[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 63 / 478,449, filed January 4, 2023, the entire contents of which are incorporated herein by reference.
[0002] The present disclosure provides compounds and salts thereof that bind to cereblon and thereby modulate its activity. In some embodiments, certain compounds described herein bind to cereblon, thereby reducing cellular IKAROS family zinc finger (IKZF) protein levels. In some embodiments, certain compounds described herein bind to cereblon but do not thereby reduce cellular IKZF protein levels. In some embodiments, compounds disclosed herein bind to cereblon, thereby initiating degradation of IKZF proteins (e.g., IKZF2). Also disclosed are pharmaceutical compositions comprising the above-described compounds or salts thereof (e.g., pharmaceutically acceptable salts thereof), as well as methods of using such compounds and / or salts thereof to treat various diseases or disorders mediated by IKZF2. [Background technology]
[0003] IKAROS family zinc finger 2 (IKZF2) (also known as Helios) is one of five members of the Ikaros transcription factor family found in mammals. IKZF2 is a key regulator of T cell activity and function. Genetic deletion of Helios enhanced antitumor immune responses (Kim et al., Science 350:334-339 (2015)). In particular, Helios is highly expressed in regulatory T cells (Tregs) (Elkord et al., Expert Opin. Biol. Ther. 12:1423-1425 (2012)), a subpopulation of T cells that limit the activity of effector T cells. Selective deletion of Helios in regulatory T cells resulted in both loss of suppressive activity and acquisition of effector T cell function (Najagawa et al., Proc. Natl. Acad. Sci. USA 113:6248-6253 (2016); Yates et al., Proc. Natl. Acad. Sci. USA 115:2162-2167 (2018)). Thus, Helios is a key factor limiting T cell effector function in Tregs.
[0004] Helios expression has also been reported to be upregulated in "exhausted" T cells in the context of two types of chronic viral infection (Crawford et al., Immunity 40:289-302 (2014), Doering et al., Immunity 371130-1144 (2012); Scott-Browne et al., Immunity 45:1327-1340 (2016)) and tumors (Martinez et al., Immunity 42:265-278 (2015); Mognol et al., Proc. Natl. Acad. Sci. USA 114:E2776-E2785 (2017); Pereira et al., J. Leukoc. Biol. 102:601-615 (2017); Singer et al., Cell 166:1500-1511 (2016); Schietinger et al., Immunity 45:389-401 (2016)), and dysfunctional chimeric antigen receptor (CAR) T cells (Long et al., Nat. Med. 21:581-590 (2015)). Overexpression or aberrant expression of Helios and various splice isoforms has been reported in several hematological malignancies, including T-cell leukemia and lymphoma (Nakase et al., Exp. Hematol. 30:313-317 (2002); Tabayashi et al., Cancer Sci. 98:182-188 (2007); Asanuma et al., Cancer Sci. 104:1097-1106 (2013)). Furthermore, knockdown of Helios in a mixed lineage leukemia (MLL)-induced myeloid leukemia model effectively suppressed proliferation and increased cell death (Park et al., J. Clin. Invest. 125:1286-1298 (2015); Park et al., Cell Stem Cell 24:153-165 (2019)).
[0005] Anti-CTLA4 antibodies are currently used clinically to target Tregs in tumors. However, targeting CTLA4 often leads to systemic activation of T effector cells, resulting in excessive toxicity and limiting the effectiveness of the treatment. Grade 3 or higher adverse events have been reported in up to 75% of patients treated with anti-PD1 and anti-CTLA4 combination therapy (National Cancer Institute, Division of Cancer Treatment and Diagnosis, Common Terminology for Adverse Events (CTCAE), https: / / ctep.cancer.gov / protocolDevelopment / electronic_applications / ctc.htm).
[0006] There is a need for therapies that can target Tregs in tumors without causing systemic activation of T effector cells. Thus, IKZF2-specific modulators or degraders may focus enhanced immune responses in tumor or peritumoral regions, potentially providing better-tolerated and less toxic therapies for the treatment of IKZF2-mediated diseases.

DETAILED DESCRIPTION OF THE INVENTION
[0020] The present disclosure provides compounds, pharmaceutical compositions containing such compounds, and methods of using such compounds and compositions to treat diseases, disorders, or conditions mediated, at least in part, by the IKZF2 transcription factor. However, prior to describing the disclosure in detail, the following terms are first defined. Unless defined, terms used herein have their generally accepted scientific meaning.
