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[1]. Antitumor activity[2].
The Chloroquinoxaline sulfonamide IC50 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[1].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[2].
