MENETELMÄ LÄÄKEAINEENA KÄYTTÖKELPOISTEN PIPERIDIINIJOHDAN
NAISTEN VALMISTAMISEKSI
Teollisen hyväksikäytön alue Tämä keksintö koskee menetelmää piperidiinijohdannaisen, valmistamiseksi joilla on erinomaisia lääkevaikutuksia.
Tekniikan taso
On ehdotettu erilaisia lääkkeitä aivoverisuonisairauksiin. On käytetty esimerkiksi aivoverisuonia laajentavia lääkkeitä ja aivojen aineenvaihdunnan aktivoijia. Tähän mennessä ei kuitenkaan ole ehdotettu mitään lääkettä, joka on erittäin tehokas. Nykyään ei ole mitään lääkettä, joka vaikuttaa erityisesti aivoverisuonidementiaan ja älyllisen toiminnan sairauksiin aivoverisuonisairauksista johtuvien oireiden joukossa.
Keksinnön tarkoitus
Laajojen tutkimusten jälkeen, jotka tehtiin uuden yhdisteen löytämiseksi, joka on tehokas hoidettaessa erilaisia oireita, jotka johtuvat aivoverisuonisairauksista, erityisesti mielen oireita, pitkänä ajanjaksona edellä mainituissa olosuhteissa, ovat keksijät löytäneet melko tehokkaita yhdisteitä. Tämä keksintö on täydennetty tämän löydön pohjalta.
Siksi tämän keksinnön tarkoitus on tarjota käyttöön menetelmä piperidiinijohdannaisten ja niiden farmakologisesti sopivien suolojen valmistamiseksi, jotka ovat tehokkaita hoidettaessa aivoverisuonisairauksia, kuten aivohalvaus, halvaus, infarkti ja arterioskleroosi ja mielen oireet, jotka johtuvat multippeli-infarktidementiasta .
Tämän keksinnön mukaisella menetelmällä valmistetaan yleisen kaavan (I) mukaisia piperidiinijohdannaisia tai niiden farma kologisesti sopivia suoloja: 2 90533 o ^j^-X-(CH2)n-/^^C ~CVR (I) jossa X on -CO- tai -CHOH-, n on kokoluku 0-4, R on vety, halogeeni tai Ci-Ce-alkyyli, ja keksinnölle on tunnusomaista se, mitä on esitetty patenttivaatimusten tunnusmerkkiosassa.
Alempi alkyyliryhmä Rsn määritelmässä sisältää esimerkiksi suoraketjuiset tai haarautuneet alkyyliryhmät, joissa on 1-6 hiiliatomia, kuten metyyli-, etyyli-, n-propyyli, n-butyyli, isopropyyli-, isobutyyli-, 1-metyylipropyyli-, tert.butyyli-, n-pentyyli-, 1-etyylipropyyli-, isoamyyli- ja n-heksyyliryh-mät. Näiden joukossa metyyli-ja etyyliryhmät ovat edullisimpia .
Halogeeniatomeita ovat fluori-, kloori-, bromi- ja jodiatom- it.
Farmakologisesti sopivia suoloja ovat tavalliset myrkyttömät suolat, esimerkiksi epäorgaaniset happosuolat, kuten hydro-kloridit, hydrobromidit, sulfaatit ja fosfaatit; orgaaniset happosuolat, kuten asetaatit, maleaatit, tartraatit, metaan-isulfonaatit, benseenisulfonaatit ja tolueenisulfonaatit; ja aminohapposuolat, kuten arginiinisuolat, aspartaatit ja glu-tamaatit.
Valmistusmenetelmät Tämän keksinnön yhdisteet voidaan valmistaa erilaisilla menetelmillä. Tyypillinen esimerkki näistä menetelmistä on; 3 90533 ^ X (CH2) n^-CHj-Ha 1 (II) + 0 II (111) .^!ο* (I) jossa Hal esittää halogeeniatomia ja X, n ja R ovat kuten yllä on määritelty.
Nimittäin yleisen kaavan (II) mukaisen halogenidin annetaan reagoida yleisen kaavan (III) mukaisen yhdisteen kanssa, jolloin saadaan haluttu yleisen kaavan (I) mukainen yhdiste.
