An inactive benzophenone (KI-MS2-073) and an active diazirine compound (KI-MS2-085) are shown in FIG. 8A. Clicking on AlexaFluor to KI-MS2-085 illuminates a 20 kDa band in live cell treatments. The active compound illuminates two bands at 20 kDa, which is the molecular weight of two Max isoforms. These bands overlap with western blot detection of Max (FIG. 8B). The interaction is competed when 20 M soluble KI-MS2-008 compound is present. Another non-selective band appears for both the active and inactive analogues.

(12) FIGS. 9A to 9B show target engagement in live cells using KI-MS2-085 clicked on Biotin with Streptavidin Enrichment. Clicking on Biotin to KI-MS2-085 followed by Streptavidin enrichment yielded Max protein enrichment by western-blot (FIG. 9A). A coomassie total protein stain is also shown (FIG. 9B).

(13) FIG. 10 shows a general schematic for Co-IP MS experiment to investigate mechanism of action of KI-MS2-008: Whole cell lysate was generated and a Max-anchored co-immunoprecipitation was performed when KI-MS2-008 was or was not added to the cell lysate. Proteins bound to anti-Max beads were identified via mass spec with tandem mass tagging (TMT) based quantification.

(14) FIG. 11 shows an immunoblot against c-Myc and Max (c-Myc: 9E10, Santa Cruz Biotechnology; Max: H-2, Santa Cruz Biotechnology). Max was immunoprecipitated and c-Myc was co-immunoprecipitated using the -Max antibody both in the presence and absence of KI-MS2-008, but not with control antibody. P493-6 cells were washed twice with cold PBS and resuspended in modified RIPA buffer (200 mM NaCl, 50 mM Tris, 1% NP-40, 0.1 g/100 mL sodium deoxycholate, protease inhibitor cocktail, phosphatase inhibitor, 0.4 L benzonase per 10 mL buffer, pH 7.5) at a density of about 50 million cells per mL of modified RIPA buffer. Cell resuspensions were vortexed briefly and left on ice for 20 min. The mixture was spun down at 14,000 g for 10 min at 4 C. The supernatant following centrifugation was the whole cell lysate. Protein concentrations were estimated via Bradford assay and 4 mg of total protein was incubated with 2 L DMSO or 10 mM KI-MS2-008 for 30 min before adding -Max antibody or control antibody. After an overnight incubation at 4 C., 50 L of washed Dynabeads Protein G for Immunoprecipitation (ThermoFisher Scientific) were added and allowed to incubate for 1 hour at 4 C. Beads were collected and washed three times with wash buffer. For one replicate of beads, 30 L of 2 Laemmli sample buffer with 2-mercaptoethanol was added and boiled at 90 C. for 5 min to elute. Samples were run on a gel and an immunoblot against c-Myc and Max was generated (c-Myc: 9E10, Santa Cruz Biotechnology; Max: H-2, Santa Cruz Biotechnology). Max was immunoprecipitated and c-Myc was co-immunoprecipitated using the -Max antibody both in the presence and absence of KI-MS2-008, but not with control antibody.

(15) FIG. 12 shows interactomics data of -Max Ab (KI-MS2-008)/control IgG in a scatterplot. In this scatterplot, each dot represents a protein. Proteins that appear in the upper right quadrant are enriched in the first condition, while those that appear in the bottom left quadrant are enriched in the second condition. Some known interactors of Max are shown enriched in the Max Co-IP.

(16) FIG. 13 shows interactomics data of -Max Ab (+KI-MS2-008)/control IgG in a scatterplot. In the presence of KI-MS2-008, similar proteins are enriched when -Max antibody is used compared to the control antibody.

(17) FIG. 14 shows the impact of KI-MS2-008 on Max interactome in a scatterplot. When comparing the Max interactome in the presence of KI-MS2-008 compared to its absence, perturbed proteins can be identified for follow-up studies.

(18) FIGS. 15A to 15C show KI-MS2-008 Max Homodimer Stabilization Hypothesis for MoA. FIG. 15A shows electrophoretic mobility shift assays (EMSAs), which demonstrate that KI-MS2-008 does not disrupt the c-Myc/Max heterodimer. FIG. 15B shows an EMSA experiment with recombinant Max, which revealed a dose-dependent increase of Max homodimer binding to DNA. This leads to a hypothesize that KI-MS2-008 stabilizes the Max homodimer. FIG. 15C shows further evidence of this by quantifying the relative populations of the Max monomer vs. Max homodimer by fPLC. Addition of KI-MS2-008 induced dimerization of the Max homodimer by 9.9%.

