BACKGROUND OF THE INVENTION
• Chromatin is a complex combination of DNA and protein that makes up chromosomes. It is found inside the nuclei of eukaryotic cells and is divided between heterochromatin (condensed) and euchromatin (extended) forms. The major components of chromatin are DNA and proteins. Histones are the chief protein components of chromatin, acting as spools around which DNA winds. The functions of chromatin are to package DNA into a smaller volume to fit in the cell, to strengthen the DNA to allow mitosis and meiosis, and to serve as a mechanism to control expression and DNA replication. The chromatin structure is controlled by a series of post-translational modifications to histone proteins, notably histones H3 and H4, and most commonly within the “histone tails” which extend beyond the core nucleosome structure. Histone tails tend to be free for protein-protein interaction and are also the portion of the histone most prone to post-translational modification. These modifications include acetylation, methylation, phosphorylation, ubiquitinylation, and SUMOylation. These epigenetic marks are written and erased by specific enzymes that place the tags on specific residues within the histone tail, thereby forming an epigenetic code, which is then interpreted by the cell to allow gene specific regulation of chromatin structure and thereby transcription.
• Of all classes of proteins, histones are amongst the most susceptible to post-translational modification. Histone modifications are dynamic, as they can be added or removed in response to specific stimuli, and these modifications direct both structural changes to chromatin and alterations in gene transcription. Distinct classes of enzymes, namely histone acetyltransferases (HATs) and histone deacetylases (HDACs), acetylate or de-acetylate specific histone lysine residues (Struhl K., Genes Dev., 1989, 12, 5, 599-606).
• Bromodomains, which are approximately 110 amino acids long, are found in a large number of chromatin-associated proteins and have been identified in approximately 70 human proteins, often adjacent to other protein motifs (Jeanmougin F., et al., Trends Biochem. Sci., 1997, 22, 5, 151-153; and Tamkun J. W., et al., Cell, 1992, 7, 3, 561-572). Interactions between bromodomains and modified histones may be an important mechanism underlying chromatin structural changes and gene regulation. Bromodomain-containing proteins have been implicated in disease processes including cancer, inflammation and viral replication. See, e.g., Prinjha et al., Trends Pharm. Sci., 33(3):146-153 (2012) and Muller et al., Expert Rev., 13(29): 1-20 (September 2011).
• Cell-type specificity and proper tissue functionality requires the tight control of distinct transcriptional programs that are intimately influenced by their environment. Alterations to this transcriptional homeostasis are directly associated with numerous disease states, most notably cancer, immuno-inflammation, neurological disorders, and metabolic diseases. Bromodomains reside within key chromatin modifying complexes that serve to control distinctive disease-associated transcriptional pathways. This is highlighted by the observation that mutations in bromodomain-containing proteins are linked to cancer, as well as immune and neurologic dysfunction. Hence, the selective inhibition of bromodomains across a specific family, such as the selective inhibition of a bromodomain of CBP/EP300, creates varied opportunities as novel therapeutic agents in human dysfunction.
• There is a need for treatments for cancer, immunological disorders, and other CBP/EP300 bromodomain related diseases.

• In order to prolong the effect of a compound of formula (I) or formula (II), it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues.

In certain embodiments, pharmaceutically acceptable compositions of this invention are administered with food.
• Specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, the judgment of the treating physician, and the severity of the particular disease being treated. The amount of a provided compound of formula I or formula II or salt thereof in the composition will also depend upon the particular compound in the composition.
• In one embodiment, the therapeutically effective amount of the compound of the invention administered parenterally per dose will be in the range of about 0.01-100 mg/kg, alternatively about 0.1 to 20 mg/kg of patient body weight per day, with the typical initial range of compound used being 0.3 to 15 mg/kg/day. In another embodiment, oral unit dosage forms, such as tablets and capsules, contain from about 5 to about 100 mg of the compound of the invention.
• An example tablet oral dosage form comprises about 2 mg, 5 mg, 25 mg, 50 mg, 100 mg, 250 mg or 500 mg of a compound of formula (I) or formula (II) or salt thereof, and further comprises about 5-30 mg anhydrous lactose, about 5-40 mg sodium croscarmellose, about 5-30 mg polyvinylpyrrolidone (PVP) K30 and about 1-10 mg magnesium stearate. The process of formulating the tablet comprises mixing the powdered ingredients together and further mixing with a solution of the PVP. The resulting composition can be dried, granulated, mixed with the magnesium stearate and compressed to tablet form using conventional equipment. An example of an aerosol formulation can be prepared by dissolving about 2-500 mg of a compound of formula I or formula II or salt thereof, in a suitable buffer solution, e.g. a phosphate buffer, and adding a tonicifier, e.g. a salt such sodium chloride, if desired. The solution may be filtered, e.g. using a 0.2 micron filter, to remove impurities and contaminants.

