in vitro that the transformation of macrophages into foam-charged lipid cells (which are the main constituents of atherosclerotic plaque) is linked to a change in the oxidative nature of LDL.
- the oxidation of LDL is a process mediated by free radicals and initiated by the peroxidation of polyunsaturated fatty acids after consumption of antioxidants.
- the oxidation of LDL greatly increases the atherogenic properties.
- Epidemiological studies have shown an inverse relationship between cardiovascular mortality and the plasma concentration of antioxidants (such as vitamin E). Consequently, water- and fat-soluble antioxidants can protect LDL and delay or prevent their oxidation process.
- the in vitro oxidation of LDL is compared in the absence or in the presence of variable concentrations of coelenteramine.
- the oxidation of polyunsaturated fatty acids from LDL is accompanied by the formation of conjugated dienes which have a maximum absorbance at 234 nm.
- conjugated dienes result from the rearrangement of the double bonds of polyunsaturated fatty acids following the abstraction of a malonic hydrogen. The increase in the absorption of conjugated dienes can be directly measured in solution without having to use lipid extraction.
- the oxidation of LDL can be catalyzed by metal ions such as copper or triggered by a water-soluble radical initiator such as 2,2'-azobis (2-amidinopropane) (AAPH).
- metal ions such as copper
- AAPH 2,2'-azobis (2-amidinopropane)
- an LDL solution (final concentration of 50 ⁇ g protein / ml of PBS buffer, pH 7.4) is incubated in the presence of 5 ⁇ M of copper or 2 ⁇ M of AAPH and in the absence or in the presence of presence of variable CLM concentrations in a quartz cuvette having an optical path of 1 cm.
- the absorbances at 234 nm of the different samples are measured as a function of time on a UV-visible spectrophotometer (DU-8, Beckman).
- a blank is obtained using an LDL-free phosphate solution but containing 5 ⁇ M CuCl2 • 2H2O and 2.5 ⁇ M CLM.
- the tests are carried out at 30 ° C for the oxidation of LDL in the presence of copper and at 37 ° C in the presence of AAPH.
- FIG. 3 illustrates the delay in the appearance of TBARS (thiobarbituric acid reactive substances), corresponding essentially to malonaldialdehyde (MDA), product of the oxidation of lipids contained in LDL.
- TBARS thiobarbituric acid reactive substances
- MDA malonaldialdehyde
- FIG. 4 illustrates the survival of hepatocytes subjected to the action of NF 3 10 -4 M for 6 hours. At the end of this treatment, the survival (estimated by the MTT method) was 18% in the control groups.
- the survival was 18% in the control groups.
- FIG. 6 illustrates the reduction in the release of lactate dehydrogenase (LDH), indicative of cytotoxicity, by the cells when the CLM (10 and 50 ⁇ M) is added to the culture medium. Mortality, which is 75% in controls, only reaches a few% in the presence of 50 ⁇ M CLM.
