Description

[Technical Field]

[0001] This application claims priority to Australian Provisional Application No. 2021 / 904274 (filed on 24 December 2021), which is incorporated herein by reference in its entirety.

[0002] The present disclosure relates generally to novel compounds, methods for their synthesis, and their use in treating psychiatric or central nervous system disorders. [Background technology]

[0003] Mental illness encompasses many neuropsychiatric disorders that place a significant burden on the lives of those affected. Diagnoses such as treatment-resistant depression, major depressive disorder, eating disorders, substance abuse disorders, post-traumatic stress disorder, obsessive-compulsive disorder, attention deficit disorder, and schizophrenia can cause devastating symptoms that disrupt the ability of many affected individuals to lead normal lives.

[0004] A variety of serotonergic medications, including antidepressants, serotonin reuptake inhibitors, monoamine oxidase inhibitors, and selective serotonin reuptake inhibitors, are commercially available to treat psychiatric disorders. Unfortunately, in many indications, these medications offer limited benefit compared to placebo. Additionally, these medications can result in a wide range of side effects, including loss of libido, insomnia, fatigue, and weight gain. Despite their limited efficacy, these medications continue to be used to treat neuropsychiatric conditions and a wide range of adjunctive medical indications. Since the launch of many of these medications, progress in new treatment options has been limited, and the pharmaceutical industry is facing increasing financial pressure to fully deemphasize neuroscience programs. There is a growing unmet need for more effective mental health treatments, and the global COVID-19 pandemic may increase the burden of disease worldwide.

[0005] The use of psychedelic drugs to treat various mental illnesses was widely studied in the 1950s and 1960s, and these substances showed promise as treatments for many disorders of the central nervous system (CNS). After decades of prohibition, scientific research into the application of psychedelics as treatments for mental illness is gaining momentum. The serotonergic psychedelic agent psilocybin has been designated a breakthrough therapy by the FDA for the treatment of major depressive disorder (2019) and treatment-resistant depression (2018). Psilocybin is a prodrug compound produced by the many species of mushrooms collectively known as psilocybin mushrooms or "magic mushrooms." Psilocybin is rapidly metabolized into the bioactive compound psilocin, which produces states of altered consciousness, including altered perceptions, visual hallucinations, and distorted senses of space, time, and self. Many patients report spiritual or "mystical" experiences that have profound and lasting effects on their mood and behavior. Psilocybin has shown promise in over 50 clinical trials for neuropsychiatric indications, including numerous anxiety disorders, obsessive-compulsive disorder, anorexia nervosa, alcoholism, and tobacco dependence. Psilocybin, as well as other psychedelic compounds such as N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT), have both immediate and persistent effects on mental state, the latter continuing well beyond the duration of action, likely as a result of their ability to induce increased neuroplasticity in the brain, promote neuronal proliferation, and increase spine density of synaptic neurons.

[0006] To date, psilocybin is classified as a controlled substance and / or drug of abuse in most countries under national drug laws. However, recently, clinical research has led to increased awareness of the potential of psychedelic drugs as breakthrough therapies for treating CNS disorders with enormous unmet medical need.

[0007] Despite their therapeutic potential, psilocybin and other psychedelics remain scheduled as drugs of abuse in most countries, and the commercial path to market for these drugs as medicines is uncertain. As adjuncts to psychotherapy, the long duration of action of psilocybin and LSD makes treatment sessions expensive and impractical for widespread implementation. Despite a long history of safe human use, several adverse events have been reported in clinical trials, which may be attributed to signaling bias at the 5-HT2A (primary target) or to off-target activity at, for example, the 5-HT2B receptor (cardiac liability antitarget), the 5-HT1A (anxiolytic target), or the 5-HT2C receptor (disease-associated target, e.g., obesity and some genetic epilepsies). Naturally occurring psychedelics provide important leads for a new generation of neurotherapeutics with novel mechanisms of action and / or superior clinical efficacy to currently available neuropsychiatric drugs.

[0008] In view of the foregoing, there is a continuing need to develop new compounds that may be useful in the treatment of psychiatric or central nervous system disorders.

[0009] The reference to any prior art herein is not an admission or suggestion that this prior art forms part of the common general knowledge in any jurisdiction, or that this prior art would be understood by, considered relevant, and / or could reasonably be expected to be incorporated into other pieces of prior art by a person skilled in the art.

