Epigenetic regulation of gene expression is an important biological determinant of protein production and cellular differentiation and plays a significant pathogenic role in a number of human diseases.
Epigenetic regulation involves heritable modification of genetic material without changing its nucleotide sequence. Typically, epigenetic regulation is mediated by selective and reversible modification (e.g., methylation) of DNA and proteins (e.g., histones) that control the conformational transition between transcriptionally active and inactive states of chromatin. These covalent modifications can be controlled by enzymes such as methyltransferases (e.g., CARM1 (co-activator-associated arginine methyltransferase 1; PRMT4)), many of which are associated with specific genetic alterations that can cause human disease.
Disease-associated chromatin-modifying enzymes play a role in diseases such as proliferative disorders, autoimmune disorders, muscular disorders, and neurological disorders. Thus, there is a need for the development of small molecules that are capable of inhibiting the activity of CARM1.
CARM1 is an attractive target for modulation given its role in the regulation of diverse biological processes. It has now been found that compounds described herein, and pharmaceutically acceptable salts and compositions thereof, are effective as inhibitors of CARM1. Such compounds have the general Formula (I):

Pharmaceutical compositions are further provided comprising a compound described herein (e.g., a compound of Formula (I), or a pharmaceutically acceptable salt thereof) and, optionally, a pharmaceutically acceptable excipient.
In certain embodiments, compounds described herein inhibit the activity of CARM1. In certain embodiments, methods of inhibiting CARM1 are provided which comprise contacting CARM1 with an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof. The CARM1 may be purified or crude, and may be present in a cell, tissue, or a subject. Thus, such methods encompass inhibition of CARM1 activity both in vitro and in vivo.

In certain embodiments, the CARM1 is in an animal, e.g., a human. In some embodiments, the CARM1 is expressed at normal levels in a subject, but the subject would benefit from CARM1 inhibition (e.g., because the subject has one or more mutations in an CARM1 substrate that causes an increase in methylation of the substrate with normal levels of CARM1). In some embodiments, the CARM1 is in a subject known or identified as having abnormal CARM1 activity (e.g., overexpression). In some embodiments, the CARM1 is in a subject known or identified as having aberrant CARM1 activity. In some embodiments, a provided compound is selective for CARM1 over other methyltransferases.

