Description
Endotelin je peptid izgrađen od 21 amino kiseline, kojeg sintetizira i oslobađa vaskularni endotel. Endotelin postoji u tri izomerna oblika, ET-1, ET-2 i ET-3. Kako se ovdje rabi, pojam “endotelin” ili “ET” odnosi se na jedan ili na sve izomerne oblike endotelina. Endotelin je jaki vazokonstriktor i snažno djeluje na tonus krvnih žila. Poznato je, da tu vazokonstrikciju uzrokuje vezanje endotelina na njegov receptor (Nature, 332, 411-415, 1988; FEBS Letters, 231, 440-444, 1988 i Biochem. Biophys. Res. Commun., 154, (1988), 868-875). Endothelin is a peptide made of 21 amino acids, which is synthesized and released by the vascular endothelium. Endothelin exists in three isomeric forms, ET-1, ET-2 and ET-3. As used herein, the term “endothelin” or “ET” refers to one or all of the isomeric forms of endothelin. Endothelin is a strong vasoconstrictor and has a strong effect on blood vessel tone. It is known that this vasoconstriction is caused by the binding of endothelin to its receptor (Nature, 332, 411-415, 1988; FEBS Letters, 231, 440-444, 1988 and Biochem. Biophys. Res. Commun., 154, (1988), 868 -875).
Povišeno ili nenormalno oslobađanje endotelina uzrokuje trajno sužavanje u perifernim, renalnim i cerebralnim krvnim žilama, koje može dovesti do zdravstvenih poremećaja. Iz literature je poznato da je endotelin uključen u brojne zdravstvene poremećaje. To su hipertenzija, akutni miokardijalni infarkt, plućna hipertenzija, Raynaudov sindrom, cerebralne vazospazme, udar kapi, benigna hipertrofija prostate, ateroskleroza, astma i rak prosta (J. Vascular Med. Biology 2, (1990) 207, J. Am. Med. Association 264, (1990) 2868, Nature 344, (1990) 114, N. Engl. J. Med. 322, (1989) 205, N. Engl. J. Med. 328, (1993) 1732, Nephron 66, (1994) 373, Stroke 25, (1994) 904, Nature 365, (1993) 759, J. Mol. Cell. Cardiol. 27, (1995) A234, Cancer Research 56, (1996) 663. Elevated or abnormal release of endothelin causes permanent narrowing in peripheral, renal and cerebral blood vessels, which can lead to health disorders. It is known from the literature that endothelin is involved in numerous health disorders. These are hypertension, acute myocardial infarction, pulmonary hypertension, Raynaud's syndrome, cerebral vasospasm, stroke, benign prostatic hypertrophy, atherosclerosis, asthma and prostate cancer (J. Vascular Med. Biology 2, (1990) 207, J. Am. Med. Association 264, (1990) 2868, Nature 344, (1990) 114, N. Engl. J. Med. 322, (1989) 205, N. Engl. J. Med. 328, (1993) 1732, Nephron 66, ( 1994) 373, Stroke 25, (1994) 904, Nature 365, (1993) 759, J. Mol. Cell. Cardiol. 27, (1995) A234, Cancer Research 56, (1996) 663.
Zasada su u literaturi opisana najmanje dva podtipa endotelin-receptora, ETA i ETB receptori (Nature 348, (1990) 730, Nature 348, (1990) 732). Prema tome, tvari koje inhibiraju vezanje endotelina na jedan ili na obadva receptora, antagoniziraju fiziološke efekte endotelina i stoga predstavljaju dragocjene lijekove. So far, at least two subtypes of endothelin receptors, ETA and ETB receptors, have been described in the literature (Nature 348, (1990) 730, Nature 348, (1990) 732). Therefore, substances that inhibit the binding of endothelin to one or both receptors antagonize the physiological effects of endothelin and therefore represent valuable drugs.
