Menetelmä farmaseuttisesti käyttökelpoisen [R-(R*,R*)]-2-(4-f luorifenyyli) -/3,S-dihydroksi-5- (l-metyylietyyli) -3-fenyyli-4-[(fenyyliamino)karbonyyli]-lH-pyrroli-l-heptaa-nihapon ja sen farmaseuttisesti hyväksyttävien suolojen valmistamiseksi
Trans-(±)-5-(4-fluorifenyyli)-2-(l-metyylietyyli)-N,4-di-fenyyli-l-[2-tetrahydro-4-hydroksi-6-okso-2H-pyran-2-yy-li)etyyli]-lH-pyrroli-3-karboksamideja on esitetty US-pa-tentissa n:o 4,681,893 yhdisteinä, joita voidaan käyttää kolesteroli-biosynteesin inhibiittoreina. Siinä esitetyt yhdisteet käsittävät yleisesti 4-hydroksipyran-2-oneja ja niistä muodostettuja vastaavia avatun renkaan omaavia happoja.
Nyt on odottamatta todettu, että trans-5-(4-fluorifenyyli ) -2 - ( 1-metyy1ietyy1i)-N,4-difenyyli-1-(2-tetrahydro-4-hydr oks i- 6-okso-2H-pyran-2 -yy 1 i) etyyli ] - lij-pyrrol i-3 -kar-boksamidin avatun renkaan omaavan hapon R-muodon enantio-meeri, s.o. [R-(R*,R*) ]-2-(4-f luorifenyyli)-/3, δ-dihydrok-si-5-(l-metyylietyyli)-3-fenyyli-4-[(fenyyliamino)karbonyyli ]-lfi-pyrroli-l-heptaanihappo saa aikaan kolesterolin biosynteesin yllättävän inhibiition.
On tunnettua, että 3-hydroksi-3-metyyliglutaryyli-koent-: syymi A (HMG-CoA) esiintyy 3R-stereoisomeerinä. Lisäksi, kuten Stokker et ai. ovat osoittaneet 5-substituoitujen 3.5- dihydroksipentaanihappojen ryhmän tutkimuksessa artikkelissa "3-Hydroxy-3-methylglutaryl-Coenzyme A Reductase Inhibitors. 1. Structural Modification of 5-Substituted 3.5- Dihydroxypentanoic acids and Their Lactone Derivati- * ves" julkaisussa J. Med. Chem. 1985, 28, 347 - 358, olen naisesti koko biologinen aktiivisuus kuuluu positiivisesti kiertävän (E)-6-[2-(2,4-dikloorifenyyli)etenyyli]-3,4,5,6-tetrahydro-4-hydroksi-2H-pyranonin trans-diastereomeereil-le. Edelleen HMG-CoA-reduktaasin inhibiitioon tarvitaan ilmeisesti /3-hydroksi-5-laktoni-osan absoluuttista konfiguraatiota, joka osa on yhteinen kaavan (la) 2 Q A τ 7 Q 7 ‘τ o O 7 / HO—ί o · h3c' mukaiselle mevinoliinille ja kaavan (lb) W°
H0-< o H
mukaiselle kompaktiinille. Lynch et ai. ovat esittäneet tämän 4R,6R-konfiguraationa artikkelissa "Synthesis of an HMG-CoA Reductase Inhibitor; A Diastereoselective Aldol Approach" julkaisussa Tetrahedron Letters, Vol. 28, No.
13, s. 1385 - 1388 (1987).
Kuitenkaan alan ammattihenkilö ei voi ennakoida tämän keksinnön odottamatonta ja yllättävää kolesteroli-biosyntee-. sin inhibiitiota näiden julkaisujen perusteella.
Siten tämä keksintö saa aikaan yhdisteitä, jotka koostuvat [R-(R*,R*) ]-2-(4-fluorifenyyli) -/3,5-dihydroksi-5-((1-me-tyylietyyli)-3-fenyyli-4-[(fenyyliamino)karbonyyli]-1H-pyrroli-l-heptaanihaposta (kaavan I mukainen yhdiste) ja sen farmaseuttisesti hyväksyttävistä suoloista. Heptaani- 3 94339 hapon laktonimuoto on (2R-trans)5-(4-fluorifenyyli)-2-(1-metyy1ietyy1i)-N,4-d i fenyy1i-1[2-(tetrahydro-4-hydroks i- 6-okso-2H-pyran-2-yyli)etyyli]lH-pyrroli-3-karboksamidi (kaavan II mukainen yhdiste).
Tämän keksinnön mukaisesti valmistetuista yhdisteistä voidaan valmistaa myös farmaseuttinen koostumus, jota voidaan käyttää hypokolesteroleemisenä aineena ja joka käsittää hypokolesteroleemisesti vaikuttavan määrän [R-(R*,R*)]-2-(4-f luorifenyyli) -/9, δ—dihydroksi-5- (1-metyylietyyli) -3-fenyyli-4-[(fenyyliamino)karbonyyli]-lH-pyrroli-l-heptaa-nihappoa tai sen farmaseuttisesti hyväksyttäviä suoloja ja farmaseuttisesti hyväksyttävää kantoainetta. Edelleen tämän keksinnön mukaisesti valmistettuja yhdisteitä voidaan käyttää menetelmässä hyperkolesterolemiaa sairastavien nisäkkäiden, mukaanlukien ihmisen hoitamiseksi, missä menetelmässä tällaiselle nisäkkäälle annetaan yllä selitetyn farmaseuttisen koostumuksen annostusmuoto.
