Abstract

The invention relates to an application of Chukrasone A in preparing MAO (Monoamine Oxidase) inhibitor medicines. Compared with existing MAO inhibitors, the MAO inhibitor provided by the invention is greatly improved in inhibitory activity and selectivity to MAO-A and MAO-B. The use of the Chukrasone A for preparing MAO inhibitor medicines provided by the invention is disclosed for the first time. As the framework type belongs to a brand-new framework type, and the inhibitory activity of the Chukrasone A to MAO is unimaginably strong, the probability of giving any enlightenment by other compounds does not exist. The Chukrasone A has remarkable substantial characteristics and meanwhile has remarkable progress for treating diseases associated to MAO disorder.

Description

1. Technical field [0001] The present invention relates to the application of Chukrasone A in the preparation of monoamine oxidase (MAO) inhibitors. 2. Background technology [0002] Since the anti-tuberculosis drug isoniazid was found to be a potential MAO inhibitor, research on MAO inhibitors has become a hot topic. Iproniazid became the first MAO inhibitor, because it was discovered that this kind of MAO inhibitor containing hydrazine structure can also inactivate P450s and cause liver toxicity; and studied the non-hydrazine MAO inhibition represented by tranylcypromine Agents, this category can be called the second generation. But because "cheese reaction" causes high blood pressure, its application is limited. Therefore, it is quite necessary and urgent to develop a newer and more efficient monoamine oxidase inhibitor. [0003] The compound Chukrasone A involved in the present invention is published in 2012 (Liu, H. B. et al., 2012. Chukrasones A and B: Potential Kv1...
