The invention relates only to such compounds which in these centers exhibit trans-configuration, i.e. the lactam ring as a substituent at C-4 and the OH group at C-3 are always oriented trans relative to each other.

30 Ovenstående definition af X betyder, at lactamringen også indeholder et chiralt C-atom. Opfindelsen angår således både forbindelser med R- og S-konfigurerede centre. Det samme gælder, når R1, R2, R3 eller R4 indeholder asymmetri-centre. Forbindelserne kan da foreligge som optiske isomere, 35 som diastereoisomere, som racemater eller som en blanding heraf.The above definition of X means that the lactam ring also contains a chiral C atom. The invention thus relates to both connections with R- and S-configured centers. The same is true when R1, R2, R3 or R4 contain asymmetry centers. The compounds may then be available as optical isomers, as diastereoisomers, as racemates or as a mixture thereof.

15 I J. Med. Chem. 29, 2194-2201 (1986), er beskrevet de N-benzopyranyllactamer, som ligger nærmest ved forbindelserne ifølge opfindelsen. En stor del af disse forbindelser er også beskrevet i forskellige offentliggørelsesskrifter, blandt hvilke skal nævnes EP-A nr. 107.423, 120.427, 076.075 20 og 120.428.In J. Med. Chem. 29, 2194-2201 (1986) discloses the N-benzopyranyl lactams closest to the compounds of the invention. Much of these compounds are also disclosed in various disclosures, including EP-A Nos. 107,423, 120,427, 076,075 and 120,428.

Om disse forbindelser ved man, at de er i stand til at sænke et sygeligt forhøjet blodtryk, idet de afslapper den glatte karmuskulatur og beskytter den mod pressorpåvirk-ninger eller kan gøre den ufølsom.About these compounds, they are known to be capable of lowering morbidly elevated blood pressure, relaxing the smooth vasculature and protecting it from compressor effects or making it insensitive.

25 Forbindelserne med formlen I ifølge opfindelsen udgør en ny stofklasse, som først og fremmest adskiller sig fra de kendte, ved at de i den lactamring, som er substituent på C-4 i chromansystemet, bærer en c1_2-alkylsubstituent. Denne substituering fører ved sammenligning med den kendte, 30 usubstituerede forbindelse i nogle tilfælde til en formindskelse af den akutte toksicitet.The compounds of formula I according to the invention constitute a new class of substances which differs primarily from the known ones in that they carry in the lactam ring which is substituent on C-4 in the chromane system a C1-2 alkyl substituent. This substitution, when compared to the known, unsubstituted compound, sometimes reduces acute toxicity.

Forbindelserne ifølge opfindelsen med formlen I udviser en kraftig afslappende virkning på ureteren. Derfor er sådanne forbindelser værdifulde terapeutika ved behand-35 lingen af urinlederkolik og ved lithotripsibehandling.

25 Dersom forbindelserne med formlen I fremstilles ved metoderne (a) eller (b), sker dette ved, at forbindelserne IV eller II i et egnet opløsningsmiddel, fortrinsvis i dipolære, aprote opløsningsmidler, såsom dimethylsulfoxid eller THF, omsættes med lactamerne med formlen III, fortrins-30 vis under indflydelse af baser, såsom natriumhydrid, K-tert.-butylat eller lignende, med henblik på lactam-N-alkyleringer af kendte, egnede baser. Reaktionstemperaturen kan herved varieres indenfor et bredt område, men fortrinsvis arbejdes der mellem O'C og stuetemperatur. Ved anvendelse af racemiske 35 lactamer med formlen III eller optisk ensartede lactamer med formlen III (når X indeholder et usymmetrisk substitueret DK 167440 Bl 5 C-atom) fås i det mindste 2 nye produkter med formlen I.If the compounds of formula I are prepared by methods (a) or (b), this is done by reacting compounds IV or II in a suitable solvent, preferably in dipolar aprotic solvents such as dimethylsulfoxide or THF, with the lactams of formula III, preferably under the influence of bases such as sodium hydride, K-tert-butylate or the like, for lactam N-alkylations of known suitable bases. The reaction temperature can hereby be varied within a wide range, but preferably between 0 ° C and room temperature.

De pågældende produkter kan derpå ved gængse fysiske undersøgelser, såsom røntgenstrukturanalyse eller NMR-spektroskopi, grupperes under de pågældende samlede konfigurationer. Optisk ensartede, dvs. enantiomerrene, forbindelser med formlen I kan fås ved efterfølgende race-10 matspaltning. Hvis der allerede anvendes enantiomerrene lactamer med formlen III, fås de diastereoisomere forbindelser med formlen I ligeledes i enantiomeren form, og en racematspaltning bliver overflødig.These products can be separated by conventional methods, such as crystallization or chromatography, and in many cases a combination of these two methods has proved advantageous. The products in question can then be grouped under the usual overall configurations by conventional physical studies, such as X-ray structure analysis or NMR spectroscopy. Optically uniform, i.e. enantiomerically, compounds of formula I can be obtained by subsequent racemate digestion. If enantiomerically pure lactams of formula III are already used, the diastereoisomeric compounds of formula I are also obtained in enantiomeric form and a racemate cleavage becomes redundant.

