Description

[0001] Public background Mental illnesses, including depression and anxiety, severely impair global health and human functioning. Despite the availability and widespread prescribing of various psychotropic medications, they fail to provide relief for many individuals. Even in those patients who do respond, changes in mood and behavior often appear slowly. In recent years, this persistent unmet need for improved pharmacological treatments for mental illnesses has led to consideration of previously criticized options. For example, classic serotonergic hallucinogens such as lysergic acid diethylamide (LSD), psilocybin, and dimethyltryptamine (DMT) have been considered as experimental therapies for various mental illness indications.

[0002] However, such compounds can cause strong hallucinogenic effects, suppressing normal bodily functions in individuals receiving such treatment. Therefore, due to their high potential for abuse, lack of approved medical use, and lack of proven safety, they are currently classified as Schedule I drugs under the Controlled Substances Act. These effects are largely mediated by binding to serotonin receptors. Activation of the serotonin 2A receptor (5-HT2A) is particularly important, as it is the cause of the problematic hallucinogenic activity of these compounds, but is also considered crucial to their claimed therapeutic effects. Therefore, compounds of this type that can provide therapeutic benefits while limiting hallucinogenic activity, thereby limiting the possibility of abuse and adverse reactions, would have high therapeutic value.

[0050] The various enantiomers and diastereomers of the compounds disclosed herein can be synthesized from commercially available starting materials containing asymmetric or stereocenters, or synthesized by preparing racemic mixtures followed by resolution methods well known to those skilled in the art. These resolution methods are exemplified by: (1) linking a mixture of enantiomers to a chiral auxiliary agent, separating the resulting mixture of diastereomers by recrystallization or chromatography, and releasing an optically pure product from the auxiliary agent; (2) forming a salt using an optically active resolving agent; (3) directly separating a mixture of optically enantiomers on a chiral liquid chromatography column; or (4) kinetic resolution using stereoselective chemical or enzymatic reagents. Racemic mixtures can also be resolved into their constituent enantiomers by well-known methods, such as chiral liquid chromatography or crystallizing the compounds in a chiral solvent. Stereoselective synthesis is a chemical or enzymatic reaction in which a single reactant forms a mixture of unequal amounts of stereoisomers in the process of creating a new stereocenter or transforming an existing stereocenter, as is well known in the art. Stereoselective synthesis encompasses enantioselective and diastereoselective transformations and may involve the use of chiral auxiliaries. See, for example, Carreira and Kvaerno. Classics in Stereoselective Synthesis , Wiley-VCH: Weinheim, 2009.

[0051] In some embodiments, the compositions prepared herein may be enriched with a specific enantiomer of any compound disclosed herein (relative to the corresponding inverse enantiomer of that compound) such that the mixture is not racemic. In this case, the mixture of isomers should be understood as having an enantiomer excess and optical purity >0%.

[0107] V. Description of the compound The compounds of formula (I) contain seven variables: R1, R2, R3, R4, R5, R6, and R7. This disclosure does not describe all combinations and permutations of these different variables with respect to the compounds of each formula (I). However, all these compounds of formula (I) and their pharmaceutically acceptable salts are part of and included within the scope of this disclosure.

[0108] Furthermore, all compounds of formula (I) and their pharmaceutically acceptable salts, as well as miscellaneous compounds and their pharmaceutically acceptable salts, contain a chiral center and can therefore exist in a variety of stereoisomers. These various stereoisomers, including enantiomers and diastereomers, existing in substantially pure forms and mixtures thereof (including racemic and non-racemic mixtures), are part of and included within the scope of this disclosure. In embodiments, any compound disclosed herein containing one or more chiral centers may be its pure enantiomer (R or S) or diastereomer.

[0109] Salts of the compounds disclosed herein can be prepared by reacting the compounds of this disclosure with a suitable acid or base in a suitable solvent or mixture of solvents (e.g., ether, such as diethyl ether, or alcohol, such as ethanol, or an aqueous solvent) using conventional steps. Salts of the compounds of this disclosure can be exchanged for other salts by processing with conventional ion-exchange chromatography procedures or by reforming a free base or free acid and subsequently reacting it with an alternative acid or base, respectively.