In some embodiments, the CBP/EP300 bromodomain inhibitor does not affect association of other domains of CBP and/or EP300 to chromatin. In some embodiments, CBP/EP300 bromodomain inhibitor binds to the CBP and/or EP300 primarily (e.g., solely) through contacts and/or interactions with the CBP bromodomain and/or EP300 bromodomain. In some embodiments, CBP/EP300 bromodomain inhibitor binds to the CBP and/or EP300 through contacts and/or interactions with the CBP bromodomain and/or EP300 bromodomain as well as additional CBP and/or EP300 residues and/or domains. Methods of assaying association with chromatin are known in the art and include, but are not limited to, chromatin fractionation, BRET assay (Promega), FRAP assay, Chromatin Immunoprecipitation (ChIP), biophysical binding assay, and/or Histone Association Assay. See, e.g., Das et al., BioTechniques 37:961-969 (2004).
• In some embodiments, the CBP/EP300 bromodomain inhibitor does not affect effector function in CD8 cells (i.e., effector function is substantially the same in the presence and/or absence of the CBP/EP300 bromodomain inhibitor). In some embodiments, the CBP/EP300 bromodomain inhibitor does not affect expression levels of perforin, granzyme, and/or EOMES (i.e., expression levels of one or more perforin, granzyme, and/or EOMES are substantially the same in the presence and/or absence of the CBP/EP300 bromodomain inhibitor). In some embodiments, the CBP/EP300 bromodomain inhibitor does not affect expression levels of effector cytokines IFN-γ and/or TNFα (i.e., expression levels of effector cytokines IFN-γ and/or TNFα are substantially the same in the presence and/or absence of the CBP/EP300 bromodomain inhibitor). In some embodiments, the CBP/EP300 bromodomain inhibitor enhances naïve T cell responsiveness to CD3/CD28 stimulation in the presence of Treg cells.
• In some embodiments, the CBP/EP300 bromodomain inhibitor does not substantially bind to (e.g., does not bind to) the HAT domain of CBP and/or EP300. In some embodiments, the CBP/EP300 bromodomain inhibitor does not substantially bind to (e.g., does not bind to) the HAT domain of CBP and/or EP300 as identified in Delvecchio et al., Nat. Struct. & Mol. Biol. 20:1040-1046 (2013), which is incorporated by reference in its entirety. In some embodiments, the CBP/EP300 bromodomain inhibitor does not substantially bind to one or more residues of the amino acid sequence ENKFSAKRLQTTR LGNHLEDRVNKFLRRQNHPEAGEVFVRVVASSDKTVEVKPGMKSRFVDSGEMSESFPY RTKALFAFEEIDGVDVCFFGMHVQEYGSDCPPPNTRRVYISYLDSIHFFRPRCLRTAVYH EILIGYLEYVKKLGYVTGHIWACPPSEGDDYIFHCHPPDQKIPKPKRLQEWYKKMLDKA FAERIIHDYKDIFKQATEDRLTSAKELPYFEGDFWPNVLEESIKELEQEEEERKKEESTAA SETTEGSQGDSKNAKKKNNKKTNKNKSSISRANKKKPSMPNVSNDLSQKLYATMEKH KEVFFVIHLHAGPVINTLPPIVDPDPLLSCDLMDGRDAFLTLARDKHWEFSSLRRSKWST LCMLVELHTQGQD (amino acid residues 1321-1701 of UniProt No. Q92793 (SEQ ID NO: 1)).

In some embodiments, the CBP/EP300 bromodomain inhibitor does not inhibit the histone acetyltransferase (HAT) catalytic activity of CBP and/or EP300.
• Compounds that are CBP/EP300 bromodomain inhibitors are expected to have improved and/or distinct properties over other compounds, such as “HAT” inhibitor compounds. HAT inhibition is expected to result in a global reduction in protein acetylation (histone and non-histone), likely affecting cell viability in a significant way. In some embodiments, CBP/EP300 bromodomain inhibition preserves the HAT activity of these proteins while resulting in the reduction of transcriptional activity of a relatively small subset of target genes.