Lactamer med formlen III er i mange tilfælde kendt 15 eller kan let fremstilles ifølge metoder, der er kendt fra litteraturen. Også bromhydrinerne med formlen II og epoxider-ne med formlen IV er i mange tilfælde kendt [jfr. de ovenfor anførte offentliggørelsesskrifter eller J. Med. Chem. 29, 2194-2201 (1986)] eller kan fremstilles analogt med de der 20 anførte metoder. Sådanne forbindelser med formlen II og IV, hvor R1 er -S02-phenyl, er hidtil ukendte. De kan f.eks. fremstilles på følgende måde: 2,3-Dihydro-2H-benzo[b]pyran-4-oner med formlenIn many cases, lactams of formula III are known or can be readily prepared by methods known in the literature.

Indflydelse på KC1-inducerede, rytmiske kontraktioner på marsvine-uretere in vitro.Influence of KC1-induced rhythmic contractions on guinea pig ureters in vitro.

Metode: Hanmarsvin aflives ved nakkeslag og åreladning 30 fra carotiderne. Begge uretere fjernes straks, idet området nær ved nyrebækkenet undgås på grund af den pacer-aktivitet, der findes der. Derpå befries 2 cm lange stykker i en petriskål, som indeholder Tyrode-opløsning, for bindevæv og ophænges hver især med en forspænding på 4,9 mN (= 0,5 p) i 35 et 25 ml organbad (Fa. Rhema Labortechnik, Hofheim). Organbadet indeholder en Tyrode-opløsning, der holdes på 37eC, 14 som gennembobles med carbogen (95% 02, 5% C02)/ og som har følgende sammensætning (mmol/liter) : NaCl 137, KC1 2,68,Method: Male guinea pigs are sacrificed by neck stroke and yearly charge 30 from the carotids. Both ureters are removed immediately, avoiding the area near the renal pelvis due to the pacer activity found there. Then, 2 cm long pieces in a Petri dish containing Tyrode solution are frozen for connective tissue and each suspended with a bias of 4.9 mN (= 0.5 p) in a 25 ml organ bath (Fa. Rhema Labortechnik, Hofheim ). The organ bath contains a Tyrode solution maintained at 37 ° C, 14 which is bubbled with the carbogen (95% O 2, 5% CO 2) / and having the following composition (mmol / liter): NaCl 137, KCl 2.68,

MgS04 1,05, CaCl2 1,8, NaH2P04 0,41, NaHC03 11,9 og glucose 5,55.MgSO4 1.05, CaCl2 1.8, NaH2 PO4 0.41, NaHCO3 11.9 and glucose 5.55.

5 Kontraktionerne måles isometrisk under anvendelse af5 The contractions are measured isometrically using

Gould/Statham UC2-afgivere. Efter en ækvilibreringstid på mindst 15 minutter sættes der KC1 til organbadet, idet der nås en koncentration på 4 x 10“2 mol/liter. Agonisten forbliver i 2 minutter i badet, hvorved der optræder fasekon-10 traktioner, uden at dette bevirker en nævneværdig stigning af grundspændingen. Derefter skylles der i l minut, hvorpå de rytmiske kontraktioner straks ophører. Efter endnu en gang agonisttilsætning og skylning sættes prøveforbindelsen (benzopyran-derivat) til organbadet (i form af en opløsning 15 i 0,1 ml ethanol; s lutkoncentrat ionerne er i alle tilfælde 10“7 mol/liter), og man afventer en indvirkningstid på ét minut, før der tilsættes KC1. Efter den følgende skylningsoperation følger 2 afsluttende agonisttilsætning/skylningsprocedurer. Ud fra perioderne på hver 2 minutter under ind-20 virkning af KC1 bestemmes følgende parametre; 1. gennemsnitlig kontraktionskraft, 2; kontraktionernes frekvens og 3. produktet af gennemsnitlig kontraktionskraft og frekvens.Gould / Statham UC2 emitters. After an equilibration time of at least 15 minutes, KC1 is added to the organ bath, reaching a concentration of 4 x 10 “2 mol / liter. The agonist stays in the bath for 2 minutes, resulting in phase contractions, without causing a significant increase in the fundamental voltage. Then rinse for 1 minute, which immediately stops the rhythmic contractions. After agonist addition and rinsing again, the test compound (benzopyran derivative) is added to the organ bath (in the form of a solution 15 in 0.1 ml of ethanol; for one minute before adding KC1. Following the following rinse operation, 2 final agonist addition / rinse procedures follow. From the periods of every 2 minutes under the influence of KC1, the following parameters are determined; 1. average contraction power, 2; frequency of contractions and 3. the product of average contracting power and frequency.

Udelukkelseskriterier er gennemsnitlige kontraktionskræfter under 4 mN eller frekvenser under 2/min. ved mere 25 end én af fire perioder, i hvilke kun agonisten KC1 findes i badet. Man bedømmer den procentvise hæmning under prøvestof sammenlignet med middelværdien af de to forforsøg.Exclusion criteria are average contraction forces below 4 mN or frequencies below 2 / min. at more than 25 of one of four periods in which only the agonist KC1 is present in the bath. The percent inhibition under test substance is evaluated compared to the mean of the two tests.

Foruden den aritmetiske gennemsnitsværdi (x) udregnes standardafvigelsen (SEM).In addition to the arithmetic mean value (x), the standard deviation (SEM) is calculated.
