Background Art Documents and other materials used herein to clarify the background of the invention and to provide additional details, particularly relating to implementation, are disclosed by reference.

  Mammalian 17β-hydroxysteroid dehydrogenases (17β-HSDs) are NAD (H) or NADP (H) dependent enzymes that convert inactive 17-ketosteroids into their active 17β-hydroxy forms. Or catalyzes the oxidation of the 17β-hydroxy form to a 17-ketosteroid. Since both esterogens and androgens have the highest affinity in their 17β-hydroxy form for their receptors, the 17β-HSD enzyme plays an essential role in the tissue-selective control of the activity of sex steroid hormones. Currently, 10 human 17β-HSD enzyme family members have been described (types 1-5, 7, 8, 10-12), where each type of 17β-HSD is a selective substrate. Has affinity, directed (reductive or oxidative) activity in intact cells, and specific tissue distribution.

  Due to their essential role in the tissue-selective control of their sex steroid hormone activity, 17β-HDSs have estrogen-sensitive pathologies (eg breast cancer, ovarian cancer and endometrial cancer) and androgen-sensitive pathologies (eg prostate Cancer, benign prostatic hypertrophy, acne, hirsutism, etc.). In addition, many types of 17β-HSD are involved in the pathogenesis of certain human diseases such as pseudohemiyang (17β-HSD3), renal cysts (17β-HSD8) and biceps enzyme deficiency (17β-HSD4). [Review by Mindnich et al. (2004)]. Therefore, treatment of sex steroid-sensitive diseases by administration of specific inhibitors of 17β-HSDs has been proposed [Labrie et al. (1997)], possibly in combination with potent and specific antiestrogens and antiandrogens.

  The most characterized member of the 17β-HSD family is 17β-HSD1 [EC1.1.1.62]. The 17β-HSD1 enzyme catalyzes the reduction and oxidation between estrone (E1) and estradiol (E2) in vitro. However, under physiological in vivo conditions, the enzyme catalyzes only a reductive reaction from estrone (E1) to estradiol (E2). It has been found that 17β-HSD1 is expressed in various hormone-dependent tissues such as placenta, mammary tissue or uterine tissue and endometrial tissue.

  Estradiol itself is a very powerful hormone, especially in comparison to the less active estrone, which regulates the expression of various genes by binding to nuclear estrogen receptors and the target cell It plays an essential role in proliferation and differentiation. Physiological as well as pathological cell growth may be estradiol dependent. In particular, many breast cancer cells are stimulated by locally elevated estradiol concentrations. Furthermore, the occurrence or course of benign pathologies such as endometriosis, uterine fibroids (fibromas or fibroids), adenomyosis, menorrhagia, uterine bleeding and dysmenorrhea depends on the presence of fairly high estradiol levels. ing.

  Endometriosis is a well-known gynecological disease affecting 10-15% of women of childbearing age. Endometriosis is an estrogen-dependent disease that does not occur before puberty and is rare after menopause. This is a benign disease defined as the presence of endometrial gland cells and stromal cells that can survive outside the uterine cavity. It is most often found in the pelvic area. For women who have developed endometriosis, endometrial cells that have entered the abdominal cavity by retrograde menstruation (the most likely mechanism) have the ability to adhere and invade the abdominal lining, then transplant and Can grow. The implant responds to the menstrual cycle steroid hormones as well as the endometrium in the uterus. Estrogen synthesis within the endometriotic lesion is increased as a result of the unusually high aromatase and local concentration of 17β-HSD1, which is accompanied by a decrease in the expression of 17βHSD2, an enzyme that inactivates estradiol. [Zei-toun et al. (1998)]. These higher local estrogen concentrations also induce the production of prostaglandin E2, which in turn stimulates further aromatase activity. Consequently, this vicious cycle causes additional estrogen production. Wetting lesions and blood from these lesions that cannot leave the body causes inflammation around the tissue. The most common symptoms of endometriosis are dysmenorrhea, sexual pain and (chronic) abdominal pain. To date, there is no reliable non-invasive test for diagnosing endometriosis. Laparoscopy must be performed to diagnose this disease. Endometriosis is classified according to four stages presented by the American Infertility Society (AFS). Depending on the location and extent of endometriosis, stage I corresponds to the mildest disease, while stage IV is severe. Endometriosis is found in up to 50% of infertile women. Moderate to severe endometriosis can cause tubal damage and adhesions, which can lead to infertility. The purpose of treatment of endometriosis is analgesia, resolution of endometrial tissue and (optionally) recovery of fertility. Two common treatments are surgery, or anti-inflammatory and / or hormonal therapy or a combination thereof.

