Mainly occurring in sexual nerve cells [J. Neurosci., 5, 2801-2808 (1985); Proc. Natl. Acad.
Sci. U. S. A., 82, 4531-4534 (1985)] や, もう一つの病理学的な特徴である老人斑の構成 成分である;3アミロイドによって神経細胞のグルタミン酸感受性が高まるとの報告もされて レヽる [Brain Res. , 533, 315-320 (1990); J.

Neurol. Neurosurg. Psychiatry, 54, 984-988 (1991)] and glutamate uptake disorder [N. Engl. J. Med ., 326,
1464-1468 (1992)] に基づくと考えられるグルタミン酸代謝異常が認められること [Ann. Neurol. 22, 575-579 (1987)] などから、 病態へのグルタミン酸の関与が報告されている。 し たがって、 グルタミン酸による神経細胞死を抑制することは、 これら疾患を始めとする神経系 の疾患の予防又は治療に有用であると考えられる。 本願発明の先行技術としては、 以下のものがある。 1464-1468 (1992)], and that glutamate metabolism is considered to be based [Ann.

Necrosis refers to death that occurs in a group of cells in a pathological condition, such as ischemia. That is, cell disruption and autolysis occur due to various external factors.
一方、 アポトーシスとは、 動物の健常組織における細胞のターンォ一バーや種々の臓器の発 生段階において不要な細胞を除去する際など、様々な原因により細胞が自発的に自分自身を殺 す機構を活性化して死んでいく状態である。  On the other hand, apoptosis is a mechanism by which cells spontaneously kill themselves for various reasons, such as when cells turn over in healthy tissues of animals and when unnecessary cells are removed during the developmental stages of various organs. It is in a state of being activated and dying.

グルタミン酸細胞毒性により起こる神経細胞死の抑制作用を、以下の方法を用いて評価した The following method was used to evaluate the inhibitory effect on neuronal cell death caused by glutamate cytotoxicity.
[赤池昭紀, 日薬理誌, 103, 198-201 (1994)]。 [Akinori Akaike, Journal of Pharmaceutical Sciences, 103, 198-201 (1994)].
本試験方法は、 神経細胞に化合物を加えた直後にグルタミン酸を添加し、 その細胞毒性が抑 制されているかどうか評価する方法である。  In this test method, glutamate is added immediately after the compound is added to nerve cells, and the cytotoxicity is evaluated to determine whether the cytotoxicity is suppressed.
すなわち、 胎生 18日齢の Wistar系ラットより脳を取り出し, 水冷下で大脳皮質を切り出 した。 この大脳皮質を DMEM培地 (岩城硝子社製) 中でピペッティングで細分化し、 ゥシ胎 児血清 (PAA社製) を添加して 1000 r pmで 5分間遠心した後、 上淸を捨て、 10%ゥ シ胎児血清を含む DMEM培地を加えて組織を分散させ、 70 /zmナイロンメッシュ (フアル コン社製) に通した。 血球計算盤で細胞数を計数した後、 ポリリジンでコーティングされた 9 6穴プレート (住友べ一クライ ト社製) に 3— 4 X 1 04細胞/穴の密度でまき、 37°C、 5% C02インキュベーターで培養した。 培養 1時間後に神経細胞培養液 (住友ベークライト社製) に交換した。 14日目にグルタミン酸による神経細胞死試験を実施した。 すなわち、 神経細胞 培養液を交換し、 本願発明の化合物、 0. 3 mMのグルタミン酸の順に添加した後、 24時間 培養した。 神経細胞死を起こした細胞から漏出した LDH量 (LDH遊離量) を LDH a s s a y k i t (プロメガ社) で測定した。 本願発明の化合物は DMS Oに溶解させ、 更に phosphate-buffered saline (PBS) で所定濃度に希釈して用いた。, 対照としては DMSO のみを同様に PB Sで希釈したもの (PBS群) を用いた。 That is, the brain was removed from an 18-day-old Wistar rat embryo, and the cerebral cortex was cut out under water cooling. The cerebral cortex was subdivided by pipetting in a DMEM medium (Iwaki Glass), centrifuged at 1000 rpm for 5 minutes at room temperature with fetal calf serum (PAA), and the supernatant was discarded. % ゥ DMEM medium containing fetal serum was added to disperse the tissue and passed through a 70 / zm nylon mesh (Falcon). After counting the cells using a hemocytometer, spread the cells on a 96-well polylysine-coated plate (Sumitomo Bei-Client) at a density of 3-4 x 10 4 cells / well at 37 ° C, 5 ° C. They were cultured in% C0 2 incubator. One hour after the culture, the cells were replaced with a nerve cell culture solution (Sumitomo Bakelite). On day 14, a neuronal death test with glutamate was performed. That is, the nerve cell culture solution was exchanged, and the compound of the present invention and 0.3 mM glutamic acid were added in this order, followed by culturing for 24 hours. The amount of LDH (LDH release) leaked from cells that had undergone nerve cell death was measured using an LDH assay kit (Promega). The compound of the present invention was dissolved in DMS O and further diluted to a predetermined concentration with phosphate-buffered saline (PBS) before use. As a control, DMSO alone diluted in PBS (PBS group) was also used.
本願発明の化合物の細胞死抑制率を以下の計算式により求めた。  The cell death inhibitory rate of the compound of the present invention was determined by the following formula.