Compounds and compositions described herein are generally useful for the inhibition of CARM1. In some embodiments, the CARM1 is human CARM1. In some embodiments, methods of treating CARM1-mediated disorder in a subject are provided which comprise administering an effective amount of a compound described herein (e.g., a compound of Formula (I), or a pharmaceutically acceptable salt thereof), to a subject in need of treatment. In certain embodiments, the effective amount is a therapeutically effective amount. In certain embodiments, the effective amount is a prophylactically effective amount. In certain embodiments, the subject is suffering from a CARM1-mediated disorder. In certain embodiments, the subject is susceptible to a CARM1-mediated disorder.
As used herein, the term “CARM1-mediated disorder” means any disease, disorder, or other pathological condition in which CARM1 is known to play a role. Accordingly, in some embodiments, the present disclosure relates to treating or lessening the severity of one or more diseases in which CARM1 is known to play a role.
In some embodiments, the present disclosure provides a method of inhibiting CARM1 comprising contacting CARM1 with an effective amount of a compound described herein, e.g., a compound of Formula (I), or a pharmaceutically acceptable salt thereof. The CARM1 may be purified or crude, and may be present in a cell, tissue, or subject. Thus, such methods encompass both inhibition of in vitro and in vivo CARM1 activity. In certain embodiments, the method is an in vitro method, e.g., such as an assay method. It will be understood by one of ordinary skill in the art that inhibition of CARM1 does not necessarily require that all of the CARM1 be occupied by an inhibitor at once. Exemplary levels of inhibition of CARM1 include at least 10% inhibition, about 10% to about 25% inhibition, about 25% to about 50% inhibition, about 50% to about 75% inhibition, at least 50% inhibition, at least 75% inhibition, about 80% inhibition, about 90% inhibition, and greater than 90% inhibition.
In some embodiments, provided is a method of inhibiting CARM1 activity in a subject in need thereof comprising administering to the subject an effective amount of a compound described herein (e.g., a compound of Formula (I), or a pharmaceutically acceptable salt thereof, or a pharmaceutical composition thereof.
In certain embodiments, provided is a method of modulating gene expression or activity in a cell which comprises contacting a cell with an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof. In certain embodiments, the cell in culture in vitro. In certain embodiments, the cell is in an animal, e.g., a human. In certain embodiments, the cell is in a subject in need of treatment.
In certain embodiments, provided is a method of modulating transcription in a cell which comprises contacting a cell with an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof. In certain embodiments, the cell in culture in vitro. In certain embodiments, the cell is in an animal, e.g., a human. In certain embodiments, the cell is in a subject in need of treatment.
In certain embodiments, a method is provided of selecting a therapy for a subject having a disease associated with CARM1-mediated disorder or mutation comprising the steps of determining the presence of CARM1-mediated disorder or gene mutation in the CARM1 gene or and selecting, based on the presence of CARM1-mediated disorder a gene mutation in the CARM1 gene a therapy that includes the administration of a provided compound. In certain embodiments, the disease is cancer.
In certain embodiments, a method of treatment is provided for a subject in need thereof comprising the steps of determining the presence of CARM1-mediated disorder or a gene mutation in the CARM1 gene and treating the subject in need thereof, based on the presence of a CARM1-mediated disorder or gene mutation in the CARM1 gene with a therapy that includes the administration of a provided compound. In certain embodiments, the subject is a cancer patient.
In some embodiments, a compound provided herein is useful in treating a proliferative disorder, such as cancer. For example, while not being bound to any particular mechanism, protein arginine methylation by CARM1 is a modification that has been implicated in signal transduction, gene transcription, DNA repair and mRNA splicing, among others; and overexpression of CARM1 within these pathways is often associated with various cancers. Thus, compounds which inhibit the action of PRMTs, and specifically CARM1, as provided herein, are effective in the treatment of cancer.
In some embodiments, compounds provided herein are effective in treating cancer through the inhibition of CARM1. For example, CARM1 levels have been shown to be elevated in castration-resistant prostate cancer (CRPC) (e.g., see Di Lorenzo et al., Drugs (2010) 70:983-1000), as well as in aggressive breast tumors (Hong et al., Cancer 2004 101, 83-89; El Messaoudi et al., Proc. Natl. Acad. Sci. U.S.A 2006, 103, 13351-13356; Majumder et al., Prostate 2006 66, 1292-1301). Thus, in some embodiments, inhibitors of CARM1, as described herein, are useful in treating cancers associated with aberrant CARM1 activity, e.g., CARM1 overexpression or aberrant protein methylation. For example, aberrant CARM1 activity has been found in prostate cancer (e.g., see Hong et al., Cancer (2004), 101:83-89); plays a coactivator role in the dysragulation of beta-catenin activity in colorectal cancer (e.g., see Ou et al., Mol. Cancer Res. (2011) 9:660); and has been linked to estrogen signaling and estrogen related cancers such as breast cancer (see, e.g., Teyssiewr et al., Trends in Endocrinology and Metabolism (2010) 21:181-189). CARM1 has also been shown to affect estrogen receptor alpha (ER-alpha) dependent breast cancer cell differentiation and proliferation (Al-Dhaheri et al., Cancer Res. 2011 71, 2118-2128), thus in some aspects CARM1 inhibitors, as described herein, are useful in treating ERα-dependent breast cancer by inhibiting cell differentiation and proliferation. In another example, CARM1 has been shown to be recruited to the promoter of E2F1 (which encodes a cell cycle regulator) as a transcriptional co-activator (Frietze et al., Cancer Res. 2008 68, 301-306). Thus, CARM1-mediated upregulation of E2F1 expression may contribute to cancer progression and chemoresistance as increased abundance of E2F1 triggers invasion and metastasis by activating growth receptor signaling pathways, which in turn promote an antiapoptotic tumor environment (Engelmann and Piitzer, Cancer Res 2012 72; 571). Accordingly, in some embodiments, the inhibition of CARM1, e.g., by compounds provided herein, is useful in treating cancers associated with E2F1 upregulation, e.g., such as lung cancer (see, e.g., Eymin et al., Oncogene (2001) 20:1678-1687), and breast cancer (see, e.g., Brietz et al., Cancer Res. (2008) 68:301-306). Thus, without being bound by any particular mechanism, the inhibition of CARM1, e.g., by compounds described herein, is beneficial in the treatment of cancer. CARM1 overexpression has also been demonstrated to be elevated in 75% of colorectal cancers (Kim et al., BMC Cancer, 10, 197). It has been additionally been determined that depletion of CARM1 in WNT/β-catenin dysregulated colorectal cancer suppressed anchorage independent growth (Ou et al., Mol. Cancer. Res., 2011 9, 660-670). This, in some embodiments, the inhibition of CARM1, e.g. by compounds provided herein, is useful in colorectal cancer associated with elevated CARM1 expression or dysregulated WNT/β-catenin signaling.

