Abstract
Description
Technical Field
[0001] This application relates to the field of biomedicine, and specifically relates to a composition and its application in the treatment of autism spectrum disorder. Background Art
[0002] Autism spectrum is usually simply referred to as autism, that is, autism spectrum disorder (English: autism spectrum disorders, ASD; or autism spectrum conditions, ASC) under professional diagnosis, which belongs to the neurodevelopmental disorder syndrome. Its main clinical manifestations are abnormal nature of social interaction and communication patterns, limited, stereotyped and repetitive interests and activities. Some patients are also accompanied by intellectual deficiency, delayed or retarded cognitive development, and loss of acquired developmental skills after a certain period of normal development.
[0003] Currently, there is no specific drug for ASD. The main treatment methods are to improve the patient's social interaction ability through education and training, master life skills and learning skills, and supplemented with drugs to reduce co-morbid symptoms. Antipsychotic drugs have been approved for the treatment of autism. The US FDA approved risperidone in 2006 and aripiprazole in 2009 for the treatment of young ASD patients. Such drugs mainly regulate dopamine in the brain to improve the irritable response and aggressive behavior related to ASD patients.

Detailed implementation manners
[0053] The following specific embodiments illustrate the implementation manners of the invention of the present application. Those skilled in the art can easily understand other advantages and effects of the invention of the present application from the content disclosed in this specification.
[0054] Term definitions
[0055] In the present application, the term "taurine" also known as 2-aminoethanesulfonic acid (IUPAC nomenclature) is a sulfonic acid with an amino group. The CAS number of taurine is 107-35-7 and its molecular formula is C2H7NO3S. The interchangeable use of "taurine" and "L-taurine" refers to the same organic compound.
[0056] In the present application, the term "beta-blocker" also known as Beta receptor blocking drug, β receptor blocker, β receptor antagonist or β blocker, beta-blocking agent, generally refers to a class of substances that can inhibit the activity of β-receptors. Beta-blockers can bind to β-receptors and thus inhibit their activity. For example, beta-blockers can block the binding of β-receptors to adrenaline and noradrenaline, thereby inhibiting their activity. Beta-blockers can have effects such as slowing heart rate, reducing blood pressure, decreasing cardiac contractility, controlling arrhythmias, reducing myocardial oxygen consumption, and controlling hyperthyroidism.
[0057] β receptors are mainly divided into three subtypes: β1 receptors, β2 receptors, and β3 receptors, which have different distributions and functions in different tissues and organs. β1 receptors are mainly distributed in the heart and adrenal tissues, regulating the contractility and heart rate of the heart, as well as the release of adrenaline. β2 receptors are widely distributed in various tissues, such as bronchial smooth muscle, vascular smooth muscle, hepatocytes, and muscle tissues, etc., and are involved in regulating physiological processes such as bronchial dilation, vasodilation, and glycogenolysis. β3 receptors are mainly present in adipocytes and the digestive system, regulating fat metabolism and energy consumption. β-blockers can be divided into 4 categories: ① non-selective β-blockers, which can block both β1 and β2 receptors simultaneously; ② β1 receptor-selective β-blockers, which mainly act on β1 receptors; ③ β2 receptor-selective β-blockers, which mainly act on β2 receptors; ④ mixed α and β-blockers, which can act on both β-receptors and α-receptors.
[0058] In the present application, the term "pharmaceutically acceptable salt" generally refers to a salt suitable for contact with human and animal tissues. Pharmaceutically acceptable salts include acid and base addition salts. The term "pharmaceutically acceptable acid addition salt" generally refers to such a pharmaceutically acceptable salt formed by using inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, carbonic acid, phosphoric acid, and organic acids selected from aliphatic, alicyclic, aromatic, aralkyl, heterocyclic, carboxylic acid, and sulfonic acid types, such as formic acid, acetic acid, propionic acid, glycolic acid, gluconic acid, lactic acid, pyruvic acid, oxalic acid, malic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, aspartic acid, ascorbic acid, glutamic acid, anthranilic acid, benzoic acid, cinnamic acid, mandelic acid, pamoic acid, phenylacetic acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, and salicylic acid. The term "pharmaceutically acceptable base addition salt" generally refers to those pharmaceutically acceptable salts formed with organic or inorganic bases. Examples of available inorganic bases include sodium salts, potassium salts, ammonium salts, calcium salts, magnesium salts, iron salts, zinc salts, copper salts, manganese salts, and aluminum salts. Salts derived from pharmaceutically acceptable organic non-toxic bases include salts of the following: primary amines, secondary amines, and tertiary amines, substituted amines, including naturally occurring substituted amines, cyclic amines, and basic ion exchange resins, such as isopropylamine, trimethylamine, diethylamine, triethylamine, tripropylamine, ethanolamine, 2-diethylaminoethanol, trimethylamine, dicyclohexylamine, lysine, arginine, histidine, caffeine, procaine, hydrabamine, choline, betaine, ethylenediamine, glucosamine, methylglucosamine, theobromine, purine, piperazine, piperidine, N-ethylpiperidine, and polyamine resins. These salts can be formed by processes known and described in the art.
