- polymerization can be carried out from aminoacetaldehyde-diethylacetal:
- the protocol used is as follows: protected from light, 100 mg of acetal are dissolved in 2 ml of water and 200 ⁇ l of 4N HCl; the mixture is placed in an oven at 37 ° C. with stirring for 30 minutes. 4 ml of 3M pH 8 acetate are added. The mixture is placed in an oven at 37 ° C., with stirring, for 2 hours.
- the imine reduction and purification steps are carried out in the same manner as in the glutaraldehyde polymerization.
- the conjugates of formula XYZ according to the present invention can be obtained by coupling methods well known to those skilled in the art, between a functional group of each of the molecules X and Z, optionally via succinic or glutaric anhydride . Examples of coupling agent which can be used for the purposes of the invention include, in particular, carbodiimide, ethyl chloroformate or hexamethylene diisocyanate.
- the compound Y is for example glutarylated or succinylated in the following way: 10 mg of the compound Y are dissolved in 1 ml of water [or 200 ⁇ l of dimethylsulfoxide (DMSO) and 800 ⁇ l of water], 8 are added, 5 mg of succinic or glutaric anhydride and 85 ⁇ l of 1N sodium hydroxide by vortexing the mixture. At the end of this step, the solution is frozen and lyophilized.
- the freeze-dried product is the compound: Y-succinylated or Y-glutarylated with a free carboxyl which can be activated with carbodiimide (aqueous medium) or with ethyl chloroformate (ECF, anhydrous solvent).
- the Y-succinylated or Y-glutarylated product is attached to the X-Z assembly.

- the compounds according to the present invention have an excellent ability to trap metal ions in solution by forming a coordination complex with said ions.
- the invention relates to a method for recovering metal ions in solution, which comprises the following steps: - bringing a solution containing metal ions into contact with a compound as defined above for form a complex;
- a dialysis apparatus As a filtration device, a dialysis apparatus, an ultrafiltration membrane or preferably an affinity chromatography column are advantageously used. In the latter case, it is necessary that the pH of the column is maintained at a value greater than or equal to 8 during the passage of the complex in order to maintain the -NH- or -NH 2 groups of the diamines and / or polyamines under this form.
- the metal ions are recovered by adding to the dyalisate a solution of a mineral acid such as hydrochloric acid or an organic acid buffer such as a glycine buffer, or washing of the membrane or of the column by such a solution.
- Another advantage of the process according to the invention lies in the fact that it is possible to regenerate the compounds used, in particular by treating the filter used with a buffer solution whose pH is greater than or equal to 7.4.
- the process according to the invention is therefore both simple and economical. Thanks to their properties, the compounds according to the invention can be used in different applications, for example:
- G reduced glutaraldehyde residue MDA: para, para'-methylenedianiline blend 1: poly (ORN-G) + poly (PU-G) + poly (CD-G) + poly (SPD-G) + poly (SPM-G ) blend 2: poly (SPD-G) + poly (SPM-G)
- ORN L-omithine PL: poly-L-lysine PU: putrescine SPD: spermidine SPM: spermine
- EXAMPLE 1 Filtration by dialysis 1 - Piéqeaqe / salargage du cuiyre a) - 2 ml of a solution containing copper sulphate, brought into contact with a compound according to the invention, are dialysed against water (liter). A sample of the dialysate is taken to the Departmental Laboratory for Water Analysis in Pau to quantify the quantity of metallic ion released.
- the quantity of Cu2 + ion released was determined according to the techniques used at the departmental laboratory for water analysis in Pau: the CDERE. In this laboratory, we used the methods of quantification of ions called:
- CD-AG-mixture 1 CD-AG-mixture 1; CARN-AG-PL and PU- AG-mixture 1.
- a large part of the Cu 2+ trapped by the mixture 2 is released after acid treatment.
- the mixture 2 is pH-sensitive, therefore after treatment allows recycling of the retained ions.
- Polyamines can be reused after washing in buffer solutions with a pH> 7.4.
- the ratio of the copper concentration of the ultrafiltered solution to the initial copper concentration (Cf / Ci) increases as the ultrafiltered volume (V) increases.
- the column consists of 2 g of Sepharose gel activated with cyanogen bromide (REF: Pharmacia Code N ° 17-0430-01) to which a mixture of polyamines (mixture 1) has been fixed.
- REF Pharmacia Code N ° 17-0430-01
- the volume of the column is 7.4 ml.
- the concentration of sample 4 which corresponds to 800 ml of water filtered on the column, is 61.22 ⁇ g / l. It gives us the quantity of Cu 2+ retained by the column, 2.351 mg and the percentage of Cu + retained is therefore 97.95%.
- the concentration of sample 5, which corresponds to the elution, is 43.94 mg / l. It gives us the quantity of Cu released, 2.197 mg.
- the flow rate of the column is 500 ml / h
- the Cu 2+ concentration is divided by 1969.2 between the outlet water and that to be decontaminated, which confirms the need for coupling with the Tris to maintain a pH above 8 in order to maintain the NH 2 and NH groups under this form.
- the Zn + concentration of the filtered solution (sample 7.7) is 14.36 mg / l. So the amount of Zn 2+ that was captured is 7.23 mg. It is noted that for the Zn 2+ ions it is necessary to increase the amount of Tris fixed on the gel in order to have a slower decrease in pH and to obtain a good yield for trapping these ions. 3.3 - conclusion - the column system is applicable in an industrial environment. Its cost is low in comparison with the means available to manufacturers today, such as ion exchange resins;
- copolyamine having the highest number of NH and NH2 has a higher buffering capacity, therefore here copolyamine 5 which corresponds to the copolyamine on which spermine has been coupled with the carbodiimide.
- copolyamine 5 which corresponds to the copolyamine on which spermine has been coupled with the carbodiimide.
- a pH test is carried out between copolyamine 5 and mixture 2, which so far has had the strongest buffering capacity.
- the polyamine which has the most important buffering capacity is copolyamine
- the encephalitogenic peptide has the following sequence:
- the rats came from the January Breeding Center. During all the experiments, the animals were put under the breeding conditions required by legislation. The rats are injected with the encephalitogenic mixture (PE and Mycobacterium) and then distributed randomly in each group.
- PE and Mycobacterium encephalitogenic mixture
- the animals were observed clinically every working day after administration of the encephalitogenic emulsion.
- the tests are based on a few criteria relating to:
- the average weight development of the group treated with the 0.7 W 0.3 -G SPD copolymer is not different from that of the control group.
- the advantage of the SPDo copolymer, W 0 ⁇ 3 - G is confirmed: the compound is not sufficient to abolish the brain attack, but it reduces it by half in its intensity and its duration . Here it was administered 12 days before the onset of the attack.
