牛乳(Bovine milk)由来のキサンチンオキシダーゼを試験物質と3分間培養し、基質であるキサンチンを加えることにより尿酸合成の初期速度を求めた。阻害剤ない場合の初期速度対比試験物質濃度別初期速度を%阻害に換算して、50%阻害する阻害剤濃度をIC50値として求めた。本発明によると、nMのレベルで牛乳(Bovine milk)からのキサンチンオキシダーゼに対してIC50値を示す化合物が開発された。試験化合物のキサンチンオキシダーゼに対する阻害活性を表1に示す。
血漿及び肝で尿酸低下作用(ラットオキソン酸酸誘発高尿酸モデル)
本発明に係る化合物の血漿中の尿酸低下陵を評価するために、オキソン酸誘発高尿酸モデルを用いて実験を行った。
200gの雄性シロネズミ(SDラット)に、0.8%カルボキシメチルセルロース液に懸濁したオキソン酸カリウム300mg/kg(対照群、化合物投与群)を腹腔投与した。オキソン酸投与1時間後、ポリエチレングリコール400:エタノール=2:1溶液に溶かした試験化合物(化合物投与群)を10mg/kgの容量で経口投与し、1時間経過後、採血した。得られた血液から血漿を分離し、血漿中の尿酸の濃度をLC−MS/MSを用いて定量した。血漿中の尿酸濃度測定結果及び血漿中の尿酸抑制率をそれぞれ図1及び図2に示した。
