Description

Stilbene derivative and be used for combination and the purposes of imaging amyloid plaques
Background of invention
Invention field
The present invention relates to new bioactive compound, use the method for radio-labelled compound diagnosing image and prepare the method for radio-labelled compound.
Background technology
Alzheimer (AD) is a kind of progressive neurodegenerative disorders, it is characterized in that cognitive decline, the irreversible loss of memory, disorientation and aphasis.The postmortem of AD brain section shows in a large number the senile plaque (SP) that is made of amyloid-β (A β) peptide and many neurofibrillary tangleses that is formed by the filament of hyperphosphorylation tau protein (NFT), and (recent summary is quoted as proof referring to Ginsberg with other, S.D. wait the people, " Molecular Pathology of Alzheimer ' s Disease and Related Disorders; " inCerebral Cortex:Neurodegenerative and Age-related Changes in Structureand Function of Cerebral Cortex, Kluwer Academic/Plenum, NY (1999), pp.603-654; Vogelsberg-Ragaglia, people such as V., " Cell Biology of Tau and CytoskeletalPathology in Alzheimer ' s Disease, " Alzheimer ' s Disease, Lippincot, Williams﹠amp; Wilkins, Philadelphia, PA (1999), pp.359-372).
Amyloidosis is to be characterised in that the disease of various insoluble fibrins (fibrillar protein) in the patient tissue inner accumulated.The following formation of amyloid beta deposition thing (amyloid pdeposit): amyloid aggregation, aggregation and/or amyloid further make up then.Amyloid-beta (A β) peptide aggregation body in brain formation and to gather be that AD takes place and the key factor of development.
Except the effect of amyloid beta deposition thing in Alzheimer, confirmed in such as following disease, to exist the amyloid beta deposition thing: Mediterranean fruit fly, Mu-Wei syndrome, idiopathetic myeloma, the amyloid polyneuropathy, the amyloid cardiomyopathy, the senile amyloidosis of general, the amyloid polyneuropathy, hereditary cerebral hemorrhage with amyloidosis, mongolism, itch, creutzfeldt-jakob disease, kuru, Ge-Shi-Sha syndrome, thyroid medullary carcinoma, isolated atrial amyloid (isolated atrial amyloid), β in the dialysis patient 2β in-microglobulin amyloid, occlusion body myositis, the muscular atrophy diseases 2-amyloid beta deposition thing and islets of langerhans type ii diabetes insulinoma.
Amyloid peptide A β 1-40With A β 1-42Fibrous aggregation be to be derived from the main metabolic peptide (Xia, people such as W., J.Proc.Natl.Acad.Sci U.S.A.97:9299-9304 (2000)) that sees the amyloid precursor protein in AD patient's senile plaque and the cerebrovascular amyloid beta deposition thing.Treat this disease target prevent and reverse A β speckle form (Selkoe, D.J.JAMA 283:1615-1617 (2000); Wolfe, people such as M.S., J.Med.Chem.41:6-9 (1998); Skovronsky, D.M. and Lee, V.M., Trends Pharmacol.Sci.21:161-163 (2000)).
Familial AD (FAD) is by A precursor protein (APP), presenilin 1 (PS1) and presenilin 2 (PS2) gene many places sudden change causing (Ginsberg, S.D. wait the people, " Molecular Pathology ofAlzheimer ' s Disease and Related Disorders; " in Cerebral Cortex:Neurodegenerative and Age-related Changes in Structure and Function ofCerebral Cortex, Kluwer Academic/Plenum, NY (1999), pp.603-654; Vogelsberg-Ragaglia, people such as V., " Cell Biology of Tau and CytoskeletalPathology in Alzheimer ' s Disease, " Alzheimer ' s Disease, Lippincot, Williams﹠amp; Wilkins, Philadelphia, PA (1999), pp.359-372).
