Patent Description:
The field of the invention relates to substituted heterocycles as c-MYC targeting agents. In particular, the field of the invention relates to substituted pyrazoles, pyrimidines, or trizoles as c-MYC targeting agents for the treatment of cell proliferation diseases and disorders such as cancer.

The c-MYC oncogene is de-regulated and plays a causal role in a majority of human cancer and c-MYC inhibition profoundly affects tumor growth or survival in multiple models. MYC is the most common oncogene involved in human cancers and is overexpressed in up to half of all cancers. Therefore, developing c-MYC inhibitors is among the most attractive potential anti-cancer strategies. Unfortunately, due to the difficulty in targeting transcription factors with small molecules, c-MYC is currently regarded as "undruggable. " Here, we disclose a new approach to targeting c-MYC and have developed a series of new small molecule inhibitors. These compounds selectively target c-MYC-driven cell proliferation and interfere with binding of c-MYC to DNA.

The present invention is described herein using several definitions, as set forth below and throughout the application.

Unless otherwise specified or indicated by context, the terms "a", "an", and "the" mean "one or more. " For example, "a compound" should be interpreted to mean "one or more compounds.

As used herein, "about," "approximately," "substantially," and "significantly" will be understood by persons of ordinary skill in the art and will vary to some extent on the context in which they are used. If there are uses of these terms which are not clear to persons of ordinary skill in the art given the context in which they are used, "about" and "approximately" will mean plus or minus ≤<NUM>% of the particular term and "substantially" and "significantly" will mean plus or minus ><NUM>% of the particular term.

As used herein, the terms "include" and "including" have the same meaning as the terms "comprise" and "comprising" in that these latter terms are "open" transitional terms that do not limit claims only to the recited elements succeeding these transitional terms. The term "consisting of," while encompassed by the term "comprising," should be interpreted as a "closed" transitional term that limits claims only to the recited elements succeeding this transitional term. The term "consisting essentially of," while encompassed by the term "comprising," should be interpreted as a "partially closed" transitional term which permits additional elements succeeding this transitional term, but only if those additional elements do not materially affect the basic and novel characteristics of the claim.

As used herein, a "subject" may be interchangeable with "patient" or "individual" and means an animal, which may be a human or non-human animal, in need of treatment.

A "subject in need of treatment" may include a subject having a disease, disorder, or condition that is responsive to therapy with a substituted heterocycle such as the presently disclosed substituted pyrazoles, substituted pyrimidines, and substituted triazoles.

A "subject in need of treatment" may include a subject having a cell proliferative disease, disorder, or condition such as cancer that is associated with c-MYC activity and/or that may be treated by administering an effective amount of an agent that modulates c-MYC activity.

As used herein, the phrase "effective amount" shall mean that drug dosage that provides the specific pharmacological response for which the drug is administered in a significant number of subject in need of such treatment. An effective amount of a drug that is administered to a particular subject in a particular instance will not always be effective in treating the conditions/diseases described herein, even though such dosage is deemed to be a therapeutically effective amount by those of skill in the art.

As used herein, the term "modulate" means decreasing or inhibiting activity and/or increasing or augmenting activity. For example, modulating c-MYC activity may mean increasing or augmenting c-MYC activity and/or decreasing or inhibiting c-MYC activity. The compounds disclosed herein may be administered to modulate c-MYC activity.

MYC is the most frequently amplified oncogene in human cancers. It has been extensively validated as essential for tumor initiation and maintenance in numerous tumor histologies. Numerous studies have provided solid evidence that pharmacologic targeting of MYC would directly affect tumor progression. One example is OmoMYC, a dominant-negative peptide of MYC that competitively binds MYC in a manner that prevents MYC-Max heterodimerization. OmoMYC expression prompts rapid growth arrest and down-regulation of MYC target genes in cancer cells both in vitro and in vivo. Small molecule inhibitors of MYC will be the optimal form for drug development. However, disruption of MYC-Max interactions through small molecules has been difficult because there are no obvious binding regions in the interface. Thus far, over <NUM> small molecules have been documented with MYC inhibition activity in vitro, but the evidence for their in vivo activities is lacking, likely due to their poor drug-like properties. Among these compounds, <NUM>-f4 and <NUM>-G5 are well-known for their specificities and relatively clear mechanisms in interrupting MYC-Max binding. However, the in vivo studies were quite disappointing because of their rapid metabolism. Thus, developing new MYC inhibitors with high potency and specificity as well as favorable drug-like properties will be critical to effectively target MYC.

To this end, we carried out an in silico screen to identify compounds that might inhibit the binding of c-MYC to DNA. These compounds were tested in several cell-based assays to identify the most active hits. The best hit, Min-<NUM> (NUCC-<NUM> (reference)) and its related analogs were shown to prevent c-MYC/DNA binding. We then synthesized a series of novel structural analogs and these were tested in the same c-MYC-relevant assays. Our new compounds display excellent potency at inhibiting c-MYC/DNA binding. The compounds we have developed using a novel approach possess greatly improved drug-like properties over existing small molecules such as <NUM>-f4 and therefore represent excellent starting points for developing MYC-targeting therapeutics.

