Abstract
Description
Technical Field
[0001] The present invention belongs to the field of traditional Chinese medicine preparations and relates to a pharmaceutical composition and use thereof. Background Art
[0002] Bawei Chenxiang Wan is a water-based pill made from the classic Tibetan medicine Bawei Chenxiang Powder. The recipe dates back to the 8th century and was first recorded in the classic Tibetan medical treatise, the Four Medical Classics. It is now included in the first volume of the Ministry of Health's Drug Standards for Tibetan medicine. It is composed of the botanicals nutmeg, agarwood, jujube, frankincense, terminalia chebula, costus root, and kapok, and the mineral travertine. It clears heart heat and calms the mind, and is used for fever-related heart attacks and precordial pain. It can also open the mind and soothe the nerves, and is used to treat coma and delirium. Bawei Chenxiang Powder, included in the 2020 edition of the Chinese Pharmacopoeia, shares its ingredients but uses different dosages.
[0003] As a commonly used drug in Tibetan areas for the treatment of cardiovascular disease and associated insomnia, Bawei Chenxiang Wan (Eight Flavors Agarwood Pill) has demonstrated clinical efficacy. However, current basic research on the chemistry and pharmacology of Bawei Chenxiang Wan is relatively weak, limiting its further development and application. This is particularly evident in the single formulation and lack of quality standards for Bawei Chenxiang Wan, necessitating an urgent need for further basic research. This study designed and screened the optimal extraction route for the drug. The extracts obtained from three extraction routes were compared for their anti-myocardial ischemia and anti-insomnia effects, preliminarily exploring their anti-insomnia mechanism of action. Chromatographic analysis was also used to analyze the differences in chemical composition among the different extracts, laying the foundation for subsequent research on the active ingredients of Bawei Chenxiang Wan, improving quality standards, and developing dosage forms.

[0124] Example 3: Evaluation of anti-myocardial ischemic effect
[0125] Normal male ICR mice were anesthetized with an intraperitoneal injection of sodium pentobarbital in saline (50 mg / kg mouse body weight). The skin on the chest was prepared and the animals were connected to a ventilator. After thoracotomy, the left anterior descending coronary artery (LAD) was visualized. The LAD was ligated with a sterile suture needle and the chest was closed with sutures to create an acute myocardial ischemia (AMI) mouse model. Sixty mice were treated.
[0126] (1) Sham group: 10 mice in total were treated with suture threading at the same position as the model group mice, but without ligation. Other procedures were the same. No medication was given.
[0127] 24 hours after modeling, the mice in the model group were randomly divided into the following six groups:
[0128] (2) Model group (Mod group), no drug administration;
[0129] (3) Water extraction group (ST group), using ST obtained in Example 1, with a dose of 760 mg powder / kg mouse body weight);
[0130] (4) Alcohol extraction group (CT group), using the CT obtained in Example 1, with a dose of 620 mg powder / kg mouse body weight);
[0131] (5) Alcohol extraction followed by water extraction group (SCT group), using the CST obtained in Example 1 at a dose of 1040 mg powder / kg mouse body weight);
[0132] (6) Positive drug fosinopril group (Group F), using fosinopril at a dose of 10 mg drug / kg mouse body weight;
[0133] (7) Bawei Chenxiang Wan original drug group (W group), using the Bawei Chenxiang Wan selected in Example 1, with a dose of 3000 mg powder / kg mouse body weight);
[0134] The drugs were dissolved in water and administered orally to 10 mice in each of the 7 groups for 7 consecutive days, once at the same time every day.
[0135] After 7 days, echocardiography was used to detect and calculate the ejection fraction (EF), fractional shortening (FS), left ventricular end-diastolic diameter (LVED; d), and left ventricular end-systolic diameter (LVED; s) of the mice in each group; and heart tissues were collected for HE staining to examine the myocardial tissue pathology.
[0136] The statistical data on the effects of different drugs on cardiac function in AMI mice can be found in Figure 1 , compared with the Sham group, ## P<0.01, ### P<0.001; compared with the Mod group, *P<0.05, **P<0.01, ***P<0.001.
[0137] Representative echocardiograms of 7 groups of AMI mice are shown in Figure 2-Figure 8 In each figure, the upper image shows the short-axis papillary muscle section of the heart, and the lower image shows the fluctuations of the anterior and posterior walls of this section.
[0138] The ultrasound results on the 8th day after surgery showed that compared with the sham operation group, the LVID;d and LVID;s of the model group mice were significantly increased (P<0.001), and the EF and FS values were significantly decreased (P<0.001), indicating that the left ventricular anterior wall was thinned, the ventricle was dilated, and the left ventricular systolic and diastolic functions were impaired, indicating that the myocardial infarction model was successfully established. Compared with the model group, the positive drug fosinopril group (F) could significantly increase EF (P<0.01) and reduce LVID;d and LVID;s values (P<0.05, P<0.01); the Baweichenxiang pill group (W) could significantly increase EF and FS values (P<0.001, P<0.01) and reduce LVID;d and LVID;s values (P<0.001); the alcohol extract group (CT) could significantly increase EF and FS (P<0 .001, P<0.01), and reduced LVID;d and LVID;s values (P<0.01, P<0.001). The alcohol-extracted water extract group (CST) significantly increased EF and FS (P<0.001, P<0.05) and reduced LVID;d and LVID;s values (P<0.01, P<0.001). The water extract group (ST) increased EF and FS and reduced LVID;d and LVID;s values. Ultrasound results suggested that both the CT and CST groups had significant anti-myocardial ischemic effects.
