Abstract
Crystalline forms of 4-[2-(4-methylphenylsulfanyl)-phenyl]piperidine and salts thereof are provided e.g. for the treatment of neuropathic pain.
Description
The pain sensation be than signal from bodily injury part to brain the direct transmission of special receptor more complicated, and the pain of wherein feeling is proportional to injury.Or rather, the infringement that the end is organized slightly and may cause the change of the nervus centralis structure that the pain sensation that influences pain sensitivity subsequently is related to the injury of nerve.This neuromechanism changes may cause that central nervous system is in sensitization aspect the reaction of longer destructive stimulus of time length, this may show as such as chronic pain, namely even at destructive stimulus stopped the back pain sensation still, or hyperpathia, namely increase the reaction that belongs to the stimulation of normal pain to a kind of.This point more mysterious and be " phantom limb syndrome " to one of play example, namely in the limbs before it cuts off the lasting pain of existence.About the nearest summary of nervus centralis structural modification and pain, see Melzack et al, Ann.N.Y.Acad.Sci., 933,157-174,2001.
Chronic pain, neuropathic pain for example shows to such an extent that be different from other type pain for example body pain or visceral pain.This pain often is described to thorn, burning, pinprick, fiber crops or cutter and cuts out.The common cause of neuropathic comprises alcoholism, amputation, and back, shank and hip problem, chemotherapy, diabetes, the human immunodeficiency virus, multiple sclerosis, spinal surgery and varicella zoster virus infect.
The nervus centralis of chronic pain part can explain chronic pain for example neuropathic how often to classical anodyne for example nonsteroidal anti-inflammatory agent (NSAIDS) and opium class anodyne poor response.It is the standard medication that the tricyclic antidepressant (TCA) of typical case's representative has become the treatment neuropathic with the amitriptyline, and its effect believes it is [the Clin.Ther. that carries matter and norepinephrine to carry the comprehensive restraining effect of matter to take place via to thrombotonin, 26,951-979,2004].More closely, there has been the people will have inhibiting so-called economic benefits and social benefits thymoleptic to be used for the treatment of neuropathic [Human Psychopharm., 19, S21-S25,2004] to thrombotonin and norepinephrine re-uptake clinically.The example of economic benefits and social benefits thymoleptic is Venlafaxine and duloxetine, and these class thymoleptic often abbreviate SNRI as.
Be used for about selective serotonin reuptake inhibitor (SSRI) neuropathic purposes data seldom, but it is generally acknowledged effect limited [Bas.Clin.Pharmacol., 96,399-409,2005].In fact, the someone supposes that the SSRI class itself is faint anti-nociceptive, but the hypothesis thrombotonin carries the restraining effect of matter to increase the antinociceptive effect that norepinephrine reuptake suppresses.This idea obtains the support of a 22 zooscopies and 5 human research's summary, these studies show that the SNRI class is compared with NRI excellent antinociceptive effect, and this is better than SSRI[Pain Med.4,310-316,2000].

Detailed description of the present invention
The present invention relates to be the compound I of crystallized form, i.e. 4-[2-(4-methylbenzene sulfenyl) phenyl] piperidines and pharmaceutical acceptable salt thereof, prerequisite is that described compound is not the salt acid salt.4-[2-(4-methylbenzene sulfenyl) phenyl] structure of piperidines is
The pharmacology performance of The compounds of this invention is set forth in an embodiment, but can be summarized as follows.This compound is the inhibitor of thrombotonin and norepinephrine reuptake; They suppress serotonin receptor 2A, 2C and 3; And they suppress the alpha-1 adrenergic acceptor.
In one embodiment, described pharmaceutical acceptable salt is the acid salt of non-toxic acid.Described salt comprises the salt of making from following organic acid: toxilic acid for example, fumaric acid, phenylformic acid, xitix, succsinic acid, oxalic acid, the ethanetetrayl Whitfield's ointment, methylsulfonic acid, ethionic acid, acetic acid, propionic acid, tartrate, Whitfield's ointment, citric acid, glyconic acid, lactic acid, oxysuccinic acid, propanedioic acid, amygdalic acid, styracin, citraconic acid, aspartic acid, stearic acid, palmitinic acid, methylene-succinic acid, oxyacetic acid, para-amino benzoic acid, L-glutamic acid, Phenylsulfonic acid, theophylline acetic acid, and 8-halo theophylline 8-bromine theophylline for example.Described salt also can for example Hydrogen bromide, sulfuric acid, thionamic acid, phosphoric acid and nitric acid be made from mineral acid.Other useful salt is listed in the table (table 1) of embodiment 1d.
In one embodiment, The compounds of this invention is that formula 1 compound is the HBr additive salt.
In one embodiment, The compounds of this invention is DL-lactic acid additive salt, 1:1 salt especially.
In one embodiment, The compounds of this invention is L-aspartic acid additive salt, 1:1 salt especially.
In one embodiment, The compounds of this invention is L-glutamic acid additive salt, 1:1 salt especially.
In one embodiment, The compounds of this invention is pentanedioic acid additive salt, 1:1 salt especially.
In one embodiment, The compounds of this invention is propanedioic acid additive salt, 1:1 salt especially, has been found that the latter exists with two kinds of polycrystalline modification α and β, and wherein β-formal cause solubleness is lower and it is believed that it is the most stable.
In one embodiment, The compounds of this invention is refining form." refining form " this term intention points out that this compound is gone up substantially and do not contain other compound or other form, i.e. the polymorphic of described compound is as the presumable polymorphic of this situation.
Per os formulation, especially tablet and capsule, because the easily thereby better conformability of administration, patient and doctor have a preference for often.For tablet and capsule, being preferably this effective constituent is crystallization.
