Embodiment 1

[0026] Example 1 The protective effect of drugs on nerve cells

[0027] MTT method is used to screen the protective effect of the compounds disclosed in the present invention on hydrogen peroxide-induced injury of PC12 nerve cells. PC12 neuronal cells were purchased from the Cell Bank of the Type Culture Collection Committee of the Chinese Academy of Sciences, and used DMEM medium containing 10% FBS at 37°C in 5% CO 2 Routine culture in a saturated humidity incubator. Take cells in good logarithmic growth phase, digest with 0.25% trypsin, make cell suspension, count 5×10 4 cells / mL, the cell inoculation volume was 100 μL / well, and cultured in an incubator. After 24 hours, different concentrations of the compound solutions disclosed in the present invention (final concentration 1, 10 μM) were added, and each group had 6 replicate wells. After 2 hours of pre-incubation, 100 μM hydrogen peroxide was added to the model group and the treatment group respectively. After 30 ...

[0032] Example 2 Neuroprotective effects of drugs on Alzheimer's disease model SAMP8 mice

[0033] 1. Experimental materials

[0034] 36 clean-grade 39-week-old male SAMP8 senile dementia mice, weighing 30g ± 2g; 12 SAMR1 anti-aging mice of the same age, all provided by the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine (animal qualification certificate number: W-J Jinshi Momentum M Zhunzi No. 006). They were routinely housed in the Animal Room of West China School of Pharmacy, Sichuan University.

[0035]Reagents and medicines: Compound 1 disclosed in the present invention has a purity >99%, and is prepared at the required concentration before use. The rest of the reagents were commercially available analytically pure.

[0037] 2.1 Animal grouping and administration

[0038] All mice were adapted to the experimental environment for 7 days before administration, and were randomly divided into model gro...

Embodiment 3

[0053] Example 3 Neuroprotective effects of drugs on rats with vascular dementia

[0054] 1. Experimental materials

[0055] Male Wistar rats, weighing 280–300 g, were purchased from the Animal Experiment Center of Sichuan University. They were routinely housed in the Animal Room of West China School of Pharmacy, Sichuan University.

[0056] Reagents and medicines: Compound 1 disclosed in the present invention has a purity >99%, and is prepared at the required concentration before use. The rest of the reagents were commercially available analytically pure.

[0057] 2. Methods and results

[0058] 2.1 Animal modeling, grouping and administration

[0059] Rats were anesthetized by intraperitoneal injection of 3.5% chloral hydrate (350 mg / kg), the bilateral common carotid arteries were separated and ligated, and the bilateral common carotid arteries were not ligated in the sham-operated normal group. Seven days after the operation, the hidden platform screening experi...

Abstract

The invention provides a salicylic acid compound and a medicinal composition of a pharmaceutically acceptable salt thereof. The compound can be added into a pharmaceutically permissible excipient to prepare various pharmaceutically acceptable medicinal preparations. Research proves that the compound disclosed by the invention has a protection effect on in-vitro cultured nerve cell damage induced by hydrogen peroxide, the learning and memory capabilities and the neuron-pathologic change of patients with senile dementia and vascular dementia can be dose-dependently improved, and the compound can be used for effectively treating and/or preventing the neurodegenerative related disease.

Description

technical field [0001] The invention belongs to the field of medicine, and relates to the use of a class of salicylic acid compounds and pharmaceutically acceptable salts thereof in the preparation of drugs for the treatment and / or prevention of neurodegenerative related diseases, including but not limited to vascular dementia, Alzheimer's Neurodegenerative diseases such as Haimer's disease (Alzheimer's disease), Parkinson's disease, Huntington's disease, HIV-related dementia, multiple sclerosis, progressive lateral sclerosis, neuropathic pain, glaucoma, etc. Background technique [0002] Vascular dementia (VD) is a mental and cognitive disorder caused by various types of cerebrovascular diseases (including ischemic cerebrovascular disease, hemorrhagic cerebrovascular disease, acute and chronic hypoxic cerebrovascular disease, etc.). It is a clinical syndrome of cognitive dysfunction, and its main clinical manifestations include: decline in cognitive ability, memory, and soc...
