Stereoisomer of N,N'-[(2-amino-4,6-dimethyl-3-oxo-3H-phenoxazine-1,9-diyl)bis[carbonylimino[2-(1-hydroxyethyl)-1-oxo-2,1-ethanediyl]imino[2-(1-methylethyl)-1-oxo-2,1-ethanediyl]-1,2-pyrrolidine diylcarbonyl(methylimino)(1-oxo-2,1-ethanediyl)]]bis[N-methyl-L-valine]di-epsilon-lactone (SciFinder)
分子機能: Antineoplastic antibiotic that inhibits DNA-primed RNA polymerase by complexing with DNA via deoxyguanosine residues. At higher concentrations, DNA polymerase is inhibited. / 情報源: Merck-Calbiochem
研究利用: Actinomycin D and its fluorescent derivative, 7-aminoactinomycin D (7-AAD), are used as stains in microscopy and flow cytometry applications. The affinity of these stains compounds for GC-rich regions of DNA strands makes them excellent markers for DNA. 7-AAD binds to single stranded DNA; therefore it is a useful tool in determining apoptosis and distinguishing between dead cells and live ones / 情報源: http://www.fermentek.co.il/7AAD.htm
作用機序: Good evidence exists that this drug bind strongly, but reversibly, to DNA, interfering with synthesis of RNA and, consequently, with protein synthesis. / 情報源: DrugBank
薬理学: Generally, the actinomycins exert an inhibitory effect on gram-positive and gram-negative bacteria and on some fungi. However, the toxic properties of the actinomycins (including dactinomycin) in relation to antibacterial activity are such as to preclude their use as antibiotics in the treatment of infectious diseases. Because the actinomycins are cytotoxic, they have an antineoplastic effect which has been demonstrated in experimental animals with various types of tumor implant. This cytotoxic action is the basis for their use in the treatment of certain types of cancer. Dactinomycin is believed to produce its cytotoxic effects by binding DNA and inhibiting RNA synthesis. / 情報源: DrugBank
