Description

The polymorphic form of N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide

Background of invention

Invention field

The present invention relates to the crystalline form or the polymorphic form of N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide; And the method for preparing them, comprise their pharmaceutical composition and use the method for their treatments.

Related background art

Heteromorphism representes that material exists more than a kind of crystalline structure.Chemical substance can have profound influence to physico-chemical property, storage period, solubleness, preparation nature and the working properties of medicine to modify the crystalline ability more than a kind of crystal.In addition, the effect of medicine can receive the heteromorphism influence of drug molecule.Different polymorphic forms can have differing absorption speed in vivo, causes the lower or higher BA that has than expection.Under extreme case, undesirable polymorphic form even can show toxicity.In the preparation process, form unknown polymorphic form and can have tremendous influence.

Therefore, listing has conclusive benefit for new drug for understanding and control heteromorphism.At first also the most important thing is, medicament prodn is predicted that any possible polymorphic form can be used for reducing at medication preparation or storage process by other polymorphic form contamination of heavy.In some cases, can not control pollution and have life-threatening consequence.The unwanted polymorphic form of crystallization means the production shut-down period of several weeks even several months in the preparation process, and scientist finds and corrects the reason of new crystalline form or carries out another and take turns test to obtain the approval of new crystalline form.

Secondly, in some cases, understand the sort of crystalline structure and be and possible make the investigator can compound be expected the character optimization, described character is solubleness, preparation nature, working properties and storage period for example.The medicine that can mean preparation in these factors of early stage understanding of new drug development more effectively, more stable or more cheap.

Compound N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide (alternatively, N-hydroxyl-3-(4-{ [2-(2-Methyl-1H-indole-3-yl)-ethylamino]-methyl }-phenyl)-acrylic amide) has formula (I):

Like what describe among the WO 02/22577.This compound has valuable pharmacological character; Therefore, it can be used to treat the histone deacetylase activity is suppressed to have the disease of response as for example histone deacetylase inhibitors.Knowledge to the potential polymorphic form of N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide is used to develop suitable formulation, does not have comparability between criticizing and criticizing because when clinical or stability study, can not use a definite formulation that single polymorphic form possibly cause that institute uses or studies.Importantly, polymorphic form can repeat to prepare and in the formulation of exploitation, remain unchanged in long-time during selection.Also hope to have the method for preparing high purity N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide, because the existence of impurity possibly produce undesirable toxicology effect.

The information that WO 02/22577 does not provide the possible crystal of relevant N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide to modify at all.Have surprisingly been found that at present the different crystal modification (polymorphic form of new N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide) with hereinafter characteristic can be through the special method condition preparation of selecting, for example selective solvent system, crystallization time length etc.

Under 4 ℃, the salt formation reaction in Virahol and acetone produces the DL-lactic acid salt of stoichiometry (1:1), monohydrate.This salt is crystalline, is higher than to begin dehydration under 77 ℃ and be higher than 150 ℃ to decompose down.

Embodiment 21

Anhydrous L-(+)-Lactated formation

According to the method for describing among the embodiment 19; N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide free alkali (20.0g) is handled with L-(+)-lactic acid (6.8g); Obtain crystalline N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide L-(+)-lactic acid salt, anhydrous form.Fusing point takes place with decomposing under 184.7 ℃ simultaneously.XRPD figure is shown in Figure 13 D (2 θ=9.9,11.4,13.8,18.1,18.5,19.7,20.2,21.6,25.2,29.9).

Embodiment 22

Anhydrous D-(-)-Lactated formation

According to the method for describing among the embodiment 19; N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide free alkali (20.0g) is handled with D-(-)-lactic acid (6.8g); Obtain crystalline N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide D-(-)-lactic acid salt, anhydrous form.Fusing point takes place with decomposing under 184.1 ℃ simultaneously.XRPD figure is shown in Figure 13 E (2 θ=9.9,11.4,13.8,18.1,18.5,19.7,20.2,21.6,25.2).

Morphological character

Absorption-desorption attaches thermo-isopleth and equals a record through VTI humidity sky.At first the salt with N-hydroxyl-3-[4-[[[2-(2-Methyl-1H-indole-3-yl) ethyl] amino] methyl] phenyl]-2E-2-acrylic amide carries out (25 ℃ of drying step; Relative humidity is less than 2%; 2 hours), to carry out absorption-desorption then and attach-the absorption order, each RH% step kept 3 hours.Free alkali was kept several hours less than 2% time in relative humidity, and therefore dehydration fully after drying step.Only provided the data of first sorption cycle in the table, therefore, in all cases, two sorption cycle are very similar.

The present invention describes as above with reference to its special embodiment, and it is obvious that, can carry out many changes, modification and variation and can not break away from this paper invention disclosed notion.Therefore, be intended to comprise all spirit and the change in the wide region, modification and variations in accompanying claims.All patented claims that this paper quotes, patent and other publication are incorporated this paper into as a reference with its integral body.
