The invention discloses a compound with remarkable 5-hydroxytryptamine (5-HT)
reuptake inhibition activity, a preparation method of the compound and application of the compound in preparation of anti-depression drugs. And the compound is a compound Oreonudine C. The invention further discloses a preparation method of the compound. The preparation method of the Oreonudine C comprises the following steps: extracting with 95%
ethanol, acidifying the extract, extracting with
petroleum ether, adjusting the
acid water layer to be alkaline with alkali liquor, extracting with
chloroform, and performing
silica gel column chromatography, C18 ODS
column chromatography and preparative
high performance liquid chromatography on the
chloroform extraction part to obtain the Oreonudine C. The invention further discloses a preparation method of the Oreonudine C. The preparation method of the Oreonudine C comprises the following steps: extracting with 95%
ethanol, acidifying the extract, extracting with
petroleum ether, adjusting the
acid water layer to be alkaline with alkali liquor, and obtaining the Oreonudine C. In-vitro experiments show that the compound Oreonudine C remarkably inhibits
reabsorption of 5-HT (the inhibition rate is 60.4%) in mouse hippocampal neuronal cells HT22, and the inhibition rate of the compound Oreonudine C is superior to that of a
positive control drug amitriptyline (the inhibition rate is 53.6%). The invention provides an important candidate compound for developing efficient and novel
antidepressant drugs.
