Tilsvarende ovennevnte definisjoner kan R eksempelvis bety: metyl, etyl, propyl, iaopropyl, butyl, isobutyl, tert.butyl, allyl. Corresponding to the above definitions, R can mean, for example: methyl, ethyl, propyl, iopropyl, butyl, isobutyl, tert.butyl, allyl.

R<1>kan eksempelvis bety: propyl, isopropyl, butyl, isobutyl, sek.butyl, rettlinjet eller forgrenet amyl (pentyl), heksyl, allyl, videre kommer det som R<1>på tale: benzyl, ot-fenyletyl, 3-fenyletyl. Spesielt foretrukket, er innen oppfinnelsens ramme slike forbindelser som som R<1>inneholder en p^kloalifatisk, eventuelt med alkyl, resp. alkoksy substituert hy&isolea<y>boOTest. Som slike rester skal eksempelvis nevnes: cyklopentyl, cykloheksyl, cykloheptyl, cyklooktyl, metylcykloheksyl, etylcykloheksyl, metoksycykloheksyl, etoksycykloheksyl, idet alkyl- resp. alkoksygruppene kan foreligge i 2-, 3~eller fortrinnsvis i 4-stilling, nemlig såvel i cis- som også i trans-stilling. Cykloheksylmetyl, a- eller g-cykloheksyletyl, endometylencykloheksyl (2,2,1-bicykloheptyl), endoetylencykloheksyl R<1> can mean, for example: propyl, isopropyl, butyl, isobutyl, sec.butyl, straight or branched amyl (pentyl), hexyl, allyl, further R<1> is mentioned: benzyl, o-phenylethyl, 3 -phenylethyl. Particularly preferred, within the scope of the invention, are such compounds which, as R<1>, contain a p^chloroaliphatic, optionally with alkyl, resp. alkoxy substituted hy&isolea<y>boOTest. Examples of such residues should be mentioned: cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, methylcyclohexyl, ethylcyclohexyl, methoxycyclohexyl, ethoxycyclohexyl, as alkyl- or the alkoxy groups can be present in the 2-, 3- or preferably in the 4-position, namely both in the cis- and also in the trans-position. Cyclohexylmethyl, a- or g-cyclohexylethyl, endomethylenecyclohexyl (2,2,1-bicycloheptyl), endoethylenecyclohexyl

(2,2,2-bicyklooktyl), endometylencykloheksenyl, endoetylencyklo-heksenyl, endometylencykloheksylmetyl, endoetylencykloheksylmetyl, endometyléncykloheksenylmetyl eller endoetylencykloheksenylmetyl.

De nevnte benzolsulfonyl-karbaminsyreestere, resp. -tiolkarbaminsyreestere kan i alkoholkomponenten ha en alkylrest eller en arylrest eller også en heterocyklisk rest. Da denne rest avspaltes ved reaksjonen har dens kjemiske konstitusjon ingen inn-virkning på sluttproduktets karakter, og kan derfor varieres innen vide grenser. Det samme gjelder for de F^-substituerte karbaminsyreestere, resp. de tilsvarende tiolkarbaminsyreestere. The mentioned benzenesulfonyl-carbamic acid esters, resp. -thiocarbamic acid esters can have an alkyl residue or an aryl residue or also a heterocyclic residue in the alcohol component. As this residue is split off during the reaction, its chemical constitution has no effect on the character of the final product, and can therefore be varied within wide limits. The same applies to the F^-substituted carbamic acid esters, resp. the corresponding thiolcarbamic acid esters.

Som karbaminsyrehalogenider egner det seg i første rekke As carbamic acid halides, it is primarily suitable

kloridene.the chlorides.

De som utgangsstoffer for fremgangsmåten aktuelle Those as starting materials for the procedure in question

benzolsulfonylurinstoffer kan på den side av urinstoffmolekylet som vender bort fra sulfonylgruppen være usubstituert eller være substituert en eller spesielt to ganger. Da disse substituenter avspaltes ved reaksjonen med aminene, kan deres karakter varieres innen vide grenser. Ved siden av alkyl-, aryl-, acyl- eller heterocyklisk benzenesulfonylureas can, on the side of the urea molecule facing away from the sulfonyl group, be unsubstituted or substituted once or especially twice. As these substituents are split off during the reaction with the amines, their character can be varied within wide limits. Next to alkyl, aryl, acyl or heterocyclic

