Biological Activity

Decitabine is a potent DNA methyltransferase inhibitor with IC50 of 438 nM and 4.38 nM in HL-60 and KG1a cells, respectively. Decitabine is a hypomethylating agent. It hypomethylates DNA by inhibiting DNA methyltransferase. The DNA methyltransferase inhibitor Decitabine is able to reactivate genes silenced by DNA methylation and has been shown to be a very potent epigenetic compound in several hematological malignancies. Decitabine exhibits high antineoplastic activity against anaplastic large cell lymphoma (ALCL), a rare CD30 positive non-Hodgkin lymphoma of T-cell origin. The combination of Decitabine with TSA or depsi produced a greater inhibition of growth and DNA synthesis and a greater loss of clonogenicity than either agent alone. Decitabine is highly efficient against ALCL and warrants further clinical evaluation for future therapeutic use. In clinical trials, Decitabine was demonstrated to be an active antileukemic agent.

Conversion of different model animals based on BSA (PMID: 27057123)

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 Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the K_m factor for a mouse and then divide by the K_m factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
