PSILOCYBIN ANALOGS FOR TREATING PSYCHOLOGICAL DISORDERS

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority from Provisional Application number 63/215,411 , filed June 25, 2021 , the entire contents of which is hereby incorporated by reference.

FIELD OF THE INVENTION

[0002] The present disclosure provides compositions comprising a psilocybin analog and methods of using the compositions for treating a neurological disorder.

BACKGROUND OF THE INVENTION

[0003] It has been reported that about one in five American adults, an alarming 20% of the adult U.S. population, suffers from some form of mental illness or psychological disorder. It has also been reported that nearly half of the U.S. population, i.e., 46%, will have a diagnosable mental health condition at some point in their life, and that nearly half of those persons will develop these conditions by the age of fourteen. Diagnosed mental health conditions include a variety of psychological disorders including anxiety, addiction/substance abuse, bipolar disorder, various forms of depression, post- traumatic stress disorder, more commonly known as PTSD, schizophrenia, and suicidal thoughts among others. In more severe cases, a person may experience combinations of several of these psychological disorders. Treatment of psychological disorders currently consist of medication regimens, therapy sessions, or combinations of the two. Some of the more common types of prescribed medications include, but are not limited to, antianxiety medications; antidepressant medications to improve moods; antipsychotic medications to treat disordered thought patterns and altered perceptions, and/or mood-stabilizing medications. Given the wide range of medications typically prescribed for various psychological disorders, the efficacy of a particular medication for a particular disorder for a particular patient is highly variable. Often, identifying a safe and effective treatment for each patient is a hit or miss strategy depending on a patient’s reaction to a particular medication or dosing regimen, which can result in a patient being over, under or improperly treated for potentially extended periods of time causing unnecessary discomfort, and perhaps worse.

[0004] In addition, there are a wide range of side effects, from mild to severe, which have been observed in patients taking these various medications. As one example, a common class of antidepressants include selective serotonin reuptake inhibitors, or SSRIs. Numerous negative side effects are associated with SSRIs including, but not limited to: feeling agitated, shaky or anxious; feelings of being sick; indigestion; diarrhea or constipation; loss of appetite and weight loss; dizziness; blurred vision; dry mouth; excessive sweating; sleeping problems, including insomnia or drowsiness; headaches; reduced sex drive; difficulty achieving orgasm during sex or masturbation; and in men, difficulty obtaining or maintaining an erection; i.e., erectile dysfunction. Serotonin-norepinephrine reuptake inhibitors, or SNRIs, are another class of antidepressants that are often prescribed to treat depression as well as anxiety. Common side effects associated with SNRIs essentially parallels the side effects noted above for SSRIs. Other classes of medications often prescribed to treat persons with psychological disorders include tricyclic antidepressants and benzodiazepines, each coming with their own set of similar negative side effects, with the addition of potential addiction and/or overdose in the case of benzodiazepines.

[0005] Accordingly, there is an established need for a solution to the foregoing problems and shortcomings in the present state of the art with regard to methods of treatment for psychological disorders with medication.

DETAILED DESCRIPTION

[0033] The present disclosure is based in part on the discovery that psilocybin analogs can have different psychoactive properties. As used herein, the term “psychoactive properties or effects” refers to any change in the function of the nervous system resulting in alterations in perception, mood, consciousness, cognition, or behavior. Compounds comprising psychoactive properties can be used medically to provide a therapeutic benefit, recreationally, or spiritually; to purposefully improve performance or alter one's consciousness; as entheogens for ritual, spiritual, or shamanic purposes, or for research.

[0034] The inventors surprisingly discovered that individual psilocybin analogs can have a different psychoactive effect when administered to a subject in pure form in isolation from other psylocibin analogs that are normally present in magic mushrooms or from metabolites of the same compound. Importantly and surprisingly, the inventors also discovered that some of the psylocibin analogs in fact can worsen a psychological disorder when administered to a subject. Additionally, when a psilocybin analog of the instant disclosure exhibits psychoactive activity in addition to a beneficial therapeutic activity, the psilocybin analog can be administered at concentrations sufficiently low to provide a therapeutic effect without the non-therapeutic psychoactive effects.

I. Composition

[0035] One aspect of the present disclosure encompasses pharmaceutical compositions comprising a psilocybin analog for treating psychological disorders.

