Description
Cross-reference to related applications:
this application claims priority to the citation of a chinese patent application No. 201810203812.4, earlier filed on the filing date 2018.03.13 of the chinese national intellectual property office, the entire contents of which are incorporated herein by reference.
The invention discloses a small molecular compound used as an inhibitor of PD-1/PD-L1 protein interaction, a preparation method thereof, a pharmaceutical composition and application, and belongs to the field of medicines.
Background
With the continuous development of social economy, the gradual improvement of the living standard of people, the change of the dietary structure of residents, the aging of population, urbanization, continuous deterioration of environment and other factors, the disease spectrum and the death spectrum of China are obviously changed, and the incidence of malignant tumors is on a continuously rising trend. Malignant tumors have become the first killer which is harmful to human life and health and restricts social and economic development. With the improvement of medical technology level, despite the continuous innovation of human anti-tumor methods, most tumor patients are relieved and even cured by the currently clinically applied operations, chemotherapy, radiotherapy and newly appeared molecular targeted drug treatment, but some patients still have poor sensitivity to the above treatment means and poor prognosis. Immunotherapy offers a long-lasting therapeutic effect compared to other types of tumor therapy, and has gradually shifted from initial non-specific immunotherapy to specific immune-targeted therapy. In recent decades, the milestone success of immune checkpoint inhibitors and chimeric antigen receptor T cell therapies has pushed tumor immunity to become an effective cancer treatment means following surgery, radiotherapy, chemotherapy and targeted therapy.
The mechanism of immunotherapy is to activate specific T cells, target and attack to eliminate tumor cells, and activate the anti-tumor immune system response in the body of a patient. T cell activation is primarily referred to as "dual signal" intervention, i.e., the first signal is provided by the antigenic peptide-major histocompatibility complex and the T cell antigen receptor complex, CD28Costimulatory molecules such as B7 provide second messengers for T cell activation. When the synergistic stimulation molecule is absent, the imbalance of T cell response is easily caused, so that the tumor escapes the immune monitoring of the organism. As a second signal for activating T cells, activation of a programmed death receptor 1 (PD-1) and a corresponding ligand (PD-L1) signal pathway can inhibit an organism anti-tumor immune response, so that the pathway is blocked by a medicament to obviously inhibit the growth of tumors.
PD-1 is also named CD279, is an immune co-suppression molecule found in apoptotic T cell hybridoma by subtractive hybridization technology, is a type I transmembrane protein consisting of 268 amino acids, and belongs to CD28A family member. PD-1 is structurally composed mainly of an extracellular Ig V-like domain, a hydrophobic transmembrane region, and a cytoplasmic region 3 that retains an Immunoreceptor Tyrosine Inhibition Motif (ITIM) and an immunoreceptor tyrosine transformation motif (ITSM). PD-1 is not only expressed in the living The chemotransformed immune cells such as T lymphocytes, B lymphocytes, Natural Killer (NK) cells and monocytes can also be expressed on some tumor cell lines or on the surface of tumor cells. PD-L1 is a natural ligand of PD-1, and under physiological conditions, the negative signal generated by the interaction of PD-1 and PD-L1 is a 'braking' mechanism, and mainly prevents additional injury caused by excessive immune response. For example, PD-1 of peripheral autoreactive T cells interacts with PD-L1 on the surface of non-hematopoietic cells in tissues, and can suppress proliferation and cytokine secretion of the T cell population, thereby achieving an immune tolerance effect. The tumor immune process mainly occurs in the periphery, and the T cells are excited and matured by antigen presenting cells in the primary lymphatic system to show high expression of PD-1. Tumor cells are stimulated by extracellular high levels of cytokines or by sustained activation of certain pathways, which up-regulate the expression of PD-L1. Once the tumor is infiltrated by peripheral T cells, a large amount of PD-1 and PD-L1 combine to generate an excessive negative regulation signal, so that the originally active downstream signal of a T Cell Receptor (TCR) is inhibited, the T cells gradually lose energy and even die, and the tumor realizes immune escape.
