AMINOPYRIMIDINE COMPOUNDS CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application No.62/954,899, filed December 30, 2019, and U.S. Provisional Application No.62/968,461, filed January 31, 2020, the entireties of which are incorporated by reference herein. FIELD [0002] Disclosed herein are sulfoximine substituted aminopyrimidine compounds, including pharmaceutical compositions that include one or more aminopyrimidine sulfoximine. BACKGROUND [0003] Various approaches have been employed in the past to block the activity of various tyrosine kinases. These kinase inhibitors are often small molecules. These small molecules can be used to target these kinases to block the development, growth or spread of cancer. [0004] Fibroblast growth factors (FGFs) and their receptors (FGFRs) regulate a wide range of physiologic cellular processes, such as embryonic development, differentiation, proliferation, survival, migration, and angiogenesis. The FGF family comprises 18 secreted ligands (FGFs) which are readily sequestered to the extracellular matrix by heparin sulfate proteoglycans (HPSGs). For signal propagation, FGFs are released from the extracellular matrix by proteases or specific FGF-binding proteins, with the liberated FGFs subsequently binding to a cell surface FGF-receptor (FGFR) in a ternary complex consisting of FGF, FGFR and HPSG (Beenken, A., Nat. Rev. Drug Discov.2009; 8:235-253). [0005] FGFR signaling components are frequently altered in human cancer, and several preclinical models have provided compelling evidence for the oncogenic potential of aberrant FGFR signaling in carcinogenesis, thereby validating FGFR signaling as an attractive target for cancer treatment. [0006] Compounds that inhibit FGFR are needed. SUMMARY [0007] Several embodiments disclosed herein pertain to aminopyrimidine sulfoximine compounds, their use as kinase inhibitors, their methods of manufacture, and their methods of use as therapeutics for treating kinase-related disease states (e.g., cancer). In several embodiments, the aminopyrimidine sulfoximine compound comprises a sulfoximine and an aminopyrimidine. Several embodiments comprise or consist essentially of a sulfoximine compound of the disclosure (or any other structure disclosed herein), their pharmaceutically acceptable salts, enantiomers, methods of manufacture, and/or their methods of use in treating disease states. In several embodiments, by using one or more compounds of the disclosure (or any other structure disclosed herein) to inhibit a kinase in a subject, a disease state can be treated. In several embodiments, the disease state is cancer. In several embodiments, the kinase is a wild-type kinase. In several embodiments, the kinase is a mutant or variant kinase whose activity is not influenced by other standard kinase inhibitors. DETAILED DESCRIPTION [0008] The disclosure may be more fully appreciated by reference to the following description, including the following definitions and examples. Certain features of the disclosed compositions and methods which are described herein in the context of separate aspects, may also be provided in combination in a single aspect. Alternatively, various features of the disclosed compositions and methods that are, for brevity, described in the context of a single aspect, may also be provided separately or in any subcombination. [0009] Several embodiments disclosed herein provide compounds useful in treating diseases caused by dysregulated protein kinase activity. Several embodiments also provide methods of treating diseases utilizing these compounds or pharmaceutical compositions comprising these compounds. In several embodiments, the compounds are sulfoximine compounds. In several embodiments, the sulfoximine functionalities are bound to a core aryl structure. In several embodiments, the core aryl structure is a heteroaryl. In several embodiments, the heteroaryl sulfoximine is an aminopyrimidine. In several embodiments, the heteroaryl sulfoximine compound has a structure as represented by one of the formulas, as shown below. In several embodiments, the disclosed heteroaryl sulfoximines can be used in methods of treating cancer. [0010] As used herein, any “R” group(s) such as, without limitation, R ¹ , R ² , R ³ , etc., represent substituents that can be attached to the indicated atom. An R group may be substituted or unsubstituted. If two “R” groups are described as being “taken together” the R groups and the atoms they are attached to can form a cycloalkyl, aryl, heteroaryl or heterocycle. For example, without limitation, if R ^1a and R ^1b of an NR ^1a R ^1b group are indicated to be “taken together,” it means that they are covalently bonded to one another to form a ring: [0011] Whenever a group is described as being “optionally substituted” that group may be unsubstituted or substituted with one or more of the indicated substituents. Likewise, when a group is described as being “unsubstituted or substituted” if substituted, the substituent(s) may be selected from one or more the indicated substituents. If no substituents are indicated, it is meant that the indicated “optionally substituted” or “substituted” group may be substituted with one or more group(s) individually and independently selected from hydroxy, halogen, an amino, a mono-substituted amino group, and a di-substituted amino group. [0012] As used herein, “C _a to C _b ” or C _a-b in which “a” and “b” are integers refer to the number of carbon atoms in a moiety as described herein. For example, “a” and “b” refer to the number of carbon atoms in an alkyl, alkenyl or alkynyl group, or the number of carbon atoms in the ring of a, e.g., cycloalkyl, , aryl, or heteroaryl group. That is, the alkyl, alkenyl, alkynyl, ring of the cycloalkyl, , ring of the aryl, or the ring of the heteroaryl can contain from “a” to “b”, inclusive, carbon atoms. Thus, for example, a “C1 to C4 alkyl” group or a “C _1-4 alkyl” group refers to all alkyl groups having from 1 to 4 carbons (e.g., 1, 2, 3, or 4), that is, CH ₃ -, CH ₃ CH ₂ -, CH ₃ CH ₂ CH ₂ -, (CH ₃ ) ₂ CH-, CH ₃ CH ₂ CH ₂ CH ₂ -, CH ₃ CH ₂ CH(CH ₃ )- and (CH ₃ )3C-. A “C1 to C6 alkyl” group refers to all alkyl groups having from 1 to 6 carbons (e.g., 1, 2, 3, 4, 5, or 6). If no “a” and “b” are designated with regard to an alkyl, alkenyl, alkynyl, cycloalkyl, aryl, or heteroaryl group, the broadest range described in these definitions is to be assumed. [0013] As used herein, the term “alkyl” refers to a fully saturated aliphatic hydrocarbon group. The alkyl moiety may be branched or straight chain. Examples of branched alkyl groups include, but are not limited to, iso-propyl, sec-butyl, t-butyl and the like. Examples of straight chain alkyl groups include, but are not limited to, methyl, ethyl, n-propyl, n-butyl, n- pentyl, n-hexyl, n-heptyl and the like. The alkyl group may have 1 to 30 carbon atoms (whenever it appears herein, a numerical range such as “1 to 30” refers to each integer in the given range; e.g., “1 to 30 carbon atoms” means that the alkyl group may consist of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 carbon atoms, although the present definition also covers the occurrence of the term “alkyl” where no numerical range is designated). The “alkyl” group may also be a medium size alkyl having 1 to 12 carbon atoms. The “alkyl” group could also be a lower alkyl having 1 to 6 carbon atoms. An alkyl group may be substituted or unsubstituted. By way of example only, “C ₁ -C ₅ alkyl” indicates that there are one to five carbon atoms in the alkyl chain, i.e., the alkyl chain is selected from methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, pentyl (branched and straight-chained), etc. Typical alkyl groups include, but are in no way limited to, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tertiary butyl, pentyl and hexyl.

The alkylene group may also be a medium size alkyl having 1 to 12 carbon atoms. The alkylene group could also be a lower alkyl having 1 to 6 carbon atoms. An alkylene group may be substituted or unsubstituted. For example, a lower alkylene group can be substituted by replacing one or more hydrogen of the lower alkylene group and/or by substituting both hydrogens on the same carbon with a C _3-6 monocyclic cycloalkyl group (e.g., -C- ). [0015] The term “C ₁ -C ₆ alk” when used alone or as part of a substituent group refers to an aliphatic linker having 1, 2, 3, 4, 5, or 6 carbon atoms and includes, for example, -CH ₂ -, - CH(CH ₃ )-, -CH(CH ₃ )-CH ₂ -, and -C(CH ₃ ) ₂ -.

