Description
Mellomprodukt for bruk ved fremstilling av Intermediate product for use in the manufacture of
fenylpyridylaminderivater med antidepressiv virkning. phenylpyridylamine derivatives with antidepressant action.
Foreliggende oppfinnelse angår mellomprodukter for bruk ved fremstilling av nye fenylpyridylaminderivater med antidepressiv virkning, hvilke mellomprodukter har formelen: The present invention relates to intermediates for use in the production of new phenylpyridylamine derivatives with antidepressant action, which intermediates have the formula:
eller et salt derav, hvor Y betegner en avspaltningsgruppe. or a salt thereof, where Y denotes a leaving group.
Sykelige depresjonstilstander har med større eller mindre hell vært behandlet med forskjellige stoffer. De anti-depressive stoffer som har den største kliniske utbredelse er tricykliske tertiære aminer som imipramin med strukturformel: og amitriptylin med formelen:- Morbid depressive states have been treated with more or less success with various substances. The anti-depressants that have the greatest clinical prevalence are tricyclic tertiary amines such as imipramine with the structural formula: and amitriptyline with the formula:-
Sekundære aminer som desipramin med strukturformel: Secondary amines such as desipramine with structural formula:
og 'nortriptylin. med formel: brukes i noe mindre utstrekning. Disse forbindelser har imidlertid sidevirkninger som er uønsket i forbindelse med terapeutisk' bruk, som orto-statisk virkning, anti-cholinergisk virkning .og fremfor alt arrytmogen virkning, d.v.s. hjerte-arrytmi som særlig er sjenerende ved administrasjon av større doser til eldre pasienter. Videre har alle nevnte stoffer den ulempe at den anti-depressive virkning inntrer først etter noen ukers behandlingstid. Videre kjenner man fra litteraturen at visse 1,1-difenyl-3-aminoprop-l-ener, som f.eks. forbindelsen med formel: and 'nortriptyline. with formula: used to a somewhat lesser extent. However, these compounds have side effects which are undesirable in connection with therapeutic use, such as orthostatic action, anti-cholinergic action and above all arrhythmogenic action, i.e. cardiac arrhythmia, which is particularly troublesome when larger doses are administered to elderly patients. Furthermore, all mentioned substances have the disadvantage that the anti-depressant effect only occurs after a few weeks of treatment. Furthermore, it is known from the literature that certain 1,1-diphenyl-3-aminoprop-l-enes, such as e.g. the compound with formula:
har antidepressiv virkning, se J. Med. Chem. 1^, -l6l-*J, (1971). ;Forbindelser med formel:; hvor X betegner klor eller brom og R betegner hydrogen og metyl, beskrives å ha antidepressiv virkning i US-patent nr. 3.,423-510, disse stoffer har imidlertid også en kraftig anti-histamin virkning. Fra litteraturen er det også kjent at en forbindelse med formel: ; har en antidepressiv virkning på dyremodeller, se belgisk patent nr. 781.105. ;I klinisk praksis kjenner man forskjellige typer depresjonstilstander. Nedtrykte pasienter reagerer på forskjellige måter på de forskjellige anti-depressiva som brukes til behandlingen. De fleste av disse forbindelser hemmer nevronal-opptaket av noradrenalin og noen av dem hemmer i tillegg opptak av 5-hydroksytryptamin. Man antar at inhibering av opptaket av 5-hydroksytryptamin er mekanismen bak den humør-forsterkende egenskap som finnes hos noen av disse anti-depressiva. I tillegg til det absolutte hemmingsnivå for opptaket av enten 5-hydroksytryptamin eller noradrenalin er selektiviteten med hensyn til opptak av disse to aminer av stor interesse. ;Hensikten med foreliggende oppfinnelse er å tilveie-bringe mellomprodukter for bruk ved" fremstilling av nye forbindelser med god antidepressiv virkning, som bare gir opphav til mindre bivirkninger, særlig arrytmiske effekter. Likeledes knyttes nerveberoligende virkninger til disse forbindelser. ;Forbindelser som fremstilles ved bruk av foreliggende mellomprodukter har formelen: ; og farmasøytisk