Description

[Technical Field]

[0001] (Cross-reference of related applications)

[0002] This patent application claims the benefit as of the filing date of U.S. Provisional Patent Application No. 63 / 504,034, filed on 24 May 2023 (the entire disclosure thereof is invoked by reference).

[0003] (Field of Invention)

[0004] This invention relates to formulations of tryptamine derivatives and the use of such formulations. [Background technology]

[0005] (Background of the invention)

[0006] Hallucinogenic compounds are a group of compounds that affect one or more biological activities (e.g., perception, mood, and cognitive processes). While there is great diversity in the structure and chemical activity of hallucinogenic compounds, they are known as a class that induces broad-spectrum neurological activity with rapid onset and sustained duration of action. Examples of well-known hallucinogenic compounds include psilocybin, N,N-dimethyltryptamine (DMT), 5-MeO-DMT, 4-AcO-DMT, lysergic acid diethylamide (LSD), and ibogaine, which mimic serotonin (5-HT) and target central nervous system (CNS) receptors.

[0007] Many hallucinogenic compounds are found in serotonin receptor 2A (5-HT). 2A It has a hallucinogenic effect due to agonism. However, agonism alone (including partial agonism) does not induce hallucinations, and 5-HT 2A The unique relationship between and metabotropic glutamate receptor 2 (mGlu2) deserves further investigation, especially since it is associated with addictive and compulsive behaviors. For example, signaling (e.g., G qIt has been shown that (or β-arrestin aggregation) is important for the downstream contribution to hallucinogenic effects. Furthermore, as those skilled in the art know, hallucinogenic compounds (e.g., those identified in the preceding paragraph) target various 5-HT receptors (of which 14 subtypes exist) along with other CNS receptors (adrenergic receptors, dopamine receptors, histamine receptors, muscarinic receptors, opioid receptors, sigma receptors, etc.). Thus, these compounds, among others, belong to the group known as psychedelics, but their mechanisms for eliciting activity in the body are diverse and complex. Furthermore, while the hallucinogenic compounds mentioned above have been well-known for many years, there has recently been a movement to develop novel compounds in this class. For example, many new compounds are described in WO 2021 / 226416 A1 (Novel Compositions of Matter and Pharmaceutical Compositions), published on November 11, 2021. The search for novel compounds, as well as desirable formulations of known compounds, is driven by the objective of better treating, preventing, and managing a wide variety of human conditions and disorders.

[0106] In some embodiments, tackifiers can be used to increase adhesion in transdermal formulations for long-term wearability. Common tackifiers include, but are not limited to, gums, resins (natural or modified resins), carbomers, or other natural or synthetic polymers.

[0107] In some embodiments, preservatives may be used in topical or transdermal formulations to improve formulation stability and delay microbial growth. Common preservatives include, but are not limited to, parabens, sorbates, benzoates, silica, chlorides, phenols, chlorhexidine, citric acid, triclosan, vitamin E (or tocopherol), chelating agents, metals, salts, and alcohols. Additionally or alternatively, the formulation may be emulsified with a hydrophilic component (e.g., water or Aloe barbadensis juice).

[0108] In some embodiments, the transdermal dosage form is a transdermal delivery device. Any device conventional in the art for transdermal delivery of therapeutic agents to a target may be used as a transdermal delivery device for transdermal delivery of the composition of the present invention. For example, the transdermal delivery device may be a reservoir-type transdermal delivery device, a polymer-matrix-type transdermal delivery device, a drug-containing adhesive-type transdermal delivery device, or a multilaminate-type transdermal delivery device. The transdermal delivery device may be designed so that the pharmacopoeia active ingredient of the present invention is delivered in a therapeutically effective amount when in contact with the target skin.

[0109] In some embodiments, the transdermal delivery device is a drug-containing adhesive device containing a medicinal active ingredient directly dispersed in a pressure-sensitive adhesive matrix. The adhesive matrix may be supported on its top by an impermeable backing film and on its skin-facing side by an impermeable release liner. To administer the medicinal active ingredient, the release liner is removed, exposing the adhesive matrix and bringing the device into contact with the skin. The adhesive matrix functions to adhere the device to the skin, typically controlling the delivery rate of the medicinal active ingredient. Similar to polymer-matrix designs, the design of this drug-containing adhesive allows the medicinal active ingredient to diffuse out of the adhesive matrix, come into contact with the target skin, and penetrate the skin. The delivery rate of the medicinal active ingredient is typically determined by the rate of diffusion of the medicinal active ingredient(s) from the adhesive matrix. Multiple drug-containing adhesive layers may be laminated together between rate-controlling films for longer-duration delivery. The delivery rate is such that an effective amount of the medicinal active ingredient is delivered to the target (e.g., a patient) that requires it.

