Abstract
Nye kalsilytiske forbindelser og fremgangsmåter for anvendelse av dem er tilveiebrakt.
Description
Foreliggende oppfinnelse angår nye forbindelser i stand til å inhibere kalsiumreseptoraktivitet og anvendelse av slike forbindelser samt en farmasøytisk sammensetning inneholdende en slik forbindelse. Forbindelsene som her er beskrevet kan administreres til pasienter for å oppnå en terapeutisk effekt.
Foreliggende oppfinnelse angår nye kalsilytiske forbindelser, farmasøytiske sammensetninger som inneholder disse forbindelsene og deres anvendelse som kalsiumreseptorantagonister.
Hos pattedyr er ekstracellulær Ca<2+>under streng homeostatisk kontroll og regulerer forskjellige prosesser slik som blodlevring, nerve- og muskeleksiterbarhet og riktig bendannelse. Ekstracellulær Ca<2+>inhiberer sekresjon av paratyroidhormon ("PTH") fra paratyroidceller, inhiberer benresorpsjon ved osteoklaster, og stimulerer sekresjon av kalsitonin fra C-celler. Kalsiumreseptorproteiner gjør det mulig for visse spesialiserte celler å respondere på forandringer i ekstracellulær Ca<2+>konsentrasjon.
PTH er hovedendokrinfaktoren som regulerer Ca<2+>homeostase i blod og ekstracellulære fluider. PTH øker nivået av Ca<2+>i blodet, ved å virke på ben- og nyreceller. Denne økningen i ekstracellulært Ca<2+>virket deretter som et negativt feedback signal, som undertrykker PTH-sekresjon. Det resiproke forholdet mellom ekstracellulært Ca<2+>og PTH-sekresjon utgjør en viktig mekanisme som opprettholder kroppens Ca<2+>homeostase.
Ekstracellulært Ca<2+>virker direkte på paratyroidceller for å regulere PTH sekresjon. Eksistensen av et paratyroidcelleoverflateprotein som detekterer forandringer i ekstracellulært Ca<2+>har blitt bekreftet. Se Brown et al, Nature 366:574, 1993.1 paratyroidceller virker dette proteinet, kalsiumreseptoren, som en reseptor for ekstracellulær Ca 94- , detekterer forandringer i ionekonsentrasjon av ekstracellulært Ca<94->og initierer en funksjonell cellulær respons, PTH sekresjon.
Ekstracellulært Ca<2+>påvirker forskjellige cellefunksjoner, gjennomgått i Nemeth et al., Cell Calcium 11:319, 1990. For eksempel spiller ekstracellulært Ca en rolle i parafollikulære (C-celler) og paratyroidceller. Se Nemeth, Cell Calcium 11:323,1990. Rollen til ekstracellulært Ca<2+>på benosteoklaster har også blitt studert. Se Zaidi, Bioscience Reports 10:493, 1990.
Forskjellige forbindelser er kjente for å etterligne effektene til ekstracellulært Ca^<+>på et kalsiumreseptormolekyl. Kalsilytiske midler er forbindelser som er i stand til å inhibere kalsiumreseptoraktivitet, som derved forårsaker en reduksjon i en eller flere kalsiumreseptoraktiviteter fremkalt av ekstracellulært Ca^<+>. Kalsilytiske midler er anvendelige som ledemolekyler i oppdagelsen, utviklingen, utformingen, modifikasjonen og/eller konstruksjonen av anvendelige kalsiummodulatorer, som er aktive ved Ca^<+>reseptorer. Slike kalsilytiske midler er anvendelige ved behandling av forskjellige sykdomstilstander kjennetegnet ved anormale nivåer av en eller flere komponenter, f.eks. polypeptider slike som hormoner, enzymer eller vekstfaktorer, hvis ekspresjon og/eller sekresjon er regulert eller påvirket av aktiviteten ved en eller flere Ca^<+>reseptorer. Målsykdommer eller forstyrrelser for kalsilytiske forbindelser inkluderer sykdommer som involverer anormal ben- eller mineralhomeostase.