[0059] In the present application, the term "pharmaceutical composition" generally refers to a preparation in a form that permits the biological activity of the active ingredient to be effective, and which does not contain additional ingredients that are unacceptably toxic to the subject to which the preparation is to be administered. These preparations can be sterile. The pharmaceutical composition can also contain one or more pharmaceutically acceptable carriers. The acceptable ingredients of the pharmaceutical composition are preferably non-toxic to the recipient at the dosages and concentrations used.
[0060] In the present application, the term "pharmaceutically acceptable carrier" generally refers to any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic agents, absorption delaying agents, etc. that are compatible with the administration of a drug. The use of such media and agents for active pharmaceutical substances is well known in the art. Any conventional media or agent can be considered for use in the pharmaceutical compositions of the present application, unless it is incompatible with the active compound.
[0061] In the present application, the term "treatment" generally includes: (1) preventing a subject from developing adverse symptoms and pathological conditions that the subject is predisposed to develop but has not yet been diagnosed with; (2) inhibiting adverse symptoms and pathological conditions, i.e., controlling their development; or (3) improving or alleviating adverse symptoms or pathological conditions, even if the above adverse symptoms or pathological conditions regress. For example, the treatment of autism spectrum disorder as described in the present application can include the alleviation of symptoms associated with autism spectrum disorder, regardless of whether the subject is diagnosed with autism spectrum disorder.
[0062] In the present application, the term "autism spectrum disorders (ASD)" is also referred to as "Autism spectrum" or "Autism", and generally refers to a neurodevelopmental disorder syndrome and its related symptoms. According to the fifth edition, revised (DSM-5-TR) of the Diagnostic and Statistical Manual of Mental Disorders and the eleventh edition (ICD-11) of the International Classification of Diseases, autism is generally understood as a spectrum disorder. For example, the autism spectrum disorder described in the present application may include a certain level of autism spectrum disorder (ASD), level 1 ASD, level 2 ASD, level 3 ASD, autism ("classical autism"), Asperger syndrome ("high-functioning autism"), pervasive developmental disorder (PDD "atypical autism"), pervasive developmental disorder not otherwise specified (PDD-NOS), childhood disintegrative disorder, developmental disorders related to autism spectrum disorder, speech and language delay (SLD), obsessive-compulsive disorder (OCD), social disorder, intellectual disability, learning disability, sensory processing, attention deficit disorder (ADD), attention deficit hyperactivity disorder (ADHD), speech disorder, language disorder, social deficit, social interaction deficit, repetitive stereotyped behavior (RBB), repetitive stereotyped interest, repetitive stereotyped activity, global developmental delay or one or more of other behaviors, intellectual or developmental delays.
[0063] Autism spectrum disorder and / or its related symptoms can be evaluated by a variety of methods known in the art. The Autism Behavior Checklist (ABC scale) is one of the most widely used autism assessment scales in China at present. The ABC scale (Autism Behavior Checklist) was developed by Krug in 1978. The table lists 57 behavioral characteristics of children with autism, including five aspects: Sensory, Relating, Body and object use, Language, and Social and self-help, and is used for children aged 2-14. Commonly used scales also include the Autism Diagnostic Observation Schedule (ADOS), the Autism Diagnostic Interview-Revised (ADI-R), the Childhood Autism Rating Scale (CARS), the Social Responsiveness Scale (SRS), the Vineland Adaptive Behavior Scales (Vineland-II), the Ohio Autism Clinical Global Impression Scale (OACIS), the Repetitive Behavior Scale-Revised (RBS-R), and the Yale-Brown Obsessive Compulsive Scale for Children with Autism Spectrum Disorder (CYBOSC-ASD).