[0110] In some embodiments, a reservoir-type transdermal delivery device includes a reservoir (typically liquid or semi-solid) located between an impermeable backing film and a rate-controlling membrane covered with a pressure-sensitive adhesive skin-contact layer. The reservoir (which may be a solution or suspension) contains the composition of the present invention. The transdermal delivery device may be supported by an impermeable backing film, and the surface of its adhesive is protected by a release liner. To administer the active pharmaceutical ingredient of the present invention, the release liner is removed to expose the pressure-sensitive adhesive, which is then brought into contact with the skin. The active pharmaceutical ingredient of the present invention is permeable to the rate-controlling membrane, penetrates through the membrane, the adhesive comes into contact with the skin, and then penetrates into the skin. The delivery rate of the active pharmaceutical invention is typically determined by the rate at which the active pharmaceutical ingredient penetrates the rate-controlling membrane.

[0111] In some embodiments, the transdermal delivery device is of a polymer-matrix design. In this polymer-matrix design, the API can be dispersed in a polymer matrix that controls the delivery rate. Preferably, the polymer-matrix reservoir is supported on an impermeable backing layer. An adhesive layer is attached to the surface of the polymer matrix. To administer the active pharmaceutical ingredient, the release liner is removed, exposing the polymer matrix and the ring of pressure-sensitive adhesive, and the device is brought into contact with the skin. The adhesive holds the device against the skin so that the polymer matrix is ​​in direct contact with the skin. Once the polymer matrix is ​​in contact with the skin, the active pharmaceutical ingredient(s) diffuse out of the polymer matrix, come into contact with the patient's skin, and penetrate the skin. The delivery rate of the active pharmaceutical ingredient is typically determined by the diffusion rate of the active pharmaceutical ingredient out of the polymer matrix.

[0112] Adhesives may contain crosslinkable monomer units or crosslinkable sites that can be incorporated into adhesive polymers. For example, a crosslinkable monomer may be incorporated into a polyacrylate polymer. The crosslinkable monomer may, for example, provide sites for crosslinking the polymer matrix after its API has been dispersed in the polymer. Known adhesives include crosslinkable monomers for polyacrylate polymers, and known adhesives include, for example: polymethacrylates of polyols (e.g., butylene diacrylate, butylene dimethacrylate, and trimethylolpropane trimethacrylate), polyisobutylene-type adhesives, and silicones. Other monomers that provide crosslinking sites include: allyl acrylate, allyl methacrylate, diallyl maleate, silyl ethers, and silanes. The monomers are then polymerized using methods known to those skilled in the art to form a polyacrylate (acrylic) adhesive matrix, a polysiloxane (silicone) adhesive matrix, or a polyisobutylene (or other rubber) adhesive matrix containing a crosslinking agent, a functional group, or vinyl acetate for suspending, stabilizing, and releasing the above-mentioned pharmaceutical active ingredient.

[0113] In some embodiments of the present invention, the transdermal delivery device may optionally contain one or more penetration enhancers, which increase the rate at which the medicinal active ingredient penetrates the target skin. Preferably, the penetration enhancer penetrates a rate control membrane or diffuses outward from a polymer matrix or adhesive matrix, and as a result, the penetration enhancer can come into contact with the target skin and improve the penetration of the medicinal active ingredient as defined herein through the target skin.

[0114] Suitable penetration enhancers for use in the transdermal delivery devices and compositions of the present invention include: for example, C 2~4Alcohols (e.g., ethanol and isopropanol), polyethylene glycol monolaurate, polyethylene glycol-3-lauramide, dimethyllauramide, polysorbate, sorbitan, fatty acids, esters of fatty acids having about 10 to about 20 carbon atoms, monoglycerides of fatty acids or mixtures of monoglycerides of fatty acids having at least 51% total monoester content (the monoester having 10 to 20 carbon atoms), and mixtures of monoglycerides of fatty acids, diglycerides of fatty acids, and triglycerides of fatty acids. Suitable fatty acids include, for example, lauric acid, myristic acid, stearic acid, oleic acid, linoleic acid, and palmitic acid. Examples of monoglyceride penetration enhancers include, for example, glycerol monooleate, glycerol monolaurate, and glycerol monolinoleate.

