Abstract

The invention relates to a medicine composition with high safety, a preparation method and an application thereof. The medicine composition contains cinepazide or salt thereof which is acceptable in pharmacy and a structural compound which has the content not higher than 0.5% and is shown in the formula (III). The cinepazide medicine composition and a preparation thereof have better safety, effectiveness and stability and can effectively lower or avoid the adverse reactions of hemogram lowering and the like of a patient caused by the cinepazide. Furthermore, the invention also separates, purifies and characterizes a novel cinepazide nitrogen oxide, researches the novel cinepazide nitrogen oxide fully and discovers that the toxicity of the compound is far greater than that of the cinepazide and the compound has an insecticidal activity which is different from that of the cinepazide. Meanwhile, the research discovers that the cinepazide nitrogen oxide can cause the leukopenia of animals, even influences the formation and the differentiation of granular cells and is possibly a main reason of the adverse reactions of the hemogram lowering and the like of the patient caused by the cinepazide.

Description

technical field [0001] The invention belongs to cardiovascular and cerebrovascular expansion drugs, and in particular relates to a high-safety cinepazide medicinal composition, a preparation method thereof and an application thereof. Background technique [0002] Cardiovascular and cerebrovascular diseases, like cancer, have become common and frequently-occurring diseases that seriously threaten people's health. Therefore, the preparation and selection of safer and more effective cardiovascular and cerebrovascular drugs has become an important research topic in the field of medicine. [0003] Cinepazide is a cardiovascular and cerebrovascular dilating drug. It has been widely used in countries all over the world because of its definite curative effect. Its chemical name is (E)-1-{4-[(3′,4′,5′- Trimethoxycinnamoyl)]-1-piperazine}acetylpyrrolidine, having the following structure: [0004] Formula (I). [0005] Cinepazide is mainly used in the prevention and treatment of t...
