Definitions
- the present invention relates to the prevention and / or treatment of piperazine compounds or salts thereof, and pharmaceutical compositions containing these as active ingredients, particularly allergic diseases, inflammatory diseases, muscle degenerative diseases, etc. due to hematopoietic prostaglandin D synthase inhibitory action. It relates to the agent.
- Prostaglandin D2 is an inflammatory mediator that is produced and released most in mast cells activated by binding of a complex of an antigen and immunoglobulin E (Non-patent Document 1) and allergy. It is thought to play an important role in the onset of symptoms. PGD2 has been detected at high concentrations in bronchoalveolar lavage fluid of asthmatic patients (Non-patent Document 2), and it has been reported that airway contraction is observed by inhalation of PGD2 compared to healthy individuals (Non-patent Document) 3).
- PGD2 the synthase that produces PGD2 is called prostaglandin D synthase, and there are two known types of hematopoietic enzymes and lipocalin-type enzymes. Since PGD2 is involved in the onset and exacerbation factors of various diseases including allergic diseases and in vivo regulation mechanisms, improving production abnormalities is extremely effective as a drug for various diseases. It is thought that it is.
- H-PGDS hematopoietic prostaglandin D synthase
- Non-patent Document 4 Asthma, rhinosinusitis, dermatitis, chronic obstruction due to high expression of H-PGDS in mast cells and inflammatory cells in the nasal mucosa of patients with allergic rhinitis or in the nasal fin of patients with chronic sinusitis
- PGD2 derived from H-PGDS plays an important role in the onset and exacerbation of allergic diseases such as pulmonary diseases.
- H-PGDS expression in the necrotic part has been confirmed (Non-patent Document 5).
- PGD2 derived from hematopoietic enzyme is also involved in diseases with tissue damage such as muscular dystrophy, amyotrophic lateral sclerosis, multiple sclerosis, irritable colitis, rheumatoid arthritis, chronic obstructive arterial disease, etc. (Non-patent Document 6).
- inhibitors of H-PGDS are useful for the prevention and prevention of allergic diseases or inflammatory diseases involving PGD2 produced by hematopoietic enzymes or metabolites thereof, as well as diseases such as myonecrosis and traumatic brain injury. It can be expected to be a useful drug as a therapeutic drug.
- H-PGDS inhibitors for example, Patent Documents 1 and 2
- H-PGDS inhibitors having a structure similar to the compound of the present invention are also disclosed (Patent Document 3).
- Piperazine compounds have been extensively studied as useful compounds for pharmaceuticals and the like in addition to H-PGDS inhibitors.
- Patent Document 4 describes a piperazine compound having a furylcarbonylpiperazine structure as an inhibitor of hedgehog signaling.
- Patent Document 5 describes a wide range of piperazine compounds as compounds that interact with potassium channels.
- Patent Document 6 describes a urea compound characterized by having a piperazine ring as a compound useful for diseases involving fatty acid amide hydrolase.
- the main problem of the present invention is to provide a novel compound having a high effect of inhibiting prostaglandin D synthase, particularly H-PGDS, at a low dose.
- the incidental problem of the present invention is to provide a highly safe pharmaceutical with few side effects and effective in the prevention and treatment of PGD2 derived from the enzyme or its metabolite-mediated diseases based on the H-PGDS inhibitory action. It is to provide.
- the present invention provides the following piperazine compounds, pharmaceutical compositions, prostaglandin D synthase inhibitors, prostaglandin D2 or prophylactic and / or therapeutic agents for diseases involving metabolites thereof.

国際公開WO2007-007778号公報の方法に準じて合成した。
Urade、Y.らの方法(J. Biol. Chem. 262, 3820-3825 (1987))に準拠して実施した。すなわち、反応液(49μL);100mM Tris-HCl (pH 8.0)、1mM 還元型グルタチオン、 0.1mg/mLγ-グロブリン、ヒトH-PGDS(適量)及び化合物(終濃度:0.01~100μM)を25℃で5分間プレインキュベーションした。なお、溶媒対照群(Control群)には終濃度1% DMSO溶液を添加した。次いで、[14C]プロスタグランジンH2(終濃度:10μM)1μLを添加することで反応を開始した。反応開始1分後に-20℃の反応停止液(ジエチルエーテル/メタノール/1M クエン酸(30/4/1) 250μLを添加することで反応を停止させた。反応停止後の上層部(有機溶媒相)の50μLをTLCプレートにアプライし、-20℃で45分間展開した(展開剤:ジエチルエーテル/メタノール/酢酸(90/2/1))。TLCプレートを乾燥後、イメージングプレートに1時間から一昼夜露光し、プロスタグランジンD2(PGD2)に相当する放射活性をイメージアナライザー(富士フイルム)で解析した。PGD2のバンドの1レーン当たりに占める割合(%)を算出し、各実験で設けたControl群に対する実施例化合物0.1μMにおける抑制率(%)、及びH-PGDSに対する50%阻害濃度(IC50値、nM)を算出し、この結果を第1表に示した。
抗原誘発鼻炎モルモットの鼻腔内PGD2産生抑制作用
5週齢雄性Std:Hartley系モルモットに1mg/mLの卵白アルブミン生理食塩溶液1mL/bodyを背部皮下注射して能動感作した(初回感作)。初回感作1週間後及び2週間後、マイクロピペットを用いて10mg/mL卵白アルブミン生理食塩溶液を20μLずつ両側の鼻腔内に投与した(点鼻感作)。初回感作3週間後、マイクロピペットを用いて10mg/mL卵白アルブミン生理食塩溶液を20μLずつ両側の鼻腔内に投与して鼻炎反応を惹起した。
鼻腔洗浄液中PGD2低下率(%)=
{(対照群のPGD2濃度 - 化合物投与群のPGD2濃度)÷(対照群のPGD2濃度 - 正常群のPGD2濃度)}×100
抗原誘発鼻炎モルモットの好酸球浸潤抑制作用
5週齢雄性Std:Hartley系モルモットに1mg/mLの卵白アルブミン生理食塩溶液1mL/bodyを背部皮下注射して能動感作した(初回感作)。初回感作1週間後及び2週間後、マイクロピペットを用いて10mg/mL卵白アルブミン生理食塩溶液を20μLずつ両側の鼻腔内に投与した(点鼻感作)。初回感作3週間後、マイクロピペットを用いて10mg/mL卵白アルブミン生理食塩溶液を20μLずつ両側の鼻腔内に投与して鼻炎反応を惹起した。
好酸球数(×105 cells)=
(好酸球のカウント数 ÷ 総数のカウント数(300))× 総細胞数
抑制率(%)=
{(対照群の好酸球数 - 化合物投与群の好酸球数)÷(対照群の好酸球数 - 正常群の好酸球数)}×100
マウス前肢握力試験
病態群として4週齢雄性C57BL/10-mdx(mdx)マウスを、正常群として4週齢雄性C57BL/10Sn(wild)を試験に供した。入荷後馴化期間を設けて、5週齢時に各個体の前値を測定し、各群に10匹の個体を割り付けた。その翌日より、供試化合物(30mg/kg)を1日1回、4週間連続経口投与した。対照群の動物へは媒体のみを経口投与した。投与開始から4週間後に前肢握力を測定した。評価指標は、小動物握力測定装置(GPM-100M、Melquest社)を用いて測定した5回の前肢握力測定値(kg)の平均値を体重(kg)で除した値を用いた(参考文献:Muscle Nerve. ,35, 43-48(2007))。
