Definitions
- the present invention relates to a novel pyrazolopyrimidine compound having an excellent HIF-PHD inhibitory action and useful as a medicine.
- Anemia refers to a state in which the amount of red blood cells and hemoglobin in the blood has decreased, and often exhibits symptoms such as fatigue, shortness of breath, palpitation, dizziness, and facial pallor.
- the cause is decreased production of red blood cells (ineffective hematopoiesis that hematopoietic cells cannot produce normal red blood cells, decrease in hematopoietic cells, decrease in hematopoietic factors (such as erythropoietin)), increased destruction (hemolysis), increased loss (bleeding) It is divided roughly.
- Erythropoietin is a hematopoietic factor that is secreted from the kidney and acts on erythroid stem cells of the bone marrow to promote erythrocyte production. It is known that in patients with impaired renal function such as chronic renal failure, production of erythrocytes is reduced due to a decrease in EPO production from the kidney, resulting in anemia (renal anemia).
- a treatment method for renal anemia replacement therapy with recombinant human EPO can be mentioned.
- the treatment method has greatly contributed to improvement of QOL (Quality of life) such as improvement of symptoms associated with anemia and avoidance of regular blood transfusion.
- QOL Quality of life
- the recombinant human EPO is a biologic and expensive medical care, is inconvenient because it is an injection, and has antigenicity.
- hypoxia-inducible factor As a typical factor that promotes the transcription of EPO, hypoxia-inducible factor (HIF) can be mentioned.
- HIF is a major factor involved in gene expression induction by low oxygen concentration, and is a heterodimer composed of ⁇ and ⁇ subunits. Under normal oxygen concentration, HIF is hydrated with von Hippel-Lindau (VHL) protein by hydroxylating the ⁇ subunit proline by hypoxia-inducible factor-prolyl hydroxylase (HIF-PHD). Combined and ubiquitinated.
- VHL von Hippel-Lindau
- HIF-PHD hypoxia-inducible factor-prolyl hydroxylase
- HIF-PHD hypoxia-inducible factor-prolyl hydroxylase
- HIF-PHD has three isoforms, HIF-PHD1, HIF-PHD2, and HIF-PHD3. Under normal oxygen concentration, HIF-PHD2 is responsible for HIF proline hydroxylation. On the other hand, HIF-PHD1 and HIF-PHD3 are also involved in proline hydroxylation of HIF depending on cell types and tissues. That is, the production of EPO can be increased by inhibiting the proline hydroxylation activity of HIF-PHD and preventing and stabilizing the ubiquitination of HIF. Therefore, it is considered that an inhibitor of HIF-PHD can be a therapeutic drug for anemia.
- HIF-PHD HIF-PHD
- Other diseases that can be expected to be improved by inhibiting HIF-PHD and stabilizing HIF include ischemic heart disease (angina, myocardial infarction, etc.), ischemic cerebrovascular disorders (cerebral infarction, cerebral embolism, Transient cerebral ischemic attack), chronic renal failure (ischemic nephropathy, tubulointerstitial disorder, etc.), diabetic complications (diabetic wound, etc.), cognitive impairment (dementia, Alzheimer's disease, Parkinson's disease, Huntington's disease etc.).
- ischemic heart disease angina, myocardial infarction, etc.
- ischemic cerebrovascular disorders Cerebral infarction, cerebral embolism, Transient cerebral ischemic attack
- chronic renal failure ischemic nephropathy, tubulointerstitial disorder, etc.
- diabetic complications diabetic wound, etc.
- cognitive impairment disementia, Alzheimer's disease, Parkinson's disease, Huntington

実験例1 HIF-PHD阻害試験
被検化合物
上記実施例に記載の化合物を、HIF-PHD阻害試験に用いた。
試験方法
ヒトHIF-PHD2およびヒトHIF-PHD3に対する被検化合物の阻害作用を次の方法により決定した。
20 mmol/L トリス(ヒドロキシメチル)アミノメタン-塩酸緩衝液 (pH8.0), 120 mmol/L 塩化ナトリウム, 3.33 mmol/L アスコルビン酸, 2-オキソグルタル酸(ヒトHIF-PHD2の場合は3.33 μmol/L、ヒトHIF-PHD3の場合は166 μmol/L), 166 μmol/L 塩化鉄(II), 2.67 ug/mL ヒトVHL-Enlondin B-Enlondin C complex (ヒトVBC complex, CrystalGenomics社製), 6.67 nmol/L 合成FAM-HIF-2αペプチド(FAM-ACA-ELDLETLAPYIPMDGEDFQL)を含む酵素反応溶液を調製し,15 μLを96 wellハーフエリアプレートに分注した.同プレートに被検化合物のジメチルスルホキシド溶液(目的とする終濃度の5倍濃度)を5 μLずつ加え,プレートミキサーで混合し,enVision(Perkin Elmer社製)を用いて蛍光偏光値を測定した(ex. 480 nm,em. 535 nm).次に、HIF-PHD2またはHIF-PHD3(いずれもCrystalGenomics社製)を含む酵素溶液を5 μLずつ加えてプレートミキサーで混合し,20-40分後にenVisionを用いて蛍光偏光値を測定した(ex. 480 nm,em. 535 nm).酵素添加後の蛍光偏光値(mP値)から酵素添加前の蛍光偏光値を引いた値を酵素活性値とした.酵素のみのwellにおける活性値を100%,酵素を含まないwellの活性値を0%として各wellの活性値を百分率に換算して検体による酵素活性の阻害率とし,得られた結果をGraph Pad Prism(Graph Pad Software社製)にてS字曲線に回帰させ,IC50値を計算した.
FAM: 5'-フルオレセインアミド(5'-fluorescein amide)
ACA: アミノカプロン酸(aminocaproic acid)
被検化合物
上記実施例に記載の化合物を、EPO産生試験に用いた。
試験方法
Hep3B細胞を用いて化合物のEPO産生促進作用を次のように決定した。
細胞は,96 wellプレートに40000 cells/wellとなるよう播種し、10% ウシ胎児血清(FBS)を含むMEM培地で、37℃、5%CO2の条件下で一晩培養した。翌日、0.5% FBSを含むMEMに培地交換し、被検化合物を添加した。被検化合物は、ジメチルスルホキシドに溶解し、細胞への添加はジメチルスルホキシド終濃度が0.1%となるように調製した。さらに48時間培養した後、培養上清を回収し、上清中に含まれるEPOをELISAキット(EPO ELISA Kit 11-693-417-001, Roche社製)を用いて測定した。測定結果は,3μmol/Lの被検化合物添加時のEPO産生量を、無刺激時(コントロール)のEPO産生量に対する相対値として算出したEPO産生誘導率(倍)で表示した。
EPO産生誘導率(倍)=(被検化合物添加時のEPO産生量)/(コントロールのEPO産生量)