[0133] The FGFR receptors (FGFRl, FGFR2, FGFR3, and FGFR4) share several structural features in common, including three extracellular immunoglobulin-like (Ig) domains, a hydrophobic transmembrane domain, and an intracellular tyrosine kinase domain split by a kinase insert domain, followed by a cytoplasmic c-terminal tail (Johnson et al., Adv. Cancer Res.60:1-40, 1993; and Wilkie et al., Curr. Biol.5:500-507, 1995). In FGFRl, the kinase insert domain spans positions 582 to 595 of the alpha Al isoform of FGFRl. In FGFR2, the kinase insert domain spans positions 585 to 598 of the FGFR2 Ille isoform. In FGFR3, the kinase insert domain spans positions 576 to 589 of the FGFR3 Ille isoform. In FGFR4, the kinase insert domain spans positions 571 to 584 of FGFR4 isoform 1. The c-terminal tail of FGFRs begins following the end of the tyrosine kinase domain and extends to the c-terminus of the protein. Several isoforms of each FGFR have been identified and are the result of alternative splicing of their mRNAs (Johnson et al., Mol. Cell. Biol. 11:4627-4634, 1995; and Chellaiah et al., J. Biol. Chem.269:11620-11627, 1994). [0134] A few of the receptor variants that result from this alternative splicing have different ligand binding specificities and affinities (Zimmer et al., J. Biol. Chem.268:7899-7903, 1993; Cheon et al., Proc. Natl. Acad. Sci. U.S.A.91:989-993, 1994; and Miki et al., Proc. Natl. Acad. Sci. U.S.A.89:246-250, 1992). Protein sequences for FGFR proteins and nucleic acids encoding FGFR proteins are known in the art. Signaling by FGFRs regulates key biological processes including cell proliferation, survival, migration, and differentiation. Dysregulation of a FGFR gene, a FGFR protein, or expression or activity, or level of the same, has been associated with many types of cancer. For example, dysregulation of FGFRs can occur by multiple mechanisms, such as FGFR gene overexpression, FGFR gene amplification, activating mutations (e.g., point mutations or truncations), and chromosomal rearrangements that lead to FGFR fusion proteins. Dysregulation of a FGFR gene, a FGFR protein, or expression or activity, or level of the same, can result in (or cause in part) the development of a variety of different FGFR-associated cancers. [0135] FGFR fusion proteins are known in the art. See, e.g., Baroy et al., PloS One; 11(9):e0163859. doi: 10.1371/journal.pone.0163859, 2016; Ren et al., Int. J.

In some embodiments, the assay is a regulatory agency-approved assay, e.g., FDA-approved kit. In some embodiments, the assay is a liquid biopsy. Additional, non- limiting assays that may be used in these methods are described herein. Additional assays are also known in the art. In some embodiments, the dysregulation of a FGFR gene, a FGFR kinase, or expression or activity or level of any of the same includes one or more FGFR inhibitor resistance mutations. [0161] Also provided herein are methods of selecting a treatment for a subject, wherein the methods include a step of performing an assay on a sample obtained from the subject to determine whether the subject has a dysregulation of a FGFR gene, a FGFR kinase, or expression or activity or level of any of the same (e.g., one or more FGFR inhibitor resistance mutations), and identifying or diagnosing a subject determined to have a dysregulation of a FGFR gene, a FGFR kinase, or expression or activity or level of any of the same, as having a FGFR-associated cancer. Some embodiments further include administering the selected treatment to the subject identified or diagnosed as having a FGFR-associated cancer. For example, in some embodiments, the selected treatment can include administration of a therapeutically effective amount of a compound of the disclosure to the subject identified or diagnosed as having a FGFR-associated cancer. In some embodiments, the assay is an in vitro assay. For example, an assay that utilizes the next generation sequencing, immunohistochemistry, or break apart FISH analysis. In some embodiments, the assay is a regulatory agency-approved, e.g., FDA-approved, kit. In some embodiments, the assay is a liquid biopsy. [0162] Also provided herein are methods of treating a FGFR-associated cancer in a subject that include (a) administering one or more (e.g., two or more, three or more, four or more, five or more, or ten or more) doses of a first FGFR kinase inhibitor to a subject identified or diagnosed as having a FGFR associated cancer ( e.g., any of the types of FGFR-associated cancers described herein) (e.g., identified or diagnosed as having a FGFR-associated cancer using any of the exemplary methods described herein or known in the art); (b) after step (a), determining a level of circulating tumor DNA in a biological sample (e.g., a biological sample comprising blood, serum, or plasma) obtained from the subject; (c) administering a therapeutically effective amount of a second FGFR inhibitor or a compound of the disclosure as a monotherapy or in conjunction with an additional therapy or therapeutic agent to a subject identified as having about the same or an elevated level of circulating tumor DNA as compared to a reference level of circulating tumor DNA (e.g., any of the reference levels of circulating tumor DNA described herein). In some examples of these methods, the reference level of circulating tumor DNA is a level of circulating tumor DNA in a biological sample obtained from the subject prior to step (a). Some embodiments of these methods further include determining the level of circulating tumor DNA in the biological sample obtained from the subject prior to step (a). In some examples of these methods, the reference level of circulating tumor DNA is a threshold level of circulating tumor DNA (e.g., an average level of circulating tumor DNA in a population of subjects having a similar FGFR-associated cancer and having a similar stage of the FGFR-associated cancer, but receiving a non- effective treatment or a placebo, or not yet receiving therapeutic treatment, or a level of circulating tumor DNA in a subject having a similar FGFR-associated cancer and having a similar stage of the FGFR-associated cancer, but receiving a non-effective treatment or a placebo, or not yet receiving therapeutic treatment). In some examples of these methods, the first FGFR inhibitor is: ARQ-087, ASP5878, AZD4547, B-701, BAY1179470, BAY1187982, BGJ398, brivanib, Debio-1347, dovitinib, E7090, erdafitinib, FPA144, HMPL-453, INCB054828, lenvatinib, lucitanib, LY3076226, MAX-40279, nintedanib, orantinib, pemigatinib, ponatinib, PRN1371, rogaratinib, sulfatinib, TAS-120 or RLY-4008.

