med en forbindelse med formel R^SH, hvor R"^ har ovennevnte be-tydning, i nærvær av en svak base. with a compound of formula R^SH, where R"^ has the above meaning, in the presence of a weak base.
Ved denne reaksjonen er en svak base en sådan som er tilstrek-kelig til å danne ortokinon-metid og den konjugerte base av det foreliggende merkaptan, dvs. R^S uten å bevirke en retro-aldolspaltning av lasalocidmolekylet. Egnede baser er alkali-metall, f.eks. natrium-eller kaliumkarbonater og bikarbonater, trialkylaminer eller pyridin. Egnede løsningsmidler for denne reaksjonen er alkoholer f.eks. metanol eller etanol, høytkok-ende etere, dioksan eller tetrahydrofuran og etylacetat.

Reaksjonstemperaturen kan ;'variere fra 60°C til det avendte løsningsmiddels tilbakeløps-temperatur hvorved tilbakeløpstemperatur'er foretrukket. ;Forbindelsen med formel III, lasalocid, også kjent som "antibiotikum X-537 A", er et krystallinsk antibiotikum som produ-seres av en streptomycin-organisme fra en jordprøve samlet i Hyde Park, Massachusetts. Lyofiliserte prøver av kulturen som har laboratoriebetegnelsen-X-537, ble deponert-i United States Department of Agriculture, Agriculture Research Service, Northern Utilization Research and Development Division, Peoria, Illinois. Kulturen, som fikk identifikasjonsnummer NRRL 3382 av Agricultural Research Service, ble gjort offentlig tilgjengelig gjennom NRRL. En erstatningskultur som er en nær beslektet stamme av den opprinnelige deponerte kultur NRRL 3382, dvs. har både felles avstamnings- og morfologiske karakteristika, ble deponert hos NRRL under nummeret NRRL 3382R.. Denne kultur er i likhet med den opprinnelige deponerte kultur NRRL 3382 offentlig tilgjengelig. ;Lasalocid (antibiotikum X-537 A) fremstilles ved dyrkning av Streptomyces-organismen i en luftgjennomblåst neddykknings-kultur hvis pH er omtrent nøytral, dvs. ca. 6,5 til 7,5. Mediet får en nitrogenkilde som gjær, et gjærderivat, maismel, bønnemel ol., hvorved soyabønnemel er spesielt foretrukket, ;og en kullhydratkilde som sukker, melasse ol., hvorved råsukker er særlig foretrukket. Fermenteringen utføres ved litt høyere temperaturer, dvs. mellom 25°C og 3 5°C, særlig foretrukket er en inkubasjonstemperatur på ca. 28°C. Etter 4- til 6-dagers inkubering frafiltreres fermenteringsgrøten og antibiotikumet erholdes gjennom ekstraksjon. ;Forbindelsen med formel I har antihypertensiv aktivitet. ;Under anvendelse av en standard som kontroll for sammenlign-ingsformål ble 1-(fenyltio-metyl)-1-dekarboksylasalocid under-søkt med hensyn på antihypertensiv aktivitet. Forsøkene ble gjennomført med enkeltvis orale doser på DOCA-Na-rotte over et tidsrom på 5 dager. Etter 5-dagers perioden ble preparatet jstanset. Blodtrykksmålinger ble utført under 5-dagers periodenj I og deretter daglig etter opphør av preparatet inntil blodtrykk-*i et hadde innstilt seg på utgangsverdien før medikamenteringen. Den daglige dosering var 10 mg/kg. De følgende resultater ble oppnådd: In this reaction, a weak base is one that is sufficient to form the orthoquinone methide and the conjugate base of the present mercaptan, i.e. R 2 S without causing a retro-aldol cleavage of the lasalocid molecule. Suitable bases are alkali metal, e.g. sodium or potassium carbonates and bicarbonates, trialkylamines or pyridine. Suitable solvents for this reaction are alcohols, e.g. methanol or ethanol, high-boiling ethers, dioxane or tetrahydrofuran and ethyl acetate. The reaction temperature can lie between room temperature and reflux temperature, whereby the reflux temperature of the solvent used is preferred. Preferred reaction partners are thiophenol, p-chlorothiophenol, cyclohexyl mercaptan, benzyl mercaptan and mercaptoacetic acid, whereby a compound of formula I is obtained in which R"<*>" is phenyl, p-chlorophenyl, cyclohexyl, benzyl respectively. carboxymethyl. The starting material of formula II can be prepared from lasalocid, a