Product Description

Biological Activity

Description Decitabine is a potent inhibitor of DNA methylation with IC50 of 438 nM and 4.38 nM in HL-60 and KG1a cells, respectively.
Targets DNA methyltransferase (KG1a cells) [1] DNA methyltransferase (HL-60 cells) [1]
IC50 1 ng/mL 100 ng/mL
In vitro Decitabine inhibits cell growth in a dose and time-dependent manner with IC50 of approximately 438 nM and 43.8 nM for 72 hours and 96 hours exposure in HL-60 and KG1a leukemic cells, respectively. [1] A recent study shows that Decitabine exhibits high anti-proliferative and pro-apoptotic activity against anaplastic large cell lymphoma (ALCL), and inhibits [3H]–thymidine uptake in KARPAS-299 cells with EC50 of 0.49 μM. [2]
In vivo In a ALK+ KARPAS-299 murine xenograft model, Decitabine at a dose of 2.5 mg/kg causes increased apoptosis and reduced proliferation of tumor cells, and also results in demethylation of tumor suppressor p16INK4A. [2]

Protocol(Only for Reference)

Kinase Assay: [1]

DNA synthesis assay The rate of DNA synthesis is measured by the incorporation of radioactive thymidine into DNA. HL-60 and KG1a cells are suspended in 2 mL RPMI medium containing 10% fetal serum in 6-well (35 mm diameter) dishes and incubated with different concentrations of corresponding drugs for 48 hours (drugs are added simultaneously). At 48 hours, 0.5 μCi [3H] thymidine (6.7 Ci/mmol) is added to each well and incubated for an additional 24 hours. The cells are placed on GF/C glass fiber filters (2.4 cm diameter), washed with cold 0.9% NaCl, 5% cold trichloroacetic acid and ethanol. The filters containing the DNA are then dried, placed in EcoLite scintillation liquid (ICN) and the radioactivity measured using Beckman LS 6000IC scintillation counter. The IC50 is defined as the concentration of drug that inhibits 50% of the DNA synthesis of the leukemic cell lines from the dose–response curve.

Cell Assay: [1]

Cell lines HL-60 and KG1a
Concentrations 0-500 nM
Incubation Time 96 hours
Method For the growth inhibition assay, cells in log phase are placed in 5 mL of medium. Different concentrations of Decitabine are added to the medium simultaneously. Cell counts are performed at the indicated times using a model ZM Coulter Counter. The concentration that produces 50% inhibition of growth (IC50) is determined from the growth curves of the drug treated leukemic cell lines.

Animal Study: [2]

Animal Models KARPAS-299 human cells are inoculated subcutaneously into the right and left flanks of the mice.
Formulation Decitabine is dissolved in sterile PBS .
Dosages ≤2.5 mg/kg
Administration Administered via i.p.
Solubility 30% propylene glycol, 5% Tween 80, 65% D5W, 30 mg/mL
* 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.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