Miješani endotelin receptor antagonisti su oni spojevi koji se vežu s približno jednakim afinitetom na ETA i na ETB receptore. Približno jednak afinitet za receptore postoji kad je omjer afiniteta ETA:ETB veći od 0,05, ponajprije veći od 0,1, i manji od 20, ponajprije manji od 10. Mixed endothelin receptor antagonists are those compounds that bind with approximately equal affinity to ETA and ETB receptors. Approximately equal receptor affinity exists when the ETA:ETB affinity ratio is greater than 0.05, preferably greater than 0.1, and less than 20, preferably less than 10.
U patentnoj prijavi DE 19636046.3 opisani su miješani ЕТA/ЕТB receptor antagonisti. Za te spojeve važna je skupina razmaka Q (vidi formulu XX), koja duljinom odgovara lancu C2-C4-alkila. Patent application DE 19636046.3 describes mixed ETA/ETB receptor antagonists. Important for these compounds is the spacing group Q (see formula XX), which corresponds in length to the C2-C4-alkyl chain.
[image] [image]
Miješani receptor antagonisti su također dobiveni sa skupinom razmaka Q = COCR7R8 (vidi formulu I). Mixed receptor antagonists have also been obtained with the spacer group Q = COCR7R8 (see formula I).
Zadatak izuma je identificirati spojeve koji se s približno jednakim afinitetom vežu na ЕТA i ЕТB receptor i koji imaju bolja svojstva u usporedbi s već poznatim miješanim endotelin receptor antagonistima. The task of the invention is to identify compounds that bind with approximately equal affinity to the ETA and ETB receptor and that have better properties compared to already known mixed endothelin receptor antagonists.

Prednosni su takovi pred-lijekovi u kojima se oslobađanje odvija pod uvjetima koji vladaju u određenim dijelovima tijela, npr. u želucu, crijevima, krvotoku, jetri. Preferable are such prodrugs in which the release takes place under the conditions prevailing in certain parts of the body, eg in the stomach, intestines, bloodstream, liver.
Spojevi I i također intermedijati za njihovu proizvodnju, kao što su npr. II, III, IV, V i VI, mogu imati jedan ili više asimetrično supstituiranih ugljikovih atoma. Takovi spojevi mogu postojati kao čisti enantiomeri, odnosno kao čisti diastereomeri ili kao njihova smjesa. Pri upotrebi kao aktivne tvari, prednost se daje upotrebi enantiomerno čistog spoja. Compounds I and also intermediates for their production, such as II, III, IV, V and VI, may have one or more asymmetrically substituted carbon atoms. Such compounds can exist as pure enantiomers, i.e. as pure diastereomers or as a mixture thereof. When used as an active substance, preference is given to using an enantiomerically pure compound.

Daljnja mogućnost za dobivanje enantiomerno čistih spojeva formule IV je klasično rastavljanje s prikladno enantiomerno čistim bazama upotrebom racemičnih ili diastereomernih spojeva formule IV. Prikladne baze te vrste jesu, na primjer, 4-klorfeniletilamin i baze spomenute u WO 96/11914. A further possibility for obtaining enantiomerically pure compounds of formula IV is classical resolution with suitable enantiomerically pure bases using racemic or diastereomeric compounds of formula IV. Suitable bases of this type are, for example, 4-chlorophenylethylamine and the bases mentioned in WO 96/11914.

Reakcija se odvija ponajprije u inertnom otapalu ili u sredstvu za razrjeđivanje, uz dodatak prikladne baze, tj. baze koja uzrokuje deprotoniranje intermedijarnog proizvoda IV, pri temperaturi u području od sobne temperature do vrelišta otapala. In formula V, R 16 is halogen or R 117 -SO 2 -, where R 17 can be C 1 -C 4 -alkyl, C 1 -C 4 -haloalkyl or phenyl. In addition, at least one of the ring members X or Y or Z is nitrogen.