[0115] Additionally or alternatively, terpenes and terpenoids derived from natural isoprene biosynthesis may be used. These may be utilized to disrupt the skin film and increase API penetration. Examples of terpenes include, but are not limited to, menthol, menthone, camphor, nerolidol, limonene, myrcene, anethole, eugenol, 1,8-cineole, terpinolene, pinene, and humulene. In certain embodiments, the transdermal patches described herein are used in co-administration with a penetration enhancer. In certain embodiments, the penetration enhancer may include, but are not limited to, oils such as: castor oil, coconut oil, medium-chain triglycerides (MCT), jojoba oil, sunflower oil, argan oil, almond oil, olive oil, mineral oil, petrolatum, cocoa butter, and shea butter. Other penetration enhancers for use in transdermal patches include, for example, C 2~4Alcohols (e.g., ethanol and isopropanol), polyethylene glycol monolaurate, polyethylene glycol-3-lauramide, dimethyllauramide, polysorbate (Tween®), sorbitan (Span®), fatty acids, esters of fatty acids having about 10 to about 20 carbon atoms, monoglycerides of fatty acids or mixtures of monoglycerides of fatty acids having at least 51% total monoester content (the monoesters having 10 to 20 carbon atoms), and mixtures of monoglycerides of fatty acids, diglycerides of fatty acids, and triglycerides of fatty acids. Suitable fatty acids include, for example, lauric acid, myristic acid, stearic acid, oleic acid, linoleic acid, and palmitic acid. Examples of monoglyceride penetration enhancers include glycerol monooleate, glycerol monolaurate, and glycerol monolinoleate.

[0116] In some embodiments, the active pharmaceutical ingredient may be delivered by a daily topical application or transdermal patch. In some embodiments, the API may be delivered in less than 6 hours. In some embodiments, the API may be delivered between 6 and 12 hours. In some embodiments, the API may be delivered over a period of 12 to 24 hours. In some embodiments, the API may be delivered over a period of 24 to 48 hours. In some embodiments, the transdermal patch may be applied every 2 days; every 3 days; every 4 days; every 5 days; every 6 days; or every 7 days.

[0149] (Examples)

[0150] (Example 1 - Assay)

[0151] In vitro radioligand binding assays for various serotonergic receptors and sigma receptors are shown in Tables 1A and 1B.

[0152] [Table 1A-1] [Table 1A-2] [Table 1A-3]

[0153] [Table 1B-1] [Table 1B-2] [Table 1B-3]

[0154] In vitro receptor pharmacology reveals a wide range of serotonergic receptor and sigma receptor activity associated with various mental health disorders and neurodegenerative disorders.

[0155] (Example 2 - In vitro functional activity)

[0156] Table 2 below shows the functional activity of specific compounds. This functional activity is examined in comparison to agonism and antagonistism. In vitro pharmacology of specific serotonergic receptors shows agonism at 5-HT2A, 5-HT2C, and 5-HT6, but inverse agonism at 5-HT7A. Each of these receptors influences mental health, learning, and memory, and more specifically, 5-HT6 is involved in predictive effects as well as neuronal connectivity, neuronal growth, and neuronal migration.

[0157] [Table 2-1] [Table 2-2]

[0158] (Example 3 - Formulation used in in vivo animal experiments)

[0159] Formulations for the compounds identified in Example 2 were prepared. These formulations were used in mice for intravenous injection and in rats as oral formulations via po for PK / BBB, within limits that showed minimal side effects or minimal excipient incompatibility. The final concentration of each compound was approximately 5 mg / mL. For each compound, a typical formulation within the weight percentage range shown in Table 3 was used.

[0160] [Table 3]

[0161] (Example 4 - Mouse head-shaking response in vivo)

[0162] The head-shaking response is a preclinical assay that tests the hallucinogenic effect in mice by counting the number of times they shake their heads compared to a negative control (vehicle) or a positive control (4-AcO-DMT (a psilocybin-like psilocybin prodrug)), which is a hallucinogenic substance. The head-shaking response data for each compound (provided in Table 4 below) did not show statistically significant head shaking compared to the formulation vehicle. This indicates that each tryptamine derivative is unlikely to induce hallucinations induced by the 5-HT2A receptor in humans.

[0163] [Table 4-1] [Table 4-2]

[0164] (Example 5 - In vivo forced swimming test in mice)

[0165] The two-day Porsolt forced swim test is a preclinical assay to test the antidepressant effects in mice. Behavior on day 1 is generally presumed to be related to resilience, and longer swim times show similar antidepressant effects to the positive control (4-AcO-DMT). Behavior on day 2 is more likely to assess learning and memory, and shorter swim times indicate learning to be saved. The minimum effective dose for each active compound is presented in Table 5, which shows that each of the compounds shown has longer swim times on day 1 compared to the vehicle and shorter swim times on day 2 compared to the vehicle, indicating potential antidepressant effects as well as benefits for learning and memory.