[0110] If a specific enantiomer of the compounds of this disclosure is required, it can be generated from a mixture of the corresponding enantiomers by employing any suitable conventional method for resolving enantiomers. For example, diastereomeric derivatives (e.g., salts) can be generated by reacting a mixture of enantiomers of the compounds of this disclosure (e.g., racemic mixtures) with a suitable chiral compound (e.g., a chiral acid). The diastereomers can then be separated by any conventional means (e.g., crystallization), and the desired enantiomers can be recovered (e.g., by treatment with a base if the diastereomer is an acidic salt). Alternatively, a racemic mixture of esters can be resolved by kinetic hydrolysis using various biocatalysts (e.g., see Patel Stereoselective Biocatalysts, Marcel Decker; New York 2000).

[0111] In another separation method, racemic mixtures of the disclosed compounds can be separated using chiral high-performance liquid chromatography. Alternatively, specific enantiomers can be obtained by using a suitable chiral intermediate in one of the methods described above. If it is desired to obtain specific diastereomers, regioisomers, or geometric isomers of the disclosed compounds, chromatography, recrystallization, and other conventional separation procedures can also be used for intermediates or final products.

For example, appropriate flowability can be maintained by using coating materials (e.g., lecithin), by maintaining the desired particle size in the case of dispersants, and by using surfactants.

[0127] On the other hand, this disclosure provides an enteric pharmaceutical formulation comprising a compound or miscellaneous compound of formula (I) and an enteric-coated material; and a pharmaceutically acceptable carrier or excipient thereof. An enteric-coated material is a polymer that is substantially insoluble in the acidic environment of the stomach but is primarily soluble in intestinal fluid at a specific pH. The small intestine is the part of the digestive tract (intestinal tract) between the stomach and the large intestine, comprising the duodenum, jejunum, and ileum. The pH of the duodenum is approximately 5.5, the pH of the jejunum is approximately 6.5, and the pH of the terminal ileum is approximately 7.5. Therefore, for example, enteric materials dissolve only at pH values ​​of approximately 5.0, 5.2, 5.4, 5.6, 5.8, 6.0, 6.2, 6.4, 6.6, 6.8, 7.0, 7.2, 7.4, 7.6, 7.8, 8.0, 8.2, 8.4, 8.6, 8.8, 9.0, 9.2, 9.4, 9.6, 9.8, or 10.0. Exemplary enteric materials include cellulose acetate phthalate (CAP), hydroxypropyl methylcellulose phthalate (HPMCP), polyvinyl acetate phthalate (PVAP), hydroxypropyl methylcellulose acetate succinate (HPMCAS), cellulose trimellitate, hydroxypropyl methylcellulose succinate, cellulose acetate succinate, cellulose acetate hexahydrophthalate, cellulose propionate phthalate, cellulose acetate maleate, cellulose acetate butyrate, cellulose acetate propionate, copolymers of methyl methacrylate and methyl methacrylate, methyl acrylate, copolymers of methyl methacrylate and methacrylate, copolymers of methyl vinyl ether and maleic anhydride (Gantrez ES series), ethyl methacrylate-methyl methacrylate-ethyl chlorotrimethylammonium acrylate copolymers, natural resins (e.g., zein, shellac, and copalcollophorium), and several commercially available enteric dispersion systems (e.g., Eudragit L30D55, Eudragit FS30D, Eudragit...). L100, Eudragit S100, Kollicoat EMM30D, Estacryl 30D, Coateric, and Aquateric. The solubility of each of the above materials is known or readily determined in vitro. The foregoing is a list of possible materials, but those skilled in the art who benefit from this disclosure will recognize that it is not exhaustive and that there are other enteric-coated materials that satisfy the purposes of this disclosure.