[0064] In this application, the term "memory disorder" generally refers to a condition where an individual has problems in acquiring, storing, recalling, or using information. Such problems can be temporary or long-term and may be caused by various factors, including brain injury, neurological diseases, drugs or drug abuse, emotional or mental health problems, etc. The social impairments in individuals with autism spectrum disorder can manifest as one or more of the following: social memory disorder, including difficulty in remembering others' names, faces, emotional states, or social rules; non-verbal memory disorder, such as disorders in spatial memory, visual memory, or motor memory, forgetting specific figures, positions, sequences, or actions; excessive attention to details and difficulty in integrating information into a meaningful whole; perseverative interests and attention, being overly engaged in specific interests or activities, resulting in interference with attention and memory for other information or events; emotional memory disorder, for example, difficulty in recalling past emotional experiences or difficulty in understanding and expressing emotions. Memory disorders can be evaluated by methods known in the art, such as cognitive function tests, standardized memory assessment tools, etc. Commonly used standardized memory assessment tools can include the Wechsler Memory Scale, the Brief Assessment of Cognition in Schizophrenia (BACS), the Rey Complex Figure Delayed Recall Test, etc.

[0146] On the other hand, the present application provides the use of the composition described in the present application and / or the pharmaceutical composition described in the present application in the treatment of autism spectrum disorder.
[0147] The treatment method described in the present application may include combination therapy of taurine and a β-blocker. For example, combination therapy for autism spectrum disorder or related symptoms.
[0148] Compared with the individual effects of taurine and β-blockers, the treatment method described in the present application may have a better therapeutic effect on autism spectrum disorder. For example, the better therapeutic effect may be reflected in an increase in the types of symptoms related to autism spectrum disorder that are improved. For example, the better therapeutic effect may be reflected in an increase in the degree of improvement of a certain symptom related to autism spectrum disorder.
[0149] The combination therapy described in the present application may include simultaneously administering the taurine described in the present application and the β-blocker described in the present application in the same or different dosage forms, or separately administering the taurine described in the present application and the β-blocker described in the present application (e.g., sequentially). Thus, taurine and the β-blocker may be simultaneously administered in a single formulation. Alternatively, taurine and the β-blocker may be formulated for separate administration and administered simultaneously or sequentially (e.g., taurine is administered within about 30 minutes before the β-blocker is administered).
[0150] For example, the taurine described in the present application may be administered first, and then (e.g., immediately thereafter) the β-blocker described in the present application may be administered, or vice versa. In certain embodiments, the β-blocker described in the present application is administered before the taurine is administered. In certain embodiments, the β-blocker described in the present application is administered after the taurine is administered. In certain embodiments, the taurine described in the present application and the β-blocker described in the present application are administered simultaneously.
[0151] In certain embodiments, the dosages of the taurine and / or β-blocker described in the present application are calculated according to body weight, such as mg / kg body weight. For example, the dosages of the taurine and / or β-blocker described in the present application may be 5 mg / kg - 500 mg / kg.
[0152] In certain embodiments, based on the dose administered to a murine animal model, the total dose of taurine and the β-blocker can be 55 mg / kg - 1000 mg / kg. In certain embodiments, based on the dose administered to a murine animal model, the total dose of taurine and the β-blocker can be 205 mg / kg - 505 mg / kg. In certain embodiments, based on the dose administered to a murine animal model, the dose of taurine can be 50 mg / kg - 500 mg / kg, and the dose of the β-blocker can be 5 mg / kg - 200 mg / kg. In certain embodiments, based on the dose administered to a murine animal model, the dose of taurine can be 500 mg / kg, 450 mg / kg, 400 mg / kg, 350 mg / kg, 300 mg / kg, 250 mg / kg, 200 mg / kg, 150 mg / kg, 100 mg / kg, or 50 mg / kg; the dose of the β-blocker can be 5 mg / kg, 10 mg / kg, 15 mg / kg, 20 mg / kg, 30 mg / kg, 40 mg / kg, 50 mg / kg, 60 mg / kg, 70 mg / kg, 80 mg / kg, 90 mg / kg, 100 mg / kg, 150 mg / kg, or 200 mg / kg.
[0153] The administration doses for different subjects, such as between humans and non-human animals, can be converted according to methods known in the art. A conventional method for extrapolating the human dose based on the dose administered to a murine animal model can be used with a conversion factor for converting the mouse dose to the human dose: human dose / kg = mouse dose / kg × 12. See Freireich et al., Cancer Chemother Rep. 50, 219 - 244 (1966). The drug dose can also be given in mg per square meter of body surface area because this method has a better correlation with certain metabolic and excretion functions than body weight. In addition, body surface area can be used as a common characteristic for drug doses in adults, children, and different animal species. See Freireich et al., Cancer Chemother Rep. 50, 219 - 244 (1966).
[0154] Suitable methods for administering the compositions of the subject matter disclosed herein to an individual include, but are not limited to, systemic administration, parenteral administration, oral delivery, buccal delivery, subcutaneous administration, inhalation, intratracheal instillation, transdermal delivery, and local injection. The mode of administration used according to the methods of the present application depends on various factors, including but not limited to the drug and / or carrier used, the severity of the condition being treated, and the metabolic or elimination mechanism of the active agent after administration.