(a) Psilocybin analogs

[0036] A composition of the instant disclosure comprises a psilocybin analog. As used herein, the term “psilocybin analog” refers to psilocybin, a metabolite thereof, an analog thereof, a derivative thereof, or a psilocybin-like molecule. Psilocybin analogs are tryptamine compounds comprising an indole ring linked to an ethylamine substituent. Psilocybin is chemically related to the amino acid tryptophan and is structurally similar to the neurotransmitter serotonin (FIG. 1).

[0037] In some aspects, a psilocybin analog of the instant disclosure is a tryptamine compound of Formula I. The groups designated with an R can be varied as needed to define specific molecules in this chemical family.

Formula I [0038] In some aspects, a psilocybin analog of the instant disclosure is a tryptamine compound as set forth in Table 1 , or any combination thereof.

Table 1.

[0039] As each psilocybin analog can have different psychoactive effects when compared to another psilocybin analog, it will be recognized that a composition of the instant disclosure comprises intended one or more psilocybin analogs in a substantially pure form, absent other psylocibin analogs. Accordingly, a composition of the instant disclosure comprises no psylocibin analogs other than the one or more psilocybin analogs of the composition or comprises trace amounts of an unintended psilocybin analog at sufficiently low concentrations that do not exert non-therapeutic psychoactive effects on the subject.

[0040] Psilocybin is a naturally occurring psychedelic compound produced by more than 200 species of psychedelic fungi. The most potent are members of the genus Psilocybe, such as P. azurescens, P. semilanceata , and P. cyanescens. Psylocybins, analogs thereof, derivatives thereof, and psilocybin-like molecules are abundant in nature and can also be found in mushrooms from the genus Conocybe, Copelandia, Galerina, Gymnopilus, Inocybe, Panaeolus, Pholiotina , Pluteus as well as many fungi, plant species, bacteria, and animals, including mammals. For instance, bufotenine is a psilocybin-like compound found in the skin of psychoactive toads.

[0041] A psilocybin analog of the instant disclosure can be a naturally occurring psilocybin analog compound or a synthetic psilocybin analog that may not occur in nature. The psilocybin analog can be extracted and purified from a natural source or can be chemically synthesized. Methods of extracting and purifying psilocybin analogs are known in the art and can be as described in WO2021253116, the entire contents of which are incorporated herein in their entirety. Individuals of skill in the art will also be familiar with methods of chemical synthesis of a psilocybin analog compound. [0042] Compositions of the instant disclosure can comprise one or more than one psilocybin analog. When a composition comprises more than one psilocybin analog, the activity of each psilocybin can be the same or different from the activity of another psilocybin analog in the composition. For instance, a composition of the instant disclosure can comprise a psilocybin analog having anxiolytic effects, and another psilocybin analog exhibiting anti-depressive activity. Alternatively, more than one psilocybin analog can have the same therapeutic psychoactive activity and exert an additive or synergistic therapeutic effect. Accordingly, a composition of the instant disclosure can comprise 1 , 2, 3, 4, 5, 6, 7, 8, 9m, 10 or more psilocybin analogs.

[0043] Many psilocybin analogs present in natural sources can be in a phosphorylated form or a dephosphorylated form, although other non- phosphorylatable psychoactive alkaloids may also be present. In general, when the phosphorylated forms of the compounds are consumed (whether in the raw mushroom, purified extracts, or synthetic preparations of the compounds), the phosphorylated analogues are enzymatically metabolized by the human gut, liver, and kidneys to the active dephosphorylated forms. For instance, the phosphorylated pro-drug forms of psilocybin ([3-(2-Dimethylaminoethyl)-1 H-indol-4-yl] phosphate), norbaeocystin, baeocystin and aeruginascin are metabolized to the active dephosphorylated forms psilocin, 4- hydroxytryptamine, norpsilocin and 4-hydroxy- N,N,N-trimethyltryptamine, respectively (Table 2). Accordingly, a psilocybin analog in a composition of the instant disclosure can be the phosphorylated pro-drug form or the active dephosphorylated form. The psilocybin analogs can also be in other pro drug forms that can be used to improve how the drug is absorbed, distributed, metabolized, and excreted (ADME).

