Enzyme activity test
Alpha screen assay system was used to evaluate the activity of KDM enzyme. The buffers and reagents used for evaluation are shown in Table S1. 2.5 μL of inhibitor solution (3.0% DMSO/assay buffer solution) or assay buffer (50 mM HEPES pH 7.5, 0.1% w/v BSA, 0.01% v/v Tween-20 containing 3% DMSO, for control and blank) was added to each well of the OptiPlate -384 white plate. 5.0 μL of enzyme solution was added there. (5.0 μL assay buffer was added to blank wells). After 5 minutes at room temperature, 2.5 μL of substrate protein/2-OG (50 μM)/Fe(II) (5 μM)/sodium ascorbate (100 μM) buffer solution was added to each well. The final concentrations of enzymes and substrate proteins are summarized in Table S2. These reaction solutions were stirred at room temperature for 1 or 2 hours with gentle shaking (250 rpm). 5.0 μL of an epigenetic buffer solution of acceptor beads (100 μg/mL) was added to each well and gently shaken (250 rpm) at room temperature for 1 hour. Finally, 10 μL of an epigenetic buffer solution (50 μg/mL) of donor beads was added and shaken at room temperature for 30 minutes in the dark (250 rpm). Alpha signals were then detected with Ensight (R) readers (PerkinElmer Ltd). (Excitation wavelength: 615 nm, emission wavelength: 655 nm). Enzyme activity (%) was calculated by dividing the Alpha signal of inhibitor wells by the signal of control wells. The results are shown in FIG.

ウェスタンブロッティング
PC3, LnCAP および MKN45 細胞 (5 x 105cells/2 mL/dish)にNPC-3543 を処理し、48時間培養した。その後細胞ペレットをSDSバッファーで抽出した。抽出したライセートのタンパク質濃度をBCA protein assayを用いて測定した。ライセートのタンパク濃度を揃え、5-20% SDS-polyacrylamideゲルを用いて電気泳動を行った。さらにPVDFメンブレンに転写した。メンブレンを5%スキムミルクTBS-T溶液でブロッキングを行った後、一次抗体polyclonal H3K4me3 antibody (Abcam, #ab8580) (1:5000希釈), H3K4me2 antibody (CST, #9725) (1:5000希釈), H3K4me1 antibody (Abcam, #ab8895) (1:5000希釈), H3 antibody (Abcam, #ab1791) (1:200000 希釈), KDM5A antibody (CST, #3876) (1:1000希釈), KDM5B antibody (CST, #3273) (1:1000希釈)、KDM5C antibody (CST, #5361) (1:1000希釈)、mouse monoclonal α-tubulin antibody (sigma, #T8203) (1:1000希釈)をそれぞれ5%スキムミルクTBS-T溶液で希釈し、室温で1時間振盪撹拌して反応させた。メンブレンを3回TBS-Tで洗浄後、二次抗体ECL rabbit/mouse IgG, HRP-linked whole Anti-body (GE Healthcare Life Sciences, #NA934) (1:2500希釈)を室温1時間反応させた。再び3回 TBS-Tで洗浄した。バンドは化学発光により検出し、ImmobilonTMWestern Chemiluminescent HRP Substrate (Millipore, #P90718)を検出薬として使用した。結果を図2に示す。KDM5C過剰発現細胞PC3でのみ、H3K4のメチル化が亢進していた。このことから、NPC-3543は細胞系でもKDM5Cを選択的に阻害することが明らかになった。
western blotting
PC3, LnCAP and MKN45 cells (5 x 105 cells/2 mL/dish) were treated with NPC-3543 and cultured for 48 hours. Cell pellets were then extracted with SDS buffer. The protein concentration of the extracted lysate was determined using the BCA protein assay. After adjusting the protein concentration of the lysate, electrophoresis was performed using a 5-20% SDS-polyacrylamide gel. Further transferred to PVDF membrane. After blocking the membrane with 5% skim milk TBS-T solution, primary antibodies polyclonal H3K4me3 antibody (Abcam, #ab8580) (1:5000 dilution), H3K4me2 antibody (CST, #9725) (1:5000 dilution), H3K4me1 antibody (Abcam, #ab8895) (1:5000 dilution), H3 antibody (Abcam, #ab1791) (1:200000 dilution), KDM5A antibody (CST, #3876) (1:1000 dilution), KDM5B antibody (CST, # 3273) (1:1000 dilution), KDM5C antibody (CST, #5361) (1:1000 dilution), mouse monoclonal α-tubulin antibody (sigma, #T8203) (1:1000 dilution) each in 5% skim milk TBS-T solution and reacted with shaking and stirring at room temperature for 1 hour. After washing the membrane three times with TBS-T, the secondary antibody ECL rabbit/mouse IgG, HRP-linked whole Anti-body (GE Healthcare Life Sciences, #NA934) (diluted 1:2500) was reacted at room temperature for 1 hour. Washed again with TBS-T three times. Bands were detected by chemiluminescence using Immobilon Western Chemiluminescent HRP Substrate (Millipore, #P90718) as detection reagent. The result is shown in figure 2. H3K4 was hypermethylated only in KDM5C-overexpressing PC3 cells. This reveals that NPC-3543 also selectively inhibits KDM5C in cell lines.

