Problems solved by technology

However, these drugs have a short half-life and low blood-brain barrier permeability, which cannot enhance the repair and regeneration capabilities of the cells themselves, and can only alleviate and improve neurodegenerative diseases.

Embodiment 1

[0030] Example 1: A screening model for promoting nerve regeneration in vitro using the neuroma cell line N1E115 as the experimental object

[0031] The invention establishes a screening model for promoting the axon growth of N1E115 cells in vitro. Undifferentiated N1E115 cells were cultured in DMEM medium containing 10% fetal bovine serum FBS, 1% penicillin-streptomycin, placed in a constant temperature and humidity of 5% CO 2 , cultured in a 37°C incubator; the induced differentiation N1E115 was cultured in DMEM medium without FBS, 1% penicillin-streptomycin, and placed in a constant temperature and humidity of 5% CO after adding the test compound 2 , continue culturing in a 37°C incubator for 3-4 days, and then take pictures under a 20X microscope, randomly photograph 8 fields of view in each well, and count 50 cells in each field of view to count the percentage of differentiated cells and the change of cell axon length. (Yamashita H, Muroi Y, Ishii T. Saccharin enhances n...

Embodiment 2

[0043] Example 2: A screening model for promoting nerve regeneration in vitro using the undifferentiated rat adrenal pheochromoma cell line PC-12 as the experimental object

[0044]In the present invention, the undifferentiated rat adrenal pheochromoma cell line PC-12 is selected, and under the condition induced by low concentration of NGF, a screening model for promoting nerve regeneration is established to evaluate the action effect of magnolanediol. (Ishima T, NishimuraT M, Hashimoto K. Potentiation of nerve growth factor-induced neurite outgrowthin PC12 cells by donepezil: role of sigma-1 receptors and IP3 receptors. [J]. Progress in Neuro-Psychopharmacology and Biological Psychiatry, 2008, 32 (32): 1656-9.)

[0045] Undifferentiated PC-12 cells were cultured in DMEM medium containing 10% horse serum HS, 5% fetal bovine serum FBS, 1% penicillin-streptomycin, placed in constant temperature and humidity 5% CO 2 , cultured in an incubator at 37°C; the PC-12 cells induced to ...

Embodiment 3

[0053] Example 3: A screening model for promoting nerve regeneration in vitro with primary cortical neuron cells as the experimental object

[0054] Primary cortical neuronal cells were selected to demonstrate the neuroregenerative effects of magnolanediol. Take suckling rats from pregnant rats at 16-18 days of pregnancy, separate cerebral cortex cells, inoculate in 24-well plates pre-coated with PLL, add neuron culture medium, add different concentrations after 4 hours of cell attachment The magnolanediol (0.1, 1, 10 μM) was cultured for 24 hours and photographed, and 8 fields of view were randomly photographed in each well under a 20X microscope, and 50 cells in each field of view were counted. Measure and analyze the nerve cell protrusions in the selected microscope pictures.

[0055] The results show that magnolanediol can significantly promote the length of axons, the number of axons, and the branching of dendrites after acting on primary cortical neurons of rats for 24 ...

Abstract

The invention relates to magnolia odoratissma alkyl diol which promotes regeneration of a nerve cell system and nerve cell axons, can promote increase of low-concentration induced PC-12 cell differentiation amount, obvious increased of the cell axon amount, obvious increase of axon length, obvious increase of neuroma mother cell N1E-115 axon length and prolonging and regeneration of fetal rat primary cortical neuron axons.

Description

technical field [0001] The invention relates to the field of natural products, in particular to the use of magnolanediol in preparing a composition for restoring nerve function. Background technique [0002] Magnolane diol is a chemical component isolated from the Caragana gambolica shrub of the family Caragana fabaceae. Many plants of the same genus of Caragana shrubs are commonly used ethnic medicines in my country. According to literature reports, there are oligostilbenes, triterpenes, flavonoids and other components in the plants of this genus, which show anti-inflammatory, anti-tumor, anti-virus, Antihypertensive and other pharmacological activities (Sun Zhihua; Zhang Su; Shi Jiao; Hu Changqi. Sesquiterpenoids in Caragana intermedia Organic Chemistry, Vol. 24, No. 7, 2004, 806-810). But so far, there is no relevant report about the biological activity of magnolanediol. [0003] Central nervous system (CNS) disease is one of the diseases that seriously endanger human he...
