Description

本発明は、グリシントランスポーター阻害作用を有する化合物に関する。   The present invention relates to a compound having a glycine transporter inhibitory action.

グルタミン酸受容体の一つであるNMDA受容体は脳内の神経細胞膜上に存在しており、神経の可塑性、認知、注意、記憶など様々な神経生理学的な現象に関わっている。NMDA受容体には複数のアロステリック結合部位が存在し、グリシン結合部位もその1つである(NMDA受容体複合体グリシン結合部位)。NMDA受容体複合体グリシン結合部位はNMDA受容体の活性化に関与していることが報告されている(非特許文献1)。   The NMDA receptor, which is one of glutamate receptors, exists on the nerve cell membrane in the brain and is involved in various neurophysiological phenomena such as nerve plasticity, cognition, attention, and memory. The NMDA receptor has multiple allosteric binding sites, one of which is the glycine binding site (NMDA receptor complex glycine binding site). It has been reported that the NMDA receptor complex glycine binding site is involved in the activation of the NMDA receptor (Non-patent Document 1).

グリシン作動性神経のシナプス前終末に活動電位が到達するとシナプス間隙へのグリシンの放出が開始される。放出されたグリシンはシナプス後部の受容体等と結合した後、トランスポーターによりシナプス間隙から取り除かれる。このことよりグリシンのトランスポーターは細胞外液にあるグリシン量を調節することでNMDA受容体の機能を調節していると考えられている。   When the action potential reaches the presynaptic terminal of the glycinergic nerve, release of glycine into the synaptic cleft is started. The released glycine is removed from the synaptic cleft by the transporter after binding to a receptor or the like at the postsynaptic part. This suggests that the glycine transporter regulates the function of the NMDA receptor by regulating the amount of glycine in the extracellular fluid.

グリシントランスポーター(GlyT)は細胞外グリシンの細胞内への再取り込みに関わっているタンパクであり、現在までにGlyT1及びGlyT2の二つのサブタイプの存在が明らかとなっている。GlyT1は主に大脳皮質、海馬及び視床等に発現しており、統合失調症、アルツハイマー病、認知機能障害、認知症、不安障害(全般性不安障害、パニック障害、強迫性障害、社会不安障害、外傷後ストレス障害、特定の恐怖症、急性ストレス障害等)、うつ病、薬物依存、痙攣、振戦、及び睡眠障害等の疾患との関連が報告されている(非特許文献2〜4)。   Glycine transporter (GlyT) is a protein involved in the reuptake of extracellular glycine into cells, and the existence of two subtypes, GlyT1 and GlyT2, has been clarified so far. GlyT1 is mainly expressed in the cerebral cortex, hippocampus and thalamus, etc., and includes schizophrenia, Alzheimer's disease, cognitive dysfunction, dementia, anxiety disorder (generalized anxiety disorder, panic disorder, obsessive compulsive disorder, social anxiety disorder, Post-traumatic stress disorder, specific phobia, acute stress disorder, etc.), depression, drug dependence, convulsions, tremors, and sleep disorders have been reported (Non-Patent Documents 2 to 4).

GlyT1阻害作用を有する化合物としてはピペリジン誘導体及びピロリジン誘導体が報告されている(特許文献1〜8)。

試験例 [グリシン取り込み阻害実験]
グリシン取り込み実験はNeuron, 8, 927-935, 1992に掲載された方法に従って行った。ヒト1型グリシントランスポーター(GlyT1)を発現した神経膠腫であるT98G細胞を用いた。T98G細胞を96ウェルプレートに2.0×10個/ウェルにて播種し、炭酸ガスインキュベーター内にて一晩培養した。被検物質は100%DMSO溶液に溶解したのち、150mM塩化ナトリウム、1mM塩化カルシウム、5mM塩化カリウム、1mM塩化マグネシウム、10mMグルコースおよび0.2%ウシ血清アルブミンを含む10mMHEPES緩衝液(pH7.4)に溶解させた。細胞培養用培地を除去した後、被検物質および[H]グリシン(最終濃度 250nM)を細胞に添加し、室温にて15分間反応させた。反応終了後、マニーホールドにて細胞外液を吸引し、細胞外に存在する余分な標識グリシンを除去したのち、0.5Mの水酸化ナトリウム水溶液にて細胞を溶解した。細胞内に存在するグリシン量は、細胞溶解液中の放射活性を液体シンチレーションカウンターで測定することにより求めた。10μMのALX5407存在下におけるグリシン取り込み量を非特異的取り込みとし、10μMのALX5407非存在下の総取り込み量から非特異的取り込み量を差し引いたものを特異的取り込み量とした。また、被検物質の10−10〜10−6濃度での抑制曲線からグリシン取り込み阻害活性(IC50値)を算出した。
Test example [Glycine uptake inhibition experiment]
The glycine uptake experiment was performed according to the method published in Neuron, 8, 927-935, 1992. T98G cells that are gliomas expressing human type 1 glycine transporter (GlyT1) were used. T98G cells were seeded in a 96-well plate at 2.0 × 10 4 cells / well, and cultured overnight in a carbon dioxide incubator. A test substance is dissolved in a 100% DMSO solution, and then dissolved in 10 mM HEPES buffer (pH 7.4) containing 150 mM sodium chloride, 1 mM calcium chloride, 5 mM potassium chloride, 1 mM magnesium chloride, 10 mM glucose, and 0.2% bovine serum albumin. Dissolved. After removing the cell culture medium, a test substance and [ 3 H] glycine (final concentration 250 nM) were added to the cells and allowed to react at room temperature for 15 minutes. After completion of the reaction, the extracellular fluid was aspirated with a manifold, the excess labeled glycine present outside the cells was removed, and then the cells were lysed with a 0.5 M aqueous sodium hydroxide solution. The amount of glycine present in the cells was determined by measuring the radioactivity in the cell lysate with a liquid scintillation counter. The glycine uptake in the presence of 10 μM ALX5407 was defined as nonspecific uptake, and the total uptake in the absence of 10 μM ALX5407 minus the nonspecific uptake was defined as the specific uptake. Moreover, the glycine uptake inhibitory activity (IC 50 value) was calculated from the inhibition curve at 10 −10 to 10 −6 concentration of the test substance.