(19) FIGS. 16A to 16B show that KI-MS2-008 decreases Myc protein levels (FIG. 16A), which can be recovered by Proteasome inhibition (FIG. 16B).

(20) FIG. 17 shows data for MS2 degronimids first-generation molecules.

(21) FIG. 18 shows qPCR data, which indicates that KI-MS2-008 decreases Myc transcript levels.

(22) FIG. 19A to 19B shows that KI-MS2-008 perturbs transcriptional programs. In particular, RNA-seq shows a strong clustering of cell lines and time points with decent clustering of conditions. P493-6 shows relatively sensitive engineered cell line in viability assay. 10 M treatment clustered closely with doxycycline treatment, especially at the 8 hour time point. P3HR1 shows relatively insensitive (IC50 51.15 M) non-engineered cell line in viability assay. Minimal perturbations to the transcriptome. ST-486: relatively sensitive (IC50 18.71 M) non-engineered cell line in viability assay. Clear perturbations to transcriptome at 45 min.

(23) FIGS. 20A to 20C show transplanted Luc-labeled cells from MYC-driven lymphoma model into immune-compromised NSG mice. FIG. 20B shows IV administration of 20 M in saline+0.1% DMSO, 150 L daily dose. FIG. 20C shows IP administration of 10 mg/mL in corn oil, 100 L IP, dosed every other day (d2-16); pre-treatment of 4188-Luc cells with 20 M in PBS+0.1% DMSO for 24 hours. The data demonstrates that KI-MS2-008 impacts tumor volume in MYC-driven T-ALL model.

(24) FIG. 21 shows the results of a LC/MS detection method for MS2-008. The compound peak was detected at 9 minutes.

(25) FIG. 22 shows the results of a serial dilution-lowest detection limit test. The data demonstrates that MS2-008 is detectable in processed plasma. n=3 mice for each group. Paired t-test between control plasma and other sample sets: *p<0.001.

(26) FIG. 23 shows LC/MS analysis for compound IV and oral administration comparison.

(28) FIG. 25 shows animal weight during a treatment wherein healthy mice were dosed orally with cyclodextrin vehicle or MS2-008 compound, for 7 days. Results indicate that there was no significant change in body weight during the course of compound treatment. n=5 per group.

(29) FIG. 26A shows a graph, which indicates that plasma levels of MS2-008 increase slightly following repeated oral dosing. A positive control of plasma collected at 30 minutes of 0.731 mg/kg (200 mM) dosed mice was used. n=5 per group. The inset chart shows data without the positive control sample. FIG. 26B shows pharmacodynamics results following oral delivery of 200 M of compound MS2-008 in cyclodextrin. Compound MS2-008 was administered PO at 150 ul of 200 M MS2-008 in 20% cyclodextrin+1.4% DMSO, where blood samples were collected from three animals for vehicle control, 30 min, 1, 2, 4, 6 and 24 hours post compound administration. Animals were euthanized and tissues (liver, kidney, spleen, heart and muscle) were collected and snap frozen on dry ice. Plasma was isolated from the blood samples and frozen. Plasma samples were processed and subjected to LC/MS analysis to determine compound levels. n=3 animals per group for each time point. Sets 1-3 are independent sample processing and LC/MS runs of plasma at each time point.

Recombinant human Max protein (ab95309) was dialyzed in 20 mM Tris three times to stabilize the chemical potential of the protein. Two samples were prepared for the experiment. Max protein (0.25 mg/mL) and Max protein pre-incubated one hour with 10 M MS2-008 were added to the analytical ultracentrifugation (AUC) assembly cells. The assembly cells were positioned into a Beckman XL-I Analytical Ultracentrifuge and centrifuged at 42,000 rpm at 20 C. A sedimentation velocity experiment was started scanning A.sub.280 every 1.2 minutes for 18 hours. The data was analyzed with SedFit software by fitting the data with the continuous c(s) distribution model with at a 150 resolution and one sigma confidence level. Untreated Max protein has sedimentation coefficients (c(s)) of 1.574 and 2.593 signifying the monomer and homodimer, respectively, at a 1:6 ratio. Pre-incubating the protein with 10 M MS2-008 shifted the distribution to predominantly the Max homodimer at a c(s) of 2.345 with a slight shouldering towards 1.5.

