Abstract

The invention belongs to the technical field of pharmacy, and particularly relates to an application of danshinolic acid A in preparation of medicines for preventing and treating AIDS encephalopathy as well as nerve damages caused by an HIV-1Tat protein. According to the invention, an HIV-1Tat protein damage type nerve cell line PC 12 and nerve cells on mouse brain slices are protected by using danshinolic acid A with different concentrations, and the effect of reducing the death of the nerve cells caused by the Tat protein of the danshinolic acid A is respectively detected by an MTT experiment, LDH detection and a Tunnel experiment; and dendritic spines are labeled by scattering Dil gold particles, and the effect of reducing Tat protein damage synaptic connectivity of the danshinolic acid A is detected. Through statistical analysis of experimental results, the danshinolic acid A is found to have a good protection effect against damages of the nerve cells caused by the Tat protein and can be used for preparing the medicines for preventing and treating the nerve damages caused by the Tat protein as well as the AIDS encephalopathy.

Description

technical field [0001] The invention belongs to the field of pharmaceutical technology, and relates to a new application of salvianolic acid A, a water-soluble component of traditional Chinese medicine Salvia miltiorrhiza Application of protein-induced nerve injury drugs. Background technique [0002] AIDS encephalopathy, now also known as HIV-associated neurocognitive disorders (HAND, HIV-associated neurocognitive disorders), is characterized by motor, behavioral and cognitive impairments, and has recently been divided into three forms according to the severity of the disease: asymptomatic neurocognitive disorders Cognitive impairment (Asymptomatic neurocognitive impairment, ANI), mild neurocognitive disorder (mild neurocognitive disorder, MND) and HIV-associated dementia (HIV associated dementia, HAD). [0003] The detailed mechanism of HIV-1 causing nerve damage remains to be further studied, but it is certain that the neurotoxic protein of HIV-1 damages neurons directly...