substituerte benzolsulfonylurinstoffer kan man også anvende bis-(benzolsulfonyl)-urinstoffer som ved et av nitrogenatomene dessuten substituted benzenesulfonylureas, you can also use bis-(benzenesulfonyl)ureas which, at one of the nitrogen atoms, also

kan ha en ytterligere substituent, f.eks. metyl. Man kan eksempelvis behandle slike bis-(benzolsulfonyl)-urinstoffer eller også N-benzolsulfonyl-N<1->acylurinstoffer med R<1->substituerte aminer og oppvarme may have a further substituent, e.g. methyl. One can, for example, treat such bis-(benzenesulfonyl)ureas or also N-benzenesulfonyl-N<1->acylureas with R<1->substituted amines and heating

de dannede salter til forhøyede temperaturer, spesielt slike over they formed salts at elevated temperatures, especially those above

100°C. 100°C.

Videre er det mulig å gå ut fra urinstoffer med formel Furthermore, it is possible to proceed from urine substances with a formula

eller fra slike urinstoffer som ved det frie nitrogenatom dessuten er en- eller spesielt to-ganger substituert, og å omsette disse med gruppen or from such urea substances which are additionally substituted once or especially twice at the free nitrogen atom, and reacting these with the group

-substituerte benzolsulfonamider. Som slike utgangsstoffer, kommer det eksempelvis på tale N-cykloheksyl- eller N-(4-metyl-cykloheksyl)-urinstoffer, de tilsvarende N<1->acetyl-, N<*->nitro-, N'-cykloheksyl-, Nf<->(4-metyl-cykloheksyl)-, NJN<*->difenyl- (idet de to fenylrester også kan være substituert såvel som forbundet med hverandre direkte eller -substituted benzenesulfonamides. Such starting substances include, for example, N-cyclohexyl or N-(4-methyl-cyclohexyl)-ureas, the corresponding N<1->acetyl-, N<*->nitro-, N'-cyclohexyl-, Nf<->(4-methyl-cyclohexyl)-, NJN<*->diphenyl- (since the two phenyl residues can also be substituted as well as connected to each other directly or

også over et broledd som -CH2~, -NH-, -0- eller -S-), N'-metyl-N'-fenyl-, NJN<*->dicykloheksylurinstoffer såvel som Y-substituerte cyklo-heksylkarbamoylimidazoler eller -triazoler. also over a bridge link such as -CH2~, -NH-, -0- or -S-), N'-methyl-N'-phenyl-, NJN<*->dicyclohexylureas as well as Y-substituted cyclohexylcarbamoylimidazoles or -triazoles .

Hydrolysen av de som utgangsstoffer nevnte benzolsulfonyl-parabansyrer, -isourinstoffetere, -isotiourinstoffetere, isourinstoffestere eller -halogenmaursyreamidiner foregår hensiktsmessigst i alkalisk miljø. Isourinstoffetere og isourinstoffestere kan også hydrolyseres i et surt medium med godt resultat. The hydrolysis of the benzolsulfonyl-parabanic acids, -isourea ethers, -isothiourea ethers, isourea esters or -haloformic acid amidines mentioned as starting materials most conveniently takes place in an alkaline environment. Isourea ethers and isourea esters can also be hydrolysed in an acidic medium with good results.

Omsetningen av benzolsulfohalogenider med R^-substituerte urinstoffer foregårhensiktsmessig under anvendelse av sterkt basiske kondensasjonsmidler som alkalimetaller, alkaliamider eller fortrinnsvis -hydrider i indifferente oppløsniirgsmidler. The reaction of benzenesulfohalides with R 1 -substituted ureas conveniently takes place using strongly basic condensing agents such as alkali metals, alkali amides or preferably -hydrides in indifferent solvents.

Omsetningen av sulfinsyrer eller sulfinsyreklorider med hydroksyurinstoffer kan hensiktsmessig foregå i indifferende oppløs-ningsmidler. Velger man sulfinsyrene eller deres alkalisalter som utgangsstoffer, så er det nødvendig sure kondensasjonsmidler som eksempelvis tionylklorid, polyfosforsyrer, vannfri fosforsyre eller svovelsyre. The reaction of sulfinic acids or sulfinic acid chlorides with hydroxyureas can suitably take place in indifferent solvents. If you choose the sulfinic acids or their alkali salts as starting materials, acidic condensation agents such as thionyl chloride, polyphosphoric acids, anhydrous phosphoric acid or sulfuric acid are necessary.

