Streptonigrin is a phenylpyridylquinoline originally isolated from S. flocculus with diverse biological activities.{46268,46267,46269,46265,46266,46270} Streptonigrin (2.5-12.5 ?M) induces DNA cleavage by calf thymus topoisomerase II in a concentration-dependent manner.{46268} It induces phage production in S. typhimurium when used at concentrations ranging from 1 to 10 ?g/ml.{46267} Streptonigrin (10 ?g/ml) inhibits DNA synthesis in and reduces survival of S. typhimurium bacteria. Streptonigrin is bactericidal against E. coli in an iron-dependent manner, an effect that is blocked by the iron chelators deferoxamine (Item No. 14595) and orthophenanthroline.{46269} Streptonigrin (40 nM) is cytotoxic to human HT-29 colon carcinoma cells but not to BE colon carcinoma cells in which NAD(P)H:quinone oxidoreductase is not expressed.{46265} Streptonigrin (0.001-0.1 ?g/ml) inhibits mitosis and induces chromatin breaks in human leukocytes in a concentration-dependent manner.{46266} In vivo, streptonigrin (0.05 mg/kg, i.p.) increases the mean survival time in rats infected with Rauscher virus.{46270}