Each ring can contain up to about four heteroatoms, typically selected from nitrogen, sulfur, and oxygen. Heteroaryl rings contain up to four heteroatoms, more typically up to three heteroatoms, and more usually up to two heteroatoms, e.g., a single heteroatom. In one embodiment, a heteroaryl ring contains at least one ring nitrogen atom. The nitrogen atoms in a heteroaryl ring can be basic, as in the case of imidazole or pyridine, or essentially non-basic, as in the case of indole or pyrrole nitrogens. Generally, the number of basic nitrogen atoms present in a heteroaryl group, including any amino group substituents on the ring, is less than five.

A 250 mM stock solution of probenecid in FLIPR calcium assay buffer (10 mL) was freshly prepared and combined with the fluorescent dye (Fluo-4 Direct) to give a final assay concentration of 2.5 mM. The reference compound was serially diluted 4-fold, and the screening compound was serially diluted 3-fold in 100% DMSO for 10 points using an Agilent Bravo, and 750 nL was added to a 384-well compound plate using an Echo along with 30 μL of assay buffer. The fluorescent dye was then added to the assay plate along with the assay buffer to a final volume of 40 μL. The cell plate was incubated at 37°C and 5% CO2 for 50 minutes and placed in a FLIPR Tetra along with the compound plate. 10 μL of the reference and compound were then transferred from the compound plate to the cell plate, and the fluorescent signal was read. [Table 1-1] [Table 1-2] [Table 1-3] [Table 1-4]

[0323] In vivo pharmacokinetic experiments Prospective in vivo pharmacokinetic studies are conducted using established procedures in accordance with the Australian Code of Practice for the Care and Use of Animals for Scientific Purposes, and study protocols are reviewed and approved by the Monash Institute of Pharmaceutical Sciences Animal Ethics Committee. A brief summary of the standard methods previously used is provided below: Systemic exposure of selected examples will be investigated in non-fasted male C57BL / 6 mice weighing between 18.9 and 25.5 g. Mice will have free access to food and water throughout the pre-dose and post-dose sampling periods.

[0324] On the day of administration, each compound formulation is prepared by dissolving the solid compound in the appropriate solvent using a vortex.

[0325] Compounds are administered to mice via IP injection (10 mL / kg dose volume via a 27G needle; n = 9 mice per compound), and blood samples are collected at various time points (e.g., 5 and 30 minutes, 1, 2, and 4 hours post-dose (n = 3 mice per time point for each compound)). Up to three blood samples are obtained from each mouse, and plasma samples are collected via submandibular bleeding (approximately 120 μL). Once collected, blood samples are processed by standard methods and analyzed by LCMS. In addition, immediately after blood collection, whole brain samples are collected by rapid removal from the carcass. Whole brains are blotted to remove excess blood and placed in pre-weighed polypropylene vials and weighed. Brains are snap-frozen in dry ice and then stored frozen (-80°C) until analysis.

[0326] Overview of bioanalytical methods: The concentrations of test compounds in plasma and tissue samples are determined using an LCMS / MS method validated for linearity, precision, accuracy, matrix factor, and recovery. Test compound standard solutions are diluted from concentrated stock solutions (32 mM in HO) using 50% ACN (v / v) in HO, and a calibration curve is prepared in a matrix matched to the test samples.

[0327] Plasma: Plasma calibration curves are prepared by spiking aliquots (25 μL) of blank mouse plasma with test compound standard solution (5 μL) and internal standard solution (5 μL of diazepam, 5 μg / mL in 50% acetonitrile in water). Test plasma samples (25 μL) are thawed, mixed, and then spiked with internal standard solution (5 μL). Plasma protein precipitation can be performed by adding acetonitrile (3x volume ratio) and thorough vortex mixing. Samples are centrifuged (RCF = 9391 × g) for 3 minutes, and the supernatant (90 μL) is collected for analysis.