  Uterine fibroids (fibromas or fibroids), benign clonal tumors arise from human uterine smooth muscle cells. They are found clinically in up to 25% of women and are the only most common indication for hysterectomy. They result in prolonged and severe menstrual bleeding, pelvic pressure, pain, urinary problems and, in rare cases, high relapse rates, including reproductive dysfunction. Myomas are found submucosally (sub-endometrial), in the wall (in the myometrium), and subserosa (protruding from the serosal segment of the uterus), but most of these three different types It is a mixed form. The presence of estrogen receptors in leiomyoma cells has been studied by Tamaya et al. [Yamaya et al. (1985)]. They demonstrated that the ratio of estrogen receptor compared to the level of progesterone receptor and androgen receptor is higher in myoma than in the corresponding normal myometrium. For a long time, surgery has been the main treatment for myomas. In addition, medical therapies proposed for the treatment of myomas include various steroids such as androgenic steroids, danazol or guestrinone and progestogens or compounds that modulate steroid hormone plasma concentrations such as GnRH agonists and GnRH antagonists. Wherein the administration is often associated with various severe side effects.

  Dysfunctional uterine bleeding disorders (dysfunctional or abnormal uterine bleeding, irregular uterine bleeding and menorrhagia, excessive menstruation), intrauterine organ changes (eg endometrial cancer, myoma, polyps, etc.), systemic It is a form of morbid bleeding that does not risk clotting disorders or pathological pregnancy (eg ectopic pregnancy, imminent miscarriage). The average blood loss during normal menstruation is about 30 ml, which averages 5 days. If the blood loss exceeds 80 ml, it is classified as pathological. Abnormal uterine bleeding is defined as bleeding that is painful or uninvolved and cannot be tied to menstruation or cycle. Menorrhagia is menstrual, whether painful or not, usually occurring every 27-28 days, which usually lasts more than 7 days and is often associated with increased blood loss. Menorrhagia is a syndrome of unknown origin, which is one of the most common problems in gynecology. Sixty percent of women who have been pointed to menorrhagia will have a hysterectomy within five years. Excessive menstruation is defined as menstruation that may or may not be painful with increased blood loss, usually every 27-28 days over 4-5 days. The form of dysfunctional uterine bleeding (mainly malformed uterine bleeding and menorrhagia) is typical in adolescence and menopause, with clustering of follicle irritation, anovulation, and luteal and follicular survival . The incidence of dysfunctional uterine bleeding is high, making it one of the most frequent reasons for gynecological examinations for women of reproductive age.

  Everything described above for the treatment of uterine fibroids, endometriosis and dysfunctional uterine bleeding is equally applicable to other benign gynecological diseases, especially adenomyosis and dysmenorrhea. These benign gynecological diseases are all estrogen sensitive and are treated as described above for uterine fibroids, endometriosis and dysfunctional uterine bleeding. However, the available medicinal treatments suffer from similar major drawbacks, i.e. their treatment needs to be interrupted if the side effects become more severe than the symptoms to be treated, It will reappear after the therapy interruption.

  Since the malignant and benign pathologies are all dependent on 17β-estradiol, a reduction in endogenous 17β-estradiol concentration in each tissue reduces the proliferation of 17β-estradiol responsive cells in the tissue. Or a reduction will be brought about. Thus, selective inhibitors of the 17β-HSD1 enzyme are very suitable for use for reducing endogenous production of estrogens, particularly 17β-estradiol, in myomas, endometrial tissues, adenomyoma tissues and endometrial tissues. You can conclude that Application of compounds that act as selective inhibitors for 17β-HSD1 that preferentially catalyze the reduction reaction will result in reduced intracellular estradiol concentrations. This is because reductive conversion of estrone to active estradiol is reduced or suppressed. Thus, even reversible or irreversible inhibitors of 17β-HSD1 may play an important role in the prevention and / or treatment of steroid hormones, particularly 17β-estradiol dependent diseases or conditions. Furthermore, even reversible or irreversible inhibitors of 17β-HSD1 have or do not have antagonistic binding activity to the estradiol receptor, in particular the estrogen receptor α subtype. It is desirable to have only. This is because estrogen receptor antagonistic binding will result in proliferation and differentiation following activation of the target cell. In contrast, antagonists of estrogen receptors, so-called anti-estrogens, competitively bind to specific receptor proteins, thus inhibiting endogenous estrogens from reaching their specific binding sites.

  At present, it has been described that several malignant diseases such as breast cancer, prostate cancer, ovarian cancer, uterine cancer, endometrial cancer and endometrial hypertrophy can be treated by selective 17β-HSD1 inhibitor administration. Furthermore, selective 17β-HSD1 inhibitors can be useful for the suppression of the aforementioned hormone-dependent cancers, particularly breast cancer (eg WO 2004/080271). In addition, International Patent Application WO2003 / 017973 uses selective estrogen enzyme modulators (SEEMs) in the manufacture of drug delivery vehicles for intravaginal administration, in which benign gynecological diseases, such as the uterus in mammalian females. Describes the use to treat or prevent endometriosis.

