  Background: Batracylin is a heterocyclic arylamine topoisomerase inhibitor with preclinical anticancer activity. Marked species differences in sensitivity to the toxicity of batracylin were observed and attributed to differential formation of N-acetylbatracylin by N-acetyltransferase. A Phase I trial of batracylin in cancer patients with slow acetylator genotypes identified a dose-limiting toxicity of hemorrhagic cystitis. To further explore the metabolism of batracylin and N-acetylbatracylin across species, detailed studies using human, rat, and dog liver microsomal and hepatocyte preparations were conducted. Methods: Batracylin or N-acetylbatracylin was incubated with microsomes and hepatocytes from human, rat, and dog liver and with CYP-expressing human and rat microsomes. Substrates and metabolites were analyzed by HPLC with diode array, fluorescence, radiochemical, or mass spectrome.. View More»