[0021] definition The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
[0022] A dash ("-") that is not between two letters or symbols is used to indicate a point of attachment for a substituent. For example, -C(O)NH2 is attached through the carbon atom. The use of dashes at the beginning or end of a chemical group is a matter of convenience, and a chemical group may be represented using one or more dashes without loss of ordinary meaning. A wavy or dashed line drawn across a line in a structure indicates a particular point of attachment of the group. Unless chemically or structurally required, no directionality or stereochemistry is indicated or implied by the order in which chemical groups are written or designated.
[0023] "C u-v " prefix indicates that the following group has u to v carbon atoms. For example, "C 1-6 "Alkyl" indicates that the alkyl group has from 1 to 6 carbon atoms.
[0024] The term "about," when used before a numerical designation including a range, such as temperature, time, amount, concentration, etc., indicates an approximation that may vary by (±) 10%, 5%, 1%, or any subrange or subvalue therebetween. In one embodiment, the term "about" used in reference to a dosage means that the dosage may vary by ±10%.
[0025] By "comprising" or "comprises," it is intended that the compositions and methods include the recited elements, but do not exclude other elements.
[0026] When used to define compositions and methods, "consisting essentially of" shall mean excluding other elements of any essential importance to the recited combination. Thus, a composition consisting essentially of elements as defined herein will not exclude other materials or steps that do not materially affect the basic and novel characteristic(s) of the claimed disclosure.

As used herein, heterocyclyl refers to a ring having 2 to 20 ring carbon atoms (i.e., C 2-20 heterocyclyl), 2 to 12 ring carbon atoms (i.e., C 2-12 heterocyclyl), 2 to 10 ring carbon atoms (i.e., C 2-10 heterocyclyl), 2 to 8 ring carbon atoms (i.e., C 2-8 heterocyclyl), 3 to 12 ring carbon atoms (i.e., C 3-12 heterocyclyl), 3 to 8 ring carbon atoms (i.e., C 3-8 heterocyclyl), or 3 to 6 ring carbon atoms (i.e., C 3-6Heterocyclyl) has 1 to 5 ring heteroatoms, 1 to 4 ring heteroatoms, 1 to 3 ring heteroatoms, 1 to 2 ring heteroatoms, or 1 ring heteroatom independently selected from nitrogen, sulfur, or oxygen. Examples of heterocyclyl groups include, for example, azetidinyl, azepinyl, benzodioxolyl, benzo[b][1,4]dioxepinyl, 1,4-benzodioxanyl, benzopyranyl, benzodioxinyl, benzopyranonyl, benzofuranonyl, dioxolanyl, dihydropyranyl, hydropyranyl, thienyl[1,3]dithianyl, decahydroisoquinolyl, furanonyl, imidazolinyl, imidazolidinyl, indolinyl, indolizinyl, isoindolinyl, isothiazolidinyl, isoxazolidinyl, morpholinyl, octahydroindoline, and the like.
[0033] The term "heterocyclyl" includes "spiroheterocyclyl" when there are two substitution positions on the same carbon atom. Examples of spiroheterocycles include bicyclic and tricyclic ring systems such as oxabicyclo[2.2.2]octanyl, 2-oxa-7-azaspiro[3.5]nonanyl, 2-oxa-6-azaspiro[3.4]octanyl, and 6-oxa-1-azaspiro[3.3]heptanyl. Examples of fused heterocyclyl rings include, but are not limited to, 1,2,3,4-tetrahydroisoquinolinyl, 4,5,6,7-tetrahydrothieno[2,3-c]pyridinyl, indolinyl, and isoindolinyl, and the heterocyclyl can be attached via either ring of the fused system. In some embodiments, heterocycloalkyls can be substituted with oxo group(s) on the heteroatom (e.g., S=O, S(=O)).

[0061] The terms "optional" or "optionally" mean that the subsequently described event or circumstance may or may not occur, and include cases where the event or circumstance occurs and cases where the event or circumstance does not occur. Also, the term "optionally substituted" refers to any one or more (e.g., 1 to 5 or 1 to 3) hydrogen atoms on a specified atom or group that may or may not be replaced with a non-hydrogen moiety.
