Abstract

The effect of adriamycin on human and mouse CFUGM was examined at concentrations and times suggested by plasma clearance data derived from the results of a number of published studies. Our results suggest that the high concentrations of drug present in the plasma for short periods of time following infusion are only weakly cytotoxic towards the CFUGM when incubated for similar times. In contrast, there was a considerably greater cytotoxic effect when the drug was examined at low concentrations for periods similar to those described for the terminal phase of adriamycin clearance. The principal metabolite, adriamycinol, was poorly cytotoxic.

摘要

根据多项已发表研究结果得出的血浆清除数据所建议的浓度和时间,检测了阿霉素对人及小鼠粒-巨噬细胞集落形成单位(CFUGM)的影响。我们的结果表明,输注后短时间内血浆中存在的高浓度药物,在类似时间孵育时,对CFUGM的细胞毒性较弱。相比之下,当以低浓度检测药物并在与阿霉素清除末期相似的时间段内进行观察时,细胞毒性作用要大得多。主要代谢产物阿霉素醇的细胞毒性较弱。
