Another object of the invention is to provide new salts and crystalline salt forms of the compound 3-Z-[1-(4-(N-((4-methyl-piperazin-1-yl)-methylcarbonyl)-N-methyl-amino)-anilino)-1-phenyl-methylene]-6-methoxycarbonyl-2-indolinone as such which are characterized by unexpected, new pharmacological properties.
The invention relates to a process for the preparation of the new salts and crystalline salt forms of the compounds of formula (I), optionally in the form of the individual optical isomers, mixtures of the individual enantiomers or racemates, and optionally to the hydrates and/or solvates thereof.
Process for the Preparation of the Salts
In the process according to the invention the free base of the compound of formula (I) is dissolved in a suitable solvent, such as 2,2,2-trifluoro-ethanol. The acid used for the crystallization is dissolved as well in a suitable solvent, such as 2,2,2-trifluoroethanol/water (50:50) or water (depending on the acid). The free base of the compound of formula (I) is then mixed with the acid at a predetermined base/acid molar ratio, which is selected from 1:1 or 2:1 depending on the acid. Then, the solvent is evaporated under reduced pressure. After evaporation of the solvent has occurred, a suitable crystallization solvent is added to the reaction mixture, and the reaction mixture is slowly heated up to 50° C. Suitable solvents for the crystallization are tetrahydrofurane, dichloromethane, water, methanol, n-butylacetate, 1,2-dimethoxyethane, 2,2,2-trifluoroethanol (TFE)/water=8:2, acetone/dimethylsulfoxide (DMSO)=8:2, chloroform, acetonitrile, ethanol, 1-methyl-2-pyrrolidinone (NMP)/water=80:20, propyl acetate, tert. butanol, 1,4-dioxane, ethyl acetate, propionitrile, di-isopropyl ether, tert. butylethyl ether, ethanol/water=80:20, nitrobenzene, cyclohexanone, ethyl phenyl ether, 2-nitropropane, tert. butylmethyl ether and isobutanol. After staying for about 30 minutes at 50° C., the reaction mixture is slowly cooled down to a suitable crystallization temperature, which is for example between 20° C. or 3° C. The reaction mixture stays at this temperature until enough crystals are formed, which can then be collected, for example by filtration.
The process is illustrated by the following example of manufacturing process of the salts and crystalline salt forms, as can be done in parallel in 96 well assay plates (maximum volume of each well is about 200 μl).
Approximately 1 g of the free base of the compound of formula (I) is dissolved in 10 ml of 2,2,2-trifluoroethanol. The acids used to prepare the salts are dissolved in 2,2,2-trifluoroethanol/water (50:50) or just in water as far as the L-aspartic acid is concerned. Each well of the 96 well plates is loaded with the free base of the compound of formula (I) as dissolved in 2,2,2-trifluoroethanol and with the acid as dissolved in the mixture of 2,2,2-trifluoroethanol/water (50:50) or just in water as far as the L-aspartic acid is concerned, such that the molar ratio of the compound of formula (I) to the respective acid is set according to the information given in Table 1 under “ratio base/acid”. The 96 well plates are then placed in a vacuum chamber (1 kPa) at room temperature for 24 h in order to evaporate the solvent. Afterwards, different solvents are added in each well according to the information given in Table 1 under “crystallization solvent”, and the well plates are sealed and heated up to 50° C. at a heating rate of approx. 5° C./min. The plate stays then for an additional 30 minutes at 50° C. Afterwards, the plate is cooled at a cooling rate of 5° C./h to a final temperature of 3 or 20° C. according to the information given in Table 1 under “Tfinal[° C.]”. At this temperature, the plates remain for a holding time of 24 h. The plates are then opened and the solids are collected by filtration.
A preferred embodiment according to the invention thus relates to the preparation of the new salts and crystalline salt forms of the compound in accordance with formula (I) as specified hereinbefore.
In another embodiment, the invention relates to solutions containing the compound of formula (I) dissolved or suspended, preferably dissolved in a solvent. In a preferred embodiment, the solvent is an alcohol, preferably 2,2,2-trifluoro-ethanol.
In particular, the invention relates to specific crystalline forms of the compound of formula (I), which are discussed and characterized in detail below.
