Biological Activity

Biricodar (VX-710, Incel) is a clinically applicable modulator of P-glycoprotein (Pgp) with potential chemosensitizing activity. Biricodar blood concentration at the time of mitoxantrone administration averaged 4.52 microg/ml. In 8226/Dox6 cells (Pgp), Biricodar (VX-710) increased mitoxantrone and daunorubicin uptake by 55 and 100%, respectively, increased their retention by 100 and 60%, respectively, and increased their cytotoxicity 3.1- and 6.9-fold, respectively. Biricodar (VX-710) modulates Pgp, MRP-1, and BCRP(R482), and has potential as a clinical broad-spectrum MDR modulator in malignancies such as the acute leukemias in which these proteins are expressed.

Cell Experiment
Cell lines HL60 cells line
Preparation method Cytotoxicity Assays.
To study cytotoxicity in suspension cell lines, cells were plated in 96-well tissue culture plates at a density of 10,000 cells/well in RPMI 1640 supplemented with 10% FCS, 2 mm l-glutamine, 20 units/ml penicillin, and 20 μg/ml streptomycin. Drug was added to the culture medium to achieve final concentrations of 0.3 nm to 10 μm, with half-log increments, with and without VX-710 at a final concentration of 2.5 μM. The final volume of medium per well was 100 μl. Cells were incubated for 96 h at 37°C in a fully humidified atmosphere of 5% CO2 in air. Cell growth was assessed by the WST-1 colorimetric assay (Roche Diagnostics GmbH, Mannheim, Germany; Ref. 29 ), performed according to the manufacturer’s instructions. Briefly, 10 μl of WST-1 were added to each well, and culture plates were returned to the incubator for an additional 4 h. Subsequently, the absorbance at 450 nm (A450) and 600 nm (A600, background) was read for each well using a Microtek multiwell plate reader. Each drug exposure condition was assessed in quadruplicate.

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 Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
