For fremstillingen av de nevnte benzolsulfonylurinstoffer kan man i tilsvarende substituerte benzolsulfonyltiourinstoffer på kjent måte erstatte svovelatom med et oksygenatom og eventuelt be-handle fremgangsmåteproduktene med alkaliske midler for saltdannelse.

Alt etter naturen av leddene Z, Z' og Z", X og R' vil i enkelte tilfelle den nevnte fremgangsmåte for fremstilling av.de individuelle forbindelser som faller under den generelle formel være uegnet eller i det minste nødvendiggjøre forholdsregler for be-skyttelse av aktive grupper. Slike forholdsvis sjelden opptredende tilfelle kan lett fastslås av fagfolk, og det byr ikke på noen vanskeligheter i slike tilfelle med resultat å anvende en annen syn-tesemåte, slik den er beskrevet i ovenfor omtalte uti. skrifter. Således er det under tiden nødvendig ved foretring eller forestring å beskytte hydroksygrup-per plasert i stedet for Z, ved forestring å beskytte ved tilsvarende steder plaserte karboksygrupper eller også å beskytte ved ringslutning til ftalimid-derivat en til karbonamidgruppen i o-stilling stå-ende karboksygruppe, som beskrevet i uti. skrift nr. 118 555. Lignende gjelder i de tilfelle hvor R' er en merkaptogruppe. Depending on the nature of the links Z, Z' and Z", X and R', in some cases the aforementioned method for producing the individual compounds that fall under the general formula will be unsuitable or at least necessitate precautions for the protection of active groups. Such relatively rarely occurring cases can be easily established by professionals, and it does not pose any difficulties in such cases to use another method of synthesis with results, as described in the above-mentioned publications. Thus, it is currently necessary by etherification or esterification to protect hydroxy groups placed in place of Z, by esterification to protect carboxy groups placed in corresponding places or also to protect by cyclization to a phthalimide derivative a carboxy group standing to the carbonamide group in the o-position, as described in publication no. 118 555. The same applies in cases where R' is a mercapto group.
Svovelatomets erstatning med et oksygenatom i de tilsvarende substituerte benzolsulfonyltiourinstoffer kan eksempelvis utføres ved hjelp av oksy-der eller salter av tungmetaller eller også ved anvendelse av oksydasjonsmidler, som hydrogenperoksyd, natriumperoksyd eller salpetersyrling. Tiourin-stoffene kan også avsvovles ved behandling med fosgen eller fosforpentaklorid. Som mellomprodukt dannede klormaursyreamidiner resp. -karbodiimider kan ved egnede forholdsregler, som forsåpning eller tilleiring av vann, overføres i benzolsulfonylurin-stoffene. The replacement of the sulfur atom with an oxygen atom in the correspondingly substituted benzenesulfonylthioureas can be carried out, for example, by means of oxides or salts of heavy metals or also by using oxidizing agents, such as hydrogen peroxide, sodium peroxide or nitric acid. The thiourine substances can also be desulphurised by treatment with phosgene or phosphorus pentachloride. As an intermediate product, chloroformate amidines resp. -carbodiimides can be transferred into the benzenesulfonylureas by suitable precautions, such as saponification or addition of water.
Anvendelsen av ftalimidforbindelser ved Z = karboksyl i ortostilling til karbonamidgrupperingen er prinsipielt mulig ved alle reaksjonstyper. Ftali-midrestens oppspaltning kan foregå ved hjelp av alkali, den inntrer imidlertid generelt allerede ved reaksjonen eller ved reaksjonsproduktets oppar-beidelse. Ved anvendelse av estere eller benzyletere kan det etterpå foregå en spaltning til de frie forbindelser. The use of phthalimide compounds with Z = carboxyl in the ortho position to the carbonamide grouping is in principle possible for all reaction types. The splitting of the phthalic intermediate residue can take place with the aid of alkali, but it generally already occurs during the reaction or during the preparation of the reaction product. When esters or benzyl ethers are used, cleavage to the free compounds can subsequently take place.
Utførelsesformen av fremgangsmåten ifølge oppfinnelsen kan generelt varieres sterkt med hen-syn, til reaksjonsbetingelser og tilpasses de even-tuelle forhold. Eksempelvis kan omsetningene gjenomføres under anvendelse av oppløsningsmid-ler ved værelsetemperatur eller ved forhøyet temperatur. The embodiment of the method according to the invention can generally be varied greatly with regard to reaction conditions and adapted to any conditions. For example, the reactions can be repeated using solvents at room temperature or at an elevated temperature.
De ved hjelp av fremgangsmåten ifølge oppfinnelsen oppnåelige benzolsulfonylurinstoff-deri-vater er verdifulle legemidler, som utmerker seg ved en sterk og fremfor alt langvarig blodsukkersenkende virkning. Deres blodsukkersenkende virkning kunne f. eks. fastslås på kaniner ved at man foret fremgangsmåteproduktene i vanlige doser på 400 mg/kg og bestemte blodsukkerverdien etter den kjente metode av Hagerdorn-Jensen over et lengre tidsrom. The benzenesulfonylurea derivatives obtainable by means of the method according to the invention are valuable drugs, which are distinguished by a strong and, above all, long-lasting blood sugar-lowering effect. Their blood sugar-lowering effect could, e.g. determined on rabbits by feeding the process products in regular doses of 400 mg/kg and determining the blood sugar value according to the known method of Hagerdorn-Jensen over a longer period of time.
