Description

Technical Field

[0001] This invention relates to the pharmaceutical field, and specifically to a pharmaceutical composition and its use. Background Technology

[0002] Phenylketonuria (PKU) is a common disorder caused by the metabolism of the aromatic amino acid phenylalanine. It is an autosomal recessive genetic disorder caused by a gene defect that results in a deficiency of phenylalanine hydroxylase (PAH) or its coenzyme tetrahydrobiopterin (BH4), leading to hyperphenylalaninemia (HPA). The accumulated phenylalanine and its intermediate metabolites damage the central nervous system, and if left untreated, it can lead to irreversible intellectual disability, mental and behavioral abnormalities, and other symptoms.

[0003] There is currently no cure for phenylketonuria (PKU). Management primarily involves medication combined with dietary control. Some commonly used medications include: Sapropterin Dihydrochloride, an oral synthetic form of tetrahydrobiopterin (BH4), which activates residual phenylalanine hydroxylase activity, helping to metabolize phenylalanine and lowering serum phenylalanine levels. It is suitable for PKU patients who respond to BH4 (approximately 10%-20% of patients). Suitability needs to be confirmed through genetic testing or a BH4 loading test. During treatment, regular monitoring of serum phenylalanine levels, liver function, and neurological symptoms is necessary. Adverse reactions such as headache and diarrhea may occur. Pegvaliase is a recombinant phenylalanine ammonia-lyase that converts phenylalanine into harmless metabolites, directly lowering blood phenylalanine levels. It is independent of phenylalanine hydroxylase activity and is primarily used in adult patients with PKU, especially those whose blood phenylalanine levels cannot be effectively managed through diet and sapropterin. Subcutaneous injection may cause injection site reactions and allergic symptoms; a skin allergy test is required before use, and blood phenylalanine levels and antibody production should be monitored during treatment. Sephience (Sepiapterin), as a prodrug of BH4, increases phenylalanine hydroxylase activity and lowers blood phenylalanine levels through a dual mechanism of action. Adverse reactions may include upper respiratory tract infection (19.8%), headache (15.3%), diarrhea (14.9%), abdominal pain (12.2%), and abnormal stool color (4.5%). Regular monitoring of blood phenylalanine concentration and nutritional status is necessary.

[0004] Therefore, it is necessary to develop a pharmaceutical composition for treating phenylketonuria with low adverse reactions. Summary of the Invention

In some embodiments, the ovarian insufficiency includes premature ovarian failure.

[0039] Phenylketonuria (PKU) is an autosomal recessive inherited amino acid metabolism disorder and one of the most common genetic diseases detected in newborn screening. Its core characteristic is a deficiency of a key enzyme that breaks down phenylalanine, leading to the accumulation of phenylalanine and its metabolites in the body. This causes irreversible damage to the nervous system, and without timely intervention, it can result in serious consequences such as intellectual disability and developmental delays. Early diagnosis and standardized treatment can significantly improve patient prognosis, reduce the harm caused by the disease, and help patients achieve a normal life.

[0040] The pharmaceutical compositions and formulations provided by this invention have good therapeutic effects on phenylketonuria, while exhibiting fewer gastrointestinal side effects. The pharmaceutical compositions and formulations provided by this invention also have good anti-inflammatory therapeutic effects.

[0041] The compositions described in this invention are compositions for the prevention and / or treatment of pyketonuria, and / or compositions for reducing gastrointestinal adverse reactions, and / or compositions for the prevention or treatment of nephritis, and / or compositions for the prevention and / or treatment of ovarian insufficiency.

[0042] The pharmaceutical preparations described in this invention are pharmaceutical preparations for the prevention and / or treatment of pyketonuria, and / or pharmaceutical preparations for reducing gastrointestinal adverse reactions, and / or pharmaceutical preparations for the prevention or treatment of nephritis, and / or pharmaceutical preparations for the prevention and / or treatment of ovarian insufficiency.