Monoclonal antibody drugs targeting PD-1 were introduced in 2014 as Pembrolizumab (Merck) and Nivolumab (Nivolumab) of Bristol-Myers Squibb (BMS), respectively, for the treatment of metastatic melanoma. PD-L1 mab atezumab (Atezolizumab), developed by the roche flag gene taxol (Genentech), was approved by the FDA in the united states for the treatment of bladder cancer at month 3 of 2016 and was approved for the treatment of lung cancer at month 11 of the same year. Unlike the well-established fire in the antibody drug market, the development of small molecule immune checkpoint blockers has not presented a pattern of blowout. The small molecule inhibitors reported in the prior art comprise benzene sulfonamide compounds in Harvarsharpe subject group, 2, 6-disubstituted toluene immunomodulators disclosed in Baishimei noble and peptidomimetic molecules developed by Curis/Aurigene cooperation, wherein the IND application of the United states FDA is obtained only in 2016 and 6 months from the Curis/Aurigene cooperation, and the small molecule mimetics is currently in clinical stage.
Compared with antibody drugs, the small molecule inhibitor has controllable pharmacokinetic behavior and relatively low cost, and well makes up for the clinical defects of large molecule drugs. Therefore, the design and synthesis of the small molecule inhibitor with the blocking effect aiming at the PD-1/PD-L1 have practical significance.

The stereochemical definitions and rules used in the present invention generally follow the general definitions of S.P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E.and Wilen, S., "Stereochemistry of Organic Compounds", John Wiley & Sons, Inc., New York, 1994.
Many organic compounds exist in an optically active form, i.e., they have the ability to rotate the plane of plane polarized light. In describing optically active compounds, the prefixes D and L or R and S are used to denote the absolute configuration of a molecule with respect to one or more of its chiral centers. The prefixes d and l or (+) and (-) are the symbols used to specify the rotation of plane polarized light by the compound, where (-) or l indicates that the compound is left-handed. Compounds prefixed with (+) or d are dextrorotatory. A particular stereoisomer is an enantiomer and a mixture of such isomers is referred to as an enantiomeric mixture. A50: 50 mixture of enantiomers is referred to as a racemic mixture or racemate, which may occur when there is no stereoselectivity or stereospecificity in the chemical reaction or process.
Any asymmetric atom (e.g., carbon, etc.) of a compound disclosed herein can exist in racemic or enantiomerically enriched forms, such as the (R) -, (S) -or (R, S) -configuration. In certain embodiments, each asymmetric atom has at least 50% enantiomeric excess, at least 60% enantiomeric excess, at least 70% enantiomeric excess, at least 80% enantiomeric excess, at least 90% enantiomeric excess, at least 95% enantiomeric excess, or at least 99% enantiomeric excess in the (R) -or (S) -configuration.
Depending on the choice of starting materials and methods, the compounds of the invention may exist as one of the possible isomers or as mixtures thereof, for example as racemates and diastereomeric mixtures (depending on the number of asymmetric carbon atoms). Optically active (R) -or (S) -isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituents may be in the E or Z configuration; if the compound contains a disubstituted cycloalkyl group, the substituents of the cycloalkyl group may have cis or trans configuration.
Any resulting mixture of stereoisomers may be separated into pure or substantially pure geometric isomers, enantiomers, diastereomers, depending on differences in the physicochemical properties of the components, for example, by chromatography and/or fractional crystallization.