[0328] Tissue: Pre-weighed tissue samples (brain) were prepared according to standard methods, for example, homogenized using a glass rod in a buffer containing EDTA / potassium fluoride solution (0.1 M / 4 mg / mL) as a stabilizing cocktail to minimize the possibility of ex vivo degradation (3 mL cocktail / g tissue). The tissue homogenate was briefly centrifuged for 10 seconds (RCF = 79 × g) to separate the foam layer, and then an aliquot (200 μL) of the tissue homogenate was transferred to a fresh Eppendorf tube for sample extraction. Calibration standards were prepared by spiking blank brain homogenate (200 μL) with the solution standard (10 μL) and the internal standard (10 μL). Investigational samples were prepared similarly, except that acetonitrile (10 μL) was added instead of the solution standard to maintain the same volume. Protein precipitation can be performed by adding 3 volumes of acetonitrile, followed by vortex mixing and centrifugation (RCF=9391×g) for 3 minutes, and the supernatant can be collected for analysis.

[0329] Analytical Replicates: Triplicate analytical replicate (AR) samples are prepared as well as standards of each sample type at three concentrations (50, 500, and 2,000 ng / mL), and repeat injections of these ARs are included throughout the analytical run to assess assay performance. Extraction of test compounds from standards and ARs is performed as described above.

[0330] All test samples are quantified within the calibration range of the assay, and the stability of each test compound is confirmed in the homogenate for the duration of sample processing (15 min; less than 15% loss).

[0331] Biotelemetry and Head Twitch Response (HTR) Experiments Psychedelic potential is assessed via the industry-standard head-twitch response in mice (C57BL / 6J males). The study is conducted via standard procedures, summarized below. Mice are purchased from Jackson Laboratory (Bar Harbor, ME, USA) at 5-6 weeks of age and allowed to acclimate to the animal research facility for at least 1-2 weeks. During acclimation, mice are grouped 3-5 per cage and housed on a 12-h light-dark cycle throughout the study, with lights on at 0700 h. Food and water will be available ad libitum, except during testing. Cohorts of 20-24 mice are used for each test drug. Mice are subjected to experimental testing once every 1-2 weeks over a 2-3 month period to complete dose-effect curves and antagonist experiments. A minimum of 7 days between treatments is utilized to avoid tolerance to the effects of repeated drug administration. All drug doses represent the weight of the salt dissolved in 0.9% saline vehicle. Mice are first tested in dose-response studies to assess the effects of each compound at subcutaneous doses of 0.03 to 30 mg / kg, followed by antagonist reversal studies utilizing pretreatment with M100907 and WAY100635. All experiments are performed during the light phase, between 0900 and 1700 local time, because rodent sensitivity to other tryptamine psychedelics is diurnal, with maximum HTR observed in the middle of the light phase. Experiments are also performed during the light phase to avoid potential effects of melatonin receptor activity on HTR, because melatonin and related agonists are known to reduce DOI-induced HTR in rats. For each experiment, mice are allowed to acclimate to the testing room in their home cages for at least 1 h before the experimental session. Behavioral testing sessions are conducted in a TruScan mouse locomotor arena equipped with a photobeam array (Coulbourn Instruments, Holliston, Mass., USA), modified with a cylindrical insert and transparent floor useful for detecting mouse HTR.

[0332] Subcutaneous temperature transponder implantation. At least 1 week before the start of the experiment, mice received subcutaneously implanted temperature transponders (14 x 2 mm, model IPTT-300, BioMedic Data Systems, Inc., Seaford, DE, USA) under brief isoflurane anesthesia. Mice were single-housed after implantation for the remainder of the study to protect the transponders from removal by cagemates. Temperature was determined noninvasively using a handheld receiver sensitive to the signal emitted from the implanted transponder.

[0333] Before each experiment, mouse weight and body temperature were recorded. The mice were then placed in the testing room for acclimation. For dose-response studies, after a brief 5-minute acclimation period, mouse body temperature was recorded for baseline measurements, the mice received a subcutaneous injection of the test substance or vehicle, and the animals were returned to the testing arena for 30 minutes. During the session, locomotor activity was monitored via photobeam tracking of movement in the horizontal plane, yielding distance traveled in centimeters. HTR was monitored by analyzing GoPro Hero Black 7 video recordings (120 frames / s and 960p resolution) using a commercially available software package from Clever Sys Inc. (Reston, VA, USA). Post-treatment body temperature values ​​were also recorded, and temperature data were expressed as the change from the pretreatment baseline.

