Biological Activity

Azacitidine (Vidaza) is used in the treatment of myelodysplastic syndrome. Cells in the presence of azacitidine incorporate it into DNA during replication and into RNA during transcription. The incorporation of azacitidine into DNA or RNA inhibits methyltransferase thereby causing demethylation in that sequence, affecting the way that cell regulation proteins are able to bind to the DNA/RNA substrate.

Cell Experiment
Cell lines Leukemia L1210 cell
Preparation method  5 mL of L1210 cells (5 × 103 cells/mL) are incubated with Azacitidine at 37 ℃ for 3 days. Cell number is determined twice a day for 3 days by means of a Model A Coulter counter.
Concentrations 0.15 μg/mL
Incubation time 3 d
Animal Experiment
Animal models BDF1 mice bearing lymphoid leukemia L1210
Formulation 0.85% NaCl solution
Dosages 3 mg/kg
Administration  i.p.
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

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.