本試験方法は、 神経細胞にグルタミン酸を 1 5分間添加した後、 グルタミン酸フリ一の状態 にして 7 5分後に化合物を加え、 神経細胞死が阻害されているかどうか評価する方法である。 すなわち、 生後 7— 8日齢の Wistar ラットをエーテル深麻酔後、 小脳を摘出した。 パパイ ン (9 U/ml)にて 3 7 °C、 1 5分処理によって分散させた細胞懸濁液を poly- L- lysine ( 25 μ g/ml ) でコートした培養プレー卜に 4-8 X 105 cells/cm2 の密度で播種して培養液 (10% ゥ シ胎仔血清, 20 mM KC1を含む MEM)中 3 7 °C、 5% C02/95% airで培養した。翌日に 20 M cytosine arabinofuranoside を含む等量の培養液を追加し、 必要に応じて培養 10 日目にグルコースを 添加した。 小脳顆粒細胞培養 11 - 12 Θ目にグルタミン酸による神経細胞死試験を実施した。 すなわち、 培養液をマグネシウム不含 Hanks' Balanced Salt Solutions (1. 26 mM CaCl2, 20 mM HEPESを含む) に交換し、 0. 3 mMグルタミン酸添加後 15分間室温インキュベーションし、 5%透 析済みゥシ胎仔血清、 20 mM HEPES, 25 mM KC1を含む MEMに培地を交換し、 その 75分後に 本願発明の化合物を添加した。 24時間培養後、神経細胞死を起こした細胞から遊離した Lactose Dehydrogenase量 (LDH遊離量)を測定した。本願発明の化合物は DMS0に溶解し、更に 0. 1%牛 血清アルブミン (BSA) を含む PBSで所定濃度に希釈して用いた。 対照としては DMS0のみを同 様に希釈したもの (PBS群) を用いた。 This test method is a method in which glutamate is added to nerve cells for 15 minutes, and then the compound is added 75 minutes later after free glutamate to evaluate whether nerve cell death is inhibited. That is, 7-8 day old Wistar rats were deeply anesthetized with ether and the cerebellum was removed. A cell suspension dispersed by treatment with papine (9 U / ml) at 37 ° C for 15 minutes was added to a culture plate coated with poly-L-lysine (25 μg / ml). culture was seeded at a density of X 10 5 cells / cm 2 and cultured (10% © shea calf serum, containing 20 mM KC1 MEM) in 3 7 ° C, 5% C0 2/95% air. The next day, an equal volume of culture solution containing 20 M cytosine arabinofuranoside was added, and glucose was added on the 10th day of culture as needed. Glutamate-induced neuronal cell death tests were performed on cerebellar granule cell cultures 11-12. That is, the culture solution was exchanged for Hanks' Balanced Salt Solutions (containing 1.26 mM CaCl 2 and 20 mM HEPES) containing no magnesium, and after adding 0.3 mM glutamic acid, the mixture was incubated at room temperature for 15 minutes and subjected to 5% permeation. The medium was replaced with MEM containing fetal serum, 20 mM HEPES, and 25 mM KC1, and the compound of the present invention was added 75 minutes later. After culturing for 24 hours, the amount of Lactose Dehydrogenase (LDH release) released from cells that had undergone nerve cell death was measured. The compound of the present invention was dissolved in DMS0 and further diluted to a predetermined concentration with PBS containing 0.1% bovine serum albumin (BSA) before use. As a control, DMS0 alone (PBS group) was similarly diluted.
本願発明の化合物の細胞死抑制率を以下の計算式により求めた。 細胞死抑制率 (%) = (グルタミン酸群の LDH遊離量一グルタミン酸及び本願発明の化合物群 の LDH遊離量) X 100/ (グルタミン酸群の LDH遊離量一 PBS群の LDH遊離量) The cell death inhibitory rate of the compound of the present invention was determined by the following formula.