Tämä keksintö koskee siten menetelmää kaavan I mukaisten yhdisteiden valmistamiseksi, kuten oheisissa vaatimuksissa on esitetty.
Farmaseuttisesti hyväksyttäviä suoloja ovat sellaiset, jotka on tavallisesti muodostettu liuottamalla vapaa happo tai laktoni, etenkin laktoni vesipitoiseen tai vesipitoiseen alkoholiliuottimeen tai muihin sopiviin liuottimiin sopivan emäksen kanssa ja eristämällä suola haihduttamalla liuos tai saattamalla vapaa happo tai laktoni, etenkin laktoni ja emäs reagoimaan orgaanisessa liuottimessa, jos-sa suola erottuu suoraan tai se voidaan saada konsentroimalla liuos.
Käytännössä suolamuodon käyttö merkitsee happo- tai lakto-nimuodon käyttöä. Keksinnön puitteissa sopivia farmaseut- . tisesti hyväksyttäviä suoloja ovat sellaiset, jotka on « ί 4 94339 muodostettu emäksistä, kuten natriumhydroksidista, kalium-hydroksidista, litiumhydroksidista, kalsiumhydroksidista, l-deoksi-2-(metyyliamino)-D-glusitolista, magnesiumhydroksidista, sinkkihydroksidistä, aluminiumhydroksidistä, rauta(II)- tai rauta(III)-hydroksidista, ammoniumhydroksi-dista tai orgaanisista amiineista, kuten N-metyyliglu-kamiinista, koliinista, arginiinista tai vastaavasta. Litium-, kalsium-, magnesium-, aluminium- ja rauta(II)- ja rauta(III)-suolat valmistetaan edullisesti natrium- tai kaliumsuolasta lisäämällä sopivaa reagenssia natrium- tai kaliumsuolan liuokseen, s.o. kalsiumkloridin lisäys kaavan I mukaisen yhdisteen natrium- tai kaliumsuolan liuokseen tuottaa sen kalsiumsuolan.
Vapaa happo voidaan valmistaa hydrolysoimalla kaavan II mukainen laktonimuoto tai ohjaamalla suola kationinvaihto-hartsin (H+-hartsin) läpi ja haihduttamalla vesi.
Tämän keksinnön edullisin suoritusmuoto on [R-(R*,R*)]-2-(4-f luorifenyyli) -0,6-dihydroksi-5- (1-me tyyli etyyli) -3-fenyyli-4-[(fenyyliamino)karbonyyli]-lH-pyrroli-l-heptaa-nihappo-hemikalsiumsuola.
Tavallisesti yhdisteet I ja II voidaan valmistaa (1) erot-: tamalla rasemaatti, joka on valmistettu US-patentissa n:o 4,681,893 esitettyjen menetelmien mukaisesti, joka patentti on tässä viitejulkaisuna, tai (2) syntetisoimalla haluttu kiraalinen muoto lähtöaineista, jotka ovat tunnettuja tai valmistetaan helposti käyttämällä tunnettuja menetelmiä vastaavia menetelmiä.

Kaavion 2 olosuhteet ovat yleisesti, kuten on esitetty esimerkeissä 1-5.
Alan ammattihenkilö tunnistaa kaavioiden 1 ja 2 muunnelmia, jotka ovat sopivia tämän keksinnön mukaisten yhdisteiden valmistamiseksi.
Tämän keksinnön mukaisesti valmistetut yhdisteet ja etenkin kaavan I mukainen yhdiste inhiboivat kolesterolin biosynteesin, kuten on havaittu CSI-seulonta-analyysissä, joka on esitetty US-patentissa n:o 4,681,893, joka on tässä samoin viitteenä. Yhdisteen I, sen enantiomeerin yhdisteen II, ja näiden kahden yhdisteen rasemaatin CSI-arvot ovat seuraavat:

Sekoittamista jatketaan 16 tunnin ajan ja sitten samea liuos konsentroidaan tyhjössä (- 250 sp.). Lisätään to-lueenia (11) ja seos konsentroidaan valkoiseksi kiintoaineeksi (- 100 g). Kiintoaine liuotetaan 1670 ml:aan aseto-nia ja suodatetaan kolmikaulaiseen pulloon, joka on varustettu mekaanisella sekoittimella ja termostaatti-säätöi-sellä lämpömittarilla. Pullo ja suodatin pestään 115 ml:11a veden ja asetonin l:l-seosta ja kirkas liuos jäähdytetään hitaasti. Näin saadaan sakka, joka liuotetaan uu- : delleen kuumentamalla takaisin 65°C:seen. Lisätään edel- « leen 20 ml vettä ja pestään, jolloin saadaan kiteinen tuote, joka eristetään suodattamalla. Kiintoaineet pestään 1200 ml:lla CH3Cl:ää ja tyhjökuivatetaan 255°C:ssa, jolloin saadaan valkoinen kiintoaine. Tämän aineen analyysi osoittaa, että se sisältää 4 % amiinia samoin kuin 0,4 % “ jäämäasetonia ja 0,67 % vettä. Analyyttiset tulokset ovat seuraavat: 22 94339 sulamispiste: 105 - 155°C (hajaantuen) laskettu analyysi: C 63,73, H 6,95, N 5,57, F2 9,53 saatu analyysi: C 62,10, H 6,89, N 5,34, F2 C 61,92, H 7,02, N 5,38, F2 H20 = 0,47 % (KF) HPLC: MeOH, H20, THF (40, 550, 250)