  Several reversible or irreversible inhibitors of 17β-HSD1 enzyme of steroidal and non-steroidal origin are already known from the literature. The properties of these inhibitor molecules, mainly having a substrate or cofactor-like core structure, have been reported in the literature [Review: Poirier D (2003)].

  The following compounds or compound classes have already been described as 17β-HSD1 inhibitors. For example, Tremblay and Poirier describe an estradiol derivative, 16- [carbamoyl- (bromo-methyl) alkyl] -estradiol, and the derivative was tested for inhibition of estradiol formation catalyzed by the enzyme 17β-HSD1. [Trembray & Poirier (1998)]. Poirier and colleagues have described 6β-thiaheptane-butyl-methyl-amide derivatives as potent selective inhibitors of the 17β-HSD1 enzyme [Poirier et al. (1998)]. In addition, Poirier and his colleagues described a novel derivative of 17β-estradiol having a long N-butyl, N-methylalkylamide side chain at position 15 with three different lengths (n = 8, 10 or 12). These derivatives can be potential inhibitors of the 17β-HSD1 enzyme [Poirier et al. (1991)]. Similar compounds are also disclosed in European patent application EP 0367576. However, the biological activity of these compounds has been tested only for estrogen receptor binding affinity, estrogenic activity and antiestrogenic activity [Poirier et al. (1996)] but inhibits its 17β-HSD1 enzyme. The ability has not been tested. In addition, Pelletier and Poirier describe novel 17β-estradiol derivatives with various bromo-alkyl side chains, which can be potential inhibitors of the 17β-HSD1 enzyme [Pelletier & Poirier (1996)]. Sam and colleagues have described several estradiol derivatives having an alkyl side chain halogenated at the 16α or 17α position of the steroidal D ring, which have 17β-HSD1 inhibitory properties [Sam Other (1998)]. Furthermore, the finding that some antiestrogens, such as tamoxifen, have weak 17β-HSD1 inhibitory properties suggests that it may be possible to develop potent 17β-HSD1 inhibitors that are also antiestrogens [Review: Poirier D. (2003)]. Some of the previously known compounds also exhibit antiestrogenic properties (eg 6β-thiaheptane-butyl-methyl-amide derivatives of estradiol described by Poirier and colleagues [Poirier et al. (1998)]). The synthesis of 16β-aminopropyl substituted estradiol derivatives as moderate 17β-HSD1 inhibitory compounds has been described by Poirier et al. [Poirier et al., 2002 and Ciobanu & Poirier, 2006]. None of the aforementioned compounds has been used clinically so far.

  Furthermore, international patent application WO 2004/085457 discloses various estrone derivatives with various substituents at positions C2, C3, C6, C16 and / or C17 as potent 17β-HSD1 inhibitors. For some compounds, by substituting a steroidal 17β-HSD1 inhibitor with a small hydrophobic group at the C2 position, the compound is almost non-estrogenic and discrimination is preferred for 17β-HSD1 over 17β-HSD2. [Lawrence et al. (2005)].

  International application WO 2005/047303 discloses novel 3,15-substituted 17β-estradiol derivatives having various types of side chains at position 15, which are both powerful and selective. 17β-HSD1 inhibitor.

  In addition, novel 17β-estradiol derivatives substituted at the 3,15 position and having an additional modification of the steroid nucleus at the C2, C3 and / or C17 positions are potent 17β-HSD1 within the international application WO2006 / 125800. It is described as an inhibitory compound.

  Additional compounds that are potent 17β-HSD1 inhibitors are described in International Applications WO 2006/003012 and WO 2006/003013, which are novel 2-substituted D-homo-estradia-1,3,5 (10) -trienes. And a novel 2-substituted estra-1,3,5 (10) -trien-17-one.

  A more well characterized member of the 17β-HSD family is the 17β-HSD type 3 enzyme (17β-HSD3). 17β-HSD3 has unique characteristics compared to other 17β-HSDs: the enzyme is expressed almost exclusively in the testis, while other isoenzymes are more widely expressed in some tissues. It has been found that 17β-HSD3 has a critical role in androgen biosynthesis. The enzyme converts 4-androsten-3,17-one (A) to testosterone (T). The biological significance of 17β-HSD3 is an inevitable physiological importance. Mutations in the gene for 17β-HSD3 have been found to result in reduced T formation in the fetal testis, thus resulting in a human semi-yin-yang disease called male pseudo-half yin-yang [Geissler et al. (1994). ].

