スフィンゴシン誘導体  Sphingosine derivative
技術分野 Technical field
本発明は、 中性スフィンゴミエリナ一ゼを阻害することにより各種医薬として 有用な新規スフィンゴシン誘導体に関する。 背景技術  The present invention relates to a novel sphingosine derivative useful as various medicines by inhibiting neutral sphingomyelinase. Background art
スフィンゴミエリナ一ゼは主に細胞膜に存在するスフィンゴ脂質の一つである スフインゴミエリンを基質として、 セラミドとホスホコリンに分解する酵素であ り、 その活性発現の至適 p Hから酸性タイプと中性タイプとに大別される。 酸性 タイプがリソゾームに局在するのに対し、 中性タイプは細胞膜あるいは細胞質に 存在するが、 両タイプ共にスフィンゴミエリンの代謝によるセラミドの生成に関 与していると考えられている。  Sphingomyelinase is an enzyme that decomposes into ceramide and phosphocholine using sphingomyelin, which is one of the sphingolipids mainly present in cell membranes, as a substrate. It is roughly divided into gender type. While the acidic type is localized in the lysosome, the neutral type is present in the cell membrane or cytoplasm, but both types are thought to be involved in the production of ceramide by sphingomyelin metabolism.
スフィンゴミエリナ一ゼにより生成されるセラミ ドは脂質セカンドメッセンジ ヤーとしてアポトーシス、 細胞増殖、 分化等の種々の細胞機能において重要な役 割を果たしており、この代謝産生経路はスフィンゴミエリン経路と呼ばれている。 スフインゴミエリナ一ゼは虚血、 T N F— «、 I L— 1 /3、 I F N—ァ、 1 , 2 5—ジヒドロキシビタミン D 3、 抗癌剤あるいは放射線等の各種ストレスによ り活性化されることから、 これらの化学的 ·物理的ストレスがその発症 ·進展の 原因である各種病態にスフィンゴミエリン経路が関与していることが考えられる 例えば、脳虚血時にはスフィンゴミエリン経路が活性化されるが、 脳神経細胞へ のスフィンゴミエリナーゼあるいはセラミドの添加はアポトーシスによる細胞死 を引き起こす。 また、 脳虚血時には T N F— αや I L一 1 /3の産生が亢進し、 神 経細胞死が誘発されるが、 T N F—ひの可溶化受容体や I L一 1 /3の受容体拮抗 剤は虚血による神経細胞死を抑制する。 The ceramide produced by sphingomyelinase plays an important role as a lipid second messenger in various cell functions such as apoptosis, cell proliferation and differentiation, and this metabolic pathway is called the sphingomyelin pathway. I have. Sphingomyelinase is activated by various stresses such as ischemia, TNF- «, IL-1 / 3, IFN-α, 1,25-dihydroxyvitamin D 3 , anticancer drugs and radiation. The sphingomyelin pathway may be involved in various pathological conditions that cause the onset and progression of these chemical and physical stresses.For example, the sphingomyelin pathway is activated during cerebral ischemia. Addition of sphingomyelinase or ceramide to cells causes cell death by apoptosis. In addition, during cerebral ischemia, production of TNF-α and IL-1 / 3 is increased and neuronal cell death is induced. However, TNF-solubilised receptor and IL-1 / 3 receptor antagonist Inhibits nerve cell death due to ischemia.
上記脳血管障害以外にも頭部外傷、 老人性痴呆、 アルツハイマー病、 パーキン ソン氏病等の脳神経変性疾患に広く T N F— αや I L一 1 /3の産生亢進が関与し ている。 非ィンスリン依存性糖尿病及び肥満では脂肪細胞での T N F - の産生が亢進 し、 インスリン抵抗性が誘導されるが、 これには T N F— αによるスフインゴミ エリン経路の活性化が関与している。 また、 I L— 1 i3はインスリン依存性糖尿 病の発症に関与するが、 セラミ ドは I L _ l βと同様の作用を発現する。 In addition to the above cerebrovascular disorders, increased production of TNF-α and IL-1 / 3 is widely involved in cerebral neurodegenerative diseases such as head trauma, senile dementia, Alzheimer's disease, and Parkinson's disease. In non-insulin-dependent diabetes mellitus and obesity, the production of TNF- in adipocytes is enhanced and insulin resistance is induced, and this involves the activation of the sufingomyelin pathway by TNF-α. In addition, IL-1 i3 is involved in the development of insulin-dependent diabetes mellitus, but ceramide exerts the same action as IL_lβ.
