Technical Field
The invention belongs to the technical field of medicines, and relates to application of schisanhenol (Hernandezine) and derivatives thereof in preparation of medicines for treating depression and prepared antidepressant medicines.
Background
Major Depressive Disorder (MDD) is a serious, recurrent disabling psychotic disorder. About 3 billion depression patients worldwide. The incidence of depression in china is 4.2%, with about 5600 ten thousand patients suffering depression. Depression is the second leading cause of life loss (years) due to disability, and has become a major public health problem that urgently needs to be solved. Depression is clinically manifested as depressed mood, hyposis, and even pessimistic and boredom, with suicide attempts or behaviors. The current first-line clinical antidepressants mainly comprise selective 5-hydroxytryptamine reuptake inhibitors, 5-hydroxytryptamine and norepinephrine reuptake inhibitors and the like, but the drugs have slow effect, narrow action spectrum and are easy to relapse after drug withdrawal. Despite the use of multiple antidepressant medications, about 30% of patients become refractory Depression (TRD). Patients with this type of refractory depression present a higher risk of social burden and risk of suicide. Therefore, the search for new antidepressant drugs with good compliance, few side effects and novel pharmacological mechanisms has great clinical requirements, and is also a hot spot of international research at present.
Schisanhenol (schizanenol; Gomisin K3; (+) -Gomisin K3; NSC 330515) is also known as (+) -Gomisin K3, deoxyschizandrin. A biphenyl cyclooctene lignin component extracted and separated from various schisandra plants.

After 5 days of administration, both low and high doses produced significant antidepressant effects. The medicine has the advantages of remarkable antidepressant effect, quick action, small dosage, small side effect and the like. In the forced swimming test of mammal mice, the schisanhenol and the derivatives thereof have more obvious antidepressant effect than the conventional antidepressant drug imipramine.
Compared with the prior art, the invention has the beneficial technical effects that:
1. the invention provides application of schisanhenol or derivatives thereof in preparing anti-depression drugs. The research result of the invention shows that in the tail suspension experiment of a mammal mouse, the schisanhenol or the derivative thereof has the effect of quickly resisting depression and is more effective than the conventional antidepressant drug imipramine.
2. The invention adopts forced swimming experiment and mouse tail suspension experiment as drug screening experiment. Forced swimming experiments and mouse tail suspension experiments are two common animal behavior despair depression model experiments, and can better ensure the reliability of screening results. Forced swimming experiments in mice have been used for screening of many antidepressants. Moreover, most of the antidepressants with clinical treatment effects are also proved to be effective in reducing immobility time in forced swimming experiments.
By immobile, it is meant that "the animal stops struggling in water, or is in a floating state, only exposing nostrils to keep breathing, and only having small limb movements to keep the head floating on the water". Drugs to be screened were administered prior to the assay. Animals cannot escape from the harsh environment due to downstream swimming in a forced state, resulting in despair behavior of the animals. The model method is simple, convenient and reliable, and is widely used for screening and evaluating the antidepressant. The tail suspension experiment of the mouse is that the mouse does not struggle under the tail suspension state and presents a special quiet immobility state, and the antidepressant can obviously shorten the duration time of the immobility state. During the test, the tail of the mouse is fixed and suspended upside down. The tail of the mouse is not twisted and folded. And recording the immobility time. The immobility indexes are as follows: animal limbs and trunk struggle without twisting. The tail suspension experiment is sensitive to various antidepressants, and avoids the interference of temperature and animal movement dysfunction in the swimming experiment, so that the results of the forced swimming experiment can be effectively verified and supplemented when some mice are used for screening the antidepressants.
3. Shows stronger antidepressant effect than imipramine. In a tail suspension experiment of a mouse animal model, it is found that the depression symptom of a high-dose group mouse (10mg/kg) of schisanhenol and derivatives thereof starts to be relieved 60 minutes after injection, namely, the activity is more and more frequent compared with a blank control group, and the immobility time is obviously shortened. After 5 days of injection, the time of suspending tail and immobility of the tail is obviously shortened by schisanhenol and derivatives thereof. Schisanhenol and its derivatives show stronger antidepressant effect than imipramine at a dose (10mg/kg) lower than that of imipramine (15 mg/kg).
4. The invention also carries out an Open field test (Open field test) of the mouse to check the autonomous activity of the mouse and avoid the interference of central stimulant. Since the shortening of the immobility time of animals in classical animal models of depression may be due to the central excitatory action of the drug, the present invention also simultaneously performs mouse open-field experiments. The result shows that the high concentration of the schisanhenol and the derivatives thereof have no significant influence on the autonomous activity of mice compared with the control group, so that the possibility of causing mania by stimulant can be eliminated, and the schisanhenol and the derivatives thereof are proved to have significant antidepressant effect.
5. The antidepressant medicament taking the schisanhenol or the derivative thereof as the effective component is expected to become a new antidepressant medicament with high speed, high efficiency and a new mechanism.

Test example 1 Effect of schisanhenol on animal Depression model Tail suspension test
Experimental animals: c57BL/6 mice, male, 30-40 grams in weight, supplied by sbefu (beijing) biotechnology limited, license number: SCXK (Jing) 2019-. The animals are raised in cages with the light and shade period of 12h/12h, the room temperature of 20-22 ℃, the water is free, and the feed is provided by the Huada protein experimental animal center.
Experimental drugs: schisanhenol is extracted from institute of pharmaceutical sciences of Chinese academy of medicine, and its chemical purity and structural analysis are shown in FIGS. 2, 3 and 4. Imipramine hydrochloride (Imipramine hydrochloride) is a product of Sigma company, the product number is I7379, and the batch number is O56K 1380.