[0128] The pharmaceutical compositions described herein may also have immediate-release, delayed-release, sustained-release, or modulated-release properties. In embodiments, pharmaceutical compositions with different drug release properties can be combined to create two-phase or three-phase release characteristics. For example, a pharmaceutical composition may have both immediate-release and sustained-release properties. In embodiments, a pharmaceutical composition may have both sustained-release and delayed-release properties. Such compositions may be provided as pulsatile formulations, multilayer tablets, or capsules containing tablets, beads, granules, etc.

[0129] Pharmaceutical compositions may also contain one or more excipients. Excipients (also referred to as auxiliary ingredients) include any additional conventional substances in the art, such as fillers, binders, diluents, disintegrants, lubricants, colorants, flavorings, antioxidants, and wetting agents. Such excipients are appropriately selected relative to the intended form and route of administration and in accordance with standard pharmaceutical practice.

[0130] This disclosure also provides, for example, kits for consumers who require treatment with compounds of formula (I) and / or miscellaneous compounds. Such kits include a suitable dosage form (e.g., those described above) and instructions describing the method of using such dosage form to treat a medical condition (e.g., a mental illness or disease). The instructions instruct the user to administer the dosage form according to methods of administration known to those skilled in the art. Such kits can advantageously be packaged and sold in single or multiple kit units. An example of such kits is the so-called blister pack. Blister packs are well-known in the packaging industry and are widely used for packaging unit dosage forms of pharmaceuticals (tablets, capsules, etc.). Blister packs typically consist of a relatively rigid sheet of material covered with a foil, preferably a transparent plastic material. During the packaging process, grooves are formed on the plastic foil. The grooves have the size and shape of the tablets or capsules to be packaged. The tablets or capsules are then placed in the grooves, and the relatively rigid sheet of material is sealed to the plastic foil on the surface of the foil (opposite to the direction in which the grooves are formed). Thus, the tablets or capsules are sealed in the grooves between the plastic foil and the sheet. Preferably, the sheet is strong enough that tablets or capsules can be removed from the blister pack by manually applying pressure to the groove to create an opening in the sheet at the groove location. The tablets and capsules can then be removed through said opening.

[0131] Providing memory aids on the kit may be desirable, for example, in the form of numbers next to the tablets or capsules, according to which these numbers correspond to the dates of the treatment regimen on which the specified tablets or capsules should be taken. Another example of such a memory aid is a calendar printed on a card, for example, as follows: "Week 1, Monday, Tuesday, ... etc. Week 2, Monday, Tuesday, ... etc." Other variations of memory aids will be apparent. A "daily dose" can be a single tablet or capsule taken on a specified day or multiple pills or capsules. Furthermore, the daily dose of the first compound can consist of a single tablet or capsule, while the daily dose of the second compound can consist of multiple tablets or capsules, and vice versa. The memory aid should reflect this.

[0132] This article also considers methods and compositions that include or apply a second active ingredient.

[0133] Purpose and usage The compounds and hybrid compounds of formula (I) disclosed herein are agonists of the 5-HT2A receptor. In embodiments, the compounds and / or hybrid compounds of formula (I) selectively bind to and activate the 5-HT2A receptor.

[0180] The following non-limiting embodiments further illustrate the teachings of this disclosure.

[0181] In the following examples, several compounds were prepared in substantially enantiomerically pure form by separating racemic mixtures of the compounds themselves or synthetic intermediates (which were then converted into the compounds while retaining the same absolute stereochemistry at the chiral center) via chiral supercritical fluid chromatography (SFC). The enantiomerically pure compounds prepared in this manner are designated as enantiomer 1 (E1) or enantiomer 2 (E2), where these terms respectively denote the first and second eluted enantiomers from the illustrated chiral SFC method. However, the absolute stereochemistry of these enantiomerically pure compounds was not determined experimentally, and therefore, in the context of the examples, designating E1 or E2 as R or S stereochemistry in the drawn scheme should be considered arbitrary.
