Description

[Technical Field]

[0001] The present disclosure relates to small molecule modulators that promote the binding of butyrophilin 3A1 (BTN3A1) and butyrophilin 2A1 (BTN2A1) in vivo, thereby exerting their respective biological functions, including applications in the treatment of tumors and infectious diseases. [Background technology]

[0002] Butyrophilins (BTNs) are a class of transmembrane proteins that generally exert their specific biological functions by forming heteropolymers. Both butyrophilin 3A1 (BTN3A1) and butyrophilin 2A1 (BTN2A1) proteins contain two extracellular domains (IgV and IgC), a transmembrane domain (TM), a proximal coiled-coil domain (JM), and an intracellular B30.2 domain. The intracellular B30.2 domain of BTN2A1 shares up to 50% homology with that of BTN3A1. However, BTN2A1 lacks key basic amino acids in its ligand-binding pocket, and target cells are only recognized by immune cells, such as αβ and γδ T cells, when the B30.2 domain of BTN3A1 binds to the B30.2 domain of BTN2A1.

[0003] For example, γ9Vδ2 T cells are a common subtype of γδ T cells, an important type of immune cell, and play a key role in linking innate and adaptive immunity. After activation, Vγ9Vδ2 T cells can produce killing effects against tumor cells and multiple pathogens. Vγ9Vδ2 T cells play important roles in anti-infective and anti-tumor applications. Although BTN3A1 plays a key role in the identification and activation of Vγ9Vδ2 T cells, small molecules that bind only to BTN3A1 have no biological function. Only when a small molecule can promote the binding of the intracellular segment of BTN3A1 to BTN2A1 can it activate Vγ9Vδ2 T cells.

[0004] HMBPP is a naturally occurring small molecule produced within cells after infection with an infectious agent. Its activity in activating BTN3A1 / BTN2A1 is thousands of times greater than that of endogenous molecules such as IPP and DMAPP. Under physiological conditions, HMBPP carries two negative charges, making it difficult for it to enter cells by itself. Its activity is weak after short incubation periods (2-hour pulse stimulation). At the same time, HMBPP has poor plasma stability and poor druggability. Although the activity of C-HMBPP has shown some improvement compared to HMBPP, its short-term stimulatory activity remains weak.

[0005] Both patents WO2020008189 and WO2019182904 provide several new molecules. Other than in vitro activity data, the in vivo activity and subsequent clinical information of these molecules have not yet been disclosed.

[0006] This disclosure describes a small molecule compound that can effectively promote the binding of the intracellular B30.2 domain of BTN3A1-BTN2A1 and its use in the treatment of diseases. This molecule has high activity and good druggability. Summary of the Invention [Problem to be solved by the invention]

[0007] The present disclosure demonstrates, using size-exclusion chromatography-multi-angle light scattering (SEC-MALS) and sedimentation velocity ultracentrifugation (SV-AUC) studies, that the BTN3A1 B30.2 domain and the BTN2A1 B30.2 domain do not associate in the absence of a modulator. Furthermore, even if a small molecule is added, if the small molecule can only bind to the BTN3A1 B30.2 domain, it cannot activate Vy9V52 T cells; only when the B30.2 domains of both proteins are attached to each other by a small molecule (such as one disclosed in the present application) can Vy9V52 T cell activation be promoted.

[0008] The compounds provided by the present disclosure have the ability to promote 3A1-2A1 binding and activate Vγ9Vδ2 T cells. Furthermore, some compounds provided by the present disclosure have good stability, low clearance rates, and low plasma protein binding rates. This is advantageous for generating more free active drug in the blood. Furthermore, some compounds provided by the present disclosure have comprehensive properties favorable for druggability, such as longer human liver microsome stability and lower plasma protein binding rates, in addition to good cytocidal activity.

[0056] [Figure 1] This shows the binding mode of a small molecule compound (compound 7) with BTN3A1 in vivo, demonstrating that the R1 group of the general formula molecule is substantially exposed to the solvent and can be derivatized in various ways without affecting the binding of the small molecule compound with BTN3A1.

