The present disclosure relates to a pharmaceutical composition for treating and/or preventing SWI/SNF complex dysfunction cancer.
SWI/SNF complexes are involved in various cellular processes such as differentiation and growth by mediating ATP dependent chromatin remodeling and regulating gene expression and DNA repair. SWI/SNF complexes are largely classified into three types of complexes with different constituent elements (BAF complex, PBAF complex, and ncBAF complex). Many studies report that a mutation in a gene encoding a constituent element of an SWI/SNF complex is involved in malignant transformation (Non Patent Literature 1). In particular, genetic mutations of SMARCB1/INI1/SNF5/BAF47, SMARCA2/BAF190/BIS/BRM/NCBRS/SNF2/SNF2LA/SNF2L2, SMARCA4/BAF190A/BRG1/CSS4/MRD16/RTPS2/SNF2/SNF2B/SNF2L4/SNF 2LB, ARID1A/B120/BAF250/BAF250a/BM029/C1orf4/CSS2/ELD/MRD14/OSA1/P270/SMARCF1/hELD/hOSA1, ARID1B/6A3-5/BAF250B/BRIGHT/CSS1/DAN15/ELD/OSA1/MRD12/OSA2/P250R/SMARC F2, and SS18/SMARCL1/SSXT/SYT are reported in multiple cancer species (Non Patent Literatures 2, 3, and 4).
For example, malignant rhabdoid tumor is tumor with very poor prognosis which occurs in any part of the body, particularly in the kidney, central nervous system, soft tissue, etc. In almost all cases, loss of function of SMARCB1 is found. As a method of treating malignant rhabdoid tumor, a therapy combining surgery, polypharmaceutic chemotherapy, and radiation therapy is administered, but the therapeutic outcome thereof is not sufficient. An effective therapeutic method has yet to be established. A certain number of instances of loss of function (suppression of function) of SMARCA2, SMARCA4, or SMARCA2/A4 is found in various cancers including pulmonary adenocarcinoma, a certain number of instances of loss of function (suppression of function) of ARID1A, ARID1B, or ARID1A/1B is found in ovarian cancer and colon cancer, and a certain number of instances of fusion of SS18 and SSX is found in synovial sarcoma and Ewing's sarcoma. Meanwhile, an effective therapeutic method for cancer associated with dysfunction of these agents have yet to be established.
If a function of a gene is lost, survival of a cell would be dependent on the function of another specific gene. A phenomenon where a cell dies when the function of this gene is inhibited is known as “synthetic lethality”. Cancer therapeutic method utilizing “synthetic lethality” (synthetic lethality therapeutic method) is expected as a novel approach to cancer therapeutic method (Non Patent Literature 5).
Histone acetyltransferase CBP/CREBBP and P300/EP300 acetylate a histone protein, resulting in chromatin to be in an open state and promoting expression of a proximal gene (Non Patent Literature 6). While it was known that inhibition of CBP and P300 suppresses proliferative activity of cells (Non Patent Literature 7), there was no disclosure or suggestion that this would be useful as a synthetic lethality therapeutic method for SWI/SNF complex dysfunction cancer.
The present disclosure provides a pharmaceutical composition for treating and/or preventing SWI/SNF complex dysfunction cancer, comprising a CBP/P300 inhibitor.
As a result of diligent studies, the inventors have discovered that a combination of “CBP/P300 inhibition” and “SWI/SNF complex dysfunction” exhibits synthetic lethality. Specifically, it was discovered that a CBP/P300 inhibitor exhibits a significant effect of suppressing growth on SMARCB1 deficient cancer including malignant rhabdoid tumor. It was discovered that a CBP/P300 inhibitor also exhibits a significant effect of suppressing growth of SMARCA2/A4 deficient cancer and SMARCA4 deficient cancer including pulmonary adenocarcinoma. Furthermore, it was discovered that a CBP/P300 inhibitor exhibits a significant effect of suppressing growth of ARID1A/1B deficient cancer and ARID1A deficient cancer including ovarian cancer and SS18-SSX fusion cancer including synovial sarcoma.
