Biological Activity

In vitro: The compound displays a high degree of selectivity over the alpha (>1000 fold), beta (>30-50 fold), and gamma (>15-50 fold) isoforms. Additionally, the compound causes a half-maximal inhibition of human whole blood CD19 cell proliferation between 100-300 nM. Treatment of PBMC with RP5264 results initially in a G2/M arrest followed by subsequent increase in the number of Sub G0 cells. Viability assays demonstrate that the compound causes a significant inhibition in growth as well as Akt phosphorylation of immortalized and primary leukemic cells.

In vivo: The compound exhibits good oral absorption with favourable pharmacokinetic properties in rodents. It also has an excellent safety profile.

Cell Experiment
Cell lines Multiple Myeloma resistant (MM-1R) or sensitive (MM-1S) cells
Preparation method Multiple Myeloma resistant (MM-1R) or sensitive (MM-1S) cells are incubated with desired concentrations of RP5264. Growth is assessed after 96 h by a MTT assay.
Incubation time 96 h
Animal Experiment
Animal models Female Balb/c mice
Dosages 12.5, 25, 50 mg/kg
Administration 12.5, 25, 50 mg/kg
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.