[0139] HE staining photos of the seven groups are shown as follows Figure 9-15As shown, HE-stained sections of myocardial tissue were observed under an optical microscope at 12.5 times (see the small picture in the upper left corner) and 400 times (see the large picture). In the sham-operated group, myocardial cells were intact and arranged neatly, with clear myocardial cell striations and no obvious inflammatory cell infiltration. In the model group, obvious myocardial cell arrangement disorder was observed, with a large number of inflammatory cells infiltrating in the tissue and some myocardial cells degenerating. After administration of F, W, CT, and CST, it was observed that inflammatory cell infiltration was reduced and the degree of myocardial cell disorder was improved.
[0140] Example 4: Experiment on the effect of drugs on mouse sleep
[0141] 1. Evaluation of sleep-aiding effects in mice
[0142] Mouse grouping:
[0143] (1) Normal group (Con group), normal male ICR mice, no modeling, no drug administration, 10 mice;
[0144] Normal male ICR mice were intraperitoneally injected with 4-chloro-DL-phenylalanine (PCPA) in saline at a dose of 500 mg / kg mouse body weight for five consecutive days, with daily injections. The mice were observed for a successful PCPA insomnia model. Loss of circadian rhythm, dull fur, and slow weight gain were observed. Successful models were randomly divided into six groups of 10 mice each. Dosing began the day after model establishment.
[0145] (2) Model group (Mod group), no drug was given.
[0146] (3) positive drug diazepam group (DZP group), the dose was 1.5 mg drug / kg mouse body weight;
[0147] (4) Bawei Chenxiang Wan original drug group (W group), using the Bawei Chenxiang Wan selected in Example 1, with a dose of 3000 mg powder / kg mouse body weight;
[0148] (5) Water extraction group (ST group): ST obtained in Example 1 was used at a dose of 760 mg powder / kg mouse body weight;
[0149] (6) Alcohol extraction group: CT obtained in Example 1 was used at a dose of 620 mg of powder / kg of mouse body weight;
[0150] (7) Alcohol extraction followed by water extraction group (SCT group): CST obtained in Example 1 was used at a dose of 1084 mg powder / kg mouse body weight;
[0151] Each group had 10 mice, and the drugs were administered orally for 7 consecutive days, once a day. One hour after the last oral administration, the sleep-inducing effects of the three extracts were evaluated by oral administration of sodium pentobarbital saline solution (50 mg drug / kg mouse body weight). The sleep latency and sleep maintenance time of the mice were recorded.
[0152] 2. GAD67 protein expression in mouse brain tissue
[0153] For each group of mice, after sodium pentobarbital anesthesia, brain tissue from each group of mice was obtained and stored in an ultra-low temperature freezer at -80°C. About 10 mg of brain tissue was minced and placed in a centrifuge tube. RIPA lysis buffer and a protein phosphatase inhibitor cocktail (100:1 volume ratio) were added at 100 mg / mL. After adding one steel ball, a tissue disruptor was used at 30 times / s. After oscillation and disruption for 3 minutes, the tissue was centrifuged at 12,000 rpm at 4°C for 10 minutes, and the tissue homogenate supernatant was obtained. The protein content of the sample was determined according to the BCA assay kit instructions, with a quantification of 4 μg / μL. Loading buffer was added, and the cells were denatured at 95°C for 10 minutes. The cells were then stored at -20°C until further use. Equal amounts of protein were loaded and separated by SDS-PAGE. The proteins were then transferred to PVDF membranes and blocked with 5% skim milk for 2 h. Specific antibodies against GAD67 and GAPDH proteins were added, respectively. The membranes were incubated overnight at 4°C, washed with TBST five times for 5 min each time, incubated with goat anti-mouse secondary antibody at room temperature for 2 h, washed with TBST five times for 5 min each time, and developed with enhanced chemiluminescence (ECL). Grayscale analysis was performed using ImageJ software. The protein level was expressed as the ratio of GAD67 expression in the cortical tissue of each group to the internal control GAPDH expression.
[0154] The results are as follows Figure 16As shown in the data, compared with the normal group, the sleep latency of mice in the model group was significantly prolonged (P<0.01) and the sleep duration was significantly shortened (P<0.001), indicating that the PCPA insomnia mouse model was successfully established. Compared with the model group, the diazepam group (DZP) significantly shortened the sleep latency of mice (P<0.001) and prolonged the sleep duration of mice (P<0.001). The Bawei Chenxiang Pill group (W) did not shorten the sleep latency of mice (P>0.05), but significantly prolonged the sleep duration of mice (P<0.01). The CT group significantly shortened the sleep latency of mice (P<0.001) and prolonged the sleep duration of mice (P<0.01). The ST group significantly prolonged the sleep duration of mice (P<0.001). Both the CT and ST groups had significant sleep-inducing effects. In terms of protein expression, compared with the blank group, the GAD67 protein expression level in the cortical tissue of mice in the PCPA model group was significantly decreased; compared with the model group, after ST, CT, and W intervention, the expression of GAD67 protein was significantly increased (P<0.001), indicating that ST, CT, and W exert a sleep-inducing effect by upregulating the protein expression of GAD67.
