Composition for preventing and treating neuropathic pain containing ginsenoside Rb1 and Rg3, Compound K ， or saponin, containing ginsenosides R1 and R3, CO3, CO3, or ginseng-derived saponin extract as an active ingredient extract from Panax ginseng as an effective ingredient}

The present invention is a composition for preventing and treating neuropathic pain containing ginsenosides Rb1 and Rg3, Compound K, or ginseng-derived saponin extract as an active ingredient, and for preventing and improving neuropathic pain containing the active ingredient. It is about food.

In general, pain is one of the physiological reactions that appear as a life-threatening or defense mechanism against strong external stimuli and is known to play an important role in protecting the body from danger. Pain is divided into nocieptive pain due to tissue damage and neuropathic pain, which does not involve tissue damage but is caused by a nervous system reaction. Invasive pain is known to be closely related to pain, accompanied by an inflammatory response due to tissue damage, and generally disappears as the damaged area heals. Neuropathic pain is a chronic neurological disease caused by damage to the nervous system due to various causes such as trauma, inflammation, ischemic damage, or metabolites (Gilron et al., 2006; Barn, 2006). Neuropathic pain is characterized by accompanying symptoms such as spontaneous pain that occurs without any stimulus and hyperalgesia or allodynia caused by external stimulation. Hyperalgesia is defined as excessive abnormal pain response to noxious stimuli, and allodynia is known as pain response caused by harmless stimuli (Woolf and Mannion, 1999). Neuropathic pain is known to be difficult to relieve pain with conventional painkillers. Neuropathic pain inhibitors include anticonvulsants, such as Gabapentin and Pregabalin, which act on calcium channels, and anticonvulsants, such as Carbamazepine, which act on sodium channels; Serotonin Norepinephrine Reuptake Inhibitor (SNRI) family antidepressants; Four classes of opioids, used only in emergencies, are used clinically.

In particular, complete or partial spinal nerve injury causes neuropathic pain within a few months after injury in the majority of patients with spinal cord injury (Beric, 1997; Christensen and Hulsebosch, 1997; Yezierski. 1996 Yu et. al., 2003) ultimately developing chronic neuropathic pain that persists for a long time (Richards et al., 1980). The pain caused after spinal cord injury mainly occurs in three areas: the above-level pain, which is the pain in the upper part of the injury area, the at-level pain, the pain in the area close to the injury area or the same dermatome. It is divided into below-level pain, which is pain at the lower part of the site (Siddall et al., 1997; Siddall and cousins, 1997). These pains, which occur after spinal cord injury, vary from mild numbness to extreme pain that attempts suicide, and often lead to chronic pain, which bothers patients so that their daily lives are impossible. Moreover, neuropathic pain is not only a pain itself, but also a mental stress such as sleep disorders, anxiety and depression, which not only threaten the quality of life of the patient, but also incur significant treatment costs (for patients with spinal cord injuries). 25 million won per year, about 1 billion won per lifetime), which has become a serious social and economic problem beyond patients and families (Cairns et al., 1996; Segatore, 1994).

Little is known about the mechanisms of pain induced above the injury site, whereas the mechanisms of injury and pain underneath the injury site have been focused on the goal of treating pain after spinal nerve injury. (Hulsebosch. 2002; Yezierski. 2004). Inflammatory responses are known to play a pivotal role in controlling pathologies of acute and chronic spinal cord injury (Bligh, 1992), which are the primary causes of secondary injury following spinal cord injury (Bligh, 1992). Is known to mediate neuropathic pain, especially below-level pain, after spinal cord injury (Hains and Wanxman, 2006; Zhao et al., 2007). Therefore, the control of the inflammatory response through the inhibition of microglial cell activation is a key strategy for the treatment of spinal cord injury and pain control. However, studies on inflammatory response control mechanisms and microglial cell activation are very early and intensive studies are needed.

