Biological Activity

Actinomycin D (Dactinomycin) is an antibiotic found in Streptomyces microsporum with antibacterial and anti-tumor effects. Actinomycin D is an inhibitor of RNA and protein synthesis. Actinomycin D can inhibit the protein synthesis of bacteria, directly bind to the guanine groups of single-stranded or double-stranded DNA in the transcriptional initiation complex, inhibit the activity of DNA-dependent RNA polymerase, and interfere with the transcription process of DNA, thereby inhibiting mRNA synthesis. Actinomycin D inhibits DNA repair with an IC50 value of 0.42 μM.

Actinomycin D is a compound composed of a two CYCLIC PEPTIDES attached to a phenoxazine that is derived from STREPTOMYCES parvullus. It binds to DNA and inhibits RNA synthesis (transcription), with chain elongation more sensitive than initiation, termination, or release. As a result of impaired mRNA production, protein synthesis also declines after dactinomycin therapy.