[0155] These results demonstrate that CT and CST exhibit clear anti-myocardial ischemic effects, while ST and CT exhibit clear sleep-inducing effects. Furthermore, CT exhibits a more pronounced anti-myocardial ischemic effect, while ST exhibits a more pronounced sleep-inducing effect. These results suggest that extracts obtained by different extraction methods exhibit distinct differences in efficacy, and that the anti-AMI and sleep-inducing effects may be contributed by distinct pharmacological substances. Further comparative chemical composition studies of the different extracts identified 17 major chemical components in ST, 25 major chemical components in CT, and 27 major chemical components in CST. Furthermore, the sleep-inducing effect of ST is associated with increased expression of GAD67, a key enzyme required for GABA synthesis, providing guidance for further mechanistic studies.
[0156] Tibetan medicine theory posits that heart disease is primarily caused by internal and external factors, such as emotional disharmony, melancholy and depression, irritability and insomnia, anger and resentment, as well as eating disorders and excessive hunger. Symptoms include restlessness, stabbing pain, and heart heat. Tibetan medicine integrates cardiac physiology with the mind and psychology, similar to the traditional Chinese medicine concept that "the heart governs the spirit." Bawei Chenxiang Wan, a commonly used Tibetan medicine treatment for heart disease and associated insomnia, has the potential to treat both the heart and the brain. Therefore, this study comprehensively evaluated the efficacy of the drug in a mouse model of acute myocardial ischemia induced by ligation of the left anterior descending coronary artery and a mouse model of insomnia induced by intraperitoneal injection of para-chlorophenylalanine, providing insights for further exploring the potential of this "heart-brain" approach.
[0157] This study used intraperitoneal injection of PCPA to establish a mouse model of insomnia. PCPA blocks 5-hydroxytryptamine synthesis by inhibiting tryptophan hydroxylation. Serotonin deficiency leads to a decrease in the number of inhibitory neurotransmitter GABAergic neurons, their synapses, and clusters, thus inducing insomnia. GAD67 protein is involved in regulating GABA synthesis. Previous studies on the mechanisms of Bawei Chenxiang Wan revealed that GAD67 protein was highly expressed in the Bawei Chenxiang Wan-treated group, so this protein was selected for preliminary exploration of the sleep-inducing mechanisms of different Bawei Chenxiang Wan extracts. Further systematic research is needed to elucidate the in-depth sleep-inducing mechanisms, anti-myocardial ischemic mechanisms, and the combined mechanisms of sleep-inducing and anti-myocardial ischemic effects of different Bawei Chenxiang Wan extracts. This will clarify the rich connotations of Bawei Chenxiang Wan's "heart-brain treatment" and the multi-component, multi-mechanistic characteristics of the compound.
[0158] The original formulation of Bawei Chenxiang Wan (Bawei Chenxiang Wan) was prepared from the raw powder of the medicinal material. To investigate the changes in efficacy after extraction compared to the original formulation, the mouse dosage calculated from the clinically effective dose of Bawei Chenxiang Wan (3g / 70kg) was used as the raw material dosage. The dosages of the three extracts were calculated based on the extraction rate. Since the mineral travertine cannot be extracted by organic solvents, the three extracts were converted to plant extracts based on the extraction rate of the botanical drug. These extracts were then combined with the travertine at the original dosage of the formulation. The resulting dosages were: Bawei Chenxiang Wan (3000mg / kg), ethanol extract (620mg / kg), water extract (760mg / kg), and ethanol-water extract (1084mg / kg).
[0159] Comparing the efficacy of different extracts allows for optimal extraction routes to be identified. Comparing their components allows for a valuable exploration of the drug's active ingredients. Alcohol and water extracts differ significantly in polarity distribution, naturally leading to differences in their efficacy. For example, in this study, Bawei Chenxiang Wan's CT exhibited a predominance of anti-myocardial ischemia effects, while ST exhibited a sleep-inducing effect. Furthermore, attempts were made to combine alcohol and water extractions to achieve a more comprehensive extract composition, aiming to achieve an ideal combination of efficacy.
[0160] Based on the indications of Bawei Chenxiang Wan, this study clarified the pharmacological advantages of three extraction routes using a dual pharmacodynamic evaluation system in mouse models of acute myocardial ischemia and insomnia. Component analysis results suggest that chromones and terpenoids primarily contribute to the anti-ischemic effect, while tannins and phenolic acids primarily contribute to the sleep-inducing effect. Furthermore, this sleep-inducing effect is associated with regulating GAD67 protein expression. These results provide a scientific basis for elucidating the pharmacological components of Bawei Chenxiang Wan, establishing quality standards, and rationalizing its clinical use, laying a solid foundation.