[0057] [Figure 2] The simultaneous binding mode of a small molecule compound (compound 7) with BTN3A1 and BTN2A1 in vivo indicates that the R1 structure of the general formula molecule is constrained by a specific cavity, and only R1 with a specific spatial size can simultaneously bind to BTN3A1 and BTN2A1 and exert the corresponding biological effects.

[0058] Figures 1 and 2 show that the requirements for small molecule ligands designed based on the BTN3A1 model (Figure 1) are quite different from those for small molecule ligands designed based on the BTNA1-BTN2A1 model (Figure 2). In the model shown in Figure 2, small molecules can only exert their biological functions if they simultaneously bind to the cavity formed by BTN3A1 and BTN2A1. DETAILED DESCRIPTION OF THE INVENTION

[0075] "C 0-6 An "alkylene group" is a group consisting of a chemical bond and a "C" as defined above. 1-6 The term "alkylene group" refers to an "alkylene group."

[0076] In a compound, a chemical bond " [ka] " is used, it means that the cis and trans isomers of the compound coexist in any ratio, i.e., it may be the cis isomer, the trans isomer, or a mixture thereof.

[0077] Alkyl, alkenyl, alkynyl, aryl, heteroaryl, and the like, as defined herein, are optionally substituted groups, whether or not previously described as "optionally substituted." In general, the term "substituted," whether or not previously described as "optionally," refers to the replacement of at least one hydrogen atom present in a group (e.g., on a carbon atom or nitrogen atom) with a permissible substituent, e.g., a substituent that, upon substitution, results in a stable compound, e.g., a compound that does not spontaneously undergo transformation (e.g., by rearrangement, cyclization, elimination, or other reaction). Unless otherwise specified, a "substituted" group has a substituent at one or more substitutable positions of the group, and when multiple positions are substituted in any given structure, the substituents at each position are the same or different. The term "substituted" includes substitution with all permissible substituents of organic compounds (any substituents described herein that result in the formation of a stable compound).

[0318] The compounds of the present disclosure may contain one or more asymmetric centers and therefore may exist in various stereoisomeric forms, such as enantiomers and / or diastereomers. For example, the compounds of the present disclosure may be in the form of individual enantiomers, diastereomers, or geometric isomers (e.g., cis and trans isomers), or in the form of mixtures of stereoisomers, such as racemic mixtures and mixtures enriched in one or more stereoisomers. Individual isomers can be separated from mixtures by methods known to those skilled in the art, such as chiral high-pressure liquid chromatography (HPLC) and the formation and crystallization of chiral salts. Alternatively, alternative isomers can be prepared by asymmetric synthesis.

[0319] The present disclosure also includes all suitable isotopic derivatives of the compounds of the present disclosure.The isotopic derivatives of the compounds of the present disclosure are defined as derivatives in which at least one atom is replaced with an atom that has the same atomic number but has an atomic mass that is different from the atomic mass that is usually found in nature.The examples of isotopes that can be incorporated into the compounds of the present disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, fluorine and chlorine, for example, 2 H, 3 H, 13 C. 14 C. 15 N, 17 O. 18 O. 18 F, 31 P, 32 P, 35 S and 36 Some isotopic derivatives of the compounds of the present disclosure include, for example, 3 H or 14 Those incorporating radioactive isotopes such as C are useful for drug and / or substrate tissue distribution studies. Tritiated (i.e. 3 H) and carbon-14 (i.e. 14 C) isotopes are a further option because they are easy to prepare and detectable. In addition, isotopes (e.g., deuterium, i.e. 2H) may be an option in some circumstances, as it may offer certain therapeutic advantages due to greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements. Isotopic derivatives of the compounds of the present disclosure can generally be prepared by conventional procedures, such as the exemplary methods or preparations described in the Examples below, using appropriate isotopic derivatives of appropriate reagents.