Spojevi tipa VI, gdje R1 predstavlja COOH, mogu se dobiti izravno tako da se intermedijat IV, u kojem R1 predstavlja COOH, deprotonira s dva ekvivalenta prikladne baze i reakcijom sa spojevima opće formule V. Ta se reakcija također odvija u inertnom otapalu i pri temperaturi u području od sobne temperature do vrelišta otapala. Compounds of type VI, where R1 is COOH, can be obtained directly by deprotonating intermediate IV, where R1 is COOH, with two equivalents of a suitable base and reacting with compounds of the general formula V.

The compounds according to the invention, in which the substituents have the meanings given under the general formula I, can be finally produced by removing the keto protecting group in the compounds of the formula VI. In the case of ethylene glycol acetals, this can be done by acid hydrolysis.

Spojevi formule I mogu se proizvesti također i tako da se pođe od odgovarajućih karboksilnih kiselina, tj. spojeva formule I u kojoj R1 predstavlja COOH, i oni se najprije na uobičajen način prevedu u aktivirani oblik, kao što je kiselinski halogenid, anhidrid ili imidazolid, a potonji zatim reagira s odgovarajućim hidroksilnim spojem HOR9. Ta reakcija se može provesti u uobičajenim otapalima i često je potreban dodatak baze, i u tom slučaju su prikladne gore spomenute. Ta dva stupnja mogu se također pojednostavniti, na primjer, tako da se karboksilnu kiselinu pusti djelovati na hidroksilni spoj u prisutnosti sredstva za dehidrataciju, kao što je karbodiimid. Compounds of formula I can also be produced by starting from the corresponding carboxylic acids, i.e. compounds of formula I in which R1 represents COOH, and they are first converted in the usual way into an activated form, such as an acid halide, anhydride or imidazolide, and the latter then reacts with the corresponding hydroxyl compound HOR9. This reaction can be carried out in common solvents and often requires the addition of a base, in which case those mentioned above are suitable. These two steps can also be simplified, for example, by allowing the carboxylic acid to act on the hydroxyl compound in the presence of a dehydrating agent, such as carbodiimide.
Osim toga, spojevi formule I mogu se također proizvesti i tako da se pođe od soli odgovarajućih karboksilnih kiselina, tj. spojeva formule I u kojoj R1 predstavlja skupinu COOM, pri čemu M može biti kation alkalijskog metala ili ekvivalent kationa zemno alkalijskog metala. Te soli mogu reagirati s mnogim spojevima formule R9-A, pri čemu A predstavlja uobičajenu nukleofilnu otpusnu skupinu, primjerice halogen, kao klor, brom, jod, ili aril- ili alkilsulfonil prema potrebi supstituiran s halogenim, alkilom ili s halogenalkilom, kao npr. toluensulfonil i metilsulfonil, ili s drugom ekvivalentnom otpusnom skupinom. Spojevi formule R9-A s reaktivnim supstituentom A su poznati ili se lako mogu dobiti na osnovi općeg stručnog znanja. Ta se reakcija može provesti u uobičajenim otapalima i odvija se prednosno uz dodatak baze, i u tom slučaju su prikladne gore navedene. In addition, the compounds of formula I can also be produced by starting from salts of the corresponding carboxylic acids, i.e. compounds of formula I in which R1 represents the group COOM, where M can be an alkali metal cation or the equivalent of an alkaline earth metal cation. These salts can react with many compounds of the formula R9-A, where A represents a common nucleophilic leaving group, for example halogen, such as chlorine, bromine, iodine, or aryl- or alkylsulfonyl optionally substituted with halogen, alkyl or haloalkyl, such as e.g. toluenesulfonyl and methylsulfonyl, or with another equivalent leaving group. Compounds of formula R9-A with a reactive substituent A are known or can be easily obtained based on general knowledge of the art. This reaction can be carried out in common solvents and takes place preferably with the addition of a base, in which case the above are suitable.
