[0101] How to use

[0102] Hypertension is the most common chronic disease, affecting 1.13 billion people worldwide and causing 10 million deaths annually. Despite the existence of antihypertensive drugs that have successfully lowered blood pressure (BP) in millions of patients, some significant needs remain unmet. Only half of people with hypertension have their blood pressure controlled, and in a large proportion, current antihypertensive drugs do not restore normal blood pressure. Treatment-resistant hypertension (TRH), also known as refractory hypertension, is on the rise due to the increasing prevalence of diabetes and obesity (which account for up to 75% of hypertension risk and the majority of TRH cases). Identifying new targets and developing new strategies to prevent and treat hypertension and its complications remains a high priority in public health and healthcare.

[0172] The term "carrier" refers to an excipient or medium with which a compound is applied, including but not limited to diluents, disintegrants, precipitation inhibitors, surfactants, flow aids, binders, lubricants, etc. Pharmaceutically acceptable carriers are generally described in this article and in EWMartin's "Remington's Pharmaceutical Sciences". Examples of carriers include, but are not limited to, aluminum monostearate, aluminum stearate, carboxymethyl cellulose, sodium carboxymethyl cellulose, crospovidone, glyceryl isostearate, glyceryl monostearate, hydroxyethyl cellulose, hydroxyethyl cellulose, hydroxymethyl cellulose, hydroxyoctadecyl hydroxystearate, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, lactose, lactose monohydrate, magnesium stearate, mannitol, microcrystalline cellulose, poloxamer 124, poloxamer 181, poloxamer 182, poloxamer 188, poloxamer 237, poloxamer 407, povidone, silica, colloidal silica, silicone, silicone binder 4102, and silicone emulsions. However, it should be understood that the carriers selected for the pharmaceutical composition and the amounts of these carriers in the composition can vary depending on the formulation method (e.g., dry granulation formulation, solid dispersion formulation).

[0173] Some examples of suitable excipients for oral formulations include lactose, dextrose, sucrose, sorbitol, mannitol, starch, gum arabic, calcium phosphate, alginate, tragacanth gum, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup, and methylcellulose. The formulation may also contain: lubricants such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifiers and suspending agents; preservatives such as methylparaben and propylparaben; sweeteners; and flavoring agents.

[0174] As used herein, "pharmaceuticalally acceptable excipients" are pharmaceutically acceptable media, including but not limited to any and all carriers, solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic agents, and absorption delay agents. The use of such media and agents for pharmaceutically active substances is well known in the art. Except for those incompatible with the active ingredient, any conventional media or agent is intended for use in therapeutic compositions. Complementary active ingredients may also be incorporated into the composition.

[0175] The pharmaceutical composition may be administered in single or multiple doses via any acceptable mode of administration of an agent having similar efficacy, such as as described in those patents and patent applications incorporated herein by reference, including rectal, buccal, intranasal and transdermal routes, via intra-arterial injection, intravenous, intraperitoneal, parenteral, intramuscular, subcutaneous, oral, local administration, as an inhalant, or via an impregnated or coated device, such as, for example, a stent or arterial insertion cylindrical polymer.

[0176] One mode of administration is parenteral administration, particularly injection. Compounds of Formula I or their pharmaceutically acceptable salts or cocrystals can be incorporated for injection in the form of aqueous or oily suspensions or emulsions containing sesame oil, corn oil, cottonseed oil, or peanut oil, as well as elixirs, mannitol, dextrose, or sterile aqueous solutions, and similar drug carriers. Saline solutions are also routinely used for injection. Ethanol, glycerol, propylene glycol, liquid polyethylene glycol, etc. (and suitable mixtures thereof), cyclodextrin derivatives, and vegetable oils can also be used. For example, by using coatings such as lecithin, in the case of dispersions, appropriate flowability can be maintained by maintaining the desired particle size, and by using surfactants. Microbial action can be prevented by various antibacterial and antifungal agents, such as parabens, chlorobutanol, phenol, sorbic acid, thimerosal, etc.

