Voreloxin

    WARNING: This product is for research use only, not for human or veterinary use.

Description: Voreloxin, also known as SNS-595 or Vosaroxin, is a s mall 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, reducing the risk of cardiotoxicity.

Technical Data

Additional Information

SNS-595 is a novel naphthyridine analog, structurally related to quinolones, a class of compounds which has not been used previously in the treatment of cancer.  Sunesis researchers conducted in vitro and cell-based studies elucidating SNS-595's mechanism of action. SNS-595 selectively intercalates DNA and poisons topoisomerase II, resulting in replication-dependent DNA damage, irreversible G2 arrest and rapid apoptosis. SNS-595's targeted DNA-topoisomerase II interactions may contribute to the broad therapeutic window observed in patients treated with SNS-595. SNS-595 avoids common drug resistance pathways and may have advantages over other topoisomerase poisons