More specifically, the inventors discovered that growth of cancer cells was suppressed significantly when a HAT inhibitor that inhibits a HAT domain or a BRD inhibitor that inhibits a BRD domain, which can inhibit the function of CBP/P300, was applied to SMARCB1 deficient cancer cells including malignant rhabdoid tumor, SMARCA2/A4 deficient cancer cells including pulmonary adenocarcinoma, ARID1A/1B or ARID1A deficient cancer cells including ovarian cancer, and cancer cells accompanied by SS18-SSX fusion including synovial sarcoma. The inventors also discovered that growth of cancer cells was suppressed significantly when a HAT inhibitor that inhibits a HAT domain, which can inhibit the function of CBP/P300, was applied to SMARCA4 deficient cancer cells. Furthermore, growth of the cancer cells was suppressed significantly when expression of CBP/P300 was selectively suppressed using siRNA. These results revealed that a combination of CBP/P300 and SWI/SNF complex exhibits synthetic lethality.

The present disclosure is described in more detail hereinafter. Throughout the entire specification, a singular expression should be understood as encompassing the concept thereof in the plural form, unless specifically noted otherwise. Thus, singular articles (e.g., “a”, “an”, “the”, and the like in case of English) should also be understood as encompassing the concept thereof in the plural form, unless specifically noted otherwise. The terms used herein should be understood as being used in the meaning that is commonly used in the art, unless specifically noted otherwise. Therefore, unless defined otherwise, all terminologies and scientific technical terms that are used herein have the same meaning as the general understanding of those skilled in the art to which the present disclosure pertains. In case of a contradiction, the present specification (including the definitions) takes precedence.
“CBP” and “P300” herein are both histone acetyltransferases involved in the regulation of chromatin and are paralogs in relation to each other. Histone acetyltransferase is mainly, but not solely, an enzyme which transfers an acetyl group to a lysine residue that is present on the amino terminal tail of a histone protein. CBP and P300 mainly, but not solely, acetylate histone H2A, H2B, H3, or H4. In particular, histone H3 mainly, but not solely, acetylates lysine 18, lysine 27, lysine 56, and lysine 122 (H3K18, H3K27, H3K56, and H3K122, respectively) residues. In particular, acetylation of histone H3K27 is known as a marker for an open chromatin, and serves a critical role in the regulation of gene expression (J Hum Genet. 2013 July; 58(7): 439-45). p53 (Cell. 1997 August; 90(4): 595-606), MyoD (J Biol Chem. 2000 November; 275(44): 34359-34364), STAT3 (Science. 2005 January; 307 (5707): 269-273), Androgen receptor (J Biol Chem. 2000 July; 275 (27): 20853-20860), etc. have been reported as substrates other than histone. When expressed as “CBP” and “P300” herein, a protein is generally referred, but may refer to a nucleic acid encoding the same or a gene as a concept in accordance with the situation. Those skilled in the art can appropriately understand the term in accordance with the context.
Important functional domains of CBP and P300 include HAT domain, bromo domain (BRD), CH1/CH2/CH3 domain (cysteine-histidine rich domains), KIX domain, etc. (Mol Genet Metab. 2016. 119 (1-2): 37-43). HAT domain is mainly, but not solely, a domain that has activity to transfer an acetyl group to a lysine residue that is present on an amino terminal tail of a histone protein. A bromo domain is mainly, but not solely, a protein domain that recognizes an N-acetylated lysine residue found on an amino terminal tail of a histone protein.
The term “CBP” as used herein refers to any naturally-occurring CBP derived from any vertebrate source including mammals such as primates (e.g., human) and rodents (e.g., mouse and rat), unless specified otherwise. The term encompasses unprocessed CBP and any form of CBP resulting from processing in a cell. The term also encompasses naturally-occurring variants of CBP such as splice variants and allelic variants. Human CBP is registered as UniProt Accession Number: Q92793. Representative amino acid sequences of human CBP are set forth in UniProt Q92793-1 (SEQ ID NO: 1) and UniProt Q92793-2 (SEQ ID NO: 2).