• In some embodiments, provided are methods of enhancing immune function in an individual having cancer comprising administering an effective amount of any CBP/EP300 bromodomain inhibitors disclosed herein. In some embodiments of any of the methods, the CD8 T cells in the individual have enhanced priming, activation, proliferation, and/or cytolytic activity relative to prior to the administration of the CBP/EP300 bromodomain inhibitor. In some embodiments, the number of CD8 T cells is elevated relative to prior to administration of the CBP/EP300 bromodomain inhibitors.

• In some embodiments, the methods provided herein are useful in treating conditions where enhanced immunogenicity is desired such as increasing tumor immunogenicity for the treatment of cancer. For example, provided herein are CBP/EP300 bromodomain inhibitors for use to enhance T-cell function to upregulate cell-mediated immune responses and for the treatment of T cell dysfunctional disorders, tumor immunity. In some embodiments, the CBP/EP300 bromodomain inhibitors promote anti-tumor immunity by inhibiting the suppressive function of regulatory T (Treg) cells and/or relieving T cell exhaustion on chronically stimulated CD8⁺ T cells. CBP/EP300 bromodomain inhibitors are further useful in reducing FOXP3 expression during extra-thymic Treg cell differentiation. Continual FOXP3 expression is essential to maintain suppressive activity in Treg cells. In some embodiments, reduced FOXP3 expression through CBP/EP300 bromodomain inhibition impairs Treg cells suppressive activity and promotes tumor antiimmunity. Treg cells are highly enriched in tumors derived from multiple cancer indications, including melanoma, NSCLC, renal, overian, colon, pancreatic, hepatocellular, and breast cancer. In a subset of these indications, increased intratumoral Treg cell densities are associated with poor patient prognosis. These indications include NSCLC, ovarian, pancreatic, hepatocellular, and breast cancer. CBP/EP300 bromodomain inhibitors are predicted to impair intratumoral Treg cell function in these cancer indications to enhance effector T cell activity. In other embodiments, the CBP/EP300 bromodomain inhibitors may be used to treat infectious diseases, where some pathogens may have evolved to manipulate regulatory T (Treg) cells to immunosuppress the host to ensure survival, such as in retrovial infections (e.g., HIV), mycobacterial infections (e.g., tuberculosis), and parasitic infections (e.g., Leishmania and malaria).
• In some embodiments, the methods provided herein are useful in treating a CBP and/or EP300-mediated disorder involving fibrosis. In some embodiments, the CBP and/or EP300-mediated disorder is a fibrotic disease. Certain fibrotic diseases may include, for example, pulmonary fibrosis, silicosis, cystic fibrosis, renal fibrosis, liver fibrosis, liver cirrhosis, primary sclerosing cholangitis, primary biliary cirrhosis, endomyocardial fibrosis, mediastinal fibrosis, myelofibrosis, retroperitoneal fibrosis, progressive massive fibrosis, nephrogenic systemic fibrosis, Crohn's disease, keloid, myocardial infarction, systemic sclerosis or arthro fibrosis.
• In other embodiments, the CBP and/or EP300-mediated disorder is a fibrotic lung disease. Fibrotic lung diseases may include, for example, idiopathic pulmonary fibrosis, fibrotic interstitial lung disease, interstitial pneumonia, fibrotic variant of non-specific interstitial pneumonia, cystic fibrosis, lung fibrosis, chronic obstructive pulmonary lung disease (COPD), or pulmonary arterial hypertension. In certain embodiments, the fibrotic lung disease is idiopathic pulmonary fibrosis.

Co-Administration of Compounds and Other Agents
• The compounds of formula (I) or formula (II) or salts thereof may be employed alone or in combination with other agents for treatment. For example, the second agent of the pharmaceutical combination formulation or dosing regimen may have complementary activities to the compound of formula (I) or formula (II) such that they do not adversely affect each other. The compounds may be administered together in a unitary pharmaceutical composition or separately. In one embodiment a compound or a pharmaceutically acceptable salt can be co-administered with a cytotoxic agent to treat proliferative diseases and cancer. The term “co-administering” refers to either simultaneous administration, or any manner of separate sequential administration, of a compound of formula (I) or formula (II) or a salt thereof, and a further active pharmaceutical ingredient or ingredients, including cytotoxic agents and radiation treatment. If the administration is not simultaneous, the compounds are administered in a close time proximity to each other. Furthermore, it does not matter if the compounds are administered in the same dosage form, e.g. one compound may be administered topically and another compound may be administered orally.
