[化合物調製の実施例]
調製実施例1(化合物番号CFH367−C)
同様な方法で以下の化合物を合成した。
同様な方法で以下の化合物を合成した。
同様な方法で以下の化合物を合成した。
同様な方法で以下の化合物を合成した。
実例1:ヒストン脱アセチル化酵素1,3,6(HDAC1,3,6)の阻害活性テスト実験
本発明の化合物のヒトヒストン脱アセチル化酵素1,3,6の阻害活性テストを行う。
ヒト HDAC1、HDAC3及びHDAC6、バキュロウイルス発現システムを使用することによって得られた。
Ac−Lys−Tyr−Lys(Ac)−AMC(HDAC1,3)及びBoc−lys(Ac)−AMC(HDAC6)を基質とし、蛍光検出法を使用し、96ウェルまたは384ウェル平底マイクロプレートにおいて酵素活性を測定した。基質がHDACによって脱アセチル化された後、トリプシンによって加水分解して得た生成物AMCについて、蛍光検出装置の波長355nmで励起を行い、460nm蛍光波長における蛍光信号を検出することができる。時間の経過に伴う蛍光信号の変化を検出することによって、反応の初期速度を算出する。
サンプル処理:サンプルをDMSOで溶かし、低温で保管し、最終システムにおけるDMSOの濃度が活性の検出に影響しない範囲内に制御される。
実例2:細胞レベルの抗腫瘍活性テスト実験
本発明の化合物の抗腫瘍活性テストを行い、ヒト結腸ガンHCT−116細胞株に対する化合物の生長阻害活性を測定することによって化合物の体外抗腫瘍活性を評価する。
メチルチアゾリルテトラゾリウム(MTT)比色法を使用し、該分析方法は3−(4,5−ジメチル−2−チアゾリル)−2,5−ジフェニルテトラゾリウムブロミド(MTT)を代謝還元することをベースとする。生細胞のミトコンドリアにはNADPと関る脱水素酵素が存在しており、黄色のMTTを不溶性の青紫色のホルマザン(Formazan)に還元でき、死細胞には該酵素が消えたため、MTTが還元されない。DMSOでFormazanを溶解した後マイクロプレートリーダーによって550/690nm波長の処で光密度を測定できる。
サンプル処理:サンプルをDMSOで溶解し、低温で保管し、活性の検出に影響を与えない範囲内に、最終体系におけるDMSOの濃度を制御する。
4.1:HCT−116ヒト結腸ガン細胞株における化合物の活性結果
1.実験方法及び結果
ヒストン脱アセチル化酵素阻害薬CFH367−CがMSの実験マウス動物モデルEAEの臨床症状を有効に緩和できる。EAEマウスの脊髄に対して染色を行う実験によって、CFH367−Cが末梢性免疫細胞の、特にCD4陽性T細胞のマウス中枢神経系に対する浸潤を抑制し、EAE動物ニューロンの脱髄現象を軽減し、それによって、EAEの臨床表現を緩和することができることを発見した。本研究の結果は、ヒストン脱アセチル化酵素阻害薬CFH367−CがMS疾患の治療に用いられることができ、且つさらに関節リウマチ、乾癬、全身性エリテマトーデス等を含むその他の自己免疫疾患の治療に応用されることが可能であることを表した。