[0044] Psilocybin analogs can also be metabolized to generate other compounds that can have the same or different psychoactive activities or pharmacokinetic characteristics. A non-limiting example of the metabolism of a psilocybin analog is shown in FIG. 2. Since psilocin is structurally related to the neurotransmitter serotonin (FIG. 1 and FIG. 2), it undergoes comparable human metabolism. Indeed, psilocin is then further metabolized by a demethylation and oxidative deamination catalyzed by liver monoamine oxidase (MAO) or aldehyde dehydrogenase, via a presumed intermediate metabolite, 4-hydroxyindole-3- acetaldehyde, to yield 4-hydroxyindole-3-acetic acid, 4-hydroxy-indole-3- acetaldehyde and 4-hydroxytryptophole. It was also described a minor oxidation metabolic pathway of psilocin to a deep blue color product with an o-quinone or iminoquinone structure. This pathway was claimed to be catalyzed by hydroxyindol oxidases (e.g., ceruloplasmin, the copper containing oxidase of mammalian plasma and cytochrome oxidase) or non-enzymatically by Fe ³⁺ .

[0045] Monoamine oxidase inhibitors (MAOI) have been known to prolong and enhance the effects of DMT and one study assumed that the effect on psilocybin would be similar since it is a structural analogue of DMT. Alcohol consumption may enhance the effects of psilocybin, because acetaldehyde, one of the primary breakdown metabolites of consumed alcohol, reacts with biogenic amines present in the body to produce MAOIs related to tetrahydroisoquinoline and b-carboline. Tobacco smokers may also experience more powerful effects with psilocybin, because tobacco smoke exposure decreases the activity of MAO in the brain and peripheral organs.

[0046] In some aspects, the composition of the instant disclosure comprises baeocystin. In other aspects, the composition of the instant disclosure comprises norpsilocin. As explained herein above, baeocystin is the phosphorylated form of norpsilocin. The inventors surprisingly discovered that compositions comprising baeocystin or norpsilocin have anxiolytic activity and no harmful psychoactive effects, including no depressive activity. Baeocystin is a zwitterionic alkaloid and analog of psilocybin. It is found as a minor compound in most psilocybin mushrooms together with psilocybin, norbaeocystin, and psilocin. Baeocystin is an N-demethylated derivative of psilocybin. Reports on the hallucinogenic activities of baeocystin are conflicting.

(b) Compositions [0047] Compositions of the instant disclosure can be formulated in dosage unit formulations containing conventional nontoxic pharmaceutically acceptable adjuvants, excipients, and vehicles as desired. Formulation of pharmaceutical compositions is discussed in, for example, Hoover, John E., Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pa. (1975), and Liberman,

B. Encapsulation

[0069] A composition of the instant disclosure can comprise a psilocybin analog encapsulated in a drug vehicle. As used herein, the term “encapsulated” refers to an active ingredient such as a psilocybin analog of the instant disclosure encapsulated in a drug carrier or drug vehicle. A wide variety of drug delivery systems have been developed and studied, each of which has unique advantages and disadvantages. Non-limiting examples of drug vehicles include liposomes, polymeric micelles, microspheres, and nanoparticles among others. Different methods of attaching the drug to the carrier have been implemented, including adsorption, integration into the bulk structure, encapsulation, and covalent bonding. Different types of drug vehicles utilize different methods of attachment, and some vehicles can even implement a variety of attachment methods.

[0070] Non-limiting examples of nanoparticles include nano diamonds, nanofibers, protein-DNA complexes, protein-drug complexes, protein-drug conjugates, erythrocytes, virosomes, and dendrimers. Encapsulating drug compounds such as psilocybin analogs of the instant disclosure can provide numerous benefits such as increasing the stability and life of the compound being encapsulated, facilitate the manipulation of the product, and provide for the controlled release of the contents.

[0071] Polymeric micelles are drug vehicles formed by the aggregation of some amphiphilic molecules with an amphiphilic block copolymer These vehicles form at some high concentration specific to the compounds used, called the critical micelle concentration. The addition of an amphiphilic block copolymer effectively lowers this critical micelle concentration by shifting the monomer exchange equilibrium.

[0072] Microspheres are hollow, micron-sized vehicles often formed via self- assembly of polymeric compounds which are most often used to encapsulate the active drug for delivery. Drug release from microspheres is often achieved by diffusion through pores in the microsphere structure or by degradation of the microsphere shell. Some assembly techniques, such as precision particle fabrication (PPF), can create microspheres capable of sustained control over drug release.