• Those additional agents may be administered separately from an inventive compound-containing composition, as part of a multiple dosage regimen. Alternatively, those agents may be part of a single dosage form, mixed together with a compound of this invention in a single composition. If administered as part of a multiple dosage regime, the two active agents may be submitted simultaneously, sequentially or within a period of time from one another normally within five hours from one another.
• As used herein, the term “combination,” “combined,” and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a compound of the present invention may be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present invention provides a single unit dosage form comprising a compound of formula I or formula II, an additional therapeutic agent, and a pharmaceutically acceptable carrier, adjuvant, or vehicle.
• The amount of both an inventive compound and additional therapeutic agent (in those compositions which comprise an additional therapeutic agent as described above) that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. In certain embodiments, compositions of this invention are formulated such that a dosage of between 0.01-100 mg/kg body weight/day of an inventive can be administered.
• Typically, any agent that has activity against a disease or condition being treated may be co-administered. Examples of such agents can be found in Cancer Principles and Practice of Oncology by V. T. Devita and S. Hellman (editors), 6^th edition (Feb. 15, 2001), Lippincott Williams & Wilkins Publishers. A person of ordinary skill in the art would be able to discern which combinations of agents would be useful based on the particular characteristics of the drugs and the disease involved.
• In one embodiment, the treatment method includes the co-administration of a compound of formula (I) or formula (II) or a pharmaceutically acceptable salt thereof and at least one cytotoxic agent. The term “cytotoxic agent” as used herein refers to a substance that inhibits or prevents a cellular function and/or causes cell death or destruction. Cytotoxic agents include, but are not limited to, radioactive isotopes (e.g., At²¹¹, I¹³¹, I¹²⁵, Y⁹⁰, Re¹⁸⁶, Re¹⁸⁸, Sm¹⁵³, Bi²¹², P³², Pb²¹² and radioactive isotopes of Lu); chemotherapeutic agents; growth inhibitory agents; enzymes and fragments thereof such as nucleolytic enzymes; and toxins such as small molecule toxins or enzymatically active toxins of bacterial, fungal, plant or animal origin, including fragments and/or variants thereof.

Example 311
• The inhibitory activity of representative compounds of Formula (II) against CBP/EP300 can be evaluated using known methods or using one of the following assay protocols.
IC₅₀ Measurements for Inhibitors Using CBP TR-FRET Binding Assay
• His/Flag epitope tagged CBP was cloned, expressed, and purified to homogeneity. CBP binding and inhibition was assessed by monitoring the engagement of a biotinylated small molecule compound with the target using the TR-FRET assay technology (Perkin-Elmer). Specifically, in a 384 well ProxiPlate CBP (4 nM final) was combined with biotin-ligand (60 nM final) in 50 mM HEPES (pH 7.5), 50 mM NaCl, 1 mM TCEP, 0.01% (w/v) BSA, and 0.008% (w/v) Brij-35 either in the presence of DMSO (final 0.2% DMSO) or compound dilution series in DMSO. After 10 minutes incubation at room temperature, a mixture Eu-W1024 Anti-6×His antibody (Perkin Elmer ADO 110) and SureLight™ Allophycocyanin-Streptavidin (APC-SA, Perkin Elmer CR130-100) were added to a final concentrations of 0.2 nMolar antibody and 50 nMolar APC-SA, respectively. After twenty minutes of equilibration, the plates were read on an Envision instrument and IC₅₀s calculated using a four parameter non-linear curve fit.
IC₅₀ Measurements for Inhibitors Using BRD4 AlphaLisa Binding Assay
• His/Flag epitope tagged BRD4 BD1_42-168 was cloned, expressed, and purified to. BRD4 binding and inhibition was assessed by monitoring the engagement of biotinylated H4-tetraacetyl peptide (New England Peptide, NEP2069-1/13) with the target using the AlphaLisa technology (Perkin-Elmer). Specifically, in a 384 well ProxiPlate BRD4(BD1) (30 nM final) was combined with peptide (200 nM final) in 40 mM HEPES (pH 7.0), 40 mM NaCl, 1 mM DTT, 0.01% (w/v) BSA, and 0.008% (w/v) Brij-35 either in the presence of DMSO (final 1.2% DMSO) or compound dilution series in DMSO. After 20 minutes incubation at room temperature Alpha streptavidin donor beads and AlphaLisa anti-Flag acceptor beads were added to a final concentration of 10 ug/mL each. After three hours equilibration plates were read on an Envision instrument and IC₅₀s calculated using a four parameter non-linear curve fit.