The molecular weight of a “low molecular weight compound” is preferably 5000 or less, more preferably 3000 or less, still more preferably 2000 or less, and most preferably 1000 or less.
“Nucleic acid” refers to a molecule with nucleotides consisting of a base, saccharide, and phosphoric acid connected via a phosphodiester bond. Nucleic acids include ribonucleic acids (RNA) and deoxyribonucleic acids (DNA), including artificially modified or substituted nucleic acids and nucleic acid precursors converted into a nucleic acid in vivo. Examples of artificially modified or substituted nucleic acids include 5-substituted pyrimidine, 6-azapyrimidine, and N-2, N-6, and O-6 substituted purine (including 2-aminopropyladenine), 5-propynyluracil, 5-propynylcytosine, etc. As an artificially modified or substituted nucleic acid, a modified nucleic acid (bridged nucleic acid (BNA)) having position 2′ and position 4′ of the nucleic acid linked (bridged) and having two cyclic structures (bicyclic), etc. can be used. Modified nucleic acids such as a peptide nucleic acid, locked nucleic acid, morpholino nucleic acid, and thio nucleic acid can also be used. Examples of “nucleic acid” include “antisense nucleic acid”, “ribozyme”, and “nucleic acid having RNAi activity”. Preferred examples thereof include antisense nucleic acid, ribozyme, nucleic acid having RNAi activity for a transcriptional product of a gene encoding CBP or P300, and precursors thereof.
Examples of “antisense nucleic acid” include a polydeoxyribonucleotide comprising 2-deoxy-D-ribose, polyribonucleotide comprising D-ribose, other types of polynucleotides which are N-glycoside of a pyrimidine base or purine, other polymers having a non-nucleotide backbone (e.g., commercially available protein nucleic acids and synthetic sequence specific nucleic acid polymers), other polymers comprising a special bond (provided that the polymer comprises a nucleotide with a configuration that allows pairing of bases or attachment of a base as seen in a DNA or RNA), etc. Antisense nucleic acids may be a double stranded DNA, single stranded DNA, double stranded RNA, single stranded RNA, DNA:RNA hybrid, unmodified polynucleotide (or unmodified oligonucleotide), those added with a known modification such as those with a label known in the art, those that are capped, those that are methylated, those with one or more naturally-occurring nucleotides substituted with an analog, those with intramolecular nucleotide modification, such as those with a non-charged bond (e.g., methylphosphonate, phosphotriester, phosphoramidate, carbamate, etc.), those with a charged bond or sulfur containing bond (e.g., phosphorothioate, phosphorodithioate, etc.), such as those having a side chain group of a protein (e.g., nuclease, nuclease inhibitor, toxin, antibody, signal peptide, poly-L-lysine, etc.) or a saccharide (e.g., monosaccharide, etc.), those having an intercalating compound (e.g., acridine, psoralen, etc.), those containing a chelate compound (e.g., metals, radioactive metals, boron, oxidizing metals, etc.), those containing an alkylating agent, or those having a modified bond (for example, α-anomer nucleic acid, etc.). In this regard, “nucleoside”, “nucleotide”, and “nucleic acid” may include not only those containing purine and pyrimidine bases, but also those containing another modified heterocyclic base. Such modified products may contain a methylated purine and pyrimidine, acylated purine and pyrimidine, or other heterocycles. Modified nucleosides and modified nucleotides may also have a modified saccharide moiety, e.g., one or more hydroxyl groups substituted with halogen, aliphatic group, etc., or converted to a functional group such as ether or amine.