T N F - α及び I L一 1 /3は動脈硬化の発症 ·進展の過程にも関与する。 すな わち、 T N F— α及び I L— 1 /3は血管内皮細胞において接着因子の I C A M— 1を発現させ、 単球の血管内皮細胞への接着や内皮下への遊走を促進する。更に、 T N F— αはスフインゴミエリン経路の活性化を介して血管内皮細胞のアポトー シスを引き起こす。 また、 スフインゴミエリン経路の活性化は血管平滑筋での L D L凝集を促進し病変を形成すると共に、 血管平滑筋のアポトーシスを介してプ ラ一クを不安定化させる。  TNF-α and IL-1 / 3 are involved in the onset and progression of arteriosclerosis. In other words, TNF-α and IL-1 / 3 express the adhesion factor ICAM-1 in vascular endothelial cells, and promote adhesion of monocytes to vascular endothelial cells and migration into subendothelium. In addition, TNF-α causes apoptosis of vascular endothelial cells via activation of the sphingomyelin pathway. Activation of the sphingomyelin pathway also promotes LDL aggregation in vascular smooth muscle, forms lesions, and destabilizes plaques through apoptosis of vascular smooth muscle.
炎症免疫系細胞でのセラミ ドの生理活性は非常に多彩であり、 Τ細胞及び Β細 胞の分化 ·活性化、 各種サイ ト力イン産生、 アポトーシスの誘導、 炎症性プロス タグランジンの産生等を介して各種炎症性疾患及び免疫性疾患の発症 ·進展に深 く関与している。 また、 スフインゴミエリン経路の活性化には T N F— αや I L 一 1 ;3をはじめ非常に多くの化学的 ·物理的ストレスが関与することから、 これ らの病態には多くの細胞系及びシグナル経路が互いに複雑にクロストークしてい るものと考えられる。  The physiological activities of ceramides in inflammatory immune system cells are extremely diverse, including 分化 cell and Β cell differentiation and activation, production of various cytokins, induction of apoptosis, production of inflammatory prostaglandin, etc. It is deeply involved in the onset and progress of various inflammatory diseases and immunological diseases. In addition, the activation of the sphingomyelin pathway involves numerous chemical and physical stresses, including TNF-α and IL-11; 3. It is considered that the routes are crosstalking with each other in a complicated manner.
以上のことから、 スフインゴミエリナーゼに対する特異的な阻害剤は、 脳出血 や脳梗塞等の脳血管障害、 頭部外傷、 老人性痴呆、 アルツハイマー病やパーキン ソン氏病等の脳神経変性疾患、 糖尿病、 肥満、 動脈硬化、 炎症性疾患、 免疫性疾 患、 ガン、 腎疾患及び心疾患に対する予防薬、 治療薬として使用できる。  Based on the above, specific inhibitors for sphingomyelinase are cerebrovascular disorders such as cerebral hemorrhage and cerebral infarction, head trauma, senile dementia, neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease, and diabetes. It can be used as a preventive or remedy for obesity, arteriosclerosis, inflammatory disease, immune disease, cancer, kidney disease and heart disease.