As mentioned above, drugs used for neuropathic pain are mostly used in the clinic, but each class of drugs has similar side effects, so the combination may worsen the side effects in some patients. There is a problem that the effect is low. In particular, despite the development of various analgesics or analgesic methods to date, 75% of patients with neuropathic pain still report severe pain, but the mechanism of causing neuropathic pain is not clearly established. Since painkillers do not adequately cure neuropathic pain, there is no toxicity and side effects, and more pain inhibitors or therapeutic agents are required.

Accordingly, the inventors of the present invention ginsenoside Rb1 and Rg3, and ginseng-derived saponin extract isolated from ginseng-derived saponin extract, and the composition containing Compound K as an active ingredient in the rat nerve model after injury to the central nerve, respectively When administered, mechanical allodynia and heat hyperalgesia were reduced, and this pain-inhibiting effect occurred through the estrogen receptor and suppressed pain by suppressing the expression of p-p38MAPK, pERK, and pJNK, which are pain related factors in the spinal cord. This invention was completed by confirming that the effect to make is shown.

An object of the present invention is Panax ginseng ginseng ) Saponin extract derived from or to provide a composition for preventing and treating neuropathic pain, or health food containing saponin isolated from the active ingredient.

The test animals were placed under a transparent plastic box (10 cm × 10 cm) on a wire mesh (3 mm × 3 mm). Adaptation was allowed for at least 20 minutes before the start of the sensory test. Von-Frey filaments were applied to both soles. Tactile (mechanical) sensitivity is logarithmic series of stiff nylon Bonfrey single filaments (3.61, 3.84, 4.08, 4.31, 4.56, 4.74, 4.93 and 5.18 mN, Stoelting, WoodDale, IL, USA; equivalent in grams to 0.4, 0.6 , 1.0, 2.0, 4.0, 6.0, 8.0 and 15.0) were used. The avoidance response of the foot to increased mechanical stimuli was assessed by applying sufficient force. The Bonfrey filament was applied to each foot for 3-4 seconds to bend completely. The 50% threshold was confirmed using the up-down method (Chaplan et al. 1994).

In summary, 2.0 g (4.31 mN) of filaments, the middle of eight bone filaments of 0.4 to 15 g, were used for the first time, beginning with the identification of the most sensitive areas at various sites. If the avoidance reaction of the foot did not occur, the filament of the next thickness was repeated. If there is a reaction, apply the weaker filament to the sensitive area. Stimulation was performed at 2 second intervals.

As shown in FIG. 2B, after 4 weeks of preparing the central neuropathic animal model according to the present invention, ginsenoside Rb1, Rg3, and Compound K, or ginseng-derived saponin extract according to the present invention. When not administered, the feet were lifted at 2.9 ± 0.1 g when stimulated with the soles of animal models with weighted and elastic filaments. This means that neuropathic pain was remarkably induced in the central neuropathic animal model prepared in the present invention.

After confirming that pain is induced in the central neuropathic animal model of the present invention, the analgesic effect of ginsenoside and ginseng-derived saponin extract according to the present invention was confirmed. As a result, as shown in FIG. 2B, the ginseng-derived saponin extract showed analgesic effect when administered repeatedly for 3 days, while Rb1 and Compound K showed analgesic effect gradually as treatment was repeated. On the third day, the last day of administration, the best effect was obtained. Rg3 began to suppress neuropathic pain from day 3 of oral administration (FIG. 2B). A positive control, minocycline, showed a significant analgesic effect by treating 22.5 mg twice a day and reducing pain response to mechanical stimulation for three days.

<1-3> columns Of heat hyperalgesia  Measure

The present inventors measured pain change with respect to temperature stimulation to determine whether the pain behavior of ginsenosides Rb1 and Rg3, Compound K, or ginseng-derived saponin extract was reduced or alleviated.

Thermal susceptibility was assessed using the plantar inspection device as described by Hargreaves et al. (1988). Central neuropathic pain animal models on glass plates were acclimated for at least 20 minutes in an acrylic box. Under the glass plate, a device with a laser beam that can be moved to fit the surface of the animal's paws. The heat intensity of the light was adjusted by obtaining an average foot avoidance latency of about 15 seconds and the time limit set to 20 seconds to prevent tissue damage. Three thermal stimuli were given to both feet at 5-10 minute intervals. The average of the foot avoidance incubation times of each foot attempted three times indicated the degree of foot avoidance.