[0320] The compounds of the present disclosure, or their pharmaceutically acceptable salts, may be amorphous or crystalline. Furthermore, the compounds of the present disclosure may exist in one or more crystalline forms. Accordingly, the present disclosure includes within its scope all amorphous or crystalline forms of the compounds of the present disclosure. The term "polymorph" refers to a crystalline form of a compound (or its salts, hydrates, or solvates) in a specific crystal packing arrangement. All polymorphs have the same elemental composition. Different crystalline forms generally have different X-ray diffraction patterns, infrared spectra, melting points, densities, hardness, crystal shapes, optical properties, electrical properties, stability, and solubility. Factors such as the recrystallization solvent, crystallization rate, and storage temperature may result in one crystalline form predominating. Various polymorphs of a compound can be prepared by crystallization under different conditions.

[0321] Those skilled in the art will appreciate that many organic compounds can form complexes with solvents in which they react or from which they precipitate or crystallize. These complexes are known as "solvates." When the solvent is water, the complex is known as a "hydrate." The present disclosure encompasses all solvates of the compounds of the present disclosure.

[0330] Experimental procedures

[0331] Step 1: Diethyl but-3-en-1-ylphosphonate (Int-A1) [ka]

[0332] Diethyl phosphite (15 g, 108.62 mmol, 14.02 mL, 1 equiv.) was added dropwise to a solution of sodium hydride (5.21 g, 130.34 mmol, 60% w / w, 1.2 equiv.) in anhydrous tetrahydrofuran (300 mL) under nitrogen protection at 0° C., and the mixture was stirred at 20° C. for 1 hour. Next, 4-bromo-1-butene (17.60 g, 130.34 mmol, 13.23 mL, 1.2 equiv.) was added, and the mixture was stirred at 60° C. for 5 hours. After the reaction was completed, the mixture was cooled to room temperature and quenched by adding saturated ammonium chloride solution (300 mL). The mixture was extracted with ethyl acetate (300 mL × 3). The combined organic layers were dried over anhydrous sodium sulfate and concentrated under reduced pressure to give a residue. The residue was purified by column chromatography on silica gel eluting with 0-55% petroleum ether / ethyl acetate to give diethyl 3-butenylphosphonate (18.4 g, 95.74 mmol, 88.14% yield) as a colorless oil.

[0333] 1 H NMR (400 MHz, CDCl3) δ = 5.82 - 5.75 (m, 1H), 5.02 - 4.93 (m, 2H), 4.06 - 4.00(m, 4H), 2.28 - 2.21 (m, 2H), 1.80 - 1.71 (m, 2H), 1.27 (t, J = 7.2 Hz, 6H);

[0334] 31 P NMR (162 MHz, CDCl3) δ = 31.48.

[0335] Step 2: Bis(trimethylsilyl)but-3-en-1-ylphosphonate (Int-A2) [ka]

[0336] To a solution of diethyl but-3-en-1-ylphosphonate (18.4 g, 95.74 mmol, 1 equiv.) in dichloromethane (600 mL) was added trimethylsilyl bromide (146.48 g, 957.4 mmol, 10 equiv.) dropwise under nitrogen protection at 20° C., and the mixture was stirred for 4 hours at 20° C. After the reaction was completed, the mixture was concentrated under reduced pressure to remove the solvent to give bis(trimethylsilyl)but-3-en-1-ylphosphonate (25 g, 93% yield) as a yellow oil, which was used directly in the next step without further treatment.

[0337] 1 H NMR (400 MHz, CDCl3) δ = 5.82 - 5.75 (m, 1H), 5.04 - 4.95 (m, 2H), 2.30 - 2.25 (m, 2H), 1.86 - 1.80 (m, 2H), 0.27 (s, 18H);

Then, to the mixture was added triethylamine (701.87 mg, 6.94 mmol, 1 equiv.) dropwise under nitrogen protection at −78° C. The mixture was stirred at 25° C. for 16 hours. After the reaction was completed, the reaction mixture was cooled to room temperature and concentrated under reduced pressure to remove the solvent to give 1-naphthyl dichlorophosphate (1.2 g, 66.7% yield) as a colorless oil, which was used directly in the next step without further treatment.