compound of formula; ; by means of a Mannich reaction, more specifically by means of a mixture of a dialkylamine or a cyclic amine such as morpholine, piperidine or pyrrolidine and p-formaldehyde or aqueous formaldehyde. Suitable solvents for this reaction are C₁-C₂ alcohols, toluene, benzene, chlorinated hydrocarbons and ethers such as dioxane or tetrahydrofuran. The reaction temperature can vary from 60°C to the reflux temperature of the solvent used, whereby reflux temperature is preferred. The compound of formula III, lasalocid, also known as "antibiotic X-537 A", is a crystalline antibiotic produced by a streptomycin organism from a soil sample collected in Hyde Park, Massachusetts. Lyophilized samples of the culture bearing the laboratory designation-X-537 were deposited-in the United States Department of Agriculture, Agriculture Research Service, Northern Utilization Research and Development Division, Peoria, Illinois. The cultivar, given the identification number NRRL 3382 by the Agricultural Research Service, was made publicly available through NRRL. A replacement culture which is a closely related strain of the original deposited culture NRRL 3382, i.e. has both common lineage and morphological characteristics, was deposited with NRRL under the number NRRL 3382R.. This culture, like the original deposited culture NRRL 3382, is in the public domain available. ;Lasalocid (antibiotic X-537 A) is produced by growing the Streptomyces organism in an air-blown immersion culture whose pH is approximately neutral, i.e. approx. 6.5 to 7.5. The medium receives a nitrogen source such as yeast, a yeast derivative, maize flour, bean flour etc., whereby soybean flour is particularly preferred, and a carbohydrate source such as sugar, molasses etc., whereby raw sugar is particularly preferred. The fermentation is carried out at slightly higher temperatures, i.e. between 25°C and 35°C, an incubation temperature of approx. 28°C. After a 4- to 6-day incubation, the fermentation mash is filtered off and the antibiotic is obtained through extraction. The compound of formula I has antihypertensive activity. Using a standard as a control for comparison purposes, 1-(phenylthiomethyl)-1-decarboxylasalocid was examined for antihypertensive activity. The experiments were carried out with individual oral doses on DOCA-Na rats over a period of 5 days. After the 5-day period, the preparation was discontinued. Blood pressure measurements were carried out during the 5-day periodj I and then daily after cessation of the preparation until the blood pressure-*i et had adjusted to the starting value before the medication. The daily dosage was 10 mg/kg. The following results were obtained:
1-[(karboksymetyl)tiometyl]-1-dekarboksylasalocid, 1-(p-klor-fenyltiometyl)-1-dekarboksylasalocid, 1-(benzyltiomety1)-1-de-karboksylasalocid og 1-(cykloheksyltiometyl)-1-dekarboksylasa-locid ble likeledes undersøkt. 1-[(carboxymethyl)thiomethyl]-1-decarboxylasaloside, 1-(p-chloro-phenylthiomethyl)-1-decarboxylasaloside, 1-(benzylthiomethyl)-1-decarboxylasaloside and 1-(cyclohexylthiomethyl)-1-decarboxylasaloside was also investigated.
Resultatene er gjengitt i den etterfølgende tabell. Av resultatene fremgår at under påbegynnelse og varighet av antihyper-tensive virkninger består forskjeller, men at de ovenfor nevnte forbindelser har en antihypertensiv aktivitet når man sammen-ligner blodtrykket 1. dag med 5. dag etter opphør av medikament-et. The results are reproduced in the following table. The results show that there are differences in the onset and duration of antihypertensive effects, but that the above-mentioned compounds have an antihypertensive activity when blood pressure is compared on the 1st day with the 5th day after discontinuation of the drug.

av det osmotiske trykk og puffer anvendes som er vanlig i slike preparater. of the osmotic pressure and buffers are used which are common in such preparations.
