ABSTRACT
To elucidate the compatibility principle of Yupingfeng powder, a cocktail probe substrates approaches were developed. The enzymatic activity of cytochrome P450 from rat liver microsome was evaluated after being interfered with 7 prescriptions of Yupingfeng powder, which was designed according to the decomposed recipes design of traditional Chinese medicine. In vitro test, rat liver microsome incubation system was utilized to detect the 50% inhibitory concentrations of Yupingfeng powder with the decomposed recipes to cytochrome P450 (CYP1A2, CYP2A6 ,CYP2C9, CYP2C19, CYP3A4) enzyme. The CYPs IC50 value of Yupingfeng powder with different compatibility were greater than crude drug 1.0 g x L(-1), which indicated that all Yupingfeng powder prescriptions had no significant inhibitory activity to cytochrome P450. For CYP1A2, CYP2C19, CYP3A4, the IC50 value of Yupingfeng powder with the decomposed recipes had a tendency to increase, compared with the major impact factor from Yupingfeng powder. For CYPs, the detected IC50 of Yupingfeng powder with the decomposed recipes tended to decrease, compared with the linearly predicted value. From the point of view of the impact of drugs on the metabolic activity, the compatibility of Yupingfeng powder has certain advantages and reasonable.