[0165] Operation procedures
[0166] 1. Mouse Modeling and Drug Administration
[0167] 1.1 Purchase and use of VPA
[0168] Sodium valproate, CAS No. 1069-66-5, was purchased from Aladdin. Weigh 0.594 g of VPA powder, add 9.94 ml of 0.9% NaCl and vortex until clear to obtain a 59.76 mg / ml VPA solution. The pregnant mice were subcutaneously injected at E12.5 with an injection volume of 600 mg / kg.

For the single-dose administration experiment, perform gavage at 9 am every day, once a day. The animals in the experimental group are given a quantitative drug, and the model group and the wild control group are given a quantitative solvent. Start the behavioral experiment after the specified administration time. Continuously administer the drug every day during the behavioral experiment until the end of the experiment.
[0175] 2. Behavioral tests
[0176] 2.1 Social memory test for mice
[0177] Divide the open field with a length of 1 m and a width of 40 cm evenly into 3 areas. Place a restraint cage (such as Figure 1 , define the left side as Cage A and the right side as Cage B) at the center of the first and third areas, within a range of 5 cm from the restraint cage (Area A-1; Area B-1).
[0178] The test environment has a room temperature maintained at 25°C, a humidity maintained at 30 - 40%, a quiet environment, no strong light irradiation, and no unauthorized personnel.
[0179] Adaptation period: On the first day, no mice are placed in Cages A and B. Place the experimental mice with their heads facing the inner wall of the open field and put them into the open field from the middle position to adapt for 30 minutes to familiarize themselves with the open field environment. After each group finishes, clean the cage and then replace it with the next group of animals for adaptation.
[0180] Social preference test: The test was conducted on the second day. A strange animal was placed in the restraint cage A, and B was an empty restraint cage (either B or A was selected to place the strange mouse based on the adaptation period data, and the strange mouse was placed in the area where the experimental animal had a weak preference). The experimental mice were placed in the middle facing the inner wall of the open field and tested for 10 minutes. The Anymaze software and camera were used to automatically record the movement trajectories and time of the mice, and the time the animals stayed within a range of 5 cm from the restraint cage was statistically analyzed. The behavior of staying within 5 cm near the restraint cage B where the strange mouse was placed was defined as prosocial behavior. After each group was tested, the cage was cleaned and the next group of animals was tested.
[0181] Social memory test: Four hours after the social preference test was completed, the social memory test was conducted. A familiar animal was placed in the restraint cage A, and a strange animal was placed in the restraint cage B. The experimental mice were placed in the middle facing the inner wall of the open field in sequence and tested for 10 minutes. The time the animals stayed within a range of 5 cm from the restraint cage was observed and recorded. After each group was tested, the cage was cleaned and the next group of animals was tested.
[0182] 2.2 Mouse pain transfer experiment
[0183] As Figure 2 shown, for the pain threshold test, Von Frey filaments of different thicknesses were used to stimulate the plantar surface of the mice, and the classical "up and down" method was used to record the experimental results, and the 50% paw withdrawal threshold of the mice was calculated according to the formula. The pain threshold test was carried out successively on a pain test stand 40 cm high, a 10*10*5 cm restraint cage, and using different fiber hairs (specifications: 0.008 g, 0.02 g, 0.04 g, 0.07 g, 0.16 g, 0.4 g, 0.6 g, 1 g).
[0184] The pain test stand was placed on the operating table, and the test mouse was fixed on the pain test stand with the restraint cage. (The bottom was illuminated with a table lamp to shine on the sole of the foot). After adapting for 2 - 3 h and waiting for the mouse to be quiet, the test was carried out. First, the fiber hair (0.07 g) suitable for the pain threshold critical weight of the mouse was selected as the first hair and tested successively. The fiber hair was continuously pricked on the plantar surface of the mouse, and the angle between the bent fiber hair and the plantar surface was 45°. If the test mouse showed a pain response within 5 s, it was marked with an "X" on the record form, otherwise with an "O". Each mouse was tested 6 times, and the interval between each test was 1 min. According to the reaction pattern of the mouse, the parameters were determined by referring to the reference table, and calculated using the formula to obtain the 50% PWT value (paw withdrawal threshold), and then statistical analysis was carried out.
[0185] After the mouse's pain threshold baseline was tested, it was co-housed with a CFA pain mouse for 24 h, and the mouse's pain threshold was tested again for comparison.