U nekim slučajevima za pripravljanje spojeva I prema izumu moraju se primijeniti općenito poznati postupci sa zaštitnim skupinama. Ako, na primjer, R6 predstavlja 4-hidroksifenil, tada se hidroksilnu skupinu može najprije zaštititi kao benzilni eter, koji se zatim odcjepljuje u prikladnom stupnju reakcije. In some cases, for the preparation of compounds I according to the invention, generally known procedures with protecting groups must be applied. If, for example, R 6 represents 4-hydroxyphenyl, then the hydroxyl group may first be protected as a benzyl ether, which is then cleaved off in an appropriate reaction step.
Spojevi formule I, u kojoj R1 predstavlja tetrazol, mogu se proizvesti kako je opisano u WO 96/11914. Compounds of formula I, wherein R 1 is tetrazole, can be prepared as described in WO 96/11914.

Proučavanje vezanja receptora Study of receptor binding
Za proučavanje vezanja upotrijebljene su klonirane CHO-stanice koje umnažaju humani ETA- ili ETB-receptor. Cloned CHO cells amplifying the human ETA or ETB receptor were used for binding studies.
Priprava membrana Preparation of membranes
CHO-stanice, koje umnažaju ETA- ili ETB-receptor, rasle su u DMEM NUT MIX F12-mediju (Gibco, br. 21331-020) s 10% fetalnog telećeg seruma (PAA Laboratories GmbH, Linz, br. A15-022), 1 mM glutamina (Gibco br. 25030-024), 100 U/ml penicilina i 100 μg/ml streptomicina (Gibco, Sigma br. P-0781). Nakon 48 sati stanice su isprane s PBS-om i inkubirane 5 minuta pri 37oC s PBS-om koji je sadržavao 0,05% tripsina. Smjesa je zatim neutralizirana s medijem i stanice su skupljene centrifugiranjem pri 300 x g. CHO cells expressing the ETA or ETB receptor were grown in DMEM NUT MIX F12 medium (Gibco, No. 21331-020) with 10% fetal calf serum (PAA Laboratories GmbH, Linz, No. A15-022). , 1 mM glutamine (Gibco No. 25030-024), 100 U/ml penicillin, and 100 μg/ml streptomycin (Gibco, Sigma No. P-0781). After 48 hours the cells were washed with PBS and incubated for 5 minutes at 37oC with PBS containing 0.05% trypsin. The mixture was then neutralized with medium and the cells were harvested by centrifugation at 300 x g.
Za pripravljanje membrana stanice su namještene na koncentraciju od 108 stanica/ml pufera (50 ml tris HCl pufer, pH 7,4) i zatim su dezintegrirane ultrazvukom (Branson Sonifier 250, 40-70 sekundi/konstatan učin 20). To prepare the membranes, cells were adjusted to a concentration of 108 cells/ml buffer (50 ml tris HCl buffer, pH 7.4) and then disintegrated by ultrasound (Branson Sonifier 250, 40-70 seconds/constant power 20).
Ispitivanja vezanja Binding tests
Za ispitivanje vezanja ETA- i ETB-receptora membrane su suspendirane u puferu za inkubaciju (50 mM tris HCl, pH 7,4 s 5 mM MnCl2, 40 μg/ml bacitracina i 0,2% BSA) u koncentraciji od 50 μg proteina po ispitnoj smjesi i inkubiraju se pri 25oC s 25 pM 125J-ET1 (ispitivanje ETA-receptora) ili 25 pM 125J-ET3 (ispitivanje ETB-receptora) u prisutnosti ili odsutnosti ispitne tvari. Nespecifično vezanje određeno je s 10-7 M ET1. Nakon 30 minuta slobodan i vezani radioligand su rastavljeni filtriranjem kroz filtere od staklenih vlakana GF/B (Whatman, Engleska) na skupljaču stanica Skatron (Skatron, Lier, Norveška) i filteri su isprani s ledeno hladnim puferom tris HCl, pH 7,4 s 0,2% BSA. Radioaktivnost skupljena na filterima kvantitativno je utvrđena pomoću scintilacijskog brojača za tekućine Packard 2200 CA. To test the binding of ETA- and ETB-receptors, membranes were suspended in incubation buffer (50 mM Tris HCl, pH 7.4 with 5 mM MnCl2, 40 μg/ml bacitracin and 0.2% BSA) at a concentration of 50 μg protein per test mixture and are incubated at 25oC with 25 pM 125J-ET1 (ETA-receptor assay) or 25 pM 125J-ET3 (ETB-receptor assay) in the presence or absence of the test substance. Nonspecific binding was determined with 10-7 M ET1. After 30 min, free and bound radioligand were separated by filtration through GF/B glass fiber filters (Whatman, England) on a Skatron cell harvester (Skatron, Lier, Norway) and the filters were washed with ice-cold Tris HCl buffer, pH 7.4 for s 0.2% BSA. Radioactivity collected on the filters was quantified using a Packard 2200 CA liquid scintillation counter.
