Patent Application
20150080438
The invention relates to selective oestrogen receptor modulators (SERMs) and to processes for their preparation, to their use for the treatment and/or prophylaxis of diseases and to their use for preparing medicaments for the treatment and/or prophylaxis of diseases, in particular of bleeding disorders, osteoporosis, endometriosis, myomata, hormone-dependent tumours, for hormone replacement therapy and for contraception.
SERMs are compounds that have, tissue-selectively, either an anti-oestrogenic/oestrogen-inhibiting or an oestrogenic or partially oestrogenic action, for example in the case of the uterus they inhibit the action of oestrogen, but in the case of bone they have a neutral or oestrogen-like action. Tamoxifen, raloxifene and bazedoxifene may be mentioned as examples of such compounds. SERMs are to be differentiated from pure anti-oestrogens, which have a purely antagonistic action, inhibiting the action of oestrogen, in all tissues and do not display any oestrogenic or partially oestrogenic action in a tissue. SERDs (selective oestrogen receptor downregulators) belong to the anti-oestrogens and lead at the protein level to complete degradation of the oestrogen receptor in the target cells. The compound fulvestrant may be mentioned as an example of a pure anti-oestrogen or SERD.
6,7-Dihydro-5H-benzo[7]annulene derivatives as SERMs and their use in the treatment of bleeding disorders, osteoporosis, endometriosis, myomata, hormone-dependent tumours, for hormone replacement therapy and for contraception have been already described (cf. WO 00/03979).

It is an object of the present invention to provide alternative substances acting as SERMs with improved physicochemical properties.
The present invention provides compounds of the formula (I)
in which
It was found that 6,7-dihydro-5H-benzo[7]annulene derivatives (I) which have a substituted aromatic substituent as described above attached at the 8-position and which have an optionally substituted aliphatic chain attached in position 9 act as SERMs. Many of the claimed 6,7-dihydro-5H-benzo[7]annulene derivatives have a destabilizing effect on the ERα content (remaining relative ERα content less than or equal to 30%). Over the entire structural range, these compounds display a high anti-oestrogenic action in vitro (IC50 values below 0.3 micromolar) and predominantly even double-digit or single-digit nanomolar IC50 values for the inhibition of estradiol-induced luciferase activity.

Gestagens are understood in the sense of the present invention either as natural progesterone itself or synthetic (steroidal and non-steroidal) derivatives, which like progesterone itself bind to the progesterone receptor and, in dosages that are above the ovulation inhibiting dose, inhibit ovulation. The following may be mentioned as examples of gestagens: levonorgestrel, norgestimate, norethisterone, dydrogesterone, drospirenone, 3β-hydroxydesogestrel, 3-ketodesogestrel (=etonogestrel), 17-deacetylnorgestimate, 19-norprogesterone, acetoxypregnenolone, allylestrenol, amgestone, chloromadinone, cyproterone, demegestone, desogestrel, dienogest, dihydrogesterone, dimethisterone, ethisterone, ethynodiol diacetate, flurogestone acetate, gestrinone, gestodene, gestrinone, hydroxymethylprogesterone, hydroxyprogesterone, lynestrenol (=lynoestrenol), mecirogestone, medroxyprogesterone, megestrol, melengestrol, nomegestrol, norethindrone (=norethisterone), norethynodrel, norgestrel (including d-norgestrel and dl-norgestrel), norgestrienone, normethisterone, progesterone, quingestanol, (17α)-17-hydroxy-11-methylene-19-norpregna-4,15-dien-20-yn-3-one, tibolone, trimegestone, algestone acetophenide, nestorone, promegestone, 17-hydroxyprogesterone ester, 19-nor-17-hydroxyprogesterone, 17α-ethynyl-testosterone, 17α-ethynyl-19-nortestosterone, d-17β-acetoxy-13β-ethyl-17α-ethynyl-gon-4-en-3-one oxime or the compounds disclosed in WO 00/66570, in particular tanaproget. Levonorgestrel, norgestimate, norethisterone, drospirenone, dydrogesterone and dienogest are preferred. Drospirenone and dienogest are especially preferred.
Progesterone receptor antagonists are compounds which inhibit the action of progesterone on its receptor. As examples we may mention RU 486, onapristone, lonaprisan (11β-(4-acetylphenyl)-17β-hydroxy-17α-(1,1,2,2,2-pentafluoroethyl)estra-4,9-dien-3-one cf. WO 98/34947) and the compounds claimed in WO 08/58767.