試験例2
NPC-3543投与マウスの行動評価試験(図3-6)
8週齢の雄性DBA/2マウス(以下、DBAマウス)の内側前頭前野にカニューレを留置し、NPC-3543 (100μM)あるいは溶媒を投与し、その2時間後に社会性敗北ストレス(*1)を負荷した。これを5日間連続して行い、社会性試験(*2)を施行した。
Test example 2
Behavioral evaluation test of NPC-3543-administered mice (Figure 3-6)
A cannula was placed in the medial prefrontal cortex of 8-week-old male DBA/2 mice (hereinafter referred to as DBA mice), NPC-3543 (100 μM) or vehicle was administered, and 2 hours later, social defeat stress (*1) was applied. loaded. After doing this for 5 consecutive days, a social test (*2) was conducted.

*1社会性敗北ストレス
テストマウスを攻撃性の高いCD-1マウスのケージに5分間入れる。この時、CD-1マウスはテストマウスに対して一方的に攻撃を仕掛ける(肉体的ストレス負荷)。5分経過後、CD-1マウスとテストマウスを透明なアクリル板で仕切り、24時間飼育する(心理ストレス負荷)。これを5日間連続で行った(図3)。
*1 Social defeat stress test mice are placed in a cage of highly aggressive CD-1 mice for 5 min. At this time, the CD-1 mice unilaterally attack the test mice (physical stress load). After 5 minutes have passed, the CD-1 mouse and the test mouse are separated by a transparent acrylic plate and kept for 24 hours (psychological stress load). This was done for 5 consecutive days (Fig. 3).

*2社会性試験
42 cm四方の箱に新奇マウスとしてCD-1マウスを置く(ターゲットエリア)。この箱の中にテストマウス(DBAマウス)を置き、3分間でターゲットエリアに滞在した時間をビデオトラッキングシステム(Any-Mazeソフトウェア)により測定した(図4)。
*2Sociability test
A CD-1 mouse is placed as a novel mouse in a 42 cm square box (target area). A test mouse (DBA mouse) was placed in this box, and the time spent in the target area for 3 minutes was measured by a video tracking system (Any-Maze software) (Fig. 4).

<スクロース嗜好性試験の方法>
1%スクロース溶液と通常水の入ったボトルを同時に与えた。4時間でスクロース溶液と通常水を飲んだ量を計測し、スクロース水を飲んだ割合(sucrose preference)をアンヘドニアの指標とした(図5)。通常、動物は甘いスクロースを好むが、うつ病の病態の1つであるanhedonia(無感症)の状態にある動物はスクロースに対する選択性が低下する。
<Method of sucrose preference test>
A 1% sucrose solution and a bottle of normal water were given simultaneously. The amount of sucrose solution and normal water ingested in 4 hours was measured, and the sucrose preference was used as an index of anhedonia (Fig. 5). Animals usually prefer sweet sucrose, but animals in anhedonia, one of the conditions of depression, become less selective for sucrose.

KDM5C阻害薬(NPC-3543)は、Sucrose Preference試験において、抗うつ効果を示した。このことから、KDM5C阻害剤(NPC-3543)が抗うつ薬として有効であることが示された。 A KDM5C inhibitor (NPC-3543) showed antidepressant effects in the Sucrose Preference trial. From this, it was shown that the KDM5C inhibitor (NPC-3543) is effective as an antidepressant.

<遺伝子発現解析(図6)>
ストレス脆弱性DBAマウスに軽度ストレスを5日間与えた。このときにNPC-3543 (100μM)又は溶媒(vehicle、水)を毎日投与し、次世代シーケンサーを用いた遺伝子発現解析(RNA-seq)を行い、主成分分析(PCA)とクラスタリング解析を行った。その結果、ストレス負荷によって生じた異常な遺伝子発現パターンがKDM5C阻害剤(NPC-3543)によって正常化することが明らかになった。
<Gene expression analysis (Fig. 6)>
Stress-vulnerable DBA mice were given mild stress for 5 days. At this time, NPC-3543 (100 μM) or solvent (vehicle, water) was administered daily, gene expression analysis (RNA-seq) using a next-generation sequencer was performed, and principal component analysis (PCA) and clustering analysis were performed. . As a result, it was revealed that the abnormal gene expression pattern caused by stress load was normalized by KDM5C inhibitor (NPC-3543).
