Chloroquinoxaline sulfonamide (Chloroquinoxaline), a structural analogue of sulfaquinoxaline, is a topoisomerase II alpha/beta poison. Chloroquinoxaline sulfonamide is used to control coccidiosis in poultry, rabbit, sheep, and cattle Antitumor activity . In Vitro The Chloroquinoxaline sulfonamide IC 50 for CV-1cells, obtained using an MTT cytotoxicity assay, was 1.8 mM. Chloroquinoxaline sulfonamide causes dose-dependent protein-DNA cross-links to CV-1 monkey kidney cell chromosomal DNA when drug treatment was terminated by lysis with GuHCl. Chloroquinoxaline sulfonamide-induced protein-DNA cross-links in CV-1 cells. Chloroquinoxaline sulfonamide-induced topoisomerase II-DNA cross-links. Chloroquinoxaline sulfonamide (Chloroquinoxaline), a chlorinated derivative of sulfaquinoxaline, inhibits proliferation of murine B16 melanoma cells, but only when relatively high drug concentrations (1 mM) are used. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Proliferation AssayCell Line: B16 murine melanoma cells Concentration: 10 μM, 100 μM, 1 mM Incubation Time: 24, 48, 72 hours Result: Inhibited proliferation of murine B16 melanoma cells, but only when relatively high drug concentrations (1 mM) were used. Form:Solid IC50& Target:topoisomerase II alpha topoisomerase II beta Coccidia