However, combinations with one or more further active compounds are also feasible, in particular combinations with aromatase inhibitors, 17beta HSD1 inhibitors, steroid sulphatase (STS) inhibitors, LHRH analogues, LHRH antagonists, GnRH agonists and antagonists, kisspeptin receptor (KISSR) antagonists, selective androgen receptor modulators (SARMs), androgens, selective progesterone receptor modulators (SPRMs), gestagens, antigestagens (progesterone receptor antagonists), oral contraceptives, oestrogens, inhibitors of mitogen activated protein (MAP) kinases and inhibitors of MAP kinases kinases (Mkk3/6, Mek1/2, Erk1/2) inhibitors of protein kinases B (PKBα/β/γ; Akt1/2/3), inhibitors of phosphoinositide 3-kinases (PI3K), inhibitors of cyclin-dependent kinase (CDK1/2), inhibitors of the hypoxia-induced signal pathway (HIF1alpha inhibitors, activators of prolyl hydroxylases), histone deacetylase (HDAC) inhibitors, prostaglandin F receptor (FP) (PTGFR) antagonists and non-steroidal antiinflammatory drugs (NSAIDs) for the treatment of endometriosis.
The invention also relates to pharmaceutical preparations comprising at least one compound of general formula I (or physiologically acceptable addition salt thereof with organic and inorganic acids) and to the use of these compounds for the preparation of medicaments, in particular for the indications mentioned above.
The compounds can be used for the indications mentioned above, both by oral and parenteral administration.
The compounds can also be used in combination with the natural vitamin D3 or with calcitriol analogues for osteogenesis or as supporting therapy for therapies that cause loss of bone mass (for example therapy with glucocorticoids, chemotherapy).
The compounds of general formula I can also be used in combination with progesterone receptor antagonists or in combination with pure oestrogens, and in particular for use in hormone replacement therapy and for the treatment of gynaecological disorders and for controlling female fertility. A therapeutic product, comprising an oestrogen and a pure anti-oestrogen for simultaneous, sequential or separate use for selective oestrogen therapy of perimenopausal or postmenopausal states has already been described in EP-A 0 346 014.
The compounds of general formula I can also be given in combination with gestagens and substances with gestagenic action, in particular for use in premenopausal women for the treatment of gynaecological diseases such as endometriosis, myomata or disturbances of menstruation e.g. dysmenorrhoea or hypermenorrhoea, or for the treatment of hormone-dependent tumours, e.g. breast cancer.
The compounds of general formula I can be administered either continuously (for example once daily) or in intermittent regimens. Treatment regimes such as once weekly, once monthly, daily for a period of several days, on particular days of the female menstrual cycle (e.g. on 14 consecutive days of the secretory phase or several days in the middle of the menstrual cycle) may be mentioned by way of example (but not exclusively). The compounds of general formula I can also be administered continuously over a longer treatment period (e.g. 14-168 successive days) followed by a treatment pause, which is either fixed (e.g. 14-84 days) or is flexible and lasts until the next menstruation. In these intermittent treatment regimens the compounds of general formula I can be administered alone or in combination with the combination therapies mentioned above, and these for their part can be administered continuously or also intermittently.
The compounds according to the invention can have systemic and/or local action. For this purpose, they can be administered in a suitable way, for example orally, parenterally, pulmonarily, nasally, sublingually, lingually, buccally, rectally, dermally, transdermally, conjunctivally, otically or as an implant or stent.
For these routes of application, the compounds according to the invention can be administered in suitable dosage forms.
Dosage forms that function according to the prior art, with rapid and/or modified release of the compounds according to the invention, containing the compounds according to the invention in crystalline and/or amorphisized and/or dissolved form, are suitable for oral administration, for example tablets (uncoated or coated tablets, for example with enteric coatings or coatings with delayed dissolution or insoluble coatings, which control the release of the compound according to the invention), tablets that disintegrate rapidly in the oral cavity or films/wafers, films/lyophilisates, capsules (for example hard-gelatin or soft-gelatin capsules), sugar-coated tablets, granules, pellets, powders, emulsions, suspensions, aerosols or solutions.
Parenteral administration can take place with avoidance of an absorption step (for example intravenously, intra-arterially, intracardially, intraspinally or intralumbally) or with inclusion of absorption (for example intramuscularly, subcutaneously, intracutaneously, percutaneously or intraperitoneally). Suitable dosage forms for parenteral administration are inter alia injection and infusion preparations in the form of solutions, suspensions, emulsions, lyophilisates or sterile powders.
Suitable dosage forms for the other routes of administration are, for example, pharmaceutical forms for inhalation (inter alia powder inhalers, nebulizers), nasal drops, solutions, and sprays; tablets for lingual, sublingual or buccal administration, films/wafers or capsules, suppositories, ear or eye preparations, vaginal capsules, aqueous suspensions (lotions, shaking mixtures), lipophilic suspensions, ointments, creams, transdermal therapeutic systems (such as, for example, patches), milk, pastes, foams, dusting powders, implants, intrauterine systems, vaginal rings or stents.
