产品介绍 Chromomycin A3, a fluorescent DNA stain and antibiotic, has been reported to strongly inhibit zinc-dependent transcriptional activity of sheep Metallothionein 1A promoter in reporter gene assays of transfected cells. This compound has also been shown to be a potent inhibitor of neuronal apoptosis induced by glutathione depletion-induced oxidative stress and DNA-damaging agent Camptothecin. Mechanistic studies suggest that Chromomycin A3 antagonizes enhanced DNA binding of the transcription factors Sp1 and Sp3 to their cognate "G-C" box, induced by oxidative stress or DNA damage. Furthermore, by inhibiting transcription, Chromomycin A3 and its structural analogs can inhibit protein biosynthesis.

别名 ;Aburamycin b;Olivomycin D;Toyomycin;Antibiotic 69895 A;Antibiotic B 599

生化机理 An antibiotic exhibiting anti-bacterial, anti-fungal and antitumor activities. Serves as a fluorescent DNA stain. Useful for the detection of protamine deficiency in sperm chromatin. The compound blocks macromolecule synthesis by a specific, reversible interaction with DNA in the presence of bivalent metal ions. Binding to DNA minor groove mediates an efficient competitive inhibition of DNA gyrase and significantly affects topoisomerase II activity

应用 Membrane-impermeant G/C-specific fluorescent DNA-binding dye. 

Antibacterial antibiotic. 

Antitumor antibiotic that inhibits RNA synthesis, especially in solid tumors.