Anormal kalsiumhomestase er kjennetegnet ved en eller flere av følgende aktiviteter: en anormal økning eller reduksjon i serumkalsium; en anormal økning eller reduksjon av urinutskillelse av kalsium; en anormal økning eller reduksjon i benkalsiumnivåer (for eksempel som bedømt ved benmineraltetthetsmålinger); en anormal absorpsjon av diettkalsium; en anormal økning eller reduksjon i produksjon og/eller frigivelse av messengerer som påvirker serumkalsiumnivåer slik som PTH og kalsitonin; og en anormal forandring i responsen fremkalt ved messengerer som påvirker serumkalsiumnivåer.
Således gir kalsiumreseptorantagonister en unik tilnærming overfor farmakoterapien i forbindelse med sykdommer assosiert med anormal ben- eller mineralhomeostase, slik som hypoparatyroidisme, osteosarkoma, periodontal sykdom, frakturhelning, osteoartritt, reumatoid artritt, Pagefs sykdom, humoral hyperkalsemi assosisert med malignans og fraturhelning, og osteoporose.
Foreliggende oppfinnelse angår generelt kalsilytiske forbindelser. "Kalsilytiske forbindelser" refererer til forbindelser som er i stand til å inhibere kalsiumreseptoraktivitet. Evnen til en forbindelse til å "inhibere kalsiumreseptoraktivitet" betyr at forbindelsen forårsaker en reduksjon i en eller flere kalsiumreseptoraktiviteter fremkalt ved ekstracellulært Ca<2+>.
Anvendelsen av kalsilytiske forbindelser for å inhibere kalsiumreseptoraktivitet og/eller oppnå en fordelaktig effekt hos pasienter er beskrevet nedenfor. Også beskrevet nedenfor er teknikker som kan anvendes for å oppnå ytterligere kalsilytiske forbindelser.
Foreliggende oppfinnelse vedrører nærmere bestemt forbindelsen 3-{3,4-difluor-5-[(R)-2-hydroksy-3-(2-indan-2-yl-1,1 -dimetyletylamino)-propoksy]-fenyl} -propionsyre eller farmasøytisk akseptabelt salt derav.
I en foretrukket utførelsesform er forbindelsen ifølge oppfinnelsen 3-{3,4-difluor-5-[(R)-2-hydroksy-3-(2-indan-2-yl-1,1 -dimetyletylamino)-propoksy]-fenyl} -propionsyre.
I en ytterligere foretrukket utførelsesform er forbindelsen 3-{3,4-difluor-5-[(R)-2-hydroksy-3-(2-indan-2-yl-1,1 -dimetyletylamino)-propoksy]-fenyl} -propionsyre hydroklorid.
Foreliggende søknad demonstrerer evnen til kalsilytiske forbindelser til å fremvise en fysiologisk relevant effekt på en celle ved å illustrere evnen av slike forbindelser til å øke PTH sekresjon og også identifisere et målsete for kalsilytiske forbindelser.

Til en acetonløsning (0,1 M, 240 mL) av kommersielt tilgjengelig 5-brom-2,3-difluorfenol (5,0 g, 23,93 mmol) ble det tilsatt K2CO3(9,92 g, 71,77 mmol), og blandingen ble varmet til tilbakeløp i 30 min. Etter avkjøling av denne blandingen til romtemperatur, ble (2R)-(-)-glycidyl 3-nitrobenzensulfonat (6,20 g, 23,93 mmol) tilsatt, og den resulterende blandingen ble varmet til tilbakeløp over natten. Etter avkjøling til romtemperatur, ble de faste stoffene fjernet ved filtrering og blandingen ble vasket godt med etylacetat. Filtratet ble konsentrert og fordelt mellom etylacetat og IN HC1. Den organiske delen ble vasket suksessivt med 5% NaHCC«3 og saltvann, tørket (MgSC>4), filtrert og konsentrert til et faststoff. Rensing med FCC (15% etylacetat/heksaner) ga produktet som et hvitt faststoff i 97% utbytte (6,19 g).