[0177] Sterile injectable solutions are prepared by incorporating the required amount of the compound according to this disclosure, along with various other ingredients listed above, into a suitable solvent, followed by filtration and sterilization. Typically, dispersions are prepared by incorporating various sterile active ingredients into a sterile medium containing a basic dispersion medium and other desired ingredients from those listed above. In the case of sterile powders used to prepare sterile injectable solutions, preferred methods of preparation include vacuum drying and freeze-drying techniques, which produce powders of the active ingredient plus any additional desired ingredients (from their previous sterile filtered solution). In some embodiments, for parenteral administration, sterile injectable solutions are prepared containing a therapeutically effective amount, such as 0.1 mg to 1000 mg of a compound of formula I or a pharmaceutically acceptable salt or cocrystal thereof. However, it should be understood that the amount of compound actually administered will generally be determined by the physician based on relevant circumstances, including the condition to be treated, the chosen route of administration, the compound actually administered and its relative activity, the age, weight and response of the individual subject, the severity of the subject's symptoms, etc.

[0178] Oral administration is another route of administration for a compound of formula I or a pharmaceutically acceptable salt or cocrystal thereof. It can be administered via capsules or enteric-coated tablets, etc. In preparing pharmaceutical compositions comprising a compound of formula I or a pharmaceutically acceptable salt or cocrystal thereof, the active ingredient is typically diluted with an excipient and / or encapsulated in a carrier, which may be in the form of capsules, pouches, paper, or other containers. When the excipient is used as a diluent, it can be in the form of a solid, semi-solid, or liquid material (as described above), serving as a medium, carrier, or medium for the active ingredient. Therefore, compositions can be in the following forms: tablets, pills, powders, lozenges, pouches, capsules, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft gelatin capsules and hard gelatin capsules, sterile injectable solutions, and sterile packaged powders.

[0179] In some embodiments, for parenteral administration, each dose unit contains 0.1 mg to 1 g, 0.1 mg to 700 mg, or 0.1 mg to 100 mg of a compound of formula (I) or a pharmaceutically acceptable salt or cocrystal thereof. In some embodiments, a therapeutically effective amount or pharmacologically effective amount of a compound of formula (I) or a pharmaceutically acceptable salt thereof comprises about 0.1 mg to about 500 mg per dose, administered once or twice daily. In some embodiments, the individual dose is selected from 1 mg, 5 mg, 10 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, 75 mg, 100 mg, 150 mg, 200 mg, 250 mg, 300 mg, 350 mg, 400 mg, and 500 mg per dose.

[0180] However, for any dosage unit described herein, it should be understood that the actual amount of compound administered will generally be determined by the physician based on relevant circumstances, including the condition to be treated, the chosen route of administration, the compound actually administered and its relative activity, the individual subject's age, weight and response, and the severity of the subject's symptoms.

[0181] Products and reagent kits

[0182] Compositions comprising, for example, formulations and unit doses, of compounds of formula I' or formula I, or pharmaceutically acceptable salts or cocrystals thereof, can be prepared and placed in suitable containers and labeled for the treatment of specified symptoms.

In some implementations, the disease or symptom indicated on the label may include, for example, treatment for cancer.

[0183] definition

[0184] Terms such as “microvascular tone,” “microcirculatory tone,” “microcirculatory vascular tone,” and “arteriolar tone” refer to the degree of contraction experienced by microcirculatory vessels relative to their maximum dilated state. Anatomically, the microcirculation can be defined as vessels with a diameter between approximately 250 μm and approximately 100 μm, particularly including vessels with a diameter between approximately 200 μm and approximately 150 μm, which include arterioles, capillaries, and venules (postcapillary venules). These vessels can be collectively referred to as “microvessels,” “microcirculatory vessels,” etc. In the embodiments described herein, the objective is to provide compounds, compositions, and methods for relaxing microvessels in a subject, reducing vascular resistance and protecting the microvessels themselves, and reducing or eliminating end-organ damage associated with microvascular resistance, particularly end-organ damage seen in the eyes, kidneys, and heart, as well as damage to nerve sheaths associated with microvessels. In some embodiments, the microcirculation is defined as vessels with a diameter <200 μm. In the human body, approximately 90% of blood volume is contained in these blood vessels, including arterioles, capillaries, and venules. Arterioles range in diameter from approximately 50 to 200 μm. Some venules contain vascular smooth muscle, while some capillaries are surrounded by pericytes, both of which are contractile cells that allow these vessels to constrict and relax, thereby delivering more or less blood and oxygen to the cells and removing cellular waste. The size of these arterioles is strictly regulated to meet the oxygen demands of the cells they supply.