Example 2. Cell Viability Assay of Exemplary Compounds Described Herein

(345) The effect of Compound 1 on cell viability in several cancer cell lines and normal human astrocytes (NHA) was determined. The cancer cell lines employed in the assay included those corresponding to Burkitt's lymphoma (ST486 and CA46), small cell lung cancer (NCI-H1963), and glioblastoma (GBM4). The cell viability of normal human astrocytes (NHA) was also assayed. Exemplary results are shown in FIG. 2, where viability was assessed by CELL TITER GLO assay (Promega). Compound 1 demonstrated an effect in cell viability in a variety of cancer cell lines, consistent with the notion that Myc is a key oncoprotein in a broad range of cancers. The effects of other compounds described herein on cell viability in several cancer cell lines were also determined, and exemplary results are shown in Table 2, where viability was assessed by CELL TITER GLO assay (Promega).

Example 3. Selectivity of Exemplary Compounds Described Herein for Cells Expressing Myc

(346) The selectivity of Compound 1 for cells expressing Myc over non-Myc expressing cells in cancer cell line P493-6 (engineered cell line derived from human B-cells) was determined. Adding doxycycline to P493-6 growth media shuts off Myc transcription [9]. Exemplary results are shown in FIGS. 3A to 3B, where cell viability was assessed by CELL TITER GLO assay (Promega). FIG. 3A depicts the assay results for cells expressing Myc, and FIG. 3B depicts the assay results for non-Myc expressing cells. Compound 1 demonstrated a selectivity for cells expressing Myc and exhibited decreased cell viability, compared to non-Myc expressing cells in cancer cell lines. The selectivity of other compounds described herein in cancer cell line cancer cell line P493-6 was also determined, and exemplary results are shown in Table 2, where viability was assessed by CELL TITER GLO assay (Promega).

Example 4. Target Identification Experiments of Exemplary Compounds Described Herein

(347) In order to explore the mechanism of action of Compound 1, preliminary target identification experiments involving affinity-based pull downs were carried out. Compound 1 was modified to include a biotinylated probe, which had been shown to be tolerated during an evaluation of select compounds (Table 2). Compound 5 contains a biotinylated probe, and was found to have an IC.sub.50 value of 5.4 M in Myc reporter assay. The structure of Compound 5 allowed for linking Compound 1 to beads (streptavidin agarose, Pierce, Thermo Fisher after Scientific). After incubating the loaded beads with pure MAX protein and Compound 1, which was unbound to the beads and acted a soluble competitor, followed by a pull down of the beads and subsequent analysis by Western blot of c-Myc levels, there was less MAX pulled down in the presence of Compound 1 as a soluble competitor (FIG. 4A). After incubating the loaded beads with nuclear lysate, followed by a pull down of the beads and subsequent analysis by Western blot of c-Myc levels, MAX was pulled down and c-Myc was co-precipitated (FIG. 4B). This suggests that Compound 1 is may bind to MAX in pure protein solution and in cell lysates.

Example 5. Synthesis of KI-MS2 Pulldown Reagent

(348) ##STR00311##

(349) 50 L of Pierce NHS-Activated Magnetic Beads (ThermoFisher Scientific) were washed three times with 500 L DMSO. 100 L of DMSO was added to the washed beads, along with 0.5 L of 10 mM KI-MS2-081 or 0.5 L of DMSO for the empty beads and 0.75 L triethylamine. This reaction mixture was incubated overnight at room temperature. Next, 2.5 L of aminoethanol was added to each set of beads to block unreacted NHS groups. The following day, beads were washed three times with 500 L DMSO, followed by three washes with 500 L wash buffer (150 mM NaCl, 50 mM Tris, protease inhibitor cocktail, phosphatase inhibitors, pH 7.5).

A linear gradient was used: 0-0.5 min 0% B; 0.5-10.5 min 0-100% B; 10.5-15.5 min 100% B; 15.5-17.5 min 100-0% B; run stopped at 23 min. Flow rate was 0.4 ml/min and injection volume was 10 l. The mass spec (Sciex API4000) was operated under multiple reaction monitoring mode scanning for the 4 most prominent fragments of the compound: m/z105.1, 519.1, 416, 205.1 (blue, red, green, and grey, respectively). The parameters were: curtain gas 25 units; ion source gas 1, 30 units; ion source gas 2, 30 units; temperature 550 C.; ion spray voltage 5500 V; declustering potential 96 V, and collision energy 57 eV. The results are shown in FIG. 21 and demonstrate that LC/MS methods for compound detection were found and developed.

Example 6Plasma Extraction Method for Non-Polar Compounds

(351) Samples of 10 l plasma were extracted in eppendorf tubes by quickly adding 500 l of cold MeOH, followed by 300 l cold water, and 500 l cold chloroform. The tubes were mixed by hand for a few seconds, vortexed at max speed for 10 min at 4 C., and then centrifuged for 5 min at max speed at 4 C. The chloroform layer (bottom layer) was transferred to a new tube and evaporated in a SpeedVac. The tubes were frozen at 80 C. until LCMS analysis.