[0043] The structural formulas of adenosine, uridine, and hibifolin (also known as gossypol-8-O-β-D-glucuronide) described in this invention are as follows:

[0044] The term "treatment" as used in this invention generally refers to achieving a desired pharmacological and / or physiological effect. The effect may be preventative, but not necessarily preventative, in relation to the prevention or partial prevention of a disease, symptom, or condition (such as dermatitis). The effect may be therapeutic in relation to the partial or complete cure of a disease, condition, symptom, or adverse reaction attributable to that disease, condition, or condition. Specifically, the term "treatment" can include any treatment of a subject (especially a person) for a relevant symptom or disease, and may include any one or more of the following: (a) preventing the disease from occurring in subjects who may be susceptible to the disease but have not yet been diagnosed with it; (b) suppressing the disease, i.e., preventing its development; and (c) alleviating the disease, i.e., reducing or improving the disease and / or its symptoms or condition. The term "pharmaceutically acceptable" refers to a substance that does not significantly affect the biological activity of the pharmaceutical composition of the present invention at that dosage. The term "pharmaceuticalally acceptable carrier" refers to a substance that does not significantly affect the biological activity of the pharmaceutical composition of the present invention at that dosage, particularly the biological activities listed in the experiments of the embodiments of this application. The pharmaceutically acceptable carrier may be selected from disintegrants such as sodium carboxymethyl starch, crospovidone, and sodium crospovidone carboxymethyl cellulose; fillers such as starch, lactose, microcrystalline cellulose, asiaticoside (an extract obtained by reflux extraction of Centella asiatica with 90% ethanol and subsequent drying), mannitol, and sucrose; binders such as PVP, hydroxypropyl methylcellulose (HPMC), and starch paste; lubricants / flow aids such as magnesium stearate and talc; and coating materials such as acrylic resin and gastric / enteric coating materials. These carriers may be one or more combinations thereof. Preferably, these carriers meet the quality standards for pharmaceutical excipients, for example, pharmaceutical excipients registered with the National Medical Products Administration. The pharmaceutical compositions and formulations of the present invention have biological activities including prevention and / or treatment of phenylketonuria, anti-inflammatory effects, and low gastrointestinal adverse reactions. In addition, preliminary exploratory experiments have shown that they have good preventive and / or therapeutic effects on ovarian insufficiency, especially good preventive and / or therapeutic effects on premature ovarian failure.

[0045] Premature ovarian insufficiency (POI) refers to a syndrome of decreased ovarian function that occurs in women before the age of 40. Clinical manifestations include infrequent, frequent, or absent menstruation for at least 4 months. Laboratory tests show two basal FSH (follicle-stimulating hormone) levels >25 U / L at intervals of more than 4 weeks, and fluctuating estrogen levels. The incidence of this disease is about 1% to 4%, and it is divided into primary POI, which is the absence of spontaneous menstruation, and secondary POI, which is the decline in function after the occurrence of normal menstruation. The previously referred to premature ovarian failure (POF) is the terminal stage of POI, specifically referring to a state of amenorrhea for more than 4 to 6 months before the age of 40, FSH >40 U / L, persistently low estrogen levels, and menopausal symptoms.

[0046] The contents of the active ingredients sibifluin, uridine, and adenosine contained in the pharmaceutical composition or pharmaceutical preparation of the present invention can be detected by conventional high performance liquid chromatography (HPLC) methods, and they have separation effects that meet the requirements of the pharmacopoeia, such as good resolution.