In the absence of a regular small-molecule ligand-binding pocket in the c-MYC/Max/DNA ternary complex, we applied multiple independent in silico approaches to increase our likelihood of successfully identifying new small molecule inhibitors. (See <FIG>). We carried out in-silico screening of a <NUM> million compound drug-like library. We applied two different approaches to screen the ZINC compound database after removing promiscuous and non drug-like compounds using PAINS filters. The first approach is based on a <NUM>-tier docking protocol using a published crystal structure of MYC/Max bound to DNA. After defining a putative ligand-binding site as reported in the literature, the compound library was screened using the docking tool. The second approach was based on building a pharmacophore model considering of <NUM> compounds reported to inhibit MYC and screening the Zinc database against this pharmacophore. We obtained <NUM> hits from the structure-based screen and <NUM> hits from the ligand-based pharmacophore screen, with <NUM> compounds in common between the two approaches.

To test the compounds, we evaluated the in silico hits in a MYC E-Box luciferase reporter assay to measure the effects of these compounds (referred to as Min-<NUM> to Min-<NUM>) on MYC transcriptional activity. As shown in <FIG>, about <NUM> compounds have similar or better activity compared to positive control <NUM>-F4 at <NUM>. (See <FIG>).

We next examined the ability of the compounds to selectively inhibit the proliferation of wild type cells expressing MYC relative to cells with MYC knockout. We tested the top <NUM> active compounds in the first screen assay. <FIG> shows a graph of growth inhibition by each compound on the wild type and MYC knockout rat fibroblasts at the dose with the greatest selectivity. More than half of the tested compounds show better growth inhibitory effect on MYC WT compared to MYC KO cells. Min9-S7 (NUCC-<NUM> (reference)) is very promising because of its low effective concentration (<NUM>) and high specificity. Min9-S9 (NUCC-<NUM> (reference)) also shows a great selectivity at an acceptable dosage (<NUM>).

Min9 (NUCC-<NUM> (reference)) was also tested in a cell viability assay against a cMYC wild-type (WT) and a cMYC KO line. As shown in <FIG>, this compound reduces cell viability much more in the WT line than the KO cells, indicating a mechanism directly related to cMYC.

We also tested our best hit compound Min9 (NUCC-<NUM> (reference)) and newly synthesized analogs for effects of these compounds on MYC/Max binding to DNA in electrophoretic mobility shift assays (EMSAs). (See Figure 5a and Figure 5b). We expected the active compounds to impair MYC/Max binding to DNA. Several strucutural analogs of Min9 were tested over multiple doses for inhibiting MYC-DNA binding and we observed a dose-dependent inhibition. (See Figure 5c).

Min9 (NUCC-<NUM> (reference)) was also tested for its ability to cause DNA damage in an rH2AX staining assay. We would not expect cMYC-targeting agents to produce significant DNA damage. Compounds that act directly against DNA such as doxorubicin do however. We observed essentially no DNA damage caused by Min9 (NUCC-<NUM> (reference)). (See <FIG>).

In vitro metabolism of NUCC-<NUM> (reference) and NUCC-<NUM> (reference) were tested using mouse liver microsomes and a mouse S9 fraction. (See <FIG>). NUCC-<NUM> (reference) was significantly metabolism by the mouse S9 fraction versus NUCC-<NUM> (reference) likely due to S9 conjugation at the N-<NUM> nitrogen atom of the pyrazole ring.

The pharmacokinetics of NUCC-<NUM> (reference) and NUCC-<NUM> (reference) were studied in mice by administering a dose of <NUM>/kg intravenously and measuring the plasma concentration versus time. (See <FIG>). The observed in vivo metabolism of NUCC-<NUM> (reference) and NUCC-<NUM> (reference) correlated well with the observed in vitro metabolism tested above for of NUCC-<NUM> (reference) and NUCC-<NUM> (reference).

General Experimental. All chemical reagents were obtained from commercial suppliers and used without further purification unless otherwise stated. Anhydrous solvents were purchased from Sigma-Aldrich, and dried over <NUM>Å molecular sieves when necessary. DCM and THF were purified by passage through a bed of activated alumina. Normal-phase flash column chromatography was performed using Biotage KP-Sil <NUM> silica gel columns and ACS grade solvents on a Biotage Isolera flash purification system. Analytical thin layer chromatography (TLC) was performed on EM Reagent <NUM> silica gel <NUM> F<NUM> plates and visualized by UV light or iodine vapor. Liquid chromatography/mass spectrometry (LCMS) was performed on a Waters Acquity-H UPLC system with a <NUM> × <NUM>, <NUM>, reversed phase BEH C18 column and LCMS grade solvents. A gradient elution from <NUM>% water + <NUM>% formic acid/<NUM>% acetonitrile + <NUM>% formic acid to <NUM>% acetonitrile + <NUM>% formic acid/ <NUM>% water + <NUM>% formic acid over <NUM> plus a further minute continuing this mixture at a flow rate of <NUM>/min was used as the eluent. Total ion current traces were obtained for electrospray positive and negative ionization (ESI+/ESI-). Proton (<NUM>H) and carbon (<NUM>C) NMR spectra were recorded on a Bruker Avance III w/ direct cryoprobe spectrometer. Chemical shifts were reported in ppm (δ) and were referenced using residual non-deuterated solvent as an internal standard. The chemical shifts for <NUM>H NMR and <NUM>C NMR are reported to the second decimal place. Proton coupling constants are expressed in hertz (Hz). The following abbreviations were used to denote spin multiplicity for proton NMR: s = singlet, d = doublet, t = triplet, q = quartet, m = multiplet, brs = broad singlet, dd = doublet of doublets, dt= doublet of triplets, quin = quintet, tt = triplet of triplets. In some cases, overlapping signals occurred in the <NUM>C NMR spectra.

