• 体外研究: 托美汀(0.25mm)对大鼠脑匀浆脂质过氧化无明显影响。托美汀(0.25,0.5,0.75,1mm)在大鼠脑匀浆中显示自由基清除特性,但不产生超氧阴离子[3]。托美汀(0.001-100μM)对HT-29结肠癌细胞具有一定的抗癌活性,且呈剂量依赖性[4]。托美汀(0-100μM)对成骨细胞生长无影响[5]。
• 体内研究: 托美汀(30100mg/kg；灌胃；单次给药或每日两次,持续3天和14天)在单次给药后4h显示出最大的溃疡形成作用,而在体重180-200g的雄性Wistar大鼠中,重复给药3天和14天后,其溃疡作用显著降低。托美汀在100 mg/kg时引起胃损伤[2]。托美汀(5 mg/kg,每天两次,共5天)预处理可显著减轻喹啉酸(QA)诱导的神经毒性[3]。