Det har vist seg at den subakutte orale administrering for behandling av høyt trykk hos varmblodige vesener f.eks. DOCA-Na-hypertensiv rotte, dvs. en dosering opp til 5 dager med derpå følgende opphør av preparatet er mest. virksomt, når doserings-området ligger mellom ca. 5 mg/kg og 100 mg/kg, spesielt mellom 5 mg/kg og 10 mg/kg. Den kroniske orale administrering, dvs. It has been shown that the subacute oral administration for the treatment of high pressure in warm-blooded beings e.g. DOCA-Na hypertensive rat, i.e. a dosage of up to 5 days followed by cessation of the preparation is the most. effectively, when the dosage range is between approx. 5 mg/kg and 100 mg/kg, especially between 5 mg/kg and 10 mg/kg. The chronic oral administration, i.e.
en dosering utover 5 dager, er mest virksom når et lavt doserings-nivå anvendes, dvs. lavere enn 0,1 mg/kg daglig, f.eks. 0,01 mg/kg til ca. 5 mg/kg pr. dag. De forannevnte beskrevne, doserings-planer kan også anvendes ved behandling av andre kardiovaskulære a dosage beyond 5 days is most effective when a low dosage level is used, i.e. lower than 0.1 mg/kg daily, e.g. 0.01 mg/kg to approx. 5 mg/kg per day. The dosage plans described above can also be used in the treatment of other cardiovascular diseases
symptomer som Angina pectoris, Claudicatio og nedsatt blodgjennom-strømning i hjernen. Ved doseringen er doseringsskjemaet for den kroniske administrering særlig foretrukket, dvs. en dosering fra mindre enn 0,1 mg/kg pr. dag opp til ca. 5 mg/kg pr. dag. symptoms such as Angina pectoris, Claudication and reduced blood flow in the brain. For the dosage, the dosage form for the chronic administration is particularly preferred, i.e. a dosage from less than 0.1 mg/kg per day up to approx. 5 mg/kg per day.
EKSEMPEL 1 EXAMPLE 1
Streptomycesstammen NRRL 3382 R ble dyrket i beluftet dypkultur i rystekolber. Substratet ble ved tilsetning av kalilut innstilt på pH 6,5 - 7,5 og deretter sterilisert. I en fermenter-ingstank ble substratet som inneholdt 2% soyabønnemel, 2% råsukker, 0,5% maissvellevann og 0,1% K^IPO^ podet med 5 - 10% The Streptomyces strain NRRL 3382 R was grown in aerated deep culture in shake flasks. The substrate was adjusted to pH 6.5 - 7.5 by the addition of potassium hydroxide and then sterilized. In a fermentation tank, the substrate containing 2% soybean meal, 2% raw sugar, 0.5% corn-swell water and 0.1% K^IPO^ was inoculated with 5 - 10%
av et inokulum fra en 3 dager gammel dypkultur. Fermenteringen ble utført ved 28° under positivt lufttrykk hvorunder pr. min-utt og pr. 150 - 300 1 væske en luftstrøm på 140-280 1 opprett-holdt. Kulturen ble høstet etter 4 til 6 dagers fermentering, filtrert og antibiotikumet utskilt ved ekstraksjon som følger: 204 1 kulturløsning ble filtrert og den fuktige filterkaken ble oppslemmet i 100 1 butylacetat og rørt natten over ved romtemperatur. Blandingen ble så filtrert og det vandige skiktet ad-skilt og kastet. Butylacetatløsningen som hadde 30 millioner Bazillus E-enheter, ble konsentrert under redusert trykk til 3 1, vasket med 10%-ig natriumkarbonatløsning og tørket over natriumsulfat. of an inoculum from a 3-day-old deep culture. The fermentation was carried out at 28° under positive air pressure during which per min-out and per 150 - 300 1 liquid an air flow of 140-280 1 maintained. The culture was harvested after 4 to 6 days of fermentation, filtered and the antibiotic separated by extraction as follows: 204 L of culture solution was filtered and the moist filter cake was slurried in 100 L of butyl acetate and stirred overnight at room temperature. The mixture was then filtered and the aqueous layer separated and discarded. The butyl acetate solution having 30 million Bazillus E units was concentrated under reduced pressure to 3 L, washed with 10% sodium carbonate solution and dried over sodium sulfate.