The racemates of any of the resulting end products or intermediates can be resolved into the optical enantiomers by known methods using methods familiar to those skilled in the art, e.g., by separation of the diastereomeric salts obtained. Racemic products can also be obtainedThe separation is performed by chiral chromatography, e.g., High Performance Liquid Chromatography (HPLC) using a chiral adsorbent. In particular, Enantiomers can be prepared by asymmetric synthesis, for example, see Jacques, et al, Enantiomers, racemes and solutions (Wiley Interscience, New York, 1981); principles of Asymmetric Synthesis (2)nd Ed.Robert E.Gawley,Jeffrey Aubé,Elsevier,Oxford,UK,2012)；Eliel,E.L.Stereochemistry of Carbon Compounds(McGraw-Hill,NY,1962)；Wilen,S.H.Tables of Resolving Agents and Optical Resolutions p.268(E.L.Eliel,Ed.,Univ.of Notre Dame Press,Notre Dame,IN 1972)；Chiral Separation Techniques:A Practical Approach(Subramanian,G.Ed.,Wiley-VCH Verlag GmbH&Co.KGaA,Weinheim,Germany,2007)。
The term "tautomer" or "tautomeric form" refers to structural isomers having different energies that can interconvert by a low energy barrier (low energy barrier). If tautomerism is possible (e.g., in solution), then the chemical equilibrium of the tautomer can be reached. For example, proton tautomers (also known as proton transfer tautomers) include interconversions by proton migration, such as keto-enol isomerization and imine-enamine isomerization. Valence tautomers (valenctautomers) include interconversion by recombination of some of the bonding electrons. A specific example of keto-enol tautomerism is the tautomerism of the pentan-2, 4-dione and 4-hydroxypent-3-en-2-one tautomers. Another example of tautomerism is phenol-ketone tautomerism. One specific example of phenol-ketone tautomerism is the tautomerism of pyridin-4-ol and pyridin-4 (1H) -one tautomers. Unless otherwise indicated, all tautomeric forms of the compounds of the invention are within the scope of the invention.

The fused heterobicyclic group may be substituted with the substituent described in the present invention.
As described herein, the substituent is attached to the ring through a bond to form a ring system, which means that the substituent can be substituted at any substitutable position on the ring. For example, formula (a) represents that the p substituents R may be substituted at any possible substituted position on the pyridine ring.
As described herein, the ring system formed by the attachment of a linker to the ring (as shown in formula b) represents that the linker may be attached to the rest of the molecule at any available position on the ring system. Formula b represents the linkage of the octahydro-cyclopenta-pyrrole ring to the rest of the molecule at any possible linkage position.
As described herein, there are two attachment points on ring C that can be attached to the rest of the molecule, for example, as shown in formula C, where either the E or E' terminus in formula C is attached to the rest of the molecule, i.e., the attachment of the two ends can be interchanged, unless explicitly stated otherwise.
The point of attachment may be attached to the rest of the molecule at any point on the ring that is attachable, as described herein, while the two ends of the attachment may be interchanged. For example, formula d represents any possible attachment location on the ring as a point of attachment, with the two ends of the attachment point being interchangeable.
In addition, unless otherwise expressly indicated, the descriptions "… and … are each independently," "… and … are each independently," and "… and … are each independently" used throughout this document are interchangeable and should be broadly construed to mean that particular items expressed between the same symbols in different groups do not affect each other, or that particular items expressed between the same symbols in the same groups do not affect each other. For example,
in N1And N2Represent the same or different atoms or groups and do not influence each other; "n 1-n 8" represent the same or different values and do not affect each other.

Specific examples of N-oxides are N-oxides of tertiary amines or N-oxides of nitrogen-containing heterocyclic nitrogen atoms. The corresponding amines can be treated with an oxidizing agent such as hydrogen peroxide or a peracid (e.g., peroxycarboxylic acid) to form the N-oxide (see Advanced Organic Chemistry, Wiley Interscience, 4 th edition, Jerry March, pages). In particular, the N-oxide may be prepared by the method of L.W.Deady (Syn.Comm.1977,7,509-514) in which an amine compound is reacted with m-chloroperoxybenzoic acid (MCPBA), for example, in an inert solvent such as DCM.
The compounds may exist in a number of different geometric isomers and tautomers and the compounds of formula (I) -formula (II) include all such forms. For the avoidance of doubt, when a compound exists as one of several geometric isomers or tautomers and only one is specifically described or shown, it is clear that all other forms are included in formula (I) -formula (II).