  With respect to the indication of prostate cancer, primary cancer cells maintain androgen responses for some time in regulating proliferation, differentiation and programmed cell death. Currently, androgen blockade is the only effective systemic hormone therapy available for prostate cancer. The development of selective inhibitors for 17β-HSD3 is a new therapeutic approach for the treatment of androgen-dependent diseases [Labrie et al. (2000)]. Furthermore, Ofelein et al. Reported that depot-type GnRH analogs failed to reach castration levels of T in men in nearly 20% of cases [Ofelein MG & Cornum R (2000)]. In order to improve the response rate to endocrine therapy for men with prostate cancer, it may be important to selectively inhibit testicular 17β-HSD3 activity. In addition to prostate cancer, many other androgen sensitive diseases, ie those whose onset or progression is assisted by androgenic activity, can be treated by selectively inhibiting 17β-HSD3 activity. These diseases include but are not limited to prostate pain, benign prostatic hypertrophy, psoriasis, acne, seborrhea, hirsutism, male alopecia, sexual prematurity, adrenal hyperplasia and polycystic ovary syndrome. Absent. Furthermore, in view of the fact that 17β-HSD3 is found primarily in the testis, the development of potent inhibitors would be of interest in blocking spermatogenesis and as a male contraceptive. .

  Acne is a multipathogenic disease caused by the interaction of many factors, such as heredity, sebum, hormones and bacteria. The most important causative factor in acne is sebum production; in almost all acne patients, the sebaceous glands are larger and more sebum is produced than those with healthy skin. Sebaceous gland development and sebum production are hormonally controlled by androgens; therefore, androgens play a critical role in acne pathogenesis. In humans, there are two major sources for supplying androgen to the target tissue: (i) gonads that secrete testosterone, (ii) secreted as sulfate conjugates (DHEAS) dehydroepiandrosterone It is an adrenal gland that produces (DHEA). Testosterone and DHEAS are both converted to dihydrotestosterone (DHT), the most active androgen in target tissues, such as skin. There is evidence that the route of local synthesis of DHT in these skins is more important than supplying active androgens directly from the circulatory system. Therefore, reducing endogenous levels of androgen in target tissues with certain inhibitors should be therapeutically useful in acne and seborrhea. In addition, the prospect of treating the above-mentioned diseases by regulating local androgen levels by local treatment, rather than affecting circulating hormone levels by systemic treatment, is opened.

  Male alopecia is very common in white people and accounts for about 95% of all alopecia types. Male pattern alopecia is caused by an increased number of hair follicles in the scalp that enter a resting period and a long lasting resting period. It is a genetically determined hair loss that is acted on through androgens. Increased serum DHEA but normal testosterone levels have been reported in bald men compared to non-bald control groups, indicating that target tissue androgen production is important for male alopecia It is implied.

  Hypertrichosis is a physiological hair thickening and enhancement characterized by male and female masculine hair growth in children and women. Hypertrichosis is induced by androgen, either by increased formation of androgen or by increased sensitivity of hair follicles to androgen.

  Several reversible or irreversible inhibitors of steroid-derived and non-steroidal 17β-HSD3 enzymes are already known from the literature. The properties of these inhibitory molecules are described in the literature [Review: Poirier D. (2003)]. Furthermore, international patent application WO 01/42181 discloses benzyltetralines related to the chemical structure of biocanin whose chemical structure is phytoestrogens as 17β-HSD3 inhibitors. Furthermore, international patent applications W099 / 46279, W02003 / 022835, W02003 / 033487, W02004 / 044611, W02004 / 060488, W02004 / 1104959, W02005 / 032527 and W02005 / 084295 are hormone sensitive diseases. Disclosed are compounds having 17β-HSD3 inhibitory activity for therapy.

  Human endometrial and placental microsomal 17β-hydroxysteroid dehydrogenase (referred to as 17β-HSD type 2 or 17β-HSD2) has been cloned by expression cloning, which uses androgens and estrogens as substrates for oxidation. Were found to be equally active [Andersson (1995)]. Recombinant 17β-HSD2 converts highly active 17β-hydroxy steroids such as estradiol (E2), testosterone (T) and dehydrotestosterone (DHT) into their inactive keto forms. Furthermore, the 17β-HSD2 can also convert 20β-hydroxyprogesterone (20βP) to progesterone (P) to a lesser extent. Its extensive tissue distribution, along with the major oxidative activity of 17β-HSD2, is essential for the enzyme to inactivate highly active 17β-hydroxysteroids and reduce sex hormone activity in the target tissue. This suggests that the role of Dong and colleagues demonstrated that they show large 17β-HSD2 activity in cultured human osteoblasts and osteoblast-like osteosarcoma cells MG63 and TE85, but not in SaOS-2. [Dong et al. (1998)]. The ability of interconversion by bone cells from E1 to E2, T to A, and DHT to A is therefore an intracellular ligand for estrogen and androgen receptors in osteoblasts and other steroid sensitive cells. It is an important mechanism for local regulation of supply. This regulation of steroid levels is for a wide variety of indications, including the following: for the prevention and treatment of osteoporosis, for the treatment of ovarian cancer, breast cancer or endometrial cancer, for the treatment of prostate cancer And / or for the treatment of androgen-dependent hair loss.

