[0002] Modulators of the 5-hydroxytryptamine 2A receptor (5-HT2AR) are sought after as potential medicines for a wide range of mental and neurological disorders and conditions, including but not limited to depression, anxiety disorders, post-traumatic stress disorder, obsessive-compulsive disorder, substance abuse, eating disorders, migraines and / or cluster headaches, Alzheimer's disease, Parkinson's disease, and various inflammatory disorders, cardiovascular disorders, and / or pain disorders. While many 5-HT2AR modulators have been developed, few are more selective for this receptor than the 5-HT2B receptor, a toxicological antitarget strongly associated with related subtypes, such as drug-induced valvular heart disease.

[0003] Therefore, there is a need to develop safe and effective compounds that are 5-HT2A receptor modulators, for example, modulators that exhibit selective functionality of the 5-HT2A receptor and / or binding to the 5-HT2A receptor relative to the 5-HT2B receptor. [Overview of the Initiative]

Compounds contained in this composition, including basic or acidic moieties, can also form pharmaceutically acceptable salts with a variety of amino acids. The compounds of this disclosure may contain both acidic and basic groups, for example, one amino group and one carboxylic acid group. In such cases, the compounds can exist as acid addition salts, zwitterions, or base salts.

[0034] The compounds of this disclosure may contain one or more chiral centers and therefore may exist as stereoisomers. As used herein, the term “stereoisomer” encompasses all enantiomers or diastereomers. These compounds may be denoted by the symbols “(+)”, “(-)”, “R” or “S” depending on the arrangement of substituents around the stereogenic carbon atom, but those skilled in the art will recognize that the structure may imply a chiral center. This disclosure encompasses various stereoisomers and mixtures thereof of these compounds. Mixtures of enantiomers or diastereomers may be nominally designated as “(±)”, but those skilled in the art will recognize that the structure may imply a chiral center.

[0035] The compounds of this disclosure may contain one or more double bonds and therefore may exist as geometric isomers arising from the arrangement of substituents around a carbon-carbon double bond. [ka] This indicates a bond that may be a single, double, or triple bond as described herein. Substituents around a carbon-carbon double bond are designated as being in a "Z" or "E" configuration, and the terms "Z" and "E" are used according to IUPAC standards. Unless otherwise specified, structures exhibiting a double bond encompass both "E" and "Z" isomers. Alternatively, substituents around a carbon-carbon double bond may be referred to as "cis" or "trans," where "cis" represents a substituent on the same side of the double bond and "trans" represents a substituent on the opposite side of the double bond.

[0036] The compounds of this disclosure may contain carbocyclic or heterocyclic rings and therefore may exist as geometric isomers arising from the arrangement of substituents around the ring. The arrangement of substituents around a carbocyclic or heterocyclic ring is designated as being in a "Z" or "E" configuration, and the terms "Z" and "E" are used in accordance with IUPAC standards. Unless otherwise specified, structures exhibiting a carbocyclic or heterocyclic ring encompass both "Z" and "E" isomers. Substituents around a carbocyclic or heterocyclic ring may also be called "cis" or "trans," the term "cis" refers to substituents on the same side of the ring plane, and the term "trans" refers to substituents on opposite sides of the ring plane. A mixture of compounds in which substituents are located on both the same and opposite sides of the ring plane is called "cis / trans."

[0037] The individual enantiomers and diastereomers of the compounds of this disclosure can be prepared synthetically from commercially available starting materials containing chiral or stereocenters, or by the preparation of racemic mixtures followed by resolution methods well known to those skilled in the art. These resolution methods are exemplified by (1) binding of the enantiomer mixture to a chiral auxiliary, separation of the resulting diastereomer mixture by recrystallization or chromatography and liberation of the optically pure product from the auxiliary, (2) salt formation using an optically active resolving agent, (3) direct separation of the optical enantiomer mixture on a chiral liquid chromatography column, or (4) kinetic resolution using stereoselective chemical or enzymatic reagents. The racemic mixture can also be separated into its component enantiomers by well known methods such as chiral phase liquid chromatography or crystallization of the compound in a chiral solvent. Stereoselective synthesis, which is a chemical or enzymatic reaction in which a single reactant forms a heterogeneous mixture of stereoisomers during the formation of a new stereocenter or the transformation of an existing stereocenter, is well known in the art. Stereoselective synthesis encompasses both enantioselective and diastereoselective transformations and may include the use of chiral auxiliaries. See, for example, Carreira and Kvaerno, Classics in Stereoselective Synthesis, Wiley-VCH:Weinheim, 2009.

[0038] The compounds disclosed herein can exist in solvated and non-solvated forms with pharmaceutically acceptable solvents such as water, ethanol, etc., and this disclosure is intended to encompass both solvated and non-solvated forms. In one embodiment, the compound is amorphous. In one embodiment, the compound is a single polymorph. In another embodiment, the compound is a mixture of polymorphs. In another embodiment, the compound is in crystalline form.

[0039] This disclosure also encompasses isotopically labeled compounds of this disclosure that are identical to those recited herein, except that one or more atoms are replaced by atoms having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into the compounds of this disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, and chlorine, for example, 2 H, 3 H, 13 C, 14 C, 15 N, 18 O, 17 O, 31 P, 32 P, 35 S, 18 F and 36 Cl. For example, the compounds of this disclosure can have one or more H atoms substituted with deuterium.

[0040] Certain isotopically labeled disclosed compounds (e.g., 3 H and 14 C labeled ones) are useful in compound and / or substrate tissue distribution assays. Tritium labeling (i.e., 3 H) and carbon-14 (i.e., 14 C) isotopes are particularly preferred due to the ease of their preparation and detectability. Further, deuterium (i.e., 2Substitution with heavier isotopes such as H) may confer certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or decreased required dosage), and may thus be preferred in some situations. The isotopically labeled compounds of the present disclosure can generally be prepared by procedures similar to those disclosed in the examples herein by using an isotopically labeled reagent in place of the non-isotopically labeled reagent.

