- X x represents an N-protecting group as defined above and
- X 2 represents a group of formula R.
- addition salts with pharmaceutically acceptable acids is meant the salts which give the biological properties of the free bases, without having an undesirable effect.
- These salts can be in particular those formed with mineral acids, such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid; acidic metal salts, such as disodium orthophosphate and monopotassium sulfate, and organic acids, such as formic acid, acetic acid, propionic acid, glycolic acid, oxalic acid, fumaric acid, lactic acid, succinic acid, tartaric acid and pamoic acid.

- acidic metal salts such as disodium orthophosphate and monopotassium sulfate
- organic acids such as formic acid, acetic acid, propionic acid, glycolic acid, oxalic acid, fumaric acid, lactic acid, succinic acid, tart
- the compounds of formula I can be prepared in a conventional manner by peptide synthesis in liquid or solid phase, by successive couplings of the various amino acid residues to be incorporated, from the C-terminal end to the N-terminal end, and whose the N-terminal ends and the reactive side chains are previously blocked by groups such as those mentioned below:
- REPLACEMENT SHEET - lateral ends of the aspartyl blocked by an ester group such as benzyl ester, of the arginyl: blocked by an H + (protonation) or tosyle group.
- the synthesis in liquid phase of a compound of formula I can be carried out in six stages, eight stages if the last amino acid, N-substituted arginine, is not obtained commercially.
- the solvents used are most often dimethylformamide (DMF), tetrahydrofuran (THF), dioxane 1,4; coupling reagents dicyclohexyl carbodiimide (DCC), the catalyst hydroxybenzotriazole (HOBT).
- the first step (step A) consists first of all in preparing the C ⁇ -amide analogues of an aspartic acid protected in N ⁇ - and C ⁇ by reaction on the latter of an amine HNR 1 R 2 in the presence of an agent for coupling and catalyst, in a suitable solvent. After purification and control of its purity, the product is deprotected (step B) with a deprotection reagent characteristic of the protective group GP1.
- this amino acid derivative is transformed into a dipeptide (step C) by reaction of a protected glycine residue on its amino group (protective group GP4) in the presence of a coupling reagent and a catalyst in a suitable solvent.
- a coupling reagent or of a hindered base
- the protected dipeptide thus obtained is purified.
- Step D is a specific deprotection step of the protective group GP4.
- the dipeptide thus obtained, after purification is reacted with an arginine residue protected in N ⁇ and in N G (H * ) (step E) in the presence of a coupling agent and a catalyst, in an appropriate solvent, l addition of an equivalent of triethylamine is carried out when the deprotected dipeptide is obtained in protonated form.
- the tripeptide product obtained is purified and then treated with a protective reagent for the protective group GP2, thereby releasing the carboxylate function from the aspartic residue (step F) to give the terminal tripeptide of formula I.
- Each terminal tripeptide is studied in Fast Atom Bombardment Positive Mode (FAB + ) in a glycerol or thioglycerol matrix.
- FAB + Fast Atom Bombardment Positive Mode
- the dipeptide derivative I, C (8 g; 0.017 mol) is dissolved in ethyl acetate (300 ml) at 0 ° C. The solution is treated at this temperature by bubbling HCl gas. The deprotection reaction is followed by TLC over 2 hours. After degassing with nitrogen, the ethyl acetate is evaporated by half at room temperature under vacuum. The crystals formed are recovered by filtration, washed with ethyl ether and dried under vacuum (6.7 g; 0.0165 mole; 97%).
- the finely pulverized N ⁇ -acetylarginine dihydrate (1.86 g; 0.00738 mole) and the compound obtained in d) (3 g; 0.00738 mole) are dissolved in DMF (200 ml) at room temperature. After 20 minutes of stirring, the DCC (1.52 g; 0.00738 mole) and the HOBT (0.998 g; 0.00738 mole) are added. The whole is stirred for 3 days. The insoluble material is filtered and the DMF is evaporated under vacuum. The residue is taken up in the minimum amount of dichloromethane and the insoluble material is filtered. The solvent is evaporated and the residue triturated with ethyl acetate, then ethyl ether.
- the protected tripeptide obtained in e) (3 g; 0.005 Mole) is reduced in methanol (100 ml) with hydrogen in the presence of a 5% Pd / carbon catalyst (0.3 g) at room temperature overnight. The whole is then filtered through celite and the methanol evaporated to give the desired compound in the form of a hydroscopic white powder (2.3 g; 0.0045 mole; 90%).

- the lens is extracted from the bull's-eye via the posterior surface.
- the lens is stored in phosphate buffer without calcium or magnesium (Phosphate Buffer Saline).
- the lenses are frozen at -20 ° C at this stage, the anterior capsule is cut using small scissors and placed on the bottom of a culture dish. Incubation with 1% Triton XlOO for 30 minutes allows cells to take off crystalline epithelials adherent to the capsule.
- the capsules are then rinsed three times with PBS. Before use, each capsule is observed under an optical microscope in order to verify the total absence of cells on the capsule.
