Abstract:
Aim To study the influence of Si-Wu De-coction (SWD ) and its active components on cyto-chrome P450 activity and mRNA expression in rats in order to provide an experimental basis for compatibility of SWD.Methods SWD and its active components were intragastrically administrated for seven days,the doses of SWD was 10 g · kg -1 · d -1 ,the doses of fructose,ferulic acid,ligustrazine,peoniflorin were 0.334,0.002,0.011 and 0.022 g·kg -1 ·d -1 ,re-spectively.After administration for seven days,rats were executed,and liver microsomes were prepared. The effects of SWD and its active components on cyto-chrome P450 in rats were investigated by hybrid probe and liver microsomes incubation method.The level of mRNA expression in liver was detected by real-time quantitative polymerase chain reaction using specific target primers for CYP450 genes.The level of protein expression of CYP2B1 was detected by Western blot. Results Compared with the control group,fructose significantly decreased the activity of CYP1A2, CYP2B6,CYP2C9,CYP2D6;ferulic acid significantly decreased the activity of CYP2C9,CYP2B6;ligus-trazine significantly decreased the activity of CYP1A2, CYP2C9,CYP2B6;peoniflorin significantly decreased the activity of CYP2D6,CYP2B6;fructose,ferulic acid,peoniflorin inhibited the mRNA expression of CYP2B1;fructose,ferulic acid,ligustrazine and peon-iflorin also inhibit the protein expression of CYP2B1. Conclusion Fructose,ferulic acid,peoniflorin inhib-it the activity of CYP2B1,decrease the expression lev-els of mRNA and protein of CYP2B1.