[0062] As used herein, the term "substituted" means that in any of the above groups (i.e., alkyl, alkenyl, alkynyl, alkylene, alkoxy, haloalkyl, haloalkoxy, cycloalkyl, aryl, heterocyclyl, heteroaryl, and / or heteroalkyl), at least one (e.g., 1 to 5 or 1 to 3) hydrogen atom is replaced with a bond to a non-hydrogen atom, and the non-hydrogen atom can be, for example, an alkyl, alkenyl, alkynyl, alkoxy, alkylthio, acyl, amido, amino, amidino, aryl, aralkyl, or the like. , azide, carbamoyl, carboxyl, carboxyl ester, cyano, cycloalkyl, cycloalkylalkyl, guanidino, halo, haloalkyl, haloalkoxy, hydroxyalkyl, heteroalkyl, heteroaryl, heteroarylalkyl, heterocyclyl, heterocyclylalkyl, -NHNH2, =NNH2, imino, imido, hydroxy, oxo, oxime, nitro, sulfonyl, sulfinyl, alkylsulfonyl, alkylsulfinyl, thiocyanate, -S(O)OH, -S(O)2OH, sulfonamide, thiol, thioxo, N-oxide, or -Si(R y)3, each R y is independently hydrogen, alkyl, alkenyl, alkynyl, heteroalkyl, cycloalkyl, aryl, heteroaryl, or heterocyclyl.

[0064] Polymers or similar undefined structures obtained by defining a substituent with an infinite number of additional substituents (e.g., a substituted aryl with a substituted alkyl, which is itself substituted with a substituted aryl group, which is further substituted with a substituted heteroalkyl group, etc.) are not intended to be included herein. Unless otherwise specified, the maximum number of consecutive substitutions in the compounds described herein is three. For example, consecutive substitution of a substituted aryl group with two other substituted aryl groups is limited to [(substituted aryl)substituted aryl]substituted aryl. Similarly, the above definition is not intended to include impermissible substitution patterns (e.g., a methyl substituted with five fluorine atoms or a heteroaryl group with two adjacent oxygen ring atoms). Such impermissible substitution patterns are well known to those skilled in the art. When used to modify a chemical group, the term "substituted" can describe other chemical groups defined herein.
[0065] In certain embodiments, the phrase "one or more," as used herein, refers to 1 to 5. In certain embodiments, the phrase "one or more," as used herein, refers to 1 to 3.
[0066] Any compound or structure provided herein is also intended to represent unlabeled and isotopically labeled forms of the compound. These forms of compounds are also referred to as "isotopically enriched analogs." Isotopically labeled compounds have the structure shown herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into the disclosed compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, chlorine, and iodine, for example, 2 H, 3 H, 11 C. 13 C. 14 C. 13 N, 15 N, 15 O. 17 O. 18 O. 31 P,32 P, 35 S, 18 F, 36 Cl, 123 I, and 125 I. Various isotopically labeled compounds of the present disclosure include, for example, 3 H, and 14 and those into which a radioactive isotope such as C is incorporated. Such isotopically labeled compounds may be useful in detection or imaging techniques including metabolism studies, reaction kinetic studies, drug or substrate tissue distribution assays, for example, positron emission tomography (PET) or single photon emission computed tomography (SPECT), or in radiotherapy of patients.
[0067] The term "isotopically enriched analog" includes "deuterated analogs" of the compounds described herein, in which one or more hydrogens (e.g., hydrogens on carbon atoms) are replaced with deuterium. Such compounds exhibit increased resistance to metabolism and are therefore useful for increasing the half-life of any compound when administered to mammals, particularly humans. See, for example, Foster, "Deuterium Isotope Effects in Studies of Drug Metabolism," Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compounds are synthesized by means well known in the art, for example, by using starting materials in which one or more hydrogens have been replaced with deuterium.
[0068] Deuterium-labeled or substituted therapeutic compounds of the present disclosure may have improved DMPK (drug metabolism and pharmacokinetic) properties related to absorption, distribution, metabolism, and excretion (ADME). Substitution with heavier isotopes, such as deuterium, may confer certain therapeutic advantages resulting from greater metabolic stability, e.g., increased in vivo half-life, reduced dosage requirements, and / or improved therapeutic index. 18 F, 3 H, or 11C-labeled compounds can be useful for PET, SPECT, or other imaging studies. The isotopically labeled compounds of the present disclosure and their prodrugs can generally be prepared by substituting readily available isotopically labeled reagents with non-isotopically labeled reagents, and carrying out the procedures disclosed in the schemes or in the examples and preparations described below. It is understood that deuterium in this context is considered a substituent in the compounds provided in the present disclosure.
