what is Actinomycin D used for :
Actinomycin D is one of the older chemotherapy drugs which has been used in therapy for many years. Actinomycin D is marketed as red, highly hygroscopic crystallic powder. Actinomycin D solution is a clear, yellow liquid which is administered intravenously and most commonly used in treatment of the following cancers: Gestational Throphoblastic cancers, Testis, Wilm's Tumor, Rhabdomyosarcoma, Ewing's Sarcoma
General Remarks :
The structure was determined by atomic structure and amino acid sequence.
"Dactinomycin is an antibiotic used for its antineoplastic properties in the treatment of various malignant neoplasms including Wilm's tumour, and the sarcomas. Adverse effects include bonemarrow depression and gastrointestinal toxicity; it is extremely irritating and extravasation produces severe tissue damage."5
The compound inhibits the proliferation of cells in a nonspecific way by forming a stable complex with double-stranded DNA (via deoxyguanosine residues), thus inhibiting DNA-primed RNA synthesis. It also causes single-strand breaks in DNA.5,6,10 It is used in cell culture as a selection agent; suggested working concentrations range from 0.01 to 2 mg/mL, but typically 1 mg/mL.4
Actinomycin D binding to yeast in ribosomal RNA has been studied.11 The sensitivity of various strains of E. coli to actinomycin D and the mechanism of binding has been studied.12,13
Actinomycin D is a highly toxic, carcinogenic, teratogenic and mutagenic compound, and a possible sensitizer. Please consult the Material Safety Data Sheet for appropriate handling.3
Products A1410 and A4262 differ slightly in purity. Sigma offers A9415 (cell culture tested) and a water-soluble formulation A5156. Each vial contains 1 mg actinomycin D and 49 mg mannitol.