The compounds according to the invention can be converted into the stated dosage forms. This can take place in a manner that is known per se, by mixing with inert, non-toxic, pharmaceutically suitable auxiliaries. These auxiliaries include inter alia vehicles (for example microcrystalline cellulose, lactose, mannitol), solvents (for example liquid polyethylene glycols), emulsifiers and dispersants or wetting agents (for example sodium dodecylsulphate, polyoxysorbitan oleate), binders (for example polyvinylpyrrolidone), synthetic and natural polymers (for example albumin), stabilizers (for example antioxidants such as, for example, ascorbic acid), colorants (for example inorganic pigments such as, for example, iron oxides) and taste and/or odour correctants.
The present invention further relates to medicinal products comprising at least one compound according to the invention, usually together with one or more inert, non-toxic, pharmaceutically suitable auxiliaries, and their use for the purposes stated above.
In the case of oral administration, the amount per day is from about 0.01 to 100 mg/kg of body weight. The amount of a compound of the general formula I to be administered varies over a wide range and can cover every effective amount. Depending on the condition to be treated and the method of administration, the amount of the compound administered can be 0.01-100 mg/kg of body weight per day.
Nevertheless, it may optionally be necessary to deviate from the stated amounts, mainly depending on body weight, route of administration, individual response to the active substance, type of preparation and time point or interval in which administration takes place. Thus, in some cases it may be sufficient to use less than the aforementioned minimum amount, whereas in other cases the stated upper limit must be exceeded. In the case of administration of relatively large amounts, it may be advisable to divide these into several individual doses throughout the day.
The percentages in the following tests and examples are, unless stated otherwise, percentages by weight; parts are parts by weight. Proportions of solvents, dilution ratios and information about concentration for liquid/liquid solutions relate in each case to volume.

In addition to inhibition of the transcriptional activity of the ER, anti-oestrogens influence the expression level of the ER in the target tissues through stimulation of the proteolytic degradation of the ER. In comparison with an ER-E2 complex, the ER bound in a complex with the pure anti-oestrogen fulvestrant has a substantially shorter half-life. Conversely, the ER stability is enhanced by the SERM tamoxifen, so that overall there is ER stabilization. All things considered, it can be assumed that the capacity of pure anti-oestrogens and certain SERMs for inducing ER degradation contributes significantly to the overall action of the compounds. Compounds that have a destabilizing property, but at the same time display the desired tissue-specific agonistic qualities, e.g. bone protection, should on the whole present a superior pharmacological profile, as they have a lower potential for side effects, such as stimulation of the endometrium.
The effect of the claimed pharmacological compounds on the stability of the ER was analysed in T47D breast cancer cells (see Table 1, column Standardized ER-destabilization [%]). These cells express the ER in functional form. The cells are incubated for 24 hours with the claimed compounds at a concentration of 1 μM. After lysis of the cells, the content of ER protein was determined by ELISA. Treatment with the complete destabilizer fulvestrant (0% ER), the stabilizer tamoxifen (100% ER) and the control medium (approx. 30% ER) was used as comparison. Compounds having an ER content below 30% are classified as destabilizing.
As described, the claimed pharmacological substances were investigated for their action on the stability of the ERα protein (see Table 1). Over most of the claimed structural range, the pharmacological substances display a destabilizing action on the ERα content (remaining relative ERα content of less than or equal to 30%).
The anti-oestrogenic action of the claimed pharmacological compounds was investigated in so-called MVLN cells in vitro. MVLN cells are derivatives of the hormone-responsive MCF7 breast cancer cells known by a person skilled in the art. These MVLN cells express, along with the functional oestrogen receptor (ER), a reporter construct, which under ER-activation expresses luciferase. Determination of the activity of the induced luciferase permits a direct conclusion on the oestrogen properties of substances. To investigate the anti-oestrogenic properties of the pharmacological compounds, they were investigated in the presence of oestrogen for their potential for inhibiting the luciferase signal induced by estradiol.
The claimed pharmacological test substances were investigated in MVLN cells for their anti-oestrogenic potential, as described (see Table 2). Over the entire structural range, these compounds show high potency (IC50 values below 0.3 μM) and primarily even double-digit or single-digit nanomolar IC50 values for the inhibition of estradiol-induced luciferase activity.
The suitability of the compounds according to the invention for the treatment of endometriosis can be demonstrated in the following animal models. The influence of the compounds according to the invention on the uterus was investigated in the uterus growth test (oestrogenic action) and in the anti-uterus growth test (anti-oestrogenic action), both conducted in rats.