[0166] [Table 5-1] [Table 5-2]

[0167] (Example 6 - In vivo mouse elevated cross maze)

[0168] The elevated cusp maze is a preclinical assay to test the anxiolytic effects in mice. Longer time spent in the open-arm sections or entry into the open-arm sections indicates similar anxiolytic effects to the positive control (4-AcO-DMT). As shown in Table 6, the results of this elevated cusp maze indicate that each compound has a potential anxiolytic effect that surpasses the anxiolytic effect shown by the placebo vehicle alone within the indicated dose range. Each compound showed greater entry into the arm sections and longer time spent in the open-arm sections compared to the vehicle.

[0169] [Table 6-1] [Table 6-2]

[0170] (Example 7 - In vivo fear extinction and conditioning in mice)

[0171] The fear extinction and conditioning model is a preclinical assay that involves performing a stimulus and testing the reaction time and recognition of that stimulus. This bridging model can relate anxiety, PTSD, memory, and predictive effects to a positive control (4-AcO-DMT). As shown in Table 7, each compound was shown to have a reduction in fear responses in the behavior of mice in this fear extinction and conditioning within the indicated dose range, suggesting potential in anxiety disorders, PTSD, learning disabilities, and memory impairments.

[0172] [Table 7]

[0173] (Example 8 - Reduction in alcohol consumption in mice in vivo)

[0174] To test the ability to suppress alcohol consumption, mice were given free access to 8%–20% alcohol for two weeks. Alcohol consumption was monitored for two weeks after daily administration of the test compound, relative to a positive control (4-AcO-DMT). Further studies extended this experiment to 60 days for three different doses, administering the test compound every three days to the mice. Alcohol consumption decreased similarly to near zero at 25 mg / kg and 35 mg / kg over the 60-day period, without any signs of tolerance development or negative effects. As shown in Table 8, the compound halted alcohol consumption in addicted mice within the indicated dose range, suggesting potential applications in human addiction (e.g., alcohol use disorder).

[0175] [Table 8]

[0176] (Example 9 - Comparison of oral and intravenous pharmacokinetics)

[0177] Using the formulation from Example 3, which contains 2-(2-bromo-1H-indole-3-yl)-N,N-dimethylethane-1-amine hydrobromide (also known as 2-Br-4-AcO-DMT*HBr), pharmacokinetic (PK) and metabolite profiles were established.

[0178] The pharmacokinetics (PK) of rats (Figure 6) were evaluated at an oral dose of 10 mg / kg and intravenously at 1 mg / kg. 2-Br-4-AcO-DMT*HBr was rapidly metabolized to its active metabolite, 2-bromo-3-(2-(dimethylamino)ethyl)-1H-indole-4-ol) (also called 2-Br-4-OH-DMT), by deacetylation within minutes of oral or intravenous (IV) administration. Its PK and brain concentration were evaluated by comparing plasma and brain concentrations in a cohort of three mice for each dose group. Table 16 below shows a summary of the PK parameters for the 10 mg / kg oral dose. 66% bioavailability was achieved by the conversion of 2-Br-4-AcO-DMT*HBr to 2-Br-4-OH-DMT via oral administration.

[0179] [Table 16]

[0180] Table 17 shows an overview of the PK parameters for intravenous (IV) administration at a dose of 1 mg / kg.

[0181] [Table 17]

[0182] Table 18 lists the comparisons between brain and plasma concentrations of 2-Br-4-AcO-DMT*HBr, derived from oral and intravenous (IV) administration, based on the detection of active 2-Br-4-OH-DMT.

[0183]

[0184] [Table 18]

[0185] (Example 10 - Nasal preparation)

[0186] The following formulations were prepared for intranasal delivery: 0.9% physiological saline and 0.1% DMT fumarate.

[0187] The pharmacokinetic (PK) and pharmacodynamic (PD) parameters of rats were collected. Comparisons of the rat PK (Figures 1A, 1B, 1C, and 1D) and PD (Figures 2A and 2B) included a comparison of intranasal and subcutaneous (sc) formulations of DMT fumarate at three different doses. The detected concentrations of both DMT and its metabolite, DMT-N-oxide (DMT-NO), were determined using a modified method similar to that of Eckernas et al. (Journal of Pharmaceutical and Biomedical Analysis 2022). Each dose group contained six rats, which were restrained before administration to allow for complete intranasal administration. The intranasal (in) dose of 3 mg / kg of DMT in rats was similar to the intravenous (iv) dose in humans. max (60 ng / mL) is produced (Figure 1A- to Figure 1D). A similar maximum effect (t) is observed in human intravenous (iv) doses. max The onset time (10 minutes) and duration (<60 minutes) were observed for intranasal (in) doses. Intranasal (in) administration of DMT also resulted in dose-dependent hypothermia, as observed in similar studies on psychotropic agents (Figures 2A-2B). See Glatfelter, GC et al., ACS Pharmacology and Translational Science 2022, 5, 1181-1196, DOI:10.1021 / acsptsci.2c00177. The data show that these formulations provide desirable results when administered intranasally.