[0073] Liposomes are artificially spherical vesicles prepared from naturally derived phospholipid. They entail one or more lipid bilayers with discrete aqueous spaces. They are well established for a range of pharmaceutical and biomedical applications with the unique capability of entrapment of both hydrophilic (polar) and hydrophobic (nonpolar) compounds due to their amphipathic nature in aqueous media. For instance, hydrophobic compounds entrap in the bilayer membrane, while hydrophilic compounds encapsulate in the aqueous core. Liposomes serve as DDSs due to their versatile structure; biocompatibility; and the fact they are naturally nontoxic, non-immunogenic, and biodegradable. Liposomes have several advantages contributing to drug delivery. They have a role enhancing drug solubility, serving as a sustained release system, providing targeted drug delivery, reducing the toxic effect of drugs, providing protection against drug degradation, enhancing circulation half-life of APIs, being effective in overcoming multidrug resistance, improving the therapeutic index of the entrapped drug, and protecting APIs against their surrounding environment.

[0074] Numerous factors define liposomes properties such as the lipid composition, number of lipid bilayers, size, surface charge, and the method of preparation. Liposomal vesicles vary in size between 0.025 pm to 2.5 pm. They can be categorised according to the number of their layers (also referred to as lamellae): unilamellar (consisting of single phospholipid bilayer) or multilamellar (consisting of more than one unilamellar separated by layers of water (>500 nm)). Unilamellar vesicles are subdivided into small unilamellar vesicles (20-100 nm) and large unilamellar vesicles (>100 nm). Both the size and the number of lamellae in the liposomal structure are considered to be the most crucial factors affecting the vesicles half-life and the quantity of API that is to be encapsulated. This unique and flexible variety in the liposomal structure distinguishes liposomes as the preferred carriers for a broad spectrum of therapeutic agents.

[0075] Physical and chemical stability of the liposomes in terms of size distribution, entrapment efficiency, and minimal degradation of liposomal apparatuses is the major limiting step for drug delivery using this system. Chemical degradation of liposomes mainly occurs at the phospholipid bilayers level, in which two different reactions might develop: (i) hydrolysis of the ester bonds between fatty acids and glycerol backbone, and (ii) peroxidation of any available unsaturated acyl chain. These two reactions might lead to the development of short-chain lipids; subsequently, soluble derivatives will appear in the membrane that would significantly reduce the quality and stability of the liposomal system. With respect to physical instability, liposomes might undergo aggregation/flocculation and fusion/coalescence, which can ultimately change vesicle size and lead to significant loss of the encapsulated API. [0076] Several factors that have an influence on liposomal system stability, such as liposomal composition (e.g., phospholipids-lipids with high phase transition temperatures), fatty acid side-chains, polar head chemistry, chain length, and the degree of unsaturation, can maintain liposomal rigidity and phospholipid:cholesterol molar ratio (crucial for the liposomal stability and controlling drug release).

[0077] Phospholipids are the main building blocks of liposomes. These biomolecules are also the main components building the biological membranes.

They are amphiphilic molecules that consist of a polar head (water soluble hydroxy groups) and insoluble backbone. Liposomes can be zwitterionic, positively or negatively charged, or uncharged. This is dependent on the polar head charge. There are two types of lipids currently utilized for liposome preparation: naturally occurring or synthesized double-chain lipids (consisting of phosphorus polar head and glycerol backbone) and sterols (e.g., cholesterol).

[0078] The most known lipids used in the liposomal formulations are phosphatidylcholine (zwitterionic), phosphatidylglycerol (negatively charged), phosphatidic acid, phosphatidylethanolamine (zwitterionic), and phosphatidylserine (negatively charged). Positively charged lipids (e.g., N-[1-(2,3-dioleyloxy)propyl]- N,N,N-triethylammonium (DOTMA) and 1 ,2-dioleoyl-3-trimethylammoniopropane (DOTAP)) are mainly used for gene delivery, as they interact with the negatively charged deoxyribonucleic acid (DNA) and negatively charged APIs.

