Abstract
Description
化合物1〜3をサンプルとして、下記の要領で一酸化窒素産生抑制活性試験を行った。各サンプルをDMSOに溶解した。別途、F-12HAM培地500mLにL−グルタミン(200mM)5mL、FBS50mLを加えた培地を調製し、該倍地中のDMSOが0.2重量%になるように調製した。次に、コンフエルエントになったRAW264.7細胞50mLを調製した培地に添加し、細胞懸濁液とした。この細胞懸濁液をFalconチューブに入れた。
抑制率(%)={1−(X−Y)/(Z−Y)}×100
X:試験化合物の存在下でIFN−γとLPSにより誘導されるNO2 -の量
Y:試験化合物、IFN−γ及びLPSがない状態で誘導されるNO2 -の量
Z:IFN−γとLPSにより誘導されるNO2−の量
更に、算出した値から、サンプル化合物によるNO産生抑制活が50%阻害された濃度(IC50)を求めた。細胞生存率(Cell viability)の結果と併せて表5に示す。なお、表中、「A」はNO産生抑制率(%)を意味し、「B」は細胞生存率(%)を意味する。
評価基準
化合物1〜3をサンプルとして、Okadaらの方法に基づきラジカル消去活性試験を行った。96穴プレート(住友ベークライト社製、#8096R)に0.2M酢酸緩衝液(pH5.5)40μL、12%含水エタノール溶液120μL、ジメチルスルホキシドで溶解した試験化合物0.4μLを加えた後、0.5mM DPPH溶液40μLを加えて暗所で30分間放置した。その後、プレートリーダー(Bio−Rad社製3550プレートリーダー)により520nmの吸光度を測定した。そして、得られた測定値につき、下記計算式を用いてDPPHラジカルの消去率を算出した。更に、算出した値から、サンプル化合物によるラジカル消去活性が50%阻害された濃度(IC50)を求め、結果を表6に示した。
消去率(%)={1−(X−Z)/(Y−Z)}×100
X:試験化合物を添加したときの吸光度
Y:試験化合物を添加していないときの吸光度
Z:ジメチルスルホキシドと12%エタノール溶液のみの吸光度
