The effect of chloroquine and hydroxychloroquine on neutrophil superoxide release stimulated by the chemotactic tripeptide N-formyl-methionyl-leucyl-phenylalanine (FMLP) was examined. Both drugs caused time and dose dependent inhibition of superoxide release but had no effect on equilibrium binding of [3H]FMLP to its receptor. Preliminary experiments suggest that these drugs may exert their inhibitory effect on superoxide release by inhibiting the FMLP stimulated hydrolysis of phosphoinositides.
研究了氯喹和羟氯喹对趋化性三肽N-甲酰甲硫氨酰-亮氨酰-苯丙氨酸(FMLP)刺激的中性粒细胞超氧化物释放的影响。两种药物均引起超氧化物释放的时间和剂量依赖性抑制,但对[3H]FMLP与其受体的平衡结合无影响。初步实验表明,这些药物可能通过抑制FMLP刺激的磷酸肌醇水解对超氧化物释放发挥抑制作用。