In some aspects, the additional therapy or therapeutic agent includes one or more of radiation therapy, a chemotherapeutic agent ( e.g., any of the exemplary chemotherapeutic agents described herein or known in the art), a checkpoint inhibitor (e.g., any of the exemplary checkpoint inhibitors described herein or known in the art), surgery (e.g., at least partial resection of the tumor), and one or more other kinase inhibitors (e.g., any of the kinase inhibitors described herein or known in the art). [0164] Compounds of the disclosure may also be useful as adjuvants to cancer treatment, that is, they can be used in combination with one or more additional therapies or therapeutic agents, for example a chemotherapeutic agent that works by the same or by a different mechanism of action. In some embodiments, a compound of the disclosure can be used prior to administration of an additional therapeutic agent or additional therapy. For example, a subject in need thereof can be administered one or more doses of a compound of the disclosure for a period of time and then under go at least partial resection of the tumor. In some embodiments, the treatment with one or more doses of a compound of the disclosure reduces the size of the tumor (e.g., the tumor burden) prior to the at least partial resection of the tumor. In some embodiments, a subject has a cancer (e.g., a locally advanced or metastatic tumor) that is refractory or intolerant to standard therapy (e.g., administration of a chemotherapeutic agent, such as a first FGFR inhibitor or a multikinase inhibitor, immunotherapy, radiation, or a platinum-based agent (e.g., cisplatin)). In some embodiments, a subject has a cancer (e.g., a locally advanced or metastatic tumor) that is refractory or intolerant to prior therapy (e.g., administration of a chemotherapeutic agent, such as a first FGFR inhibitor or a multikinase inhibitor, immunotherapy, radiation, or a platinum-based agent (e.g., cisplatin)). [0165] In some embodiments of any the methods described herein, the compound of the disclosure is administered in combination with a therapeutically effective amount of at least one additional therapeutic agent selected from one or more additional therapies or therapeutic (e.g., chemotherapeutic) agents.

[0173] The active compound may be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual subject, the severity of the subject's symptoms, and the like. In some embodiments, the compounds provided herein can be administered in an amount ranging from about 1 mg/kg to about 100 mg/kg. In some embodiments, the compound provided herein can be administered in an amount of about 1 mg/kg to about 20 mg/kg, about 5 mg/kg to about 50 mg/kg, about 10 mg/kg to about 40 mg/kg, about 15 mg/kg to about 45 mg/kg, about 20 mg/kg to about 60 mg/kg, or about 40 mg/kg to about 70 mg/kg.

