Abstract
Description
Heterocyclic alkyl carboxylic acid derivatives, intermediates and methods of preparation and use thereof TECHNICAL FIELD
[0001] The present application relates to the technical field of pharmaceutical chemistry, and particularly relates to a heterocyclic alkyl carboxylic acid derivative and a preparation method and use thereof. BACKGROUND
[0002] Human mental activities include sensation, perception, memory, thinking, emotion, attention, will, intelligence, personality, consciousness and the like. Any abnormal change in any aspect or mental activities and environment incoordination can show mental activity disorder or mental abnormality. Bipolar disorder is a neuropsychiatric disease with high incidence, high heritability and high mortality, which seriously affects people's physical and mental health and social harmony. Bipolar disorder, also known as manic depression, is a serious mental illness characterized by alternating episodes of mania and depression. Manic episode is a major characteristic of bipolar disorder, and its main manifestations include elevated mood, irritability, excessive thinking activity and reduced sleep demand; depressive episode is another major feature of bipolar disorder, and its manifestations include low mood, loss of interest and reduced activity.
[0003] However, the pathogenesis of bipolar disorder has been a long-standing scientific problem in the field of neuroscience and medicine. Among numerous bipolar disorder and depression patients, 70% lack effective treatment methods. Traditional antidepressants and antipsychotics are mainly used for targeting based on monoamine hypothesis and for central nervous system neurotransmitter receptors, and have the disadvantages of slow effect, low efficiency, large side effects, poor effect of single drug, risk of suicide and self-injury, and the like. The essential reason is that the mechanism of mental illness is not clear, and there is a lack of new mechanism and new target as a drug development direction and treatment method.
[0004] Patent CA2197172A1 discloses new alkylamino derivatives, pharmaceutical compositions comprising such compounds and the use of such compounds in the treatment of central nervous system disorders and several other disorders, including the use of the following compounds as new alkylamino derivatives of sigma 2 selective ligands:
[0005] Patent CN101304973A discloses compounds that modulate the interaction of nerve growth factor and its precursors with neurotrophin receptors and their pharmaceutically acceptable compositions, and the treatment of disease conditions mediated by this interaction, such as pain, inflammatory diseases and neurological diseases, the neurological diseases treated are selected from schizophrenia, bipolar disorder, depression, Alzheimer's disease, epilepsy, multiple sclerosis, amyotrophic lateral sclerosis, stroke, cerebral ischemia, neuropathy, retinal pigment degeneration, glaucoma, arrhythmia, Huntington's disease, and Parkinson's disease, and the specific compounds are as follows:
[0006] Synaptotagmin (Syt) is a presynaptic vesicle protein, and is one of the key proteins involved in the process of neurotransmitter release and physiological functions of brain learning and memory. Syt is a family of membrane transport proteins. They are characterized by containing two calcium binding regions: C2A and C2B. They are characterized by N-terminal located in the vesicle, C-terminal located in the cytoplasm, and only one transmembrane region. The cytoplasmic region of Syt is mainly composed of two Ca 2+ binding regions with repeated sequences-C2A and C2B. Close to the N-terminal is called C2A, and close to the C-terminal is called C2B. So far, the role of Syt in neurotransmitter release has been deeply studied. The release of neurotransmitter between synapses is one of the most important biological phenomena for the nervous system to complete its physiological functions. Neurotransmitter release is induced by Ca 2+ inflow to induce exocytosis of synaptic vesicles containing neurotransmitters and presynaptic membrane fusion, Ca 2+ binding in the cell interior needs to be combined with the Ca 2+ sensor in the cell to cooperatively control vesicle exocytosis release. Syt is a Ca 2+ sensor protein of vesicle membrane fusion, which can interact with SNARE complex to regulate the fusion of vesicle membrane and plasma membrane, and plays an important regulatory role in the secretion of nerve, endocrine cells and other cells.
[0007] Syt7 is a member of the Syt family of 17 members, which functions as a calcium sensor through two calcium-binding domains (C2A / C2B) and plays an important role in synaptic vesicle release and synaptic plasticity. The soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) is a small, conserved family of eukaryotic proteins that mediates membrane fusion between organelles and the plasma membrane. At the presynaptic terminal, Syt7 binds calcium ions through C2A / C2B after an action potential-induced massive influx of calcium ions, and interacts with the core proteins of vesicle release and their SNARE complex, and the lipid bilayer of the plasma membrane, to induce the slow-phase asynchronous release of synaptic vesicles (SVs). Moreover, Syt7 deficiency causes defects in SV pool replenishment in train-induced release. On the other hand, studies have shown that NMDAR (glutamate receptor) plays an important role in mouse depressive-like behavior, and NMDAR activated by spontaneous release of glutamate may play an important role in this process. Based on these studies, further studies have found that Syt7 is located in the marginal part of the presynaptic active zone (AZ), and the triggered spontaneous release of glutamate can specifically activate the GluN2B-NMDAR located in the marginal part of the synapse; the small part of SVs controlled by Syt7 cannot participate in the release in the train, thus leading to insufficient SV replenishment; and Syt7 deficiency can lead to the generation of postsynaptic homeostatic plasticity, thereby up-regulating the expression level of NMDAR. Studies have shown that Syt7 can act as a calcium sensor to drive the slow-phase asynchronous release of GABA (gamma-aminobutyric acid) in GABAergic neurons.
[0008] Patent WO2021147977A1 discloses that the expression of Syt7 gene in hippocampal neurons differentiated from induced pluripotent stem cells (iPSCs) of bidirectional mood disorder patients is significantly deficient; Syt7 gene knockout mice exhibit symptoms of spontaneous cycle of mania and depression of bidirectional mood disorder; and the expression level of Syt7 mRNA in the blood plasma of BD patients is significantly lower than that of healthy control group; the level of Syt7 mRNA in blood cells is also reduced, and the result is consistent with the detection in the blood plasma. The signal pathway related to the Syt7 gene and the expression product thereof play a key role in the mood cycle of bidirectional mood disorder, and the molecules targeting the signal pathway related to the Syt7 gene can provide help for the diagnosis and treatment of bidirectional mood disorder. The use of the Syt7 gene and / or the expression product thereof in the preparation of a drug for treating bidirectional mood disorder and / or its complications is provided. According to the embodiments of the present application, the expression product of the Syt7 gene can be used as a protein drug, and by administering an appropriate amount of protein drug to patients with bidirectional mood disorder or patients with complications, the content of the expression product of the Syt7 gene in the body can be increased, so that it can be used for treating bidirectional mood disorder or complications.
[0009] At present, there are few compounds for treating mental diseases such as depression and bipolar disorder by acting on Syt7, and therefore, the present application provides a heterocyclic alkyl carboxylic acid derivative with a new structure based on the mechanism, and through in vitro activity detection and in vivo animal behavior experiments, it is proved that the heterocyclic alkyl carboxylic acid derivative has good treatment effect on neurological diseases such as depression and bipolar disorder. In addition, Syt7 has the biological activity of promoting vesicle release, and the metabolism of many hormones, such as insulin, is released through vesicle release, so the heterocyclic alkyl carboxylic acid derivative can also be used for treating metabolic diseases by acting on Syt7.