[0041] The term "prodrug" refers to a compound that is converted in vivo to yield the disclosed compound or a pharmaceutically acceptable salt, hydrate, or solvate of that compound. The conversion can occur by various mechanisms (e.g., esterases, amidases, phosphatases, oxidative and / or reductive metabolism) at various sites (e.g., within the intestinal lumen or upon passage through the intestine, blood, or liver). Prodrugs are well known in the art (see, e.g., Rautio, Kumpulainen, et al., Nature Reviews Drug Discovery 20, 7, 255). For example, if the compound of the present disclosure or a pharmaceutically acceptable salt, hydrate, or solvate of that compound contains a carboxylic acid functional group, the prodrug can be formed by replacing the hydrogen atom of the acid group with a (C 1~8 )alkyl, (C 2~12 )alkylcarbonyloxymethyl, 1-(alkylcarbonyloxy)ethyl having 4 to 9 carbon atoms, 1-methyl-1-(alkylcarbonyloxy)-ethyl having 5 - 10 carbon atoms, alkoxycarbonyloxymethyl having 3 - 6 carbon atoms, 1-(alkoxycarbonyloxy)ethyl having 4 - 7 carbon atoms, 1-methyl-1-(alkoxycarbonyloxy)ethyl having 5 - 8 carbon atoms, N-(alkoxycarbonyl)aminomethyl having 3 - 9 carbon atoms, 1-(N-(alkoxycarbonyl)amino)ethyl having 4 - 10 carbon atoms, 3-phthalidyl, 4-crotonolactonyl, gamma-butyrolactone-4-yl, di-N,N-(C 1~2 )alkylamino(C 2~3 )alkyl (such as β-dimethylaminoethyl), carbamoyl-(C 1~2) alkyl, N,N-di(C 1~2 ) Alkylcarbamoyl-(C 1~2 ) Alkyl and piperidino-, pyrrolidino-, or morpholino (C 2~3 ) May include esters formed by substitution with groups such as alkyl groups.

[0042] Similarly, if the compound disclosed herein contains an alcohol functional group, the hydrogen atoms of the alcohol group, (C 1~6 ) Alkylcarbonyloxymethyl, 1-((C 1~6 )alkylcarbonyloxy)ethyl, 1-methyl-1-((C 1~6 )alkylcarbonyloxy)ethyl(C 1~6 ) Alkoxycarbonyloxymethyl, N-(C 1~6 ) Alkoxycarbonylaminomethyl, succinoyl, (C 1~6 ) Alkylcarbonyl, α-amino(C 1~4 Prodrugs can be formed by substitution with groups such as alkylcarbonyl, arylalkylcarbonyl, and α-aminoalkylcarbonyl, or α-aminoalkylcarbonyl-α-aminoalkylcarbonyl, where each α-aminoalkylcarbonyl group is a naturally occurring L-amino acid, P(O)(OH)2, -P(O)(O(C) 1~6 A radical independently selected from alkyl-2 or glycosyl (a radical resulting from the removal of a hydroxyl group from the hemiacetal form of a carbohydrate).

[0043] When the compounds of this disclosure incorporate amine functional groups, prodrugs can be formed, for example, by the production of amides or carbamates, N-alkylcarbonyloxyalkyl derivatives, (oxodioxolenyl)methyl derivatives, N-Mannich bases, imines, or enamines. Furthermore, secondary amines can be metabolically cleaved to produce biologically active primary amines, or tertiary amines can be metabolically cleaved to produce biologically active primary or secondary amines. See, for example, Simplicio, et al., Molecules 2008, 13, 519 and the references therein.

Such kits include appropriate dosage forms, such as those described above, and instructions describing how to use such dosage forms to mediate, alleviate, or prevent inflammation. The instructions will instruct consumers or healthcare professionals to administer the dosage forms according to dosage forms known to those skilled in the art. Such kits may be advantageously packaged and sold in single or multiple kit units. An example of such a kit is a so-called blister pack. Blister packs are well known in the packaging industry and are widely used for packaging pharmaceutical unit dosage forms (tablets, capsules, etc.). Blister packs generally consist of a sheet of relatively rigid material covered with a foil, preferably made of clear plastic material. During the packaging method, a recess is formed in the plastic foil. The recess has the size and shape of the tablet or capsule to be packaged. The tablet or capsule is then placed in the recess, and the sheet of relatively rigid material is sealed against the plastic foil with the foil side opposite to the direction in which the recess was formed. As a result, the tablet or capsule is sealed in the recess between the plastic foil and the sheet. Preferably, the sheet has sufficient strength so that a tablet or capsule can be removed from the blister pack by manually applying pressure to the recess, thereby forming an opening in the sheet at the location of the recess. The tablet or capsule can then be removed through this opening.

[0103] For example, it may be desirable to provide a memory aid in the kit in the form of a number next to a tablet or capsule, where the number corresponds to the day of the regimen in which the designated tablet or capsule should be taken. Another example of such a memory aid is a calendar printed on a card, for example, "Week 1, Monday, Tuesday, etc., Week 2, Monday, Tuesday, etc." Other variations of the memory aid will readily become apparent. The "daily dose" may be a single tablet or capsule or several pills or capsules taken on a given day. Also, the daily dose of a first compound may consist of one tablet or capsule, and the daily dose of a second compound may consist of several tablets or capsules, and vice versa. The memory aid should reflect this.