Erstatningen av tiourinstoff med svovelatom med et oksygenatom i de tilsvarende substituerte benzolsulfonyl-tiourinstoffer kan foregå på kjent måte, f.eks., ved hjelp av oksyder eller salter av tungmetaller eller også ved anvendelse av oksydasjonsmidler som hydrogenperoksyd, natriumperoksyd eller salpetersyrling. The replacement of thiourea with a sulfur atom by an oxygen atom in the correspondingly substituted benzenesulfonyl-thioureas can take place in a known manner, for example, by means of oxides or salts of heavy metals or also by the use of oxidizing agents such as hydrogen peroxide, sodium peroxide or nitric acid.

Tiourinstoffene kan også avsvovles ved behandling med fosgen eller fosforpentaklorid. Som mellomtrinn dannede klormaursyre-amidiner, resp. -karbodiimider kan ved egnede forholdsregler som forsåpning eller tilleiring av vann overføres i benzolsulfonylurinstoffene. The thioureas can also be desulphurised by treatment with phosgene or phosphorus pentachloride. As an intermediate step, chloroformate amidines formed, resp. -carbodiimides can be transferred into the benzenesulfonylureas by suitable precautions such as saponification or addition of water.

Oksydasjonen av benzolsulfinyl-resp. sulfenylurinstoffer kan gjennomføres med de kjente oksydasjonsmidler som f.eks. kalium- permanganat i indifferente oppløsningsmidler. The oxidation of benzenesulfinyl-resp. Sulphenylureas can be carried out with the known oxidizing agents such as e.g. potassium permanganate in indifferent solvents.

Tilsvarende substituerte benzolsulfonylurinstoffer som i molekylet inneholder en umettet binding, f.eks. Correspondingly substituted benzenesulfonylureas which contain an unsaturated bond in the molecule, e.g.

kan ved hydrering, f.eks. med molekylært hydrogen i nærvær av en kjent hydreringskatalysator overføres i benzolsulfonylurinstoffene ifølge oppfinnelsen. can by hydration, e.g. with molecular hydrogen in the presence of a known hydrogenation catalyst is transferred in the benzenesulfonylureas according to the invention.

Acyleringen av aminoalkylbenzolsulfonylurinstoffer kan enten utføres i et trinn, f.eks. ved omsetning av tilsvarende substituerte benzosyrehalogenider, den kan også utføres i flere trinn. The acylation of aminoalkylbenzenesulfonylureas can either be carried out in one step, e.g. by reacting correspondingly substituted benzoic acid halides, it can also be carried out in several steps.

Svovelatomets erstatning i tilsvarende substituerte tio-benzamidoalkylbenzolsulf onylurinstoffer eller -tiourinstoffer med oksygenatomer kan eksempelvis utføres ved hjelp av oksydasjonsmidler som hydrogenperoksyd, natriumperoksyd eller andre peroksydforbindelser. The replacement of the sulfur atom in correspondingly substituted thio-benzamidoalkylbenzenesulfonylureas or -thioureas with oxygen atoms can be carried out, for example, by means of oxidizing agents such as hydrogen peroxide, sodium peroxide or other peroxide compounds.

Istedenfor tiobenzamidoalkylbenzolsulfonylurinstoffer,Instead of thiobenzamidoalkylbenzenesulfonylureas,

kan også tilsvarende tiobenzamidoalkylbenzolsulfonylisotiourinstoff-etere, -isourinstoffetere, resp. -estere, -parabansyrer eller -halogenmaursyreamidiner avsvovles ved behandling med oksydasjonsmidler i surt eller alkalisk miljø under samtidig hydrolytisk fri-gjøring av sulfonylurinstoffgrupperingen til benzamidoalkylbenzol-sulfonylurinstoffer. can also correspond to thiobenzamidoalkylbenzenesulfonyl isothiourea ethers, isourea ethers, resp. -esters, -parabanic acids or -haloformic amidines are desulphurized by treatment with oxidizing agents in an acidic or alkaline environment with simultaneous hydrolytic release of the sulfonylurea grouping to benzamidoalkylbenzene-sulfonylureas.

kan generelt variere sterkt med hensyn til reaksjonsbetingelsene og tilpasses de eventuelle forhold. Eksempelvis kan omsetningen gjennom-føres i fravær eller nærvær av oppløsningsmidler ved værelsetemperatur eller forhøyet temperatur. can generally vary greatly with regard to the reaction conditions and can be adapted to any conditions. For example, the reaction can be carried out in the absence or presence of solvents at room temperature or elevated temperature.

