The present invention relates to a composition for preventing or treating neurodegenerative diseases or depression, containing a 2-amino-2-(1,2,3-triazole-4-yl)propane-1,3-diol derivative as an active ingredient and more specifically, to a pharmaceutical composition for preventing or treating neurodegenerative diseases or depression, containing, as an active ingredient, the compound having an effect of directly inhibiting ASM activity.

2-amino-2-(1,2,3-triazole-4-yl)propane-1,3-diol derivative of novel compound for directly inhibiting ASM activity, and use thereof

The present invention relates to a novel use for HDL-ApoM-S1P (a high density lipoprotein in which apolipoprotein M is impregnated with sphingosine-1-phosphate), and more particularly, to using HDL-ApoM-S1P to prevent, improve, or treat degenerative brain disorders (in particular, Alzheimer's disease), cognitive disorders, learning disabilities, and memory disorders, and using HDL-ApoM-S1P to improve cognitive ability, learning ability, and memory. The HDL-ApoM-S1P according to the present invention not only alleviates neuroinflammation but also significantly exhibits improvement effects of cognitive disorder, learning disability, and memory disorder with respect to individuals suffering from degenerative brain disorders (in particular, Alzheimer's disease), and exhibits an effect of greatly reducing amyloid beta and tau deposition. Moreover, increased HDL-ApoM-S1P in the body also has an excellent effect of improving the cognitive, learning, and memory abilities of non-disabled individuals.

Pharmaceutical composition for preventing or treating degenerative brain disorders including HDL-APOM-S1P as active ingredient

The present invention relates to a novel peptide exhibiting an effect of releasing myelopoiesis stem cells into blood and an osteoporosis therapeutic effect and use thereof and, in particularly, to a novel peptide consisting of an amino acid sequence of SEQ. ID.NO:1 which has effects of releasing hematopoietic stem cells into a bloodstream and decreasing osteoclast cells in bone narrow, and a pharmaceutical composition comprising the novel peptide as an active ingredient for preventing or treating neutropenia, anemia or osteoporosis. Because of side effects, the peptide of the present invention not only increases level of leukocytes, red blood cells and platelets in blood, but also alleviates a decrease in bone density, and therefore, can be very usefully used for the development of a prophylactic or therapeutic agent for neutropenia, anemia or osteoporosis.

Neuropeptide Y fragment capable of releasing hematopoietic stem cells into blood and treating osteoporosis

The present invention relates to a method for treating degenerative neurological disorders in a subject in need thereof, comprising administering to a subject in need thereof a therapeutically effective amount of a composition comprising an acid sphingomyelinase (ASM) activity inhibitor or expression inhibitor as an active ingredient.

Method for treating a neurological disorder comprising administering ASM inhibitors

The present invention relates to a pharmaceutical composition containing stem cells in which vascular endothelial growth factor (VEGF) is overexpressed as an effective ingredient for preventing or treating neurodegenerative diseases. The stem cells in which VEGF is overexpressed according to the present invention effectively act against the neurodegenerative disease-induced VEGF reduction of neural stem cells in the SVC to inhibit the abnormal migration of neural stem cells, suppress inflammatory responses, and restrain the accumulation of cholesterol and spingolipids in the cerebral cortex, thus restoring the behavior exercise capacity of animal models, whereby the pharmaceutical composition can be used as an effective therapeutic agent for neurodegenerative diseases.

Pharmaceutical composition containing stem cell in which vascular endothelial growth factor is overexpressed as effective ingredient for preventing or treating neurodegenerative disease

Method for treating a degenerative neurological disorders comprising administering ASM inhibitor

Provided is a composition containing neuropeptide Y for inhibiting side effects of anticancer agents. The neuropeptide Y of the present invention exhibits an effect of mitigating side effects, especially bone marrow injury and neurological disorders, occurring due to the administration of anticancer agents, and thus may be useful as an anticancer adjuvant which may mitigate side effects of anticancer agents and enhance the effect of anticancer agents.

Composition containing neuropeptide Y for inhibiting side effects of anticancer agents

The present disclosure relates to a novel peptide for preventing or treating bone diseases. Further, the present disclosure relates to a polynucleotide encoding the peptide, a vector including the polynucleotide, a host cell transformed by the vector, and a method for producing the peptide by using the host cell. Furthermore, the present disclosure relates to a composition for preventing or treating bone diseases, including the novel peptide. The novel peptide according to the present disclosure induces mobilization of hematopoietic stem cells to blood and causes a decrease in the number of osteoclasts, and, thus, decreases bone erosion caused by osteoclasts, thereby suppressing progress of an osteoporotic lesion. Further, the novel peptide is safe since it does not cause rejection in the body. Furthermore, since the novel peptide is formed of 16 short amino acids, a low dose of the peptide can relieve symptoms of osteoporosis.

Peptides for treating bone diseases and use thereof

There is provided a method for treating or reducing an anticancer agent-induced nephrotoxic injury, the method comprising the step of administering a Y1 receptor activator in an amount effective to treat or reduce the anticancer agent-induced nephrotoxic injury in a subject. Further, there is provided a method for screening an agent for treating or reducing an anticancer agent-induced nephrotoxic injury, the method comprising (a) applying a candidate material to a test sample of renal tissues or cells; and (b) identifying a Y1 receptor signaling in the test sample of renal tissues or cells.

Method using an Y1 receptor activator for treating an anticancer agent-induced nephrotoxic injury

The present invention relates to a composition comprising an ASM inhibitor as an active ingredient for preventing or treating degenerative neurological diseases. According to the present invention, when ASM is partially removed in an Alzheimer's disease model mouse, that is when ASM is inhibited therein, such when as an Alzheimer's disease model mouse with a partial removal of ASM is in a parabionic union with an Alzheimer's disease model mouse, or when an Alzheimer's disease model mouse is injected with the serum of an Alzheimer's disease model mouse from which ASM gene has been removed, the deposition of &#x3b2;-amyloid in the brain tissue is inhibited and the ability to learn and remember are improved, and the present invention confirms such superb effects. Accordingly, ASM inhibitor can be effectively used to prevent or treat degenerative neurological diseases.

The present invention relates to a pharmaceutical composition for preventing or treating osteoporosis which comprises neuropeptide Y as an active ingredient. The neuropeptide Y according to the present invention reduces the expression of a cell adhesion factor in osteoblasts in which a Y1 receptor is present, and consequently an effect of releasing a haematopoietic stem cell from bone marrow into the blood is excellent. When a haematopoietic stem cell is released into the blood, the number of osteoclasts which induce an osteoporotic lesion by differentiation from the haematopoietic stem cell decreases, and thus progression of a bone erosion caused by osteoclasts can be prevented. Accordingly, the neuropeptide Y which is an active ingredient of the composition of the present invention is useful as a therapeutic agent for osteoporosis.