Dehydrohalogenointireaktio suoritetaan kuumentamalla tavallisella tavalla käyttämättä liuotinta tai orgaanisessa liuotti-messa, joka on inertti reaktiolle ja joka on valittu ryhmästä, johon kuuluvat alkoholiliuottimet, kuten metanoli, etanoli ja butanoli, bentseeni, tolueeni, ksyleeni, tetrahydro-furaani, kloroformi, hiilitetrakloridi ja dimetyyliformamidi. Edullisia tuloksia saadaan, kun reaktio suoritetaan epäorgaanisen suolan, kuten natriumvetykarbonaatin, kaliumkarbonaatin, natriumkarbonaatin tai natriumhydroksidin, tai orgaanisen emäksen, kuten trietyyliamiinin, pyridiinin, pyrimidiinin tai dietyylianiliinin, läsnäollessa.
4 90533 Jäljessä kuvatuista farmakologisista kokeista ilmenee, että tämän keksinnön mukaisella menetelmällä valmistetuilla yhdisteillä on erinomaiset farmakologiset vaikutukset keskushermosto järjestelmään, erityisesti huomattava korjaava vaikutus iskeemisiin aivoverisuonisairauksiin. Sen vuoksi nämä yhdisteet ovat käyttökelpoisia lievittämään, parantamaan tai ehkäisemään mielen sairauksia, jotka johtuvat aivoverenkiertosairauksista, kuten aivohalvaus, halvaus, infarkti, arterioskleroosi ja dementiat, esim. multippeli infarktidementia.
Rottia käyttäen suoritetuissa myrkyllisyyskokeissa on havaittu, että tämän keksinnön mukaisella menetelmällä valmistetut yhdisteet ovat erittäin turvallisia ja siksi keksintö on hyvin arvokas myös tässä suhteessa.
Tämän keksinnön tyypillisten yhdisteiden myrkyllisyyskokeiden mukaan niiden LD50 oli 2000-4000 mg/kg (rotille oraalisesti annettuna).
Lääkkeenä käytettyinä tämän keksinnön mukaisella menetelmällä valmistetut yhdisteet annetaan joko oraalisesti tai parente-raalisesti. Mainittujen yhdisteiden annosta ei erityisesti ole rajoitettu, koska se vaihtelee riippuen oireista; potilaan iästä, sukupuolesta, ruumiinpainosta ja herkkyydestä; antoajasta ja väliajoista; lääkevalmisteen ominaisuuksista, koostumuksesta ja lajista; ja vaikuttavien aineosien vaihteluista. Tavallisesti annetaan noin 0,1-300 mg/päivä, edullisesti noin 1-100 mg/päivä yhdistettä 1-4 kertaa päivässä.
Tämän keksinnön mukaisella menetelmällä valmistettuja yhdisteitä käytetään lääkevalmisteen muodossa, kuten injektiona, peräpuikkona, kielenalustablettina, tablettina tai kapselina.
Injektion valmistuksessa pH-säätäjä, puskuri, suspendoiva aine, liuottaja, stabiloija, isotonisoija, säilöntäaine, jne. lisätään vaikuttavaan aineeseen muodostamaan suonensisäisen, ihonalaisen tai lihaksensisäisen injektion tavallisella menetelmällä. Tarpeen vaatiessa injektio voidaan pakastekuivata 11 5 90533 tavallisella menetelmällä.
Esimerkkejä suspendoivista aineista ovat metyyliselluloosa, Polysorvate 80, hydroksietyyliselluloosa, akaasia, tragakant-tikumijauhe, natriumkarboksimetyyliselluloosa ja polyoksiety-leenisorbitaanimonolauraatti.
Esimerkkejä liuottajista ovat polyoksietyleenikovetettu risiiniöljy, Polysorbaatti 80, nikotiiniamidi, polyoksietylee-nisorbitaanimonolauraatti, macrogol ja risiiniöljyn rasvahappojen etyyliesterit.
Esimerkkejä stabiloijista ovat natriumsulfiitti, natriumme-tasulfiitti ja eetteri. Esimerkkejä säilöntäaineista ovat metyylihydroksibentsoaatti, etyylihydroksibentsoaatti, sor-biinihappo, fenoli, kresoli ja kloorikresoli.
Esimerkit

Koe-esimerkki 1
Iskeemisten aivojen suojavaikutus ICR-hiirten (6-8 viikon ikäisten) molempien puolten yhteiset päävaltimot paljastettiin halotaanianestesiassa ja sidottiin. Näin käsitellyillä hiirillä oli halvausoireita, kuten hyppimistä, pyörimistä ja kouristusta ja melkein kaikki niistä kuolivat 24 h:n kuluessa.
