| Hazard Information | Back Directory | [Description]
Chromomycin A3 is an anthraquinone antibiotic and antitumor agent isolated from S. griseus that is used as a fluorescent probe for DNA with excitation/emission spectra of 445/575 nm. Its DNA binding is specific to two or more contiguous GC base pairs, which makes it suitable for characterizing heterochromatin in plants with species-specific AT:GC ratios. Chromomycin A3 is cytotoxic against non-small cell lung cancer and cervical cancer in vitro (IC50s = 1, 42, 60, and 40 nM for HCC44, A549, ME180, and HeLa cells, respectively). It also inhibits oxidative stress- and DNA damage-induced neuronal injury by enhancing Sp1 and Sp3 transcription factor binding. | [Chemical Properties]
Yellow powder | [Uses]
Chromomycin A3 is the major component of the chromomycin complex of the aureolic acid class, isolated from several Streptomyces species, and first reported in 1960. Chromomycin A3 exhibits a broad biological profile as an antibacterial, antifungal and antitumour agent. It binds reversibly to GC-specific DNA ligand in the minor groove which inhibits transcription, DNA gyrase and topoisomerase II activity. The intense UV spectrum and strong fluorescence makes chromomycin a useful stain for DNA. | [Uses]
Fluorescent DNA stain in flow cytometry and karyotype analysis of chromosomes. | [Definition]
ChEBI: Chromomycin A3 is a chromomycin. | [General Description]
Chemical structure: aureolic acid | [Biochem/physiol Actions]
Chromomycin A3 from Streptomyces griseus is an antibiotic exhibiting anti-bacterial, anti-fungal and antitumor activities. It serves as a fluorescent DNA stain. It is 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. | [Purification Methods]
Dissolve the antibiotic (10g) in EtOAc and add to a column of Silica Gel (Merck 0.05-0.2microns, 4x70cm) in EtOAc containing 1% oxalic acid. Elute with EtOAc+1% oxalic acid and check fractions by TLC. Pool fractions, wash with H2O thoroughly, dry and evaporate. Recrystallise the residue from EtOAc. The heptaacetate has m 214o, [] D -20o (c 1, EtOH). [Miyamoto et al. Tetrahedron 23 421 1967, Harada et al. J Am Chem Soc 91 5896 1969, Beilstein 17/5 V 673.] | [References]