Alt etter utgangsstoffen.es karakter kan en eller annen av de omtalte fremgangsmåter i enkelte tilfeller gi et ønsket individuelt benzolsulfonylurinstoff bare i små utbytter, og ikke være egnet til dets syntese. I slike forholdsvis sjelden opptredende tilfeller byr det for fagfolk ingen vanskeligheter å syntetisere det ønskede pro-dukt på en annen av de omtalte fremgangsmåter. Depending on the nature of the starting material, one or another of the described methods may in some cases give a desired individual benzenesulfonylurea only in small yields, and not be suitable for its synthesis. In such relatively rarely occurring cases, there are no difficulties for experts in synthesizing the desired product using another of the mentioned methods.

Utgangsstoffenes fremstilling foregår etter generelt kjente metoder. Således kan eksempelvis som utgangsmateriale anvendte benzolsulfonamider som ved benzolkjernen er substituert med resten The production of the starting materials takes place according to generally known methods. Thus, for example, benzenesulfonamides can be used as starting material which have been substituted by the residue at the benzene nucleus

fåes ved omsetning av de tilsvarende benzolforbindelser med klor-sulfonsyre og deretter med ammoniakk, eller ved acylering av amino-forbindelser med formel are obtained by reacting the corresponding benzene compounds with chlorosulfonic acid and then with ammonia, or by acylating amino compounds with the formula

med tilsvarende syreklorider. with corresponding acid chlorides.

Som utgangsmateriale anvendte benzolsulfonyluretaner og -urinstoffer kan eksempelvis fåes av benzolsulfonamider og halogen-maursyrealkylestere, resp. kaliumcyanat (KOCN). Benzenesulfonyl urethanes and ureas used as starting materials can, for example, be obtained from benzenesulfonamides and halogen-formic acid alkyl esters, resp. potassium cyanate (KOCN).

De omtalte benzolsulfonylurinstoffderivaters blodsukkersenkende virkning kunne fastslås ved at man foret dem i doser på 10 mg/kg til kaniner, og bestemte blodsukkerverdien etter den kjente metode av Hagedorn-Jensen eller med en autoanalysør over et lengre tidsrom. The blood sugar-lowering effect of the mentioned benzenesulfonylurea derivatives could be determined by feeding them in doses of 10 mg/kg to rabbits, and determining the blood sugar value according to the known method of Hagedorn-Jensen or with an autoanalyzer over a longer period of time.

Således ble det eksempelvis fastslått at 10 mg/kg N-/—4-(3-<2-metoksy-4-trifluormetylbenzamiclo>-etyl)-benzolsulfonyl7-N' - (4-metyl-cykloheksyl)-urinstoff etter 3 !fcimer bevirker en blodsukkersenkning på l6#, som etter 24 timerfisågar utgjør 2535, og først etter 48 timer igjen er sunket til nullveMien. Thus, for example, it was determined that 10 mg/kg N-(4-(3-<2-methoxy-4-trifluoromethylbenzamiclo>-ethyl)-benzenesulfonyl7-N'-(4-methyl-cyclohexyl)-urea after 3 causes a drop in blood sugar of l6#, which after 24 hours amounts to 2535, and only after 48 hours again has it dropped to the zero level.

På samme måte bevirker IQ ag M-/¥-(B-<2-etoksy-5-acetyl-benzamido>-etyl)-benzolsulf onyl7-N'-(|^9jcfj4oyJKl0heksyl)--urin8tof f etter 3 timer en blodsukkersenkning crøsfcpsnt 32g som etter 24 timer ennå utgjør 2135, mens det kjente N-/¥-mefcj?ll)Qnzol8uifonyl7-N'-butylurin- stoff med en dosering på mindre enn 25 mg/kg til kaniner ikke frem-bringer noen senkning av blodsukkerspeilet mer. In the same way, IQ ag M-/¥-(B-<2-ethoxy-5-acetyl-benzamido>-ethyl)-benzenesulfonyl7-N'-(|^9jcfj4oyJKl0hexyl)--urin8tof f after 3 hours causes a blood sugar lowering crøsfcpsnt 32g which after 24 hours still amounts to 2135, while the known N-/¥-mefcj?ll)Qnzol8ufonyl7-N'-butylurea with a dosage of less than 25 mg/kg to rabbits does not produce any further lowering of the blood sugar level .