[0069] The concentration of such heavier isotopes, specifically deuterium, can be defined by the isotopic enrichment factor. In the compounds of the present disclosure, any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise specified, when a position is specifically designated as "H" or "hydrogen," that position is understood to have hydrogen at its natural abundance isotopic composition. Thus, in the compounds of the present disclosure, any atom specifically designated as deuterium (D) is meant to represent deuterium.
[0070] In many cases, the compounds of the present disclosure are capable of forming acid and / or base salts by virtue of the presence of amino and / or carboxyl groups or groups similar thereto.
[0071] Pharmaceutically acceptable salts, isotopically enriched analogs, deuterated analogs, stereoisomers, mixtures of stereoisomers, and prodrugs of the compounds described herein are also provided. "Pharmaceutically acceptable" or "physiologically acceptable" refers to compounds, salts, compositions, dosage forms, and other materials useful in the preparation of pharmaceutical compositions suitable for veterinary or human pharmaceutical use.
[0072] The term "solvate" can include, but is not limited to, solvates that retain one or more activity and / or properties of a compound and are not undesirable. Examples of solvates include, but are not limited to, a compound in combination with water, isopropanol, ethanol, methanol, DMSO, ethyl acetate, acetic acid, ethanolamine, or a combination thereof.
[0073] The term "pharmaceutically acceptable salt" of a given compound refers to a salt that retains the biological effectiveness and properties of the given compound and is not biologically or otherwise undesirable. "Pharmaceutically acceptable salts" or "physiologically acceptable salts" include, for example, salts with inorganic acids and salts with organic acids. Furthermore, if a compound described herein is obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid salt. Conversely, if the product is a free base, an addition salt, particularly a pharmaceutically acceptable addition salt, can be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid, according to conventional procedures for preparing acid addition salts from base compounds. Those skilled in the art will recognize various synthetic methods that can be used to prepare non-toxic pharmaceutically acceptable addition salts. Pharmaceutically acceptable acid addition salts can be prepared from inorganic or organic acids. Salts derived from inorganic acids include, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like. Salts derived from organic acids include, for example, acetic acid, propionic acid, gluconic acid, glycolic acid, pyruvic acid, oxalic acid, malic acid, malonic acid, succinic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluene-sulfonic acid, salicylic acid, and the like. Similarly, pharmaceutically acceptable base addition salts can be prepared from inorganic or organic bases. Salts derived from inorganic bases include, by way of example only, sodium, potassium, lithium, ammonium, calcium, and magnesium salts.Salts derived from organic bases include alkylamines (i.e., NH2(alkyl)), dialkylamines (i.e., HN(alkyl)2), trialkylamines (i.e., N(alkyl)3), substituted alkylamines (i.e., NH2(substituted alkyl)), di(substituted alkyl)amines (i.e., HN(substituted alkyl)2), tri(substituted alkyl)amines (i.e., N(substituted alkyl)3), alkenylamines (i.e., NH2(alkenyl)), dialkenylamines (i.e., HN(alkenyl)2), trialkenylamines (i.e., N(alkenyl)3), substituted alkylamines Suitable amines include, but are not limited to, salts of primary, secondary, and tertiary amines such as alkenylamines (i.e., NH(substituted alkenyl)), di(substituted alkenyl)amines (i.e., HN(substituted alkenyl)), tri(substituted alkenyl)amines (i.e., N(substituted alkenyl)), mono-, di-, or tri-cycloalkylamines (i.e., NH(cycloalkyl), HN(cycloalkyl), N(cycloalkyl)), mono-, di-, or tri-arylamines (i.e., NH(aryl), HN(aryl), N(aryl)), or mixed amines. Specific examples of suitable amines include, by way of example only, isopropylamine, trimethylamine, diethylamine, tri(isopropyl)amine, tri(n-propyl)amine, ethanolamine, 2-dimethylaminoethanol, piperazine, piperidine, morpholine, N-ethylpiperidine, and the like.
[0074] Some compounds exist as tautomers. Tautomers are in equilibrium with each other. For example, an amide-containing compound may exist in equilibrium with an imidic acid tautomer. Regardless of which tautomer is shown and the nature of the equilibrium between the tautomers, one skilled in the art will understand that the compound includes both the amide and imidic acid tautomers. Thus, an amide-containing compound is understood to include its imidic acid tautomer. Similarly, an imidic acid-containing compound is understood to include its amide tautomer.