  Several reversible or irreversible inhibitors of steroid-derived and non-steroidal 17β-HSD2 enzymes are already known from the literature. The properties of these inhibitory molecules are described in the literature [Review: Poirier D. (2003)]. Furthermore, international patent application WO 02/26706 discloses 17β-HSD2 inhibitors of non-steroidal origin.

  Furthermore, 17β-HSD1, 17β-HSD2 or 17β-HSD3 inhibitors reduce further estrogen-dependent or androgen-dependent diseases or disorders and / or systemically or tissue-specific endogenous estrogen or androgen levels Diseases or disorders that need to be treated, such as inflammatory and autoimmune diseases such as rheumatoid arthritis, type 1 and type 2 diabetes, systemic lupus erythematosus, multiple sclerosis, myasthenia gravis, thyroiditis, vasculitis Useful for the prevention and treatment of ulcerative colitis and Crohn's disease, psoriasis, contact dermatitis, eczema, tissue wounds, skin wrinkles and / or cataracts, asthma, graft-versus-host disease and organ rejection after transplantation It may be. 17β-HSD inhibitors are also considered useful for enhancing cognitive function, particularly in the treatment of senile dementia, including Alzheimer's disease. Additional estrogen-dependent diseases that can be treated and / or prevented with an effective amount of a compound of the invention are squamous cell carcinoma and colon cancer.

Several different types of estrogen or androgen derivatives are disclosed in the literature as inhibitors or activators of further enzymes of sex steroid conversion:
For example, related US Pat. Nos. 5,571,933, 5,677,292, and 5,866,603 disclose inhibitors of the steroid sulfatase enzyme, wherein the compound is , An estrone derivative having an —NH—SO ₂ -aryl side chain, —NH—CO— (C ₁ -C ₆ -alkyl) side chain or —NH—CO—CF ₃ side chain at the C3 position of the steroid nucleus.

  In addition, US Pat. No. 6,541,463 discloses androgen and estratriene derivatives mainly having modifications at the C17 position, which contain inhibitors of 17β-HSD5 enzyme and optionally additionally 17β- Developed as an inhibitor of the HSD3 enzyme. Some disclosed examples (EM-1404, EM-1403, EM-1401, EM1388) have a carboxy, carboxymethyl or amide group at the C3 position of the steroid nucleus. However, these compounds have been developed as selective inhibitors of the 17β-HSD5 enzyme and do not show the large inhibitory ability of the 17β-HSD1, 17β-HSD2 or 17β-HSD3 enzyme.

The synthesis of various estradiol carboxylic acid esters substituted with B, C and D rings has been described by Labare et al. [2003]. However, these esters were only analyzed for their estrogenic potential. A related international patent application WO 2004/085345 describes — (CH ₂ ) _m —CO—O—R side chain wherein R is a H, C ₁ -C ₅ -alkyl group and optionally at least one. Substituted with a halogen group of, for example, CH ₂ CH ₂ F or another group (for example, CH ₂ CHF ₂ , CH ₂ CF ₃ or CF ₃ group, and m is 0 to 5). Disclosed is an estradiol compound substituted at the 15α position. These 15α-estradiol esters are described as locally active estrogens and have no significant systemic effects.

  Estratriene derivatives with D-ring modifications as dual inhibitors of 17β-HSD1 and steroid sulfatase enzymes are described in International Patent Application WO 02/32409.

  International patent application WO 2004/084559 discloses various estrone derivatives with various substituents at positions C2, C3, C4 and / or C17 as potent steroid sulfatases.

  Furthermore, international patent application WO 2006/027347 discloses 15β-substituted estradiol derivatives having estrogen receptor activity selective for the estrogen receptor α subtype.

  Estrone and estradiol derivatives having a boronic acid substitution at the C3 position have recently been disclosed by Ahmed et al. As inhibitors of the steroid sulfatase enzyme [Ahmed et al. (2006)].

  Therefore, the above mentioned steroid hormone-dependent diseases or disorders are still preferably treated while the selective inhibition of the 17β-HSD1, 17β-HSD3 or 17β-HSD2 enzyme depending on the disease to be treated, while preferably 17β- There is a need for the development of compounds suitable for treatment and / or prevention by substantially failing to inhibit other members of the HSD protein family. In particular, the object of the present invention is a selective inhibitor of the 17β-HSD1 enzyme, which further has no or slightly pure antagonistic binding affinity for the estrogen receptor (both subtype α and β). It is to develop something that only has. Preferably, the selective inhibitor of 17β-HSD1 enzyme is not capable of inhibiting the 17β-HSD2 enzyme. Furthermore, the increased metabolic stability of the compounds is desirable to suppress the conversion of the compounds into metabolites that have little inhibitory capacity for the 17β-HSD1 enzyme.