[0079] Cholesterol is another strategic component of liposomes. It has a modulatory effect on the properties of the lipid bilayer of the liposomes. It can control the stoutness in the liposome structure and increase the packing between the phospholipid molecules, resulting in more ordered conformation in the aliphatic tail region, reduced micropolarity, reduced bilayer flexibility to the surrounding molecules (especially water-soluble molecules), and increases in the microviscosity of the bilayer. Cholesterol is also crucial for structural stability of liposomal membranes against intestinal environmental stress. Cholesterol was found to influence liposomes size (increasing cholesterol concentration increases liposomes size in addition to shape transition), provide permeability and fluidity, and consequently modulate the release of hydrophilic compounds from liposomes. [0080] The lipid bilayer of a liposome may fuse with other bilayers (e.g., the cell membrane), thus delivering the contents of the liposome to cells. Phospholipids generally comprise two fatty acids linked through glycerol phosphate to one of a variety of polar groups. Non-limiting examples of phospholids suitable for liposomes include phosphatidic acid (PA), phosphatidylserine (PS), phosphatidylinositol (PI), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG), phosphatidylcholine (PC), and phosphatidylethanolamine (PE), or any combination thereof.

[0081] The fatty acid chains may range from about 6 to about 26 carbon atoms in length, and the lipid chains may be saturated or unsaturated. Non-limiting examples of suitable fatty acid chains include (common name presented in parentheses) n-dodecanoate (laurate), n-tetradecanoate (myristate), n- hexadecanoate (palmitate), n-octadecanoate (stearate), n-eicosanoate (arachidate), n-docosanoate (behenate), n-tetracosanoate (lignocerate), cis-9-hexadecenoate (palmitoleate), cis-9-octadecanoate (oleate), cis,cis-9,12-octadecandienoate (linoleate), all-cis-9,12,15-octadecatrienoate (linolenate), and all-cis-5,8, 11 ,14- eicosatetraenoate (arachidonate). The two fatty acid chains of a phospholipid may be identical or different. Acceptable phospholipids include dioleoyl PS, dioleoyl PC, distearoyl PS, distearoyl PC, dimyristoyl PS, dimyristoyl PC, dipalmitoyl PG, stearoyl.oleoyl PS, palmitoyl.linolenyl PS, and any combination thereof.

[0082] The phospholipids can come from any natural source, and, as such, may comprise a mixture of phospholipids. For example, egg yolk is rich in PC, PG, and PE, soy beans contains PC, PE, PI, and PA, and animal brain or spinal cord is enriched in PS. Phospholipids may come from synthetic sources too. Mixtures of phospholipids having a varied ratio of individual phospholipids may be used.

Mixtures of different phospholipids may result in liposome compositions having advantageous activity or stability of activity properties. The above mentioned phospholipids may be mixed, in optimal ratios with cationic lipids, such as N-(1-(2,3- dioleolyoxy)propyl)-N,N,N-trimethyl ammonium chloride, 1 ,1’-dioctadecyl-3,3,3’,3’- tetramethylindocarbocyanine perchloarate, 3,3’-diheptyloxacarbocyanine iodide, 1 ,1’- didodecyl-3,3,3’,3’- tetramethylindocarbocyanine perchloarate, 1 ,T-dioleyl-3,3,3’,3’- tetramethylindo carbocyanine methanesulfonate, N,4-(dilinoleylaminostyryl)-N- methylpyridinium iodide, or 1 ,1-dilinoleyl-3,3,3’,3’-tetramethylindocarbocyanine perchloarate.

[0083] Liposomes can optionally comprise sphingolipids, in which spingosine is the structural counterpart of glycerol and one of the one fatty acids of a phosphoglyceride, or cholesterol, a major component of animal cell membranes. Liposomes may optionally, contain pegylated lipids, which are lipids covalently linked to polymers of polyethylene glycol (PEG). The PEGylated lipids may generally increase the amount of compound that can be incorporated into the liposomes.

PEGs may range in size from about 500 to about 10,000 Daltons. A suitable PEGylated phospholipid is dipalmitoyl PE bearing PEG 5,000.

[0084] Liposomes can further comprise a suitable solvent. The solvent may be an organic solvent or an inorganic solvent. Suitable solvents include, but are not limited to, dimethylsulfoxide (DMSO), methylpyrrolidone, N-methylpyrrolidone, acetronitrile, alcohols, dimethylformamide, tetrahydrofuran, or combinations thereof.

