生物学的実施例1:ヒトDP受容体発現細胞を用いたDP受容体拮抗活性の測定
DP受容体拮抗活性の測定には、cAMP-HTRF kit(セティメディカルラボ、62AM6PEJ)を用いた。384 well plateに,各種濃度に調製した本発明化合物及びプロスタグランジンD2(最終濃度10nmol/L)を10μL/well添加した。ヒトDP受容体発現細胞を2μmoL/Lのジクロフェナク及び1mmol/LのIBMX(3―Isobutyl―1―methylxantine)を含有するリン酸バッファーで懸濁し、5000cells/10μL/wellになるように播種した。細胞播種後は、室温で1時間インキュベーションした。その後、測定キットの方法に準じてanti-cAMP Cryptate conjugate及びcAMP-d2溶液を添加し、室温で1時間インキュベーションした後、サンプル中のcAMP濃度を定量した。
本発明化合物によるDP受容体拮抗作用の強度は、10nmol/L プロスタグランジンD2刺激で増加するcAMP産生量に対する抑制率から算出されるIC50値(本発明化合物非存在下におけるcAMP産生量を50%阻害するのに要する本発明化合物の濃度)として表した。表1に本発明化合物のDP受容体拮抗活性を示す。
本発明化合物は、DP受容体に対し強力な拮抗活性を示した。
(1)CSF採取
5個の被験物質を混和し、各被験物質の投与量が3mg/5mL/kgとなるように被験物質溶液を調製した。媒体は5%DMSO 20%コリフォールHS15/プロピレングリコール(7:3)を使用した。日本チャールス・リバーより購入した雄性の8~10週齢のWistarラットに被験物質溶液を経口投与した。投与3時間後、ラットに麻酔をかけ、大槽穿刺によりCSFを採取した。採取に使用したシリンジでCSFと等量のエタノール(wako)を取り、洗い込みをすることでシリンジに吸着した化合物を回収した。
(2)測定
内部標準物質としてCandesartan(TRC)を用い、得られたCSFサンプル10μLにアセトニトリル40μL、Candesartan含有アセトニトリル/エタノール(7:3)160μLを添加して、撹拌した。検量線作成用に、血漿10μLに化合物溶液40μL、Candesartan含有アセトニトリル/エタノール(7:3)160μLを添加して、攪拌した。各溶液を除蛋白用フィルタープレートに全量を移して吸引濾過した。得られたろ液をアセトニトリル/水(1:1)で適宜希釈し、測定に用いた。測定では、それぞれ同一マトリックスで検量線用標準試料を調製し、同様に分析した。測定は以下の条件で行った。
液体クロマトグラフィーシステム:Prominence UFLCXR(島津製作所)、
カラム:Shim-pack XR-ODSII 2.0 mm ID×75 mm(島津製作所)、
カラム温度:40℃、
移動相:A:0.2%ギ酸5mmol/L酢酸アンモニウム水溶液、B:アセトニトリル、
グラジエントプログラム:
時間(移動相B(%)):0分(10)→1.5分(90)→3.0分(90)→3.1分(10)→4分(10)、
流量:0.5mL/min
質量分析システム:API4000、API5000(AB SCIEX)
(3)解析
解析ソフトウェアAnalyst ver. 1.5.2(AB SCIEX)を用いて検量線用標準試料の測定で得られたピーク面積比(被験物質のピーク面積/内部標準物質のピーク面積)から回帰式を算出した。測定試料についてもピーク面積比を求め,回帰式に代入して定量値を算出した。平均値及び標準偏差の算出では、定量下限未満のポイントは0として計算した。
結果を表2に示す。
比較化合物として、先行技術文献の特許文献2中の実施例13―24に記載の化合物を用い、CSF中化合物濃度を測定したところ、4.8ng/mLであった。本発明化合物のCSF中化合物濃度は比較化合物よりも高く、良好な中枢移行性を示した。
ラットの脳及び頸部筋に慢性電極を留置し、脳波及び筋電図を測定可能なラットを作製した。一週間以上の回復期間の後、音及び電気的ノイズを遮断したシールドボックス内で、ラットと生体信号増幅装置を接続した。測定ケージ内で一時間以上馴化した後、種々の用量の本発明化合物をラットに単回経口投与し、経口投与後6時間の脳波及び筋電図を記録した。測定終了後のラットは、その都度飼育ケージに戻し、媒体及び各化合物の評価は一週間以上の休薬期間を設けて実施した。
記録した脳波及び筋電図はSleepSign Ver.3を用いて解析し、10秒ごとのエポックに分割し、脳波及び筋電図の特徴、並びに脳波の各周波数成分のスペクトル解析結果を参考に、覚醒・ノンレム睡眠・レム睡眠のいずれかにステージ判定した。ステージ判定は、高振幅の筋電図が認められる場合は「覚醒」、高振幅徐波及び低振幅の筋電図が認められる場合は「ノンレム睡眠」、シータ波成分を含む低振幅の脳波及び低振幅の筋電図が認められる場合は「レム睡眠」と判定した。ノイズなどでステージ判定が困難なエポックは、前のエポックの判定結果に準拠した。
睡眠・覚醒状態を判定後、本発明化合物投与群の投与後6時間の総覚醒時間と媒体投与群の投与後6時間の総覚醒時間の差を覚醒時間延長作用の指標として表した。
本発明化合物の覚醒時間延長作用を評価した結果、例えば実施例化合物8および実施例化合物12は、3mg/kgの用量でそれぞれ48分及び60分の覚醒時間延長作用を示し、本発明化合物は睡眠覚醒障害治療剤として有用であることを示した。
本発明に用いられる代表的な製剤例を以下に示す。
{4-クロロ-3-[(2,6-ジメチル-4-{2-[(2R)-オキサン-2-イル]エトキシ}ベンゼン-1-カルボチオイル)アミノ]フェニル}酢酸(100g)、カルボキシメチルセルロースカルシウム(20g)、ステアリン酸マグネシウム(10g)および微結晶セルロース(870g)を常法により混合した後打錠することにより、一錠中に10mgの活性成分を含有する錠剤約1万錠が得られる。
