Beschreibung

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.

Yellow powder

Verwenden

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.

Allgemeine Beschreibung

Chemical structure: aureolic acid

l?uterung methode

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.]
