Description
Ovaj izum se odnosi na supstituirane derivate karbazola, na postupke njihovog dobivanja, na farmaceutske pripravke koji ih sadrže kao i na njihovu uporabu u medicini za smanjenje nivoa estrogena i/ili androgena. Aktivnost 17,20-liaze je odgovorna za konverziju 17α-hidroksiprogesterona do androstenediona i 17α-hidroksipregnenolona do dehidroepiandrosterona. Ova aktivnost je kritična za biosintezu androgena, te inhibicija 17,20-liaze pomoću ketakonazola (poznatog antimikotičkog sredstva) pokazuje smanjenje nivoa testosterona kod životinja (English, H. F. i sur., Cancer Res. 47, 38-42 (1986) i ljudi (Pont, A. i sur., Arch. Intern. Med. 142, 2137-2140 (1982). This invention relates to substituted carbazole derivatives, to their production processes, to pharmaceutical preparations containing them, as well as to their use in medicine to reduce estrogen and/or androgen levels. 17,20-lyase activity is responsible for the conversion of 17α-hydroxyprogesterone to androstenedione and 17α-hydroxypregnenolone to dehydroepiandrosterone. This activity is critical for androgen biosynthesis, and inhibition of 17,20-lyase by ketaconazole (a known antimycotic agent) has been shown to decrease testosterone levels in animals (English, H.F. et al., Cancer Res. 47, 38-42 (1986)) and humans ( Pont, A. et al., Arch. Intern. Med. 142, 2137-2140 (1982).
U liječenju karcinoma prostate su korištene velike doze ketakonazola (Trachtenberg, J., J. Urol. 61-63 (1984) i Pont, A. i sur., Arch. Intern. Med. 145, 1429-1431 (1985)). Naravno, doze ketakonazola koje izazivaju inhibiciju produkcije testosterona su znatno toksičnije od antimikotičnih doza, a za selektivnije 17,20-liaza inhibitore se očekuje da imaju znatno bolji terapeutski indeks. Large doses of ketaconazole have been used in the treatment of prostate cancer (Trachtenberg, J., J. Urol. 61-63 (1984) and Pont, A. et al., Arch. Intern. Med. 145, 1429-1431 (1985)). Of course, doses of ketaconazole that cause inhibition of testosterone production are significantly more toxic than antimycotic doses, and more selective 17,20-lyase inhibitors are expected to have a significantly better therapeutic index.
Inhibicija 17,20-liaze, kao pristup inhibiciji biosinteza testosterona, ima prednost također i u tome da blokira adrenalno kao i testikularno dobivene androgene (English, H. F. i sur., Cancer Res. 46, 38-42 (1986)), te je za očekivati da će biti znatno učinkovitija u liječenju karcinoma prostate od LHRH agonista. Inhibition of 17,20-lyase, as an approach to inhibiting testosterone biosynthesis, also has the advantage of blocking adrenal as well as testicular derived androgens (English, H.F. et al., Cancer Res. 46, 38-42 (1986)), and is expect that it will be significantly more effective in the treatment of prostate cancer than LHRH agonists.

U idućem općem postupku (C) spoj formule (I) prema izumu može se prevesti u neki drugi spoj prema izumu In the following general procedure (C), the compound of formula (I) according to the invention can be converted into another compound according to the invention
upotrebom uobičajenih postupaka. using usual procedures.
Prema jednom obliku općeg postupka (C), spoj formule (I) u kojoj R1 predstavlja atom vodika, se može alkilirati upotrebom uobičajene tehnike. Reakcija se može provesti upotrebom prikladnog alkilirajućeg sredstva poput alkil halida, alkil tosilata ili dialkilsulfata. Reakcija se uobičajeno može provesti u inertnom organskom otapalu poput amida, npr. dimetilformamida, ili etera, npr. tetrahidrofurana, povoljno je u prisutnosti lužine. Prikladne lužine uključuju, na primjer, hidride alkalijskih metala, npr. natrijev hidrid, karbonate alkalijskih metala, npr. natrijev karbonat, ili alkokside alkalijskih metala, npr. natrijev ili kalijev metoksid, etoksid ili t-butoksid. Reakcija alkiliranja se uobičajeno provodi pri temperaturi 25 do 100°C. According to one form of the general process (C), the compound of formula (I) in which R1 represents a hydrogen atom, can be alkylated using a conventional technique. The reaction can be carried out using a suitable alkylating agent such as an alkyl halide, alkyl tosylate or dialkyl sulfate. The reaction can usually be carried out in an inert organic solvent such as an amide, eg dimethylformamide, or an ether, eg tetrahydrofuran, preferably in the presence of an alkali. Suitable bases include, for example, alkali metal hydrides, eg sodium hydride, alkali metal carbonates, eg sodium carbonate, or alkali metal alkoxides, eg sodium or potassium methoxide, ethoxide or t-butoxide. The alkylation reaction is usually carried out at a temperature of 25 to 100°C.
