[In vitro liver microsomal metabolism of antimalarial primaquine]
1Institute of Parasitic Diseases, Chinese Academy of Preventive Medicine, Shanghai.
Abstract:
The profile of the major metabolites of primaquine produced by in vitro liver microsomal metabolism was investigated with silica gel thin-layer and high performance liquid chromatography (HPLC) analysis. The results indicated that the liver microsomal metabolism could simultaneously produce both 5-OH PQ (quinoline ring oxidation product) and CPQ (side-chain oxidative deamination product). However, the quantitative comparative study of microsomal metabolism showed that the production of 5-OH PQ was far much higher than that of CPQ.