The term "prodrug", as used herein, represents a compound of formula (I)The compounds are converted in vivo into compounds of formula (I) -formula (II). Such conversion is effected by hydrolysis of the prodrug in the blood or by enzymatic conversion to the parent structure in the blood or tissue. The prodrug compound of the invention can be ester, and in the prior invention, the ester can be used as the prodrug and comprises phenyl ester and aliphatic (C) 1-24) Esters, acyloxymethyl esters, carbonates, carbamates and amino acid esters. For example, a compound of the present invention contains a hydroxy group, i.e., it can be acylated to provide the compound in prodrug form. Other prodrug forms include phosphate esters, such as those obtained by phosphorylation of a hydroxyl group on the parent. For a complete discussion of prodrugs, reference may be made to the following: T.Higuchi and V.Stella, Pro-drugs as Novel Delivery Systems, Vol.14 of the A.C.S.Symphosis Series, Edward B.Roche, ed., Bioreversible Carriers in Drug designs, American Pharmaceutical Association and Pergamon Press,1987, J.Rautio et al, Prodrugs: Design and Clinical Applications, Nature Review Drug Discovery,2008,7, 255-.

Formulations of the present invention include those suitable for oral, nasal, topical, buccal, sublingual, rectal, vaginal and/or parenteral administration. The formulations may conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the art of pharmacy. The amount of active ingredient that can be combined with the carrier materials to produce a single dosage form is generally that amount of the compound which produces a therapeutic effect. Generally, the amount is from about 1% to about 99% active ingredient, preferably from about 5% to about 70%, most preferably from about 10 to about 30%, in units of one percent.
The methods of making these formulations or compositions include the step of bringing into association a compound of the invention with a carrier, optionally and independently one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the compounds of the invention with liquid carriers or finely divided solid carriers or both, and then, if necessary, shaping the product.
Formulations of the present invention suitable for oral administration may be in the form of capsules, cachets, pills, tablets, lozenges (using a flavored base, typically sucrose and acacia or tragacanth), powders, granules, or solutions or suspensions in aqueous or non-aqueous liquids, or oil-in-water or water-in-oil liquid emulsions, or elixirs or syrups, or pastilles (using an inert base, such as gelatin and glycerin, or sucrose and acacia) and/or mouthwashes and the like, each containing a predetermined amount of a compound of the present invention as the active ingredient. The compounds of the invention may also be administered in the form of a bolus, electuary or paste.

Compressed tablets may be prepared with binders (for example, gelatin or hydroxypropylmethyl cellulose), lubricants, inert diluents, preservatives, disintegrating agents (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-active or dispersing agents. Molded tablets may be prepared by molding in a suitable machine a mixture of the powdered compound moistened with an inert liquid diluent.
Tablets and other solid dosage forms of the pharmaceutical compositions of the invention, such as dragees, capsules, pills and granules, can optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical art. They may also be formulated with, for example, hydroxypropylmethyl cellulose in various proportions to provide the desired release properties, other polymer matrices, liposomes and/or microspheres to provide slow or controlled release of the active ingredient therein. They may be sterilized, for example, by filtration through a bacteria-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions that can be dissolved in sterile water or some other injectable sterile vehicle immediately prior to use. These compositions may also optionally contain opacifying agents and may be of a composition that it releases the active ingredient only, or preferentially, in a certain portion of the gastrointestinal tract, optionally in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. The active ingredient may also be in microencapsulated form, if appropriate with the use of one or more of the above-mentioned excipients.
Liquid dosage forms of the compounds of the invention for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredients, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1, 3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof.
In addition to inert diluents, the oral compositions can also include adjuvants (adjuvants) such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming and preservative agents.
Suspensions, in addition to the active compounds, may contain co-excipients, for example ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.
Formulations of the pharmaceutical compositions of the present invention for rectal or vaginal administration may be presented as a suppository, which may be prepared by mixing one or more compounds of the present invention with one or more suitable non-irritating excipients or carriers comprising, for example, cocoa butter, polyethylene glycol, a suppository wax or salicylate, and which is solid at room temperature but liquid at body temperature and will therefore melt in the rectum or vaginal cavity and release the active compound.
Formulations of the invention suitable for vaginal administration also include pessaries, tampons, creams, gels, pastes, foams or spray formulations containing such carriers as are known in the art to be suitable.
Dosage forms for topical or transdermal administration of the compounds of the invention include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. The active ingredient may be mixed under sterile conditions with a pharmaceutically acceptable carrier and any preservatives, buffers, or propellants which may be required.
Ointments, pastes, creams and gels may contain, in addition to an active compound of the invention, excipients, such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof.