MYC RPL19 QuantiGene Assay in MV-4-11 Cells
• QuantiGene 2.0 Reagent system, Affymetrix: HUMAN MYCN; V-myc myelocytomatosis viral related oncogene, neuroblastoma derived (avian); NM_005378 SA-15008. 10,000 MV-4-11 cells (GNE in-house) were plated in 75 ul complete media: RPMI-1640 (GNE in-house), 10% FBS (Life Technologies, cat. no. 10082), 1% Pen-strep (GNE in-house), in 96 well clear flat bottom plates (Costar, cat. no. 3595). 25 ul compound was added for 4 hours at 37 deg C. in a 1:3 serial dilution 10-point dose response, with a final DMSO concentration=0.2%. The cells were then lysed according to the assay kit's protocol and frozen at −80 deg C. The following day, an appropriate volume of Working Probe Set was prepared by combining the following reagents in the order listed: Nuclease-free water, Lysis Mixture, Blocking Reagent, and 2.0 Probe Set (MYC or RPL19). 20 ul of the working probe set was added into each assay well on the capture plate, and then 80 ul of the lysates were transferred into the assay plates. The capture plate was placed in a 55 deg C. incubator for overnight hybridization (16-20 hours). The following day, wash buffer was prepared according to manufacturer's recommendations. The capture plates were washed with 300 ul per well of 1× wash buffer three times. Then 100 ul Pre-Amplifier was added to the plate for a 60 minute incubation at 55 deg C. After the incubation, the capture plate was washed with 300 ul per well of 1× wash buffer three times, and 100 ul Amplifier was added to the plate for a 60 minute incubation at 55 deg C. The capture plate was again washed with 300 ul per well of 1× wash buffer three times, and 100 ul Label Probe was added to the plate for a 60 minute incubation at 50 deg C. Then the capture plate was washed with 300 ul per well of 1× wash buffer three times, and 100 ul 2.0 Substrate was added to each well of the plate. The plates were incubated at RT for 5 minutes in the dark and read on the Envision using the luminescence protocol, with an integration time set at 0.2 seconds.

Exemplification of CBP/EP300 Inhibitors for the Treatment of Fibrotic Disease
• The results of the fibrosis experiments described herein are shown in FIGS. 1-14.
• Cell Culture:
• Collagen 1-coated 384-well plates (BD Biosciences cat #356667) were seeded with Normal Human Lung Fibroblasts (Lonza cat #CC-2512) at 2000 cells per well in 50 μl DMEM (Genentech) containing 0.5% fetal bovine serum (Sigma cat #F2442). After 16 hours, the indicated compounds were added to cells at final concentrations ranging from 10 μM to 0.005 nM in an 8-fold dilution series. After one hour, TGF beta (Genentech) was added to cells to a final concentration of 10 ng/ml. All treatments were performed in duplicate.
• Animal Study:
• Bleomycin was administered to mice via subcutaneous implantation of an osmotic pump (Alzet cat #1007D). After bleomycin administration, mice were treated with compounds by oral gavage. Mice received either MCT vehicle (0.5% w/v methylcellulose, 0.2% w/v polysorbate 80), G0272 in MCT at 5 mg/kg twice daily, G0272 in MCT at 15 mg/kg twice daily, G5049 in MCT at 5 mg/kg twice daily, G5049 in MCT at 15 mg/kg twice daily, G3486 in MCT at 15 mg/kg twice daily, or G3486 in MCT at 45 mg/kg twice daily. To label newly synthesized collagen, mice were injected intraperitoneally with 35 ml/kg heavy water (Sigma Aldrich, cat #151882) in two doses and heavy water was provided in drinking water. At study termination, blood samples were collected by retro-orbital bleed under isoflurane anesthesia and mice were euthanized. Upper right lung lobes were placed in glass vials and snap frozen in liquid nitrogen for mass spectrometry. The lower right lung lobe was placed in RNA later for expression analysis, and frozen at −20° C.