Prema idućem općem postupku (D), spoj formule (I) prema izumu, ili njegova sol se mogu pripremiti podvrgavanjem zaštićenog derivata formule (I) ili njegove soli, reakciji da bi se uklonila zaštitna grupa ili grupe. Tako, u ranijem koraku tokom pripreme spoja formule (I) ili njegove soli, može biti neophodno i/ili poželjno da se zaštiti jedna ili više osjetljivih grupa u molekuli da bi se spriječile nepoželjne nuz reakcije. Takova zaštita se može provesti na uobičajen način, na primjer kako je to opisano u "Protective Groups in Organic Chemistry" Ed.J.F.W.McOmie (Plenum Press 1973) ili u "Protective Groups in Organic Synthesis" od TW Greene (John Wiley and Sons 1981). According to the following general procedure (D), a compound of formula (I) according to the invention, or a salt thereof, can be prepared by subjecting a protected derivative of formula (I) or a salt thereof, to a reaction to remove the protecting group or groups. Thus, in an earlier step during the preparation of a compound of formula (I) or a salt thereof, it may be necessary and/or desirable to protect one or more sensitive groups in the molecule to prevent undesirable side reactions. Such protection can be carried out in a conventional manner, for example as described in "Protective Groups in Organic Chemistry" by Ed.J.F.W.McOmie (Plenum Press 1973) or in "Protective Groups in Organic Synthesis" by TW Greene (John Wiley and Sons 1981 ).
U spojevima formule (I) u kojima R1 predstavlja vodik, grupa NR1 može biti zaštićena na primjer sa uobičajenom amino zaštitnom grupom. Takove grupe mogu uklučivati na primjer aralkil grupe, poput benzil, difenilmetil ili trifenilmetil grupa; te acil grupe poput tosil, N-benziloksikarbonil ili t-butoksikarbonil. In compounds of formula (I) in which R1 represents hydrogen, the group NR1 can be protected, for example, with a conventional amino protecting group. Such groups may include, for example, aralkyl groups, such as benzyl, diphenylmethyl or triphenylmethyl groups; and acyl groups such as tosyl, N-benzyloxycarbonyl or t-butoxycarbonyl.
Uklanjanje bilo koje prikazane zaštitne grupe se može postići uobičajenim postupcima. Tako se, aralkil grupe poput benzil grupe, mogu odcijepiti hidrogenolizom u prisutnosti katalizatora (npr. paladij na drvenom ugljenu); acil grupa poput t-butoksikarbonil grupe se može ukloniti cijepanjem sa, na primjer, klorovodikom u dioksanu ili sa natrijevim metoksidom u metanolu. Removal of any protecting group shown can be accomplished by conventional procedures. Thus, aralkyl groups such as benzyl groups can be cleaved by hydrogenolysis in the presence of a catalyst (eg palladium on charcoal); an acyl group such as a t-butoxycarbonyl group can be removed by cleavage with, for example, hydrogen chloride in dioxane or sodium methoxide in methanol.
Razumljivo je da će u nekim slučajevima ranije opisanih općih postupaka (A) do (C), biti neophodno ili poželjno da se zaštiti bilo koja osjetljiva grupa na upravo opisan način. Tako, reakcijski korak koji obuhvaća deprotekciju zaštićenog derivata opće formule (I) ili njegove soli se može provesti neposredno nakon bilo kojeg od opisanih postupaka (A) do (C). It is understood that in some cases of the previously described general procedures (A) to (C), it will be necessary or desirable to protect any vulnerable group in the manner just described. Thus, the reaction step comprising the deprotection of the protected derivative of the general formula (I) or its salt can be carried out directly after any of the described processes (A) to (C).
Tamo gdje je poželjno da se spoj prema izumu izolira kao sol, na primjer kao kiselinska sol, to se može postići tretiranjem slobodne baze opće formule (I) sa odgovarajućom kiselinom, povoljno je sa ekvivalentim iznosom. Solvati spojeva prema izumu se mogu pripremiti kristalizacijom iz ili evaporacijom odgovarajućeg otapala iz otopine spoja formule (I). Separacija enantiomera formule (I) se može provesti na uobičajen način, na primjer re-otapanjem racemičnih smjesa npr. upotrebom kiralne HPLC tehnike ili pomoću stereospecifične sinteze iz izomerično čistih polaznih materijala ili intermedijera, na primjer kako je to opisano u Stereochemistry of Carbon Compounds od E. L. Eliel (McGraw Hill, 1962) i u Tables of Resolving Agents od S.H.Wilen. Where it is desirable to isolate a compound of the invention as a salt, for example as an acid salt, this can be achieved by treating the free base of general formula (I) with an appropriate acid, preferably an equivalent amount. Solvates of the compounds according to the invention can be prepared by crystallization from or evaporation of a suitable solvent from a solution of the compound of formula (I). Separation of the enantiomers of formula (I) can be carried out in a conventional way, for example by re-dissolving racemic mixtures, for example using a chiral HPLC technique or by stereospecific synthesis from isomerically pure starting materials or intermediates, for example as described in Stereochemistry of Carbon Compounds by E. L. Eliel (McGraw Hill, 1962) and in Tables of Resolving Agents by S. H. Wilen.
