Abstract

The invention provides application of Gypensapogenin B to preparation of a MAO (monoamine oxidase) inhibitor. Compared with the existing MAO inhibitor, the MAO inhibitor provided by the invention has greatly improved inhibitory activity and selectivity on MAO-A and MAO-B. The application of Gypensapogenin B to preparation of the MAO inhibitor is firstly publicized; and as a framework type belongs to a brand-new framework type, the framework type has unexpectedly strong inhibitory activity on the MAO inhibitor without any possibility shown by other compounds, and has outstanding substantial characteristics and remarkable progress for treating the diseases related to MAO unbalance at the same time.

Description

1. Technical field [0001] The invention relates to the application of Gypensapogenin B 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 Gypensapogenin B involved in the present invention was published in 2012 (Li, N. et al., 2012. Triterpenes possessing an unprecedent...
