TECHNICAL FIELD

[0003] The present invention relates generally to compounds that inhibit the binding of transcription factors, regulatory regulators, and chromatin to WDR5 and methods of use thereof. In particular embodiments, the present invention provides compositions comprising imino- azacycle-benzamide compounds and methods of use thereof to inhibit or modulate the interaction of WDR5 with chromatin, cognate transcription and other regulatory factors, including for example the histone methyltransferase MLL1, for the treatment of leukemia, solid cancers and other diseases dependent on activity of WDR5.

BACKGROUND

[0004] Mixed lineage leukemia (MLL) presents a heterogeneous group of acute myeloid leukemia and acute lymphoblastic leukemia bearing features of more than one hematopoietic cell lineage. MLL accounts for about 80% of infant acute leukemia cases (Tomizawa, D.; et. al. Leukemia , 2007, 27, 2258-63.) and 10% of all acute leukemia cases (Marschalek, R. Br. J.

Haematol. 2011, 752, 141-54.). MLL leukemia patients have a poor prognosis with overall 5- year survival ratio around 35% (Dimartino, J. F.; Cleary, M. L., Br. J. Haematol. 1999, 106, 614- 626; Pui, C., et al. Leukemia , 2003, 4, 700-706.; Tomizawa, D.; et. al. Leukemia , 2007, 27, 2258- 63.). [0005] MLL is composed of heterogeneous cell lineages with different molecular biology, cell biology and immunology features. However, MLL does share a common feature, which involves the chromosomal rearrangement of Mixed Lineage Leukemia (MLL) gene. MLL gene locates on chromosome 1 lq23 and the encoded MLL protein is a homolog of Drosophila trithorax (Trx) (Thachuk, D. C.; et al. Cell, 1992, 77, 691-700.). Wild type MLL binds to regulatory regions of homeox (HOX) genes (Milne, T. A.; et al. Cancer Res., 2005, 65, 11367- 74.) through the amino terminal fragment while the catalytic C-terminal domain catalyzes the Histone 3 lysine 4 (H3K4) methylation via interaction with WDR5 and up regulates target gene transcription (Nakamura, T.; et al. Mol. Cell, 2002, 10, 1119-28; Yokoyama, A. et al. Mol. Cell Biol., 2004, 24, 5639-49.; Milne, T. A.; et al. Mol. Cell, 2002, 10, 1107-17). Wild type MLL in conjunction with WDR5 is required for maintenance HOX genes expression and is widely expressed not only during embryo development but also in adult tissues including myeloid and lymphoid cells (Yu, B. D.; et al. Proc. Natl. Acad. Sci., 1998, 95, 10632-10636.). Reciprocal translocations of MLL gene result in-frame fusion of the 5’ -end MLL with the 3’ -end of another partner gene. A common feature of MLL 1 abnormality in leukemia is the preservation of one wild-type MLL1 allele. Currently, more than 80 partner genes have been identified, with MLL- AF4, MLL-AF9 and MLL-ENL being the three most frequently found fusion genes (Pui, C., et al. Leukemia, 2003, 4, 700-706; herein incorporated by reference in its entirety). Expression of MLL fusion proteins promotes over expression of target genes such as HOXA9 and MEIS1, which blocks differentiation, enhances blast expansion and ultimately leads to leukemic transformation (Caslini, C.; et al. Cancer Res., 2007, 67, 7275-83.; Yokoyama, A.; et al. Cell, 2005, 123, 207-18.). The numerous chromosomal translocations of MLL gene and partner genes add to the complexity of MLL leukemia treatment. Although HOX9 and MEISl overexpression are commonly observed among MLL leukemia patients, each rearrangement leads to distinct dysregulated target gene expression patterns and downstream events (Slany, R. K.,

Haematologica, 2009, 94, 984-993). Clinical studies reveal that MLL of different chromosomal translocations are associated with different prognosis and are treated differently under current protocols (Tamai, H., et al. J. Clin. Exp. Hematop., 2010, 50, 91-98; Balgobind, B. V., et al. Leukemia, 2011, 8, 1239-1248; Pigazzi, M.; et al. Leukemia, 2011, 25, 560-563).

