Biological Activity

In vitro: PF-4989216 significantly inhibits cell viability in SCLC cells with a PIK3CA mutation, such as NCI-H69, NCI-H1048, and Lu99A cells. PF-4989216, via PI3K signaling inhibition, blocks cell-cycle progression and reduces cell transformation in SCLCs. In SCLCs with PIK3CA mutation, PF-4989216 induces BIM-mediated apoptosis. In vivo: In SCID mice bearing NCI-H69 or NCI-H1048 xenograft tumors, PF-4989216 (350 mg/kg, p.o.) inhibits PI3K phosphorylation signaling and induces antitumor activity.

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.