[0334] In the antagonist reversal experiment, mice received a subcutaneous injection of either receptor antagonist or vehicle and were returned to the testing chamber for 30 minutes. During this period, locomotor activity was monitored to examine potential effects of antagonist treatment on general behavior or movement. Thirty minutes after antagonist administration, mice were given the test drug or vehicle and returned to the chamber for an additional 30 minutes of video recording, which was used for analysis.

[0335] All statistical analyses are performed using GraphPad Prism 9 (La Jolla, CA, USA). Dose-response data from mouse experiments are analyzed using nonlinear regression, and efficacy values ​​are determined from the ascending phase of the curve for HTR measurements. For mouse studies, one-way ANOVA with Dunnett's post-hoc test is used to compare all conditions with the vehicle control (0 or 0.0) in dose-response and antagonist experiments. The mean HTR counts, distance traveled, and temperature change for each condition are used for statistical comparison. For all analyses, alpha is set to 0.05.

[0336] Acute restraint stressor (ASR) tail suspension test (TST) in mice Compounds are evaluated in a validated model of depression conducted by Europhins Panlabs, a leading contract research organization. Evaluations are performed according to standard conditions, briefly outlined here: Male ICR mice (23 ± 3 g) are purchased from BioLASCO (Taipei, Taiwan) at 4–5 weeks of age and acclimated for 5–7 days to the animal research facility at Pharmacology Discovery Services (Taipei, Taiwan). Mice are housed in groups of 10 in large cages (47 × 25 × 15 cm) on a 12-hour light cycle (lights on: 07:00) and provided with food and water ad libitum, except during acute restraint stress and tail suspension testing. Temperature was maintained at 20–24 °C, and all rooms (colony and testing room) had similar lighting intensities. All aspects of this work, including housing, experimentation, and animal disposal, were conducted in a facility certified by the Association for Assessment and Accreditation of Laboratory Animal Care in accordance with the "Guide for the Care and Use of Laboratory Animals: Eighth Edition" (The National Academies Press, Washington, DC, 2011). All experiments were conducted during the light phase between 09:00 and 17:00 local time. Each mouse underwent a single behavioral experiment in which mice were randomly assigned to receive a single treatment with vehicle (50 mM phosphate-buffered saline, pH = 6.5), ketamine (10 mg / kg, diluted in 0.9% saline from a 50 mg / ml stock) as a positive control, or one dose of test drug (n = 10 per dose of test drug; n = 12 for vehicle, n = 12 for ketamine). All drug doses represent the free base dose of the salt form dissolved in vehicle. All solutions are delivered via intraperitoneal injection at 5 ml / kg.

[0337] Acute Restraint Stress (ARS) Procedure: Mice were moved from the colony room to the treatment room where ARS was performed. To prevent dehydration, mice were given 10 ml / kg of water by oral gavage. They were then individually restrained for 5 hours in a clear plastic cylinder (a 50 mL centrifuge tube with air holes drilled for ventilation) placed horizontally on a bench with a bench towel to absorb urine. This restraint prevented physical movement without causing pain. The restrainer was cleaned with veterinary disinfectant between mice.

[0338] Drug administration: Immediately after the 5-hour ARS procedure, mice are removed from the restrainer, placed in their home cages, and transferred to the room where the tail suspension test is performed. Mice are then intraperitoneally injected with vehicle, ketamine (10 mg / kg), or test compound (a range of doses), and returned to their home cages. Then, 10 minutes after treatment, animals undergo the tail suspension test.

[0339] Tail Suspension Test (TST) Procedure: Mice are individually suspended from the end of a 58 cm shelf on a table surface using adhesive tape placed approximately 1 cm from the tip of the tail for a total duration of 7 min. Using a stopwatch, an experimenter blinded to treatment group records the duration of immobility (defined as passively hanging and not moving) for 5 min over a period of 2–7 min. Data from 0–2 min are not recorded. Mice undergoing the TST are never within sight of other mice. After the TST, mice are euthanized by carbon dioxide inhalation.

[0340] Statistical analysis: Statistical analysis was performed using GraphPad Prism 9 (La Jolla, CA, USA) using a priori simple effects comparisons within a one-way ANOVA to compare test compounds with vehicle conditions for time spent immobile (seconds).