anvendelige salter..;På grunn av den manglende frie dreining ved dobbelt-bindingen i ovenstående forbindelse, kan den foreligge i forskjellige stereoisomere former, d.v.s. i cis-transisomere eller i henhold til UIPAC-nomenklaturen (J. Org. Chem. 35, 3849-2867, sept. 1970) i en E-form og en Z-form. Forbindelsen kan brukes terapeutisk som en blanding av geometriske isomere eller-i ren E- eller Z-form. De rene geometriske isomere kan fremstilles fra isomerblanding ut fra isomere utgangsstoffer eller direkte ved stereoselektiv syntese. ;Forbindelsen med formel I kan administreres som en fri base eller et salt av denne med ugiftige syrer. Typiske eksempler på slike salter er hydrobromider, hydroklorider, fosfater, sulfater, sulfamater, laktater, acetater, citrater, tartrater, maleater og malater. ;Ved klinisk praksis vil forbindelsene med formel I vanligvis gis oralt, rektalt eller ved injeksjon, i form av farmasøytiske preparater som inneholder den aktive bestanddel enten som fri base eller som farmasøytisk anvendelig ugiftig syreadhesjonssalt, f.eks. som et sålt av ovenstående type i forbindelse med farmasøytiske bærestoffer. Betegnelser knyttet til nye forbindelser med formel I skal således omfatte både den frie aminbase og de frie basenes syreaddisjonssalter hvor ikke sammen-hengen tilsier noe annet. Bærestoffet kan være et fast, halv-fast eller flytende fortynningsmiddel, eller en kapsel. Vanligvis vil de aktive, stoffer utgjøre fra 0,1 - 95 vekt-% av prepa-ratet, mer spesielt mellom 0,5 og 20 vekt-% for injeksjonsformer og fra 2-50 vekt-% i preparater egnet for oral administrasjon.. ;For fremstilling av farmasøytiske preparater som inneholder forbindelsen med formel I som ;doseringsenheter for oral bruk,- kan den valgte forbindelse blandes med et fast■pulverformet bærestoff som laktose, sakkarose, sorbitol, mannitol, stivelser som potetstivelse, maisstivelse eller amylopektin, cellulosederivater eller gelatin og et smøre-middel som magnesiumstearat, kalsiumstearat eller polyetylen-glykolvokser, og presses til tabletter. Hvis man Ønsker belagte-tabletter kan kjernene som fremstilles som ovenfor, belegges med konsentrerte sukkeroppløsninger som eventuelt kan inneholde gummi arabikum, gelatin, talkum eller titandioksyd. Eventuelt kan tablettene belegges med en lakk oppløst i et lettflyktig organisk oppløsningsmiddei eller en blanding av slike. Fargestoffer kan tilsettes beleggene for lett å kunne skille mellom ;, tabletter inneholdende forskjellige■aktive stoffer eller forskjellige doseringsmengder. ;For fremstilling av myke gelatinkapsler (perleformede lukkede kapsler) inneholdende gelatin og f.eks. glycerol eller lignende lukkede kapsler, kan det aktive stoff blandes med en ;vegetabilsk olje. Hårde gelatinkapsler kan inneholde granulater av aktivt stoff kombinert med faste, pulverformede bærestoffer som laktose, sakkarose, sorbitol, mannitol, stivelser (f.eks. potetstivelse, maisstivelse eller amylopektin), cellulosederivater eller gelatin. ;Doseringsenheter for rektal bruk kan fremstilles i form av.suppositorier som inneholder det aktive stoff i blanding med en nøytral fettsyrebase eller gelatin-rektalkapsler inneholdende det aktive stoff blandet med vegetabilsk olje eller parafinolje. ;Flytende preparater for oral bruk kan ha form av siru-per eller suspensjoner, f.eks. oppløsninger inneholdende fra ca. 0,2 - 20 vekt-/? aktivt stoff, hvor resten utgjør sukker, og en blanding av etanol, vann, glycerol og propylenglykol. Eve.ntuelt kan slike flytende preparater inneholde fargestoffer, smaksmid-ler, sakkarin og karboksymetylcellulose som fortykningsmiddel. ;Oppløsninger.for parenteral bruk ved injeksjon kan lages som vandige oppløsninger av vannoppløselige farmasøytiske salter av den aktive forbindelse, fortrinnsvis i en konsentrasjon på ca. 0,5 10 vekt-$. Disse oppløsninger kan også inneholde stabili- seringsmidler og/eller puffere og kan med fordel formes som doseringsenhets-ampuller. ;Egnede dagsdoser. av forbindelser med formel I ved terapeutisk bruk er- 25 - 250 mg peroralt, fortrinnsvis 50 - 150 mgj og 5 _ 50 mg, fortrinnsvis 10 - 30 mg parenteralt. ;Et preparat i form av doseringsenheter for oral bruk kan inneholde lO - 50 og fortrinnsvis 10 - 2-5 mg aktivt stoff pr. doseringsenbet. ;Den foretrukne forbindelse med formel I som fremstilles ved bruk av foreliggende mellomprodukt er den Z-isomere-med formel: ; Fortrinnsvis fremstilles salter av de aktuelle forbindelser. ;I det følgende beskrives fremstilling av forbindelser med formel I. ;A. Dehydratisering av en forbindelse med formel: ; til en forbindelse med formel I.;Dehydratisering av utgangsstoffet kan f.eks. skje ved behandling med svovelsyre og oppvarming av reaksjonsblandingen.

Chem. 1^, -l6l-*J, (1971). ;Connections with formula:; where X denotes chlorine or bromine and R denotes hydrogen and methyl, is described as having an antidepressant effect in US patent no. 3,423-510, these substances, however, also have a strong anti-histamine effect. It is also known from the literature that a compound with formula: ; has an antidepressant effect in animal models, see Belgian Patent No. 781,105. In clinical practice, different types of depression are known. Depressed patients react in different ways to the different anti-depressants used for treatment. Most of these compounds inhibit the neuronal uptake of noradrenaline and some of them also inhibit the uptake of 5-hydroxytryptamine. It is assumed that inhibition of the uptake of 5-hydroxytryptamine is the mechanism behind the mood-enhancing properties found in some of these anti-depressants. In addition to the absolute inhibition level for the uptake of either 5-hydroxytryptamine or norepinephrine, the selectivity with respect to the uptake of these two amines is of great interest. The purpose of the present invention is to provide intermediates for use in the production of new compounds with good antidepressant action, which only give rise to minor side effects, particularly arrhythmic effects. Similarly, nerve-sedating effects are associated with these compounds.

Org. Chem. 35, 3849-2867, Sept. 1970) in an E form and a Z form. The compound can be used therapeutically as a mixture of geometric isomers or—in pure E or Z form. The pure geometric isomers can be prepared from isomeric mixtures from isomeric starting materials or directly by stereoselective synthesis.;The compound of formula I can be administered as a free base or a salt thereof with non-toxic acids. Typical examples of such salts are hydrobromides, hydrochlorides, phosphates, sulfates, sulfamates, lactates, acetates, citrates, tartrates, maleates and malates. In clinical practice, the compounds of formula I will usually be given orally, rectally or by injection, in the form of pharmaceutical preparations containing the active ingredient either as a free base or as a pharmaceutically usable non-toxic acid adhesion salt, e.g. as a sold of the above type in connection with pharmaceutical carriers. Designations relating to new compounds of formula I shall thus include both the free amine base and the acid addition salts of the free bases where the context does not indicate otherwise. The carrier may be a solid, semi-solid or liquid diluent, or a capsule. Generally, the active substances will make up from 0.1 - 95% by weight of the preparation, more particularly between 0.5 and 20% by weight for injection forms and from 2-50% by weight in preparations suitable for oral administration. For the preparation of pharmaceutical preparations containing the compound of formula I as dosage units for oral use, the selected compound can be mixed with a solid powdered carrier such as lactose, sucrose, sorbitol, mannitol, starches such as potato starch, corn starch or amylopectin, cellulose derivatives or gelatin and a lubricant such as magnesium stearate, calcium stearate or polyethylene glycol wax, and pressed into tablets. If coated tablets are desired, the cores prepared as above can be coated with concentrated sugar solutions which may contain gum arabic, gelatin, talc or titanium dioxide. Optionally, the tablets can be