Definitions
- the present invention relates to a condensed piperidine compound having an erythropoietin production promoting action and / or a hemoglobin production promoting action. More specifically, the present invention relates to a novel condensed piperidine compound useful for the prevention and / or treatment of diseases caused by decreased erythropoietin production, such as anemia.
- Erythropoietin is a glycoprotein hormone involved in the maturation and differentiation of erythroid progenitor cells into mature erythrocytes, and is a naturally occurring monomeric polypeptide consisting of 165 amino acids (Non-patent Document 1). ).
- EPO Human EPO is essential for the growth and differentiation of red blood cells, and is useful for the treatment of blood diseases characterized by a decrease in red blood cell production. Clinically, EPO is found in patients with chronic renal failure (CRF) who are treated for anemia, self-contained blood and premature infant anemia (Non-Patent Documents 2-4), AIDS, and cancer patients undergoing chemotherapy. (Non-patent Document 5). EPO has also been shown to be effective in chronic anemia.
- EPO is produced mainly in the kidney in adults, but is also produced in astrocytes and neurons in the central nervous system, and EPO and EPO receptors are expressed in capillaries at the brain-periphery boundary.
- systemic administration of EPO has been reported to cross the blood brain barrier and reduce neuronal cell loss in response to brain and spinal cord ischemia, mechanical trauma, epilepsy, excitotoxins and neuroinflammation. (Non-Patent Documents 6 to 10).
- Non-patent Documents 11 and 12 In the therapy using a protein such as EPO, in order to maintain a therapeutically effective concentration of the compound in the circulation and a short plasma half-life due to being susceptible to protease degradation (Non-patent Documents 11 and 12) There are problems such as having to make internal injections frequently.
- there is subcutaneous injection as an administration route instead of intravenous injection but since the absorption from the administration site is slow, there is a sustained release effect, but the plasma concentration is significantly lower than that of intravenous injection. Therefore, in order to obtain the same therapeutic effect, the same number of injections as in the case of intravenous injection must be performed, which is a burden on the patient.
- human serum EPO is a glycoprotein, and the structure of the sugar chain bound to the surface of EPO is complex, and its glycosylation is extensive and diverse. However, human serum EPO cannot be produced with good reproducibility.
- Non-patent Document 13 a hypoxia-inducible factor (HIF) that is a transcription factor. That is, under normal atmospheric conditions, the HIF subunit (HIF-1 ⁇ ) in which the proline residue is hydroxylated by the 2-oxoglutarate dioxygenase enzyme is degraded by the ubiquitin-proteasome system, and the production of EPO is not promoted.
- HIF hypoxia-inducible factor
- HIF-1 ⁇ moves from the cytoplasm into the nucleus and dimerizes with HIF-1 ⁇ . It forms a body and binds to a hypoxia responsive element (HRE) sequence of the EPO gene to promote transcription and promote EPO production.
- HRE hypoxia responsive element
- Enzyme inhibitors for HIF prolyl hydroxylase such as 2-oxoglutarate dioxygenase enzyme utilizing such an EPO production mechanism have been reported as EPO production promoters (Patent Documents 1 to 4).
- genes whose expression is controlled by HIF include not only genes encoding EPO but also genes encoding vascular endothelial growth factor (VEGF). It has also been reported that VEGF has an angiogenesis-promoting action and can cause malignant tumors to deteriorate through this function (Non-Patent Documents 14 and 15). In addition, since anemia is also caused by cancer chemotherapy, and an anemia treatment drug may be administered to a cancer patient receiving such chemotherapy (Non-patent Document 5), VEGF worsens cancer. Such a risk is included in a compound having an inhibitory activity on HIF prolyl hydroxylase activity that may also promote the expression of
- EPO The production of EPO is controlled by a promoter located on the 5 'side of EPO and an enhancer located on the 3' side, and HIF is considered to bind to the HRE sequence in the enhancer and promote the production of EPO.