Crystallization of the present invention can be used as solvate and exists, and namely solvent molecule constitutes the crystal of the part of its crystalline structure.This solvate can generate from water, and this solvate often is called hydrate in this case.Substituting, this solvate can for example ethanol, acetone or ethyl acetate generate from other solvent.The definite quantity of solvate is often different because of condition.For example, hydrate typically can rise or the dehydration with the humidity reduction with temperature.When condition or not or have only the compound of a little change when for example humidity changes, generally be considered as being more suitable in the medicine prescription.Be noted that the HBr additive salt does not generate hydrate when separating out precipitation from water, the compound as succinate, malate and tartrate acid salt is then right.
Some compounds are moisture absorptions, and namely they absorb water when being exposed to humidity.Water absorbability for will be with the medicine prescription, especially as the compound that tablet or capsule provide, be considered as a kind of undesirable performance to do Formulation Example.In one embodiment, the invention provides the low crystallization of water absorbability.
For the per os formulation of using crystallinity effective constituent, if described crystallization clearly defines, then also be useful.In this paper category, " clearly defining " this term refers to that especially stoichiometry clearly defines, and namely refers to into ratio between the salt ion and be the ratio between the small integer, for example 1:1,1:2,2:1,1:1:1 etc.In one embodiment, The compounds of this invention is the crystallization that clearly defines.
The solubleness of effective constituent also is significant for the selection of formulation, because it may have a direct impact bioavaliability.For the per os formulation, believe that generally the solubleness of effective constituent is more high more useful, because it has improved bioavaliability.Some patients for example gerontal patient's swallow tablet may have any problem, and a mouthful solution may be needing to avoid a kind of being suitable for of swallow tablet to substitute.For restricted entry drips the volume of solution, the high density that reaches effective constituent in this solution is necessary, and this requires the high-dissolvability of this compound again.As shown in table 3, DL-lactic acid, L-aspartic acid, L-glutamic acid, pentanedioic acid and propanedioic acid additive salt have especially high solubleness.
Crystallized form influences filtration and the processing characteristics of compound.Needle crystal tends to more be difficult to operation under production environment, become more difficult and time-consuming because filter.The definite crystallized form of a certain given salt may depend on that for example this salts out the condition of precipitation.HBr acid salt of the present invention is growth needle-like solvate crystals when separating out precipitation from ethanol, acetic acid and propyl alcohol, but the crystal of the non-hydrated form of the non-needle-like of growing when the HBr additive salt is separated out precipitation from water provides excellent strainability.
Table 3 has also been set forth crystallization pH, i.e. pH in this salt saturated solution.Why important this performance is, is because lay up period moisture can't be avoided forever fully, and the accumulation of moisture can cause in the tablet that comprises low crystallization pH salt or on pH reduce this and may shorten shelf-life.And then when tablet was made with wet granulation, the salt that crystallization pH is low may cause the processing unit corrosion.Data in the table 3 show that HBr, HCl and hexanodioic acid additive salt may be excellent at this on the one hand.

IASP (IASP) is defined as pain " unhappiness sensation and the emotional experience that interrelate with reality or potential tissue injury or describe with this type of infringement " (IASPClassification of Chronic Pain, 2
NdEdition, IASP Press (2002), 210).Although pain is always subjective, its reason or syndrome can be classified." neuropathic " is defined as " pain that primary injury or dysfunction cause or cause in the neural system " as a subclass by IASP.
The different subclass of neuropathic obtain IASP and admit that the example is:
Allodynia is defined as " pain that causes owing to a kind of stimulation that does not usually excite pain ".
Cusalgia is defined as " syndrome of hyperpathia, often concurrent vasorelaxation and sudomotor function obstacle and alteration in nutrition after a while after lasting Burning Pain, allodynia and the traumatic nerve injury ".
Oxypathy is defined as " susceptibility to stimulating of raising forecloses feeling ".
Neurodynia is defined as " one or more neural distributivity pain ".
● neuritis is defined as " inflammation that one or more are neural ".
● neuropathy, be defined as " nervous function disorder or pathological change: mononeuropathy in a kind of nerve, mononeuropathy multiplex in some nerves, if dispersivity with two-way then be polyneuropathy ".Neuropathy may with interrelate such as diabetes, be referred to as diabetic neuropathy in this case.
● hyperpathia is defined as " reaction to the stimulation that belongs to normal pain of raising ".
● hyperpathia is defined as " a kind of pain syndrome is characterized in that stimulation, the especially unusual pain reaction of repetitive stimulation, and the threshold value that improves ".
The stimulation that causes this neuropathic can be machinery or hot.
Unique pharmacology performance of The compounds of this invention makes it be applicable to other disease that treatment is direct not relevant with chronic pain.5-HT
2CAcceptor is positioned at such as on the dopaminergic neuron, and at this, activation discharges Dopamine HCL and produces the inhibition influence of strengthening, and 5-HT
2CAntagonistic will influence the raising of dopamine level.The data presentation that provides among the embodiment 2E, The compounds of this invention can bring the dose dependent of dopamine level outside the born of the same parents to improve really in brain.Under this background, can suppose 5-HT
2CAntagonistic is specially adapted to treat the dysthymia disorders [Psychopharmacol.Bull., 39,147-166,2006] that is difficult to the treatment of selective serotonin reuptake inhibitor.This hypothesis is supported in some clinical studyes, these studies show that, the combination of mirtazapine and SSRI is better than the patients with depression that SSRI is used for the treatment of does not separately have enough clinical responses (treatment-resistant dysthymia disorders, TRD or refractory depression disease) [Psychother.Psychosom., 75,139-153,2006].Mirtazapine also is a kind of 5-HT
2And 5-HT
3Antagonistic, this shows, has both serotonin reuptake and suppresses to use and 5-HT