(c) (E)-3-{3,4-difluor-5-[(R)-2-hydroksy-3-(2-indan-2-yl-l,l-dimetyl-etylamino)-propoksy]-fenyl}-akrylsyre hydroklorid
Til en løsning av bromidet i eksempel lb (21,0 g, 46,26 mmol) i avgasset propionitril (0,2 M, 230 mL) ble det tilsatt Pd(OAc)2(0,52 g, 2,31 mmol), P(o-tol)3(2,11 g, 6,94 mmol), DIPEA (17,7 mL, 101,76 mmol), og etylakrylat (6,51 mL, 60,13 mmol). Reaksjonskolben ble utstyrt med en kjøler, holdt under Ar dekke, og plassert på et forhåndsoppvarmet bad (115 °C) i 3,5 timer. Etter avkjøling til romtemperatur ble reaksjonsblandingen filtrert gjennom Celitt, og filtratet ble konsentrert, fordelt mellom etylacetat og IN HC1. Sjiktene ble separert og den organiske delen ble vasket suksessivt med 5% NaHCC«3 og saltvann, tørket (MgSC^), filtrert og konsentrert til en brun olje.
En porsjon av det urene residuet (6,2 g) ble brakt opp i etanol og vann (0,2 M, 50 mL, 13 mL) og behandlet med 2N NaOH (13 mL). Reaksjonsblandingen ble omrørt ved romtemperatur i 12 timer. Etanolen ble fjernet og den vandige porsjonen (pH 14) ble fortynnet opptil 200 mL og ekstrahert 3x med 30 mL porsjoner av dietyleter. Vandig HC1 ble tilsatt under omrøring for å justere pH til 5, hvilket forårsaket at produktet kom ut av løsningen som en gummi. CH2CI2ble tilsatt, og tofaseblandingen ble omrørt godt i 5-30 min. Ved denne fremgangsmåten ble produktet omdannet til et hvitt faststoff som ble isolert som rent zwitterion ved filtrering (3,3 g, 70 % over 2 trinn).
Til en acetonitrilsuspensjon av zwitterionproduktet ble det tilsatt 2M HC1 i dietyleter. Materialet gikk sakte over i løsning og presipiterte deretter som et hvitt krystallinsk faststoff for å gi (E)-3-{3,4-difluor-5-[(R)-2-hydroksy-3-(2-indan-2-yl-l,l-dimetyl-etylamino)-propoksy]-fenyl}-akrylsyre som det rene HC1 saltet.<J>H NMR (dmso-d6): 5 12.53 (s, 1H); 8.91 (m, 1H); 8.58 (m, 1H); 7.54 (d, J = 16.0 Hz, 1H); 7.49 (m, 2H); 7.18 (m, 2H); 7.11 (m, 2H); 6.67 (d,7 = 16.0 Hz, 1H); 6.0 (d, J = 4.4 Hz, 1H); 4.27 (m, 1H); 4.23 (m, 2H); 3.17 (m, 1H); 3.09 (dd, J = 13.4, 7.05 Hz, 2H); 2.96 (m, 1H); 2.56 (m, 3H); 1.96 ( d, J = 5.4 Hz, 2H); 1.39 (s, 6H).

Til en løsning av akrylsyren i eksempel 1 (2,5 g, 5,62 mmol) i eddiksyre (30 mL) og etylacetat (20 mL) ble det tilsatt 5% Pd/CaC03(0,50 g). Reaksjonskolben ble spylt med H2og forseglet under en H2ballong i 15 timer. Blandingen ble filtrert gjennom celitt, og filtratet ble konsentrert til ca. 5 mL volum. Toluen (100 mL) og 2M HC1 i dietyleter (10 mL) ble tilsatt og løsningen ble konsentrert til et hvitt faststoff.
Det faste stoff ble suspendert i acetonitril og behandlet med 2M HC1 i dietyleter. Denne løsningen ble konsentrert til tørrhet hvilket ga tittelforbindelsen som HC1 saltet som et