As described above, an antisense nucleic acid may be a DNA or RNA, or a DNA:RNA chimera. If an antisense nucleic acid is a DNA, an RNA:DNA hybrid formed by a target RNA and antisense DNA can be recognized by endogenous RNase H and induce selective degradation of the target RNA. Thus, in case of an antisense DNA directing degradation by RNase H, a target sequence may be not only a sequence in an mRNA, but also a sequence of an intron region in an early translation product of a CBP gene or P300 gene. An intron sequence can be determined by comparing the genomic sequence with a cDNA base sequence by using a homology search program such as BLAST or FASTA.
“Ribozyme”, in a narrow sense, refers to an RNA having enzymatic activity for cleaving a nucleic acid, but is used as a concept that also encompasses DNAs herein, as long as it has sequence specific nucleic acid cleaving activity. Ribozymes with highest versatility are self-splicing RNAs seen in infectious RNAs such as viroids and virusoids. Hammerhead ribozymes, hairpin ribozymes, etc. are known. Hammerhead ribozymes exert enzymatic activity with about 40 bases, and can specifically cleave only the target mRNA by having sequences complementary to the desired site of cleavage of mRNA at several bases each (total of about 10 bases) at both ends adjacent to a portion having a hammerhead structure. This type of ribozyme uses only RNA as a substrate and thus has an additional advantage of not attacking genomic DNAs. When an mRNA of a CBP gene or P300 gene itself has a double stranded structure, a target sequence can be a single strand by using a hybrid ribozyme linked to an RNA motif derived from a viral nucleic acid that can specifically bind to an RNA helicase (Proc. Natl. Acad. Sci. USA. 2001; 98(10): 5572-5577). Furthermore, when a ribozyme is used in a form of an expression vector comprising a DNA encoding the same, a hybrid ribozyme further linked to a sequence with an altered tRNA can be prepared to promote migration of a transcriptional product into the cytoplasm (Nucleic Acids Res. 2001; 29(13): 2780-2788).
“Nucleic acid having RNAi activity” refers to a nucleic acid that induces a phenomenon of degrading an mRNA of a target gene when introduced into a cell, known as RNA interference (RNAi). Representative examples include siRNA and shRNA. An siRNA is a double stranded RNA consisting of an oligo RNA complementary to an mRNA of a target gene and a complementary strand thereof. An siRNA can be designed in accordance with rules proposed by, for example, Elbashir et al. (Genes Dev., 2001; 15(2): 188-200) or Teramoto et al. (FEBS Lett. 2005; 579(13): 2878-2882), based on cDNA sequence information of a target gene. The target sequence of an siRNA has a length of, in principle, 15 to 50 bases, and preferably 19 to 27 bases. An siRNA may have an additional base on the 5′ or 3′ terminus. The length of the additional bases is generally about 2 to 4 bases, and the full length of an siRNA is 19 bases or longer. The additional bases may be a DNA or RNA, but the stability of a nucleic acid may be improved when a DNA is used. Examples of the sequence of such additional bases include, but are not limited to, ug-3′, uu-3′, tg-3′, tt-3′, ggg-3′, guuu-3′, gttt-3′, ttttt-3′, uuuuu-3′, etc. An siRNA also may have an overhang on the 3′ terminus. Specific examples thereof include those with an addition of dTdT (dT represents a deoxythimidine residue of a deoxyribonucleic acid). This may also be a blunt end with no addition to a terminus. An siRNA may have different number of bases on the sense strand and antisense strand. Examples thereof include an aiRNA with an antisense strand having an overhand at the 3′ terminus and the 5′ terminus. A typical aiRNA has an antisense strand consisting of 21 bases and a sense strand consisting of 15 bases, with an overhang structure of 3 bases on both ends of the antisense strand (Nat. Biotechnol. 2008; 26(12): 1379-1382, International Publication No. WO 2009/029688). Further, a short hairpin RNA (shRNA) which is a precursor of an siRNA can be designed by selecting any appropriate linker sequence (e.g., about 5 to 25 bases) that can form a loop structure and linking the sense strand and the antisense strand described above via said linker sequence.
