The invention provides an application of a protopanaxadiol derivative and a protopanaxatriol derivative in the preparation of drugs for treating or preventing neurodegenerative diseases. Pharmacological experiment results show that the above derivatives have a stronger anti-oxidation protection effect than 20(S)-protopanaxadiol and 20(S)-protopanaxatriol in H2O2 damage models of PC12 cells and N2a cells. Two vascular dementia models comprising a repeated occlusion rat bilateral vascular carotid cooperation sodium nitroprusside pressure reduction process stimulated dementia model and a bilateral hippocampus injection Abeta1-42 duplicated senile dementia model can improve the rat space exploration and orientation capability.
Description
technical field [0001] The invention relates to a panaxadiol compound, in particular to a new application of a 20(S)-protopanaxadiol derivative and a 20(S)-protopanaxatriol derivative in pharmacy. It belongs to the field of medicine. Background technique [0002] Neurodegenerative diseases (Degenerative diseases of the central nervous system, ND) are a group of chronic progressive neurological diseases based on primary neuron degeneration. Such diseases mainly include Alzheimer's disease (Alzheimer's disease, AD) (commonly known as senile dementia), Parkinson's disease (Parkinson's disease, PD), Huntington's chorea (Huntington disease), different types of spinocerebellar ataxia ( spinal cerebellar ataxias), amyotrophic lateral sclerosis (amyotrophic lateralsclerosis) and spinal muscular atrophy (spinal muscular atrophy), etc. [0003] Studies have found that ND is caused by a variety of different reasons, including insufficient nutrition provided by neurons or glial cells,...
