Abstract
Description
[Technical field]
[0001] FIELD OF THEINVENTION The present invention relates to a novel class of aldo-keto reductase family 1C3 (AKR1C3) (also known as 17β-hydroxysteroid dehydrogenase type 5 (17β-HSD5, HSD17B5) and prostaglandin (PG)F2α synthase) inhibitors, their salts, solvates and solvates of the salts, as well as pharmaceutical compositions comprising these compounds as active ingredients. The invention further relates to methods for their preparation and their use. [Background technology]
[0002] 2. Background of the Invention Aldo-keto reductase family 1 member C3 (AKR1C3) inhibits 17β-hydroxysteroid dehydrogenase type 5 (17β-HSD5, HSD17B5) and prostaglandin (PG) F 2α Also known as synthase. AKR1C3 is a member of the aldo-ketoreductase 1C (AKR1C) subfamily of the aldo-ketoreductase (AKR) superfamily of enzymes, which contains >190 members. The human AKR1C subfamily consists of four isoforms (AKR1C1, -C2, -C3 and -C4) and is a phase I metabolic enzyme that depends on nicotinamide adenine dinucleotide phosphate (NADPH) for the reduction of 3-keto-, 17-keto- and 20-ketosteroids. AKR1C3 also reduces the carbonyl group of steroid hormones to the corresponding alcohols and therefore plays an important role in the metabolism, activation and deactivation of androgens, estrogens, progesterone and prostaglandins.
[0003] AKR1C3 shares high sequence homology (>86%) with AKR1C1, -C2 and -C4. Although the isoforms are similar in structure, the isomers are differentially distributed and exhibit distinct biological functions. AKR1C3 shows endocrine organ expression, including liver, GI tract, prostate, testis, adrenal gland, uterus, breast, lung, kidney, bladder, ovary, adipose tissue and brain.
[0004] More specifically, AKR1C3 can catalyze the conversion of estrone (a weak estrogen) to estradiol (a strong estrogen), progesterone (strong antiestrogenic activity) to 20-α-hydroxyprogesterone (weak antiestrogenic activity), dehydroepiandrosterone (DHEA, a weak androgen) to androstenediol (the precursor of testosterone), androstenedione (a weak androgen) to testosterone (a strong androgen), 5α-androstanedione (5α-dione, a weak androgen) to DHT (a strong androgen), and androsterone to 17β-dihydroandrosterone (Penning et al. Mol. Cell. Endocrinol. 2006, 248 (1-2), 182-191; Rizner TL, Pen-ning TM. Steroids 2014; 79: 49-63). In addition, AKR1C3 has enzymatic activity against the 11-keto forms of androgens, and is therefore capable of converting 11-ketoandrostenedione (a weak androgen) to 11-ketotestosterone (a strong androgen), 11-keto-5α-androstanedione to 11-keto-5α-dihydrotestosterone, and 11-ketoandrosterone to 11-keto-3α-androstanediol (Barnarda M. et al. J. Steroid Biochem. Mol. Biol. 2018; 183: 192-201; Schiffer L et al. Eur. J. Endocrinol. 2021; 184: 357-67; Storbeck KH et al. Mol. Cell Endocrinol. 2013; 377: 135-46). AKR1C3 is also PGH 2 From PGF 2α and PGD 2 From 11β-PGF 2and , both of which are known to stimulate inflammation and proliferation (Byrns M. et al., Biochem. Pharmacol. 2008, 75 (2), 484-493; Byrns M et al. J. Steroid Biochem. Mol. Biol. 118 (2010) 177-187; Penning TM. Mol. Cell Endocrin. 2019; 489; 82-91; Suzuki-Yamamoto T. et al. FEBS Lett. 462 (1999) 335-340; Komoto J et al. Biochemistry 45 (7) (2006) 1987-1996). Inhibition of AKR1C3 activity therefore reduces the levels of these end products and, as a result, AKR1C3 may mediate the regulation of ligands for androgen, estrogen, progesterone and prostaglandin receptors.