In the central neuropathic pain animal model according to the present invention, the pain-induced hypersensitivity test was performed. As shown in FIG. 2C, 4 weeks after the preparation of the central neuropathic animal model according to the present invention was performed. After lapse, when the ginsenoside Rb1, Rg3, and Compound K, or ginseng-derived saponin extract according to the present invention was not administered, the soles of the central neuropathic pain animal model were irritated with heat beams for 6.4 seconds. Confirmed that the wig was raised. This means that neuropathic pain was remarkably induced in the central neuropathic animal model prepared in the present invention.

After confirming that pain is induced in the central neuropathic animal model of the present invention, the analgesic effect of ginsenoside and ginseng-derived saponin extract according to the present invention was confirmed. As shown in FIG. 2C, the ginseng-derived saponin extract showed analgesic effect when administered repeatedly for 3 days, while Rb1 and Compound K showed analgesic effect gradually as treatment was repeated. The best effect was seen on day 3 of the day. Rg3 began to suppress neuropathic pain from day 3 of oral administration (FIG. 2C).

A positive control, minocycline, had a significant analgesic effect by treating twice a day and reducing pain response to thermal stimulation for three days.

In addition, as shown in FIG. 2D, when the ginseng-derived saponin extract and the single compound according to the present invention were administered, respectively, BBB values, mechanical allodynia, and heat hyperalgesia were measured. For BBB levels, no differences were found in all experimental groups (negative and positive controls, ginseng-derived saponin extracts, Rb1, Rg3, and Compound K), but for mechanical allodynia, Ginsenoside Rb1, and Compound K were administered. Similar to the minocycline used as a positive control group, the effect of significantly inhibiting the pain was observed compared to the control group. In case of heat hyperalgesia, the effect of significantly inhibiting pain was observed similarly to minocycline, in which Rb1 and Compound K were positive controls (FIG. 2D).

< Experimental Example  2> Ginseng  Depending on Saponin Extract Concentration Neuropathic  Confirmation of pain inhibitory effect

The present inventors, 20, 50, 100, 200 ㎍ the ginseng-derived saponin extract in the central neuropathic pain animal model prepared in Example 4 to determine the pain inhibitory effect according to the concentration of the ginseng-derived saponin extract After each administration intraperitoneally, the inhibitory effect of pain was observed for 4 hours.

As a result, as shown in FIG. 3A, when the ginseng-derived saponin extract 20, 50, 100, and 200 μg were administered into the spinal cord in the "pre" state 4 weeks after the preparation of the central neuropathic animal model, The analgesic effect on mechanical allodynia showed a concentration-dependent analgesic effect at concentrations of 100 μg and 200 μg (FIG. 3A).

In addition, as shown in B of FIG. 3, the heat hyperalgesia test showed the effect at 1 hour after administration only at a concentration of 200 μg (FIG. 3B).

In addition, when ginseng-derived saponin extract from 20 μg to 200 μg of high concentration was injected into the spinal cavity, the experimental animals exhibited no movement and no movement or sedation. Therefore, it was found that there was no effect of toxicity due to the high concentration of saponin extract.

< Experimental Example  3> The backbone of estrogen antagonists Neuropathic  Pain reduction inhibitory effect

After confirming the experimental results of the single injection of ginsenoside Rb1, Compound K and ginseng-derived saponin extract, the present inventors determined that the estrogen antagonist ICI 180782, a central neuropathic pain animal model, to determine whether their analgesic action is related to the estrogen receptor. Was administered once into the spinal cord.

First, after 4 weeks of preparing the central neuropathic pain animal model of <Example 4>, ginseng-derived saponin extract (200 μg / 10 μl) within the subarachnoid membrane between the lumbar vertebrae 5 to 6 The effect of single injection with Rb1 (50 μg / 10 μl), respectively, and co-administration with estrogen antagonist ICI (50 μg / 10 μl) and ginseng derived saponin extract or Rb1 Learned the relevance of

As shown in Figure 4, the result of testing the mechanical allodynia (mechanical allodynia), after administration of ginseng-derived saponin extract or ginsenoside Rb1 according to the present invention, respectively, when observed for 1 hour to 4 hours, administration 1 hour The most powerful analgesic effect was observed, which showed statistical significance (p <0.05). When the estrogen antagonist was administered with ginseng-derived saponin extract or ginsenoside Rb1, no analgesic effect was observed (A and B of FIG. 4).