A ribonucleoside molecule constituting an siRNA may also be modified in the same manner as the antisense nucleic acid described above in order to improve the stability, specific activity, etc. However for an siRNA, RNAi activity may be lost if all ribonucleoside molecules in a naturally-occurring RNA are replaced with a modified form. Thus, it is necessary to introduce the minimum number of modified nucleosides with which an RISC complex can function. As a specific example of said modification, some of nucleotide molecules constituting an siRNA can be replaced with a naturally-occurring DNA or an RNA subjected to various chemical modifications in order to improve stability (chemical and/or to an enzyme) of specific activity (affinity with RNA) (see Trends Biochem Sci. 1992; 17(9): 334-339). For example, to prevent degradation due to a hydrolase such as nuclease, a phosphoric acid residue (phosphate) of each nucleotide constituting an siRNA can be replaced with, for example, a chemically modified phosphoric acid residue such as phosphorothioate (PS), methylphosphonate, or phosphorodithionate. A hydroxyl group at position 2′ of a saccharide (ribose) of each nucleotide may be substituted with —OR(R═CH3 (2′-O-Me), CH2CH2OCH3 (2′-O-MOE), CH2CH2NHC(NH)NH2, CH2CONHCH3, CH2CH2CN, etc.), or a fluorine atom (—F). Furthermore, a chemical modification may be applied to a base moiety (pyrimidine, purine). Examples thereof include introduction of a methyl group or cationic functional group to position 5 of a pyrimidine base, substitution of a carbonyl group at position 2 to a thiocarbonyl, etc. In addition, the modification method for the antisense nucleic acid described above can be used. Alternatively, a chemical modification that replaces a portion of an RNA in an siRNA with a DNA (2′-deoxy conversion, 2′-H) may be applied. Further, an artificial nucleic acid wherein position 2′ and position 4′ of a saccharide (ribose) are bridged with —O—CH2— to immobilize the conformation to an N-form (LNA, Locked nucleic acid) may be used. Further, a sense strand and antisense strand constituting an siRNA may be chemically attached to, via a linker, a ligand specifically recognizing a receptor that is present on the cell surface layer, peptide, sugar chain, antibody, lipid, positive charge, oligoarginine which molecular structurally adsorbs to and penetrates a cell membrane surface layer, Tat peptide, Rev peptide, Ant peptide, etc.

The cytotoxic activity of a CBP/P300 inhibitor on SMARCB1 deficient cells, i.e., G-401 cells (malignant rhabdoid tumor derived), G-402 cells (malignant rhabdoid tumor derived), and CHLA-06-ATRT cells (atypical teratoid/rhabdoid tumor derived), and SMARCB1 wild-type cells, i.e., 786-O cells (renal cancer derived) was compared.
The G-401 cells, G-402 cells, CHLA-06-ATRT cells, and 786-O cells were obtained from the American Type Culture Collection (ATCC). G-401 cells and G-402 cells were cultured under the conditions of 5% CO2 at 37° C. in a 10% fetal bovine serum and 1% penicillin/streptomycin-containing McCoy's 5A medium. CHLA-06-ATRT cells were cultured under the conditions of 5% CO2 at 37° C. in a 10% B-27 supplement, 20 ng/mL EGF, 20 ng/mL FGF, and 1% penicillin/streptomycin-containing DMEM:F12 medium. 786-0 cells were cultured under the conditions of 5% CO2 at 37° C. in a 10% fetal bovine serum and 1% penicillin/streptomycin-containing RPMI-1640 medium.