In some embodiments, such administration can be once-daily or twice-daily (BID) administration. [0174] In several embodiments, not only can the compounds of the disclosure be used for therapy in patients with FGFR mutations (either point mutations or various fusions) to provide superior benefits, but in situations in which these mutations are likely to arise (such as in erdafitinib and/or infigratinib (BGJ398), pemigatinib, or TAS-120 therapy), where numerous activating and resistance mutations recur in patients, it may be especially advantageous. In several embodiments, the compounds of the disclosure can be used as a therapeutic intervention in patients bearing these mutations, either in combination with a pan- FGFR inhibitor or as a monotherapy where genomic testing supports mutations for which the compounds of the disclosure are active. [0175] In several embodiments, a method of treating a cancer is provided. In several embodiments, the method of treating cancer includes administering one or more compounds of the disclosure. In several embodiments, the method comprises, in response to a determination of the presence of a FGFR mutant polypeptide or a FGFR mutant polynucleotide in a sample from the subject, administering to the subject an effective amount of compounds of the disclosure. This can thereby treat the cancer in the subject. In several embodiments, the FGFR mutant is one of the ones disclosed herein and/or an activating mutant (including a point mutation or FGFR fusion). [0176] In several embodiments, the method of treating cancer includes administering one or more compounds of the disclosure to a patient who is suspected of having a cancer or being at risk of having a cancer. In several embodiments, the method comprises administering to the subject an effective amount of a compound of the disclosure, this can be done with or without a diagnosis or analysis of the subject’s kinases (including whether or not the kinases are wild-type or mutant). [0177] In several embodiments, the FGFR mutants are fusions that can be caused by chromosomal translocations in cancers. These translocations can lead to fusion proteins that exert their oncogenic effects through overexpression or growth factor independent activation of an otherwise normal gene or creation of a chimeric gene in which parts of two genes are fused together. Fusions of FGFR genes with other genes or parts of genes have been found most commonly in FGFR2 and FGFR3. The most common fusion partner reported for FGFR3 is TACC3 (Transforming Acidic Coiled-Coil Containing Protein). [0178] Table 0.1 summarizes the frequency of FGFR specific fusions: TABLE 0.1 [0179] An analysis of FGFR fusions identified in The Cancer Genome Atlas (TCGA) found a number of translocations which illustrate both the recurrence and lack of (absolute) tumor type specificity for FGFR1, 2, and 3 fusions (Table 0.2). Table 0.2

[0180] In several embodiments, mutations in FGFR are polyclonal. Thus, when the FGFR or FGFR-fusion driven cancer metastasizes, the individual metastases can have distinct mutational patterns in the FGFR kinase domain. For example, a patient with distinct liver metastases can have a gatekeeper mutation in a subset of the metastases but not necessarily in all of them at the time of treatment or biopsy. The presence of the founding mutation from the primary tumor i.e. a FGFR fusion would likely remain in all patients. In several embodiments, it is that founding mutation that is targeted by any one or more of the methods provided herein. In several embodiments, both the founding mutation and other mutations are targeted by any one or more of the methods provided herein. In several embodiments, only the later mutations are targeted by one or more of the methods provided herein. In several embodiments, the method of any of the methods provided herein can be one where a compound of the disclosure is administered in an amount adequate to treat a tumor in a subject who has metastasized, and wherein the tumor that is being treated is the primary tumor. In several embodiments, any of the methods provided herein can use an adequate amount of a compound of the disclosure to treat a subset of the tumors in a subject. For example, the subset can include or focus on the tumors with a founding mutation (the primary tumor(s)). Thus, in several embodiments, the therapy need not be directed to, or include an amount of the disclosure to treat every tumor, but just a subset of the tumors (for example the primary tumors with the founding mutation). In several embodiments, the treated tumor is not the primary tumor, but may be a metastases with a detectable resistance or activating mutation not found in the primary tumor. In several embodiments, the method comprises administering the disclosure in an amount adequate to treat a tumor in a subject who has metastasized, and wherein the treated tumor is not the primary tumor, and wherein the treated tumor is a metastases with a detectable resistance or activating mutation not found in the primary tumor. [0181] In several embodiments, a subject with any of the fusion arrangements in Tables 0.1 or 0.2 can obtain an enhanced benefit from a compound of the disclosure therapy. In several embodiments, any of the methods provided herein with respect to various point mutations can be applied to tumors or subjects that have any one or more of the above noted fusions. For example, a method of treating a subject having a cancer can comprise acquiring knowledge of a presence of an FGFR mutation (e.g., fusion) in a FGFR polynucleotide or FGFR polypeptide in said subject. The method can further comprise administering to the subject an effective amount of a compound of the disclosure.

In several embodiments, a compound of the disclosure is at least 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 200, 300, 400, 500, 1000% more potent on the mutant FGFR as on the wild- type FGFR on inhibiting FGFR kinase activity. In several embodiments, the method and/or percent is determined by the method as provided in the present examples. [0186] In several embodiments, a method of treating a subject having a cancer is provided.