In addition, as a result of examining the heat hyperalgesia, after administration of ginseng-derived saponin extract or ginsenoside Rb1 according to the present invention, respectively, for 1 to 4 hours, the most powerful analgesic after 1 hour of administration An effect was observed, which showed statistical significance (p <0.05). However, when the estrogen antagonist was administered with ginseng-derived saponin extract or Rb1, no analgesic effect was observed. Therefore, as a result of observing the pain response to the mechanical and thermal stimulation, it can be seen that ginseng-derived saponin extract and ginsenoside Rb1 mediate the pain effect through the estrogen receptor.

< Experimental Example  4> Gin Senocide Rb1  And Rg3 , Compound  K, or Ginseng  Inhibitory Effect of Saponin Extract on Inflammatory Pain

In order to measure the inflammatory pain inhibitory effect of ginsenosides Rb1 and Rg3, Compound K, or ginseng-derived saponin extracts, the present inventors injected adult male rats (weight 200-250) with 50 μl of 5% formalin solution subcutaneously. g) was used.

Specifically, the ginsenosides Rb1 and Rg3, Compound K, or ginseng-derived saponin extracts of the present invention were injected 30 minutes prior to formalin injection, and then formalin solution was injected into the instep of adult male rats. The licking time or the lifting time was measured. Ginseng-derived saponin extracts contained 200 μg / rat (n = 4), Rb1 50 μg / rat (n = 3), Rg3 50 μg / rat (n = 3), Compound K 50 μg / rat (n = 4) Into the spinal cord. The control group was administered only saline without saponin extract (n = 8). After 30 minutes, as soon as the formalin solution was injected, the lifting duration and the licking duration were measured at 5 minute intervals for 1 hour after being placed in a transparent acrylic box.

In the untreated group, only formalin was injected subcutaneously without medication, and painful behavior was measured immediately after infusion. Pain behavioral response was measured in the same manner as in the measurement of mechanical allodynia and hyperalgesia described in <Example 1>.

As a result, as shown in Figure 5, between 0 ~ 10 minutes after the formalin administration (Early phase) was not significant between the groups, between 10 to 60 minutes (Late phase) when the inflammatory response (gatenoside Rb1 and Rg3 It was confirmed that the experimental group administered with saponin extract, Compound K, or ginseng derived from each group showed statistically significant (p <0.05) inflammatory pain inhibitory effect compared to the control group. Inflammation response time in the experimental group was reduced to less than 50% of ginseng-derived saponin extract, less than 7% of Rb1, less than 30% of Rg3, and less than 20% of Compound K. These results indicate that ginseng-derived saponin extracts and ginsenosides Rb1 and Rg3, Compound K isolated therefrom inhibit inflammatory pain as well as neuropathic pain (FIG. 5).

< Experimental Example  5> Gin Senocide Rb1  And Rg3 , Compound  K, or Ginseng  Micronerve of Saponin Extract Glial  Inhibitory effect

Ginseng-derived saponins in central neuropathic animal models according to the present invention Ginsenoside-derived saponin extract (50 mg / kg, n = 4) and ginsenosides isolated from the extract to determine the inhibitory effect of microglial cells on lamina I, II (lumbar 4) Rb1 (11.5 mg / kg, n = 4), Rg3 (11.5 mg / kg, n = 4), and Compound K (7 mg / kg, n = 4) were dissolved in tertiary distilled water, respectively, to the experimental animals 3 times a day. After oral administration for 1 day, 1 hour after oral administration on the last 3 days, tissues were obtained and subjected to immunohistochemical staining. The negative control group was orally administered 1 ml of saline once a day for 3 days (n = 4), and the positive control group was administered minocycline twice a day by intraperitoneal injection at a dose of 22.5 mg / kg for 3 days (n = 4).