Powders and sprays can contain, in addition to a compound of the invention, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder or mixtures of these substances. Sprays can also contain conventional propellants such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.
Transdermal patches have the additional advantage of providing controlled delivery of the compounds of the present invention to the body. Such dosage forms may be prepared by dissolving or dispersing the compound in a suitable vehicle. Absorption enhancers may also be used to increase the flux of compounds through the skin. The rate of such flow can be controlled by providing a rate controlling membrane or dispersing the active compound in a polymer matrix or gel.
Also included within the scope of the present invention are ophthalmic formulations, ophthalmic ointments, powders, solutions, and the like.
Pharmaceutical compositions of the invention suitable for parenteral administration comprise one or more compounds of the invention and one or more pharmaceutically acceptable sterile isotonic aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions immediately prior to use, which may contain antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the recipient or suspending or thickening agents.
Examples of suitable aqueous and nonaqueous carriers that can be used in the pharmaceutical compositions of the invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils such as olive oil, and injectable organic esters such as ethyl oleate. Suitable fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.
These compositions may also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. Prevention of the action of microorganisms can be ensured by including various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, such as sugars, sodium chloride, and the like in the composition. In addition, prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin.
In some cases, in order to prolong the effect of the drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be achieved by using a liquid suspension of crystalline or amorphous material which is poorly water soluble. Thus, the rate of absorption of the drug will depend on its rate of dissolution, which in turn may depend on crystal size and crystal form. Alternatively, prolonged absorption of a parenterally administered drug form is achieved by dissolving or suspending the drug in an oily matrix.
Injectable depot forms are prepared by forming microencapsule matrices of the subject compounds in biodegradable polymers such as polylactide-polyglycolide. Depending on the ratio of drug to polymer and the nature of the particular compound used, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly (orthoesters) and poly (anhydrides). Injectable depot formulations can also be prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.
The formulations of the present invention may be administered orally, parenterally, topically or rectally. They are of course administered in a form suitable for the respective route of administration. For example, they are administered in the form of tablets or capsules, by injection, inhalation, ophthalmic lotion, ointment, suppository and the like, by injection, infusion or inhalation; topically applied by lotion or ointment; administered rectally by means of suppositories. Oral and/or intravenous administration is preferred.
The phrase "parenteral administration" as used herein means modes of administration other than enteral and topical administration, typically by injection, including, without limitation, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal and intrasternal injection and infusion.
The terms "systemic administration" and "peripheral administration" as used herein mean administration of a compound, drug or other material other than directly into the central nervous system, such that it enters the patient's system and is thus subject to metabolism and other similar processes, e.g., subcutaneous administration.
These compounds may be administered to humans and other animals for treatment by any suitable route of administration, including oral, nasal (e.g., in spray form), rectal, intravaginal, parenteral, intracisternal, and topical (in powder, ointment, or drop form) administration, including buccal and sublingual administration.
Regardless of the route of administration chosen, the compounds of the invention and/or the pharmaceutical compositions of the invention, which may be used in a suitable hydrated form, are formulated into pharmaceutically acceptable dosage forms using conventional methods known to those skilled in the art.
The actual dosage level of the active ingredient in the pharmaceutical compositions of the invention can be varied to obtain an amount of the active ingredient which is effective to achieve the desired therapeutic response for a particular patient, composition and mode of administration, and which is non-toxic to the patient.
The selected dosage level will depend upon a variety of factors including the activity of the particular compound of the invention or ester, salt or amide thereof employed, the route of administration, the time of administration, the rate of excretion of the particular compound employed, the duration of the treatment, other drugs, compounds and/or materials used in combination with the particular compound employed, the age, sex, body weight, condition, general health and prior medical history of the patient being treated, and like factors well known in the medical arts.
A physician or veterinarian of ordinary skill in the art can readily determine and prescribe the effective amount of the pharmaceutical composition required. For example, a physician or veterinarian can start a dose of a compound of the invention employed in a pharmaceutical composition at a level lower than that required to achieve the desired therapeutic effect and gradually increase its dose until the desired effect is achieved.