[0006] Intrinsic histone methyltransferase (HMT) activity of MLL 1 is extremely low and requires a complex assembly of WDR5, RbBP5, ASH2L, and DPY30 protein partners for effective H3K4 trimethylation, the so-called WRAD complex (Patel, A.; et al. J. Biol. Chem ., 2009, 284, 24242-56). The binding of MLL1 to WDR5 (WD40 repeat protein 5) is particularly critical for HMT activity and occurs through a conserved arginine containing motif on MLLl called the“Win” or WDR5 interaction motif. Thus, targeting inhibitors of the MLL1-WDR5 interaction at the WIN site in order to block MLLl methyltransf erase activity could represent a promising therapeutic strategy for treating MLL leukemia patients. Peptidomimetics have been discovered that bind tightly to WDR5 at the MLL site, inhibit MLLl methyltransferase activity, and block proliferation of MLLl cells by inducing cell-cycle arrest, apoptosis, and myeloid differentiation (Cao, F.; et al. Molecular Cell , 2014, 53, 247-61., Karatas, H.; et al. J. Med.

Chem., 2017, 60, 4818-4839.). In addition, altered gene expression patterns similar to MLLl deletion are observed, supporting a role for MLLl activity in regulating MLLl -dependent leukemia transcription. Thus, interruption of the WDR5-MLL1 interaction may be a useful strategy for treating patients with MLL leukemias. In addition to the highly characterized WDR5-MLL1 interaction, disruption of WDR5 with other transcription factors/epigenetic writers or displacement from chromatin itself could have a desirable benefit as a cancer treatment strategy. For example, WDR5 acts as a scaffold protein with the following chromatin

complexes/structures, including histone H3 (via R2 residues, e.g. see Song, J.-L, et al. J. Biol. Chem. 2008, 283, 35258-64), NSL/MOF (Li, X., et al. Molecular and Cellular Biology, 2010, 30, 5335-47., Dias, J., et al. Genes & Development, 2014, 28, 929-942.), C/EBRa p30 (Senisterra,

G., et al. Biochem. J., 2013, 449, 151-159.), c-MYC (Thomas, L. R.; et al. Molecular Cell, 2015, 58, 440-52., herein incorporated by reference in its entirety), and the NuRD complex (Ee, L.-S., et al. Stem Cell Reports, 2017, 8, 1488-96.). In addition, WDR5 expression levels have been reported to be correlative and connected to patient prognosis in several other cancer types, including neuroblastoma (Sun, Y. et al. Cancer Research, 2015, 75, 5143-54.), breast cancer (Dai, X. et al. PLoSOne, 2015, 10, PMC4565643), bladder cancer (Chen, X. et al. Scientific Reports, 2015, 5, 8293.), and colorectal cancer (Tan, X. et al. Cell Death & Disease, 2017, 8, PMC5386518). In addition, in an unbiased shRNA screen in human xenografts, WDR5 was identified as an important target in pancreatic cancer (Carugo, A. et al. Cell Reports, 2016, 16, 133-147.). Based on the growing number of complexes identified which utilize WDR5 to maintain tumor fitness and growth, the emerging importance of WDR5 in several cancer types is not unexpected. In the case of the C-MYC-WDR5 interaction, the MYC oncoprotein utilizes a molecularly defined interaction with WDR5 to bind to its target genes on chromatin. MYC is overexpressed in a majority of malignancies and contributes to an estimated 70,000-100,000 cancer deaths per year in the United States. Thus, disruption of WDR5 from chromatin as a strategy to displace MYC from its target genes may provide a beneficial strategy to treat MYC- driven tumors.

Scheme 1

[0099] In some embodiments, provided compounds of this invention may be prepared as shown in Scheme 1. Optionally substituted 2-amino-3-bromo-5-chlorobenzoic acid 1 is cyclized to 8-bromo-6-chloroquinazolin-4(3//)-one 2 in formamide under the thermal condition. The corresponding quinazolinone NH of 2 can be alkylated by appropriate R¹ group under a number of conditions that are routine for those skilled in the art to give intermediate 3. A variety of boronic acids 4 or borates 5, which are commercially available or can be prepared, can be selectively coupled with intermediates 3 by reacting with the bromo via e.g. , Suzuki -Miyaura coupling protocol to afford biaryl adducts 6 (Miyaura, N., Suzuki, A., Chem.

The commercially available vinyl boronic acid or potassium trifluoro(vinyl)borate can be coupled with intermediates 6 to provide vinyl adduct 7 via e.g., Suzuki coupling protocol for arylchloride developed by Fu (Littke, A. F., Fu, G. C. Angew. Chem. Int. Ed.