coated with a varnish dissolved in a volatile organic solvent or a mixture of these. Dyes can be added to the coatings to easily distinguish between tablets containing different active substances or different dosage amounts. ;For the production of soft gelatin capsules (bead-shaped closed capsules) containing gelatin and e.g. glycerol or similar closed capsules, the active substance can be mixed with a vegetable oil. Hard gelatin capsules may contain granules of active substance combined with solid, powdered carriers such as lactose, sucrose, sorbitol, mannitol, starches (e.g. potato starch, corn starch or amylopectin), cellulose derivatives or gelatin. Dosage units for rectal use can be produced in the form of suppositories containing the active substance mixed with a neutral fatty acid base or gelatin rectal capsules containing the active substance mixed with vegetable oil or paraffin oil. Liquid preparations for oral use can take the form of syrups or suspensions, e.g. solutions containing from approx. 0.2 - 20 wt-/? active substance, where the rest is sugar, and a mixture of ethanol, water, glycerol and propylene glycol. Eventually, such liquid preparations may contain colourants, flavourings, saccharin and carboxymethyl cellulose as a thickening agent. Solutions for parenteral use by injection can be made as aqueous solutions of water-soluble pharmaceutical salts of the active compound, preferably in a concentration of approx. 0.5 10 weight-$. These solutions can also contain stabilizers and/or buffers and can advantageously be shaped as dosage unit ampoules. ;Suitable daily doses. of compounds of formula I in therapeutic use is 25 - 250 mg perorally, preferably 50 - 150 mgj and 5 - 50 mg, preferably 10 - 30 mg parenterally.

Active uptake is defined as the part of the radioactive uptake that is inhibited by a high concentration of cocaine.
Ved in vitro-metoden ble skiver av must-midthjerne for-inkubert 5 min. med en oppløsning av forsøksforbindelsen og derpå inkubert som ovenfor beskrevet. In the in vitro method, must midbrain slices were pre-incubated for 5 min. with a solution of the test compound and then incubated as described above.
Som -man vil se av tabellen er forbindelsene fremstilt As you will see from the table, the connections are made
i henhold til oppfinnelsen kraftige inhibitorer av nerveopptaket av 5-hydroksytryptamin og noradrenalin. Z-formen av forbindelsen viser kraftigere inhibering av opptak av 5~HT in vivo enn noen av de kjente forbindelser som ble undersøkt. according to the invention powerful inhibitors of the nerve uptake of 5-hydroxytryptamine and norepinephrine. The Z-form of the compound shows stronger inhibition of uptake of 5-HT in vivo than any of the known compounds that were examined.
Z-formen av forbindelsen, undersøkt i form av hydroklorid, er videre en kraftigere inhibitor for opptak av 5~HT in<y>itro enn noen av de tidligere kjente forbindelser. (Forskjel-len som fremkommer mellom virkningen av oksalatet og hydrokloridet antar man skyldes at hydrokloridet er fremstilt ut fra oksalatet slik at man fikk en renere Z-isomer. Forbindelsens E-form vil hovedsakelig inhibere opptak av noradrenalin., Inhibering av nerveopptaket av 5-hydroksytryptamin og noradrenalin som er beskrevet, kan gi forbindelsene verdi som antidepressive The Z-form of the compound, examined in the form of hydrochloride, is furthermore a more potent inhibitor of the uptake of 5-HT in<y>itro than any of the previously known compounds. (The difference that appears between the action of the oxalate and the hydrochloride is assumed to be due to the fact that the hydrochloride has been prepared from the oxalate so that a purer Z-isomer was obtained. The E form of the compound will mainly inhibit the uptake of norepinephrine., Inhibition of the nerve uptake of 5- hydroxytryptamine and norepinephrine which have been described may give the compounds value as antidepressants
midler. Likeledes kan de benyttes som ne.rveberoligende midler. funds. Likewise, they can be used as nerve calming agents.