Analytical Methods for the Characterization of the Salts
The harvested crystals may be characterized by X-ray powder diffraction and thermal analysis (DSC and in some cases also TGA). If suitable single crystals grow, single crystal X-ray structure analysis may be performed. The following equipment was used to characterize the crystalline salts forms.
XRPD patterns were obtained using a high throughput XRPD set-up. The plates were mounted on a Bruker GADDS diffractometer equipped with a Hi-Star area detector. The diffractometer was calibrated using Silver Behenate for the long d-spacings and corundum for the short d-spacings.
The data collection was carried out at room temperature using monochromatic CuKα radiation in the region of 2Θ between 1.5 and 41.5°. The diffraction pattern of each well was collected with an exposure time of 3-4 minutes.
Suitable single crystals were selected and glued to a glass fibre, which is mounted on a X-ray diffraction goniometer. X-ray diffraction data were collected for the mounted crystals at a temperature of 233 K using a KappaCCD system and MoKα radiation generated by a FR590 X-ray generator (Bruker Nonius Delft, The Netherlands). Unit-cell parameters and crystal structure were determined and refined using the software package maXus (Mackay et al., 1997).
Melting properties were obtained from differential scanning calorimetry (=DSC) thermograms recorded on a DSC822e (Mettler-Toledo GmbH, Switzerland). The DSC822e was calibrated for temperature and enthalpy with a small piece of indium (Tfus=156.6° C., ΔHfus=28.45 J/g). Samples were sealed in standard 40 μl aluminium pans and heated in the DSC from 25 to 300° C. with a heating rate of 20° C./min. Dry nitrogen gas was used to purge the DSC equipment during measurements at a flow rate of 50 ml/min.
The mass loss due to solvent or water loss from the crystals was determined by thermo gravimetric analysis (=TGA). During heating of a sample in a TGA/SDTA851e (Mettler-Toledo GmbH, Switzerland) the weight of the sample was monitored resulting in a weight vs. temperature curve. The TGA/SDTA851e was calibrated for temperature with indium and aluminium. Samples were weighed in 100 μl corundum crucibles and heated in the TGA from 25 to 300° C. with a heating rate of 20° C./min. Dry nitrogen gas was used for purging.
The results of the characterization of the new salt forms of the compound of formula (I) are shown below in Table 2. In this table, reference is made to Tables 3.1 to 3.20, which shows the single crystal data of the salt forms, and to FIGS.

Thus, the present invention further relates to the use of the salts and crystal salt forms of the compound of above formula (I) for the preparation of a medicament for the treatment or prevention of the above-mentioned fibrotic diseases.
Within the meaning of the present invention, the treatment of the diseases may also be via simultaneous, separate or sequential co-administration of effective amounts of one or more salts and crystal salt forms of the compound of formula (I) in accordance with the present invention and at least a further chemotherapeutic or naturally occurring, semi-synthetic or synthetic therapeutic agent, in the form of a combined preparation, which if necessary may optionally be adapted for a co-treatment with radiotherapy or radio-immunotherapy.
The present invention also relates to a process for the treatment of the above-mentioned diseases, characterized in that one or more of the above-mentioned salts or crystal salt forms of the compound of formula (I) are administered in therapeutically effective amounts to a patient in need thereof.
The present invention further relates to processes for the treatment of the aforementioned diseases, characterized in that one or more of the above-mentioned salts or crystal salt forms of the compound of formula (I) are administered once or several times a day or once or several times a week in therapeutically effective amounts.
The present invention also relates to pharmaceutical compositions comprising the above-mentioned salts or crystalline salt forms.
In the treatment of the aforementioned diseases, the physicochemical properties of a drug substance may influence decisively stability, usefulness and efficacy of the formulation. In this respect the salts or crystal salt forms of the compound of formula (I) in accordance with the present invention show advantageous properties not yet disclosed in the art.
Suitable preparations for the pharmaceutical compositions in accordance with the present invention include for example tablets, capsules, suppositories, solutions,—particularly solutions for injection (s.c., i.v., i.m.) and infusion—elixirs, emulsions or dispersible powders. The proportion of the pharmaceutically active compound(s) should be in the range from 0.01 to 90 wt.-%, preferably 0.1 to 50 wt.-% of the composition as a whole, i.e. in amounts which are sufficient to achieve the dosage necessary to achieve a therapeutic effect. If necessary the doses specified may be given several times a day.