[0185] Coronary microvascular disease is a heart condition that affects the walls and lining of the tiny blood vessels branching off from the larger coronary arteries. It is also known as "cardiac syndrome X" or "non-obstructive coronary heart disease." In the heart or other parts of the body, it can also be called "small artery disease," "small vessel disease," or "arteriosclerosis of the small arteries."

[0186] Such small vessel diseases are common in essential hypertension, stroke, and hypertensive nephropathy. Kidney damage typically involves afferent arterioles and interlobular arteries and may involve intimal thickening, vascular smooth muscle cell proliferation, and extracellular matrix deposition, thereby increasing the media-to-lumen ratio. The areas of vascular smooth muscle cells are subsequently replaced by fibrosis and cell death.

[0187] "Microvascular angina" refers to a form of chest pain caused by abnormalities in the heart's microvessels (including but not limited to malrelaxation or spasm).

[0188] In this article, "heterocyclic" or "heterocyclic group" refers to a chemical ring containing a carbon atom and at least one cyclic heteroatom selected from O, S, and N, including saturated, unsaturated, partially saturated, and aromatic rings.

[0202] The term "halogen" refers to an atom selected from the elements chlorine, fluorine, bromine, and iodine.

[0203] The term "oxo" refers to the double bond oxygen "=O".

[0204] The terms "therapeutic effective amount" and "pharmacologically effective amount" refer to the amount sufficient to achieve the treatment as defined below when administered to a subject requiring such treatment (e.g., a mammal, such as a human). Therapeutic effective amounts or pharmacologically effective amounts will vary depending on the subject being treated and the disease condition, the subject's weight and age, the severity of the disease condition, the method of administration, etc., and can be readily determined by one of ordinary skill in the art. For example, a "therapeutic effective amount" or "pharmacologically effective amount" of a compound of formula I or a pharmaceutically acceptable salt or cocrystal thereof is an amount sufficient to antagonize GPR39 expression or activity, thereby treating a subject (e.g., a human) with the indication or improving or alleviating existing symptoms of the indication. For example, a therapeutic effective amount or pharmacologically effective amount may be an amount sufficient to alleviate symptoms of a disease or symptom that responds to inhibition of GPR39 activity.

[0205] "Treatment / treating" is a method of achieving a beneficial or desired outcome (including clinical outcomes). A beneficial or desired clinical outcome may include one or more of the following: (i) suppressing a disease or symptom (e.g., reducing one or more symptoms caused by the disease or symptom, and / or alleviating the severity of the disease or symptom); (ii) slowing or preventing the development of one or more clinical symptoms associated with the disease or symptom (e.g., stabilizing the disease or symptom, preventing or delaying the worsening or progression of the disease or symptom, and / or preventing or delaying the spread of the disease or symptom (e.g., metastasis)); and / or (iii) alleviating the disease, i.e., causing the remission of clinical symptoms (e.g., improving the disease state, providing partial or complete remission of the disease or symptom, enhancing the effect of another medication, delaying the progression of the disease, improving quality of life, and / or prolonging survival).

[0206] The term "inhibiting / inhibition" refers to a reduction in the baseline activity of a biological activity or process, such as a significant reduction. "Inhibition of GPR39 activity" refers to a reduction in GPR39 activity as a direct or indirect response to the presence of such a compound or its pharmaceutically acceptable salt or cocrystal, relative to the activity of GPR39 in the absence of a compound of Formula I or its pharmaceutically acceptable salt or cocrystal. The reduction in activity may be due to a direct interaction between the compound and GPR39, or due to the interaction of the compound described herein with one or more other factors that in turn affect the expression and / or activity of GPR39. For example, the presence of a compound can reduce GPR39 activity by directly binding to GPR39, by inducing (direct or indirect) a reduction in the expression or activity of GPR39 by another factor, or by (direct or indirect) reducing the amount of GPR39 protein present in a cell or organism. In some embodiments, the inhibition of GPR39 activity can be compared in the same subject or in other untreated subjects prior to treatment. The term “inhibitor” should be understood as a compound or agent that provides the desired inhibitory activity when administered to a person in need at a pharmaceutically or therapeutically effective dose.