The phenol group 22 can be substituted using optionally substituted /c/V-butyl (2-bromoethyl)carbamate in the presence of appropriate bases, such as DIEA, TEA, CS2CO3, or K2CO3 to yield corresponding adduct 23. The Boc group is removed under acidic conditions and the resulting free amine 24 can undergo intramolecular cyclization in the presence of bases, such as DIEA, TEA, CS2CO3, or K2CO3, followed by deprotection of the alcohol to give dihydrobenzo-oxazepinone 25. The hydroxy group of25 can be further elaborated to produce compounds of formula 27a-k using the reaction sequence illustrated in Scheme 1 (intermediate 8 to lOa-k). The intermediate 27a-k can be subjected in Suzuki -Miyaura coupling protocol, depicted in Scheme 1, using boronic acids 4 or borates 5 to afford biaryl adducts 28a - k. Finally, the NH- of28a - k core unit can be substituted by appropriate R¹ groups using a number of conditions that are routine for those skilled in the art to give compounds of formula 30a-k. Alternatively, the reaction sequence can be switched by alkylation the NH of27a-k prior to Suzuki-Miyaura coupling reaction.

Scheme 4

[00102] Alternatively, the intermediate 31 with a protected hydroxyl group can be subjected in Suzuki -Miyaura coupling protocol followed by substitution of NH of32 as illustrated in Scheme 3 to give the intermediate 33. Then, the protecting group of33 can be removed under various conditions that are routine for those skilled in the art of organic synthesis. The resulting hydroxyl group of 33 can be further elaborated to produce compounds of formula 30a-k using the reaction sequence shown in Scheme 1.

Scheme 5

[00103] In some embodiments, compounds of Formula 37a-k and 40a-k encompassing R’ or R’’ groups with defined stereo-configurations may be synthesized by procedures illustrated in Scheme 5.

Similarly, the same reaction protocol can be applied using 4-R”-l,2,3-oxathiazolidine-2,2- dioxide reagent 38 to generate the intermediate 39 with retention of configuration. Then, resulting intermediates 36 and 39 can be subjected to reaction sequences illustrated in Schemes 3 and 4 to produce final compounds 37a-k and 40a-k. Scheme 6.

[00104] Exemplary methods for preparing compounds of Formula 45a-k and 46a-k, containing dihydro-benzodiazepine-dione and tetrahydro-benzodiazepin-one core unit respectively, are shown in Scheme 6 and proceed from optionally substituted 2-amino-3-bromo-5-chlorobenzoic acid 1. Amide coupling reaction with R¹ -substituted aminoacetate 41 using coupling reagents including, but not limited to, HATU, EDC, PyBOP, DCC, HBTU, or TBTU under a number of conditions that are routine for those skilled in the art of organic synthesis gives amide 42.

Subsequent intramolecular cyclization of 42 in the presence of base, such as KOtBu, can produce dihydro-benzodiazepine-dione 43. The reaction sequence demonstrated in Scheme 1 can be applied to prepare dione 45a-k, which can be converted to compounds of Formula 46a-k by hydride reduction reaction using, but not limited to, NaBFE, NaBH(OAc)3 or NaCNBFE.

Scheme 7.

[00105] Alternatively, compounds of Formula 45a-k may be prepared by procedures illustrated in Scheme 7. The synthesis is started from optionally substituted 2-amino-3-bromo-5- iodobenzoic acid 47, which can undergo 2 subsquent Suzuki-Miyaura coupling protocols outlined in Scheme 1 in region-selective manner to provide Intermediates 48 and 49.

Saponification followed by amide coupling reaction described previousely gives amide 50. Subsequent intramolecular cyclization using, but not limited to, chloroacetyl chloride through amide formation of the aniline moiety followed by alkylation of the benzamide group in the presence of base, such as NaH, can produce dihydro-benzodiazepine-dione 51. Dione 45a-k may be produced following the reaction sequence demonstrated in Scheme 1

Scheme 8.

