MIXED SEROTONIN RECEPTOR BINDERS FOR TREATMENT OF PSYCHOTIC DISORDERS CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No.63 / 614,457, filed December 22, 2023, and U.S. Provisional Application No.63 / 735,148, filed December 17, 2024, each of which is incorporated herein by reference in its entirety. FIELD OF THE INVENTION
[0002] Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments comprising such compounds, and methods of using such compounds for the treatment of conditions, diseases, or disorders. BACKGROUND
[0003] Over the last several decades, predominant interest in serotonergic targets with respect to schizophrenia has centered around 5-HT2A antagonism / inverse agonism.5-HT2C receptor agonists have emerged as additional serotonergic target of interest.5-HT2C agonists have been suggested as treatments for multiple symptom domains of schizophrenia including positive, negative, cognitive, and depressive symptoms without the adverse events or tolerability issues associated with existing agents. The 5-HT2C receptor is a highly complex, highly regulated receptor which is widely distributed throughout the brain. The 5-HT2C receptor couples to multiple signal transduction pathways leading to engagement of a number of intracellular signaling molecules. Moreover, there are multiple allelic variants of the 5-HT2C receptor and the receptor is subject to RNA editing in the coding regions. The complexity of this receptor is further emphasized by the utility of either agonists or antagonists in the treatment of schizophrenia. The preclinical profile of 5-HT2C agonists from a neurochemical, electrophysiological, and a behavioral perspective is indicative of antipsychotic-like efficacy. Selective 5-HT2C agonist vabicaserin demonstrated clinical efficacy in a Phase II trial in schizophrenia patients. These data suggest that 5-HT2C agonists are potential therapeutics for the treatment of psychiatric disorders, including psychotic disorders. SUMMARY

[0023] The term “carbocyclic” or “carbocycle” refers to a ring or ring system where the atoms forming the backbone of the ring are all carbon atoms. The term thus distinguishes carbocyclic from “heterocyclic” rings or “heterocycles” in which the ring backbone contains at least one atom which is different from carbon. In some embodiments, at least one of the two rings of a bicyclic carbocycle is aromatic. In some embodiments, both rings of a bicyclic carbocycle are aromatic. In certain embodiments, a carbocyclyl comprises three to ten carbon atoms. In other embodiments, a carbocyclyl comprises five to seven carbon atoms. The carbocyclyl is attached to the rest of the molecule by a single bond. Carbocyclyl or cycloalkyl is saturated (i.e., containing single C-C bonds only) or unsaturated (i.e., containing one or more double bonds or triple bonds). Examples of saturated cycloalkyls include, e.g., cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, and cyclooctyl. An unsaturated carbocyclyl is also referred to as "cycloalkenyl."