Introduction of the R ¹¹ substituent at the C2 position, if present in the final compound, must first be done starting from 17β-estradiol using methods well known to those skilled in the art (step A ). In parallel, the C17-OH function is oxidized to the corresponding keto function. If necessary, suitable protecting groups can be introduced at this point to protect the oxygen at the C3 position. The estrone derivative of formula (V) is then converted into the major intermediate, ie, the 15,16-unsaturated estrone of formula X (Step B), which is further converted to a basic side chain at the C15 position ( Derivatization by introduction of "so-called structural units"). These building blocks are reacted with a suitable compound having an R ² / R ⁴ substituent to give the desired C15 substituted compound (Step C). If desired, the resulting starting material can be further modified within the C17 position by exchange of oxygen and difluoro groups (Step D). Finally, the protecting group at the C1 position is replaced with a selective R ¹ side chain to give a compound of the invention (Step E).

  In order to synthesize several compounds of the present invention and to allow library synthesis, some of the reaction steps described in “Step C—Introduction of the C15 Side Chain” are described in the following general synthetic scheme: As shown in II, it may be necessary to carry out after introducing a difluoro group at C17 and / or after introducing a new substituent (or an intermediate thereof) at the C3 position.

Introduction of the R ¹¹ substituent at the C2 position, if present in the final compound, must first be done starting from 17β-estradiol using methods well known to those skilled in the art (step A ). In parallel, the C17-OH function is oxidized to the corresponding keto function. If necessary, suitable protecting groups can be introduced at this point to protect the oxygen at the C3 position. The estrone derivative of formula (V) is then converted to the major intermediate, ie, the 15,16-unsaturated estrone of formula X (Step B), which is further converted to a basic acid, alcohol at the C15 position. By derivatization by introducing a side chain of amide or alkenyl, a so-called structural unit is obtained (step C (I)). A difluoro group can then be introduced at the C17 position of the steroid nucleus (step D). Alternatively or additionally, a boronic acid group or carboxylic acid group or amino group may be introduced at the C3 position in this step (step E). The structural unit thus obtained is reacted with a suitable compound having an R ² / R ⁴ substituent to give the desired C15 substituted compound (step C (II)). Finally, the protecting group at the C1 position is replaced with an optional R ¹ side chain to give the compounds of the invention (Step E), or any still required modification at the C3 position is performed.

Step A—Introduction of the R ¹¹ Side Chain at the C2 Position of 17β-Estradiol or Estrone The optional “Step A” modification is fully disclosed in International Patent Application WO2006 / 125800.

［式中、Ｒ¹¹は、本願に定義される意味を有し、かつＰＧは、通常の保護基である］。

[Wherein R ¹¹ has the meaning as defined herein, and PG is a normal protecting group].

The introduction of various side chains in the estrone core is known from the literature, for example Rao et al. (2002) describe the synthesis of 2-methoxyestradiol and the synthesis of 2-ethoxy-estradiol is Verdier- Pinard et al. (2000). 2-Ethyl-estrone is obtained from estrone by acetylation of Friedel-Crafts of estrone-3-O-methyl ether, catalytic hydrogenation, followed by demethylation to yield the desired product. It can be manufactured by generating. Optionally, introduction of a substituent at the 2-position is as described by Rao et al. (2002), starting with estradiol and the reagent (RCO) ₂ O, where R = lower alkyl. Can be achieved by using the Fries rearrangement: after acylation, it is desirable to convert the compound to an R-CO substituted derivative at the C2 position. Reduction of the acyl function can be achieved by reduction with Pd / C and H ₂ [Gonzalez et al. (1982)]. Alternatively, the acetoxy group at the C2 position could be oxidized according to [Yoshikawa et al. (2002)] with PhI (CF ₃ CO ₂ ) ₂ . An alkoxy-alkyl substituted estradiol derivative can be obtained by further alkylating the newly introduced hydroxy group and subsequently reducing the ketone. An alternative strategy for introducing an alkoxy-alkyl group is illustrated for the methoxy-ethyl group. After MOM protection of 17β-estradiol, the MOM protected estradiol is iodinated [Mohanaklishnan & Cushman (1999)]. The MOM group is then exchanged for the TBDMS group. Negishi coupling with allyl bromide yields 2-allyl substituted estrone derivatives, which can be oxidized and methylated (including handling of several protecting groups). Additional synthetic routes to 2-alkyl substituted estrone or estradiol derivatives have been shown so far [see, eg, Mohanakrishnan & Cushman (1999); Day et al. (2003); Cushman et al. (1995) and Lunn & Farkas (1968). ]. The synthesis of additional estrone derivatives with various substituents at the 2-position is disclosed by Cushman et al. (2002).

