Problems solved by technology

Combined with the existing technology, this article can only obtain the protective effect of fingolimod on MN9D cells treated with TNF-α. Whether fingolimod has an effect on Parkinson's patients and whether it can delay the pathological process of PD is currently unknown. No report, no way of knowing

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Experimental materials: human neuroblastoma cell line SH-SY5Y was purchased from ATCC in the United States; C57BL / 6 mice were purchased from the Experimental Animal Center of Shandong University, all male, 8-10 weeks old; fingolimod was purchased from Caymanchemical Company; 6-OHDA was purchased from Sigma; p-AKT, AKT, p-ERK, and ERK antibodies were purchased from Cellsignalingtechnology; BDNF antibodies were purchased from Santacruz; TH antibodies were purchased from Chemicon; LDH and TUNEL kits were purchased from Roche, Annexin-V - FITC was purchased from BD.

[0028] experimental method:

[0029] 1. Use SH-SY5Y neuroblastoma cell culture cell line. Use DMEM-F12 medium with 10% fetal bovine serum. Incubator conditions: 37°C, 5% CO 2 . Change medium once a day. Passage every other day.

[0030] 2. Determination of cell viability by MTT m...

Abstract

The invention discloses new applications of a medicament Fingolimod. The applications comprise applications of Fingolimod or pharmaceutically acceptable salts, esters, and solvates thereof to preparation of a medicament for protecting a dopaminergic nerve cell strain SH-SY5Y damaged by 6-OHDA, and applications of Fingolimod or pharmaceutically acceptable salts, esters, and solvates thereof to prevention and/or treatment of a neurodegenerative disease, wherein the neurodegenerative disease is Parkinson's disease. Researches show that Fingolimod can delay progression of the Parkinson's disease with substantial effects; mechanisms of action of Fingolimod which is used as a novel medicament derived from natural products are different from mechanisms of action of clinical existed medicaments for resisting Parkinson's disease, and mainly have special emphasis on protection effects of dopaminergic neurons, so that a cross resistance phenomenon does not happen.

Description

technical field [0001] The invention relates to a new application of the drug fingolimod. Background technique [0002] Parkinson's disease (PD) is a common neurodegenerative disease among middle-aged and elderly people. With the improvement of people's living standards and the aggravation of population aging, the incidence of neurodegenerative diseases represented by PD is increasing year by year. It is the leading cause of death after cardiovascular diseases and malignant tumors, and it imposes a heavy burden on patients and society. The pathogenesis of PD is complex, and there is no effective treatment at present. Commonly used clinical drugs such as levodopa can only improve symptoms, but cannot delay the disease process. After 3-5 years of application, its curative effect will gradually decline and cause serious side effects such as "on-off" phenomenon. Therefore, it is urgent to find drugs that can delay the disease. Effective therapeutic drugs for the process. [0...