Ispitivanje ET-antagonista in vivo Testing of ET-antagonists in vivo
Mužjaci SD štakora, težine 250 - 300 g, anestezirani su s amobarbitalom, priključeni na umjetno disanje, vagotomizirani i despinalizirani. Arteria carotis i vena jugularis bile su katetezirane. Male SD rats, weighing 250-300 g, were anesthetized with amobarbital, connected to artificial respiration, vagotomized and de-spinalized. The carotid artery and jugular vein were catheterized.
U skupini kontrolnih životinja intravensko davanje 1 μg/kg ET1 dovelo je do jasnog porasta krvnog tlaka, koji se je održao tijekom relativno duljeg vremena. In the group of control animals, intravenous administration of 1 μg/kg ET1 led to a clear increase in blood pressure, which was maintained for a relatively long time.
Pokusnim životinjama, 30 minuta prije davanja ET1, ubrizgani su ispitni spojevi i.v. (1 mg/kg). Za određivanje ET-antagonističkih svojstava porast krvnog tlaka pokusnih životinja bio je uspoređen s onim kod kontrolnih životinja. Experimental animals, 30 minutes before the administration of ET1, were injected with the test compounds i.v. (1 mg/kg). To determine the ET-antagonistic properties, the increase in blood pressure of experimental animals was compared with that of control animals.
Oralno ispitivanje miješanih ETA- i ETB-antagonista Oral testing of mixed ETA- and ETB-antagonists
Mužjaci normotenzivnih štakora (Sprague Dawley, Janvier) težine 250-350 g najprije su oralno primili ispitne tvari. 80 minuta kasnije životinje su anestezirane s uretanom, a arteria carotis (za mjerenje krvnog tlaka) kao i vena jugularis (aplikacija big endotelin/endotelin 1) su kateterizirane. Male normotensive rats (Sprague Dawley, Janvier) weighing 250-350 g first received test substances orally. 80 minutes later the animals were anesthetized with urethane, and the carotid artery (for blood pressure measurement) as well as the jugular vein (big endothelin/endothelin 1 application) were catheterized.
Nakon faze stabilizacije, intravenski je dat big endotelin (20 μg/kg, aplicirani volumen 0,5 ml/kg), odnosno ET1 (0,3 μg/kg, aplicirani volumen 0,5 ml/kg). Krvni tlak i srčana frekvencija registrirani su kontinuirano tijekom 30 minuta. Jasne i trajne promjene krvnog tlaka računate su kao površine ispod krivulje (AUC). Za određivanje antagonističkog djelovanja ispitnih tvari AUC životinja koje su primile ispitne tvari uspoređen je s AUC-om kontrolnih životinja. After the stabilization phase, big endothelin (20 μg/kg, applied volume 0.5 ml/kg) or ET1 (0.3 μg/kg, applied volume 0.5 ml/kg) was given intravenously. Blood pressure and heart rate were registered continuously for 30 minutes. Clear and persistent changes in blood pressure were calculated as area under the curve (AUC). To determine the antagonistic effect of the test substances, the AUC of the animals that received the test substances was compared with the AUC of the control animals.