Antibody-antibody reaction was performed with OX-42, a marker of microglial cells, to compare the number of activated microglial cells in the experimental and control groups.

Ginsenosides Rb1 and Rg3, Compound K, ginseng-derived saponin extract, vehicle, and minocycline according to the present invention one hour after the last day of drug administration, sodium pentobarbital (50 mg / kg) intraperitoneally After anesthesia by injection, 0.9% physiological saline solution was perfused through the left ventricle through the aorta to wash blood in the blood vessels, and then perfusion-fixed with 0.1 mol of phosphate buffer containing 4% paraformaldehyde. After spinal nerve 4 spinal nerves were removed, the tissues were postfixed in fixative solution for 2 hours, and then immersed in 30% sucrose solution at 4 ° C for 2-3 days until the tissues settle down. It was. The extracted tissue was cut into 10 mm using a frozen slicer, and then attached to a slide coated with gelatin and stored frozen until use.

Spinal cord slices cut to 10 mm thickness were subjected to immunohistochemical staining by ABC (Avidin-biotin-peroxidase complex) method using an antibody against OX-42, a microglial cell marker (Hsu et al., 1981). In order to increase the permeability of the tissue all reactions are carried out in 0.05 molar phosphate buffer (PBS-Tx) containing 0.3% Triton X-100. Tissue sections were reacted in PBS-Tx solution containing 10% normal goat serum (NGS) and 1% bovine serum albumin (BSA) for 1 and a half hours to prevent non-specific antigen-antibody reactions. , And reacted with OX-42, GFAP (Chemicon, USA) primary antibody diluted at 4 ° C for 24 hours (dilution determined during the experiment). The tissue sections were washed three times for 10 minutes with 0.05M PBS-Tx, and then immersed in a secondary antibody solution (biotinylated goat anti-mouse IgG) diluted 1: 200 and reacted at room temperature for 2 hours. Again washed three times with PBS-Tx for 10 minutes and reacted with ABC solution for 2 hours at room temperature. Wash three times with phosphate buffer three times for 10 minutes, and develop a color reaction at room temperature for 5 to 10 minutes (adjust the time while continuing to observe) in phosphate buffer containing 0.01% hydrogen peroxide and 0.05% DAB. After washing three times with phosphate buffer solution three times for 10 minutes, and then three times for 5 minutes in tertiary distilled water, dehydrated with ethyl alcohol and xylene in increasing order and put on a cover glass through a transparent process. Made into a sample.

The degree of expression of glial cells of the spinal cord olfactory cells was divided into the activated or restoring state of immunostained cells and counted and compared.

The expression level of OX-42 was analyzed by comparing the digital image of the spinal cord obtained through the microscope with the control software (Scion image, Scion Corp. USA).

As a result, as shown in FIG. 6A, the number of activated microglial cells was minocycline (minocycline) used as a positive control in a group administered with ginsenoside Rb1 and Rg3, Compound K, or ginseng derived saponin extract, respectively. It was confirmed that the decrease by the group administered. In particular, the group administered with Rb1, Compound K was confirmed that the number of activated microglial cells more significantly reduced than the group administered with minocycline (A of FIG. 6).

In addition, when counting the activated or inactivated microglial cells through the staining results, the number of activated microglial cells in the group administered with minocycline used as a positive control group decreased compared with the group administered with saline used as a negative control group. This trend was attributed to the administration of ginsenosides Rb1 and Rg3, Compound K, or ginseng-derived saponin extracts, respectively. All were observed in the group. Among them, in particular, the group administered with ginsenoside Rb1 and Compound K showed a result of reducing the activity of microglial cells more effectively than minocycline (Fig. 6B). These results indicate that activated microglial cells in the spinal cord smell increase pain (Hains and Waxman, 2006 Detloff et al., 2008 Hulsebosch, 2008; Tan et al., 2009), which are isolated from ginseng-derived saponin extracts. Ginsenosides Rb1, Rg3 and Compound K means that inhibit the pain by preventing the activation of microglial cells (Fig. 6).
