While structurally related to etoposide, TOP-53 is significantly more toxic to non-small cell lung cancer cells, more active at generating chromosomal breaks, and displays improved cellular uptake and pharmacokinetics in animal lung tissues. It has a role as an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor and an antineoplastic agent. It is a furonaphthodioxole, an organic heterotetracyclic compound, a tertiary amino compound, a member of phenols and a gamma-lactone."}]