The uterus of oestrogen-substituted rats can be used as a test model for detecting a direct action of substances with anti-oestrogenic properties. The parameter of oestrogenic action is estradiol-induced uterus growth in rats, which is inhibited by simultaneous administration of a substance with anti-oestrogenic action.
The experimental animals (n=5-6 animals/group) were ovariectomized before the start of the test, to rule out the influence of endogenous oestrogens. After a phase of 6 to 10 days, the test substances are administered s.c. on 3 consecutive days (d1-d3) in combination with a substitution dose of 1.5 μg/kg/day of 17β-estradiol. 17β-estradiol alone serves as positive control, and the excipients serve as negative control. On day 4 (d4) the animals are killed, and the uteri and vaginae are removed and weighed. The organ weights are converted to mg/100 g body weight, then the mean value and the standard deviation are calculated for each dosage. The inhibition of uterus or vaginal growth induced by 17β-estradiol is shown as percentage inhibition.
The compounds according to the invention largely show very pronounced inhibition of uterus growth induced by 17β-estradiol.
The compounds according to the invention are therefore superior in the sense of the present invention, with respect to their action on the uterus, to the compounds of the prior art, in that they have less, if any, oestrogenic action on this organ.
The selected claimed substances were investigated in adult female rats as described for their anti-oestrogenic, inhibitory action on the weight of the uterus. At the dosage used, the substances show a marked anti-oestrogenic action in vivo (Table 3 and Table 4).
The clinical use both of pure anti-oestrogens and of various SERMs for the treatment of premenopausal women is limited by their property of stimulating the ovaries through activation of the hypothalamic-pituitary-gonadal axis (HPG axis), which leads to the increase in peripheral estradiol levels (Palomba, S., Orio, F., Jr., Morelli, M., Russo, T., Pellicano, M., Zupi, E., Lombardi, G., Nappi, C., Panici, P. L., and Zullo, F. (2002). Raloxifene administration in premenopausal women with uterine leiomyomas: a pilot study. J Clin Endocrinol Metab 87, 3603-3608). This stimulation of the HPG axis is associated with penetration of the blood-brain barrier and penetration of the brain. To investigate the ovary-stimulating properties of the claimed pharmacological compounds, hormonally intact adult rats were treated with the substances daily for a period of 10 days. The study end point is the quotient of peripheral estradiol values after and before treatment.
In comparison with pure anti-oestrogens and the classical SERMs such as raloxifene or bazedoxifene, the selected claimed pharmacological compounds show markedly less stimulation of the HPG axis at equal dosage. They therefore display superior properties for clinical use in premenopausal women.
Selected claimed pharmacological substances were investigated as described for their stimulating action on the HPG axis or ovarian estradiol synthesis. The selected substances show markedly less stimulation of the ovaries than the control compound raloxifene at equal dosages (cf. Table 5).
Determination of bioavailability after intragastric application of test substances was carried out in conscious female rats with a body weight from at least 0.2 kg to at most 0.25 kg. For this, the test substances were applied in dissolved form both for intravenous and for intragastric application, where compatible solubilizers such as PEG400 and/or ethanol were used in a compatible amount.
a) Intravenous Administration:
The test substances were administered at a dose of 0.5-1 mg/kg as quick infusion over a period of 15 minutes. At the time points 2 min, 8 min, 15 min (infusion) and 5 min, 15 min, 30 min, 45 min, 1 h, 2 h, 4 h, 6 h, 8 h, 12 h, 16 h, 20 h, 24 h after the end of infusion, about 150 μl blood samples were taken via a catheter from the jugular vein. Lithium-heparin was added as anticoagulant to the blood samples and they were stored in a refrigerator until required for further processing. After centrifugation of the samples at 3000 rpm for 15 min, an aliquot of 100 μl was taken from the supernatant (plasma) and was precipitated by adding 400 μl of cold acetonitrile or methanol (absolute). The precipitated samples were frozen-out overnight at −20° C., then centrifuged once again for 15 min at 3000 rpm, before taking 150 μl of the clear supernatant for determination of concentration. Analysis used an Agilent 1200 HPLC system coupled to LCMS/MS detection.

Lithium-heparin was added as anticoagulant to the blood samples and they were stored in a refrigerator until required for further processing. After centrifuging the samples for 15 min at 3000 rpm, an aliquot of 100 μl was taken from the supernatant (plasma) and was precipitated by adding 400 μl of cold acetonitrile or methanol (absolute). The precipitated samples were frozen-out overnight at −20° C., then centrifuged for 15 min at 3000 rpm before 150 μl of the clear supernatant was drawn off for determination of concentration. Analysis was carried out using an Agilent 1200 HPLC system coupled to LCMS/MS detection.
