Description

[Technical Field]

[0001] This application relates generally to compounds, and in particular to compounds that modulate the biological activity of PD-L1 protein. [Background technology]

[0002] Programmed death-ligand 1 (PD-L1) is a protein that plays a key role in suppressing the adaptive arm of the immune system. Normally, the adaptive immune system responds to antigens associated with immune system activation by exogenous or endogenous danger signals. This is followed by the proliferation of clonal expansion of antigen-specific CD8+ T cells and / or CD4+ helper cells. Binding of PD-L1 to the inhibitory checkpoint molecule PD-1 on T cells delivers an inhibitory signal that reduces the proliferation of antigen-specific T cells in lymph nodes and simultaneously reduces the apoptosis of regulatory T cells (anti-inflammatory, suppressor T cells).

[0003] Molecules that can modulate PD-L1 activity may therefore have broad application in the treatment of various disease states. Summary of the Invention

[0007] Reference will now be made in detail to certain aspects and exemplary embodiments of the present application, examples of which are illustrated in the accompanying structures and figures. While aspects of the present application will be described in conjunction with exemplary embodiments, including methods, materials, and examples, such description is not intended to be limiting, and the scope of the present application is intended to encompass all equivalents, alternatives, and modifications that are commonly known or incorporated herein. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. Those skilled in the art will recognize many techniques and materials similar or equivalent to those described herein, which can be used in the practice of aspects and embodiments of the present application. The described aspects and embodiments of the present application are not limited to the methods and materials described. As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise.

[0008] Ranges may be expressed herein as from "about" one particular value, and / or to "about" another particular value. When such a range is expressed, another embodiment includes from the one particular value and / or to the other particular value. Similarly, when values ​​are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant in relation to the other endpoint, as well as independently of the other endpoint. It is also understood that there are a number of values ​​disclosed herein, and that each value is also herein disclosed as "about" that particular value in addition to the value itself. For example, if the value "10" is disclosed, "about 10" is also disclosed. It is also understood that when a value is disclosed, "less than or equal to" "greater than or equal to" the value, and possible ranges between the values ​​are also disclosed, as appropriately understood by one of ordinary skill in the art. For example, if the value "10" is disclosed, "less than or equal to 10" and "greater than or equal to 10" are also disclosed.

[0009] At various places in the present specification, particular features of compounds are disclosed in groups or ranges, and such disclosure is specifically intended to include every individual subcombination of the members of such groups and ranges.

[0010] The compounds described herein can be asymmetric (e.g., having one or more stereocenters). All stereoisomers, such as enantiomers and diastereomers, are intended unless otherwise specified. Compounds of the present application containing asymmetrically substituted carbon atoms can be isolated in optically active or racemic forms. Methods for preparing optically active forms from optically inactive starting materials are known in the art, such as resolution of racemic mixtures or stereoselective synthesis. Many geometric isomers of olefins, C=N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present application. Cis and trans geometric isomers of the compounds of the present application are described and can be isolated as a mixture of isomers or as separated isomeric forms.

[0011] Resolution of racemic mixtures of compounds can be achieved by any of a number of methods known in the art. One method involves fractional recrystallization using a chiral resolving acid, which is an optically active, salt-forming organic acid. Suitable resolving agents for fractional recrystallization include, for example, optically active acids such as D- and L-tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, and lactic acid, or various optically active camphorsulfonic acids, such as β-camphorsulfonic acid. Other resolving agents suitable for fractional crystallization include stereomerically pure forms (e.g., S- and R-forms, or diastereomerically pure forms) of α-methylbenzylamine, 2-phenylglycinol, norephedrine, ephedrine, t-methylephedrine, cyclohexylethylamine, 1,2-diaminocyclohexane, and the like.

[0012] Resolution of racemic mixtures can also be achieved by elution on a column packed with an optically active resolving agent (e.g., dinitrobenzoylphenylglycine). Suitable elution solvent compositions can be determined by those skilled in the art.

[0013] In compounds with two or more chiral centers, unless otherwise indicated, each chiral center in the compound can independently be either (R) or (S).

[0014] The compounds of the present application also include tautomeric forms. Tautomeric forms result from the interchange of a single bond with an adjacent double bond and the accompanying migration of a proton. Tautomeric forms include prototropic tautomers, which are isomeric protonation states with the same empirical formula and total charge. Examples of prototropic tautomers include ketone-enol pairs, amide-imidic acid pairs, lactam-lactim pairs, enamine-imine pairs, and cyclic forms in which protons can occupy more than one position on the heterocyclic ring system (e.g., 1H- and 3 / f-imidazole, 1H-, 2H- and 4H-1,2,4-triazole, H- and 2H-isoindole, and 1H- and 2 / / -pyrazole). Tautomeric forms can exist in equilibrium or can be sterically locked into one form by appropriate substitution.