[0005] Furthermore, AKR1C3 has also been shown to metabolize a wide range of carbonyl compounds and xenobiotics. AKR1C3 as a carbonyl reductase can mediate anthracycline inactivation and resistance (Bukum N. et al. Chem.-Biol. Interact. 2019, 302, 101-107; Zhong et al. Biomed. Pharmacother. 2015, 69, 317-325; Hofman J. et al. Toxicol. Appl. Pharmacol. 2014, 278 (3), 238-248), and AKR1C3 as a nitroreductase can mediate the inactivation and resistance of nitrogen mustard anticancer drugs, such as PR-104A (Bortolozzi R. et al. Br. J. Cancer 2018, 118 (7), 985-994) and OBI-3424 / TH3424 (Evans K. et al. Clin. Cancer Res. 2019, 25 (14), 4493-4503) can be induced.
[0006] There is a need in the art for new compounds that inhibit AKR1C3. As mentioned above, AKR1C3 mediates the regulation of ligands of androgen, estrogen, progesterone and prostaglandin receptors, therefore, inhibition of AKR1C3 activity can reduce the levels of these end products, such that such AKR1C3 inhibitors are suitable for the treatment and / or prevention of diseases and disorders associated with altered levels of androgens, estrogens, progesterone and / or prostaglandins.
[0007] AKR1C3 inhibitors have been previously published. The most potent inhibitor published inhibited AKR1C3 with an IC of 0.035 ± 0.002 μM. 50 The pyridine derivative GTx-560 inhibits AKR1C3 at the IC level (Clin. Cancer Res. 2013, 19, 20; 5613-5625). 50 A flufenamic acid analogue with a potency of 35 nM was published in Heindriks et al., Bioorg. Med. Chem. Lett. 2015, 25 (20), 4437-4440. Furthermore, patent application EP3421483A1 discloses AKR1C3 inhibitors that are steroidal 17-beta heteroaryl compounds. One of the disclosed compounds is BAY-1128688, which was included in a Phase II clinical trial for the treatment of endometriosis, but increased bilirubin levels in patients and the trial was discontinued.
[0008] Additionally, morpholinyl ureas have been disclosed as AKRIC3 inhibitors; for example, the morpholinyl urea compound SN34037 has an IC 50 (Flanagan et al., Bioorg. Med. Chem. 2014, 22 (3), 967-977). Furthermore, among the published sulfonylurea compounds, glimepiride (GLM) has an AKR1C3 IC value of 0.85 μM. 50(Zhao Y. et al., Chem.-Biol. Interact. 2015, 240, 310-315). Many AKR1C3 inhibitors have been shown to inhibit other AKR and COX enzymes (Yang et al, J. Med. Chem. 2020, 63, 20, 11305-11329).
[0009] Due to the countervailing biological functions of certain closely related enzymes in the aldo-keto reductase (AKR) or hydroxysteroid (17β) dehydrogenase (HSD17B) enzyme family, it is beneficial to develop AKR1C3 inhibitors that selectively inhibit AKR1C3 over other AKRs or HSD17B. For example, in the prostate, AKR1C2 plays an important role in inactivating 5α-dihydrotestosterone. Meanwhile, AKR1C2 inhibition in prostate cancer can promote proliferative signaling in the prostate, and treatment of prostate carcinoma can be achieved by AKR1C3 inhibition. Therefore, isomer-selective AKR1C3 inhibitors are needed (Penning TM et al. Mol. Cell Endocrinol. 2008, 281, 1-8). On the other hand, type 2 17β-hydroxysteroid dehydrogenase (HSD17B2) induces steroid metabolism in the opposite direction to AKR1C3, converting potent steroid-like estradiol, testosterone and 5α-dihydrotestosterone to the less active forms estrone, androstenedione and 5α-androstanedione, respectively (Gao X. et al. Clin. Cancer Res. 2019, 25, 1291-301; Ko H. et al. Cell Rep. 2018, 22, 809-819). Its widespread and abundant expression in several different estrogen and androgen target tissues, such as uterus, placenta, liver and the digestive and urinary tracts, suggests that type 2 enzyme protects tissues from excessive steroid action. Therefore, it is important to have selective AKR1C3 inhibitors. Summary of the Invention [Problem to be solved by the invention]

Cycloalkyl may be substituted on any suitable ring atom with 1 to 6, preferably 1 or 2, substituents as indicated, especially 1. Preferred substituents are halogen, especially F and Cl, cyano, methyl, ethyl, acetyl, trifluoromethyl, hydroxy, methoxy, OCF 3 , C.H. 2 OH, CH 2 OCH 3 , C.H. 2 CH2 OH, CH 2 CH 2 CH 2 OH, OCH 2 CH 3 , 1-hydroxyethyl, SO 2 NH 2 and acetyl.