[0034] The term “acceptable” with respect to a formulation, composition or ingredient, as used herein, means having no persistent detrimental effect on the general health of the subject being treated.
[0035] The term “modulate” as used herein, means to interact with a target either directly or indirectly so as to alter the activity of the target, including, by way of example only, to enhance the activity of the target, to inhibit the activity of the target, to limit the activity of the target, or to extend the activity of the target. In some embodiments, “modulate” means to interact with a target either directly or indirectly so as to decrease or inhibit receptor activity. In some embodiments. modulation is an increase or decrease in the amount, quality, or effect of a particular activity, function or molecule. By way of illustration and not limitation, agonists, partial agonists, antagonists, and allosteric modulators (e.g., a positive allosteric modulator) of a G protein-coupled receptor are modulators of the receptor.
[0036] The term “modulator” as used herein, refers to a molecule that interacts with a target either directly or indirectly. The interactions include, but are not limited to, the interactions of an agonist, partial agonist,an inverse agonist, antagonist, or combinations thereof. In some embodiments, a modulator is an antagonist. Receptor antagonists are inhibitors of receptor activity. Antagonists mimic ligands that bind to a receptor and prevent receptor activation by a natural ligand. Preventing activation may have many effects. If a natural agonist binding to a receptor leads to an increase in cellular function, an antagonist that binds and blocks this receptor decreases the function of the receptor.
[0037] The term “agonism,” as used herein, generally refers to the activation of a receptor or enzyme by a modulator, or agonist, to produce a biological response.
[0038] The term “agonist,” as used herein, generally refers to a modulator that binds to a receptor or enzyme and activates the receptor to produce a biological response. In some embodiments, the term “agonist” includes full agonists or partial agonists. “Full agonist” refers to a modulator that binds to and activates a receptor with the maximum response that an agonist can elicit at the receptor. “Partial agonist” refers to a modulator that binds to and activates a given receptor, but has partial efficacy, that is, less than the maximal response, at the receptor relative to a full agonist.
[0039] The term “positive allosteric modulator,” as used herein, generally refers to a modulator that binds to a site distinct from the orthosteric binding site and enhances or amplifies the effect of an agonist.
[0040] The term “antagonism,” as used herein, generally refers to the inactivation of a receptor or enzyme by a modulator, or antagonist. Antagonism of a receptor, for example, is when a molecule binds to the receptor and blocks function of the receptor.
[0041] The term “antagonist” or “neutral antagonist,” as used herein, generally refers to a modulator that binds to a receptor or enzyme and blocks a biological response. An antagonist may have no activity in the absence of an agonist or inverse agonist but can block the activity of either, causing no change in the biological response.
[0042] The terms "administer," "administering", "administration," and the like, as used herein, refer to the methods that may be used to enable delivery of compounds or compositions to the desired site of biological action. These methods include, but are not limited to oral routes, intraduodenal routes, parenteral injection (including intravenous, subcutaneous, intraperitoneal, intramuscular, intravascular or infusion), topical and rectal administration. Those of skill in the art are familiar with administration techniques that can be employed with the compounds and methods described herein. In some embodiments, the compounds and compositions described herein are administered orally.
[0043] The terms “effective amount” or “therapeutically effective amount,” as used herein, refer to a sufficient amount of an agent or a compound being administered, which will relieve to some extent one or more of the symptoms of the disease or condition being treated. The result includes reduction and / or alleviation of the signs, symptoms, or causes of a disease, or any other desired alteration of a biological system. For example, an “effective amount” for therapeutic uses is the amount of the composition comprising a compound as disclosed herein required to provide a clinically significant decrease in disease symptoms. An appropriate “effective” amount in any individual case is optionally determined using techniques, such as a dose escalation study.
[0044] The term “subject” or “patient” encompasses mammals. Examples of mammals include, but are not limited to, any member of the Mammalian class: humans, non-human primates such as chimpanzees, and other apes and monkey species; farm animals such as cattle, horses, sheep, goats, swine; domestic animals such as rabbits, dogs, and cats; laboratory animals including rodents, such as rats, mice and guinea pigs, and the like. In one embodiment, the mammal is a human.
[0045] The terms “treat,” “treating” or “treatment,” as used herein, include alleviating, abating or ameliorating at least one symptom of a disease or condition, preventing additional symptoms, inhibiting the disease or condition, e.g., arresting the development of the disease or condition, relieving the disease or condition, causing regression of the disease or condition, relieving a condition caused by the disease or condition, or stopping the symptoms of the disease or condition either prophylactically and / or therapeutically.
[0046] The term “pharmaceutically acceptable,” as used herein, generally refers a material, such as a carrier or diluent, which does not abrogate the biological activity or properties of the compound, and is relatively nontoxic, i.e., the material is administered to an individual without causing undesirable biological effects or interacting in a deleterious manner with any of the components of the composition in which it is contained.
[0047] The term “pharmaceutically acceptable salt,” as used herein, generally refers to a form of a therapeutically active agent that consists of a cationic form of the therapeutically active agent in combination with a suitable anion, or in alternative embodiments, an anionic form of the therapeutically active agent in combination with a suitable cation. Handbook of Pharmaceutical Salts: Properties, Selection and Use. International Union of Pure and Applied Chemistry, Wiley-VCH 2002. S.M. Berge, L.D. Bighley, D.C. Monkhouse, J. Pharm. Sci.1977, 66, 1-19. P. H. Stahl and C. G. Wermuth, editors, Handbook of Pharmaceutical Salts: Properties, Selection and Use, Weinheim / Zürich:Wiley-VCH / VHCA, 2002. Pharmaceutical salts typically are more soluble and more rapidly soluble in stomach and intestinal juices than non-ionic species and so are useful in solid dosage forms. Furthermore, because their solubility often is a function of pH, selective dissolution in one or another part of the digestive tract is possible and this capability can be manipulated as one aspect of delayed and sustained release behaviors. Also, because the salt-forming molecule can be in equilibrium with a neutral form, passage through biological membranes can be adjusted. Provided herein are non-hallucinogenic compounds that promote neuronal growth and / or improve neuronal structure. Compounds

Further or alternatively, the prodrug also has improved solubility in pharmaceutical compositions over the parent drug. In some embodiments, the design of a prodrug increases the effective water solubility. An example, without limitation, of a prodrug is a compound described herein, which is administered as an ester (the “prodrug”) but then is metabolically hydrolyzed to provide the active entity. A further example of a prodrug is a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharmaceutically or therapeutically active form of the compound.