[0075] The compounds, or pharmaceutically acceptable salts thereof, may contain asymmetric centers and thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that can be defined in terms of absolute stereochemistry as (R)- or (S)- (or, in the case of amino acids, (D)- or (L)-). The present disclosure is intended to encompass all such possible isomers, as well as their racemic and optically pure forms. Optically active (+)- and (−), (R)- and (S)-, or (D)- and (L)-isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques such as chromatography and / or fractional crystallization. Prior techniques for preparing / isolating individual enantiomers include chiral synthesis from suitable optically pure precursors, or resolution of the racemate (or racemate of a salt or derivative) using, for example, chiral high-pressure liquid chromatography (HPLC). When compounds described herein contain olefinic double bonds or other centers of geometric asymmetry, unless otherwise specified, the compounds are intended to include both E and Z geometric isomers.
[0076] "Stereoisomer" refers to a compound consisting of the same atoms connected by the same bonds, but having different three-dimensional structures that are not interchangeable. The present disclosure contemplates various stereoisomers, or mixtures thereof, and includes "enantiomers," which refers to two stereoisomers whose molecules are non-superimposable mirror images of one another.
[0077] "Diastereomers" are stereoisomers that have at least two asymmetric atoms, but which are not mirror-images of each other.
[0078] Relative centers of compounds depicted herein are depicted using a "bold bond" style (bold or parallel lines) and absolute stereochemistry is represented using a wedge bond (bold or parallel lines).
[0079] "Prodrug" refers to any compound that, upon administration to a mammalian subject, releases an active parent drug in vivo according to the structure described herein. Prodrugs of the compounds described herein are prepared by modifying functional groups present in the compounds described herein so that the modifications can be cleaved in vivo to release the parent compound. Prodrugs can be prepared by modifying functional groups present in the compounds described herein in such a way that the modifications are cleaved to the parent compound, either by routine manipulation or in vivo. Prodrugs include compounds described herein in which a hydroxy, amino, carboxyl, or sulfhydryl group in the compounds described herein is bonded to any group that can be cleaved in vivo to regenerate the free hydroxy, amino, or sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to, esters (e.g., acetate, formate, and benzoate derivatives), amides, guanidines, carbamates (e.g., N,N-dimethylaminocarbonyl), and the like, of the hydroxy functional groups of the compounds described herein. The preparation, selection, and use of prodrugs are described in T. Higuchi and V. Stella, "Pro-drugs as Novel Delivery Systems," Vol. 14 of the ACS Symposium Series; "Design of Prodrugs," ed. H. Bundgaard, Elsevier, 1985; and Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, each of which is incorporated herein by reference in its entirety.

Complete medium (2 mL) was added to resuspend the cells to form a single cell suspension. The cells were centrifuged at 320 x g for 5 minutes at room temperature, the supernatant was removed, and the cell pellet was resuspended in Opti-MEM (3 mL; the washing step was repeated twice). After a final resuspension in 5 mL of Opti-MEM, the cells were counted and resuspended at 200,000 cells / mL in Opti-MEM.
[0228] Cereblon target engagement was monitored by bioluminescence resonance energy transfer (BRET) in transfected HEK-293T cells using the NanoBRETTE Intracellular E3 Ligase Assay (Promega). Briefly, transfected HEK-293T cells (38 μL / well) were seeded into a 384-well plate (white opaque plate, Corning 3574, low-binding surface). 2 μL of 10 μM CRBN tracer (diluted 1:5 in tracer dilution buffer) was added to each well. The plate was centrifuged at 320 x g for 1 minute at room temperature. Test compounds were added in an 11-step dilution series (typically 10 μM to 100 pM) using a TECAND 300e digital dispenser. The plate was shaken for 2 minutes on a microplate shaker to mix the compounds. The plate was centrifuged at 320 x g for 1 minute at room temperature and then incubated at 37 °C for 2 hours.
[0229] After incubation, the plate was allowed to cool at room temperature for 15 minutes. 20 μL of 3X Complete NanoBRET™ Nano-Glo® substrate and inhibitor solution (Promega, substrate 1:166, extracellular NanoLuc® inhibitor diluted 1:500 in Opti-MEM) was added to each well. The plate was covered with aluminum foil and incubated at room temperature with shaking for 3 minutes. The plate was measured at 450 nm (donor emission) and 610 nm (acceptor emission) on a CLARIOstar microplate reader (BMG LabTech). IC 50 Values were determined by regression analysis using Graph Pad Prism to best fit a four-parameter logistic curve.
