Biological Activity

Description Actinomycin D (Dactinomycin, Act D, RASP-101) is a significant polypeptide antibiotic isolated from soil bacteria of the genus Streptomyces. Actinomycin D (Dactinomycin) inhibits DNA repair and rests the cell cycle at G1 phase with IC50 of 0.42 μM and 0.4 nM, respectively. Actinomycin D is an autophagy activator, induces p53-independent cell death and prolongs survival in high-risk chronic lymphocytic leukemia.This product is a hazardous chemical (acute toxicity/flammable/skin corrosive). Please use it while wearing a protective face mask, gloves, and clothing.
Targets
autophagy [3] cell cycle [1]
(Cell-based assay)		 DNA repair [2]
(Cell-free assay)
0.4 nM 0.42 μM
In vitro

Actinomycin D markedly reduces the SMC proliferation via the inhibition of BrdU incorporation at 80 nM. This is further supported by the G1-phase arrest using a flowcytometric analysis. The protein expression levels of proliferating cell nuclear antigen (PCNA), focal adhesion kinase (FAK), and Raf are all suppressed by actinomycin D. Extracellular signalregulated kinases (Erk) involved in cell-cycle arrest are found to be increased by actinomycin D.[1]
In vivo

Actinomycin D targets survival proteins TOSO, BCL2 and MCL1 and is active in two different mouse models that are characterized by either unmutated B-cell receptor or inactive p53 function, both of which are known negative prognostic factors in CLL.[3]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    A10 cells (Vascular SMC)

  • Concentrations

    80 nM, 800 nM, 8 μM

  • Incubation Time

    18-24 h

  • Method

    Cultured SMC are starved for 24 h followed by incubation with various doses of actinomycin D at 37℃. Drug treatment is carried out for 18-24 h. Since actinomycin D is dissolved in 0.1% DMSO, a vehicle control containing DMSO is also included.
Animal Study:

[3]
  • Animal Models

    C57BL/6 wild-type mice engrafted with tumor cells from Em-TCL-1 transgenic mice

  • Dosages

    0.06 mg/kg

  • Administration

    IP
