Biological Activity

In vitro: In HT29 cells, VX-11e potently inhibits cell proliferation with IC50 of 48 nM.

In vivo: In both rats and mice, VX-11e shows good oral bioavailability. In NSG mice bearing human melanoma RPDX tumors, VX-11e (50 mg/kg, p.o.) results in robust inhibition of pRSK, and inhibits tumor growth. When used in combination with BKM120, VX-11e results in significantly improved tumor growth inhibition.

Cell Experiment
Cell lines HT29 cells
Preparation method Cell proliferation is measured by 3H-thymidine incorporation. The cells are plated at a concentration of 10,000 cells/well in a 96-well plate using growth media, RPMI 1640 containing 10% FBS. Serially diluted compounds are added. The cells and compounds are incubated for 48 hours at 37°C incubator. After 48 hours, 0.4 μCi of 3H-thymidine is added to each wells for 8 hours and returned to the 37°C incubator. The cells are harvested using a Tomtec 96-well cell harvester and the CPM is determined using the Wallac 1205 BETAPLATE liquid scintillation counter. The IC50 is the 50% inhibition of contr

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.
