Cross-Reference to Related Applications

[001] This application claims priority to U.S. Provisional Application No. 63/653,320, filed on May 30, 2024; the disclosure of which is incorporated herein by reference.

Technical Field

[002] This disclosure relates to /V-(2-(4-hydroxy-lH-indol-3-yl)ethyl)-/V-isopropylpropan-2-arninium 4- carboxybutanoate (4-hydroxy-A/,/V-diisopropyltryptaminium hydroglutarate or 4-HO-DiPT hydroglutarate), crystalline 4-HO-DiPT hydroglutarate, and specific crystalline forms thereof, including crystalline form 1 of 4-HO-DiPT hydroglutarate; to pharmaceutical compositions containing 4-HO-DiPT hydroglutarate or crystalline 4-HO-DiPT hydroglutarate, including crystalline form 1 of 4-HO-DiPT hydroglutarate; and to methods of treatment/therapeutic uses of 4-HO-DiPT hydroglutarate or crystalline 4-HO-DiPT hydroglutarate, including crystalline form 1 of 4-HO-DiPT hydroglutarate.

Background of the Invention

[003] Obtaining specific salts or crystalline forms of an active pharmaceutical ingredient (API) is extremely useful in drug development. It permits better characterization of the drug candidate's chemical and physical properties. Crystalline forms often have better chemical and physical properties than the API in its amorphous state. Such crystalline forms may possess more favorable pharmaceutical and pharmacological properties or be easier to process. Additionally, preparing a crystalline API and solving its crystal structure provides the gold standard for chemical characterization and determining the molecular formula (and molecular weight) of the API. Accordingly, preparing a crystalline form with an accompanying crystal structure thereof prevents potential ambiguities and/or inaccuracies in the API's molecular weight. This is important because the API's molecular weight is used to calculate the concentration of compositions comprising that API. Thus, inaccuracies in molecular weight may lead to errors in the calculations pertaining to dosing, potency, toxicity, etc. in all downstream in vitro and in vivo assays that correlated the concentration of the API with a measured property. Accordingly, there remains a need to obtain and characterize crystalline forms of APIs, such as tryptamines and other psychedelic drug compounds. Summary of the Invention

Exemplary MAPKs include, but are not limited to, Tropomyosin Receptor Kinase A (TrkA), P38-alpha, and c-Jun N-Terminal Kinase 3 (JNK3). TrkA is a high affinity catalytic receptor of nerve growth factor (NGF) protein. TrkA regulates NGF response, influencing neuronal differentiation and outgrowth as well as programmed cell death. p38-alpha is involved with the regulation of pro-inflammatory cytokines, including TNF-a. In the central nervous system, p38-alpha regulates neuronal death and neurite degeneration, and it is a common target of Alzheimer's disease therapies. JNK3 is a neuronal-specific protein isoform of the JNKs. It is involved with the regulation of apoptosis. JNK3 also plays a role in modulating the response of cytokines, growth factors, and oxidative stress.