Although also do not understand AD cutter system really fully, the pathogenic FAD sudden change of Yan Jiu all up to now all makes the generation of the A β peptide form of producing 42-43 stronger amino acid long of amyloid increase.Therefore, as if in FAD, the insufficiency of accommodation that A β produces is enough to induce the cascade that causes neurodegenerative incident at least.In fact, this amyloid cascade hypothesis prompting, the formation of extracellular fiber shape A beta peptide aggregation body in brain may be the critical events (Selkoe in the AD pathogenesis, D.J., " Biology of β-amyloid Precursor Protein and the Mechanism of Alzheimer ' sDisease; " Alzheimer ' s Disease, Lippincot Williams﹠amp; Wilkins, Philadelphia, PA (1999), pp.293-310; Selkoe, D.J., J.Am.Med.Assoc.283:1615-1617 (2000); Naslund, people such as J., J.Am.Med.Assoc.283:1571-1577 (2000); Golde, people such as T.E., Biochimica et Biophysica Acta 1502:172-187 (2000)).
Estimating at present and managing to suppress the interior fibrous A β generation of brain and reduce the whole bag of tricks that it gathers, as potential therapy (Skovronsky, D.M. and Lee, V.M., the Trends Pharmacol.Sci.21:161-163 (2000) of AD; Vassar, people such as R., Science 286:735-741 (1999); Wolfe, people such as M.S., J.Med.Chem.41:6-9 (1998); Moore, people such as C.L., J.Med.Chem.43:3434-3442 (2000); Findeis, M.A., Biochimica et Biophysica Acta 1502:76-84 (2000); Kuner, P., people such as Bohrmann, J.Biol.Chem.275:1673-1678 (2000)).Therefore, interesting for the part of exploitation specificity binding fiber shape A beta peptide aggregation body.Because extracellular SP is obtainable target,, and in the patient that research is lived, be used as probe to manifest the progressive deposition of A β in the AD amyloid generation (amyloidogenesis) so these new parts can be used as the in-vivo diagnostic instrument.
For this reason, reported several interesting method (Ashburn, people such as T.T., the Chem.Biol.3:351-358 (1996) that is used to develop fibrous A beta peptide aggregation body ligands specific; Han, people such as G., J.Am.Chem.Soc.118:4506-4507 (1996); Klunk, people such as W.E., Biol.Psychiatry 35:627 (1994); Klunk, people such as W.E., Neurobiol. Aging 16:541-548 (1995); Klunk, people such as W.E., Society for Neuroscience Abstract 23:1638 (1997); Mathis, people such as C.A., Proc.XIIth Intl.Symp.Radiopharm.Chem., Uppsala, Sweden:94-95 (1997); Lorenzo, A. and Yankner, B.A., Proc.Natl Acad.Sci.U.S.A.91:12243-12247 (1994); Zhen, people such as W., J.Med.Chem.42:2805-2815 (1999)).The most attracting method is based on highly conjugated chrysamine-G (CG) and Congo red (CR), the latter be used to dissect a body fluorescence staining (Ashburn, people such as T.T., the Chem.Biol.3:351-358 (1996) of SP and NFT in the AD brain section; Klunk, people such as W.E., J.Histochem.Cytochem.37:1273-1281 (1989)).3 of CR, CG and CG '-bromo-and 3 '-iodine derivant and the fibrous bonded inhibition constant of A beta peptide aggregation body (Ki) be respectively 2800,370,300 and 250nM (Mathis, C.A. wait the people, Proc.XIIth Intl.Symp.Radiopharm.Chem., Uppsala, Sweden:94-95 (1997)).Verified these chemical compounds optionally combine with A β (1-40) peptide aggregation body external, and in the AD brain section, optionally combine (Mathis with fibrous A β deposit, C.A. wait the people, Proc.XIIth Intl.Symp.Radiopharm.Chem., Uppsala, Sweden:94-95 (1997)).
A beta peptide aggregation body in the imaging brain has several potential benefits.By having the potential patient of excessive A β speckle in the identification brain, imaging technique can improve diagnosis; Therefore, Alzheimer may take place in them.It also can be used for monitoring this advancing of disease.When anti-speckle Drug therapy becomes can obtain the time, the A β speckle in the imaging brain can be monitor therapy provides basic instrument.Therefore, seek the simple noninvasive method that is used to detect with the interior amyloid beta deposition thing of quantitative patient forwardly always.At present, the detection of amyloid beta deposition thing comprises the histologic analysis of biopsy or obduction material.These two kinds of methods are defectiveness all.For example, obduction only can be used for postmortem diagnosis.
