Abstract:Adriamycin (ADR) is a drug with relatively selective cardiotoxicity. The present study was designed to investigate its distribution into heart subcellular components and correlate such distribution with proposed loci of cardiotoxicity. Uptake of [3H]ADR by mouse ventricular slices was linear for 30 min and plateaued thereafter. The uptake was temperature dependent, being linear from 0° to 45°C. Uptake was also linear over an ADR concentration range of 0.59–8.85 times 10-4 M and increased with wet weight of tis… Show more