Suitable tablets may be obtained, for example, by mixing the active substance(s) with known excipients, for example inert diluents such as calcium carbonate, calcium phosphate or lactose, disintegrants such as maize starch or alginic acid, binders such as starch or gelatine, lubricants such as magnesium stearate or talc and/or agents for delaying release, such as carboxymethyl cellulose, cellulose acetate phthalate, or polyvinyl acetate. The tablets may also comprise several layers.
Coated tablets may be prepared accordingly by coating cores produced analogously to the tablets with substances normally used for tablet coatings, for example collidone or shellac, gum arabic, talc, titanium dioxide or sugar. To achieve delayed release or prevent incompatibilities the core may also consist of a number of layers. Similarly the tablet coating may consist of a number or layers to achieve delayed release, possibly using the excipients mentioned above for the tablets.
Syrups or elixirs containing the active substances or combinations thereof according to the invention may additionally contain a sweetener such as saccharine, cyclamate, glycerol or sugar and a flavour enhancer, e.g. a flavouring such as vanillin or orange extract. They may also contain suspension adjuvants or thickeners such as sodium carboxymethyl cellulose, wetting agents such as, for example, condensation products of fatty alcohols with ethylene oxide, or preservatives such as p-hydroxybenzoates.
Solutions for injection and infusion are prepared in the usual way, e.g. with the addition of isotonic agents, preservatives such as p-hydroxybenzoates, or stabilisers such as alkali metal salts of ethylenediamine tetraacetic acid, optionally using emulsifiers and/or dispersants, whilst if water is used as the diluent, for example, organic solvents may optionally be used as solvating agents or dissolving aids, and transferred into injection vials or ampoules or infusion bottles.
Capsules containing one or more active substances or combinations of active substances may for example be prepared by mixing the active substances with inert carriers such as lactose or sorbitol and packing them into gelatine capsules.
Suitable suppositories may be made for example by mixing with carriers provided for this purpose, such as neutral fats or polyethyleneglycol or the derivatives thereof.
Excipients which may be used include, for example, water, pharmaceutically acceptable organic solvents such as paraffins (e.g. petroleum fractions), vegetable oils (e.g. groundnut or sesame oil), mono- or polyfunctional alcohols (e.g. ethanol or glycerol), carriers such as e.g. natural mineral powders (e.g. kaolins, clays, talc, chalk), synthetic mineral powders (e.g. highly dispersed silicic acid and silicates), sugars (e.g. cane sugar, lactose and glucose) emulsifiers (e.g. lignin, spent sulphite liquors, methylcellulose, starch and polyvinylpyrrolidone) and lubricants (e.g. magnesium stearate, talc, stearic acid and sodium lauryl sulphate).
The preparations are administered by the usual methods, preferably by oral route, by injection or transdermally. For oral administration the tablets may of course contain, apart from the abovementioned carriers, additives such as sodium citrate, calcium carbonate and dicalcium phosphate together with various additives such as starch, preferably potato starch, gelatine and the like. Moreover, lubricants such as magnesium stearate, sodium lauryl sulphate and talc may be used at the same time for the tabletting process. In the case of aqueous suspensions the active substances may be combined with various flavour enhancers or colourings in addition to the excipients mentioned above.
For parenteral use, solutions of the active substances with suitable liquid carriers may be used.
The dosage for intravenous use is from 1-1000 mg per hour, preferably between 5 and 500 mg per hour.
However, it may sometimes be necessary to depart from the amounts specified, depending on the body weight, the route of administration, the individual response to the drug, the nature of its formulation and the time or interval over which the drug is administered. Thus, in some cases it may be sufficient to use less than the minimum dose given above, whereas in other cases the upper limit may have to be exceeded. When administering large amounts it may be advisable to divide them up into a number of smaller doses spread over the day.
The following examples of pharmaceutical formulations illustrate the present invention without representing a limitation of its scope.
1. Coated tablet containing 75 mg of active substance
2. Tablet containing 100 mg of active substance