Example 7MS2-008 is Detectible in Processed Plasma

(352) A plasma protein binding study was conducted to determine if the MS2-008 compound has high or low protein extraction using the above plasma extraction method. Plasma was processed from blood samples. Water and plasma samples were spiked with MS2-008 and subjected to the plasma extraction protocol. Preliminary results showed minimal differences between extraction from water or plasma.

(353) A serial dilution-lowest detection limit test was also conducted. A serial dilution of the MS2-008 compound was made in plasma samples from each animal. Plasma samples were frozen and then the desired compound was extracted from the plasma using the method described above. Approximately 0.6 M seems to be the lowest reliable detectable concentration. n=3 mice for each group. Paired t-test between control plasma and other sample sets: *p<0.001 (FIG. 22). The results shown in FIG. 22 indicate that MS2-008 is detectable in processed plasma.

(354) In view of the above results, compound extraction from plasma methods was developed. Plasma and blood do not seem to significantly bind compound and compound detection limits from plasma were determined (>0.6 M).

Example 8Compound IV and Oral Comparison

(355) Previously, a significant effect on tumor development was observed in animals dosed via I.V. but not oral or IP formulations in corn oil. As such, to the aim was to determine how much compound is present in the blood at 1 hour post administration (IV or PO). The same dose of MS2-008 compound for PO administration with the IV saline vehicle and in 20% cyclodextrin, a common oral vehicle was also used. MS2-008 administered at 150 l of 20 uM MS2-008 in saline+0.1% DMSO for IV and oral saline; 20 M MS2-008 in 20% cyclodextrin+0.1% DMSO.

(356) MS2-008 administered at 150 l of 20 uM MS2-008 in saline+0.1% DMSO for IV and oral saline; 20 M MS2-008 in 20% cyclodextrin+0.1% DMSO. Blood samples were collected in EDTA tubes 1 hour post administration, spun, and then the plasma was collected and processed for LC/MS analysis. The results, as shown in FIG. 23, indicate a demonstrable level of compound with IV and no significant change in oral saline or cyclodextrin as compared to control plasma. n=3 animals for each group; paired t-test between control plasma and other sample sets: *p<0.001 (see FIG. 23).

Example 9Pharmacodynamics Following Oral Delivery of 200 M of MS2-008 in Cyclodextrin

(357) Compound MS2-008 was administered PO at 150 ul of 200 M MS2-008 in 20% cyclodextrin+1.4% DMSO. Blood samples were collected from three animals for vehicle control, 30 min, 1, 2, 4, 6 and 24 hours post compound administration. Animals were euthanized and the tissues (liver, kidney, spleen, heart and muscle) were collected and snap frozen on dry ice. The plasma was isolated from the blood samples and frozen. Plasma samples were processed and subjected to LC/MS analysis to determine compound levels. n=3 animals per group for each time point. Sets 1-3 are independent sample processing and LC/MS runs of plasma at each time point. (See FIG. 26B).

(358) Drug clearance is rapid for the first couple of hours between 30 min and 1 hour the concentration drops 50% and between 1-2 hours it drops another 50%. The compound concentration then remains relatively stable between 2 and 6 hours and drops back to non-detectable by 24 hours.

Example 10No Toxicity was Observed Following Repeated Dosing of MS2-008

(359) Healthy mice were dosed orally with cyclodextrin vehicle, 0.364 mg/kg (100 mM) or 0.731 mg/kg (200 mM) compound daily for 7 days. Animal weights were acquired each day. On day 8, blood samples were collected to look at plasma concentration of compound. Mice were then euthanized and liver and kidneys were preserved in formalin for H&E staining to look at cellular indicators of toxicity. Histology slides were observed by a certified pathologist. n=5 per group.

(360) Animal weights and behavioral observations indicated that there was no significant change in body weight or behavior were observed during the course of compound treatment (see FIG. 25).

(361) Histology results showed that following an examination of sections of liver and kidney from all study animals, no signs of hepatic or renal organ damage were observed.

(362) Following 7 days of PO dosing, mouse weights did not change and histology results for all treated mice indicate that there was no signs of organ toxicity at the doses used (5 and 10 concentrations used in earlier efficacy studies).

(363) Plasma samples collected at the time of study termination indicate that following repeated dosing, the compound is almost completely cleared within 24 hours. However there is a slightly higher level of the compound remaining in the plasma in the higher dose at the conclusion of the study (see FIG. 26A).