[00106] In some embodiments, compounds of Formula 60a-k containing aromatic R¹ group (Ar²) may be synthesized by procedures illustrated in Scheme 8. Reduction of optionally substituted methyl 3-bromo-5-formyl-2-hydroxybenzoate 21 as shown in Scheme 3 can produce alcohol 53, where the phenol group can be selectively alkylated using te/V-butyl (2- bromoethyl)carbamate in the presence of appropriate bases such as K2CO3 to yield

corresponding adduct 54. Boronic acids 4 or borates 5 may be coupled under the Suzuki-Miyaura coupling protocol outlined in Scheme 1 followed by removal of Boc protecting group to afford biaryl intermediate 18. Subsquent intramolecular cyclization in the presence of base such as (i- R EΐN under thermolysis condition may yield oxazepinone intermediate 56. Intermediate 58a-k may be produced using the reaction sequence illustrated in Scheme 1 to install desired R⁸ group from alcohol 56. The lactam NH of 58a-k may undergo cross-coupling reactions with a variety of aryl or heteroaryl halides of formula 59, wherein Y is Br or I, in the presence of a catalytic Pd species, such as Pd(OAc)2 or Pd2(dba)3 and a suitable ligand such as Xantphos or BrettPhos and a base such as Na2CCb, CS2CO3, or K2CO3 to generate compounds of formula 60a-k.

Alternatively, compounds of formula 60a-k can be also produced using the Ullman coupling conditions in the presence of Cul and a suitable ligand such as (trans)-l,2·/^/^ - dimethylaminocyclohexane or Z-Proline and a base such as CS2CO₃, K2CO₃ or K2PO4 in a suitable solvent such as toluene or DMF.

3. Pharmaceutical compositions

[00340] The disclosed compounds may be incorporated into pharmaceutical compositions suitable for administration to a subject (such as a patient, which may be a human or non-human).

[00341] The pharmaceutical compositions may include a“therapeutically effective amount” or a“prophylactically effective amount” of the agent. A“therapeutically effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired therapeutic result. A therapeutically effective amount of the composition may be determined by a person skilled in the art and may vary according to factors such as the disease state, age, sex, and weight of the individual, and the ability of the composition to elicit a desired response in the individual. A therapeutically effective amount is also one in which any toxic or detrimental effects of a compound of the invention [e.g., a compound of formula (I)] are outweighed by the therapeutically beneficial effects. A“prophylactically effective amount” refers to an amount effective, at dosages and for periods of time necessary, to achieve the desired prophylactic result. Typically, since a prophylactic dose is used in subjects prior to or at an earlier stage of disease, the prophylactically effective amount will be less than the therapeutically effective amount. [00342] For example, a therapeutically effective amount of a compound of formula (I), may be about 1 mg/kg to about 1000 mg/kg, about 5 mg/kg to about 950 mg/kg, about 10 mg/kg to about 900 mg/kg, about 15 mg/kg to about 850 mg/kg, about 20 mg/kg to about 800 mg/kg, about 25 mg/kg to about 750 mg/kg, about 30 mg/kg to about 700 mg/kg, about 35 mg/kg to about 650 mg/kg, about 40 mg/kg to about 600 mg/kg, about 45 mg/kg to about 550 mg/kg, about 50 mg/kg to about 500 mg/kg, about 55 mg/kg to about 450 mg/kg, about 60 mg/kg to about 400 mg/kg, about 65 mg/kg to about 350 mg/kg, about 70 mg/kg to about 300 mg/kg, about 75 mg/kg to about 250 mg/kg, about 80 mg/kg to about 200 mg/kg, about 85 mg/kg to about 150 mg/kg, and about 90 mg/kg to about 100 mg/kg.

[00343] The pharmaceutical compositions may include pharmaceutically acceptable carriers. The term "pharmaceutically acceptable carrier," as used herein, means a non-toxic, inert solid, semi-solid or liquid filler, diluent, encapsulating material or formulation auxiliary of any type. Some examples of materials which can serve as pharmaceutically acceptable carriers are sugars such as, but not limited to, lactose, glucose and sucrose; starches such as, but not limited to, com starch and potato starch; cellulose and its derivatives such as, but not limited to, sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt;

4. Methods of Treatment

[00380] Mixed lineage leukemia (MLL) presents a heterogeneous group of acute myeloid leukemia and acute lymphoblastic leukemia bearing features of more than one hematopoietic cell lineages. MLL accounts for about 80% of infant acute leukemia cases (Tomizawa, 2007) and 10% of all acute leukemia cases (Marschalek, 2011). MLL leukemia patients have a poor prognosis with overall 5-year survival ratio around 35% (Dimartino, 1999; Pui, 2003; Tomizawa, 2007).

