Embodiment 1

[0062] Example 1: Western-blot (Western blotting) determination of the effect of gossypol acetate on Mecp2 content in rat brain

[0063] The embodiment of the present invention adopts the method of western-blot (Western blotting) to determine the change of the content of Mecp2 in the rat brain, and the specific steps are as follows:

[0064] Fifty-six 8-week-old male SPF (Specific pathogen Free, no specific pathogen) wistar (rats) were randomly divided into two groups: blank group (administered edible oil and distilled water), gossypol acetate group (administered gossypol acetate 50mg / kg and distilled water, where 50mg / kg refers to a single dose of 50mg per kilogram of rat). The above-mentioned rats were raised in separate cages, free to eat and drink, and kept the indoor temperature at 25±1°C, relative humidity at 55±5%, and 12h light / 12h dark cycle lighting. The administration method was oral administration. Except for the blank group, the gossypol acetate group was given m...

Embodiment 2

[0098] Embodiment two: Immunohistochemical assay is used to determine the influence of gossypol acetate on Mecp2 content in rat brain

[0099] Fifty-six 8-week-old male SPF (Specific pathogen Free, no specific pathogen) wistar (rats) were randomly divided into two groups: blank group (administered edible oil and distilled water), gossypol acetate group (administered gossypol acetate 50mg / kg and distilled water, at this time, 50mg / kg refers to a single dose of 50mg per kilogram of rats), the above-mentioned rats were kept in separate cages, free to eat and drink, and kept the indoor temperature at 25±1°C and relative humidity at 55°C ±5%, 12h light / 12h dark cycle lighting. The administration method was oral administration. Except for the blank group, the gossypol acetate group was given medicine once every other day for modeling, and the administration was continued for two weeks. Rats in the above two groups were sacrificed after two weeks of separate cage feeding, and the ma...

Abstract

The invention discloses a novel application of gossypol acetate in the field of pharmacy, and in particular relates to an application of gossypol acetate in preparing medicines for preventing, relieving and/or treating reye's syndrome, and belongs to the field of pharmacy. Reye's syndrome is a cryptogenic acute encephalopathy syndrome in the childhood phase, and studies discover that loss or mutation of MeCP2 gene has a direct causal relationship with the reye's syndrome, and loss of the MeCP2 gene can cause reye's syndrome developing on a mouse. Experiments indicate that the content of the MeCP2 gene in the brain of a rat can be remarkably increased by administrating the rat with gossypol acetate, so that the content of the MeCP2 gene in the brain of a patient can be remarkably increased by using the gossypol acetate for preventing, relieving and treating the reye's syndrome caused by MeCP2 mutation, the development of the nerve cell of the patient can be promoted, functions of the nervous system can be restored, and the possibility of healing the patient can be increased. Therefore, according to the application of the gossypol acetate in preparing the medicine for resisting reye's syndrome, the medicine can be used for preventing, relieving and/or treating the reye's syndrome.

Description

technical field [0001] The invention relates to the application of gossypol acetate in the pharmaceutical field, in particular to the application of gossypol acetate in the preparation of anti-Reye's syndrome medicine. Background technique [0002] Reye's syndrome is a severe X-linked neurodevelopmental autism spectrum disorder (autism spectrum disorder), which is recognized at home and abroad as the single gene cause of MeCP2 (methyl CpG–binding protein 2, methylated CpG binding protein 2). disease disease. Studies have found that there is a direct causal relationship between the loss or mutation of the MeCP2 gene and Reye's syndrome, which provides a potential therapeutic target for Reye's syndrome. Studies on the mouse model of Reye's syndrome found that the restoration of MeCP2 function can reverse the neurological symptoms of adult mice, making it possible for patients with Reye's syndrome to be cured. [0003] Gossypol acetate is a polyphenolic compound with extensiv...