During the introduction of the C2 side chain, the 3-hydroxy function of the steroid core is generally protected with a methyl or benzyl group (exemplified by PG). For example, methyl derivatives can be prepared using MeI and acetone, while the corresponding benzyl derivatives can be prepared using benzyl bromide, DIPEA and acetone. Enone derivatives having other substituents in R ¹ (= PG), in particular optionally substituted C ₁ -C ₄ -alkyl, are therefore preferably optionally substituted C ₁ -C ₄ -alkyl-bromides Alternatively, it can be prepared using C ₁ -C ₄ -alkyl-iodides.

Step B—Synthesis of 15,16-Unsaturated Estrone of Formula X (Intermediate I)
The “Step B” reaction is fully disclosed in International Patent Application WO 2005/047303 for estrone and in WO 2006/125800 for C2-substituted estrone derivatives.

  Starting from the corresponding disubstituted estrone of formula (V), the ketal of formula (IX) can be prepared according to Nambara [Nambara et al. (1976)] as shown in Scheme 1 below. . If not already protected, introduction of the PG group at the C3 position can be accomplished according to the procedure described by Labare (2003).

［式中、Ｒ¹¹は、本願に定義される意味を有し、かつＰＧは、通常の保護基である］。

[Wherein R ¹¹ has the meaning as defined herein, and PG is a normal protecting group].

  The C17 keto function of the C2-substituted protected estrone derivative of formula (V) is protected as an acetal and subsequently brominated. Release of the bromide yielded the desired 15,16-unsaturated estrone. Finally, a suitable enone derivative X is obtained by hydrolyzing the ketal derivative.

  Alternatively, the enone intermediate of formula X can be prepared from the corresponding estrone derivative according to the method described by Poirier et al. (1991).

Step C-Introduction of side chain at C15 position
A variant of “Step C” (introduction of the side chain at the C15 position) is carried out in two main steps. In the first step C (I), the 15,16-unsaturated estrone of formula X is converted into a so-called building unit having an alkyl side chain at the C15 position and a terminal amino, carboxy or alcohol function. The synthesis of some exemplary building blocks is shown in the experimental section "intermediate", which is about C2 substituted for almost all types of building blocks, with respect to estrone in international patent application WO2005 / 047303. The estrone derivatives are fully disclosed in WO 2006/125800. How to obtain an estrone intermediate with an azide or alkyne side chain at the C15 position is disclosed in the unpublished international patent application PCT / EP2007 / 059785.

  A second step C (II) of the modification of “Step C” (conversion of the building block to the desired derivative with the complete side chain at the C15 position) is the following synthetic scheme shown in flow diagrams I-XV: Illustrated below by using one. Again, the synthesis of some exemplified intermediates with specific side chains or even final compounds of formula (I) is shown in the experimental section "Intermediate" or in "Examples". The synthesis of a variety of different C15 side chains is fully disclosed in international patent application WO 2005/047303 for estrone and in WO 2006/125800 for C2-substituted and / or C17 modified estrone derivatives.

Protected amine building block XV-1 (n = 1) :
The individual steps in the synthesis of the amine building block of formula XV-1 are shown in Scheme 17 below.

Because of the instability of these ammonium salts, standard purification methods did not work. For these amines, it is known that although the free amine is not stable (eneamine), its salt is at least even heat sensitive and so it is desirable to treat it as the HCl salt. The crude reaction mixture has a purity of ˜90% (HPLC-MS).

Amine building blocks XVα-3, XVα-4, XVα-5 and XVα-6
The individual steps in the synthesis of the amine building block of formula XVα-3 are shown in Scheme 18 below.

The individual steps in the synthesis of an amine building block of formula XVβ-4 / 5/6 having a β configuration at the C15 atom of the steroid core are shown in Scheme 19 below:

  In the first step, the 17 oxo function (with respect to the synthesis of XXXIβ) of the butanol derivative of formula XXXIβ is converted to a ketal group (compound of formula XXXIIβ). The alcohol function is then selectively reduced to an aldehyde to give a compound of formula XIIIβ. The protected aldehyde derivative of formula XIIIβ is converted to the secondary amine by addition of benzylamine followed by reduction (reductive amination). Further reduction of the secondary amine provides the desired, still protected amine building block of formula XVβ. Ketal protecting groups can be converted via acid hydrolysis to 17-oxo groups.

The functionality does not require any protection according to the following general scheme 20.

  After protection by mesylation of the alcohol, an azidation reaction can be carried out. If desired, the azide is then further reduced to the corresponding amine.

Recombinant 17β-HSD1 or 17β-HSD2 bacmid was transfected into Sf9 insect cells using “Cellfectin Reagent” (Invitrogen). After 60 hours, cells were harvested and fractions containing 17β-HSD1 or 17β-HSD2 were isolated as described by Puranen et al. (1994). Multiple aliquots were stored frozen until measurement of enzyme activity.

