Definitions
- the invention relates to novel linear or cyclic ammo-phospho ⁇ ates and their use as pH markers in 31 NMR spectroscopy More generally, the invention relates to the use of amino phosphonate derivatives as pH markers in spectroscopy NMR Phosphorus 31 NMR spectroscopy has proven to be an effective means for the measurement, in vivo, of extra- and intracellular pH
- the advantage of this method is that it does not disturb the medium at all on which the measurement is carried out, an essential condition for an in vivo measurement.
- a compound can be used as a pH marker when the numerical value of the chemical shift of the resonance peak obtained by NMR of the
- 31 P varies as a function of the pH of the medium into which the compound has been introduced.
- the difficulty consists in developing the ideal, non-toxic compound, which can function as a pH marker in a wide pH range, with good sensitivity.
- An additional requirement is that the measurement must be little, if at all, affected by the other constituents of the physiological medium and react only to a variation, even a very small one, of the pH.
- the level of Pi is generally low in the cell and varies with the metabolic state of the cell, - the lack of sensitivity of this compound does not make it possible to differentiate between the intra and extra cellular pH
- REPLACEMENT SHOE (RULE 26) 2 permeability to cell membranes in the case of the tumor cell line studied
- Phenylphosphonate is another marker of extracellular pH (cf. Circulation Research, vol 60, n ° 4, 1987, 472-477)
- the disadvantage of this compound is that the chemical displacement of 31 P is influenced by the presence of specific ions in the measurement medium
- the American Physiological Society, 1994, C195-C203 also points out the possibility of using 3-aminopropylphosphonate as an indicator of extracellular pH
- the present inventors have discovered a family of molecules, namely linear or cyclic amino-phosphonates, which are particularly advantageous insofar as they lead to improved sensitivity of pH measurement and where they make it possible to cover a whole range of pH different according to the substituents, thus making it possible to have an important precision on the measurement at more acidic or more basic pH These molecules are moreover not very toxic

- the reaction medium is stirred for 5 hours at room temperature and then poured onto a mixture of ice (300 g) and 32% ammonia (300 ml).
- the aqueous phase is extracted with dichloromethane (4 times 100 ml) and the latter is evaporated under reduced pressure to obtain a yellow oil.
- the oil is dissolved in 100 ml of dichloromethane, 200 ml of water are added and then hydrochloric acid 37% up to pH 1.
- the aqueous phase is washed with dichloromethane (4 times 50 ml) Soda and sodium carbonate are added to pH 10 and the aqueous phase is extracted with dichloromethane (4 50 ml).
- the organic phase is dried over sodium sulfate, filtered and then evaporated under reduced pressure to obtain the gem-bisphophonate.
- the reaction mixture is treated with a 0.1N hydrochloric acid solution until a pH 1 is obtained.
- the aqueous phase thus obtained is treated with a sodium hydroxide solution until a pH 8 is obtained.
- the treatment is terminated by addition of Na 2 CO 3 then saturated with NaCl It is extracted again with dichloromethane (4 x 30 ml)
- the organic phase is dried over MgSO 4 After evaporation of the solvents under reduced pressure, 9.8 g of crude product are obtained (yield 45%) in the form of a yellow oil
- the phosphite is evaporated under reduced pressure
- the pyrrolidine is purified by chromatography on silica with the eluent acetone / pentane (1/3) with 60% yield 31 P (C 6 D 6 ) ⁇ 26.9 ppm
- T ⁇ ethyl phosphite (23 g, 0.14 mole) and N-tertiobutylformamide (7.5 g, 0.073 mole) are placed in a 250 ml two-necked flask.
- the compounds are mixed at room temperature for a few minutes.
- an ice bath with salt and 23 g of POCI 3 (i.e. 0.15 mole) are added at -5 ° C. The addition lasts 1 hour Then the reaction is allowed to stir at ambient temperature for 5 hours The solution is gradually colors o in orange
- the crude mixture is then poured into a beaker containing 150 g of ice and 150 ml of 32% ammonia solution.
