On the other hand, the hepatic microsomal aminopyrine demethylase activity was obviously inhibited 2 hours after administration of the same dose of SY-801 and SY-640, while the content of hepatic cytochrome P-450 was not affected.

体外实验表明，SY-801和SY-640对正常小鼠、3-甲基胆蒽（3-MC）处理小鼠及苯巴比妥处理小鼠小鼠肝微粒体氨基比林脱甲基酶活性都具有明显的抑制作用，其中对3-MC处理小鼠肝微粒体氨基比林脱甲基酶活性抑制作用最显著。

In order to study the relation of cytochrome P-450 with the protective action of SY-801 and SY-640 against 〓-induced UDS and 3H-BP binding to nuclear DNA, the effects of SY-801 and SY-640 on liver microsomal cytochrome P-450 were studied in mice. The results indicated that the liver microsomal cytochrome P-450 concentration and aminopyrine demethylase activity were significantly increased in mice pretreated with SY-801 150mg/kg or SY-640 150 mg/kg once daily for three days.

本实验进而观察了SY-801对小鼠肝微粒体细胞色素P-450酶系的影响，结果表明SY-801和SY-640体内连续给药3天，可诱导小鼠肝微粒体细胞色素P-450含量明显增加，同时氨基比林脱甲基酶活性亦明显增加；给药1次2小时内二者均可抑制氨基比林脱甲基酶活性，而对肝微粒体细胞色素P-450含量则无明显影响。
