Abstract:  AIM: To study the mechanism of antimalarial action of nitroquine.METHODS:Intraerythrocytic P. yoelii was cultured by the method of Trager and Jensen. The amount of [ 3H] ethanolamine incorporation was measured as an index of the phospholipid synthesis.DPH was used as a probe to measure the plasmodial fluorescent polarization.RESULTS:The incorporation of [ 3H] ethanolamine into the P.yoelii infected erthrocytes was markedly inhibited by nitroquine. The plasmodial membrane polarization and viscosity were significantly increased by nitroquine.CONCLUSION: Nitroquine could inhibit the phospholipid synthesis and decrease the membrane fluidity of P.yoelii .

Key words: Plasmodium yoelii, membrane phospholipid, biosynthesis, membrane fluidity