[0027] The term "heterocyclyl" is used to refer to saturated or partially unsaturated mono-, bi-, tri-, and tetracyclic rings having one or more heteroatoms as ring atoms, with the remaining ring atoms being carbon atoms. Thus, for example, "3- to 10-membered heterocyclyl" refers to saturated or partially unsaturated mono-, bi-, and tricyclic rings having a total of 3 to 10 ring atoms, of which one or more ring atoms are heteroatoms, and the remaining ring atoms are carbon atoms. Preferably, the heterocyclyl has 1 to 6 heteroatoms as ring atoms, more preferably 1 to 4 heteroatoms, with the remaining ring atoms being carbon atoms, where the heteroatoms include at least the heteroatoms indicated in the same context, and optionally one or more additional heteroatoms. Each heteroatom is independently selected from N, S, O, P, Si, and Se, preferably N, O, and S, unless otherwise specified.

Heterocyclyl may be substituted at any suitable ring atom, including N, with 1 to 6, preferably 1 or 2, and especially 1, substituents as indicated. Preferred substituents are halogen, especially F and Cl, cyano, methyl, ethyl, acetyl, trifluoromethyl, hydroxy, methoxy, OCF 3 , C.H. 2 OH, CH 2 OCH 3 , C.H. 2 CH 2 OH, CH 2 CH 2 CH 2 OH, OCH 2 CH 3, 1-hydroxyethyl, SO 2 NH 2 and acetyl.
[0028] "Optionally" or "optionally" means that the subsequently described event or circumstance may occur, but does not have to occur, and the description includes instances where the event or circumstance occurs and instances where it does not occur.
[0029] The term "optionally substituted" as used herein and hereinafter means that the group with which it is described is unsubstituted or independently substituted with 1 to 6, preferably 1, 2, 3 or 4, substituents attached to any available atom to yield a stable compound. For example, phenyl is substituted once with the described substituent attached to the o-, m- or p-position of the phenyl ring. In general, unless otherwise specified, "substituted" refers to a substituent (group), as defined herein and hereinafter, in which one or more bonds to a hydrogen atom contained therein are replaced with a bond to a non-hydrogen atom.
[0030] The term "unsaturated or aromatic heterocycle" refers to unsaturated or aromatic mono-, bi-, tri-, and tetracyclic rings having one or more heteroatoms as ring atoms, with the remaining ring atoms being carbon atoms. Thus, for example, "4- to 11-membered unsaturated or aromatic heterocycle" refers to unsaturated or aromatic mono-, bi-, and tricyclic rings having a total of 4 to 11 ring atoms, of which one or more ring atoms are heteroatoms, with the remaining ring atoms being carbon atoms. Preferably, the unsaturated or aromatic heterocycle has 1 to 6 heteroatoms, more preferably 1 to 4 heteroatoms, each independently selected from the group consisting of N, S, and O, as ring atoms, with the remaining ring atoms being carbon atoms.