General Description. As of early <NUM> all compounds submitted to the NCI <NUM> Cell screen are tested initially at a single high dose (<NUM>-<NUM>) in the full NCI <NUM> cell panel. Only compounds which satisfy pre-determined threshold inhibition criteria in a minimum number of cell lines will progress to the full <NUM>-dose assay. The threshold inhibition criteria for progression to the <NUM>-dose screen was selected to efficiently capture compounds with antiproliferative activity based on careful analysis of historical DTP screening data. The threshold criteria may be updated as additional data becomes available.

Interpretation of One-Dose Data. The One-dose data will be reported as a mean graph of the percent growth of treated cells and will be similar in appearance to mean graphs from the <NUM>-dose assay. The number reported for the One-dose assay is growth relative to the no-drug control, and relative to the time zero number of cells. This allows detection of both growth inhibition (values between <NUM> and <NUM>) and lethality (values less than <NUM>). This is the same as for the <NUM>-dose assay, described below. For example, a value of <NUM> means no growth inhibition. A value of <NUM> would mean <NUM>% growth inhibition. A value of <NUM> means no net growth over the course of the experiment. A value of -<NUM> would mean <NUM>% lethality. A value of -<NUM> means all cells are dead. Information from the One-dose mean graph is available for COMPARE analysis.

NCI <NUM> Cell Five-Dose Screen (<FIG>, <FIG>, and <FIG>). Compounds which exhibit significant growth inhibition in the One-Dose Screen are evaluated against the <NUM> cell panel at five concentration levels.

The human tumor cell lines of the cancer screening panel are grown in RPMI <NUM> medium containing <NUM>% fetal bovine serum and <NUM> L-glutamine. For a typical screening experiment, cells are inoculated into <NUM> well microtiter plates in <NUM>µL at plating densities ranging from <NUM>,<NUM> to <NUM>,<NUM> cells/well depending on the doubling time of individual cell lines. After cell inoculation, the microtiter plates are incubated at <NUM>° C, <NUM> % CO2, <NUM> % air and <NUM> % relative humidity for <NUM> prior to addition of experimental drugs.

After <NUM>, two plates of each cell line are fixed in situ with TCA, to represent a measurement of the cell population for each cell line at the time of drug addition (Tz). Experimental drugs are solubilized in dimethyl sulfoxide at <NUM>-fold the desired final maximum test concentration and stored frozen prior to use. At the time of drug addition, an aliquot of frozen concentrate is thawed and diluted to twice the desired final maximum test concentration with complete medium containing <NUM>µg/ml gentamicin. Additional four, <NUM>-fold or ½ log serial dilutions are made to provide a total of five drug concentrations plus control. Aliquots of <NUM>µl of these different drug dilutions are added to the appropriate microtiter wells already containing <NUM>µl of medium, resulting in the required final drug concentrations.

Following drug addition, the plates are incubated for an additional <NUM> at <NUM>, <NUM> % CO2, <NUM> % air, and <NUM> % relative humidity. For adherent cells, the assay is terminated by the addition of cold TCA. Cells are fixed in situ by the gentle addition of <NUM>µl of cold <NUM> % (w/v) TCA (final concentration, <NUM> % TCA) and incubated for <NUM> minutes at <NUM>. The supernatant is discarded, and the plates are washed five times with tap water and air dried. Sulforhodamine B (SRB) solution (<NUM>µl) at <NUM> % (w/v) in <NUM> % acetic acid is added to each well, and plates are incubated for <NUM> minutes at room temperature. After staining, unbound dye is removed by washing five times with <NUM> % acetic acid and the plates are air dried. Bound stain is subsequently solubilized with <NUM> trizma base, and the absorbance is read on an automated plate reader at a wavelength of <NUM>. For suspension cells, the methodology is the same except that the assay is terminated by fixing settled cells at the bottom of the wells by gently adding <NUM>µl of <NUM> % TCA (final concentration, <NUM> % TCA). Using the seven absorbance measurements [time zero, (Tz), control growth, (C), and test growth in the presence of drug at the five concentration levels (Ti)], the percentage growth is calculated at each of the drug concentrations levels. Percentage growth inhibition is calculated as:.