Experimental equipment: a cross bar; rubberized fabric; a camera (a mobile phone); JUNSO multifunctional timer.
The experimental steps are as follows: male C57BL/6 mice were acclimatized for one week and divided into 5 groups of 6-8 mice each. The two groups are respectively a dimethyl sulfoxide DMSO control group (DMSO is dissolved in normal saline), a schisanhenol low-dose group (schisanhenol-L is dissolved in DMSO at 5mg/kg), a schisanhenol high-dose group (schisanhenol-H is dissolved in DMSO at 10mg/kg), a traditional antidepressant drug imipramine positive control group (15mg/kg imipramine is dissolved in normal saline), and a normal saline control group. The medicine is administrated by intraperitoneal injection at 10 am according to 0.1ml/10g body weight, and after 60 minutes of injection, tail suspension experiments are carried out on 6-8 mice in each group; in the tail suspension experiment of the mouse, the tail of the mouse is stuck on a horizontal cross bar at a position 2 cm away from the tail tip by using an adhesive tape, so that the animal is in an inverted hanging state, and the head of the animal is 15 cm away from a table top. The observation time was 6 minutes and the cumulative immobility time was recorded over 4 minutes.
The immobility indexes are as follows: neither the animal's limbs nor body struggles.
The statistical method comprises the following steps: the results are expressed as mean ± SE and three samples were tested by ANOVA. The average comparison of the two samples (imipramine and saline) was performed using the t-test.
The depression symptom of the mice in the schisanhenol high-dose group starts to be relieved 60 minutes after injection, namely struggle movement is more and more frequent compared with a blank control group, and the immobility time is obviously shortened. The activity of the imipramine positive control group and the physiological saline control group is not enhanced to be obvious within 60 minutes after injection. The results observed after 60 minutes of injection, as shown in FIG. 5, the immobility time of the mice in the low-dose and high-dose groups of schisanhenol was reduced from 163.20 + -5.27 s to 130.5 + -7.35 s (P < 0.05) and 138.4 + -4.76 in comparison with the DMSO control group.
The result shows that the schisanhenol can take effect within a short time and can resist depression despair symptoms caused by forced tail suspension of mice.
Test example 2 Effect of schisanhenol on forced swimming test of animal depression model
Experimental animals: c57BL/6 mice, male, offered by sbefu (beijing) biotechnology limited, license number: SCXK (Jing) 2019-. The animals are raised in cages one week before the experiment, the light and shade period is 12h/12h, the room temperature is 20-22 ℃, the water is freely eaten, and the feed is provided by the Huada protein experimental animal center.
Experimental drugs: schisanhenol. The positive control Imipramine hydrochloride (Imipramine hydrochloride) is a product of Sigma company, the product number is I7379, and the batch number is O56K 1380.
An experimental instrument: glass cylinder (height 40cm, diameter 14 cm); a mouse open box (the length and the width are 50cm, the height is 40cm, and the bottom is 16 equal parts); a thermometer; JUNSO multifunctional timer.
The experimental steps are as follows: drug preparation same tail suspension experiment. Animal drug injection: c57BL/6 mice, age 7 weeks, weigh 30-40 grams, acclimate for one week and begin the experiment. Animals were randomly grouped into 5 groups of 8-10 animals each. Intraperitoneal injections were started at 10 am each day. The injection amount is 0.3 ml/30 g, the injection is performed intraperitoneally once a day, and a forced swimming experiment is started five days after the injection.
Forced swimming experiment: each group of C57BL/6 mice was placed individually vertically into a plexiglas cylinder (40cm height by 14cm diameter) at a water depth of 25cm and a water temperature of 21-23 ℃. The administration group and the control group were recorded for 6 minutes, and the cumulative immobility time in the following 4 minutes was compared for each group of mice.
And (3) judging the motionless time: the mouse floats on the water surface, does not try to climb out of the cylinder, and only does some action which is necessary to keep the head of the mouse on the water surface.
The statistical analysis method comprises the following steps: the results are expressed as means ± SE and the comparison of the mean of the two samples is performed by t-test.
As shown in FIG. 6, compared with DMSO control group, the immobility time of the mice in the schisanhenol high-dose group and the low-dose group is significantly reduced within 4 minutes of forced swimming, and the immobility time of the mice in the schisanhenol low-dose group and the schisanhenol high-dose group is reduced to 24.50 +/-4.50 s (p is less than 0.01) and 27.00 +/-3.65 from 58.13 +/-14.00 s, which are respectively reduced by 57.85% and 53.55% compared with that in 1% DMSO control group. The immobility time of mice treated by the traditional antidepressant drug imipramine (15mg/kg) is reduced from 75.54 +/-6.06 s to 57.17 +/-5.66 s, which is reduced by 24.32%, and the anti-depression effect of schisanhenol is stronger compared with imipramine.
Test example 3 mouse open-field test
Since the reduction in immobility time in classical animal models of depression is probably due to the central excitatory action of the drug, we performed a mouse open field experiment to examine the central excitatory properties of schisanhenol.
The experimental results show that the mice enter the open box for the next 5 minutes of 6 minutes, counted by ANY-maze software, the total distance of movement in the open box is not changed significantly (Anova, p > 0.05, N ═ 21) after the schisanhenol is treated with high dose (18.26 +/-3.34 m) and low dose (17.31 +/-2.19 m) compared with the control group (16.62 +/-4.32 m), so that the possibility of inducing mania can be eliminated, and the schisanhenol indeed has a remarkable anti-depression effect.
Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
