Aclacinomycin A stabilizes topoisomerase I covalent complexes.

Abstract

Aclacinomycin A (aclarubicin) is an anthracycline anticancer agent with demonstrated activity against both leukemias and solid tumors. Previous results suggested that a major activity of aclacinomycin A is the inhibition of topoisomerase II catalytic activity. We have applied a yeast system to test whether aclacinomycin A is a topoisomerase II inhibitor in… (More)