Etter ytterligere inndampning til 300 ml og fortynning med 350 ml petroleter (kokepunkt 50 - 60°) ble 41 g fast stoff med et innhold på 25 millioner;.Bazillus E-enheter isolert. Dette faste stoffet ble så ekstrahert i et Soxhletapparat 40 timer med 4 1 petroleter (kokepunkt 50 - 60°). Ekstraktet ble bragt til tørr-het under redusert trykk, den krystallinske resten oppslemmet i petroleter og filtrert og ga 24,49 g av en blanding av 3-metyl-6-[7-etyl-4-hydroksy-3,5-dimetyl-6-okso-7-Z5-etyl-3-metyl-5-(5-etyl-5-hydroksy-6-metyl-2-tetrahydropyranyl)-2-tetrahydrofuryl7~heptyl]salicylsyre(Lasalocid) og saltet derav. Moderluten ga ytterligere 5,73 g av antibiotikumet. After further evaporation to 300 ml and dilution with 350 ml of petroleum ether (boiling point 50-60°), 41 g of solid containing 25 million Bazillus E units were isolated. This solid was then extracted in a Soxhlet apparatus for 40 hours with 4 l of petroleum ether (boiling point 50 - 60°). The extract was brought to dryness under reduced pressure, the crystalline residue slurried in petroleum ether and filtered to give 24.49 g of a mixture of 3-methyl-6-[7-ethyl-4-hydroxy-3,5-dimethyl- 6-oxo-7-Z5-ethyl-3-methyl-5-(5-ethyl-5-hydroxy-6-methyl-2-tetrahydropyranyl)-2-tetrahydrofuryl7~heptyl]salicylic acid (Lasalocid) and its salt. The mother liquor gave an additional 5.73 g of the antibiotic.
Etter omkrystallisering fr.a. eter-petroleter ble det natriumhold-ige materialet løst i eter og vasket med fortynnet svovelsyre for å overføre det i den frie syren. Fjerning av eteren ga en oljeaktig rest som krystalliserte fra etanol og ga rent Lasalocid-etanolåt. Flere omkrystalliseringer fra etanol endret ikke smeltepunktet som forble uskarpt ved 100-109°C. After recrystallization from ether-petroleum ether, the sodium-containing material was dissolved in ether and washed with dilute sulfuric acid to transfer it into the free acid. Removal of the ether gave an oily residue which crystallized from ethanol to give pure Lasalocid ethanolate. Several recrystallizations from ethanol did not change the melting point which remained indistinct at 100-109°C.

Eksempel2I En blanding av 5 g Lasalocid-etanolat, 2,5 g paraformaldehyd og 2,5 g dietylamin i 200 ml toluen ble oppvarmet 90 minutter under røring ved tilbakeløp. Under tilbakeløpsoppvarmingen ble vann-et samlet i en felle. Den erholdte løsningen ble fortynnet med eter, vasket med vann og med sterkt fortynnet (ca. 0,05 N) saltsyre. Det organiske skiktet ble tørket, filtrert og løsnings-midlet fjernet under redusert trykk, hvorved en lysegul (mange ganger fargeløs harpiks) ble tilbake. Denne rå Mannich-basen, 1-(dietylaminometyl)-1-dekarboksylasalocid, inneholdt toluen, men ble anvendt direkte i det neste trinn. Example 2I A mixture of 5 g of Lasalocid ethanolate, 2.5 g of paraformaldehyde and 2.5 g of diethylamine in 200 ml of toluene was heated for 90 minutes with stirring at reflux. During reflux heating, the water was collected in a trap. The solution obtained was diluted with ether, washed with water and with highly diluted (approx. 0.05 N) hydrochloric acid. The organic layer was dried, filtered and the solvent removed under reduced pressure, whereby a pale yellow (many times colorless resin) remained. This crude Mannich base, 1-(diethylaminomethyl)-1-decarboxylasaloside, contained toluene but was used directly in the next step.
