Description

Acridine carboxamide (XR5000) is a tricyclic acridine-based (or carboxamide-based) drug with dual topoisomerase inhibitor and potential antineoplastic activities. Acridine carboxamide inhibits both topoisomerases I and II and intercalates into DNA, resulting in DNA damage, the disruption of DNA repair and replication, the inhibition of RNA and protein synthesis, and cell death. Acridine carboxamide has been used in trials studying the treatment of lung cancer and brain and central nervous system tumors. In clinical trials acridine carboxamide did not show efficacy when tested against various types of cancers.

Sample Use Guides

In Vivo Use Guide
Advanced ovarian cancer: Patients received Acridine carboxamide (XR5000) at the dose of 3010 mg/m(2) through a 120-h central venous infusion every 3 weeks.
Route of Administration: Intravenous
In Vitro Use Guide
CCRF-CEM cells were exposed to a range of concentrations of TAS-103 (0.1 to 10 uM) or Acridine carboxamide (0.1 to 100 uM) for 2 hr and then analysed using the TARDIS assay to detect drug-stabilised topo I, topo IIa, and topo IIb cleavable complexes in individual cells. These cells were sensitive to Acridine carboxamide and TAS-103 with IC50 values of 474 and 5 nM, respectively. Acridine carboxamide showed a dose-dependent increase in topo IIa FITC immunofluorescence levels, with 10 and 100 uM Acridine carboxamide giving significantly higher levels of cleavable complexes than the untreated cells. Only the highest concentration of 100 uM Acridine carboxamide showed any effect on topo IIb FITC immunofluorescence. Topo IIa transformants were found to be more sensitive (Acridine carboxamide IC50=50 uM) than topo IIb transformants (Acridine carboxamide IC50 >137 uM).
