 本発明は、エストロゲン関連受容体アルファ[Estrogen Related Receptor-α(本明細書中、ERRαと略記することがある)]モジュレーターとしての優れた活性を有し、悪性腫瘍(例、乳癌、悪性リンパ腫、多発性骨髄腫、前立腺癌、大腸癌、肺癌、卵巣癌、子宮内膜癌)などのERRα関連疾患の予防、治療薬として有用な新規化合物に関する。 The present invention has an excellent activity as an estrogen-related receptor alpha [Estrogen Related Receptor-α (in this specification, sometimes abbreviated as ERRα)] modulator, and a malignant tumor (eg, breast cancer, malignant lymphoma, The present invention relates to a novel compound useful as a preventive or therapeutic agent for ERRα-related diseases such as multiple myeloma, prostate cancer, colon cancer, lung cancer, ovarian cancer, endometrial cancer).
(発明の背景)
 核内受容体は、発生・分化といった生理的因子あるいは環境因子等の種々の刺激に応答してリガンド依存的に遺伝子発現を調節する転写制御因子であり、その構造上の特徴から遺伝子スーパーファミリーを形成する。その中には、エストロゲンをリガンドとするエストロゲン受容体(ER)等の古典的な核内受容体、およびリガンドや生理学的機能が未知のオーファン核内受容体が含まれる。
(Background of the Invention)
Nuclear receptors are transcriptional regulators that regulate gene expression in a ligand-dependent manner in response to various stimuli such as physiological factors such as development and differentiation, or environmental factors. Form. These include classical nuclear receptors such as estrogen receptor (ER) with estrogen as a ligand, and orphan nuclear receptors whose ligands and physiological functions are unknown.
 エストロゲン関連受容体アルファ(ERRα、NR3B1)は、ERに密接に関係するオーファン核内受容体であるエストロゲン関連受容体サブファミリー(ERRサブファミリー)に属する。ERRサブファミリーのメンバーとしては、他に、ERRβおよびERRγが同定されており、その全てが、DNA結合ドメインにおいてERと高い相同性を有する。ERおよびERRサブファミリーは、エストロゲン応答性遺伝子等の標的遺伝子を共有することが知られている。 Estrogen-related receptor alpha (ERRα, NR3B1) belongs to the estrogen-related receptor subfamily (ERR subfamily) which is an orphan nuclear receptor closely related to ER. Other members of the ERR subfamily have been identified as ERRβ and ERRγ, all of which have high homology with ER in the DNA binding domain. The ER and ERR subfamilies are known to share target genes such as estrogen responsive genes.
 ERとERRサブファミリーのシグナル伝達経路間には、クロストーク(crosstalk)が生じる(非特許文献1~4)。従って、ERRαの活性を調節し得る化合物(ERRαモジュレーター)は、ERRαの転写効果を直接調節することにより、あるいはERシグナル伝達経路への間接的効果により、ERRαおよびERに関連する疾患の両方に対して治療的効果を有し得る。 Crosstalk occurs between the signal transmission pathways of the ER and ERR subfamily (Non-Patent Documents 1 to 4). Thus, compounds that can modulate the activity of ERRα (ERRα modulators) are directed against both ERRα and ER-related diseases by directly modulating the transcriptional effects of ERRα or by indirect effects on the ER signaling pathway. Can have a therapeutic effect.
 ERRαの広範な活性を考慮すると、ERRαモジュレーターは、様々な疾患状態(例えば、乳癌などの癌、糖尿病、高脂血症、肥満、代謝症候群、関節炎、アテローム性動脈硬化症、関節リウマチ、アトピー性皮膚炎、骨粗鬆症、不安、抑うつ、パーキンソン病、アルツハイマー病等)の治療または予防において有用であることが期待される(特許文献1、2、非特許文献5)。 In view of the widespread activity of ERRα, ERRα modulators are found in various disease states (eg, cancer such as breast cancer, diabetes, hyperlipidemia, obesity, metabolic syndrome, arthritis, atherosclerosis, rheumatoid arthritis, atopic) It is expected to be useful in the treatment or prevention of dermatitis, osteoporosis, anxiety, depression, Parkinson's disease, Alzheimer's disease, etc. (Patent Documents 1, 2, Non-Patent Document 5).
 近年、ERRα阻害活性を有するsiRNAおよび低分子化合物によって、マウスモデルにおけるエストロゲン受容体陽性および陰性乳癌に対する良好な抗腫瘍効果が得られることが報告された(非特許文献6、7)。 Recently, it has been reported that siRNA and low molecular weight compounds having ERRα inhibitory activity can provide good antitumor effects against estrogen receptor positive and negative breast cancer in a mouse model (Non-patent Documents 6 and 7).

The present invention is further explained in detail by the following examples, test examples and formulation examples, which are not intended to limit the present invention, and may be changed without departing from the scope of the present invention.
“Room temperature” in the following examples usually indicates about 10 ° C. to about 35 ° C. The ratio shown in the mixed solvent is a volume ratio unless otherwise specified. Unless otherwise indicated, “%” indicates “% by weight”.
In the silica gel column chromatography, when described as NH, aminopropylsilane-bonded silica gel was used. In HPLC (high performance liquid chromatography), when it was described as C18, octadecyl-bonded silica gel was used. The ratio of elution solvent indicates a volume ratio unless otherwise specified.
1 H NMR (proton nuclear magnetic resonance spectrum) was measured by Fourier transform NMR. For analysis, ACD / SpecManager (trade name) was used. Peaks with very gentle protons such as hydroxyl groups and amino groups are not described.
MS (mass spectrum) was measured by LC / MS (liquid chromatograph mass spectrometer). As the ionization method, ESI (ElectroSpray Ionization) method or APCI (Atomospheric Pressure Cheimcal Ionization) method was used. The data is the actual measurement (found). Usually, a molecular ion peak is observed, but in the case of a compound having a tert-butoxycarbonyl group (-Boc), a peak in which the tert-butoxycarbonyl group or tert-butyl group is eliminated as a fragment ion is observed. There is also. In the case of a compound having a hydroxyl group (—OH), a peak from which H 2 O is eliminated may be observed as a fragment ion. In the case of a salt, a free molecular ion peak or a fragment ion peak is usually observed.
The following abbreviations are used in the following examples.

Furthermore, an assay buffer containing XL665 conjugated Streptavidine, Eu3 + criptate conjugated GST antibody and 200 nM biotinylated SRC-1 (676-700) (final concentration 100 nM) was added, and reacted at room temperature for 2 hours. After excitation at 320 nm with a multiplate reader Envision (Perkin Elmer), fluorescence values at 620 nm and 665 nm were measured, and a 665/620 ratio value was calculated. The reverse agonist activity of the compound was calculated as a percentage, with 0% when no compound was added and 100% when XCT-790 was added at a final concentration of 10 μM.