Tämän keksinnön yhdistettä annettiin oraalisesti hiirille tuntia ennen sidontaa ja eloonjäämisaika (maksimi: 6 h) tutkittiin indeksinä iskeemisten aivojen suojavaikutuksesta. Tässä kokeessa yhdistettä 2 käytettiin 5 %:sena suspensiona akaasiassa ja vertailuryhmälle annettiin 5 % akaasialiuosta.
Tulokset on esitetty taulukossa 2. On ilmeistä, että tämän keksinnön yhdisteillä on elämää pidentävä vaikutus, kun taas vertailuryhmän keskimääräinen eloonjäämisaika oli 149,9 min.

Parannusvaikutus iskemian jälkeiseen oppimishäiriöön
Mongolian antilooppirottien (17-21 viikon ikäisten) molempien puolten yhteiset päävaltimot nipistettiin Skoville-pihdeillä ilman anestesiaa ja pihdit poistettiin 5 min kuluttua, jolloin saatiin aikaan lyhyt iskemiajakso. 24 tuntia pihtien poiston jälkeen näille eläimille annettiin opetus ja muisti-kokeet suoritettiin vielä 24 h:n kuluttua.
Oppimis- ja muistitoimintoja tutkittiin passiivisella välttä-miskokeella laitemuunnoksella, joka on esitetty julkaisussa Jarvik & Kopp, "Psychological Reports", 21, 221-224 (1967). Laitteessa on kaksi kammiota, s.o. hyvin valaistu kammio A ja pimeä kammio B. Kokeissa eläimet sijoitettiin hyvin valaistuun kammioon A ja sähkövirta (vaihtovirta, 1,6 mA) kohdistettiin sähköjohtoverkkoon pimeän kammion B lattialla 5 min ajaksi, kun ne astuivat kammioon B.
Seuraavana päivänä opetuksen saaneet eläimet pantiin kammioon A ja aika (latenssiaika), joka oli kulunut ennen kuin ne astuivat kammioon B, mitattiin. Yläraja latenssiajalle asetettiin 300 sekunniksi.
Yhdistettä 2 annettiin 5 % suspensiona akaasiassa oraalisesti tuntia ennen iskemian aiheuttamista. Vertailuryhmälle annettiin 5 % akaasialiuosta.
Tulokset on esitetty taulukossa 3. Normaalin (pseudo-operaa-tio)ryhmän keskimääräinen latenssiaika oli 246,5 s, ja vertailuryhmän niinkin lyhyt kuin 71,5 s. Niiden oppimis- ja muistitoiminnot nimittäin tuhottiin 5 min iskemialla. Kun tämän keksinnön yhdisteitä annettiin vertailuryhmälle, latenssiaika piteni jälleen, oppimishäiriö iskemian jälkeen nimittäin parantui.

Solujen suojaamisvaikutus iskemian jälkeiseltä häiriöltä
Mongolian antilooppirottien molempien puolten päävaltimot tukittiin aivoiskemian aiheuttamiseksi 5 minuutiksi. Tuloksena tästä hermosolut aivoturson CAI-alueella hävisivät laajalti Karino, T.s Brain Res., 239, 57-69 (1982) .
Tämän keksinnön yhdistettä 2 annettiin niille oraalisesti, samalla kun vertailuryhmälle annettiin 5 % akaasiasuspensi-ota. Tunnin kuluttua iskemia aiheutettiin 5 minuutiksi.
1: 13 90533
Viikon kuluttua eläin läpihuuhdeltiin ja fiksattiin 4 % neutraalilla formaliinilla transkardiaalisesti. Käsitelty näyte upotettiin parafiiniin ja leikattiin leikkeiden saamiseksi, joiden paksuus oli 3 μπι. Leikkeet värjättiin hematoksyliini-eosiinilla ja hermosolujen lukumäärä aivoturson CAI-alueella jokaisessa leikkeessä laskettiin.
Tulokset on esitetty taulukossa 4. Hermosolutiheys aivoturson CAI-alueella oli 287/mm normaalissa (pseudo-operaatio)ryhmässä ja vertailuryhmässä niinkin pieni kuin 21/mm. 5 minuutin iskemialla aiheutettiin vakava häviäminen. Toisaalta, kun annettiin tämän keksinnön yhdistettä 2, hermosolutiheys kas-voi todistaen sen vaikutuksen solujen suojaamisessa häiriöltä.
