Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.

 3.750mg/ml (2.99mM) Taking the 1 mL working solution as an example, add 50 μL 75 mg/ml clarified DMSO stock solution to 400 μL PEG300, mix evenly to clarify it; add 50 μL Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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 RNA and protein synthesis inhibitor that can suppress bacterial protein synthesis. Actinomycin D is an autophagy activator, induces p53-independent cell death and prolongs survival in high-risk chronic lymphocytic leukaemia.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 cell cycle
(Cell-based assay)		 DNA repair
(Cell-free assay)
0.4 nM 0.42 μM
In vitro

Actinomycin D (Dactinomycin) markedly reduces 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 this compound. Extracellular signalregulated kinases (Erk) involved in cell-cycle arrest are found to be increased by it.
In Vivo

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

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 (dactinomycin) at 37℃. Drug treatment is carried out for 18-24 h. Since it 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