[0047] Specifically, the determination was performed according to high performance liquid chromatography (HPLC) (Chinese Pharmacopoeia 2020 Edition, Part IV, General Chapter 0512). The detection method for sibiformin (HPLC Method A) is as follows: using octadecylsilane-bonded silica gel as the stationary phase (Agilent ZORBAX SB C18 column, 250 × 4.6 mm, 5 μm), accurately pipette 10 μl each of the reference solution and the test solution and inject them into the HPLC system. Acetonitrile was used as mobile phase A, and 0.1% phosphoric acid solution was used as mobile phase B. Gradient elution was performed (0–20 min, 6% A → 17% A; 20–30 min, 17% A → 17% A; 30–50 min, 6% A → 17% A; 30–50 min, 17% A → 17% A). The chromatography was performed at a wavelength of 360 nm, a flow rate of 1.0 mL / min, and a column temperature of 30 °C. The chromatogram was recorded, and the content of Sibiforin was calculated by peak area using the external standard method with a correction factor of 1.09. The relative retention time of the analyte Sibiforin peak and the hyperoside reference standard peak was within 1.361 ± 5%. The reference standard solution was prepared by accurately weighing an appropriate amount of hyperoside reference standard and adding 70% ethanol to prepare a solution containing approximately 0.2 mg per mL. The test solution was prepared by accurately weighing an appropriate amount of sample (50 mg), placing it in a 50 mL volumetric flask, adding an appropriate amount of 70% ethanol, sonicating for 20 minutes, cooling, diluting to the mark with 70% ethanol, shaking well, filtering, and collecting the filtrate. The detection method for uridine and adenosine (HPLC method B) is as follows: A C18 column AQ-C18 (4.6 × 250 mm, 5 μm) is used with 0.1% formic acid solution (A) - acetonitrile (B) as the mobile phase. The detection wavelength is 260 nm, the flow rate is 1.0 mL / min, the column temperature is 30℃, and the signal acquisition time is 0 min to 12 min. Elution is performed (0~12 min, 2% B; 12~15 min, 2% B → 95% B). The sample is prepared by accurately weighing approximately 0.5 g of the sample, placing it in a 50 mL volumetric flask, adding 35 mL of 10% methanol, sonicating for 20 minutes, cooling, adding 10% methanol to the mark, and shaking well. The adenosine content is determined by external standard method, and the uridine content is calculated using the relative correction factor (correction factor is 1.32) with adenosine. The relative retention time of the uridine peak and the adenosine reference peak is within 0.808 ± 5%. The mass ratio in the pharmaceutical composition is calculated directly from the content data obtained by the detection method.

[0086] Test Example 2: The therapeutic effects of different drug combinations on phenylketonuria 1. Test substance and grouping Control model group.

[0087] Dosing Example Group: Pharmaceutical compositions prepared using the methods of Examples 1, 2, 3, and 8; Comparative control group: Drug compositions prepared using the methods of Comparative Examples 1 and 2; Except for the control model group, the dosage of each administration example group and the administration comparison group was 70 mg / kg based on the total mass of sibifluin, uridine and adenosine, and the administration method was gavage.

[0088] 2. Experimental animals Pah enu2 Forty-two mice (phenylketonuria model mice, Jackson Laboratory, USA), half male and half female, weighing 20±2g, were used. They were acclimatized for 3 days at a room temperature of 23±2℃ with alternating light and dark lighting for 12 hours, and were provided with regular feed and access to drinking water. After 3 days of feeding, blood was collected from the tail vein to measure the phenylalanine content in the blood, which was used as the pre-administration phenylalanine concentration.

[0089] The model mice were randomly divided into 7 groups, with 6 mice in each group, half male and half female. The drug administration example groups were fed the drug compositions prepared according to methods 1, 2, 3, and 8, respectively, along with a conventional diet. The drug administration control example groups were fed the drug compositions prepared according to methods 1 and 2, respectively, along with a conventional diet. The control model group was fed a conventional diet. Each feeding consisted of 6g of feed, along with 5mL of drinking water, for 14 consecutive days. Blood was collected from the tail vein on day 14 after drug administration to detect the phenylalanine content in the serum, which was used as the post-drug administration phenylalanine concentration. The results are shown in Table 4 below.

[0090] Table 4. Effects of different drug combinations on Pah enu2 Effect of phenylalanine concentration in mouse blood

[0091] Note: ## P <0.01, compared with the control group.

[0092] Experimental results showed that the drug administration examples all significantly reduced the concentration of phenylalanine. Although the drug administration comparison groups also showed a reducing effect, their reducing effect was not as good as that of the drug administration examples.

[0093] Test Example 3: Observation of Adverse Reactions in Rats 1. Laboratory animals Fifty-four male SPF-grade SD rats, weighing 200-220g, were kept at a room temperature of 23±2℃ and under alternating light and dark lighting for 12 hours, while being fed regular feed and having access to their own drinking water.

[0094] 2. Test substance and grouping In this experiment, 54 SPF-grade female SD rats were randomly divided into 6 groups, with 9 rats in each group.