[0186] 2.3 Mouse water maze memory test
[0187] As Figure 3As shown in the figure, the water pool for the mouse spatial memory test is a circular barrel with a water maze diameter of 1.2 meters, which is divided into four quadrants A, B, C, and D. Markers of different shapes are set at the 3 o'clock, 6 o'clock, 9 o'clock, and 12 o'clock positions on the barrel wall, and a platform is set at the midpoint of the line connecting the 6 o'clock and 9 o'clock positions. The platform is 2 centimeters below the water surface. Water is injected into the barrel and whitened with milk so that the platform is invisible.
[0188] The experimental animals are trained four times a day at intervals of 1 hour, with each time lasting 1 minute. The mice are placed into the water at the 4 o'clock, 3 o'clock, 2 o'clock, and 1 o'clock positions, allowing the mice to swim in the pool to find the position of the platform. If the animal does not find the platform position within 1 minute, it is manually guided to the platform to enable it to remember the platform position. The training lasts for 4 - 6 days. A camera is used to automatically record the swimming trajectories of the mice, and the ANY-maze software is used to analyze the swimming trajectories and swimming times of the mice. On the last day, the platform is removed, and the mice swim freely for 1 minute, and their movement trajectories are recorded.
[0189] During the training stage of the mice, calculate the time required for the mice to find the platform and plot the learning curve of the mice. The shorter the time required for the mice to find the platform (Escape latency), the stronger the spatial learning and memory ability of the mice.
[0190] During the free swimming stage of the mice after the platform is removed, analyze the swimming trajectories of the mice, calculate the number of times they cross the platform position (Number of crossing) and the time they swim in the B quadrant (Time in right quadrant). The more times the mice cross the platform position and the longer the time they swim in the B quadrant, the stronger the spatial learning and memory ability of the mice.
[0191] 3. Data analysis
[0192] GraphPad 8 and SPSS 25.0 are used for data processing and graphing, and repeated measures analysis of variance and one-way analysis of variance are used to compare statistical differences. All data are expressed as mean ± standard error. *, P < 0.05, **, P < 0.01, ***, P < 0.001, ****, P < 0.0001.
[0193] Example 1: Drug rescue of social deficits in VPA-induced autistic model mice
[0194] This example shows that the combined administration of taurine and β-blocker has a better effect on rescuing the social deficits in VPA-induced autistic model mice than their separate administrations.
[0195] C57BL6 / J mice are used for VPA-induced modeling. The offspring mice start to be medicated once a day for 11 consecutive days at 40 days of age (the dose is adjusted according to the commonly used clinical dose), and then a social experiment is conducted to test the effect of the drug on rescuing the memory deficits in autistic mice.
[0196] 1.1 Single drug: Test the rescue effects of 50 mg / kg propafenone, 30 mg / kg propranolol, 200 mg / kg taurine, 200 mg / kg atenolol, 3 mg / kg aripiprazole, and 125 mg / kg carvedilol.
[0197] 1.1.1 In the social preference test, in the VPA model group (P = 0.9905), there was no significant difference in the time spent in the two restraint cages, showing social deficits; in the wild control group (P < 0.0001) and the propafenone group (P = 0.0011), the time spent by mice in the restraint cage with a strange mouse was significantly higher than that in the empty restraint cage, showing obvious social preferences. In the social memory test, in the wild control group (P < 0.0001), the time spent in the restraint cage with a strange mouse was significantly higher than that in the restraint cage with a familiar mouse, showing significant social memory; in the VPA model group (P > 0.9999) and the propafenone group (P = 0.9995), there was no significant difference in the time spent in the two restraint cages, showing social memory deficits. The results are shown in Table 1 and Figure 6 as shown, feeding 50 mg / kg propafenone for 11 days can rescue the social preference deficit of autistic mice, but cannot rescue the social memory deficit.

[0200]
[0201] 1.1.2 In the social preference test, in the wild control group (P < 0.0001) and the taurine group (P < 0.0001), the time spent by mice in the restraint cage with a strange mouse was significantly higher than that in the empty restraint cage, showing obvious social preferences; in the VPA model group (P = 0.9897), there was no significant difference in the time spent in the two restraint cages, showing social deficits. In the social memory test, in the wild control group (P < 0.0001), the time spent in the restraint cage with a strange mouse was significantly higher than that in the restraint cage with a familiar mouse, showing significant social memory; in the VPA model group (P = 0.3164) and the taurine group (P > 0.9999), there was no significant difference in the time spent in the two restraint cages, showing social memory deficits. The results are shown in Table 2 and Figure 7 as shown, feeding 200 mg / kg taurine for 11 days can rescue the social preference deficit of autistic mice, but cannot rescue the social memory deficit.