Eksempel 3 Example 3
En løsning av 9,7 g av den i eksempel 2 fremstilte Mannich-base, 4,5 ml tiofenol og 4 mg trietylamin i 125 ml etanol ble oppvarmet 18 timer ved tilbakeløp. Løsningsmidlet ble avdampet under redusert trykk og resten tatt opp i'metylenklorid. Etter vask-ing med vann og fortynnet natriumkarbonatløsning ble løsningen tørket og løsningsmidlet avdampet. Råproduktet ble renset ved kromatografi på 200 g kiselgel. Med heksan/etylacetat (8:1) ble tiofenol og med heksan/etylacetat (6:1) produktet, 1-(fenyl-tio-metyl)-1-dekarboksylasalocid eluert. Avdampning av løsningsmid-let, til slutt under redusert trykk, ga et fargeløst skum. A solution of 9.7 g of the Mannich base prepared in example 2, 4.5 ml of thiophenol and 4 mg of triethylamine in 125 ml of ethanol was heated for 18 hours at reflux. The solvent was evaporated under reduced pressure and the residue taken up in methylene chloride. After washing with water and dilute sodium carbonate solution, the solution was dried and the solvent was evaporated. The crude product was purified by chromatography on 200 g of silica gel. With hexane/ethyl acetate (8:1) thiophenol and with hexane/ethyl acetate (6:1) the product, 1-(phenyl-thio-methyl)-1-decarboxylasaloside, were eluted. Evaporation of the solvent, finally under reduced pressure, gave a colorless foam.

2 g p-klortiofenol og 2 ml trietylamin i 50 ml etanol ble oppvarmet 18 timer ved tilbakeløp. Da reaksjonen ikke var full-stendig (tynnskiktkromatogram) ble ytterligere 2 g p-klortiofenol og 2 ml trietylamin tilsatt og tilbakeløpsoppvarmingen fort-satte i 24 timer. Etter avkjøling ble løsningsmidlet aminet avdampet under redusert trykk og resten tatt opp i metylenklorid. Denne løsningen ble vasket .med vandig natriumkarbonatløsning, tørket over natriumsulfat og inndampet. 2 g of p-chlorothiophenol and 2 ml of triethylamine in 50 ml of ethanol were heated for 18 hours at reflux. When the reaction was not complete (thin-layer chromatogram), a further 2 g of p-chlorothiophenol and 2 ml of triethylamine were added and reflux heating continued for 24 hours. After cooling, the solvent amine was evaporated under reduced pressure and the residue taken up in methylene chloride. This solution was washed with aqueous sodium carbonate solution, dried over sodium sulfate and evaporated.
Resten var en blanding, hovedsaklig av p<->klortiofenol og den ønskede tioeter, 1-(p-klorfenyltiometyl)-1-dekarboksylasalocid, som ble kromatografert med benzen/etylacetat (2:1) som eluerings-middel. Fraksjonene som inneholdt produktet (tynnskiktkromato-J grafi) ble slått sammen og ga ved inndampning et fargeløst fast skum som ble flytende ved 42-46°C. The residue was a mixture, mainly of p<->chlorothiophenol and the desired thioether, 1-(p-chlorophenylthiomethyl)-1-decarboxylasaloside, which was chromatographed with benzene/ethyl acetate (2:1) as eluent. The fractions containing the product (thin layer chromatography) were combined and, on evaporation, gave a colorless solid foam which liquefied at 42-46°C.

Etter kjøling og avdampning av løsnings-midlet under redusert trykk ble resten kromatografert på kis.el-gel med heksan/etylacetat (5:1). Fraksjonene som inneholdt produktet ble forenet og inndampet. Det herved erholdte produkt var forurenset av små mengder benzylmerkaptan og ble renset ved preparativ skiktkromatografi på 6 20 x 20 cm kiselgelplater med heksan/etylacetat (4:1). Det rene produkt, 1-(benzyltiomety1-1-dekarboksylasalocid, ble erholdt som fargeløst fast skum. 4v5 g of 1-(diethylaminomethyl)-1-decarboxylasaloside, 5 ml of benzyl mercaptan and 5 ml of triethylamine were heated under reflux overnight in 100 ml of ethanol. After cooling and evaporation of the solvent under reduced pressure, the residue was chromatographed on silica gel with hexane/ethyl acetate (5:1). The fractions containing the product were combined and evaporated. The product thus obtained was contaminated by small amounts of benzyl mercaptan and was purified by preparative layer chromatography on 6 20 x 20 cm silica gel plates with hexane/ethyl acetate (4:1). The pure product, 1-(benzylthiomethyl-1-decarboxylasaloside), was obtained as a colorless solid foam.