[0095] Dosing Example Groups: 3 groups, using the drug compositions prepared by the methods of Examples 1, 3, and 5, with a dosage of 210 mg / kg / day; Comparative groups: 2 groups, using the drug compositions prepared by methods of Comparative Examples 1 and 2, with a dosage of 210 mg / kg / d; Blank control group: Normal drinking water.

[0096] For the preparation of experimental drugs, use drinking water to make suspensions or solutions, and administer 2 mL each time.

[0097] 3. Test methods Male SD rats were acclimatized for 7 days and then randomly divided into four groups using a random number table: a blank control group, treatment example 1 group, treatment example 3 group, treatment example 5 group, treatment comparison group 1, and treatment comparison group 2. The rats were administered the medication by gavage once daily for 14 consecutive days. Their mental state, food and water intake, and body weight were closely monitored.

[0098] 4. Test Results 4.1 Gastrointestinal reactions In the blank control group, there were no significant changes in food intake and water intake. In the drug administration group, there were no significant changes in food intake and water intake, and no obvious diarrhea was observed. In the drug administration control groups, reduced food and water intake and some diarrhea were observed. Specifically, in drug administration control group 1 and drug administration control group 2, 4 and 1 rats, respectively, showed significantly reduced activity levels, and 6 and 1 rats, respectively, showed diarrhea.

[0099] 4.2 Changes in rat body weight Fourteen days after administration, the body weight of the blank control group increased significantly. Compared with the blank control group, there was no significant difference in body weight among the groups in each administration example. The body weight of rats in administration example 1 group decreased significantly, and three rats in administration example 2 group showed a significant decrease in body weight, which may be related to the decrease in food intake caused by gastrointestinal reactions. The specific changes in body weight are shown in Table 5.

[0100] Table 5. Changes in rat body weight

[0101] Note: ## P <0.01, compared with the blank control group.

[0102] The experimental results show that, under specific ratios of sibifluin, uridine, and adenosine, for example, a ratio of 7.0-10.0:0.9-1.2:1.0, this composition has a good therapeutic effect on phenylketonuria, reduces gastrointestinal reactions such as diarrhea caused by other component combinations, and also has good safety and anti-inflammatory effects, thus exerting a synergistic and detoxifying effect.

[0103] Test Example 4: An exploratory experiment on the role of ovarian insufficiency Experimental methods Animal model construction method: 10-week-old female C57 mice were injected intraperitoneally with 1,4-butanediol dimethylsulfonate (30 mg / kg) and cyclophosphamide (120 mg / kg) once a day for 7 consecutive days.

[0104] Grouping: Fifteen mice with ovarian insufficiency were randomly divided into three groups of five mice each: the model control group, drug group 1, and drug group 2.

[0105] Administration: Simultaneously with the establishment of the animal model, mice in each drug group were administered the drug via oral gavage once daily for 14 consecutive days. Drug group 1 received the drug composition prepared according to the method in Example 1 via oral gavage at a dose of 100 mg / kg; Drug group 2 received the drug composition prepared according to the method in Comparative Example 1 via oral gavage at a dose of 100 mg / kg; the model control group received physiological saline via oral gavage. The volume of the gavage fluid was 0.1 mL / 10 g based on the mouse's body weight. The control group mice received an equal volume of physiological saline via oral gavage daily. The drugs were prepared in physiological saline.

[0106] Treatment: After 14 days of drug administration, the mice were sacrificed and ovarian tissue was collected. One ovary was fixed with 4% paraformaldehyde, embedded in paraffin, and then serially sectioned (each section was 5 μm, and one section was collected every 5 sections). The 5 sections containing the largest facet of each ovary were stained with HE, and the primordial follicles, primary follicles, secondary follicles, corpus luteum, and atretic follicles were counted and statistically analyzed.

[0107] The results showed that, compared with the model control group, the number of follicles at all stages of the ovary of mice in drug group 1 was significantly increased, the number of corpora lutea was significantly increased, and the number of atretic follicles was decreased; compared with the model control group, the number of follicles at all stages of the ovary of mice in drug group 2 was significantly increased, the number of corpora lutea was slightly increased, and the number of atretic follicles was decreased.
