Definitions
- the present invention relates to a compound having a glycine transporter inhibitory action.
- NMDA receptor which is one of glutamate receptors, exists on nerve cell membranes in the brain and is involved in various neurophysiological phenomena such as nerve plasticity, cognition, attention, and memory.
- the NMDA receptor has a plurality of 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).
- Glycine transporter 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 cerebral cortex, hippocampus and thalamus, etc., and is 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, tremor, pain, Parkinson's disease, attention deficit / hyperactivity disorder, bipolar disorder, eating disorder, and sleep A relationship with a disease such as a disorder has been reported (Non-Patent Documents 2 to 4).
- Patent Documents 1 and 2 Compounds having GlyT1 inhibitory activity and having an imidazolidin-2-one structure have been reported in the following documents (Patent Documents 1 and 2).
- Patent Documents 1 and 2 a phenyl group is bonded to one ring nitrogen atom of imidazolidine through an amide or carbonyl, and the other ring nitrogen atom of imidazolidine is bonded to A compound in which a phenyl group is bonded, and the imidazolidinone ring carbon atom is a spiro carbon atom.
- the present invention relates to schizophrenia, Alzheimer's disease, cognitive dysfunction, dementia, anxiety disorder (general anxiety disorder, panic disorder, obsessive compulsive disorder, social anxiety disorder, post-traumatic stress disorder, specific Prevention, depression, drug dependence, convulsions, tremors, pain, Parkinson's disease, attention deficit / hyperactivity disorder, bipolar disorder, eating disorders, or sleep disorders Alternatively, it is an object to provide a novel compound useful for treatment or a pharmaceutically acceptable salt thereof.
- anxiety disorder general anxiety disorder, panic disorder, obsessive compulsive disorder, social anxiety disorder, post-traumatic stress disorder, specific Prevention, depression, drug dependence, convulsions, tremors, pain, Parkinson's disease, attention deficit / hyperactivity disorder, bipolar disorder, eating disorders, or sleep disorders
- the present inventors have obtained a compound represented by the following formula, which contains a nitrogen-containing aromatic group on one ring nitrogen atom of imidazolidine.
- the inventors have found that a compound having a ring group bonded thereto and an imidazolidinone ring carbon atom not being a spiro carbon atom is an excellent GlyT1 inhibitor, and has completed the present invention.

試験例1 [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2.0×104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、被検物質を10分間前処置した。その後、被検物質および[3H]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10-9~10-5M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。
