A small molecule and a naphthyridine analogue with antineoplastic activity. Vosaroxin intercalates into DNA in a site-specific manner and blocks the re-ligation process carried out by topoisomerase II during DNA replication. As a result, inhibition of DNA replication, RNA and protein synthesis occurs, followed by cell cycle arrest at G2 phase and induced p53-independent apoptosis. This agent shows a favorable toxicity profile in several aspects: it does not generate reactive oxygen species, as do anthracyclines, hence reducing the risk of cardiotoxicity; it is not a P-glycoprotein (P-gp) substrate, and thereby evades the common mechanism for multidrug resistance; and it has limited distribution to normal tissues and a more chemically stable molecular structure. Check for active clinical trials using this agent. (NCI Thesaurus)