In several embodiments, an effective amount of a compound of the disclosure is an amount that reduces the activity of the FGFR mutant to a level that is adequate to provide some treatment to the subject, for example, by reducing one or more symptoms. In several embodiments, the activity of the mutant FGFR is reduced by a compound of the disclosure to near, or lower than, wild-type activity. In several embodiments, the activity for the FGFR mutant, when a compound of the disclosure is administered, is reduced to 500, 400, 300, 200, 190, 180, 170, 160, 150, 140, 130, 120, 110, 105, 104, 103, 102, 101, 100, 95, 90, or lower percent of the activity of wild-type FGFR.

The liganded beads were blocked with excess biotin and washed with blocking buffer SeaBlock (Pierce), 1% BSA, 0.05% Tween 20, 1 mM DTT to remove unbound ligand and to reduce non- specific binding. Binding reactions were assembled by combining kinases, liganded affinity beads, and test compounds in 1x binding buffer (20% SeaBlock, 0.17x PBS, 0.05% Tween 20, 6 mM DTT). [0254] Test compounds were prepared as 111X stocks in 100% DMSO. Kds were determined using an 11-point 3-fold compound dilution series with three DMSO control points. All compounds for Kd measurements are distributed by acoustic transfer (non-contact dispensing) in 100% DMSO. The compounds were then diluted directly into the assays such that the final concentration of DMSO was 0.9%. All reactions performed in polypropylene 384-well plate. Each was a final volume of 0.02 ml. The assay plates were incubated at room temperature with shaking for 1 hour and the affinity beads were washed with wash buffer (1x PBS, 0.05% Tween 20). The beads were then re-suspended in elution buffer (1x PBS, 0.05% Tween 20, 0.5 μM non-biotinylated affinity ligand) and incubated at room temperature with shaking for 30 minutes. The kinase concentration in the eluates was measured by qPCR. Binding constants (Kds) [0255] Binding constants were calculated with a standard dose-response curve using the Hill equation: The Hill Slope was set to -1. Curves were fitted using a non-linear least square fit with the Levenberg-Marquardt algorithm. Cell lines used for Cell Viability Assays   Ba/F3 Cell Viability Assays [0256] Experimental Purpose: Recombinant kinase fusions are transduced into parental Ba/F3, which becomes dependent upon this constitutive kinase activity for IL3-independent survival. Inhibition of kinase activity leads to cell death, which is monitored using CellTiter- Glo® 2.0 (Promega) which measures intracellular ATP concentration that in turn serves as a marker for viability. FGFR1-BCR Ba/F3 and FGFR3-BAIAP2L1 Ba/F3 were obtained from Advanced Cellular Dynamics (Seattle, WA) [0257] Cell Viability Assay Procedure: Cell Titer-Glo® 2.0 Luminescent cell viability assay reagent was purchased from Promega (Madison, WI). FGFR1-BCR Ba/F3 and FGFR3- BAIAP2L1 Ba/F3 cells were cultured in RPMI1640 media supplemented with 10% fetal bovine serum. Cultures were maintained at 37 ^C in a humidified atmosphere of 5% CO ₂ and 95% air. [0258] Cells were plated in 96-well clear bottom/white plates (Corning #3903) at 10,000 cells/well in 100µl of media, incubated overnight. The next day, test compound DMSO stock solutions were made at 10 mM and 2 µM final concentration. Compounds were then added to cells in a 9-dose, 10-fold dilution series starting at 30 µM with an HP 300e Digital Dispenser (each dose was applied in triplicate). DMSO was backfilled to each well up to 301 nL total volume of test compound + DMSO, and a total of 301 nL DMSO was added to a control/no test compound well in triplicate. The cells in cell culture plates were incubated with the compounds at 37 ^C and 5% CO ₂ for 48 hours. Then 50 µl of Cell Titer Glo 2.0 reagent was added to each well of the cell culture plates. The contents were covered from light and mixed on an orbital shaker at room temperature for 10 min. Luminescence was recorded by a Synergy H1 Microplate Reader (Biotek, Winooski, VT ). Cells were assessed as a percentage of DMSO only treated control cells. Curves were plotted and IC ₅₀ values were calculated using the GraphPad Prism 8 program based on a sigmoidal dose-response equation (4 parameter).