[0230] IKZF2 degradation assay Generation of stable cell lines A polycistronic plasmid was constructed to express fluorescent reporter fusion proteins of the human transcription factors IKZF1 (Ikaros), IKZF2 (Helios), and IKZF3 (Aiolos) in mammalian cells. Each protein sequence contains three repeats of the GGGGS linker at the C-terminus, followed by mNeonGreen, P2A, and mScarlet. The DNA sequences of the open reading frames are as follows:
[0231] IKZF1-mNeonGreen-P2A-mScarlet coding sequence (SEQ ID NO. 1):
[0232] Coding sequence of IKZF2-mNeonGreen-P2A-mScarlet (SEQ ID NO. 2):
[0233] Coding sequence of IKZF3-mNeonGreen-P2A-mScarlet (SEQ ID NO. 3):
[0234] IKZF1, IKZF2, and IKZF3 constructs were cloned into the UCOE-hygromycin expression vector (Millipore Sigma). The reporter constructs were transfected into adherent HEK 293T cells using a cationic lipid reagent, and stable integrants were selected by treatment with 200 μg / mL hygromycin B. Clonal populations were obtained from the stable integrant population using limiting dilution or fluorescence-activated cell sorting.
[0235] The cloned stable cell lines were selectively maintained in a constant concentration of 200 μg / mL hygromycin B while being subcultured for use in degradation assays. Flow cytometry analysis using a BD Accuri C6 tube showed that the HEK 293T CMV-IKZF1 clone 7 cell line had an average fluorescein isothiocyanate mean fluorescence intensity (FITC MFI) of 230,000 and a phycoerythrin mean fluorescence intensity (PE MFI) of 33,000. The HEK 293T EF1a-IKZF2 clone 9 had an average FITC MFI of 150,000 and a PE MFI of 26,000. The HEK 293T EF1a-IKZF3 clone 9 had an average FITC MFI of 400,000 and a PE MFI of 60,000. The fluorescence intensities of the IKZF1 / 2 / 3-mNeonGreen (FITC channel) and mScarlet (PE channel) reporters were analyzed periodically by flow cytometry to confirm consistent expression levels between experiments.
[0236] IKZF1 / 2 / 3 reporter degradation assay The IKZF1 / IKZF2 / IKZF3 degradation assay was performed by harvesting the HEK 293T reporter cell line and resuspending the cells in medium (FluoroBrite, Thermo Fisher Scientific) formulated to reduce background fluorescence. Each cell line was seeded at a density of 4000 cells / well in a black-walled, 384-well optical-grade assay tissue culture plate. Cells were incubated overnight at 37°C to allow attachment to the assay plate. Compound dilutions were prepared in DMSO from 10 mM compound stocks. The DMSO dilutions were dispensed into quadruplicate wells of the assay plate, with the appropriate compound concentrations applied, resulting in a final DMSO concentration of up to 0.5%.
[0237] After 24 hours of incubation with compounds, the assay plates were imaged using an ImageXpress Pico microscope system (cells were maintained at 37°C during imaging) to obtain fluorescence readings. The assay plates were imaged in the FITC and tetramethylrhodamine (TRITC) channels to obtain mNeonGreen fluorescence intensity (reporter degradation data) and mScarlet fluorescence intensity (for cell segmentation). The 293T-IKZF1 and 293T-IKZF3 reporter cell lines were imaged using 500 millisecond (ms) exposure times in both the FITC and TRITC channels, while the 293T-IKZF2 reporter cell line was imaged using 1000 ms exposure times in the FITC channel and 1250 ms exposure times in the TRITC channel. The resulting data were analyzed using Cell Reporter Xpress software using a two-channel cell scoring analysis with a "positive rate" readout. The TRITC channel was selected for "nuclei" segmentation, and the threshold was set at 20. Meanwhile, the FITC channel was selected for "Marker 1" segmentation, and the threshold for the IKZF1 and IKZF3 reporter lines was set to 100. For the IKZF2 reporter line, the threshold for the FITC channel was set to 120, and the threshold for the TRITC channel was set to 20. For all cell lines, the minimum segmentation width was set to 6 micrometers, and the maximum segmentation width was set to 15 micrometers. 50 Calculations of were performed by regression analysis using GraphPad Prism to best fit a four-parameter logistic curve.