Recombinant baculovirus were generated according to Bac-to-Bac kit instructions (Life Technologies). Protein over-expression was accomplished by infecting exponentially growing HEK 293F cell culture at 1.3×106 cell/ml with virus (MOI=10) in the presence of 8 mM sodium butyrate. Infections were carried out at 37° C. for 48 hours, harvested by centrifugation, and stored at −80° C. for purification.
Expressed full-length human Flag- and His-tagged CARM1 protein was purified from cell paste by anti-flag M2 affinity chromatography with resin equilibrated with buffer containing 20 mM Tris, 150 mM NaCl, 5% glycerol, pH 7.8. Column was washed with 500 mM NaCl in buffer A and Flag-CARM1-His was eluted with 200 ug/ml FLAG peptide in buffer A. Pooled fractions were dialyzed in 20 mM Tris, 150 mM NaCl, 5% glycerol and 1 mM DTT, pH 7.8. The purity of recovered protein was 94.
The assays were all performed in a buffer consisting of 20 mM Bicine (pH=7.6), 1 mM TCEP, 0.005% BSG, and 0.002% Tween 20, prepared on the day of use. Compounds in 100% DMSO (1 ul) were spotted into a polypropylene 384-well V-bottom plates (Greiner) using a Platemate Plus outfitted with a 384-channel head (Thermo Scientific). DMSO (1 ul) was added to Columns 11, 12, 23, 24, rows A-H for the maximum signal control and 1 ul of SAH, a known product and inhibitor of CARM1, was added to columns 11, 12, 23, 24, rows I-P for the minimum signal control. A cocktail (40 ul) containing the CARM1 enzyme was added by Multidrop Combi (Thermo-Fisher). The compounds were allowed to incubate with CARM1 for 30 min at room temperature, then a cocktail (10 ul) containing 3H-SAM and peptide was added to initiate the reaction (final volume=51 ul). The final concentrations of the components were as follows: CARM1 was 0.25 nM, 3H-SAM was 30 nM, peptide was 250 nM, SAH in the minimum signal control wells was 1 mM, and the DMSO concentration was 2%. The assays were stopped by the addition of non-radiolabeled SAM (10 ul) to a final concentration of 300 uM, which dilutes the 3H-SAM to a level where its incorporation into the peptide substrate is no longer detectable. 50 ul of the reaction in the 384-well polypropylene plate was then transferred to a 384-well Flashplate and the biotinylated peptides were allowed to bind to the streptavidin surface for at least 1 hour before being washed once with 0.1% Tween20 in a Biotek ELx405 plate washer. The plates were then read in a PerkinElmer TopCount plate reader to measure the quantity of 3H-labeled peptide bound to the Flashplate surface, measured as disintegrations per minute (dpm) or alternatively, referred to as counts per minute (cpm).

Calculations.
First, the ratio for each well was determined by:
Each plate included fourteen control wells of DMSO only treatment (minimum inhibition) as well as fourteen control wells for maximum inhibition treated with 20 μM of a reference compound. The average of the ratio values for each control type was calculated and used to determine the percent activation for each test well in the plate. Reference compound was serially diluted three-fold in DMSO for a total of nine test concentrations, beginning at 20 μM.
Percent inhibition was determined and IC50 curves were generated using triplicate wells per concentration of compound.