[0015] The compounds of the present application may also include all isotopes of atoms present in the intermediates or final compounds. Isotopes include atoms with the same atomic number but different mass numbers. For example, isotopes of hydrogen include tritium and deuterium. One or more constituent atoms of the compounds of the present application may be replaced or substituted with a naturally or non-naturally occurring isotope of the atom. In some embodiments, the compounds contain at least one deuterium atom. For example, one or more hydrogen atoms in the compounds of the present disclosure may be replaced or substituted with deuterium. In some embodiments, the compounds contain two or more deuterium atoms.

[0017] All compounds and pharmaceutically acceptable salts thereof can be found together with or isolated from other substances, such as water and solvents (e.g., hydrates and solvates). When in the solid state, the compounds described herein and their salts can exist in various forms, for example, in the form of solvates, including hydrates. The compounds can be in any solid state form, such as polymorphs or solvates, and therefore, unless otherwise specified, references herein to compounds and salts thereof should be understood to encompass any solid state form of the compound.

[0018] In some embodiments, the compounds of the present application or salts thereof are substantially isolated. By "substantially isolated," it is meant that the compound is at least partially or substantially separated from the environment in which it was formed or detected.

[0022] The present application also includes pharmaceutically acceptable salts of the compounds described herein. The term "pharmaceutically acceptable salts" refers to derivatives of the disclosed compounds, in which the parent compound is modified by converting an existing acid or base moiety into its salt form. Examples of pharmaceutically acceptable salts include, but are not limited to, inorganic or organic acid salts of basic residues such as amines, alkali or organic salts of acidic residues such as carboxylic acids, and the like. The pharmaceutically acceptable salts of the present application include non-toxic salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. The pharmaceutically acceptable salts of the present application can be synthesized from the parent compound containing a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or free base form of these compounds with a stoichiometric amount of the appropriate base or acid in water or an organic solvent, or a mixture of the two; generally, non-aqueous media such as ether, ethyl acetate, alcohol (e.g., methanol, ethanol, isopropanol, or butanol), or acetonitrile (MeCN) are preferred. Lists of suitable salts are found in Pharmaceutical Sciences, 17th Ed., (Mack Publishing Company, Easton, 1985), p. 1418, Berge et al., J. Pharm.

[0193] In some embodiments, the compositions are manufactured using a wet granulation process. In some embodiments, the compositions are manufactured using a dry granulation process.

[0194] The compositions can be formulated in unit dosage form, each dosage containing from about 5 to about 1,000 mg (1 g), more usually about 100 mg to about 500 mg, of the active ingredient. In some embodiments, each dosage contains about 10 mg of the active ingredient. In some embodiments, each dosage contains about 50 mg of the active ingredient. In some embodiments, each dosage contains about 25 mg of the active ingredient. The term "unit dosage form" refers to physically discrete units suitable as unitary administration for human subjects and other mammals, each unit containing a predetermined quantity of the active material calculated to produce the desired therapeutic effect, together with suitable pharmaceutical excipients.

[0195] The ingredients used to formulate pharmaceutical compositions are of high purity and substantially free of potentially harmful contaminants (e.g., at least national food grade, generally at least analytical grade, and more typically at least pharmaceutical grade). For human consumption in particular, compositions are preferably manufactured or formulated in accordance with good manufacturing practice as defined in applicable regulations of the U.S. Food and Drug Administration. For example, suitable formulations may be sterile and / or substantially isotonic and / or in full compliance with all U.S. Food and Drug Administration good manufacturing practice regulations.

[0196] The active compound may be effective over a wide dosage range and is generally administered in a therapeutically effective amount. However, it will be understood that the amount of compound actually administered will usually be determined by the physician according to the relevant circumstances, including the condition to be treated, the selected route of administration, the compound actually administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, etc.

[0197] Therapeutic dosages of the compounds of the present application may vary depending, for example, on the particular application for which the treatment is given, the method of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of the compound of the present application in a pharmaceutical composition may vary depending on many factors, including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the present application may be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w / v of the compound for parenteral administration. Some typical dosage ranges are about 1 pg to about 1 g per kg of body weight per day. In some embodiments, the dosage range is about 0.01 mg to about 100 mg per kg of body weight per day. The dosage may depend on variables such as the type and progression of the disease or disorder, the overall health of the particular patient, the relative biological availability of the selected compound, the excipient formulation, and its route of administration. Effective doses may be extrapolated from dose-response curves derived from in vitro or animal model test systems.