Inhibition of recombinant human 17β-HSD1 or 17β-HSD2
Recombinant 17β-HSD1 assay : Recombinant protein homogenate (0.1 μg / ml) was added to 20 mM KH ₂ PO ₄ (pH 7.4) reaction buffer, protease inhibitor (Complete Protease Inhibitor Cocktail table, Roche Diagnostics) 1697498), 30 nM estrone (Sigma, E9750) as a substrate, 800000 cpm / ml ³ H-estrone (Perkin Elmer, NET 319001MC) as a tracer substrate, and 1 mM NADPH (Sigma, N1630) Those with cofactors were incubated in the presence of potential inhibitors at a concentration of 1 μM or 0.1 μM for 30 minutes at room temperature. Inhibitor stock solutions were prepared in DMSO. The enzymatic reaction was stopped by the addition of trichloroacetic acid (1% final concentration). Samples were centrifuged for 10 minutes at 4000 rpm in a microtiter plate. The supernatant was applied to reverse phase HPLC with a Waters Symmetry C18 type column equipped with a Waters Sentry Guard type column. An isocratic HPLC run was performed at a flow rate of acetonitrile: water (48:52) as the running solvent at room temperature at 1 ml / min. Radioactivity was monitored in the eluate by a Packard flow scintillation analyzer. Total radioactivity for estrone and estradiol was measured in each sample and the percent inhibition of estradiol conversion by each inhibitor was calculated.

3. Estrogen Receptor Binding Assay The binding affinity of compounds of the invention for estrogen receptor α and estrogen receptor β can be measured according to the in vitro ER binding assay described by Koffman et al. (1991). Alternatively, estrogen receptor binding assays can be performed according to international patent application WO 00/07996.

4). Estrogen Receptor Transactivation Assay Compounds of the present invention that exhibit binding affinity for the estrogen receptor can be further combined with their individual estrogenic or anti-estrogenic potential (agonist or antagonist binding to ERα or ERβ). Can be tested. Measurement of estrogen receptor agonist activity can be performed by an in vitro assay system using the MMTV-ERE-LUC reporter system (eg described in published US patent application US2003 / 0170292).

  For assay of estrogen receptor agonist activity, Hela cells were grown in 24-well microtiter plates and then transiently co-transfected with Lipofectamine in two plasmids. The first plasmid contains DNA encoding the human estrogen receptor (either ERα or ERβ), and the second plasmid contains an estrogen-driven reporter system, the reporter system comprising mouse mammary tumor virus (MMTV) contains a luciferase reporter gene (LUC) transcribed under the control of an upstream regulatory element containing 4 copies of the vitellogenin estrogen response element (ERE) cloned into the promoter (the generic name of the reporter system is "MMTV- ERE-LUC "). Cells were cultured at 37 ° C. for 42-48 hours in RPMI 1640 medium supplemented with 10% activated carbon-treated calf serum, 2 mM L-glutamine, 0.1 mM non-essential amino acids and 1 mM sodium pivalate. The compounds of the present invention were exposed in a% carbon dioxide incubator. At the same time, cells exposed to estradiol (1 nM) are provided as a positive control. Repeat test wells exposed to the solvent in which the compound of the invention is dissolved (ie ethanol or methanol) are used as negative controls. After a 42-48 hour incubation period, the cells are rinsed with phosphate buffered saline (PBS), lysis buffer (Promega) is added, and the cell lysate is collected and luciferase activity is measured using a luminometer. taking measurement. The estrogenic activity of the compounds of the present invention is expressed as a fold increase in luciferase activity compared to that observed in negative control cells.

Can be implemented.

Conclusion The compounds of the present invention show good inhibitory ability of 17β-HSD1, 17β-HSD2 and / or 17β-HSD3 enzymes. As explained in more detail above, the compounds of the invention are therefore considered suitable for the treatment of several estrogens and androgens dependent diseases and disorders, respectively. In particular, some malignant and benign pathologies, such as breast cancer, endometriosis and uterine fibroids, are all 17β-estradiol dependent, so the endogenous 17β-estradiol concentration in the respective tissue, for example by inhibition of the 17β-HSD1 enzyme, is increased. The reduction results in a loss or reduction in the growth of 17β-estradiol dependent cells in the tissue, as can be demonstrated by the in vivo assay described above. Thus, the selective inhibitors of the 17β-HSD1 enzyme described in the present application are highly effective for the reduction of endogenous production of estrogens, particularly 17β-estradiol, in myomas, endometrial tissues, adenomyoma tissues and endometrial tissues. Is suitable. Application of a compound that acts as a selective inhibitor on the 17β-HSD1 enzyme that catalyzes a reductive reaction causes a decrease in intracellular estradiol concentration. This is because the reductive conversion of estrone to the active form of estradiol is reduced or suppressed, thus the proliferation of 17β-estradiol dependent cells in malignant or benign tissues is diminished or even reduced. Because.