[00381] MLL is composited of heterogeneous cell lineages with different molecular biology, cell biology and immunology features. However, MLL does share a common feature, which involves the chromosomal rearrangement of Mixed Lineage Leukemia (MLL) gene. MLL gene locates on chromosome 1 lq23 and the encoded MLL protein is a homolog of Drosophila trithorax (Trx) (Thachuk, 1992). Wild type MLL binds to regulatory regions of homeox (HOX) genes (Milne, 2005) through the amino terminal fragment while the catalytic C-terminal domain catalyzes the Histone 3 lysine 4 (H3K4) methylation via interaction with WDR5 and up regulates target genes transcription (Nakamura, 2002; Yokoyama, 2004; Milne, 2002). Wild type MLL in conjunction with WDR5 is required for maintenance HOX genes expression and is widely expressed not only during embryo development but also in adult tissues including myeloid and lymphoid cells (Butler, 1997;Yu, 1998). Reciprocal translocations of MLL gene result in-frame fusion of 5’ -end MLL with the 3’ -end of another partner gene. A common feature of MLL 1 abnormality in leukemia is the preservation of one wild-type MLL1 allele. Currently, more than 80 partner genes have been identified, with MLL-AF4, MLL-AF9 and MLL-ENL being the three most frequently found fusion genes (Pui, 2003; herein incorporated by reference in its entirety). Expression of MLL fusion proteins promotes over expression of target genes such as HOXA9 and MEIS1, which blocks differentiation, enhances blast expansion and ultimately leads to leukemic transformation (Caslini, 2007;Yokoyama, 2005). The numerous chromosomal translocation of MLL gene and partner genes diversity add to the complexity to MLL leukemia treatment, though HOX9 and MEISl overexpression are commonly observed among MLL leukemia patients, each rearrangement leading to distinct dysregulated target gene expression patterns and downstream events (Slany, 2009). Clinical studies reveal that MLL of different chromosomal translocations are associated with different prognosis and are treated differently under current protocols (Tamai, 2010; Balgobind, 2011; Pigazzi, 2011).

[00382] Intrinsic HMT activity of MLLl is extremely low and requires a complex assembly of WDR5, RbBP5, ASH2L, and DPY30 protein partners for effective H3K4 trimethylation, so called WRAD complex. The binding of MLLl to WDR5 (WD40 repeat protein 5) is particularly critical for HMT activity and occurs through a conserved arginine containing motif on MLLl called the“Win” or WDR5 interaction motif. Thus, targeting inhibitors of the MLL1-WDR5 interaction at the WIN site in order to block MLLl methyltransf erase activity could represent a promising therapeutic strategy for treating MLL leukemia patients. Peptidomimetics have been discovered that bind tightly to WDR5 at the MLL site, inhibit MLLl methyltransferase activity, and block proliferation of MLLl cells by inducing cell-cycle arrest, apoptosis, and myeloid differentiation (Cao, et al. Molecular Cell, 2014, 53, 247-261.) In addition, altered gene expression patterns similar to MLLl deletion are observed, supporting a role for MLLl activity in regulating MLLl -dependent leukemia transcription. Thus, interruption of the WDR5-MLL1 interaction may be a useful strategy for treating patients with MLL leukemias. The molecules described herein will target this interaction and could provide an attractive therapeutic approach to develop novel drugs for leukemias with translocations of MLL gene and other leukemias with upregulation of target genes. It also appreciated that WDR5 has been implicated in other cancer types and may utilize the WIN-site for other chromatin regulatory complexes outside and/or overlapping with WRAD complex. As such the WIN-site inhibitors described herein may have utility in multiple cancer types through mechanisms of action involving both direct competitive WIN-site antagonism, or through allosteric inhibition of higher complexes wherein WDR5 is dependent for their proliferative activity and tumor formation. Examples include breast cancer (Dai, X. et al. PLoS One, 2015), MYC-driven tumor types (Thomas, et al. Molecular Cell, 2015), bladder cancer (Chen, X. et al. Nature, Scientific Reports, 2015), neuroblastoma (Sun, Y. et al. Cancer Research, 2015), and pancreatic cancer (Carugo, A. et al. Cell Reports, 2016).

[00383] The disclosed compounds and compositions may be used in methods for treatment of MLL related cancers. The methods of treatment may comprise administering to a subject in need of such treatment a composition comprising a therapeutically effective amount of the compound of formula (I).

5. Biological Activity

[00400] The in vitro modulation of WDR5 protein was determined as follows.

MLL Peptide Binding Assay

General

[00401] Provided compounds of the present invention can be demonstrated to compete for binding with fluorescently labeled peptides derived from relevant MLL protein.