In general, a suitable daily dose of a compound of the invention will be that amount of the compound which is the lowest dose effective to produce a therapeutic effect. Such effective dosages will generally depend on the factors described above. In general, when used for the analgesic effects indicated, the compounds of the invention are administered to a patient in intravenous and subcutaneous doses of from about 0.0001 to about 100mg/kg body weight/day, more preferably from about 0.01 to about 50 mg/kg/day, and even more preferably from about 1.0 to about 100 mg/kg/day. An effective amount is an amount that treats a condition associated with a protein kinase.
If desired, an effective daily dose of the active compound may be administered at suitable intervals throughout the day in two, three, four, five, six or more sub-doses administered separately, optionally in unit dosage forms.
For an individual of about 50-70kg, the pharmaceutical composition or combination of the invention may be in a unit dose of about 1-1000mg of the active ingredient, or about 1-500mg or about 1-250mg or about 1-150mg or about 0.5-100mg or about 1-50mg of the active ingredient. The therapeutically effective dose of the compound, pharmaceutical composition or combination thereof will depend on the species, weight, age and condition of the individual, the disorder or disease being treated or its severity. A physician, clinician or veterinarian of ordinary skill can readily determine the effective amount of each active ingredient which is required to prevent, treat or inhibit the progression of the disorder or disease.
The above dosage properties are illustrated for mammals, such as mice, rats, dogs, monkeys or their related organs, tissues or preparations, which are advantageous for use in vitro and in vivo assays. The compounds of the invention can be applied in vitro in the form of solutions, for example aqueous solutions, and in vivo enterally, parenterally, advantageously intravenously, for example as suspensions or aqueous solutions. The in vitro dosage may range between about 10-3 molar and 10-9 molar. The therapeutically effective amount in vivo can range from about 0.1 to 500mg/kg or between about 1 to 100mg/kg, depending on the route of administration.
The term "individual" as used herein means an animal. Typically, the animal is a mammal. A subject also means, for example, a primate (e.g., human, male or female), cow, sheep, goat, horse, dog, cat, rabbit, rat, mouse, fish, bird, and the like. In certain embodiments, the subject is a primate. In other embodiments, the individual is a human.
Although the compounds of the present invention may be administered alone, it is preferred to administer the compounds in the form of a pharmaceutical composition.

In vitro antitumor Activity assay of Compounds of the invention
The in vitro enzymology level detection method adopts PD-1/PD-L1 binding assay kit of Cisbio company
1. The experimental principle is as follows:
PD-1 protein has HIS label, PD-L1 ligand of PD-1 has hFc label, and Eu-labeled anti-hFc antibody and XL 665-labeled anti-HIS antibody are respectively combined with two label proteins. After laser excitation, energy can be transferred from the donor Eu to the acceptor XL665, so that XL665 emits light. After the inhibitor is added, the binding of PD-1 and ligand PD-L1 is blocked, so that Eu and XL665 are far away, energy cannot be transferred, and XL665 does not emit light.
2. The experimental method comprises the following steps:
a PD1/PD-L1 binding assay was performed using the HTRF assay kit from Cisbio Bioassays (catalog number 64ICP01PEG) with specific operating methods referring to kit instructions briefly described as follows, using a 384 well white microplate, the compounds were dissolved in DMSO solution at a concentration of 10 mM., the compound stock solution was diluted 40-fold with diluent first, then diluted 5-fold with a kit dilution buffer containing 2.5% DMSO. 4ul of the diluent or the target compound diluted with the diluent was added to each well, the final DMSO concentration was 0.5%. PD1 and PD-L1 solutions were added at 3ul per well, respectively, after preincubation of the compounds with PD1 and PD-L1 for 10 minutes, 10ul of detection antibody prepared according to the product instructions was added to each well after overnight incubation of the plate at room temperature, data were obtained by reading the plate in a PHERAStar FS microplate reader (BMG, Germany). HTRF signal calculation was 10000 (Prisph) and the synthetic reaction curve was obtained by fitting the ramp curve (Prispague curve) with variable reaction curve of each reaction curve obtained by calculating the ramp curve of the ramp 3-7-PCR curve (Prispagy curve) 50The value is obtained.