A 384-well plate was seeded at 500 cells per well. After one day from seeding, compounds 1 to 19 (Table 47) were added so that the final concentration of DMSO would be 0.1%, and the cells were cultured for 3 days. After completion of culture, the cell survival rate was measured using CellTiter-Glo Luminescent Cell Viability Assay (Promega, G7570). The IC50 value corresponding to the concentration of evaluated compounds at which a cell growth suppression ratio of 50% is exhibited was calculated from a cell survival curve. The results are shown in Table 48. Tests in which the cell survival rate was higher than 50% at 10 μM that is the maximum treatment concentration of each compound are indicated with an IC50 value of “>10 μM”, and the cell survival rate (%) at treatment with 10 μM is indicated within the parenthesis. The compounds subjected to this experiment are shown in Table 21.
As shown in Table 48, GBP/P300 inhibitors, i.e., compounds 1, 3, 4, 5, 6, 9, 10, 14, 15, 16, 17, 18, and 19 exhibited a selective and potent Cell growth suppression effect on SMARCB1 deficient cells, i.e., G-401 cells, G-402 cells, and CHLA-06-ATRT cells. Meanwhile, a cell growth suppression effect was hardly exhibited on human renal cancer cell line and SMARCB1 expressing 786-O cells.
In view of the above, CBP/P300 inhibitors exhibited a selective and potent cell growth suppression effect on SMARCB1 deficient malignant rhabdoid tumor cells and atypical teratoid/rhabdoid tumor cells.
An SMARCB1 overexpressing vector (Precision LentiORF Human SMARCB1 with Stop Codon, Dharmacon, OHS5897-202617080) was introduced into SMARCB1 deficient cells, i.e., JMU-RTK-2 cells (malignant rhabdoid tumor derived), with a lentivirus. After selection with the agent Blasticidine, the cells were cloned to create JMU-RTK-2+SMARCB1 cells (
JMU-RTK-2 cells and JMU-RTK-2+SMARCB1 cells were seeded on a 96-well plate at 500 to 2000 cells/well. After one day from seeding, compounds 1 to 16 were added so that the final concentration of DMSO would be 0.1%, and the cells were cultured for 6 days. After completion of culture, the cell survival rate was measured using CellTiter-Glo Luminescent Cell Viability Assay (Promega, G7570). The IC50 value corresponding to the concentration of evaluated compounds at which a cell growth suppression ratio of 50% is exhibited was calculated from a cell survival curve. The IC50 value of JMU-RTK-2+SMARCB1 cells with respect to the IC50 value of JMU-RTK-2 cells was calculated as a Selective Index for SMARCB1 deficient cells. The results are shown in Table 49.
As shown in Table 49, CBP/P300 inhibitors, i.e., compounds 1 to 16, exhibited a selective and potent cell growth suppression effect on SMARCB1 deficient JMU-RTK-2 cells. Selective Index, which is the ratio of the cell growth suppression effects of SMARCB1 expressing cells and SMARCB1 deficient cells, exhibited a value of 1 or greater.
This demonstrated that CBP/P300 inhibitors have a selective cell growth suppression effect on SMARCB1 deficient malignant rhabdoid tumor cells.
Cytotoxic activity of a CBP/P300 inhibitor on SMARCB1 deficient cells, i.e., G-401 cells (malignant rhabdoid tumor derived), G-402 cells (malignant rhabdoid tumor derived), JMU-RTK-2 cells (malignant rhabdoid tumor derived), and HS-EU-1 cells (epithelioid sarcoma derived), and SMARCB1 wild-type cells, i.e., 786-O cells (renal cancer derived), VMRC-RCZ cells (renal cancer derived), Caki-1 cells (renal cancer derived), H446 cells (lung cancer derived), ES2 cells (ovarian cancer derived), H460 cells (lung cancer derived), H2228 cells (lung cancer derived), HEK293T cells (normal kidney tissue derived), and H358 cells (lung cancer derived) was compared.
