- Angiogenesis is a natural biological process of creating new blood microvessels from preexisting venules. It is a complex phenomenon that normally occurs in adults only under certain specific conditions such as wound healing, inflammation or the development of the corpus lutheum during the menstrual cycle. Under normal conditions, the angiogenesis process stops after an appropriate period of time indicating good regulation of the stimulating and inhibiting factors. Under certain pathological conditions such as the growth of solid tumors, rheumatoid arthritis, psoriasis and diabetic retinopathy, angiogenesis develops in a markedly less controlled manner ("Antiangiogenic agents and their promising potential in combined therapy". PA Burke, SJ DeNardo, Crit. Rew.

- Mitochondrial cytopathies include a wide variety of diseases, the common denominator of which is a deficit in the mitochondrial respiratory chain. Due to the ubiquitous presence of mitochondria in the body, this dysfunction can affect any organ. The involvement can be isolated or, on the contrary, multi-organ then generally having a dominant neuromuscular. There is currently no treatment for these diseases which can be classified as "orphan diseases". It is nevertheless now clear that since mitochondria are the privileged place in the cell for the production of free radicals, deficits in the respiratory chain are very often associated with an overproduction of free radicals, resulting in accelerated cell death in the affected tissues. Recent work done at Necker Hospital in the team of Dr P.
- Rustin Increased apoptosis in vivo in cells lacking mitochondrial DNA gene expression
- Wang J, Silva JP, Gustafsson C, Rustin P, Larsson NG. Proc Natl Acad Sci USA (2001) (in press) have shown the importance of this production of free oxygen radicals on a series of human cells in culture.
- These cell cultures represent all types of deficits affecting the various complexes of the respiratory chain known in humans. They have been characterized both from the point of view of the deficit affecting the respiratory chain and from the point of view of the production of free radicals and its consequences on cell survival. This collection of cells represents an irreplaceable tool for studying the effectiveness of any molecule targeting radical reactions associated with deficits in the respiratory chain.

- Table 1 Radioactivity measured in different organs of mice carrying B16 melanomas after IP injection of the molecule A (10 ⁇ Ci / animal).
- Example 2 preparation of the molecule E. This synthetic example is illustrated by FIG. 1.
- N- (tert-butyl) hydroxylamine acetate is dissolved in a saturated aqueous solution of sodium carbonate.
- the hydroxylamine is extracted with ether.
- the organic phase is dried over Na SO 4 then the solvent is removed under reduced pressure to yield free N-tert-butylhydroxylamine in the form of powdery white crystals.
- reaction mixture is filtered through a celite layer, the solvent is removed under reduced pressure and the crude is purified by flash chromatography on silica gel (eluent: ethyl acetate / cyclohexane 6: 4). After recrystallization from a methanol / ether mixture, the nitrone X (0.590 g - 2.67 mmol - 40%) is obtained in the form of a white powder.
- the lactobionolactone and amine 4 are dissolved in an argon atmosphere in 40 ml of methanol.
- the pH of the solution is brought to 9 by addition of TEA then the medium is brought to reflux for 24 hours.
- 40 ml of a 1: 1 acetic anhydride / pyridine mixture are added cold to the crude. Stirring is continued for 18 hours then the reaction mixture is poured onto 150 ml of IN HCl.

- 0.090 g of active ester X (0.28 mmol - 1 equiv.) are added to the medium and the pH is brought to 9 by addition of DIEA. Stirring is continued under an argon atmosphere for 24 hours.
- This synthesis is preceded by deprotection of the tripeptide according to the same protocol as for the synthesis of this tripeptide (compound 3). It is 500 mg (6.10 "4 mole) of 3 which are deprotected. Once deprotected, this peptide is dissolved in 10 ml of dichloromethane in a 100 ml flask. 278 mg (6.10 " 4 mole, leq) of compound 4 are added to the reaction medium. The reaction is carried out at room temperature under a stream of nitrogen, and is maintained at pH 8 using DIEA. After 16 hours, the reaction is complete (TLC).
- pentapeptide 5 is carried out under the same conditions as during the synthesis of compound 1. 400 mg (4.5 ⁇ 10 ⁇ 4 " mole) of the tetrapeptide are deprotected. Once deprotection is complete, this tetrapeptide is dissolved in 15 ml of dichloromethane in a 50 ml monocol flask. 219 mg (4.5.10 " mole, leq) of Boc Arg (Mtr) OH and 188 mg (5.85.10 " 4 mole, l, 3eq) of TBTU are added. takes place at room temperature under nitrogen flow, protected from light and is maintained at pH 8 with DIEA. After 16 hours, the reaction is complete (TLC).
- this molecule was tested on B16 melanoma cells, no toxicity could be measured up to concentrations greater than 100 ⁇ M.
- this molecule injected IV into a batch of mice carrying a melanoma accumulates in the stroma of the tumor and then diffuses slowly within the tumor (see Table 2)
