Biological Activity

Tandutinib (MLN518) is a potent, ATP-competitive and reversible inhibitor of Type III receptor tyrosine kinases (RTKs). In vitro, Tandutinib (MLN518) inhibits FLT3, c-KIT and PDGFRß with a median IC50 of approximately 30 nM. Tandutinib inhibited FLT3 phosphorylation, downstream signaling and malignant growth in vitro and in animal models. In cellular assays, Tandutinib inhibited the autophosphorylation of these receptors with an IC50 of approximately 200 nM. Tandutinib (MLN518) is quite selective; of the other receptor tyrosine kinases tested, only CSF-1R was inhibited to any appreciable degree. Based on Tandutinib's activity against the FLT3 receptor, Tandutinib was tested against a panel of clinically isolated FLT3 ITD gain of function mutants expressed in BaF3 cells. Both the W51 mutant and the WT FLT3 receptor showed a significant inhibition of receptor autophosphorylation with Tandutinib treatment. In studies of 5 different FLT3/ITD expressing cells, Tandutinib inhibited cell growth with an IC50 of 10-30 nM in all cases.

Cell Experiment
Cell lines AML cells expressing FLT3-ITD
Preparation method AML cell lines HL60 (AML-M3) and AML193 (AML-M5), KG-1, KG-1a, THP-1, and ALL cell line RS4;11 were purchased from ATCC (Bethesda, MD). Cells (initial count of 0.3* 105–1.0 *105) were washed three times in RPMI 1640 medium and plated in 1 ml of complete growth media (without IL-3 for the Ba/F3 cells) in the presence of increasing concentrations of CT53518 (0.004–30 μM). Cells were grown for 3–7 days in tissue culture, and viable cells, determined by Trypan blue dye exclusion, were counted.
Concentrations 0.004-30 μM
Incubation time 3 days
Animal Experiment
Animal models Ba/F3 nude mouse model of FLT3-ITD-mediated leukemia
Formulation 0.5% methyl cellulose
Dosages 60 mg/kg BID day 7-57
Administration oral gavage
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.