[0207] "Delaying" the development of a disease or condition refers to postponing, hindering, slowing, delaying, stabilizing, and / or postponing its progression. The duration of this delay varies depending on the history of the disease or condition and / or the subject being treated. Methods of "delaying" the development of a disease or condition involve reducing the probability of its development and / or the severity of its development within a given timeframe compared to not using such methods. These comparisons are typically based on clinical studies using statistically significant numbers of subjects. The development of a disease or condition can be detected using standard methods such as routine physical examination, mammography, imaging, or biopsy. Development can also refer to the progression of a disease or condition that may initially be undetectable, including occurrence, recurrence, and onset.

[0208] As used herein, unless the context clearly indicates otherwise, the singular terms “a” and “the” include the plural referent. Similarly, unless the context clearly indicates otherwise, the word “or” is intended to include “and”. Furthermore, as used herein, the term “comprising” means “including”. Therefore, “comprising A or B” means including A, B, or A and B.

[0209] The numerical values ​​in the specification and claims of this application should be understood to include the same numerical values ​​when reduced to the same number of significant figures and numerical values ​​whose difference from the stated values ​​is less than the experimental error of conventional measurement techniques of the type described in this application that determined the value.

[0210] All scopes disclosed and / or claimed herein include the stated endpoints and may be combined independently (e.g., the scopes “2 to 10” and “2-10” include endpoints 2 and 10 as well as all intermediate values ​​3, 4, 5, 6, 7, 8 and 9).

[0211] “Significant” means any detectable change that is statistically significant in a standard parametric test (such as Student’s T test) where p < 0.05.

[0212] "Pharmaceutically acceptable salts" include, for example, salts with inorganic acids and salts with organic acids. Examples of salts can include hydrochlorides, phosphates, bisphosphonates, hydrobroms, sulfates, sulfinates, nitrates, malates, maleates, fumarates, tartrates, succinates, citrates, acetates, lactates, methanesulfonates, benzenesulfonates, p-toluenesulfonates, 2-hydroxyethylsulfonates, benzoates, salicylates, stearates, and alkylates (e.g., acetates, HOOC-(CH2)). n --COOH, where n is 0-4). Furthermore, if the compound described herein is obtained as an acid addition salt, the free base can be obtained by alkalizing the solution of the acid salt. Conversely, if the product is a free base, the addition salt, particularly a pharmaceutically acceptable addition salt, can be prepared by dissolving the free base in a suitable organic solvent and treating the solution with acid, following conventional methods for preparing acid addition salts from base compounds. Those skilled in the art will recognize the various synthetic methods that can be used to prepare non-toxic, pharmaceutically acceptable addition salts.

[0213] The term "crystal form" and related terms used herein refer to various crystallization variants of a given substance, including but not limited to polymorphs, solvates, hydrates, eutectics, and other molecular complexes, as well as salts, solvates of salts, hydrates of salts, other molecular complexes of salts, and their polymorphs. The crystal form of a substance can be obtained by a variety of methods known in the art. These methods include, but are not limited to, melt recrystallization, melt cooling, solvent recrystallization, recrystallization in confined spaces such as nanopores or capillaries, recrystallization on surfaces or templates such as polymers, recrystallization in the presence of additives such as anti-molecules of eutectics, desolvation, dehydration, rapid evaporation, rapid cooling, slow cooling, vapor diffusion, sublimation, grinding, and solvent drop grinding.

[0214] As used herein, the term "co-crystal" or "co-crystal salt" refers to a crystalline material composed of two or more distinct solids at room temperature, each solid possessing unique physical properties such as structure, melting point and heat of fusion, hygroscopicity, solubility, and stability. Co-crystals or co-crystal salts can be prepared using co-crystallization methods known per se. The term co-crystal or co-crystal salt also refers to a multi-component system in which one or more host API (active pharmaceutical ingredient) molecules (e.g., Formula I compound) and one or more guest (or co-formed) molecules are present. In a particular embodiment, a pharmaceutically acceptable co-crystal of Formula I or Formula II compound and co-formed molecule is a crystalline form selected from malonic acid co-crystal, succinic acid co-crystal, decanoic acid co-crystal, salicylic acid co-crystal, vanillic acid co-crystal, maltol co-crystal, or glycolic acid co-crystal. Co-crystals may have improved properties compared to the parent form (i.e., free molecules, zwitterions, etc.) or salts of the parent compound. Improved properties may include increased solubility, increased dissolution, increased bioavailability, increased dose-response, reduced hygroscopicity, crystalline form of normally amorphous compounds, crystalline form of compounds that are difficult or impossible to salt, reduced form diversity, and more desirable forms.

