Embodiment 1

[0037] Preparation of active ingredient calamus amide compounds (extraction and separation process)

[0038]Herbal decoction pieces of Shichangpu were purchased from Anhui Jiren Pharmaceutical Co., Ltd. (batch number: 120519, specification: 1kg / bag, origin: Anhui), about 20kg, decocted 3 times with 8, 6, and 6 times the amount of water, 1.5h each time , combined extracts, recovered under reduced pressure to a small volume (80L), filtered through D101 macroporous resin column chromatography, ethanol-water (v / v) gradient elution, recovered solvent under reduced pressure, obtained 30%, 50%, 70%, 95% 4 ethanol eluates.

[0039] The 30% ethanol eluate was dispersed in water and adjusted to pH=3-4 with formic acid, extracted three times with an equal volume of n-butanol, and the n-butanol extract was recovered under reduced pressure to obtain a dry extract, which was dissolved in water and subjected to ODS column chromatography (methanol-water gradient elution), obtain 6 components...

Abstract

The invention provides a calamus amide compound as well as a preparation method and application of the calamus amide compound. The compound is (E)-methyl- 4-[3-(4-hydroxy-3-methoxyphenyl)acrylamido]butanoate or a (Z)-methyl- 4-[3-(4-hydroxy-3-methoxyphenyl)acrylamido]butanoate enol isomer, is separated and purified from roots and stems of acorus tatarinowii serving as an araceae acorus plant, has the effect of promoting the activity of a 5-serotonin transporter (SERT), can be used as a drug for treating depressive disorder, anxiety disorder, schizophrenia, obsession, neurodegenerative diseases, drug addiction or digestive system dysfunction and other diseases, and has an important drug development value.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine research, in particular to calamus amide compounds and their preparation methods and applications. Background technique [0002] Serotonin transporter (SERT) is a transmembrane transporter with high affinity for 5-HT, containing about 630 amino acid residues, and its coding gene (SLC6A4) is located on chromosome 7 and 11, respectively. It consists of 14 exons of about 35kb. The SERT protein contains 12-13 transmembrane regions, the N-terminal and C-terminal are located in the cytoplasm, there is a cAMP-dependent protein kinase binding site near the N-terminal, and there is an extracellular region between the third and fourth transmembrane regions. The cyclic portion of is the N-linked glycosylation site. [0003] SERT belongs to Na + / Cl - Dependent transporter, mainly located in 5-HTergic neurons. SERT re-uptakes 5-HT from the synaptic cleft into presynaptic neurons, directly affe...