Because the amyloid beta deposition thing has many identical physical propertys (for example density and water content) with normal structure, so direct imaging is difficult in this sedimental body.With nuclear magnetic resonance (MRI) and the sedimental trial of computer assisted tomography art (CAT) imaging amyloid is disappointed, and they only detect the amyloid beta deposition thing under some advantage.In addition, provide certain selectivity with the effort of antibody, serum amyloid protein P albumen or other probe molecule labelling amyloid beta deposition thing in peripheral tissues, but poor organization internal imaging is provided.
The potential part that is used to detect the A beta peptide aggregation body in the brain alive must pass complete blood brain barrier.Therefore, relative less and have the lipophilic part of increase by using molecular size (comparing) with Congo red, can improve brain capture.Highly conjugated thioflavine (S and T) is used as the dyestuff (Elhaddaoui, people such as A., Biospectroscopy 1:351-356 (1995)) of A beta peptide aggregation body in the dyeing AD brain usually.
Reported the highly lipophilic tracer that is used in conjunction with (mainly forming) entanglement and (containing a aggregation) speckle by the tau protein of excessive phosphorylation [ 18F] FDDNP (people such as Shoghi-Jadid K, Am.J.Geriatr.Psychiatry.2002; 10:24-35).Use positron emission fault art (PET), reported in nine AD patients and seven contrast experimenters the deposit of this tracer-specific labelling speckle and entanglement (Nordberg A.Lancet Neurol.2004; 3:519-27).Use the new pharmacokinetic analysis program of prediction (call) institute interested brain district and the relative holdup time of pons, shown AD patient and contrasted difference between the experimenter.In AD patient, the holdup time is obviously higher relatively.This is complicated by following attractive discovery, promptly for external (in vitro) in conjunction with A β fibril and exsomatize (ex vivo) in conjunction with A β speckle, FDDNP and some NSAID compete (people such as Agdeppa ED, 2001; People such as Agdeppa ED, Neuroscience.2003; 117:723-30).
Reported in the recent period by use the benzothiazole anil [ 11C] 6-OH-BTA-1 (be also referred to as [ 11C] PIB) amyloid-beta (people such as Mathis CA, Curr.Pharm.Des.2004 in the imaging AD patient brain; 10:1469-92; People such as Mathis CA, Arch.Neurol.2005,62:196-200).With [ 18F] observed opposite among the FDDNP, [ 11C] 6-OH-BTA-1 combines with fibrous A β in vivo specifically.Diagnosis have the patient of mild AD show [ 11C] the remarkable delay of 6-OH-BTA-1 in cortex, known in AD cortex contain a large amount of amyloid beta deposition things.In AD patient's group, [ 11C] increase that is retained in the volume cortex of 6-OH-BTA-1 is the most remarkable.Also in calvarium portion, temporo and occipitalia cortex, reach and in striatum, observed huge increase.Relatively be not subjected in the zone (as subcortical white, pons and cerebellum) that amyloid beta deposition influences known, [ 11C] 6-OH-BTA-1 is trapped among AD patient and the contrast experimenter and equates.In the recent period, after deliberation another kind 11The A β speckle targeted probes of C labelling, promptly stilbene derivative [ 11C] SB-13.Use should [ 3H] binding affinity that this compound exhibits is fabulous can clearly be measured combination in the cortex grey matter in conjunction with prompting for SB-13 external, but really not so in the white matter of AD case (people such as Kung M-P, Brain Res.2004; 1025:98-105).In the cortex tissue homogenate of contrast brain, has low-down specificity combination.[ 3H] the Kd value of SB-13 in the homogenate of AD cortex be 2.4 ± 0.2nM.High binding ability and comparable value (14-45pmol/mg albumen) (the same) have been observed.As expected, slightly to moderate AD patients, [ 11C] SB-B demonstration in volume cortex (being speculated as the zone of containing high density A β speckle) is highly gathered, but really not so in the contrast experimenter of age-matched (people such as VerhoeffNP, Am.J.Geriatr.Psychiatry.2004; 12:584-95).
The Noninvasive technology that is used for amyloid beta deposition thing in imaging and the quantitative patient can be useful.In addition, suppressing amyloid aggregation forms the chemical compound of amyloid beta deposition thing and is used for determining that the method for the ability of chemical compound inhibition amyloid aggregation can be useful.