[0188] Intranasal (in) delivery of N,N-dimethyltryptamine (DMT) eliminates the need for currently available invasive delivery routes in FDA clinical trials and avoids issues associated with DMT instability that could render some oral formulations (e.g., capsules or tablets) unfeasible as a delivery option. Furthermore, using intranasal delivery can overcome the bioavailability challenges reported with DMT formulations while still providing rapid onset of action, duration of action, and required plasma levels for effective administration.

[0189] (Example 11. Evaluation of CNS biomarkers of 2-Br-4-AcO-DMT (HBr salt))

[0190] To evaluate the effects on neuroplasticity and inflammatory biomarkers, in vitro assays were performed using the mouse immortalized hippocampal neuron cell line HT22, cloned from HT4 cells. Ketamine and psilacetin were used as control compounds, and the cells were exposed to 2-Br-4-AcO-DMT HBr salt for 24 hours. Brain-derived neurotrophic factor (BDNF; Figures 3B1 and 3B2) was quantified for neuroplasticity, and the cytokines interleukin-6 (IL-6; Figures 3A1 and 3A2) and TNFα (Figures 3C1 and 3C2) were quantified for inflammation, with or without pro-inflammatory treatment with lipopolysaccharide (LPS). LPS-induced inflammation is a model for neuroinflammation similar to that observed in patients with neurodegenerative disorders. Our data show that 2-Br-4-AcO-DMT reduces IL-6 and TNFα in stressed LPS cells (Figures 3A1, 3A2, 3C1, and 3C2) and increases BDNF, a neuroplasticity marker, in control cells (Figures 3B1 and 3B2). IL-6 levels are elevated in patients with frontotemporal dementia and other neurodegenerative disorders, particularly in patients in a disinhibited state.

[0191] (Example 12. Brain tissue protein expression in mice after treatment with 2-Br-4-AcO-DMT (HBr salt))

[0192] Metabotropic glutamate receptor 2 (mGlu2) expression in the prefrontal cortex was quantified after in vivo mouse studies. Modulation of metabotropic glutamate receptor 2 (mGlu2) levels in alcohol-seeking rats may reduce relapse behavior. Tissue was collected from multiple brain regions of male C57BL / 6J mice after 18 days of daily treatment with vehicle, silacetin, or 25 mg / kg of 2-Br-4-AcO-DMT (shown as 25 mg / kg in Figures 4A-4C) under either stress-free conditions or 2 hours of tube restraint daily. Mice treated with 2-Br-4-AcO-DMT showed reduced mGluR2 expression in both stress-free and stress-stressed mice (Figures 4A and 4B, two representative samples from each condition), outperforming the effect of silacetin (n=5-6; data calculated relative to actin and then normalized to vehicle) (Figure 4C). The data in Figure 4C are expressed as mean ± standard error of the mean (SEM).

[0193] (Example 13. Crystal structure of 2-Br-4-AcO-DMT bromide salt)

[0194] To produce the HBr salt form of 2-Br-4-AcO-DMT, 4-AcO-DMT was placed in a heated and dried round-bottom flask under argon. Anhydrous dichloromethane (DCM) was added to the flask. In a separate round-bottom flask, trimethylphenylammonium tribromide (PTT) was dissolved in anhydrous DCM under argon. The PTT solution was added dropwise to the reaction mixture. The reaction mixture was stirred for 20 minutes and then concentrated under reduced pressure. The crude product was loaded onto silica and purified by column chromatography using 0%-6% isopropyl alcohol in DCM. The pure product was subjected to isopropyl ether under reduced pressure to produce an azeotropic mixture and remove excess iPrOH. The product was finally subjected to freeze-dryer conditions to remove trace amounts of water.

[0195] The product was isolated as a grayish solid, a bromide salt. Figure 5 shows its crystal structure, which is monoclinic, P21 / c, and centrosymmetric (non-chiral). Within this structure, molecules form chains through NH…Br hydrogen bonds. The structure is further assembled through combinations of weak interactions (including CH…O, CH…π, CH…Br, and van der Waals). The structure contains four small voids (each approximately 10 A³) within the unit cell, and there is no electron density.