[0215] As used herein, the terms “isotope” and “isotopic” with respect to compounds disclosed herein refer to the substitution of one or more atoms of a compound by an isotope of those atoms. An “isotope” is any of two or more forms of a chemical element having the same number of protons in its nucleus but different numbers of neutrons. For example, an isotopic compound includes a compound in which one or more hydrogen atoms (H) have been substituted by one or more deuterium atoms (D). In this example, deuterium is an isotope of hydrogen, and substituting hydrogen atoms (at one or more positions) with deuterium makes the resulting compound an isotopic compound. For example, and referring to formula (I), replacing the two methyl groups of the isopropyl moiety (-CH(CH3)2) with a fully deuterated methyl group (-CH(CD3)2) would result in an isotopic compound of formula (I). Besides replacing hydrogen with deuterium, other stable (non-radioactive) isotopic substitutions include replacing carbon-12 with carbon-13, while unstable (radioactive) isotopes include replacing hydrogen with tritium, replacing carbon-12 with carbon-14, and replacing iodine-127 with iodine-123 or iodine-125, etc. Therefore, all references herein to isotopic compounds of formula (I), and all references to their various embodiments, refer to compounds having one or more isotopic substitutions, including (but not limited to) one or more hydrogen atoms being replaced by one or more deuterium atoms, and any occurrence in the compound. For this reason, the isotopic compounds disclosed herein offer improved advantages relative to their non-isotopic forms. Isotopic modification thus provides a means to improve existing drugs and / or serves as a tool for designing new drugs. For example, isotopic drug design has proven successful in terms of the kinetic isotopic effects of deuterium (D). Because D has twice the mass of H, the CD bond is more resistant to oxidation processes (e.g., its ability to be catalyzed by CYP450 or other enzymes involved in metabolism), while maintaining very similar spatial properties. Therefore, electronic substitutions such as HD often preserve the pharmacodynamics of compounds while improving their pharmacokinetics, affecting half-life and / or area under the curve, and ultimately dose and / or dosing regimens. For example, drug exposure can be increased through isotopic modification and / or reduced clearance. Such benefits are provided to the compounds disclosed herein through their isotopic derivatization.

[0216] Terms such as “subject” and “patient” refer to animals, such as mammals, that are already or will be the subjects of treatment, observation, or experimentation. The methods described herein are applicable to human treatment and veterinary applications. In some embodiments, the subject is a mammal; in some embodiments, the subject is a human; and in some embodiments, the subject is selected from cats and dogs. “Subject in need thereof” or “person in need” refers to a subject who may have or is suspected of having a disease or condition that would benefit from certain treatments, such as a human; for example, treated with a compound of formula I described herein or a pharmaceutically acceptable salt or cocrystal thereof. This includes subjects who can be identified as being at risk or susceptible to such a disease or condition, such that treatment could prevent the development of the disease or condition.

[0217] The term "prediabetes" or "prediabetic condition" refers to a condition in which a subject's blood glucose levels are not high enough to be considered diabetes, but may be a precursor to type 2 diabetes. A prediabetic condition can be defined in a subject as a fasting blood glucose level of 100 mg / dL or higher, but below 126 mg / dL (the diagnostic level for diabetes). Hemoglobin A1c (HbA1c) levels are another laboratory test for diabetes. An HbA1c level of 6.5% or higher is characteristic of diabetes, while a level of 5.7% to 6.4% suggests prediabetes.

[0223] Fluorescence was monitored throughout the entire measurement run. Ca 2+ The peak value of the stimulus (minus the baseline) was expressed as the percentage of maximum inhibition of the EC90C3 response, and plotted against the concentration of the test compound. Curve fitting and IC50 estimation were performed using a four-parameter logistic model with XLfit software.