G-402 cells, JMU-RTK-2 cells, and HS-ES-1 cells, 786-0 cells, VMRC-RCZ cells, and Caki-1 cells were seeded on a 96-well plate at 500 to 2000 cells per well. After one day from seeding, SGC-CBP30, which is a compound known as a BRD inhibitor, was added so that the final concentration of DMSO would be 0.1%, and the cells were cultured for 6 days. G-401 cells, G-402 cells, JMU-RTK-2 cells and HS-ES-1 cells, and H446 cells, ES2 cells, H460 cells, H2228 cells, HEK293T cells, VMRC-RCZ cells, and H358 cells were also seeded on a 96-well plate at 500 to 2000 cells per well. After one day from seeding, compound 16 was added so that the final concentration of DMSO would be 0.1%, and the cells were cultured for 6 days. After completion of culture, the cell survival rate was measured using CellTiter-Glo Luminescent Cell Viability Assay (Promega, G7570). The IC50 value corresponding to the concentration of evaluated compounds at which a cell growth suppression ratio of 50% is exhibited was calculated from a cell survival curve. The IC50 value of the SMARCB1 deficient cell group was compared with the IC50 value of the SMARCB1 wild-type cell group (

100000 cells were seeded on a 24-well plate per well, and 50 nM of siRNA and Lipofectamine RNAiMAX Transfection Reagent (ThermoFisher, 13778030) was added. After one day, the culture medium was exchanged. After another day, cells were subcultured, and 50 nM of siRNA and Lipofectamine RNAiMAX Transfection Reagent were added again. After another day, the culture medium was exchanged. RNA was extracted from the cells. cDNA was prepared using a reverse transcriptase. The amount of expression of CREBBP and/or EP300 was checked by quantitative PCR (

SensoLyte HAT (p300) Assay Kit (ANASPEC, AS-72172) was used to assess the HAT activity inhibiting capability of a HAT inhibitor. Specifically, 10 μL of compounds 1 to 6 and 14 to 19 diluted with an assay buffer was added to 10 μL of a recombinant p300 solution diluted 10-fold with an assay buffer, and the solution was incubated for 10 minutes at room temperature. 10 μL of acetyl-CoA solution diluted 10-fold with an assay buffer and 20 μL of histone H3 peptide diluted 10-fold with an assay buffer were added thereto, and the mixture was incubated for 30 minutes at 37° C. 50 μL of Stop Solution was added to quench the reaction. 100 μL of p300 Developer solution diluted 50-fold with an assay buffer was added, and the mixture was incubated for 30 minutes at room temperature under shaded conditions. 513 nm fluorescence when irradiated with 389 nm excitation light was measured using a multiplate reader. The IC50 value corresponding to the concentration of a compound at which 50% oxygen reaction inhibition ratio is exhibited was calculated based on the measured fluorescence intensity. The results are shown in Table 50.
As shown in Table 50, compounds 1 to 6 and 14 to 19 were confirmed to inhibit the function of HAT.
BRD function inhibiting capacity of a BRD inhibitor was evaluated by using a CBP bromodomain TR-FRET Assay Kit (Cayman, 600850).

The IC50 value corresponding to the concentration of a compound at which 50% BRD function inhibition ratio is exhibited was calculated based on the measured fluorescence intensity. The results are shown in Table 51. Tests in which the BRD function inhibition ratio was 50% or greater at 0.025 μM that is the minimum treatment concentration of each compound are indicated with an IC50 value of “<0.025 μM”, and the BRD function inhibition ratio (%) at treatment with 0.025 μM is indicated within the parenthesis.

After one day from seeding, compounds 1 to 16 or BRD inhibitor SGC-CBP30 (denoted as “SGC” in the figures) were added so that the final concentration of DMSO would be 0.1%, and the cells were cultured for 24 hours. After completion of culture, the cells were detached through trypsin treatment. The culture was centrifuged and the supernatant was removed to recover cell pellets. 150 μL of RIPA buffer was added to the cell pellets to lyse the cells to extract the entire protein. Acetylation of histone H3K27 was detected by Western blotting. An anti-acetylation H3K27 antibody (Cell Signaling Technology, 8173) was used for the detection of acetylated H3K27 (