- GATA-2, NF ⁇ B, and the like are also considered to control EPO production (Non-patent Documents 16 and 17), and it is considered that EPO production promotion can be achieved by an action mechanism other than inhibition of HIF prolyl hydroxylase enzyme activity. Therefore, a compound having an EPO production promoting action independent of inhibition of HIF prolyl hydroxylase enzyme activity is considered useful in the treatment of anemia.
- EPO promotes proliferation and maturation of erythroid progenitor cells, but a compound having an action of promoting maturation / differentiation of erythroid progenitor cells without involving production of EPO is also a therapeutic agent for anemia.
- Compounds that have an activity to enhance blood cell proliferation promoting action of EPO and compounds that have an inhibitory action on hematopoietic cell phosphatase that catalyzes dephosphorylation, which is one of the important control mechanisms of EPO signaling, have been reported. (Patent Documents 5 to 7), however, the activity is not always sufficient.
- Non-patent Document 18 synthetic peptides and hematides that act on the EPO receptor have been reported (Non-patent Document 18), a high dose is required for the expression of activity equivalent to EPO, and it is not suitable for oral administration. There is.
- an orally administrable low molecular weight anemia treatment agent that has both an EPO production promoting action and a hemoglobin production promoting action is considered to be useful in the future treatment of anemia.
- those having a condensed piperidine skeleton related to the present invention include CRTH2 inhibitors effective for inflammatory diseases (Patent Documents 8 and 9), G protein-coupled receptor inhibitors effective for heart failure and the like (Patent Document 10). ), Cholesterol ester transfer protein inhibitors effective for arteriosclerosis and the like (Patent Documents 11 and 12) are disclosed, but any of these documents relates to EPO production promoting action, moglobin production promoting action, and anemia treatment of these compounds.

<材料と方法>
ヒト肝臓癌由来である細胞株HepG2を10%ウシ胎児血清を含む最少必須培地(MEM)(シグマ)を用いて48穴プレートの各穴に5×104細胞ずつ播種した。翌日、培地をフェノールレッドを含まない10%ウシ胎児血清含有ダルベッコ改変イーグル培地(DMEM(シグマ))に交換し、DMSOに溶解した被検化合物を最終濃度3μM又は10μMとなるように添加し、培地量を1穴あたり400μlとした。酸素濃度を4%としたCO2インキュベーターで48時間インキュベート後、培養上清を回収した。培養上清中のEPO濃度はEPO ELISAキット(ロシュ・ダイアグノスティックス)を用いて直ちに測定した。方法は取扱説明書に準じた。
被検化合物を最終濃度3μM添加することにより、最大で416%(化合物1)のEPO産生促進が認められた(表3参照)。このことから、これらの化合物にはEPO産生促進作用があることが明らかとなり、貧血治療剤として有用であることがわかった。
<材料と方法>
ヒト前赤芽球細胞株であるK562(ATCCより入手)を完全培地(10%ウシ胎児血清を含むRPMI-1640培地)を用いて、24穴プレートの各穴に1×105細胞/1mLずつ播種し、被検化合物を最終濃度6μMとなるように添加後、CO2インキュベーター(37℃、5%CO2)で3日間培養した。培地交換を行い、さらに3日間培養した。細胞を集め、カウントした後、細胞数を3×105個に揃え、ポルフィリン環の蛍光を測定することにより細胞内に産生されたヘモグロビン量を求めた。すなわち、遠心して集めた細胞を2Mシュウ酸500μLに懸濁し、30分間加熱沸騰させ、冷却後、蛍光強度を蛍光マイクロプレートリーダー(Spectra MAX GeminiEM;モレキュラーデバイス社)を用いて測定した(Em:400nm Ex:603nm)。化合物を添加しない未刺激状態でのヘモグロビン量を100%とし、各化合物により産生誘導されたヘモグロビン量(% of control)を求めた。その結果を表5に示す。
6μMの被検化合物を添加することにより、最大で520%(化合物10)のヘモグロビン産生促進が認められた(表5参照)。従って、当該化合物には前赤芽球から赤血球への成熟を促進させ、ヘモグロビンの産生を促進させる作用があることが判明した。