[0198] To prepare solid compositions such as tablets, the primary active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of the compounds of the present application. When these preformulation compositions are referred to as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into similarly effective unit dosage forms, such as tablets, pills, and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above, containing, for example, from about 0.1 to about 1000 mg of the active ingredient of the present application.

[0199] The tablets or pills of the present application can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which resists disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, including many polymeric acids and mixtures of polymeric acids with materials such as shellac, cetyl alcohol, and cellulose acetate.

[0200] Liquid forms into which the compounds and compositions of the present application can be incorporated for oral or injectable administration include aqueous solutions, suitably flavored syrups, aqueous or oily suspensions, and flavored emulsions including edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

[0201] Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable aqueous or organic solvents, or mixtures thereof, and powders. Liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described above. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. The compositions can be nebulized using an inert gas. Nebulized solutions can be inhaled directly from the nebulizing device, or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices that deliver the formulation in an appropriate manner.

[0202] Topical formulations can include one or more conventional carriers. In some embodiments, ointments can include water and one or more hydrophobic carriers selected from, for example, liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white petrolatum, etc. Cream carrier compositions can be based on water in combination with glycerol and one or more other ingredients, such as glyceryl monostearate, PEG-glyceryl monostearate, and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, appropriately combined with other ingredients such as glycerol and hydroxyethylcellulose. In some embodiments, topical formulations include at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2, or at least about 5% by weight of a compound of the present application. Topical formulations can be suitably packaged, for example, in 100g tubes, optionally accompanied by instructions for the treatment of a selected indication, such as psoriasis or other skin conditions.

[0203] The amount of compound or composition administered to a patient will vary depending on what is being administered, the purpose of the administration, such as prophylaxis or treatment, the condition of the patient, the method of administration, etc. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. The effective dose will depend on the disease state being treated and the judgment of the attending physician, depending on factors such as the severity of the disease, the age, weight, and general condition of the patient, etc.

[0204] The compositions administered to patients may be in the form of pharmaceutical compositions described above. These compositions may be sterilized by conventional sterilization techniques or may be sterile filtered. Aqueous solutions may be packaged for immediate use or lyophilized, with the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound formulations is typically 3-11, more preferably 5-9, and most preferably 7-8. It will be understood that the use of certain of the aforementioned excipients, carriers, or stabilizers may result in the formation of pharmaceutical salts.

[0205] Therapeutic dosages of the compounds of the present application may vary depending, for example, on the particular application for which the treatment is given, the method of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of the compound of the present application in a pharmaceutical composition may vary depending on many factors, including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the present application may be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w / v of the compound for parenteral administration. Some typical dosage ranges are about 1 pg to about 1 g per kg of body weight per day. In some embodiments, the dosage range is about 0.01 mg to about 100 mg per kg of body weight per day. The dosage may depend on variables such as the type and progression of the disease or disorder, the overall health of the particular patient, the relative biological availability of the selected compound, the excipient formulation, and its route of administration. Effective doses may be extrapolated from dose-response curves derived from in vitro or animal model test systems.

[0366] Example 14 PD-1 / PD-L1 homogeneous time-resolved fluorescence (HTRF) binding assay

[0367] Assays were performed in standard black 384-well polystyrene plates with a final volume of 20 μL. Inhibitors were first serially diluted in DMSO and then added to the plate wells prior to the addition of other reaction components. The final concentration of DMSO in the assay was 1%. Assays were performed at 25°C in PBS buffer (pH 7.4) containing 0.05% Tween-20 and 0.1% BSA. Recombinant human PD-L1 protein (19-238) with a C-terminal His tag was purchased from AcroBiosystems (PD1-H5229). Recombinant human PD-1 protein (25-167) with a C-terminal Fe tag was also purchased from AcroBiosystems (PD1-H5257). PD-L1 and PD-1 proteins were diluted in assay buffer, and 10 μL was added to the plate wells. The plate was centrifuged, and the proteins were pre-incubated with the inhibitors for 40 minutes. Following incubation, 10 μL of HTRF detection buffer supplemented with Fe-specific europium cryptate-labeled anti-human IgG (PerkinElmer-AD0212) and anti-His antibody conjugated to SureLight® allophycocyanin (APC, PerkinElmer-AD0059H) was added. After centrifugation, the plate was incubated at 25°C for 60 minutes and then read on a PHERAstar FS plate reader (665 nm / 620 nm ratio). Final concentrations in the assay were 3 nM PD1, 10 nM PD-L1, 1 nM europium anti-human IgG, and 20 nM anti-His-allophycocyanin. IC was determined by curve fitting of percent control activity versus the logarithm of inhibitor concentration. 50 Measurements were carried out.