Tako, prema idućem aspektu izuma, slijedeće reakcije se mogu, ako je to neophodno i/ili poželjno provesti bilo kojim odgovarajućim redoslijedom neposredno nakon bilo kojeg od postupaka (A) do (C): Thus, according to a further aspect of the invention, the following reactions can, if necessary and/or desirable, be carried out in any suitable order immediately after any of the processes (A) to (C):
(i) uklanjanje bilo koje zaštitne grupe; (i) removal of any protecting group;
(ii) konverzija spoja formule (I) ili njegove soli ili solvata u njegovu farmaceutski prihvatljivu sol ili solvat (na primjer, hidrat); (ii) converting a compound of formula (I) or a salt or solvate thereof into a pharmaceutically acceptable salt or solvate thereof (for example, a hydrate);
(iii) odijeljivanje racemične smjese u pojedinačne enantiomere formule (I). (iii) separation of the racemic mixture into individual enantiomers of formula (I).
Osim što se mogu koristiti kao posljednji glavni korak u pripremi, ranije navedeni opći postupci za pripremu spojeva prema izumu, mogu se koristiti i za uvođenje željenih grupa u bilo kojem intermedijernom stadiju u toku pripreme željenog spoja. Zbog toga, treba biti razumljivo da u takvom višestepenom postupku, redoslijed reakcija treba izabrati tako da reakcijski uvjeti ne utječu na grupe prisutne u molekuli, koje se žele zadržati u konačnom produktu. In addition to being used as the last major step in the preparation, the previously mentioned general procedures for the preparation of the compounds according to the invention can also be used to introduce the desired groups at any intermediate stage during the preparation of the desired compound. Therefore, it should be understood that in such a multi-step procedure, the order of the reactions should be chosen so that the reaction conditions do not affect the groups present in the molecule, which want to be retained in the final product.
Kao što je to ranije navedeno, spojevi prema izumu su korisni 17,20-liaza inhibitori. 17,20-iaza inhibicija se može prikazati slijedećim testovima: As noted earlier, the compounds of the invention are useful 17,20-lyase inhibitors. 17,20-Iase inhibition can be demonstrated by the following tests:
Aktivnost in vitro Activity in vitro
Biološka aktivnost in vitro je određena mjerenjem inhibicije 17,20-liaza aktivnosti u mikrosomalnom preparatu dobivenom iz humanih testisa. Raspon koncentracija svakog spoja je inkubiran sa mikrosomalnim preparatom i 17-α-hidroksi (21-14C) pregnenolonom kao supstratom tokom 60 minuta na 37°C. Ispita se radioaktivni produkt i inhibicija se odredi usporedbom sa neinhibiranim kontrolnim uzorcima. Biological activity in vitro was determined by measuring the inhibition of 17,20-lyase activity in a microsomal preparation obtained from human testes. A range of concentrations of each compound was incubated with the microsomal preparation and 17-α-hydroxy (21-14C) pregnenolone as a substrate for 60 minutes at 37°C. The radioactive product is tested and inhibition is determined by comparison with non-inhibited control samples.
Aktivnost in vivo Activity in vivo
Biološka aktivnost in vivo je određena na modelu biosinteze testosterona kod štakora. Spojevi su primjenjeni p.o. u dozi 3mg/kg. Jedan sat kasnije štakorima je dano s.c. humani korionski gonadotropin (hCG) da bi se stimulirala sinteza testosterona te je dva sata nakon primjene hCG uzeta krv i mjerene su koncentracije testosterona u serumu. Inhibicijska aktivnost je određena usporedbom sa vrijednostima dobivenim za štakore koji su primili isključivo vehikulum. Biological activity in vivo was determined on the model of testosterone biosynthesis in rats. Compounds were administered p.o. in a dose of 3 mg/kg. One hour later, rats were given s.c. human chorionic gonadotropin (hCG) to stimulate testosterone synthesis, and two hours after hCG administration blood was taken and serum testosterone concentrations were measured. Inhibitory activity was determined by comparison with values obtained for rats that received vehicle alone.

The results of the in vivo and in vitro assays for the compounds of the following examples are shown in Table 1. The results for the known 17,20-lyase inhibitor ketoconazole are included for comparison.