(酵素調製)  (Enzyme preparation)
スフィンゴミエリナ—ゼの酵素源としてラット大脳を用い、 ミクロソーム画分 を以下の様に調製した。 10匹のウィスター雄性ラッ ト(4週齢)を断頭後、 全脳を 摘出した。 更に小脳を除去し、 予め 4°Cに冷却したバッファ一 A(10%ショ糖、 20 mM Hepes- KOH(pH7.4)、 20unit/mlァプロチニン、 O.lmM PMSF、 10/ g/mlロイべ プチン) 120mlを加え、 4 冷却下、 ホモジナイザーを用いて、 脳細胞を破砕した。 次に細胞破碎液を 4 冷却下、 600Xg、 10分間の遠心分離を行い、 その上清を更 に 12,000 Xgで 15分間の遠心分離を行った。 最後に得られた上清を 100,000 Xgで 60 分間の超遠心分離を行い、 その沈殿物をミクロゾーム画分とした。 この画分を更 に、 ノ ッファー B(10%ショ糖、 20mM Hepes- KOH(pH7.4)、 40unit/mlァプロチニン、 0.2mM PMSF、 20 g/mlロイぺプチン) 5 mlに再懸濁し、 — 80 で凍結保存し、 使 用時にバッファー C(20mM Hepes-KOH(pH7.4)-2mM MgC )で蛋白質濃度 2 mg/ mlになるように調整した。  Using rat cerebrum as an enzyme source of sphingomyelinase, a microsomal fraction was prepared as follows. After decapitation of 10 Wistar male rats (4 weeks old), the whole brain was removed. Further, the cerebellum was removed, and buffer A (10% sucrose, 20 mM Hepes-KOH (pH 7.4), 20 unit / ml aprotinin, O.lmM PMSF, 10 / g / ml (Putin) 120 ml, and the brain cells were crushed using a homogenizer under 4 cooling. Next, the cell lysate was centrifuged at 600 × g for 10 minutes under 4 cooling, and the supernatant was further centrifuged at 12,000 × g for 15 minutes. The obtained supernatant was ultracentrifuged at 100,000 Xg for 60 minutes, and the precipitate was used as a microsomal fraction. This fraction was further resuspended in 5 ml of Buffer B (10% sucrose, 20 mM Hepes-KOH (pH 7.4), 40 unit / ml aprotinin, 0.2 mM PMSF, 20 g / ml leptin). The solution was stored frozen at -80 and adjusted to a protein concentration of 2 mg / ml with buffer C (20 mM Hepes-KOH (pH 7.4) -2 mM MgC) at the time of use.
(基質溶液の調製)  (Preparation of substrate solution)
26.5mgのスフインゴミエリン (牛、 脳; シグマ社製)を 10w/v%トリ トン X 375 1 で溶解後、 バッファー C 14.6mlを添加してスフインゴミエリン溶液とした。 新た に、 400 1の N-メチル - 14 C-スフインゴミエリン(牛、 48mCi/mmol,25 Ci/ml; アマシャム社製)の溶媒を乾固し、 残査をエタノール 50 1に再度溶解し、 前述の 1 2mlのスフィンゴミエリン溶液を加え、 基質溶液とした。 After 26.5 mg of sphingomyelin (cattle, brain; manufactured by Sigma) was dissolved in 10 w / v% Triton X3751, 14.6 ml of buffer C was added to obtain a sphingomyelin solution. Fresh 400 1 of N- methyl - 14 C-staple Ingo myelin (bovine, 48mCi / mmol, 25 Ci / ml; Amersham) solvent dryness of, redissolved the residue in ethanol 50 1, The above-mentioned 12 ml of sphingomyelin solution was added to obtain a substrate solution.
(試験方法)  (Test method)
スフインゴミエリナーゼ反応は、 検体のジメチルスルホキシド溶液 10 1、 バッ ファー D(20mM Hepes-KOH(pH7.4)- 2 mM MgCl2、 0.08w/v%トリ トン X)70 l、 酵 素溶液 10 1、 基質溶液 10//1を混合後、 37°C、 3時間インキュベーションするこ とにより行った。 反応終了後、 クロ口ホルム: メタノール (2 : 1、 v/v)を 500 1加え て抽出操作を施し、 得られた水層より 150 1を 2 mlのアクアゾ一ル 2と混和して、 反応生成物である1 4 C -ホスホリルコリンを測定した。 スフィンゴミエリナ一ゼ 活性は酵素無添加の場合の測定値を差し引いた値として計算した。 The sphingomyelinase reaction was performed in the following manner: 10 1 dimethyl sulfoxide solution of sample, buffer D (20 mM Hepes-KOH (pH 7.4)-2 mM MgCl 2 , 70 l of 0.08 w / v% triton X), enzyme solution 10 1.After mixing the substrate solution 10 // 1, incubate at 37 ° C for 3 hours. And by After the completion of the reaction, black form: 500 1 of methanol (2: 1, v / v) was added to perform extraction operation. 150 1 was mixed with 2 ml of Aquazol 2 from the obtained aqueous layer, and the reaction was performed. The product, 14 C-phosphorylcholine, was measured. The sphingomyelinase activity was calculated as the value obtained by subtracting the measured value when no enzyme was added.
