Definitions
- the present invention relates to a pharmaceutical composition containing a triazole derivative useful as an inhibitor of glycine transporter activity as an active ingredient, and a novel triazole derivative having an action as an inhibitor of glycine transporter activity.
- Glycine is known to be an excitatory and inhibitory neurotransmitter in the central and peripheral nervous systems. These functions are mediated by two different receptors, and it is thought that different glycine transporters are involved in the regulation of neurotransmission through these receptors. Its function as an inhibitory neurotransmitter is mainly through strychnine-sensitive glycine receptors present in the spinal cord and brainstem. On the other hand, its function as an excitatory neurotransmitter is mediated by the N-methyl-D-aspartate (NMDA) receptor, known as the glutamate receptor subtype. Glycine is known as a co-agonist at the NMDA receptor (Johnson, J. W.
- NMDA receptors are widely distributed in the brain, especially in the cerebral cortex and hippocampus.
- the neurotransmitter transporter plays a major role in regulating neurotransmitter concentration in the ricinus gap by taking up the neurotransmitter into cells. In addition, it is thought that by incorporating it into presynaptic terminals, it contributes to reuse. Modulation of the neurotransmitter transporter function is considered to be useful for the treatment of various disease states caused by abnormal neurological functions by regulating the concentration of neurotransmitter in the synaptic cleft.
- GLYT The glycine transporter
- GLYT1 is expressed at high density in the spinal cord, brain stem, cerebellum, diencephalon and retina, and is expressed at low density in the olfactory bulb and cerebral hemisphere, and is thought to regulate NMDA receptor function (Smith, KE. , et al., Cloning and expression of a glycine transporter reveal colocalizaion with N MDA receptors, Neuron, 8, 927-35, 1992, Guastella, J. et al., Cloning, expression, then localization of a rat brain high- Natl.Acad.Sci., 89, 7189-93, 1992, and Bergeron, R.
- GLYT2 the expression of GLYT2 is restricted to the spinal cord, brain stem and cerebellum (Goebel, DJ, Quantitative gene expression of two types of glycine transporter in the rat central nervous system, Mol. Brain Res., 40, 139). -42, 1996, Zafra.F., Et al., Glycine transporters are differentially expressed among CNS cells, J. Neurosci., 15, 3952-69, 1995), indicating that GLYT2 functions as a strychnine-sensitive glycine receptor. It is thought to be involved in regulation.
- GLYT2 Inhibition of GLYT2 is thought to cause a decrease in pain transmission in the spinal cord through potentiation of strychnine-sensitive glycine receptor function (Yaksh, T ⁇ ., Behavioral and aut onomic correlates of the tactile evoked allodynia produced by spinal glycine inhibition : Effects of modulatory receptor systems and excitatory amino acid antagonists, Pain, 37, 111-123, 1989). Furthermore, enhancement of spinal strychnine-sensitive glycine receptor function is considered to be useful for treatment of muscle contraction disorders such as spasm (twitch), myoclonus, and epilepsy (Truong, DD et. Al., Glycine involvement in DDT-induced myoclonus. Movement Disorders.
- spastic mouse FASEB J. 4, 2767-2774, 1990.
- Spasm has been associated with neurological disorders and injuries such as epilepsy, cerebrovascular disorders, head trauma, multiple sclerosis, spinal cord injury, and dystonia.
- NMDA receptors are known to be associated with various disease states. It has been suggested that NMDA receptor hypofunction is associated with schizophrenia (Javitt, DC and Zukin, SR Recent advances in the phencyclidine model of schizophrenia, American Journal of Psychiatry, 148, 1301-8, 19991) In schizophrenic patients, improvement of negative symptoms by glycine overdose has been reported (Heresco-Levy U. et.al., Double-blind, placebo-controlled, crossover trial of glycine adjuvant therapy for treatment-resistant. schizophrenia, Br J Psychiatry, 169, 610-7, 1996).
- LTP long-term potentiation
- NMDA receptor activation is involved in the formation of long-term potentiation (LTP), which is considered to be a neuronal model of memory and learning (Collingridge, G ⁇ . And Bliss, D.V. , NMDA receptors-their role in long-term potentiation. Trends. Neurosci., 10, 288-93, 1987), and amnesic activity in animals by administration of NMDA receptor antagonists (Morris, RG.
- LTP long-term potentiation
- NMDA receptor is very important in memory and learning. It is considered to play a role.
- Intrahippocampal administration of a glycine site antagonist impairs working memory performance Pharmacol., 253, 183-7, 1994, and Fishkin, R J., et al., D-cycloserine attenuates scopolamine-induced learning and memory deficit s in rats., Behav. Neural. Biol. , 59, 150-7, 1993).