De omtalte benzolsulfonylurinstoffers sterke virkning blir spesielt tydelig når man ytterligere nedsetter dosen. Administrerer man N-/~~4-({3- ( 2-metoksy-5-acetylbenzamido^-etyl)-benzolsulfonyl7-N»-(4-metyl-cykloheksyl)-urinstoff i en dosering på 0,2 mg/kg, N-/~4-(p-2-metoksy-4-trifluormetylbenzamido-etyl)-benzolsulfonyl7-N,-cykloheksyl-urinstoff i en dosering på 0,1 mg/kg og N-/~4-(P-< 2-metoksy-4-trifluor-metylbenzamido)-etyl)-benzolsulfonyl7-N»-(4-metylcykloheksyl)-urinstoff i en dosering på 0,08 mg/kg på kaniner, så kan det stadig fastslås en tydelig blodsukkersenkning. The strong effect of the mentioned benzenesulfonylureas becomes particularly evident when the dose is further reduced. N-[~4-({3-(2-Methoxy-5-acetylbenzamido^-ethyl)-benzenesulfonyl7-N''-(4-methyl-cyclohexyl)-urea is administered in a dosage of 0.2 mg/kg , N-/~4-(p-2-methoxy-4-trifluoromethylbenzamido-ethyl)-benzenesulfonyl7-N,-cyclohexyl-urea in a dosage of 0.1 mg/kg and N-/~4-(P-< 2-Methoxy-4-trifluoro-methylbenzamido)-ethyl)-benzenesulfonyl7-N»-(4-methylcyclohexyl)-urea in a dosage of 0.08 mg/kg in rabbits, a clear lowering of blood sugar can still be determined.

De omtalte benzolsulfonylurinstoffer skal fortrinnsvis tjene til fremstilling av oralt administrerbare preparater med blodsukkersenkende virkning til behandling av diabetes mellitus og kan applisere som sådan eller i form av deres salter, resp. i nærvær av stoffer som fdrer til en saltdannelse. Til saltdannelse kan det eksempelvis anvendes alkaliske midler som alkali- eller jordalkalihydroksyder, The mentioned benzenesulfonylureas should preferably be used for the production of orally administrable preparations with a blood sugar-lowering effect for the treatment of diabetes mellitus and can be applied as such or in the form of their salts, resp. in the presence of substances that lead to salt formation. For salt formation, for example, alkaline agents such as alkali or alkaline earth hydroxides can be used,

-karbonater eller -bikarbonater.-carbonates or -bicarbonates.

Som medisinske preparater kommer det fortrinnsvis på tale As medical preparations, it is preferably mentioned

tabletter som ved siden av fremgangsmåteproduktene inneholder de van-lige hjelpe- og bærestoffer som talkum, stivelse, melkesukker, tragant eller magnesiumstearat. tablets which, in addition to the process products, contain the usual auxiliary and carrier substances such as talc, starch, milk sugar, tragacanth or magnesium stearate.

Et preparat som inneholder de omtalte benzolsulfonylurinstoffer som virksomt stoff, f.eks. en tablett eller et pulver med eller uten de nevnte tilsetninger er hensiktsmessig bragt i en egnet dosert form. Som dosis er det da å velge en slik som er tilpasset virkningen av det anvendte benzolsulfonylurinstoff og den Ønskede effekt. Hensiktsmessig utgjor doseringen pr. enhet ca. 0,5 til 100 mg, fortrinnsvis 2 til 10 mg, imidlertid kan det også anvendes betraktelig hOyere eller lavere-liggende doseringsenheter som eventuelt fSr applikasjon må oppdeles, resp. deles flere ganger. A preparation containing the mentioned benzenesulfonylureas as active substance, e.g. a tablet or a powder with or without the aforementioned additives is suitably brought into a suitable dosage form. The dose is then to choose one that is adapted to the effect of the benzenesulfonylurea used and the desired effect. Appropriately, the dosage per unit approx. 0.5 to 100 mg. shared several times.
