- a method of treating or preventing organ or tissue transplant rejection comprising administering to a subject a therapeutically effective amount of a crystalline salt of the invention.
- a method of treating or preventing an autoimmune disease or inflammatory condition comprising administering to a subject a therapeutically effective amount of a crystalline salt of the invention.
- a salt of the invention e.g. a crystalline salt of the invention, for use as a pharmaceutical.
- a pharmaceutical composition comprising a salt of the invention, e.g. a crystalline salt of the invention, and a pharmaceutically acceptable diluent or carrier.
- a salt of the invention e.g. a crystalline salt of the invention for the preparation of a medicament, e.g. in a method as disclosed above.
- a pharmaceutical combination comprising (a) a salt of the invention, e.g. a crystalline salt of the invention and (b) a second drug substance, said second drug substance being suitable for the prevention or treatment of a condition described above.
- a method as defined above comprising co-administration, e.g. concomitantly or in sequence, of (a) a crystalline salt of the invention and (b) a second drug substance, said second drug substance being suitable for the prevention or treatment of a condition described above.
- Micronized Compound A e.g. 2-amino-2-(2-(4-octylphenyl)ethyl]propane-1 ,3-diol hydrochloride salt (FTY720), is screened and 116.7 g of the screened compound is mixed with 9683 3 g of a microcrystaliine cellulose agent. The mixture is then milled in a Frewitt MGI device (Key International Inc. USA) using a 30 mesh screen. Magnesium stearate is screened using a 20 mesh screen and 200 g of the screened compound blended with the FTY720 mixture to produce a product composition,
- FTY720 2-amino-2-(2-(4-octylphenyl)ethyl]propane-1 ,3-diol hydrochloride salt
- the product composition is then compacted on a tablet press using a 7 mm die to form 120 mg tablets, each containing:
- Microcrystaliine cellulose e.g. Avicel PH 102 116.2 mg Magnesium stearate 2.4 mg Total 120 mg
- example 2 the process of example 1 is repeated except that the magnesium stearate is replaced by Cutina® (hydrogenated castor oil).
- Cutina® hydrogenated castor oil
- the tartrate salt was then analysed by X-ray powder diffraction (XRPD).
- XRPD X-ray powder diffraction
- X-ray powder diagrams were recorded between 2o and 35o (2 theta) with Cu Ka radiation using a Scintag X1 diffraction system.
- Temperature variable and humidity variable XRPD was performed using the Scintag XDS 2000 system equipped with a temperature and humidity control unit.
- FTY720 free base (1.63 mrnot) was dissolved in i-PrOH (6 ml) at 82 oC. Then a solution of malonic acid (0.815 mmol) in i-PrOH (1 ml) was added at 82 oC.. Immediately after addition the product started to crystallize out. The suspension was cooled to room temperature. The product was collected by filtration and was washed with i-PrOH (2 ml). After drying at 50 °C the product was obtained as white crystals in 92.3% yield.
- FTY720 free base (1.63mmol) was dissolved in i-PrOH (6ml) at 82oC.. Then a solution of acetic acid (1.79eq) in i-PrOH ( 1 ml) was added at 82 oC.. The clear solution was cooled to room temperature, whereupon the product crystallized out. The resulting suspension was stirred for additional 15 minutes, the product was collected by filtration and was washed with i-PrOH (4ml). After drying at 50°C the crude product was obtained as white crystals in 83% yield. The product was recrystallized from a mixture of i-PrOH / acetic acid in 90.6% yield.
- FTY720 free base (2.27mmol) was dissolved in ethyl acetate (16ml) at 88-90 oC. Then a solution of acetic acid (2.5eq) in ethyl acetate (3ml) was added at 75oC 1 . whereupon the product started to crystallize out immediately after addition. The resulting suspension was cooled to room temperature. The product was collected by filtration and was washed with ethyl acetate (2ml). After drying at 50 oC. the product was obtained as white crystals in 99.4% yield.
- FTY720 free base (1.63mmol) was dissolved in ⁇ -PrOH (6ml) at 82 oC. Then a solution of propionic acid (1.79eq) in i-PrOH (1ml) was added at 82oC. The clear solution was cooled to room temperature, whereupon the product crystallized out. The resulting suspension was stirred for additional 15 minutes, the product was collected by filtration and was washed with i-PrOM (2ml). After drying at 50oC the crude product was obtained as white crystals in 68% yield. The product was recrystallized from a mixture of i-PrOH / propionic acid in 90.6% yield.
