上記の実施例1から実施例3のいずれかの実施例、及び一般合成法に記載したスキームA~Dの合成法を参考にして、化合物番号A2~A14を合成した。
試験化合物をDMSO(シグマ社製)に20mMの濃度になるように溶解した後、使用時の目的の濃度に調製して用いた。
ヒトURAT1(hURAT1)完全長cDNA(Origene社製、NCBI Reference Sequence:NM_144585)を発現ベクターpCMV6-Kan/Neo(Origene社製)にサブクローニングし、リポフェクタミン2000(インビトロジェン社製)を用いたリポソーム法により、ヒトURAT1遺伝子をヒト胎児腎由来細胞(HEK293細胞)に導入し、geneticin耐性によりヒトURAT1遺伝子を発現したHEK293細胞を選別した。14Cで標識された尿酸が細胞内に輸送されることを指標に、ヒトURAT1遺伝子が機能を発現していることを確認した。
ヒトURAT1発現HEK293細胞を、24穴細胞培養ディッシュに3×105個/mL/wellになるように播種し、10%ウシ胎児血清を含むダルベッコ改変イーグル培地(D-MEM培地)で37℃、2日間培養した後、以下の尿酸輸送阻害試験を行った。
URAT1特異的な尿酸輸送を示す放射活性(実施例化合物無添加(DMSO添加)でのヒトURAT1発現細胞HEK293細胞における放射活性)を100%として、実施例化合物各濃度における尿酸輸送率(% of control uptake)を算出し、尿酸輸送率が50%に阻害される実施例化合物濃度(IC50)を求めた。その結果を次の表に示す。なお、表中の記号(*、**、***)は以下の阻害活性値を表す。
IC50≦0.2μM:***
0.2μM<IC50≦2μM:**
2μM<IC50≦20μM:*
フサオマキザルに0.5%メチルセルロース液に縣濁した試験化合物(3mg/kg~30mg/kg)をディスポーザブルカテーテル及び注射筒を用いて鼻腔から胃内に投与した。投与前、投与後30分、1時間、2時間、4時間、8時間、12時間及び24時間に血液を、投与直後から4時間、投与後4時間から8時間、投与後8時間から16時間、投与後16時間から24時間の間の尿サンプルを採取した。採取した血液と尿サンプル中の尿酸及びクレアチニンの濃度を自動分析装置(日本電子株式会社)により測定した。尿酸はLタイプワコーUA・F(和光純薬工業)、クレアチニンはLタイプワコークレアチニン・F(和光純薬工業)を用いて測定した。血中及び尿中の尿酸濃度から尿酸クリアランスを、同様にクレアチニン濃度からクレアチニンクリアランスを算出し、尿酸排泄率を下式により求めた。
尿酸排泄率(%)=(尿酸クリアランス/クレアチニンクリアランス)×100
以上の結果から、本発明のピラジン誘導体が優れた尿酸排泄促進作用を有することが示される。