[0085] Liposomes carrying the psilocybin analogs of the instant disclosure can be prepared by any known method of preparing liposomes for drug delivery, such as, for example, detailed in U.S. Pat. Nos. 4,241 ,046, 4,394,448, 4,529,561 , 4,755,388, 4,828,837, 4,925,661 , 4,954,345, 4,957,735, 5,043,164, 5,064,655, 5,077,211 and 5,264,618, and Verrico et al., PAIN, 2020 Sep 1 ; 161 (9): 2191-2202, the disclosures of which are hereby incorporated by reference in their entirety. For example, liposomes can be prepared by sonicating lipids in an aqueous solution, solvent injection, lipid hydration, reverse evaporation, or freeze drying by repeated freezing and thawing. The liposomes can be multilamellar, which have many layers like an onion, or unilamellar.

[0086] As would be apparent to one of ordinary skill, all the parameters that govern liposome formation may be varied. These parameters include, but are not limited to, temperature, pH, concentration of active pharmaceutical ingredient, concentration and composition of lipid, concentration of multivalent cations, rate of mixing, presence of and concentration of solvent.

(b) Administration

[00102] A composition of the instant disclosure can be administered to a subject by several different means. For instance, a composition can generally be administered parenterally, buccally, nasally, by inhalation, intraperitoneally, intravascularly, transdermally, subcutaneously, rectally, or intrapulmonarily. The term parenteral as used herein includes subcutaneous, intravenous, intramuscular, intrathecal, or intrasternal injection, or infusion techniques. Topical administration may also involve the use of transdermal administration such as transdermal patches or iontophoresis devices. The compositions can be formulated in dosage unit formulations for administration comprising conventional nontoxic pharmaceutically acceptable adjuvants, carriers, excipients, and vehicles as described in Section l(b)(B)).

[00103] Actual dosage levels of active ingredients in a therapeutic composition of the disclosure may be varied so as to administer an amount of a psilocybin analog that is effective to achieve the desired therapeutic response for a particular subject. A selected dosage level may depend upon a variety of factors, including the psilocybin analog in a composition, the activity of the therapeutic composition, formulation, the combination with other drugs or treatments, disease and longevity, the inflammation or inflammatory disorder, and the physical condition and prior medical history of the subject being treated. Determination of the proper dosage for a particular situation is within the skill of the practitioner.

[00104] In some aspects, the composition is administered regularly by following a prescribed treatment schedule. For instance, a composition of the instant disclosure can be administered routinely, at various intervals. For instance, compositions can be administered daily, weekly, monthly, or over several months. In some aspects, compositions are administered daily. In other aspects, compositions are administered weekly. In yet other aspects, compositions are administered monthly. Compositions can also be administered every three to six months. As it will be recognized in the art, the duration of treatment can and will vary and can be determined experimentally.

[00105] Administration of the compositions described herein can also be carried out as part of a treatment regimen that may include multiple instances of administration of one or more compositions comprising psilocybin analogs. Such a regimen may be designed as a method of immediately treating a condition and/or as a method of long-term maintenance of the health of a subject after having been treated for a condition (e.g., prevention). For instance, a treatment regimen can be designed to delay the onset of the condition of interest in a subject. It will be appreciated that determination of appropriate treatment regimens is within the skill of practitioners in the art.

[00106] It will also be appreciated by those skilled in the art that a composition of the present disclosure may be co-administered with other therapeutic agents before, after, and/or during treatment with a composition of the disclosure. The term “co-administer” refers to administration of more than one active ingredient at the same time, just prior to, or just after the administration of one or more additional therapies. The compounds of the disclosure can be administered alone or can be co-administered to the patient. Co-administration is meant to include simultaneous or sequential administration of the compounds individually or in combination. Dosage amounts and intervals can be adjusted individually to provide levels of the administered compound effective for the particular clinical indication being treated. This will provide a therapeutic regimen that is commensurate with the severity of the individual's disease state.

Example 1. The impact of baeocystin, norbaeocystin, aeruginascin and norpsilocin in animal models of anxiety and depression in mice [00122] Summary. The goal of the present project was to assess psilocybin metabolites in animal models of anxiety and depression in mice. Specifically, baeocystin (0.3mg/kg-30mg/kg), norbaeocystin (0.3-3.0mg/kg), aeruginascin (0.3-3.0mg/kg) and norpsilocin (0.3-3.0 mg/kg) were tested in the open field test (OFT), elevated plus maze (EPM), tail suspension test (TST) and forced swim test (FST). Overall, most compounds were ineffective and/or increased negative behaviors. However, baeocystin (30mg/kg) in the EPM significantly increased time on the open arm and norpsilocin significantly increased time spent in the center zone of the OFT. Both of these results suggest that baeocystin and norpsilocin can exert anxiolytic effects in mice using certain behavioral procedures.