Time Resolved-Fluorescence Energy Transfer Competition Assay

[00402] A Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) assay that measures the displacement of the lOmer-Thr-FAM probe in response to compound treatment was performed for compounds wherein the ICso from FPA assay using lOmer-Thr-FAM was below the lower assay ICso limit ~1 nM. Excess lOmer-Thr-FAM probe was utilized with His-tagged WDR5 in conjunction with a commercial anti-His antibody containing a Terbium label. The LanthaScreen™ Elite Tb-anti-HIS Antibody from ThermoFisher Scientific was used for this purpose. This Tb-anti-HIS has an excitation/emission of 340 nm and 490 nm, respectively. The lOmer-Thr-FAM probe when bound to WDR5 will undergo a FRET interaction with the Tb-anti- HIS and emit at 520 nm. The ratio of the 520 and 495 signals are then utilized to generate a dose-response curve to calculate an ICso value. By virtue of FRET there is little to no background fluorescence interference from lOmer-Thr-FAM probe allowing an excess of the probe to be used permitting an increase in the lower limit of the calculated Ki when testing against highly potent inhibitors with Ki « 1 nM. WDR5-His Tag (D23, residues 24-334) is expressed and purified in our lab in sufficient quantities for screening. lOmer-Thr-FAM peptide is used at 150 nM. WDR5-His tag protein is used at 2 nM. A source plate is prepared using an Echo Liquid Handler, which distributes the compounds to the assay plate (white, flat-bottom; OptiPlate) in a 10-point, 5-fold dilution schemes with a top concentration of 5mM, in a final volume of 20 pL. A final target (WDR5) / Tb-Ab concentration of 2 nM / 1 nM is dispensed from appropriate stock solutions, respectively. The final DMSO concentration in each well of the assay plate is 1% or lower. The plate is covered, shielded from light, and incubated for 60 minutes at room temperature with rocking. lOmer-Thr-FAM and Anti -His terbium antibody fluorescence is then measured on a Biotek Cytation 3 at excitation wavelength of 340 nm, and emission wavelengths of 495 nm and 520 nm. Working buffer conditions contain IX Phosphate Buffered Saline, 300mM NaCl, 0.5mM TCEP, 0.1% CHAPS, at pH 7.2. TR-FRET signal is plotted and ICso and Ki values are calculated according to the formula of Wang Z. FEBS Lett (1996) 3, 245.

Ki = [I]5o/([L]₅o/Kd + [P]o/K_d + 1)

where [I]so is the concentration of the free inhibitor at 50% inhibition, [L]so is the concentration of the free labeled ligand at 50% inhibition, [P]o is the concentration of the free protein at 0% inhibition, K_d represents the dissociation constant of the FITC-MLL or lOmer-Thr-FAM probe for WDR5. Total fluorescence is also measured, to rule out compounds that are inherently fluorescent or able to act as quenchers in the assay.

TR-FRET binding assay

[00403] Table 2. Ki for Exemplified Compounds for Inhibition of WDR5 by TR-FRET assay

[00404] Among other things, these data demonstrate the utility of representative compounds as selective inhibitors of the activity of WDR5 protein to bind peptides from relevant MLL domain.

Cellular Viability of Human Tumor Cell Lines

[00405] Anti-proliferative activity using MLL-harboring cell lines. MV-4-11 and K562 cells are grown in IMDM media supplemented with 10% FBS and 1% penicillin/streptomycin, Molm- 13 cells are cultured in RPMI-1640 media supplemented with 10% FBS and 1%

penicillin/streptomycin. Viability assays are performed by dispensing 200 cells at 7200 cells/mL into each well of an opaque 384-well plate and adding compounds at the indicated concentrations in a final volume of 32 pL and a final concentration of DMSO of 0.3 % for all samples. A certain range of compound concentrations is made through a series of 2-fold dilutions starting 30 pM at the highest, total 22 dilutions. After a set incubation period, 5 day protocol, the viability of cells in each well is assessed using the CellTiter-Glo assay (Promega), read on a 96 Microplane Luminometer (Cytation 3, BioTek). Serial dilutions of each cell type are performed in all assays to generate standard curves and the final densities of cells are determined within the dynamic range of the instrument. . GLo values are calculated based on XL/// software (IDBS, Guildford, UK) with Sigmoidal Dose-Response Model. Each compound is tested in minimum of two replicates. Data are expressed as mean.