Således ble det f. eks. fastslått at N-[4-(p-ben-zamidoetyl) -benzolsulfonyl] -N'-cykloheksyl-urinstoff bevirker en maksimal blodsukkersenkning (målt etter 6 timer) på 32 %. Etter 24 timer utgjør denne ennu 32 %. Ved administrering av N-[4-(|3-benzamidoetyl) -benzolsulfonyl] -N'- (4'-metyI cykloheksyl )-urinstof f senkes blodsukkerspeilet maksi-malt omtrent 34 %. Derimot bevirker ved sammen-ligningsforsøk det som oralt antidiabetikum kjente og over hele verden som legemiddel anvendte N-(4-metyl-benzolsulfonyl)- N'-butyl-urinstoff i den ovenfor angitte dosering riktignok en maksimal blodsenkning på 40 %, som imidlertid etter 24 timer igjen er gått tilbake til 0. Ved administrering av den vesentlig lavere dosering på 50 mg/kg på kaniner, som muliggjør en differensiert bestem-melse av den blodsukkersenkende virkning og kommer nærmere den terapeutiske dosering ble det funnet at det nyeN-[4-(p-benzamido-etyl)-benzolsulfonyl]-N'-cykloheksylurinstof f etter 24 timer bevirker en blodsukkersenkning på 17 % og etter 48 timer ennu en på 11 %, og det nye N-[4-(|3-benza-midoetyl) -benzolsulfonyl] -N'- (4'-metylcyklohek-syl)-urinstoff bevirker etter 24 timer sogar ennu en senkning på 21 %, mens den blodsukkersenkende virkning av det kjente N-(4-metyl-benzolsulf onyl)-N'-n-butylurinstoff ved samme dosering etter 24 timer er sunket til 0. Thus it was, for example, determined that N-[4-(p-benzamidoethyl)-benzenesulfonyl]-N'-cyclohexylurea causes a maximum blood glucose lowering (measured after 6 hours) of 32%. After 24 hours, this still amounts to 32%. When N-[4-(|3-benzamidoethyl)-benzenesulfonyl]-N'-(4'-methylcyclohexyl)-urea is administered, the blood sugar level is lowered by a maximum of approximately 34%. On the other hand, in comparative trials, the oral antidiabetic agent known as N-(4-methyl-benzenesulfonyl)-N'-butyl urea, which is used worldwide as a medicine, in the above dosage does indeed cause a maximum blood lowering of 40%, which, however, after 24 hours remaining have returned to 0. When administering the substantially lower dosage of 50 mg/kg to rabbits, which enables a differentiated determination of the blood sugar-lowering effect and comes closer to the therapeutic dosage, it was found that the new N-[4 -(p-benzamido-ethyl)-benzenesulfonyl]-N'-cyclohexylurea f after 24 hours causes a blood sugar lowering of 17% and after 48 hours another of 11%, and the new N-[4-(|3-benza- midoethyl)-benzenesulfonyl]-N'-(4'-methylcyclohexyl)-urea causes after 24 hours even a further lowering of 21%, while the blood sugar-lowering effect of the known N-(4-methyl-benzenesulfonyl)-N '-n-butylurea at the same dosage after 24 hours has dropped to 0.
Videre ble det eksempelvis fastslått at 50 mg/ kg av N-[ 4- ((3-fenoksy-acetamidoetyl) -benzolsulfonyl] -N'-cykloheksyl-urinstoff ved kaniner etter 6 timer bevirker en blodsukkersenkning på 40 %, mens blodsukkerspeilet ved administrering av det kjente N- (4-metyl-benzolsulf onyl) -N'-n-butyl-urinstoff nedsettes med 30 %. Furthermore, it was established, for example, that 50 mg/kg of N-[4-((3-phenoxy-acetamidoethyl)-benzenesulfonyl]-N'-cyclohexyl-urea in rabbits after 6 hours causes a reduction in blood sugar of 40%, while the blood sugar level on administration of the known N-(4-methyl-benzenesulfonyl)-N'-n-butyl urea is reduced by 30%.

Administrerer man N-[4-((3-3-klor-4-metylbenza-mido-etyl) -benzolsulfonyl] -N'- (4-metyl-cykloheksyl)- urinstoff i en dosering på 0,2 mg/kg, N-[4-(|3-3,5-dimetoksybenzamidoetyl) -benzolsulfonyl] - N'-cykloheksyl-urinstoff i en dosering på 0,3 mg/ kg eller N-[4-(p-3,4-diklor-benzamidoetyl)-benzol-sulfonyl] -N'-cykloheksyl-urinstoff i en dosering på 0,3 mg/kg N-[4-(p-2-hydroksybenzamidoetyl)-benzolsulfonyl]-N'-n-butylurinstoff i en dosering på 2 mg/kg eller N-[4-((3-2-hydroksybenzamidoetyl)-benzolsulfonyl]-N'-cykloheksyl-urinstoff i en dosering på 0,15 mg/kg på kaniner, så fastslåes alltid en tydelig blodsukkersenkning. Administering N-[4-((3-3-chloro-4-methylbenza-mido-ethyl)-benzenesulfonyl]-N'-(4-methyl-cyclohexyl)-urea in a dosage of 0.2 mg/kg, N-[4-(|3-3,5-dimethoxybenzamidoethyl)-benzenesulfonyl]-N'-cyclohexyl-urea in a dosage of 0.3 mg/kg or N-[4-(p-3,4-dichloro- benzamidoethyl)-benzenesulfonyl]-N'-cyclohexylurea in a dosage of 0.3 mg/kg N-[4-(p-2-hydroxybenzamidoethyl)-benzenesulfonyl]-N'-n-butylurea in a dosage of 2 mg/kg or N-[4-((3-2-hydroxybenzamidoethyl)-benzenesulfonyl]-N'-cyclohexyl-urea in a dosage of 0.15 mg/kg in rabbits, a clear lowering of blood sugar is always established.