• Lung Hydroxyproline Determination:
• Lungs were thawed, dried overnight at 80° C., then hydrolyzed at 110° C. overnight in 6N HCl. The remainder of this paragraph was performed by KineMed, Emeryville Calif.). A 100 μl aliquot of tissue hydrolysate received a spike containing 1 μg ²H3-labeled hydroxyproline (D3-OHP; trans-4-Hydroxy-L-proline-2,5,5-d3; CDN), and then dried under vacuum and re-suspended in a solution of 50% acetonitrile, 50 mM K₂HPO₄ and pentafluorobenzyl bromide before incubation. Derivatives were extracted into ethyl acetate, and the top layer was removed and dried by vacuum centrifugation. In order to acetylate the hydroxyl moiety of hydroxyproline, samples were incubated with a solution of acetonitrile, N-Methyl-N-[tert-butyldimethyl-silyl]trifluoroacetamide and methylimidizole. This material was extracted in petroleum ether and dried with Na₂SO₄. The derivatized hydroxyproline was analyzed by GC/MS, performed in the negative chemical ionization mode. Selected ion monitoring was performed on ions with mass-to-charge ratios (m/z) 445, 446, 447, and 448 which include all of the carbon-hydrogen bonds from hydroxyproline. Incorporation of ²H into hydroxyproline was calculated as the molar fraction of molecules with one excess mass unit above the natural abundance fraction (EM1). Fractional collagen synthesis (f) was calculated as the ratio of the EM1 value in protein-bound hydroxyproline to the maximal value possible at the body water enrichment present. This method has previously been described (Gardner, J. L., et al., Measurement of liver collagen synthesis by heavy water labeling: effects of profibrotic toxicants and antifibrotic interventions. Am J Physiol Gastrointest Liver Physiol, 2007. 292(6): p. G1695-705). Additionally, hydroxyproline content in each tissue sample was determined by comparing the abundance in the m3 448 m/z channel representing the D3-OHP internal standard in each sample with that the m0 445 m/z ion. A set of standards with known OHP/D3-OHP concentration ratios was analyzed alongside the samples. ²H₂O enrichment in plasma was determined using a previously described method (Previs S F, Hazey J W, Diraison F, Beylot M, David F, Brunengraber H (1996) Assay of the deuterium enrichment of water via acetylene. J Mass Spectrom 31:639-642.). Briefly body water is evaporated from plasma by overnight incubation at 80° C. Samples are then mixed in 10M NaOH and acetone followed by a second overnight incubation. This material was extracted in hexane and dried with Na₂SO₄ prior to GCMS analysis.
• RNA Isolation:
• For cultured cells, after 24 hours of treatment with TGF beta and CBP/p300 inhibitor, mRNA was isolated with the Turbocapture 384 mRNA kit (Qiagen cat #72271) according to the manufacturers' instructions and eluted with 30 μl elution buffer. For lungs, tissues were thawed, removed from RNA later, homogenized in GentleMACS M tubes (Miltenyi Biotec cat #130-093-236) and RNA extracted with the RNeasy 96 kit (Qiagen cat #74182) according to the manufacturers instructions.
• Expression Analysis:
• First-strand cDNA was synthesized using 14 μl mRNA for cultured cells and 150 ng RNA for lung. The High Capacity cDNA Reverse Transcription Kit (Life Technologies cat #4368814) was used according to the manufacturers protocol. Specific target amplification was performed using 1.25 μl cDNA, Taqman assays (Life Technologies cat #4331182) at a final concentration of 0.2×, and Taqman Preamp Master Mix (Life Technologies cat #4488593) and subsequently diluted according to the protocol for Fluidigm qPCR (Fluidigm Corp). Samples and assays were mixed with loading buffers and loaded onto 192.24 IFCs (Fluidigm cat #100-6266) according to the manufacturers instructions. Reactions were mixed using the IFC controller RX (Fluidigm) then amplified and measured using the Biomark system (Fluidigm). For cultured cells, relative expression of each target gene was determined using the ΔCt method, normalizing to the Ct for HPRT1 using Excel software (Microsoft). To generate heat maps, TGF beta-mediated expression increase for each gene in the presence of CBP/p300 inhibitor was divided by the increase in the absence of CBP/p300 inhibitor using Excel (i.e. (2^{−ΔCt, SMI+TGFb}−2^{−ΔCt, SMI, no TGFb})/(2^{−ΔCt, TGFb}−2^{−ΔCt, no TGFb})). Line graphs of 2^−ΔCt values were generated using Prism software (Graphpad). For lung, relative expression of each target gene was determined using the ΔΔCt method, normalizing to the Ct for GAPDH and the vehicle control group. Heat maps were generated with Excel software (Microsoft).
• While a number of embodiments have been described, these examples may be altered to provide other embodiments that utilize the compounds and methods described herein. Therefore, the scope of this invention is to be defined by the appended claims rather than by the specific embodiments that have been represented by way of example.