[00123] Methods. The open field test (OFT) was conducted by placing a mouse in a gray chamber 40x40 cm of 30cm height and allowed to explore at will for 30 minutes. A digital camera positioned above the chamber recorded behavior. Animals that spend more time in the center (open area) compared to along the walls (thigmotaxis) are deemed less anxious. The open field apparatus was cleaned with Peroxigard wipes after each use.

[00124] The elevated plus maze (EPM) is a behavioral assay that measures anxiety in rodents. The apparatus is composed of open and closed arms arranged in a “plus” measuring, 35cm arm length; 5cm arm width; 20cm wall height and stands 61cm height. Each mouse was placed on the maze within the center area facing towards an open arm and allowed to explore the EPM for 5 minutes.

The experimenter observed the mouse from outside the test room through an observational window. Behavior was recorded via a digital camera mounted above the maze. The apparatus was cleaned with Peroxigard wipes after each trial.

[00125] The tail-suspension test (TST) is a model of depression and has been used to screen prospective antidepressant compounds. It involves suspending mice above the ground by their tails with tape for a predetermined time. A 17 cm piece of tape was taped to the tail (2 cm of the 17 cm) of each mouse and then attached to a metal shelf for 6 minutes. Each mouse was digitally recorded and data analyzed using specialized software with particular focus on time immobile. After the trial, tape was removed and mice returned to their home cage.

[00126] The forced swim test is a classic behavioral assay to test for depressive behavior such as immobility. The apparatus is composed of a Plexiglas cylinder measuring (20cm diameter, 45cm height) that is filled with water maintained at room temperature (23-25C). During testing, mice were placed into the water by the nape of the neck facing the wall and released and behavior recorded via a digital camera for 6 minutes. After the test, mice were dried off with a towel and placed in their home cage in which half is heated by a heating pad placed underneath the cage. Fecal matter was removed after every test. Water was changed after 10 mice were run in each cylinder. After the completion of the experiment, water was drained and the cylinder cleaned with Peroxigard wipes.

[00127] Statistical analysis. Data were analyzed using a one-way ANOVA with drug dose as the primary factor. Post-hoc multiple comparison analysis was performed following significant main effects using Tukey’s multiple comparisons test (GraphPad Prism 9.2.0). Statistical significance was set at P<0.05.

[00128] Results. A total of 170 male C57BL/6 mice were used for this study (see TABLE 3.). One mouse in the diazepam group died of unknown causes. Another mouse developed a skin condition in the aeruginascin (1.0mg/kg) group and was excluded from the FST test. All other test groups consisted of N=10 per group. Statistical comparisons are noted in each figure legend. The quantitative data is shown in FIGs. 2-22.

[00129] Interpretation and conclusions. TABLE 4 summarizes the effects of the various compounds tested in the aforementioned behavioral paradigms. Results indicate, norbaeocystin and aeruginascin either produced no significant effect or a significant negative impact across all behavioral tests. None of the compounds tested showed any positive effects in the two models of depression (TST, FST). The OFT in general assesses overall gross motor activity of an animal. All compounds but norbaeocystin significantly decreased activity. A decrease in overall activity must be considered a potential confound within the context of other positive behavioral effects. Norpsilocin (3.0 mg/kg) was the only compound that increased time spent in the center zone in the OFT and this effect was highly significant. Increased time spent in the center zone is generally interpreted as an anti-anxiety effect. Further, the highest dose of baeocystin (30 mg/kg) significantly increased time spent on the open arm in the EPM assay, which is also interpreted as an anti-anxiety effect. This anti-anxiety effect appeared to be dose-responsive in that the next lower dose of baeocystin (10 mg/kg) also tended to increase time spent on the open arms however, this did not reach statistical significance. The EPM is a classic behavioral paradigm that has strong predictive validity. That is, compounds producing significant anti-anxiety effects in the EPM show similar effects in humans. Doses of baeocystin and norpsilocin tested translate to 170.1 mg and 17.0 mg/day respectively for a 70 kg human and are within the scope of clinical application. This is the first series of studies to assess these compounds in animal models of anxiety and depression thus comparisons to previous studies is not possible.
