Inhibition of oxidative metabolism in rabbit polymorphonuclear leukocytes by triphenyltin chloride.

Treatment of rabbit polymorphonuclear leukocytes (PMN) with triphenyltin chloride (TPTC1) inhibited chemiluminescence generation stimulated by particulate stimulus, zymosan, or soluble stimuli, concanavalin A + cytochalasin D. Superoxide anion (O 2 − ) production was also inhibited, indicating that the inhibition involved inhibition of early oxidative metabolic process(es). The direct inhibition of the activation process of the oxidative burst was established by the experiments showing that a) chemiluminescence generated by xanthine oxidase-acetaldehyde system was not inhibited by TPTC1, b) washing the PMN after the treatment with TPTC1 did not affect the results of chemiluminescence, and c) there was no change in cell viability after the treatment with TPTC1.
